Section 1
Project Description
1.1 Introduction
Union County Public Works (UCPW) tasked CDM in 2006 to evaluate the Union
County East Side Sewer System to develop a conceptual design for system
improvements in response to sewer system overflows. The objectives of the
recommended improvements are to provide the necessary sewer system upgrades to
prevent overflows within the existing sewer system in order to improve water quality
and public health and safety, and to the extent possible, maximize Union County's
2.65 MGD/6.63 MGD average day/peak day allocation to the City of Monroe's
WWTP.
1.2 Project Location
The East Side Sewer System serves the towns of Wingate and Marshville, the area
along US 74 east of Monroe, and the Pilgrims Pride industrial facility. The system
consists of gravity sewers, force mains, and three pump stations that convey collected
wastewater to the City of Monroe WWTP (See Figure 1-1).
1.3 Project Description
The proposed project consists of approximately 14,300 lineal feet of 24-inch diameter,
8,900 lineal feet of 18-inch diameter, and 14,800 lineal feet of 16-inch diameter sewer
force main, which begins at the existing Pump Station No. 3 (PS3) and follows existing
sewer force main to the City of Monroe Wastewater Treatment Plant (WWTP). At
Pump Station No. 3, the existing vertical shaft horizontal solids handling pumps will
be replaced with dry -pit submersible pumps of increased discharge head (TDH) to
convey a firm pumping capacity of 1,735 gpm. The two existing 1,220 gpm pumps at
Pump Station No. 2 (PS2) will be replaced with two new 1,220 gpm dry -pit
submersible pumps. At each of the three pump stations, an exterior bypass pumping
connection will be installed and the existing magmeters will be relocated from the
interiors into new exterior below -grade meter vaults. In addition, a second exterior
below -grade magmeter will be added and the existing standby generator will be
replaced at Pump Station No. 3.
Most of the project will be constructed in existing sewer easement and road right-of-
ways, which are already cleared and maintained. The excavation depth and width
will vary somewhat depending on the pipe diameter, changes in topography, location
of existing utilities, and various obstructions, however, the typical depth of cover will
be 3 feet. The total disturbed area for the project will be approximately 22 acres, but
only small portions of this total will be disturbed at one time. The permanent
construction easement will be 15 feet wide and the temporary construction easement
varies from between 5 feet and 15 feet, depending on the pipe diameter.

Section 2
Purpose and Need for Proposed Project
The primary objective of this project is to reduce/eliminate the SSOs at the existing
pump stations by providing pumps at PS3 that are sized to meet the Pump Station
Reliability requirements and re -piping the force main system from PS3 and PS2 so
that each of the pump stations pump in parallel directly to the Monroe WWTP. The
existing Union County East Side Sewer system consists of three pump stations that
are served by sewers owned by Union County and surrounding municipalities. The
existing three pump stations pump in series and deliver flow to the City of Monroe
WWTP through a 14-inch diameter force main. This system experiences SSOs due to
excessive inflow and infiltration within the municipalities' sewer collection system.
As a result, none of the three pump stations are capable of conveying peak hourly
flows with one pump out of service per the Pump Station Reliability requirements of
the 15A NCAC 2T rules. UCPW has received Notice of Violations (NOVs) from the
North Carolina Department of Environment and Natural Resources (NCDENR)
regarding the SSOs. The most recent NOV is included in Appendix A.

Section 3
Existing Environment
This Section identifies natural, cultural, and physical resources prevalent in the study
area. The purpose of this overview is to identify those resources or areas that would
need consideration in the planning phase.
3.1 Topography
Most of the pipeline route is characterized by relatively flat (0 to 2 percent slopes)
with slopes greater than 26 percent found at the Ray's Branch crossing. Elevations
along the route range from approximately 448 feet above sea level at the Ray's Branch
crossing to around 592 feet to the east of the Monroe Ansonville/Ansonville/Austin
Grove Church intersection.
3.2 Soils
According to the Union County soil survey, soils along the sewer system route consist
primarily of Badin channery silt loam (BaB), Badin channery silty clay loam (BdB2),
Chewacla silt load (ChA) and Cid channery silt loam (CmB).
3.3 Land Use
The project area is characterized primarily by agricultural farmland and with some
residential development and commercial and light industrial areas. The proposed
sewer system is located within or adjacent to existing NCDOT right-of-way. The
proposed pump station improvements work will be located within the properties of
the existing three pump stations owned by Union County.
3.4 Wetlands
Field investigations indicate that no wetlands exist on the project site.
3.5 Prime or Unique Agricultural Lands
No prime or unique agricultural lands are known to exist in the East Side Sewer
System project area.
3.6 Public Lands and Scenic, Recreational, and State
Natural Areas
The East Side sewer is not routed through any public lands or scenic, recreational, and
State natural areas.

Section 3
Existing Environment
3.7 Areas of Archaeological or Historical Value
Based on correspondence with the North Carolina Department of Cultural Resources
Division of Historical Resources (DHR), there are no locally designated sites of
historical or architectural importance in the general area of the project. Copy of
relevant correspondence with DHR is included in Exhibit B.
3.8 Air Quality
Air quality in Union County, NC is 49 on a scale to 100 (higher is better). This is based
on ozone alert days and number of pollutants in the air, as reported by the EPA. At
the end of 2004, Union County, along with other 31 North Carolina counties, was
designated nonattainment for EPA's health -based standards for 8-hour ozone
pollution.
3.9 Noise Levels
Noise along the East Side Sewer System area generally consists of vehicular traffic
from the roads in the area. The project area is characterized primarily by agricultural
land with some residential development and commercial and light industrial areas.
The three pump stations contain pumps that produce some noise when they are in
operation but are not in close proximity to residential areas.
3.10 Water Resources
3.10.1 Surface Water
In order to construct the sewer system improvements, the sewer will cross an
unnamed tributary to the Richardson Creek, the Ray's Fork and the Meadow's
Branch. The unnamed tributary is less than 8 feet wide, the Ray's Fork is
approximately 20 feet wide, and the Meadow's Branch is approximately 12 feet wide.
The impact lengths are 20 feet, 16 feet and 15 feet, respectively.
The North Carolina Department of Environment and Natural Resources (DENR)
Division of Water Quality classifies Richardson Creek, Ray's Fork and Meadow's
Branch as Class C surface waters. The best usage of Class C waters is fishing. These
waters shall be suitable for fish, shellfish, and wildlife propagation and survival.
The water quality shall be suitable for primary and secondary contact recreation,
although other factors may limit the use for these purposes.
3.10.2 Groundwater
The groundwater in the subject property area is not a source of potable drinking
water.

Section 3
Existing Environment
3.11 Forest Resources
The majority of the proposed sewer system improvements project route is within or
adjacent to an existing, disturbed sewer right-of-way. Forest resources occur along
the sewer route along the borders of streams. The areas are generally characterized
by pines and mixed hardwoods.
3.12 Shellfish or Fish and Their Habitats
The streams likely provide habitat for a variety of fish species common to Union
County. The streams are bordered by forested floodplains, residential developments,
and industrial and commercial areas. The North Carolina Natural Heritage Program
(NHP) reports that it has no records of known rare, threatened, or endangered species
in or within 1 mile of the project area.
3.13 Wildlife and Natural Vegetation
The majority of the impact area is mainly rural, agricultural area within or adjacent to
existing road right-of-ways. Vegetation consists of landscaped yards and weeds and
other opportunistic species in the abandoned areas. According to the North Carolina
Natural Heritage Program (NHP) and US Fish and Wildlife Service (FWS) databases,
three species that occur in Union County are federally protected. A review of the
Natural Heritage Program's GIS records (May 4, 2010) found no reports of these
protected species occurring at or within a 1-mile radius of the project area. FWS,
however, has requested that a species survey be performed to determine if Michaux's
sumac or Schweinitz's sunflower can be found within the project area. The results of
this study will be forwarded to NCDENR.

Section 4
Environmental Consequences/Mitigation
4.1 Topography
Construction and operation of the East Side Sewer system improvements project will
have no significant effect on the topography along the pipeline route. Existing
ground contours will be re-established after the pipeline is installed. Roads will be
repaved, and open areas will be reseeded.
4.2 Soils
There will be no adverse impacts to the soils in the project area. Soil that is excavated
during construction of the sewer system improvements project will be returned to the
trench as backfill after the pipe is installed (some soil will be disposed of off -site).
Existing contours will be restored along the route, and the ground will be reseeded or
repaved to match conditions prior to construction.
4.3 Land Use
Construction of the proposed project will not result in any direct, long-term changes
in land use since the pipeline will be installed entirely underground and the existing
ground contours will be restored. During construction, some land use impacts may
occur as a result of temporarily displaced activities, but these impacts are expected to
be minor and short-term in nature.
4.4 Wetlands
The proposed project will not have an effect on any wetland since field investigations
indicated that no wetlands exist on the project site.
4.5 Prime or Unique Agricultural Lands
The proposed project will not have an effect on any prime or unique agricultural
lands since these resources are not located within or near the project area.
4.6 Public Lands and Scenic, Recreational, and State
Natural Areas
The proposed project will not have an effect on any public lands and scenic,
recreational, and state natural areas since these resources are not located within or
near the project area.

Section 4
Environmental Consequences/Mitigation
4.7 Areas of Archaeological or Historical Value
Based on correspondence with the North Carolina Department of Cultural Resources
Division of Historical Resources (DHR), there are no locally designated sites of
historical or architectural importance in the general area of the project. Copy of
relevant correspondence with DHR is included in Exhibit B.
4.8 Air Quality
Construction of the force main will be associated with short-term, localized air quality
impacts such as increases in suspended particulate matter due to dust emissions from
the construction site and exhaust emissions from diesel and gasoline powered
equipment. Equipment exhaust emissions typically include nitrogen oxides,
hydrocarbons, carbon monoxide, and particulate matter. To control the amount of
dust that becomes airborne due to construction activities associated with the sewer
system improvements project, open construction areas will be sprayed lightly with
water. Discharges of vehicular airborne pollutants will be mitigated through the use
of proper emission control systems. No open burning will be allowed. No other
impacts to air quality are anticipated. The proposed sewer system improvements
project will not result in any significant long-term effects on air quality.
4.9 Noise Levels
Construction of the proposed sewer system improvements project will be associated
with a short-term noise impact due to operation of the construction equipment. In
order to minimize the noise -related disturbance to the local community, construction
activity will be limited to normal daytime hours (7 a.m. to 7 p.m., Monday through
Saturday) wherever possible. In addition, large construction equipment will be
equipped with proper noise attenuation devices such as mufflers and silencers to
minimize construction -related ambient noise level. Once construction of the sewer
system improvements project is completed, no long-term noise impacts will be
associated with its operation.
4.10 Water Resources
4.10.1 Surface Water
Impacts to surface waters will occur during construction of the stream crossings.
Streams will be temporarily diverted to install the force main. Once the area is
isolated, construction techniques across the streams will be similar to those used in
drier areas except that particular care will be taken to minimize the area of
disturbance. Types of stream crossings that may be used include cofferdams and
temporary stream diversions. The excavated stream sediments will be temporarily
stockpiled in upland locations set back from the stream banks. At the stream
crossings, the pipelines will be installed at angles as close to 90 degrees as possible.
After construction, disturbed stream banks will be restored to their original contours.
Rip rap will be placed below the high water stage, and stream banks above the high
water mark will be re -vegetated with woody plantings.

Section 4
Environmental Consequences/Mitigation
4.10.2 Groundwater
There will be no significant impacts to groundwater quality as a result of any of the
project components. None of the project components will result in a significant
disturbance to any water bearing strata, nor will any of the components involve a
groundwater discharge. By improving the existing sewer system and
reducing/eliminating SSOs, it can be assumed that groundwater quality along the
sewer force main will improve as no sanitary water ill escape the pipe. Anti -seep
collars will be provided upstream and downstream of stream crossings to control the
migration of water along the pipe bedding.
4.11 Forest Resources
Along most of the route, the sewer system improvements project will be installed
within or adjacent to existing roads, requiring minimal tree removal. At and adjacent
to the stream crossings, however, trees will be removed to construct and maintain the
sewer system improvements project.
4.12 Shellfish or Fish and Their Habitats
Construction of the sewer system project across the creeks and tributaries may result
in a short-term impact to the fishery resource and habitats in these areas. Every
reasonable effort will be made to minimize the extent of tree clearing required to
construct each phase of the project and to salvage merchantable trees that must be
removed. As soon as construction is completed in the streams, the turbidity levels are
expected to return quickly to baseline conditions. Fish species in the areas are
expected to return immediately while it may take somewhat longer for benthic
organisms to recolonize the areas. No long-term impacts to fishery resources or
habitats in the creeks, tributaries, or any other surface waters in the project vicinity
are expected as a result of this project. Specific guidelines outlining each of these
mitigation measures will be included in the construction specifications.
4.13 Wildlife and Natural Vegetation
The wildlife species and habitats associated with the pipeline corridor will be
temporarily disturbed or displaced. Because the areas that will be disturbed provide
relatively common habitat and no rare wildlife species are known to inhabit the area,
this short-term impact is not considered to be significant. Every effort will be made to
minimize disturbance in any forested area and to salvage trees.
4.14 Introduction of Toxic Substances
Construction and operation of the proposed sewer system improvements project will
not involve the use or discharge of any toxic substance.

Section 4
Environmental Consequences/Mitigation
4.15 Summary of Environmental
Consequences/IVlitigation
Table 4-1 summarizes the expected short- and long-term impacts associated with the
proposed East Side Sewer System improvements project based on the above
discussion. Construction of the proposed project will not result in any significant
short-term or long-term environmental impacts at or near the project area since the
pipeline will be installed entirely underground and within or adjacent to existing road
right-of-ways, which are maintained. During construction, some environmental
impacts may occur as a result of temporarily displaced activities, but these impacts
are expected to be minor and short-term in nature. Once the pipe is installed in the
trench, the trench will be backfilled and compacted, and the original contours will be
restored to the extent possible. No new buildings, parking spaces, pavement,
stormwater control devices, or other impermeable surfaces are included in this
project. Existing road pavement will be replaced where it is removed to install the
sewer.
Near the stream crossings, however, trees will be removed to construct and maintain
the sewers. The wildlife species and habitats associated with the pipeline corridor
will be temporarily disturbed or displaced. Because the areas that will be disturbed
provide relatively common habitat and no rare wildlife species are known to inhabit
the area, this short-term impact is not considered to be significant. Stabilization and
seeding of banks at stream crossings will occur immediately after construction (within
5 days). In no case will the top of the pipeline be less than 2 feet below the existing
tributary or stream bed. Anti -seep collars will be provided upstream and
downstream of stream crossings to control the migration of water along the pipe
bedding. The contractor will be responsible for removing any excess excavated
sediment from the site for disposal in a suitable upland location. A Sediment and
Erosion Control Plan has been developed for the proposed project and has been
approved by NCDENR.

Section 5
Secondary and Cumulative Impacts
Secondary and cumulative impacts of the proposed project are being mitigated by
proactive measures such as restoration of county floodplains and streams. The project
is being designed to increase capacity in the sewer system to minimize system
surcharging and overflows. This project will improve the water quality nearby creeks
by minimizing overflows from the sewer system.

Section 6
Environmental Justice
Identifying the size and location of low-income and minority population groups is an
important first step toward assessing whether or not the proposed East Side Sewer
System Improvements project disproportionately burdens or fails to meet the needs of
any segment of the population. The racial and ethnic and income -distribution patterns
provided by U.S. Census data sets were reviewed. The Census Bureau's latest county
level population estimates for 2008 - 2009 illustrate that the 2009 population of the
Union County is 198,645 with the 2008 composition illustrated in Table 6-1.

Non -Hispanic Whites make up slightly over 75 percent which is 8 percent above the
State's average. The second largest racial group is black which makes up 12.2 percent
of the population with the third largest racial group is Hispanic or Latino which
contributes 10.10 percent of the county's population. 8.6 percent of the population is
below poverty level.
Figure 6-1 provides a GIS map for a visual representation of the population
compositions that exist in proximity to the project area. The map reveals that
concentrations of White persons in the project area lower than the county's average
but still make up from 59 to 70 percent of the population. There is no evidence
showing the percentage of population below poverty level in this project area is more

Section 6
Environmental Justice
than that of the County's average. Based on the analysis with current available Census
data, it was believed that the proposed East Side Sewer System Improvements project
will have no effect on environmental justice. No disproportionate negative
environmental or health effects from the cumulative projects would occur on minority
or low-income populations.

Dear Mr. Huneycutt:
A review has been conducted of the Ula.ton County's self reported Sanitary Sewer
Overflows (SSOs) 5-Day Report(s) for .December 2009. This review has shown Union. County to
be in violation of the requirements found in Collection System Permit WQCS00054 and/or G.S.
143-215.1(a)(1). The violations that occurred during December 2009 are summarized in
Attachment A.
Remedial and cotTective actions, if not already implemented, should be taken to prevent
further SSOs. As of December 1, 2007, any reportable SSO may be issued a Notice of Violation
(NOV) and some may be assessed a civil penalty, Civil penalties will be issued for SSOs based
on. volume, volume reaching surface waters, duration and gravity, impacts to public health, fish
kills, and recreational area. closures. Other factors considered in determining the amount of the
civil penalty are the violator's history of spills, the cost of rectifying the damage, whether the
spill was intentional, and whether money was saved by non-compliance.

1.0 INTRODUCTION
House Bill 1160, the Clean Water Act of 1999, was ratified by the North
Carolina General Assembly on July 20, 1999 and signed into law by the
Governor on July 21, 1999. This legislation placed significant reporting
requirements on entities that own or operate wastewater systems. This
Performance Summary is intended to establish compliance with this rule.
Union County Public Works (UCPW) is charged with the management,
operation and maintenance of the County's sanitary sewer system.
During the 2014-15 fiscal year the wastewater system was comprised of 5
active wastewater treatment plants (WWTP), approximately 67
wastewater pumping stations, and over 635 miles of pipe with 33,047
connections. In addition to the 5 WWTPs which have a combined rated
treatment capacity of 8.15 million gallons per day (MGD), the County,
through contractual agreement, has 2.65 MGD and 3.0 MGD of purchased
capacity at the City of Monroe WWTP and Charlotte's McAlpine Creek
WWTP respectively.
Public Works' Mission Statement is as follows:
Develop water, sewer and solid waste infrastructure that supports
residential, commercial, industrial and agricultural needs while meeting
Federal/State regulations and providing our customer base with
acceptable levels of service at cost effective rates
2.0 DEFINITIONS
For the purposes of this Performance Report the following definitions apply:
• Aerobic — A condition in which atmospheric or dissolved molecular
oxygen is present in the aquatic environment.
• Automatic Telephone Dialer or ATD — A device connected to the
telephone system that will call programmed telephone numbers to alert
people of equipment status.
• Biological Nutrient removal — The process of removing nitrogen and
phosphorus from wastewater using biological processes as opposed to
chemical means.
• Biosolids — A primarily organic solid product, produced by wastewater
treatment processes that can be beneficially recycled. The word
biosolids replaces the word sludge.
• BOD — Biochemical Oxygen Demand — The rate at which organisms
use the oxygen in water or wastewater while stabilizing decomposable
organic matter under aerobic conditions. The BOD Test is a procedure
that measures the rate of oxygen use under controlled conditions of
Union County Wastewater

time and temperature. BOD is typically used to express the "strength"
of wastewater.
• CL2— Chlorine Residual — The amount of chlorine present in the final
effluent after disinfection. Typically measured in micrograms per liter
or milligrams per liter.
• D.O. — Dissolved Oxygen — Molecular (atmospheric) oxygen
dissolved in a liquid.
• Effluent — Treated wastewater flowing from the treatment system.
• Extended Aeration — A type of wastewater treatment facility in which
the wastewater is retained and treated for a minimum of 24 hours at
design flow before discharge occurs.
• Impeller- A rotating set of vanes in a pump designed to pump or lift
water.
• Inflow and Infiltration (I&I) - extraneous water that enters the sanitary
sewer system through openings and/or defects in the collection
system.
• Fecal Coliform — The coliform (bacteria) found in the feces of warm
blooded animals. The presence of coliform-group bacteria is an
indication of possible pathogenic bacterial contamination.
• MGD — Million Gallons per Day — Volumetric measurement of flow
converted to millions. Example 150,000 gallons per day (gpd) /
1,000,000 = 0.150 MGD.
• NH3— Nitrogen as Ammonia —A compound found naturally in
wastewater. The compound is produced by the deamination of organic
nitrogen containing compounds.
• NPDES Permit — National Pollutant Discharge Elimination System
- Permits, required by the Federal Water Pollution Control Act
Amendments of 1972, which regulate discharges to surface waters.
• pH — The expression of the intensity of the basic or acidic condition of
a liquid.
• Pump Station — A holding tank with pumps that forces wastewater
uphill when flow by gravity is not possible.
• Reclaimed Water — Highly treated wastewater that has undergone
advanced treatment processes to remove solids, organics, and
pathogens meeting the State's Health and Safety Standards for
Beneficial Reuse.
• SCADA — Acronym for "supervisory control and data acquisition';
a computer system for gathering and analyzing real-time data.
• SBR — Sequencing Batch Reactor — A type of wastewater treatment
facility that treats and discharges water in batches as opposed to
continuous flow.
• SSO — Acronym for "sanitary sewer overflow"
• Telemetry — A system by which information pertaining to remote
equipment status is transmitted via radio waves to a central location.
• TSS — Total Suspended Solids — Particles suspended in a liquid.

• Turbidity — The measurement of the clearness or cloudiness of a
liquid.
3.0 SYNOPSIS OF WASTEWATER TREATMENT FACILITIES
(Fiscal Year 2014-2015)
During the 2014-15 fiscal year the Department of Public Works operated
and maintained a total of five (5) active wastewater treatment facilities and
maintained one (1) inactive facility. Although each Permit requires facility
visitation daily, excluding weekends and holidays, Public Works'
wastewater treatment facilities are checked 7 days per week, 365 days
per year. All treatment facilities are equipped with emergency back-up
power generators. In addition to SCADA, each facility has both audible
and visual trouble alarms. Wastewater treatment plant staff rotate "call
duty" for after hour situations that may arise.
A brief overview of each facility and a performance summary table for
each facility is provided herein.
3.1 Twelve Mile Creek Water Reclamation Facility
Permit No. NC0085359. Twelve Mile is an extended aeration facility
utilizing biological nutrient removal and tertiary filtration. Disinfection is
accomplished via UV (ultraviolet Tight). Twelve Mile effluent is discharged
into Twelve Mile Creek, which is part of the Catawba River Basin. The
facility is permitted to discharge up to 6.0 MGD of treated wastewater.
Twelve Mile Creek WWTP is located at 8299 Kensington Drive and serves
Waxhaw as well as portions of Indian Trail, Stallings and Weddington.
Please refer to Table 3-1.
3.2 Crooked Creek Water Reclamation Facility
Permit No. NC0069841. Crooked Creek is an extended aeration facility
utilizing tertiary filtration. Disinfection is accomplished via UV (ultraviolet

4.0 BIOSOLIDS MANAGEMENT
Biosolids are managed and disposed of in accordance with Permit No.
WQ0007486 issued by the North Carolina Department of Environment and
Natural Resources. Biosolids are stored at both the Crooked Creek and
Twelve Mile Creek WWTPs. The solids are aerobically digested and then
applied as "fertilizer" to permitted sites. The solids are considered stabilized
and thus suitable for land application when the volatile solids content is
reduced by 38%. If this 38% volatile solids reduction can not be achieved,
then alkaline stabilization, injection or incorporation is employed to insure
permit compliance. Union County Public Works, through its biosolids
contractor, land applied approximately 6 million gallons of biosolids.
5.0 SYNOPSIS OF WASTEWATER COLLECTION SYSTEM
(Fiscal Year 2014-2015)
Permit No. WQCS00054. UCPW currently operates and maintains over 635
linear miles of sewer mains, including force mains, and 67 wastewater
pumping stations providing service to population of approximately 95,836
customers (33,047 wastewater accounts x an average of 2.90 people per
account). All pump stations are equipped with both audible and visual alarms
as well as either automated telephone dialers (ATD) or telemetry which alert
staff when alarm conditions are present. Inspections of all pump stations meet
or exceed State requirements. Emergency auxiliary power is provided to all
stations via portable or permanent mounted generators. Union County
personnel are on call rotation and available 24 hours a day, 7 days a week,
and 365 days a year.
Public Works is required by State permit to clean a minimum of 10% of the
collection system annually to prevent and/or reduce backups and overflows.
Staff has consistently surpassed that requirement, cleaning more than the
required 10%. UCPW cleaned approximately 14.2% (80 miles of 563 total
gravity miles) of the collection system last year. Staff also conducts
inspections of the collection system with the utilization of underground closed-
circuit television (CCTV) inspection equipment. These cleaning and inspection
efforts allow staff to determine areas in the system that require repairs or
increased maintenance to provide the proper service to our customers.
FOG (Fats, Oils, and Grease) program is aimed at reducing grease -related
back-ups and overflows by educating the public of the hazards associated with
the disposal of grease and grease related by-products into the wastewater
system. Union County Public Works, in conjunction with Union County
Environmental Health, has developed a comprehensive list of food service
establishments and commercial establishments. This effort will assist in
development and enforcement of a grease trap inspection program ensuring
Union County Wastewater System

Utility easements and right-of-ways are maintained by UCPW staff to ensure
access for staff and equipment to conduct routine maintenance as well as
respond to emergencies, such as sanitary sewer overflows. The easements
require round-the-clock access and should not be impeded by structures such
as pools (above or below ground), buildings, etc. as well as gardens, trees,
shrubs, plantings, etc. Public Works staff inspects and conducts necessary
maintenance, including mowing, to these easements and right-of-ways once a
year, at a minimum.
High priority lines such as aerial creek crossings, lines subject to erosion
and/or problematic areas are visually inspected at a minimum semi-annually.
High priority lines are inspected more frequently after periods of heavy rain
and flooding.
UCPW maintains emergency response equipment in a ready state at all times.
This emergency equipment varies in nature from spare electrical parts and
plumbing supplies, to vacuum trucks, pumps, and backhoes. Workers safety
is of utmost importance. Safety equipment such as night lighting, gas
monitors, trenching and shoring equipment, and reflective cones/signs are
always readily available.
UCPW has Capital Improvement Projects (CIP) to identify and correct
deficiencies associated within the wastewater collection system.
❖ Grassy Branch and Twelve Mile Creek Manhole Rehabilitation
project began in January 2014. The project will reduce storm water
entry (inflow & infiltration — "I&I) into the sanitary sewer system reducing
increased treatment and maintenance costs. This project is a part of a
comprehensive "rehabilitation and repair" program in the Public Works'
CIP plan to conduct necessary repairs to the collection system on an
annual basis. YTD approximately $225,000 has been spent on
rehabilitation efforts to over 215 manholes.

Helmsville Road Pump Station upgrade project began its design
phase in early 2015. The anticipated start date for construction is
December 2015, with project completion estimated in May 2016. This
project consists of a new, larger wet well, new pumps, generator, and
control equipment.
Community Park Pump Station rehabilitation project began its design
phase in late 2014. This project is to completely rebuild the Community
Park pump station due to age and material concerns, as well as site
accessibility.
❖ Ongoing sanitary sewer evaluation studies (SSES) throughout the
collection system to identify problems and need for rehabilitation.
During the Fiscal Year 2014-2015, Union County's wastewater system
collected and conveyed approximately 3.05 billion gallons of wastewater.
There were sixteen (16) sanitary sewer overflows with a combined estimated
volume of 76,520 gallons that occurred within the collection system. Union
County Public Works conveyed 99.998% of the total volume of wastewater
without incident.

Per 15A NCAC 2H .0220, the Division received a final engineering certification for the subject project on
5/ 11 /2006. Enclosed is a copy of the certification page for your records. A full review of the certification
materials may or may not be conducted. It is assumed that receipt of this certification indicates compliance
with all regulations, design criteria and the permit. However, if a full technical review is conducted, you will be
notified of any items of non-compliance. Note that the Division does not acknowledge partial certifications
by letter. It is the Permittee's responsibility to track all submissions and receipt of partial certifications to the
Division.
Please be reminded that the Permittee is responsible for keeping a copy of the final record drawings for the
life of the project. If you have not received such copy from your consultant, please contact them
immediately to obtain a copy.
Lastly, you are receiving this letter because the Division has you listed as the responsible party. If this permitted
system is no longer owned by you or your company, please complete Form PNOCF-S as this permit is not
automatically transferable. Form PNOCF-S can be downloaded from http://h2o.enr.state.nc.us/percs from
the Collection Systems Applications page.

Please find attached the supporting materials that respond to your May 12, 2006 email relating
to the referenced `project submittal. Materials included are: .
1. Design calculations (determination of flow, hydraulic calculations, pipe velocity)
2. System curve
3. Cycle 'time and run time. calculations
4. Pump curve and pump data (Fairbanks Morse 4" 5433 MV)
5. Buoyancy calculation .
To avoid confusion, please discard previous supporting documents. These are more
thorough, connect the information together better, and incorporate the most recent field
observations, calculations and product deliverables.
You had previously posed a question relating to solids accumulation and flushing ability. The
force main includes five (5) combination air/vacuum release valves. These are primarily to
relieve potential hydraulic problems, but also provide some limited remedy to solids settling. At
each of these locations, two valves may be closed, the combination air/vacuum release valve
may be removed, and a pumper truck may be connected to induce high velocity flushing. Minor
pipeline modification at these locations would also facilitate pigging or jet -vac flushing; however
the lift station would have to be offline to allow this. Additional flushing can also be achieved by
connecting a portable pump at the bypass pumping connection located in the valve vault.
Union County is already considering construction of the sewer extension to connect the Fairfield
Plantation. subdivision and take the Goose Creek Utilities WWTP offline. The engineering sheet
depicting this section has been corrected and is attached herewith.

the lower seal uses carbon against ceramic
faces as standard. The lower seal also incor-
porates a protective cup to prevent trash, grit,
or stringy material from interfering with the
mechanical seal Optional silicon carbide
against tungsten carbide seal faces are also
available to provide added assurance of prod-
uct reliability.
STAINLESS STEEL BOLTING
External bolting is stainless steel 'as standard
for ease of maintenance.
IMPELLER
Solids -handling enclosed radial flow, two -
vane, or bladeless design, having blunt well
rounded leading edges and thick hydrofoil
shape to pass large solids and stnngy material.
One-piece cast impellers are designed for cir-
cular flow and matched to the equalizing -cores -
sure. constant -velocity thick well volute.
Impeller is trimmed to meet conditions of Oper-
ation.
WEAR RINGS
Impeller and volute may be fitted with axial
wear nngs of hardened 300-350 Bhn or higher
stainless steel.

SOLIDS PASSING
Sphencal solids which pass through the impeller
and volute passageways can also pass between
the volute cutwater and a full diameter Impeller.
PULL-UP SYSTEM
Two rails mounted on the discharge base/elbow
provide a guide to the pump when raised or
lowered in the sump
THERMOSTATS
Imbedded in the motor windings to protect from
overheating. These devices are reset automati-
cally. Excessive heat will cause the normally
closed contact to open, stopping the motor
BEARING LIFE
Oil lubricated thrust bearing and radial bearing
with an L10 bearing life of 50.000 hours at BEP
For higher bearing load applications, optional
bearing construction is available
TWO MOISTURE DETECTORS
Detect moisture entenng the oil cavity or stator
housing and send a signal to a compatible con-
troller.
OIL INSPECTION PLUGS
Cdnvenienl. removable 0-ring sealed plugs for
Inspection and ease of changing oil in the
mechanical seal chamber
DISCHARGE BASE/ELBOW
Rigid, heavy-duty cast iron, with 125 lb. ANSI
flange supports the total weight of the pumping
unit .
SLIDING BRACKET ASSEMBLY
Non -sparking, UL Listed explosion•proof
bronze Constructed so when lowered onto the
discharge base/elbow. a knifing action of the
vertical metal -to -metal. self-cleaning non -clog-
ging connection is secured.

To: Jay Johnston <[e-mail]>
Hi Jay,
I received your certification yesterday. A few comments...
til [5 S/Ci1 o) (L,[CS
I saw your cover letter note but please realize that the rules allow a reduced
wastewater flow rate with approval from the Division per 15A NCAC 2H .0219(1)(3).
Union County does not have an approved flow reduction and so the design should not
have been based on actual flows without obtaining a flow reduction from the Division.
Your pump station calculations should include everything We would want to see up
front had a full technical review been conducted prior to permitting. This will include
the following: friction/total dynamic head calculations and system curve analysis (with
one pump running, two pumps running, etc.); pump selection information including
pump curves, manufacturer's information, pump station cycle times and pump run
times; minimum velocities in the sewer extension in accordance with 15A NCAC 2H
.0219(i) (2) (B); and flotation calculations for the pump station. The items in red seem to
be missing. Additionally, will the force main remain full or will there be gaps between
pumping cycles where solids will settle. If so, does the line have flushing capability?
Tell me about the future 8-inch sewer at .19% between MH 16 and MH 17 and the future
10-inch sewer at .2% between MH 17 and MH 18.
Thanks,
Marie

3.0 FLOW ESTIMATES AND PROJECTIONS FOR DESIGN
It would be relatively simple to design a new lift station to handle the current
wastewater flow at the Hunley Creek WWTP. The daily monitoring reports (DMRs)
provide all of the flow data needed to size the proposed systems.
However, planning the proposed systems in this manner is impractical since the
possibility exists to : bring flow from Fairfield Plantation WWTP, not to mention the
potential for growth in both the Hunley Creek and Fairfield Plantation sub -basins. The
following sections summarize our design flow,estimates:for the_proposedsystems.
3.1 Hunley Creek Sub -Basin
This sub -basin includes both the Hunley Creek and Shannamara subdivisions.
Based on information provided by Union County, the maximum number of lots
available for residential construction is 1187. Since zoning does not permit
commercial development here, build -out in this sub -basin is 1187 houses.
Estimate},using: State standardsf, There are currently approximately 800 homes
in the sub -basin. Using the standards set forth in 15A NCAC 2H .0200 — Waste not
Discharged to Surface Waters, the current and build -out average daily flows (ADF)
can be estimated as follows:
Current ADF
800 houses x 3 bedrooms/house x 120 gpd/bedroom = 0.288 mgd
Build -out ADF
1187 houses x 3 bedrooms/house x 120 gpd/bedroom =' 0 427 mgd•:
Build -out Peak Flow (Design Flow)
0.427 x 2.5 = 1.07 mgd
(the State requires 2.5 peak factor for design in the absence of actual flow data)
Estimate using .existirig:Ydata'iThe same State code referenced above allows for
sizingsystems using existing data, such as that provided in the in the Daily
Monitoring Reports (DMRs). An analysis of Hunley Creek's DrvRRs for the previous
year and a half indicates the average daily flow at the plant is approximately 0.150
mgd. The peak flow rate observed during this period was 0.322 mgd. Using the data
from the DMRs and our knowledge of existing customers, we calculated the peak
factor and build -out flow as follows:
ADF observed = 0.150 mgd
Peak flow observed = 0.322 mgd
Peak Factor
0.322 = 0.150 = 2.15*
Union County Wastewater Diversion Project Page 4 of 17

Houses generating flow = 800 houses
. Average flow. per house
0.150 mgd - 800 houses = 187.5 gpd/house
• (round to 200 gpd/house)
Build -out ADF
1187 houses x 200 gpd/house =0 237= mgd
Build -out Peak Flow (Design Flow)
0.237, mgd x . 2.15. = 0.510 mgd .¢--U$a-FrnR 131i p
'GT?ott./
(* data -supported peak factor based on actual flow data)
Hydrostructures, P.A. recommends using this latter set of calculations for
design for two primary reasons: they are lower so the project can be sized more
modestly and they are supported by actual data. Since these calculations are based on
total flow data, no additional consideration need be added for inflow and infiltration.
3.2 Fairfield Plantation Sub -Basin
The current Fairfield Plantation layout includes 197 existing houses and an
additional 40 platted lots. The developer owns approximately 120, acres adjoining
the Fairfield Plantation development. Based on descriptions provided by the
developer; the additional acreage will be approximately half single family residential
and half commercial (office park). Therefore, we estimate that the additional acreage
will produce approximately 100 new single family dwellings and, 50 to 60 acres of
office park. Using various examples of commercial development, we estimated that
a maximum of 1800 employees (or an equivalent) for the commercial development.
Estimate using:State;standci ds As above, using the standards set forth in 15A
NCAC 2H .0200 — Waste not Discharged to Surface Waters, the current and build -
out wastewaterflows can be estimated as follows:
Current ADF
existing: 197 houses x 3 bedrooms/house x 120 gpd/bedroom
Build -out ADF
existing: 197 houses x 3 bedrooms/house x 120 gpd/bedroom
platted: 40 houses x 3 bedrooms/house x 120 gpd/bedroom
future: 100 houses x 3 bedrooms/house x 120 gpd/bedroom
future: 1800 employees x 25 gpd/employee
= 0.071 mgd
= 0.071 mgd
= 0.014 mgd
= 0.036 mgd
0.045 mgd

Page 5 of 17

Build -out Peak Flow (Design Flow)
0.166 mgd x 2.5 = 0.415 mgd
(with State -required 2.5 peak factor for design)
Estimate using existingdta: As with the Hunley Creek WWTP, the Fairfield
Plantation WWTP is required to maintain DMRs. The DMRs can be used to predict
future flows using actual data. An analysis of Fairfield Plantation's DMRs for the
previous two years indicated that the average daily flow (ADF) at the plant is
approximately 0.063 mgd. The peak flow rate observed during this period was
approximately 0.150 mgd (throwing out several anomalously high peaks). Using the
available data and the existing house count, we calculated the build -out flows as
follows:
Average Daily Flow = 0.063 mgd
Peak flow observed = 0.150 mgd
Peak factor = 0.150 T 0.063 = 2.4
Houses generating flow = 197 houses
Average flow per house
0.063 mgd - 197 houses = 320 gpd/house
Build -out ADF
337 houses x 320 gpd/house - $0.108.,mgd
Peak daily flow
0.108 mgd x 2.4 = 0.259 mgd —` Cl0"i4 Ririe
$tEe.F.cf<v<V
The higher unit flow rate (gpd per house) is likely due to a larger percentage of
inflow and infiltration in the Fairfield Plantation collection system. Including this
factor when estimating the future flows adds a small safety factor in design
calculations. As with Hunley Creek, Hydrostructures, P.A. recommends using the.
flow estimates derived from actual data.
The table below summarizes our discussion on calculating wastewater flows.
As stated, we recommend using the flow estimates derived from actual data;
therefore, only those flows calculated from real data appear in the table below.
Another key piece of data shown in the table below is the percentage of the total
combined flow belonging to Fairfield Plantation. This figure helps to illustrate that
Fairfield Plantation uses a measurable percentage of the capacity throughout the
proposed infrastructure upgrades. This will be discussed in greater detail in.
following sections.

Dear DWQ:
Please find attached the Engineer's Certification and supporting materials for the referenced
project.
PLEASE NOTE: Sizing. for._the;sewer:pump.station islt ased on'a 2002 Engineering'Study of the
.basin Build -out flow for the basin is difficult to pinpoint in the dynamic Union County
environment. • We have attempted to -hit a middle ground point in pump sizing while providing
ample. provisions for potential flow increases above what was predicted in the study. The pump
station internal piping is configured such that higher flow pumps can be simply installed should
they be necessary.
After our initial submittal of the Fast Track Application, we received comments from DWQ in a
January 28, 2003 letter. These comments were incorporated in a resubmitted FTA along with
supporting documentation. However, theimiddIe ground tityp.oint forthe pump was'mistakenly
0ot`amended ":The duty,point is',600 gpm@ 111 TDHy(see attached documentation). This duty
point hits between the peak flow conditions observed in 2002 and the projected basin peak flow
conditions based on the engineer's calculations. J3asin peak7flow:conditiions:using:DV11Q
prescribed unitflow rates may be higher; -,but, as;_stated above;.the-,station; was.: constructed:to:
allowflow'expansionywhen. the need "arises .
Should you have any questions regarding this certification, please call me at 542-5002, ext. 3#.
Sincerely,

Subject: Project Return
Union County
Wastewater Collection System Extension
Union County .
This letter is in reference to the request for several non -discharge permits (sewer extensions) to
serve the following projects received as listed in the table below are hereby returned. In accordance
with North Carolina Administrative Code 15A 2T .0304 (b) the Division has determined that based
on requested information provided in your March 13, 2007 letter the treatment system is not
capable of accepting the additional waste represented in this permit applications. This is evidenced
by flow limit violations that you have reported for the Twelve Mile Creek Wastewater Treatment .
plant (NC0085359). Further, this decision is based on sanitary sewer, overflows at the influent
structure of the Twelve Mile Creek WWTP and associated collection system despite the relatively
dry weather. The increased flows that would be allowed by these permits, if granted, would serve
only to worsen the frequency and severity of violations and could potentially lead to health and
environmental impacts.

Sewer permits rejected in Union Co.
JULIA OLIVER
Warning that an overload at Union County's biggest sewer plant could cause health and environmental problems,
the state on Thursday rejected sewer permits for more than 1,000 homes.
The state's action also stops plans for construction of a Lowe's in Waxhaw, part of a shopping center in Wesley
Chapel and two medical centers.
Union County has not been able to expand its sewer system fast enough to meet growth -driven demand. It's the
15th-fastest- growing county in the nation and first in North Carolina, according to Census Bureau data released
this week. Since 2000, Its population has increased 42 percent and it's growing at a faster rate each year — all of
which means more and more waste.
Susan Massengale, a spokeswoman for the N.C. Division of Water Quality. said the state rejected the permits
because Union's sewer system is already overburdened. It can't process all the waste it gets now, and untreated
sewage has been released Into Twelve Mile Creek.
The state said the county could reapply for the permits when the Twelve Mile Creek plant is expanded. That work
is expected to be complete by late summer.
Massengale said the state doesn't usually take such action, but Union had not shown it could handle more
development.
'They've gotten caught up in this incredible rate of growth," she said, "and it's just overwhelmed their system."
Union County's inability to keep up with growth has led to state sanctions at its biggest sewage treatment plant,
the Twelve Mile Creek facility. Last month, the state stopped issuing permits for development served by the plant
because it was overflowing regularly. In addition, the state has fined the county about $100,000 over the past
three years for discharging insufficiently treated sewage Into the creek.
Public Works Director Christie Putnam did not retum a phone call Thursday night.
Though the county must approve sewer applications, the state has final say over what projects get permits.
Those rejected Thursday included about 20 developments. Among them were at least two commercial projects —
a Lowe's in Waxhaw and the Village Commons at Wesley Chapel — and two medical facilities: an emergency
medical center being built by Carolinas Medical Center -Union in Waxhaw, and Waxhaw Medical Center.
The state rejected the permits in a letter Thursday.
•
'The Increased flows that would be allowed by these permits, if granted, would serve only to worsen the
frequency and severity of violations and could potentially lead to health and environmental impacts," it said.
According to county data sent to the state, the Twelve Mile Creek plant regularly overflowed its allowed capacity
from November through February. In January, the plant's average flow was almost a million gallons over what it
was supposed to be.
Developers with rejected projects said they were surprised, but many declined to comment.
Sean Calloway, Charlotte development manager for G.S. Carolina, said the decision would slow the sale of 50
lots at the Cureton subdivision. He said it could affect scheduled road improvements by his company. 'That's
really bad news," he said.

Mr. John Lesley
Acting Surface Water Protection Regional Supervisor
610 East Center Ave Suite 301
Mooresville, NC 28115
Subject: Response to Requested Information
Dear Mr. Lesley,
In response to your requests for additional information dated March 6, 2007, Union
County Public Works (UCPW) hereby submits the following response.
1. The 12 Mile Creek Waste Water Treatment Plant (12 Mile) has exceeded its
permit limit for flow. However, we have received the additional permit page to
operate at 3.0 MGD upon comr I .ion of our Phase I expansion. This phase I
expansion includes increasect influent pumping capabilities, a new MLSS
distribution box, larger clarifiers, a new RAS station with clarifier specific flow
control, an additional 1.0 MG digester, a new. WAS station and standby power.
We have also received a verbal commitment from. Cecil Madden -with -
Construction Grants and Loans that upon completion we will be given an
authorization to operate at the ne_ w hermit limit. Installation of equipment is
nearing completion and start up of new facilities has already begun. Phase I is,
expected to be complete in the next two weeks.
k1
Additionally, to maintain compliance with defined parameters in our NPDES
permit we have instituted the following measures:
a. Added additional horsepower to our aeration basins, August 2006/
b. Added additional staffing, summer 20061/
c. Added enhanced chemical feed facilities, summer 2006
d. Expanded testing abilities for phosphorous monitoring, summer 2006
These improvements have allowed us to consistently meet the nutrient limits
defined in our NPDES permit for 6 MGD, which are more stringent than our -
current defined limits.
2. Provided is a table of average monthly flows and new customers per month for
the previous 12 months for 12 Mile.

3. Sanitary sewer overflows are a serious concern to UCPW. Wehave contracted for 6,34
-ai ?
inspection of every manhole in our system. UCPW has used flow monitoring and 1,0 Le/Le,
smoke testing to identify areas of increased levels of I/I to focus rehabilitation
efforts. Inspection reports are generated identifying and prioritizing necessary
repairs. Our I/I crew then uses this report to define the daily repair schedule. In
2006 almost 1500 point repairs were completed for an estimated 420 gpm• 00,Oc7 f
reduction of I/I into our collection system. (p C
( dw Additionally, we have modified our specifications and require vacuum testing and
1 video of all laterals to ensure proper installation and prevention of future sources
of I/I into our collection system.
-1694142
As previously discussed an increase in pumping capacity at the influent pump
station for 12 Mile should be activated in the agg_femuNeeks. UCPW is confident
this will relieve the back of flow currently experienced into the pump station
alleviating the cause of the reoccurring SSOs at the headworks of the treatment
plant.
UCPW recognizes your concerns relating to SSOs and submits that the majority
of the permits currently submitted for consideration will not result in additional
flow until after the 12 Mile expansion to 6.0 MGD is complete. This in conjunction
with the rehabilitation effort described above indicates these proposed permits
will not contribute to an increase in number and magnitude of overflows. _
4. Currently UCPW contributes approximate) 700,000 g t e McAlpine
Treatment Plant (McAlpine). We have a con ariotte-Mecklenburg
Utilities for 3.0 MGD of treatment capacity. Tw pump stations, Tarkill and
Millbridge have been identified to transfer flow from 12 Mile to McAlpine. The
current flow permitted into the Tarkill pump station is 337,000 cord. The current
permitted flow into the Millbridge pump station is 60,000 god. Flow meters are
being installed at both pump stations to provide a.ctuaLflowinformation. The
infrastructure to enable the diversion of the Tarkill pump station is expected to
be completed within the next month. The Millbridge diversion permit is
forthcoming. UCPW will submit the permit modifications to reallocate flow from
12 Mile to McAlpine for the existing permits in the Tarkill basin. This will allow for
the diversion of approximately 337,000 gpd prior to realizing any flow from the
permits currently submitted for consideration.
5. The collection system is used for tos is practicable. We currently store
water in the interceptor to the maximum extent possible while avoidi
overflows. UCPW does not see shard peeks in flow, but rather realizes a

significant increase hours after a storm has passed. This increased is sustained
over a number of days. Due to the duration of high flows, storage in the -
tributary system is not practical.
Due to the number and location of pump stations, automated controls would be
needed to effectively manage flow to enable the use contributing systems for
flow storage. Often, these tributary systems themselves are operating near
capaci using available storage opportunities.
UCPW acknowledges the concerns addressed by this request. We do not expect flow
from the majority of the submitted permits under consideration to exceed the
anticipated treatment expansion schedule. This in concert with the upgrades at 12 Mile
and the timing of the diversion of the Tarkill and Millbridge pump stations will reduce
the effects of issuance of these permits on our existing flow limitations. Therefore,
based upon the information provided, UCPW request issuance of the outstanding
permits. If you have any questions, please do not hesitate to call
Sincerely,

Re: Twelve -Mile WVVI P NPDES NCO() 35360
On Friday June 16,2006 I made a site visit to the Union County Twelve Mile WVVTP to investigate odor
complaints. I arrived on site at 7:30 am and was accompanied by Mark Tye and Charles McCoy from
Union County staff. Construction has begun on site to expand the plant capacity to 6 MGD. One of
the tanks reported as leaking by residents of the Quenlin subdivision is a new digester tank still under
construction. I walked around the influent pump station and the outfall line under the Cureton Parkway
Bridge. No odors were detected that morning. On 6/15/2006 150 #s of NaOH had been added to the
Tar Kill pump station. Drove over the parkway bridge into Quenlin subdivision and down Thayer Drive,
and no odors were detected.
The bar screen area of the VWVTP had a detectable odor when standing on the grating but not at
ground level. The aeration basin (carrousel) had no detectable odors when standing on the walkway
between the ditches. New aerators were started that moming to observe any odors that may be
generated from this area, and none were detected. On the digester walkway there is a direct view to
the houses that are located on Thayer Drive in Quenlinand back up to a tributary of East Fork Twelve
Mile Creek. During construction of the connecting roadway trees bordering the Twelve Mile Creek
WVVTP property were cut down. It is possible that odors from these units now travel to the valley and
have caused some of the more recent complaints. One of the tertiary filters was out of service for
repairs to be made to the concrete.
From the observations made on the morning of 6/16/06 the VVVVfP was being properly operated and
no obnoxious odors were being emitted from the process units of the facility.

Union sewer expansion nixed
JULIA OLIVER
The state has denied Union County's request to expand its biggest and most strained sewer plant, a
decision that surprised county officials and could slow development in the states fastest -growing
county.
In denying the permit, the N.C. Division of Water Quality said that Twelve Mile Creek, where the
plant discharges, can't take any more sewage.
"It's huge," said commissioner Parker Mills. "We're going to really have to regroup."
The plant is scheduled to be expanded to a capacity of 6 million gallons per day this summer, but
Union had asked the state for a second expansion — to between 9 million and 15 million gallons per
day. The state denied that expansion, according to a county news release sent Tuesday evening.
The decision is the latest in a series of sanctions related to the plant, which has frequently
overflowed and failed to treat sewage to state standards.
In February, the state stopped issuing permits for development in the Twelve Mile Creek service
area until the current expansion is finished. It also rejected permits for several projects — including a
Lowe's Home Improvement, two medical centers and about 1,000 homes.
County Public Works Director Christie Putnam could not be reached Tuesday night.
The speed of development in westem Union has overwhelmed county planning. Putnam has
estimated that even after the current expansion is complete, developers will be waiting in line for
sewer pemlits.
In the meantime, the county is exploring ways to alleviate pressure on the plant — by diverting
sewage to Mecklenburg County, for example, or by using highly treated sewage for irrigation so it
does not discharge directly into the creek.
Commissioners had pushed to expand the plant as much as possible. The denial shocked them.
Commissioner Allan Baucom said a sewer shortage could impact not only developers and builders,
but also people who have bought homes in incomplete subdivisions.
'This can have long arms as far as affecting lots and lots of people in the county," he said.

FROM: Union County Public Works
SUBJECT: Wastewater Spill
Beginning Friday February 18, 2000 at 9:30 a.m. and lasting until 6:30 p.m. on
the same date, approximately 18,900 gallons of untreated wastewater entered
New Salem Branch. The wastewater spilled from a manhole located near Union
County Public Works' Wastewater Pumping Station #3, off NC Hwy 205. The
spill was the result of an internal pump failure. The failure prohibited the pump
from discharging it's rated capacity. A second pump located at the station
automatically started but was unable to keep up with high flows attributable to
heavy rains in the area. The failed pump was promptly replaced with a spare
pump that is kept on site. Upon activation of the new pump the spill ended.
Stream samples taken during the spill indicated minimal environmental impact.

SUBJECT: Wastewater Spill
At approximately 10:00 a.m , g;;tt a ; ,00N-during routine inspection, Public Works
Staff discovered wastewater spilling from a pump station located off Sharon Drive in
Waxhaw. The cause of the spill was determined to be low incoming voltage. The pump
station control panel has a device (referred to as a "phase monitor") that is designed to
effectively shutdown the pump controls during periods of high or low voltage. The
purpose of the device is to prevent permanent motor damage from inappropriate voltage.
Staff was able to lower the voltage setting on the phase monitor and restore control
power. The process of trouble shooting the panel and making the adjustment took
approximately 20 minutes.
The pump station is equipped with an Automated Telephone Dialer (ATD) alarm system.
However, the ATD was set-up to alarm only during a complete power outage. Staff has
since installed the necessary components to generate an alarm once the liquid level in the
pump station reaches a predetermined level.
Based on equipment run time, it is estimated that;28,00,C all h:ssf wastewater entered
ar�.e l3reh rrThe spill depleted dissolved oxygen levels in the creek resulting in a fish
kilt. 30 fish of varying size and species were netted from the creek and disposed of The
area around the pump station was remediated and limed.
Union County Emergency Management, the NC Wildlife Resources Commission and the
NC Division of Water Quality were notified.

SUBJECT: Wastewater Spill
At approximately 5:00 p.m on F ar 3u :e -I6;. 2000-the Public Works Department
received a report of a possible wastewater spill. Personnel were immediately dispatched
to the Brittany Downs East subdivision off Sardis Church Road in Indian Trail. Upon
personnel arrival, a surcharging manhole was discovered. The wastewater was flowing
approximately 250 yards through a drainage ditch and into the South Fork of Crooked
Creek. According to neighborhood homeowners, the wastewater had been spilling since
,,Mandayitune 1.2, 2000 Based on the best available information it is estimated that
604:009 gallon spy+l9l the-tna, ority of which entered the South Fork of Crooked Creek.
The spill caused a depletion of dissolved oxygen in the creek resulting in a fish kill.
Fourteen fish were recovered from the effected area. Stream monitoring data collected
the day of the spill indicated that approxniately two miles of the creek were iinpacted.
Stream monitoring data collected the following day ( Saturday June 17th) showed
dissolved oxygen concentrations approaching normal levels.
The spill was caused by a mechanical sewer plug This type of plug is typically used to
block flow in sewer lines during periods of repair, construction and/or maintenance. The
origin of the plug in this situation is unknown at present. County management is treating
the incident as vandalism. A Sheriffs report has been filed.
After initial assessment of the spill by County personnel corrective measures were
implemented within a l0-minute time frame. Cleanup measures included removing the
plug, "vacuuming" approximately 9000 gallons of sewage from the drainage ditch,
spreading lime over the affected area and netting fish from the creek.
The Division of Water Quality was notified Friday evening.

EXECUTIVE SUMMARY
FLOW MONITORING AND CAPACITY ANALYSIS
EASTSIDE SEWER COLLECTION SYSTEM
UNION COUNTY, NORTH CAROLINA
Union County has been experiencing frequent Sanitary Sewer Overflows in the Eastside
Sewer Collection System and surcharging metering stations for the Towns of Marshville
and Wingate. As a result, billing disputes have arisen between Union County and the
Towns. Hydrostructures, P.A. investigated the causes of these problems by monitoring
wastewater flow at various points in the Eastside System and evaluating the collected
data.
Sanitary Sewer Overflows (SSO's) and Capacity Issues
By contract with Union County, the Town of Wingate is allowed a peak flow rate of
646,780 gpd, the Town of Marshville is allowed peak flow rate of 490,000 gpd, and
Pilgrims Pride is allowed 950,000 gpd. Neither of these contracts defines "peak flow",
which is typical terminology to define instantaneous or short-lived peaks. The nature of
the discharge method used by Marshville and Pilgrims Pride allow the "peak flow" to be
a long, sustained peak. The combined "peak flow" of these three contracts is 2,086,780
gpd.
The City of Monroe allocates 1,950,000 gpd of treatment capacity to Union County via a
contract between the two local government entities. The County has allocated a peak
flow of 2,086,780 gpd to Marshville, Wingate and Pilgrim's Pride. Should these
discharging entities maintain peak flow for sustained periods, the combined flow from
these entities alone would exceed Union County's allocated capacity in the Monroe
WWTP.
In 1999 the City of Monroe and Union County partnered in a plan to upgrade the Monroe,
WWTP to create more treatment capacity, which would allow Union County additional
capacity. Before construction of the upgrade project began, Wampler Foods (now
Pilgrims Pride) and the Town of Marshville indicated to Union County that they would
divert their wastewater to a proposed new wastewater treatment facility by spring of 2002
(the proposed Sheaffer system). Taking this proposal on faith, the City/County
wastewater renovation project was put on hold since the added treatment capacity at the
Monroe WWTP would not be necessary. Unfortunately, the Sheaffer system project
never developed, leaving Union County with increasing capacity issues and no progress
toward capacity expansion.
Sewer Pumping Stations
Pump Station #3 serves Pilgrims Pride, Marshville, and Marshville West. The pump
station has a pumping capacity of 1,080,000 gpd with one pump running and 1,350,000
gpd with both pumps running (assuming 24-hour pump operation). The average peak
Draft

daily flow in dry wearer conditions from Pilgrims Pride, Marshville and Marshville
West totals to 50 000gpd. This peak daily flow is not the peak flow that is normally
discussed in municipal wastewater analyses. The typical diurnal peak occurs in morning
and afternoon cycles and last from one to three hours. Due to the discharge methods
employed at the wastewater lagoons of Pilgrim's Pride and Marshville, the time of day
and duration of the "peak flow" is dependent on the daily operations of these facilities.
Therefore, the peak flow may last hours if not days. J a r
Pilgrims Pride, Marshville and D
At a sustained combined average daily peak flow from Pil g
Marshville West, Pump Station #3 probably pumps continuously. State code (15A 'o�
NCAC 2H .0200) requires sewer pumping stations to provide pumping capacity 2.5 times
above the average daily flow to accommodate peak flow conditions (peak flow conditions
of the typical diurnal curve, not sustained peak flows). Under normal operating
conditions (average daily flow), Pump Station #3 operates in an acceptable range. Any
flow above average (which of course does occur even in the absence of inflow and
infiltration), would almost certainly result in surcharges or overflows:
During the rain event on May 22-23 approximately 1,800,000 gallons of I/1 was
measured entering Pump Station 3. The I/1 measured represents nearly a 100% increase
in the peak flow. Given the finite maximum capacity of Pump Station #3, the pumps
could not keep pace with the extreme peak flow caused by the I/I, resulting in
surcharging and SSO's.
Because a large portion of Marshville's system is collected in a lagoon and then pumped
to the gravity outfall, the total amount and peak of the extraneous flow conveyed to the
County is limited by the lagoon's pump capacity. For this reason we feel that the majority
of the I/1 measured from Marshville entered the system from the portion of Marshville's
collection system that gravity flows directly to the outfall and not to the lagoon. Were it
not for the lagoon (that effectively buffers or equalizes that portion of the flow), we
would have expected higher I/I at our meter location.
The same situation was seen for Pump Station #2. The capacity of the station is
1,584,000 mgd with one pump running and 2,592,000 mgd with both pumps running
(assuming 24-hour pump operation). Pump Station #2 serves the County Outfallup to
the station, Town of Whin ate, Wingate HalfwaBranch Outfall, and all the wastewater
from Pump atk n #3.The total average peak daily flow entering the pump station is
1,520,000 mgd. A single pump has to run constantly during peak periods to pump the
peak flow in dry conditions.
During the May 22-23 rain event, 2,850,000 gallons of I/1 entered the entered the system
from the County and Wingate sewer systems. Also Pump Station #3 was pumping into
Pump Station #2 at a full rate of 1,350,000 gpd with both pumps running. As a result
Pump Station #2 was inundated far in excess of its pumping capacity resulting in
surcharging and SSO's.

I/I of the magnitude experienced in these two areas is unacceptable by any standard of
measure and clearly causes operational difficulties that must be addressed. While
increased pumping capacity may help to prevent SSO's upstream of the Pump Stations #2
and #3, such remedies will only pass the problem downstream, resulting in over-capaci
at Pump Station 1 or capacity problems at Monroe's waater treatment facility.
Surcharging of Town's Metering Stations
During the flow monitoring, surcharging at the Marshville Metering Station was caused
by the Palmer-Bowlus flume used to measure the flow. The outfall line is 10-inch with
adequate slope to handle both normal and peak flow. The flume is 8-inch and installed
level, per design for a Palmer-Bowlus. During the May 22-23 rain event, the flow from
the 10-inch outfall would overwhelm the 8-inch flume restrict the flow and cause
surcharging.
The Wingate Metering Station surcharges because Pump Station #2 is under capacity, the
wet weather flow from the County's Outfall which includes the discharge from Pump
Station #3 and the flow from the Town of Wingate inundate the pump station. The pump
station cannot pump all the incoming flow, as a results the flow fills the two outfalls to
capacity. The Wingate outfall fills past the metering station causing the station to
surcharge.
Billing Disputes
Surcharged metering stations have resulted in billing discrepancies between the Towns
and Union County. The Pahner-Bowlus flumes used to measure flow must have free and
unobstructed flow conditions to measure flow accurately. During surcharge conditions
the flow is not free and unobstructed; the depth of flow is above the flume channel and
the meter records an inaccurate measurement. The meter reads the high level and records
the flow at the meters maximum set limit. These conditions will continue until capacity
issues are resolved.
The meter at the Wingate Metering Station appears to have been programmed incorrectly
when it was originally installed. The maximum flow limit was set at 3.07 mgd.
However, this number is actually the maximum flow for this meter in cubic feet per
second. The correct maximum setting is 1.99 mgd. When the meter station is surcharged
(immeasurable conditions), the meter reads 3.07 mgd instead of 1.99 mgd and Union
County over bills the Town of Wingate. Totalizer data from the Wingate Metering
Station showed that the meter kept reading at the maximum limit (3.07 mgd) for an
extended period (approximately 12 days) during normal flow conditions. This was due to
meter malfunction, most likely level sensor failure. There had been issues with debris
build-up on the bar screen at Pump Station #2 causing surcharge at the Wingate Metering
Station, consequently the bar screen was removed.
The Marshville Metering Station's maximum flow limit is set at 0.567 mgd (standard for
an 8" Palmer-Bowlus). However, the outfall is 10" upstream and downstream of the
Draft
4 of 19

meter with much greater carrying capacity. Our meter downstream showed an
instantaneous peak of 0.80 mgd during the rain event. More flow can go through the
meter than can be recorded; therefore the Town of Marshville is being under billed when
the metering station is surcharged.
Conclusions and Recommendations
The Eastside pump system operates near full capacity during dry weather conditions,
is eaves little capacity for extraneous flow during wet weather conditions. All the
systems served by the Eastside system contributed excessive levels of I/I far exceeding
pumping capacity, which causes SSO's and surcharging metering station. To alleviate
the billing disputes and these problems, Hydrostructures, P.A. has proposed some short-
term and long-term recommendations.
Short-term Recommendations:
• Union County, the Town of Marshville and the Town of Wingate should
aggressively continue I/I reduction programs. ✓
• Union County, the Town of Marshville and Pilgrims Pride should work
cooperatively on a lagoon optimization plan that could allow the lagoons to
serve as flow equalization facilities to reduce peak flows during wet weather
conditions.
• Pilgrims Pride should make efforts to divert stormwater and prevent it from
entering their wastewater lagoons.
• Construct a flow equalization structure for temporary storage to keep Pump
Station #2 from being inundated.
• The County should renegotiate or clarify the contracts with the Town of
Marshville and the Town of Wingate to clearly define flow allocation. The
contract should state an instantaneous peale as well as an average daily flow. The
County and the Towns need to c an w o is responsible for meter maintenance
and up keep to insure that meters are functioning properly and the billing is as
accurate as possible.
• Replace the Marshville Metering Station with a flume capable of handling high
peak flow rates during wet weather conditions.
Long-term Recommendations:
• Union County, the Town of Marshville and the Town of Wingate should
aggressively continue I/1 reduction programs. v—
• Union County should request the City of Monroe to resume upgrades to WWTP
and neaotiateaddilional treatment capacity. With the availability of this additional
treatment capacity, the County could renovate the pump stations to meet flow
requirements and comply with State Code for sewer pumping facilities. az5)(
• Union County may consider..diverting wastewater from Pump Station #3 to Anson
County or build a new regional WWTP to serve the entire system, removing the
County's reliance on the City of Monroe.

FLOW MONITORING AND CAPACITY ANALYSIS
EASTSIDE SEWER COLLECTION SYSTEM
UNION COUNTY, NORTH CAROLINA
I. INTRODUCTION
The Eastside Sewer Collection System was constructed by Union County in
1977 to provide service to the eastern portion of the County, as well as to the
municipalities of Wingate and Marshville and the large poultry processing
plant now known as Pilgrims Pride. After it is collected, the wastewater is
pumped to the City of Monroe Wastewater Treatment Plant for treatment and
disposal.
Since this system has been in service, the County has experienced a number of
problems, the most serious of which are:
1. Frequent Sanitary Sewer Overflows (SSO's) during rain events
2. Surcharging of Metering Stations for Wingate and Marshville
3. Billing Disputes between Union County and the Towns
Hydrostructures, P.A. was retained by the County in May 2003 to monitor and
analyze the wastewater flows from the various entities served by the Eastside
System to investigate the causes of the problems currently being experienced
and recommend the best course of action to alleviate these problems. This
report presents the fmdings of this analysis.
H. EXISTING SEWER COLLECTION SYSTEM
Draft
The Eastside Sewer Collection System consists of three sub -basins, which are
described in detail in the following sections starting upstream and proceeding
downstream. A map of the entire system is included in Appendix A of this
report.
A. Pump Station #3 Sub -basin - The first sub -basin includes approximately
10,400 linear feet of 15-inch and 990 feet of 10-inch gravity outfall and
serves the portion of the County to the north of Marshville, as well as the
Town of Marshville and Pilgrims Pride. The flow from this entire area is
collected and transported to Pump Station #3. From here, it is pumped to
sub -basin #2 via approximately 17,400 linear feet of 12-inch ductile iron
force main. Pump Station #3 contains duplex pumps, capable of pumping
750 gallons per minute (gpm) each or 950 gpm while operating
simultaneously.
The majority of the flow from the Town of Marshville enters the County's
outfall system at a metering station on the North Side of Town near Buck
6of19

Branch Creek. A small portion of the Town's system, referred to as
Marshville West, enters the outfall system at a metering station on the
west side of Town near Highway 74. The flow from Pilgrims Pride also
enters the outfall system on the west side of Marshville.
B. Pump Station #2 Sub -basin — The second sub -basin includes
approximately 350 linear feet of 18-inch and 9,200 feet of 15-inch gravity
outfall serving the area of the County on the northwest side of Wingate, as
well as the Town of Wingate itself. The flow from this subsystem, and
that from Sub -basin #3, is collected -and transported to Pump Station #2.
From there, it is pumped to Sub -basin #1 via approximately 5,700 linear
feet of 12-inch ductile iron force main. Pump Station #2 contains duplex
pumps, capable of pumping 1,100 gpm each or 1,800 gpm pumping
simultaneously.
C. Pump Station #1 Sub -basin - The third sub -basin includes
approximately 3,600 linear feet of 15-inch gravity outfall and serves a
portion of the County on the northwest side of the Town of Wingate. The
flow from this sub -basin, along with that from Sub -basins 2 and 3, is
collected and transported to Pump Station #1. From there, it is pumped to
the City of Monroe's Wastewater Treatment Plant via approximately
4,900 feet of 14-inch force main. Pump Station #1 contains duplex
submersible pumps, capable of pumping 1,800 gpm each or 2,465gpm
pumping simultaneously.
III. SYSTEM FLOW DATA
Draft
In order to investigate the cause or causes of the problems being experienced
by the Eastside Collection System, several different types of data were
obtained. First, daily meter readings were obtained from each of the seven
permanent metering stations within the Eastside system for the period from
January through July of 2003. This data is located in Appendix B. Second,
electronic, data -logging flow meters were installed at key points within the
system to evaluate the instantaneous flow rates from different parts of the
system under various conditions. Electronic flow meter data is located in
Appendix C. These are discussed in detail in the following section.
A. Permanent Metering Devices
Within the Eastside system, Union County utilizes 4 permanent meters for
billing purposes and 3 permanent meters to monitor flow in Pump Stations
#1, #2, and #3. The permanent billing meters record flow from the
Marshville outfall, Pilgrims Pride, Marshville West, and Wingate.
1. Marshville Metering Station — Wastewater from the majority of the
Town of Marshville is metered through an 8-inch Palmer-Bowlus
7 of 19

flume. An ultrasonic transducer measures the depth of flow and
calculates flow rate. The meter measures flow rate between 14 and
310 gpm (20,160 to 446,400 gpd).
- Marshville West MeteringStation — Marshville West's wastewater
\,�3 flow is also metered through Stan 8-inch Palmer-Bowlus flume. The
�.�� meter uses an ultrasonic transducer to measure depth of flow and
I calculated flow rate. The meter best measures flow between 14 to 310
m (20,160 to 446,400 gpd).
Draft
Pilgrims Pride Metering Station — Wastewater flow from Pilgrims
Pride is monitored by a 12-inch Palmer-Bowlus flume and depth
measured by a ultrasonic level transducer. The acceptable
measurement range is between 31 to 752 gpm or 44,640 to 1,082,880
gpd.
4. Wingate Metering Station — Wingate's wastewater flow is monitored
through a 15-inch Palmer-Bowlus flume and depth measured by an
ultrasonic transducer. The acceptable flow range for his meter is 49 to
1,385 gpm (70,560 to 1,994,400 gpd) .
5. Pump Station #1 Metering Station — Flow through Pump Station #1
is measured by a Mag Meter. The Mag meter is located on the
discharge side of the pump station. The flow is recorded with a
totalizer and periodically read and recorded in hard copy form.
6. Pump Station #2 Metering Station — Flow through Pump Station #2
is measured by a Mag Meter. The Mag meter is located on the
discharge side of the pump station. The flow is recorded with a
totalizer and periodically read and recorded in hard copy form.
7. Pump Station #3 Metering Station — Flow through Pump Station #3
is measured by a Mag Meter. The Mag meter is located on the
discharge side of the pump station. The flow is recorded with a
totalizer and periodically read and recorded in hard copy form.
B. Temporary Metering Devices
Seven electronic flow meters were used to monitor the instantaneous flow
in the system during this investigation. Meter locations were selected to
isolate flow coming from Marshville, Pilgrims Pride, Wingate and the
County lines in order to effectively investigate the system.
The electronic flow meters operate using the continuity equation, which
states that the average velocity of a liquid passing through a pipe times the
cross -sectional area of flow equals the rate of flow. The data is
8of19

Draft
continuously gathered and averaged in 15-minute increments and stored in
the meter. Hydrostructures, P.A. technicians periodically visited each site
(approximately once per week or after every major rain event) to
download the data and evaluate and/or calibrate the meters.
1. Flow Meter #1 - Meter 1 was located in the old Buck Branch
Monitoring Station on Marshville's outfall at the County tie in. Flow
Meter #1 measured flow entering the Marshville Outfall downstream
of the Town's permanent meter and Flow Meter #3. There is
approximately 4,900 feet of outfall between Flow Meter #1 and Flow
Meter #3 along Buck Branch. Because the outfall follows the run of
the Branch, we suspected that the outfall would experience some
inflow/infiltration during a rain event. Therefore, Flow Meter #1 was
located in a position to measure the extraneous flow entering the
system along this outfall.
2. Flow Meter #2 - Flow Meter #2 monitored the flow in the County
outfall from Pilgrims Pride and Marshville West. Flow Meter #2
checked the quantity of flow recorded by the Pilgrims Pride and
Marshville West and measured flow entering the County's outfall
between these connections and Pump Station #3.
3. Flow Meter #3 - Flow Meter #3, located in the manhole directly
downstream of the Marshville Metering Station, measured flow
coming downstream out of the new Marshville Monitoring Station.
The primary reason for placing Flow Meter #3 at this location was to
check the accuracy of the permanent flow meter during high flow
conditions. Also, it monitored he amount of VI entering the
Marshville outfall downstream of the permanent Marshville metering
station.
4. Flow Meter #4 - Flow Meter #4 was located on the County's outfall
upstream of Pump Station 2. Flow Meter #4 monitored flow between
Pump Station 3 and Pump Station 2 to calculate the volume of
extraneous flow (1/I) entering the County outfall between to two pump
stations.
5. Flow Meter #5 — Flow Meter #5 was located on Wingate's outfall
downstream of the Wingate Metering Station. At this location, Flow
Meter #5 measured the combined flow from both of the Wingate
outfalls and checked the accuracy of the Wingate Meter. The meter
was also located downstream of the Wingate Permanent Metering
Station in order to determine the sequence of surcharge. This
sequence will help determine the contributors to the surcharge
problems at Pump Station #2 and Wingate's Metering Staion.
9of19

6. Flow Meter #6 — Flow Meter #6 measured flow upstream of the
Wingate Permanent Metering Station. This location allowed the flow
from Wingate to be measured and compared with the recorded flow at
the town's meter. Also at this location, the metering station was
monitored on both sides by Flow Meter #5 and Flow Meter #6 to
determine the sequence of surcharge.
7. Flow Meter #7 — Flow Meter #7 was located in manhole #MB 11 on
Wingate's outfall. The purpose of this location was to monitor flow
from the Halfway Branch outfall.
IV. EVALUATION OF PROBLEMS
This section evaluates each of the three major problems with the Eastside
collection system identified in Section I of his report.
A. Frequent Sanitary Sewer Overflows (SSO's) during rain events
The United States Environmental Protection Agency (EPA) and the North
Carolina Division of Water Quality have both established guidelines that
call for the elimination of SSO's in sewer collection systems. Union
County has also set this as a goal. Unfortunately, the Eastside system has
experienced a number of overflows this year as indicated in the following

Draft
se 20 spills released a total of more than 2 million gallons of untreated
wastewater into the environment. This is unacceptable to the County and
the regulatory agencies.
Capacity Issues
The Eastside collection system is under capacity to handle the allocated
flow from the Town of Wingate, Town of Marshville, and Pilgrams Pride.
According to the Contract between the County and the Town of
Marshville, the Town is allocated 376,000 gallon per day of wastewater
capacity on a monthly average with a peak flow rate of 490,000 gallons.
Pilgrams Pride is allocated 950,000 gallons per day (on a 24-hour average)
through its pre-treatment agreement with the City of Monroe. The
Contract between the County and the Town of Wingate allows a peak flow
rate of 646,780 gallons per day from the Town. Neither of these contracts
defines "peak flow", which is typical terminology to define instantaneous
or short-lived peaks. The nature of the discharge method used by
Marshville and Pilgrims Pride allow the "peak flow" to be a long,
sustained peak. The combined "peak flow" of these three contracts is
2,086,780 gpd.
The City of Monroe allocates 1,950,000 gpd of treatment capacity to
Union County via a contract between the two local government entities.
The County has allocated a peak flow of 2,086,780 gpd to Marshville,
Wingate and Pilgrim's Pride. Should these discharging entities maintain
peak flow for sustained periods, the combined flow from these entities
alone would exceed Union County's allocated capacity in the Monroe
WWTP.
Furthermore, when the Towns and Pilgrams Pride is supplying wastewater
at their peak allocated flow, the County leaves no capacity for its own
flow. The City of Monroe bills Union County at a higher rate when the
flow exceeds the Contract amount. The extra cost for Union County is not
incurred on the Towns or Pilgrams Pride.
Union County acknowledged the problem with allocated capacity and
made efforts to remedy the situation. In 1999 the City of Monroe and
Union County partnered in a plan to upgrade the Monroe WWTP to create
more treatment capacity, which would allow Union County additional
capacity. After the engineering was completed but before construction of
the upgrade project began, Wampler Foods (now Pilgrims Pride) indicated
to Union County that they would divert their wastewater to a proposed
new wastewater treatment facility by spring of 2002 (the proposed
Sheaffer system). A letter from Wampler Foods to the County on
February 14, 2000 stated,
11 of 19

Draft
"We are planning on the potable water to be available in the
spring of 2002 which is the same time we are scheduled to
move to the Sheaffer system. The pipeline capacity, which we
were using, will give Union County the growth potential they
are looking for without any new capital money."
Marshville also intended to join the Sheaffer system with Wampler Foods.
Taking this proposal on faith, the upgrade project was put on hold since
the added treatment capacity at the Monroe WWTP would not be
necessary. Unfortunately, the Sheaffer system project never developed,
leaving Union County with increasing capacity issues and no progress
toward capacity expansion.
The Eastside collection system is in a difficult position, because not only
is the system under capacity to handle the allocated peak flow, it is nearly
at capacity to handle peak dry weather flow. For example, the current
pumping capacity of Pump Station #3 is approximately 750 gpm
(1,080,000 gpd) with one pump running and 950 gpm (1,350,000 gpd)
with both pumps running. The total average peak daily flows from
Pilgrams Pride (750,000 gpd), Marshville (300,000 gpd) and Marshville
West (25,000 gpd) requires one pump to cycle continuously just to meet
demand. The meter on the pump discharge for Pump Station #3 confirms
this. This peak daily flow is not the peak flow that is normally discussed
in municipal wastewater analyses. A typical diurnal peak occurs in
morning and afternoon cycles and last from one to three hours. Due to the
discharge methods employed at the wastewater lagoons of Pilgrim's Pride
and Marshville, the time of day and duration of the peak flow is dependent
on the operation of the facility. Therefore, depending on the daily
operating conditions, the peak flow may last hours if not days.
Also, the peak allocated flow rate from Pilgrams Pride (950,000 gpd) and
the Town of Marshville (490,000 gpd) totals to 1,440,000 gallons per day
which exceeds the pump station capacity. At a sustained combined
average daily peak flow from Pilgrims Pride, Marshville and Marshville
West, Pump Station #3 pumps continuously. State code (15A NCAC 2H
.0200) requires sewer pumping stations to provide pumping capacity 2.5
times above the average daily flow to accommodate peak flow conditions
(peak flow conditions of the typical diurnal curve, not sustained peak
flows). Under normal operating conditions (average daily flow), Pump
Station #3 operates in an acceptable range. Any flow above average
(which of course does occur even in the absence of inflow and
infiltration), would almost certainly result in surcharges or overflows.
A similar situation exists at pump station #2, which has a pumping
capacity of 1,100 gpm (1,584,000 gpd) with one pump running and 1,800
gpm (2,592,000 gpd) with both pumps running. The total average peak
12 of 19

Draft
daily flows from pump station #3 (1,080,000 gpd) and Wingate (320,000
gpd) and Union County (120,000 gpd) require at least one pump to cycle
continuously and at times a second pump must cycle to meet demand.
With the allocated flow from Wingate at 647,780 gpd and the maximum
discharge rate of 1,350,000 gpd from Pump Station #3, there appears to be
approximately 595,220 gpd of capacity at Pump Station #2 while running
both pumps.
Excessive I/I
With the Eastside system barely meeting the daily dry weather flow
demand, the system has little capacity for excess flow from wet weather
events. Periods of wet weather, such as those experienced this year, result
in large volumes of extraneous rainwater and groundwater entering the
collection system through defects in the pipes, manholes, and service
connections. This extraneous flow is referred to as inflow and infiltration
(I/I). When the total of average daily wastewater flow plus I/1 exceeds the
capacity of the system, the surplus exits the system as an SSO.
To evaluate the effect of wet weather conditions on the Eastside
Collection System, we utilized data from a rain event on May 22, 2003,
when a total of 1.8 inches of precipitation fell over a 24-hour period. The
instantaneous data from the temporary flow meters during this event were
compared with dry weather data to estimate the quantity of 1/1 entering the
system. Because of the rapid surcharge in the majority of these locations,
all data should be considered approximate.
The following section presents the analysis of extraneous flow on a sub -
basin by sub -basin basis:

Our analysis of the data indicates that there are a number of major
contributors of extraneous flow in the Pump Station #3 Sub -basin:
1. Marshville Outfall — According to our data, approximately 250,000
gallons of 1/I entered this line between Flow Meters #1 and #3. This
occurred in only approximately 4,800 feet of line, indicating that
significant problems exist in this area. Furthermore, because the I/1 enters
the system downstream of Marshville's permanent meter this flow is un-
metered by the County.
2. Marshville Collection System — Flow Meter #3 indicated that
approximately 680,000 gallons of I/1 entered the Marshville collection
system during this event. Because a large portion of Marshville's system is
collected in a lagoon and then pumped to the gravity outfall, the total
13 of 19

Draft
amount and peak of the extraneous flow conveyed to the County is limited
by the lagoon's pump capacity. For this reason we feel that the majority of
the I/I measured during this study is entering the system from the portion
of Marshville's collection system that gravity flows to the outfall and not
to the lagoon. According to information provided by the Town's staff,
Marshville's lagoon pump station is capable of pumping approximately
220,000 gpd with one pump and 360,000 gpd with two pumps. Because of
capacity issues at the station's discharge point, the Town is only able to
run both pumps during dry periods. The lagoon covers an area of
approximately 7 acres. During the rain event in question (1.8 inches),
approximately 342,000 gallons of rainwater fell directly on the lagoon.
This alone exceed the pumping capacity with one pump running.
3. Marshville West — While we did not meter this area separately the
permanent meter in the Marshville West area increased from an average
dry weather flow of 25,000 gpd to 123,000 gallons on May 22 and 80,000
gpd on May 23. This is a significant increase from a relatively small area,
indicating that problems exist in the Marshville West collection system.
4. Pilgrims Pride Lagoon — Pilgrims Pride has 2 lagoons with a total surface
area of approximately 8 acres. During the rain event on May 22,
approximately 387,000 gallons of rainwater fell directly into the lagoon.
Also, a significant area of the plant site currently drains into the lagoon,
allowing more extraneous flow into the system. Fortunately, Pilgrims
Pride was attempting to equalize during this peak, so the peak from these
lagoons came several hours after the peak from Marshville, thereby
reducing the severity of the surcharge and subsequent SSO at Pump
Station #3. However significant quantities of stormwater is entering the
system from the Pilgrims Pride site.
5. Union County Outfall to Pump Station #3 — Subtracting the flows from
Marshville West and Pilgrams Pride, we estimate that approximately
900,000 gallons of I/I entered the County Outfall upstream of the tie-in
point of the main Marshville Outfall. The instantaneous peak flow was
approximately 1,900,000 gpd.
Pump Station #2 Sub -basin
There are also major I/I contributors in the Sub -basin served by Pump Station
#2.
1. Union County Outfall to Pump Station #2 — This area was monitored by
Flow Meter #4. According to our data, approximately 1,150,000 gallons
of I/I entered this line on May 22 and 23. The instantaneous peak flow
during the rain event was approximately 2,500,000 gpd. (Note: Internal
television inspection performed as part of a recent sewer rehabilitation
14 of 19

Draft
project confirmed that portions of this line were in poor condition.
Infiltration rates observed were heavy during a relatively dry period).
2. Wingate Collection System — This area was monitored by Flow Meter
#5. According to our data, approximately 1,700,000 gallons of I/I entered
from the Wingate System on May 22 and 23. The instantaneous peak flow
during the rain event was approximately 1,700,000 gpd.
3. Wingate Halfway Branch Outfall — This area was monitored by Flow
Meter #7. We found approximately 320,000 gallons of I/I entered the
system upstream of this meter during the May 22-23 rain event. This flow
is included in Flow Meter #5 downstream. However, the level sensor
stopped functioning late on the 22", so all of this extraneous flow was
recorded on the 22°'. The instantaneous peak flow during the event was
approximately 600,000 gpd
B. Surcharging of Metering Stations for Wingate and Marshville
Both Marshville and Wingate relocated their permanent metering stations
from their original locations due to surcharge conditions that existed in the
system. Unfortunately, they are still surcharging. As mentioned earlier,
the County's outfall system can barely handle the dry weather peak flows
in the area. It is quickly inuniiated during heavy rain events, causing the
system to surcharge very quickly.
1. Marshville Outfall Surcharge — Our temporary flow meters indicated
that any surcharges on this line were not caused by the outfall, they
were caused by the Palmer-Bowlus flume itself The outfall line is
10-inch gravity with good slope, but the flume is only an 8-inch and
relatively level. It simply cannot handle the peak flows occurring
during wet weather periods.
2. Wingate Outfall Surcharge - There are two main issues regarding
surcharge of the Town of Wingate's outfall. First, the meter is
periodically surcharged during wet weather conditions due to limited
pumping capacity at Pump Station #2. Excess flow from both the
County and Wingate outfalls inundate the pump station causing
surcharge up both outfalls including Wingate's metering station. The
Palmer-Bowlus flume will only work during free flow conditions,
not surcharge. Based on an analysis of data from the Wingate
permanent meter, it also appears that there is periodic surcharge at
the permanent meter during dry weather conditions. This could be
caused by temporary blockages in the line or at the bar screen at
Pump Station #2 (since removed) or merely be false readings from
the meter itself.
15 of 19

Draft
The second issue involves overflows that have occurred on the
Wingate outfall upstream of the Wingate permanent metering station
near McIntyre Road. The Town thought the overflows were possibly
caused by the backup from Pump Station #2. However, data taken
from the temporary flow meters showed that the initial surcharge in
the Town's 12" outfall was caused by the flow from upstream
exceeding the capacity of the line. However, Pump Station #2 is
soon inundated causing the surcharge to worsen.Because of
surcharge conditions caused by high peak flows, the metering
stations do not function properly, causing billing disputes. These
disputes are discussed in the section C below
C. Billing Disputes between Union County and the Towns
The high peak flow rates and surcharge conditions described above not
only cause operational difficulties for the County, they also result in
frequent disagreements over billing discrepancies. The major billing
issues we discovered are:
• The Palmer-Bowlus type flume used in the permanent metering
stations do not work under surcharge or submerge conditions. Neither
do the electronics in the ultrasonic level sensors. Flow meters of this
type only measure level to calculate flow, they do not measure
velocity. For this reason there has to be free or unobstructed flow
conditions. During submerged conditions the level sensor measures
the elevated level but it is no longer free flow and the formula used to
calculate flow becomes invalid. In this situation the flow meter usually
defaults to the maximum flow setting programmed in the instrument.
Debris and solids can also foul the sensors causing false readings and
errors. Both towns relocated their permanent metering stations from
their original locations in an attempt to address the surcharge problem.
However, they still occur frequently at the Wingate metering station.
■ The meter at the Wingate metering station appears to have been
programmed wrong when it was originally installed. The maximum
flow is set at "3.07" mgd. However, this number is actually the
maximum flow for this meter in cubic feet per second. The actual
maximum flow for this meter should be 1.99 mgd. Therefore,
whenever the flume defaults to the maximum flow, the Town of
Wingate is over billed for the duration of the time the flow was peaks.
In early January of 2003, this incorrect reading (3.07 mgd) was
sustained for eleven consecutive days when all other data showed that
flows should be normal. This was due to either level sensor failure or
a blockage downstream causing a surcharge condition.
16 of 19

• The Marshville meter does not record peak flows in excess of 0.576
mgd (400 gpm). This is the maximum flow rate for an 8" Pahner-
Bowlus flume and therefore is programmed into the meter. However,
the temporary flow meter we installed downstream of this meter
recorded an instantaneous peak flow rate of 0.80 mgd (556 gpm).
Therefore, the Town of Marshville is being under billed for any period
in which the instantaneous flow is greater than 0.576 mgd.
• Both towns exceed the maximum flow rates allowable under their
contracts with the County. Even assuming that the stated maximum is
a daily maximum and not an instantaneous maximumtheyboth can
exceed their maximum flow during rain events. During our study
period, Marshville exceeded their contract on 2 different occasions,
and Wingate exceeded theirs on 4 occasions.
These issues should be resolved so that all of the entities involved have
confidence that they are being billed for the correct amount of flow.
V. CONCLUSIONS AND RECOMMENDATIONS
Conclusions
Draft
It is obvious that the Eastside Sewer Collection System has problems with
insufficient capacity based on the number of overflows that have been
observed this year. The system operates near its capacity during dry weather
conditions, which leaves very little capacity for extraneous flows (I/I) during
wet weather conditions. Unfortunately, all of the systems served by the
Eastside system are contributing excessive levels of 1/1, which quickly
overwhelms the capacity and causes surcharging and SSO's.
The County's outfall lines are constructed of vitrified clay pipe that is
approximately 26 years old. Internal television inspections performed on the
line indicated that numerous areas of joint infiltration and cracked pipe are
present. The County started rehabilitating a portion of the outfall to Pump
Station #2 this summer, and plans to continue this rehabilitation program in
the future.
The collection systems in both Wingate and Marshville are considerably older
than the County outfall system, and both also have significant I/1 problems.
Wingate conducted a Sewer System Evaluation Study (SSES) in 1999-2000,
which was performed by Hydrostructures, P.A. Recent conversations with
Town staff indicate that they have rehabilitated manholes and repaired some
defects in collection mains. They also have budgeted for line rehabilitation.
The Town of Marshville is also involved in UI reduction efforts including line
replacements and manhole rehabilitation.

Draft
Recommendations
Given the County's and the regulatory agencies' stated goals of eliminating
SSO's, it is vital that steps be taken the improve the I/I problems being
experienced by all of the principals in the Eastside System. Our
recommendations are as follows:
Short-term Recommendations:
• The only short-term solution for the capacity and SSO problems at
Pump Station #2 is the construction of a flow equalization structure or
structures, which will provide temporary storage for excess flow
during rain events. The stored flow can then be released back into the
system during dry low flow periods.
• Union County, the Town of Marshville and the Town of Wingate
should all aggressively continue (or start) I/I reduction programs.
• Union County, the Town of Marshville, and Pilgrims Pride should
work cooperatively on a lagoon optimization plan that could allow the
lagoons to serve as flow equalization facilities, shaving off the high
peaks during wet weather conditions. Pumping during periods of dry
weather (when the system can handle it) provides sufficient freeboard
for rain events, allowing the lagoons to hold as much flow as possible
during rain events. Pilgrims Pride has already begun such a plan, and
this should be continued and improved where possible. A similar plan
is being developed by the Town of Marshville.
• As stated earlier in this report, a large portion of the stormwater on the
Pilgrims Pride site is diverted to the lagoons. Efforts should be made
to install mechanisms or pipes to divert flow away from the lagoons.
Similar efforts should be investigated at the Marshville lagoons.
• Renegotiate or clarify the contracts with both the Town of Marshville
and the Town of Wingate to clearly define flow allocation, particularly
maximum instantaneous flow. It was the County's intent that the peak
flow rates shown in the contracts to be maximum "instantaneous"
flow, and the outfalls and pump stations were designed accordingly.
The extremely high peak flow rates are the major causes of SSO's in
the Eastside system.
• The County and the Towns need to clarify who is responsible for
meter maintenance and up keep. This will insure the meters are
functioning properly and the billing is as accurate as possible. Also
develop better communication between the Coun and Towns to
notify one another when a meter is malfunctioning.
18of19

• Replace Marshville metering station with a flume capable of handling
high peak flow rates seen during wet weather conditions.
Long-term Recommendations:
• Union County, the Town of Marshville and the Town of Win to
should all aggressively continue I/I reduction programs.
• Union County should request the City of Monroe to resume upgrades
to WWTP and negotiate additional treatment capacity. With the
availability of this additional treatment capacity, the County could
renovate the pump stations to meet flow requirements and comply with
State Code for sewer pumping facilities. 01'6 J,
• Union County may consider diverting wastewater from Pump Station
#3 to Anson County or build a new regional WWTP to serve the entire
system, removing the County's reliance on the Cityoe.

EXECUTIVE SUMMARY
FLOW MONITORING AND CAPACITY ANALYSIS
EASTSIDE SEWER COLLECTION SYSTEM
UNION COUNTY, NORTH CAROLINA
Union County has been experiencing frequent Sanitary Sewer Overflows in the Eastside
Sewer Collection System and surcharging metering stations for the Towns of Marshville
and Wingate. As a result, billing disputes have arisen between Union County and the
Towns. Hydrostructures, P.A. investigated the causes of these problems by monitoring
wastewater flow at various points in the Eastside System and evaluating the collected
data.
Sanitary Sewer Overflows (SSO's) and Capacity Issues
By contract with Union County, the Town of Wingate is allowed a peak flow rate of
646,780 gpd, the Town of Marshville is allowed peak flow rate of 490,000 gpd, and
Pilgrims Pride is allowed 950,000 gpd. Neither of these contracts defines "peak flow",
which is typical terminology to define instantaneous or short-lived peaks. The nature of
the discharge method used by Marshville and Pilgrims Pride allow the "peak flow" to be
a long, sustained peak. The combined "peak flow" of these three contracts is 2,086,780
gpd.
The City of Monroe allocates 1,950,000 gpd of treatment capacity to Union County via a
contract between the two local government entities. The County has allocated a peak
flow of 2,086,780 gpd to Marshville, Wingate and Pilgrim's Pride. Should these
discharging entities maintain peak flow for sustained periods, the combined flow from
these entities alone would exceed Union County's allocated capacity in the Monroe
WWTP.
In 1999 the City of Monroe and Union County partnered in a plan to upgrade the Monroe
WWTP to create more treatment capacity, which would allow Union County additional
capacity. Before construction of the upgrade project began, Wampler Foods (now
Pilgrims Pride) and the Town of Marshville indicated to Union County that they would
divert their wastewater to a proposed new wastewater treatment facility by spring of 2002
(the proposed Sheaffer system). Taking this proposal on faith, the City/County
wastewater renovation project was put on hold since the added treatment capacity at the
Monroe WWTP would not be necessary. Unfortunately, the Sheaffer system project
never developed, leaving Union County with increasing capacity issues and no progress
toward capacity expansion.
Sewer Pumping Stations
Pump Station #3 serves Pilgrims Pride, Marshville, and Marshville West. The pump
station has a pumping capacity of 1,080,000 gpd with one pump running and 1,350,000
gpd with both pumps running (assuming 24-hour pump operation). The average peak

daily flow in dry weather conditions from Pilgrims Pride, Marshville and Marshville
West totals to 1,050,000 gpd. This peak daily flow is not the peak flow that is normally
discussed in municipal wastewater analyses. The typical diurnal peak occurs in morning
and afternoon cycles and last from one to three hours. Due to the discharge methods
employed at the wastewater lagoons of Pilgrim's Pride and Marshville, the time of day
and duration of the "peak flow" is dependent on the daily operations of these facilities.
Therefore, the peak flow may last hours if not days.
At a sustained combined average daily peak flow from Pilgrims Pride, Marshville and
Marshville West, Pump Station #3 probably pumps continuously. State code (15A
NCAC 2H .0200) requires sewer pumping stations to provide pumping capacity 2.5 times
above the average daily flow to accommodate peak flow conditions (peak flow conditions
of the typical diurnal curve, not sustained peak flows). Under normal operating
conditions (average daily flow), Pump Station #3 operates in an acceptable range. Any
flow above average (which of course does occur even in the absence of inflow and
infiltration), would almost certainly result in surcharges or overflows.
During the rain event on May 22-23 approximately 1,800,000 gallons of I/I was
measured entering Pump Station 3. The I/I measured represents nearly a 100% increase
in the peak flow. Given the finite maximum capacity of Pump Station #3, the pumps
could not keep pace with the extreme peak flow caused by the I/I, resulting in
surcharging and SSO's.
Because a large portion of Marshville's system is collected in a lagoon and then pumped
to the gravity outfall, the total amount and peak of the extraneous flow conveyed to the
County is limited by the lagoon's pump capacity. For this reason we feel that the majority
of the I/I measured from Marshville entered the system from the portion of Marshville's
collection system that gravity flows directly to the outfall and not to the lagoon. Were it
not for the lagoon (that effectively buffers or equalizes that portion of the flow), we
would have expected higher I/I at our meter location.
The same situation was seen for Pump Station #2. The capacity of the station is
1,584,000 mgd with one pump running ning and 2,592,000 mgd with both pumps running
(assuming 24-hour pump operation). Pump Station #2 serves the County Outfall up to
the station, Town of Wingate, Wingate Halfway Branch Outfall, and all the wastewater
from Pump Station #3. The total average peak daily flow entering the pump station is
1,520,000 mgd. A single pump has to run constantly during peak periods to pump the
peak flow in dry conditions.
During the May 22-23 rain event, 2,850,000 gallons of I/I entered the entered the system
from the County and Wingate sewer systems. Also Pump Station #3 was pumping into
Pump Station #2 at a full rate of 1,350,000 gpd with both pumps running. As a result
Pump Station #2 was inundated far in excess of its pumping capacity resulting in
surcharging and SSO's.
Draft

I/I of the magnitude experienced in these two areas is unacceptable by any standard of
measure and clearly causes operational difficulties that must be addressed. While
increased pumping capacity may help to prevent SSO's upstream of the Pump Stations #2
and #3, such remedies will only pass the problem downstream, resulting in over -capacity
at Pump Station 1 or capacity problems at Monroe's wastewater treatment facility.
Surcharging of Town's Metering Stations
During the flow monitoring, surcharging at the Marshville Metering Station was caused
by the Palmer-Bowlus flume used to measure the flow. The outfall line is 10-inch with
adequate slope to handle both normal and peak flow. The flume is 8-inch and installed
level, per design for a Palmer-Bowlus. During the May 22-23 rain event, the flow from
the 10-inch outfall would overwhelm the 8-inch flume restrict the flow and cause
surcharging.
The Wingate Metering Station surcharges because Pump Station #2 is under capacity, the
wet weather flow from the County's Outfall which includes the discharge from Pump
Station #3 and the flow from the Town of Wingate inundate the pump station. The pump
station cannot pump all the incoming flow, as a results the flow fills the two outfalls to
capacity. The Wingate outfall fills past the metering station causing the station to
surcharge.
Billing Disputes
Surcharged metering stations have resulted in billing discrepancies between the Towns
and Union County. The Palmer-Bowlus flumes used to measure flow must have free and
unobstructed flow conditions to measure flow accurately. During surcharge conditions
the flow is not free and unobstructed; the depth of flow is above the flume channel and
the meter records an inaccurate measurement. The meter reads the high level and records
the flow at the meters maximum set limit. These conditions will continue until capacity
issues are resolved.
The meter at the Wingate Metering Station appears to have been programmed incorrectly
when it was originally installed. The maximum flow limit was set at 3.07 mgd.
However, this number is actually the maximum flow for this meter in cubic feet per
second. The correct maximum setting is 1.99 mgd. When the meter station is surcharged
(immeasurable conditions), the meter reads 3.07 mgd instead of 1.99 mgd and Union
County over bills the Town of Wingate. Totalizer data from the Wingate Metering
Station showed that the meter kept reading at the maximum limit (3.07 mgd) for an
extended period (approximately 12 days) during normal flow conditions. This was due to
meter malfunction, most likely level sensor failure. There had been issues with debris
build-up on the bar screen at Pump Station #2 causing surcharge at the Wingate Metering
Station, consequently the bar screen was removed.
The Marshville Metering Station's maximum flow limit is set at 0.567 mgd (standard for
an 8" Palmer-Bowlus). However, the outfall is 10" upstream and downstream of the

meter with much greater carrying capacity. Our meter downstream showed an
instantaneous peak of 0.80 mgd during the rain event. More flow can go through the
meter than can be recorded; therefore the Town of Marshville is being under billed when
the metering station is surcharged.
Conclusions and Recommendations
The Eastside pump system operates near full capacity during dry weather conditions,
which leaves little capacity for extraneous flow during wet weather conditions. All the
systems served by the Eastside system contributed excessive levels of I/I far exceeding
pumping capacity, which causes SSO's and surcharging metering station. To alleviate
the billing disputes and these problems, Hydrostructures, P.A. has proposed some short-
term and long-term recommendations.
Short-term Recommendations:
• Union County, the Town of Marshville and the Town of Wingate should
aggressively continue I/1 reduction programs.
• Union County, the Town of Marshville and Pilgrims Pride should work
cooperatively on a lagoon optimization plan that could allow the lagoons to
serve as flow equalization facilities to reduce peak flows during wet weather
conditions.
• Pilgrims Pride should make efforts to divert stormwater and prevent it from
entering their wastewater lagoons.
• Construct a flow equalization structure for temporary storage to keep Pump
Station #2 from being inundated.
• The County should renegotiate or clarify the contracts with the Town of
Marshville and the Town of Wingate to clearly define flow allocation. The
contract should state an instantaneous peak as well as an average daily flow. The
County and the Towns need to clarify who is responsible for meter maintenance
and up keep to insure that meters are functioning properly and the billing is as
accurate as possible.
• Replace the Marshville Metering Station with a flume capable of handling high
peak flow rates during wet weather conditions.
Long-term Recommendations:
• Union County, the Town of Marshville and the Town of Wingate should
aggressively continue I/I reduction programs.
• Union County should request the City of Monroe to resume upgrades to WWTP
and negotiate additional treatment capacity. With the availability of this additional
treatment capacity, the County could renovate the pump stations to meet flow
requirements and comply with State Code for sewer pumping facilities.
• Union County may consider diverting wastewater from Pump Station #3 to Anson
County or build a new regional WWTP to serve the entire system, removing the
County's reliance on the City of Monroe.

FLOW MONITORING AND CAPACITY ANALYSIS
EASTSIDE SEWER COLLECTION SYSTEM
UNION COUNTY, NORTH CAROLINA
I. INTRODUCTION
The Eastside Sewer Collection System was constructed by Union County in
1977 to provide service to the eastern portion of the County, as well as to the
municipalities of Wingate and Marshville and the large poultry processing
plant now known as Pilgrims Pride. After it is collected, the wastewater is
pumped to the City of Monroe Wastewater Treatment Plant for treatment and
disposal.
Since this system has been in service, the County has experienced a number of
problems, the most serious of which are:
1. Frequent Sanitary Sewer Overflows (SSO's) during rain events
2. Surcharging of Metering Stations for Wingate and Marshville
3. Billing Disputes between Union County and the Towns
Hydrostructures, P.A. was retained by the County in May 2003 to monitor and
analyze the wastewater flows from the various entities served by the Eastside
System to investigate the causes of the problems currently being experienced
and recommend the best course of action to alleviate these problems. This
report presents the findings of this analysis.
II. EXISTING SEWER COLLECTION SYSTEM
Draft
The Eastside Sewer Collection System consists of three sub -basins, which are
described in detail in the following sections starting upstream and proceeding
downstream. A map of the entire system is included in Appendix A of this
report.
A. Pump Station #3 Sub -basin - The first sub -basin includes approximately
10,400 linear feet of 15-inch and 990 feet of 10-inch gravity outfall and
serves the portion of the County to the north of Marshville, as well as the
Town of Marshville and Pilgrims Pride. The flow from this entire area is
collected and transported to Pump Station #3. From here, it is pumped to
sub -basin #2 via approximately 17,400 linear feet of 12-inch ductile iron
force main. Pump Station #3 contains duplex pumps, capable of pumping
750 gallons per minute (gpm) each or 950 gpm while operating
simultaneously.
The majority of the -flow from the Town of Marshville enters the County's
outfall system at a metering station on the North Side of Town near Buck
6 of 19

Branch Creek. A small portion of the Town's system, referred to as
Marshville West, enters the outfall system at a metering station on the
west side of Town near Highway 74. The flow from Pilgrims Pride also
enters the outfall system on the west side of Marshville.
B. Pump Station #2 Sub -basin — The second sub -basin includes
approximately 350 linear feet of 18-inch and 9,200 feet of 15-inch gravity
outfall serving the area of the County on the northwest side of Wingate, as
well as the Town of Wingate itself. The flow from this subsystem, and
that from Sub -basin #3, is collected and transported to Pump Station #2.
From there, it is pumped to Sub -basin #1 via approximately 5,700 linear
feet of 12-inch ductile iron force main. Pump Station #2 contains duplex
pumps, capable of pumping 1,100 gpm each or 1,800 gpm pumping
simultaneously.
C. Pump Station #1 Sub -basin — The third sub -basin includes
approximately 3,600 linear feet of 15-inch gravity outfall and serves a
portion of the County on the northwest side of the Town of Wingate. The
flow from this sub -basin, along with that from Sub -basins 2 and 3, is
collected and transported to Pump Station #1. From there, it is pumped to
the City of Monroe's Wastewater Treatment Plant via approximately
4,900 feet of 14-inch force main. Pump Station #1 contains duplex
submersible pumps, capable of pumping 1,800 gpm each or 2,465gpm
pumping simultaneously.
III. SYSTEM FLOW DATA
Draft
In order to investigate the cause or causes of the problems being experienced
by the Eastside Collection System, several different types of data were
obtained. First, daily meter readings were obtained from each of the seven
permanent metering stations within the Eastside system for the period from
January through July of 2003. This data is located in Appendix B. Second,
electronic, data -logging flow meters were installed at key points within the
system to evaluate the instantaneous flow rates from different parts of the
system under various conditions. Electronic flow meter data is located in
Appendix C. These are discussed in detail in the following section.
A. Permanent Metering Devices
Within the Eastside system, Union County utilizes 4 permanent meters for
billing purposes and 3 permanent meters to monitor flow in Pump Stations
#1, #2, and #3. The permanent billing meters record flow from the
Marshville outfall, Pilgrims Pride, Marshville West, and Wingate.
1. Marshville Metering Station — Wastewater from the majority of the
Town of Marshville is metered through an 8-inch Palmer-Bowlus
7of19

Draft
flume. An ultrasonic transducer measures the depth of flow and
calculates flow rate. The meter measures flow rate between 14 and
310 gpm (20,160 to 446,400 gpd).
2. Marshville West Metering Station — Marshville West's wastewater
flow is also metered through an 8-inch Palmer-Bowlus flume. The
meter uses an ultrasonic transducer to measure depth of flow and
calculated flow rate. The meter best measures flow between 14 to 310
gpm (20,160 to 446,400 gpd).
2. Pilgrims Pride Metering Station — Wastewater flow from Pilgrims
Pride is monitored by a 12-inch Palmer-Bowlus flume and depth
measured by a ultrasonic level transducer. The acceptable
measurement range is between 31 to 752 gpm or 44,640 to 1,082,880
gpd.
4. Wingate Metering Station — Wingate's wastewater flow is monitored
through a 15-inch Palmer-Bowlus flume and depth measured by an
ultrasonic transducer. The acceptable flow range for his meter is 49 to
1,385 gpm (70,560 to 1,994,400 gpd) .
5. Pump Station #1 Metering Station — Flow through Pump Station #1
is measured by a Mag Meter. The Mag meter is located on the
discharge side of the pump station. The flow is recorded with a
totalizer and periodically read and recorded in hard copy form.
6. Pump Station #2 Metering Station — Flow through Pump Station #2
is measured by a Mag Meter. The Mag meter is located on the
discharge side of the pump station. The flow is recorded with a
totalizer and periodically read and recorded in hard copy form.
7. Pump Station #3 Metering Station — Flow through Pump Station #3
is measured by a Mag Meter. The Mag meter is located on the
discharge side of the pump station. The flow is recorded with a
totalizer and periodically read and recorded in hard copy form.
B. Temporary Metering Devices
Seven electronic flow meters were used to monitor the instantaneous flow
in the system during this investigation. Meter locations were selected to
isolate flow coming from Marshville, Pilgrims Pride, Wingate and the
County lines in order to effectively investigate the system.
The electronic flow meters operate using the continuity equation, which
states that the average velocity of a liquid passing through a pipe times the
cross -sectional area of flow equals the rate of flow. The data is

continuously gathered and averaged in 15-minute increments and stored in
the meter. Hydrostructures, P.A. technicians periodically visited each site
(approximately once per week or after every major rain event) to
download the data and evaluate and/or calibrate the meters.
1. Flow Meter #1 - Meter 1 was located in the old Buck Branch
Monitoring Station on Marshville's outfall at the County tie in. Flow
Meter #1 measured flow entering the Marshville Outfall downstream
of the Town's permanent meter and Flow Meter #3. There is
approximately 4,900 feet of outfall between Flow Meter #1 and Flow
Meter #3 along Buck Branch. Because the outfall follows the run of
the Branch, we suspected that the outfall would experience some
inflow/infiltration during a rain event. Therefore, Flow Meter #1 was
located in a position to measure the extraneous flow entering the
system along this outfall.
2. Flow Meter #2 - Flow Meter #2 monitored the flow in the County
outfall from Pilgrims Pride and Marshville West. Flow Meter #2
checked the quantity of flow recorded by the Pilgrims Pride and
Marshville West and measured flow entering the County's outfall
between these connections and Pump Station #3.
3. Flow Meter #3 - Flow Meter #3, located in the manhole directly
downstream of the Marshville Metering Station, measured flow
coming downstream out of the new Marshville Monitoring Station.
The primary reason for placing Flow Meter #3 at this location was to
check the accuracy of the permanent flow meter during high flow
conditions. Also, it monitored he amount of I/I entering the
Marshville outfall downstream of the permanent Marshville metering
station.
4. Flow Meter #4 - Flow Meter #4 was located on the County's outfall
upstream of Pump Station 2. Flow Meter #4 monitored flow between
Pump Station 3 and Pump Station 2 to calculate the volume of
extraneous flow (1/1) entering the County outfall between to two pump
stations.
5. Flow Meter #5 — Flow Meter #5 was located on Wingate's outfall
downstream of the Wingate Metering Station. At this location, Flow
Meter #5 measured the combined flow from both of the Wingate
outfalls and checked the accuracy of the Wingate Meter. The meter
was also located downstream of the Wingate Permanent Metering
Station in order to determine the sequence of surcharge. This
sequence will help determine the contributors to the surcharge
problems at Pump Station #2 and Wingate's Metering Staion.

6. Flow Meter #6 — Flow Meter #6 measured flow upstream of the
Wingate Permanent Metering Station. This location allowed the flow
from Wingate to be measured and compared with the recorded flow at
the town's meter. Also at this location, the metering station was
monitored on both sides by Flow Meter #5 and Flow Meter #6 to
determine the sequence of surcharge.
7. Flow Meter #7 — Flow Meter #7 was located in manhole #MB 11 on
Wingate's outfall. The purpose of this location was to monitor flow
from the Halfway Branch outfall.
IV. EVALUATION OF PROBLEMS
This section evaluates each of the three major problems with the Eastside
collection system identified in Section I of his report.
A. Frequent Sanitary Sewer Overflows (SSO's) during rain events
The United States Environmental Protection Agency (EPA) and the North
Carolina Division of Water Quality have both established guidelines that
call for the elimination of SSO's in sewer collection systems. Union
County has also set this as a goal. Unfortunately, the Eastside system has
experienced a number of overflows this year as indicated in the following

se 20 spills released a total of more than 2 million gallons of untreated
wastewater into the environment. This is unacceptable to the County and
the regulatory agencies.
Capacity Issues
The Eastside collection system is under capacity to handle the allocated
flow from the Town of Wingate, Town of Marshville, and Pilgrams Pride.
According to the Contract between the County and the Town of
Marshville, the Town is allocated 376,000 gallon per day of wastewater
capacity on a monthly average with a peak flow rate of 490,000 gallons.
Pilgrams Pride is allocated 950,000 gallons per day (on a 24-hour average)
through its pre-treatment agreement with the City of Monroe. The
Contract between the County and the Town of Wingate allows a peak flow
rate of 646,780 gallons per day from the Town. Neither of these contracts
defines "peak flow", which is typical terminology to define instantaneous
or short-lived peaks. The nature of the discharge method used by
Marshville and Pilgrims Pride allow the "peak flow" to be a long,
sustained peak. The combined "peak flow" of these three contracts is
2,086,780 gpd.
The City of Monroe allocates 1,950,000 gpd of treatment capacity to
Union County via a contract between the two local government entities.
The County has allocated a peak flow of 2,086,780 gpd to Marshville,
Wingate and Pilgrim's Pride. Should these discharging entities maintain
peak flow for sustained periods, the combined flow from these entities
alone would exceed Union County's allocated capacity in the Monroe
WWTP.
Furthermore, when the Towns and Pilgrams Pride is supplying wastewater
at their peak allocated flow, the County leaves no capacity for its own
flow. The City of Monroe bills Union County at a higher rate when the
flow exceeds the Contract amount. The extra cost for Union County is not
incurred on the Towns or Pilgrams Pride.
Union County acknowledged the problem with allocated capacity and
made efforts to remedy the situation. In 1999 the City of Monroe and
Union County partnered in a plan to upgrade the Monroe WWTP to create
more treatment capacity, which would allow Union County additional
capacity. After the engineering was completed but before construction of
the upgrade project began, Wampler Foods (now Pilgrims Pride) indicated
to Union County that they would divert their wastewater to a proposed
new wastewater treatment facility by spring of 2002 (the proposed
Sheaffer system). A letter from Wampler Foods to the County on
February 14, 2000 stated,
11 of 19

Draft
"We are planning on the potable water to be available in the
spring of 2002 which is the same time we are scheduled to
move to the Sheaffer system. The pipeline capacity, which we
were using, will give Union County the growth potential they
are looking for without any new capital money."
Marshville also intended to join the Sheaffer system with Wampler Foods.
Taking this proposal on faith, the upgrade project was put on hold since
the added treatment capacity at the Monroe WWTP would not be
necessary. Unfortunately, the Sheaffer system project never developed,
leaving Union County with increasing capacity issues and no progress
toward capacity expansion.
The Eastside collection system is in a difficult position, because not only
is the system under capacity to handle the allocated peak flow, it is nearly
at capacity to handle peak dry weather flow. For example, the current
pumping capacity of Pump Station #3 is approximately 750 gpm
(1,080,000 gpd) with one pump running and 950 gpm (1,350,000 gpd)
with both pumps running The total average peak daily flows from
Pilgrams Pride (750,000 gpd), Marshville (300,000 gpd) and Marshville
West (25,000 gpd) requires one pump to cycle continuously just to meet
demand. The meter on the pump discharge for Pump Station #3 confirms
this. This peak daily flow is not the peak flow that is normally discussed
in municipal wastewater analyses. A typical diurnal peak occurs in
morning and afternoon cycles and last from one to three hours. Due to the
discharge methods employed at the wastewater lagoons of Pilgrim's Pride
and Marshville, the time of day and duration of the peak flow is dependent
on the operation of the facility. Therefore, depending on the daily
operating conditions, the peak flow may last hours if not days.
Also, the peak allocated flow rate from Pilgrams Pride (950,000 gpd) and
the Town of Marshville (490,000 gpd) totals to 1,440,000 gallons per day
which exceeds the pump station capacity. At a sustained combined
average daily peak flow from Pilgrims Pride, Marshville and Marshville
West, Pump Station #3 pumps continuously. State code (15A NCAC 2H
.0200) requires sewer pumping stations to provide pumping capacity 2.5
times above the average daily flow to accommodate peak flow conditions
(peak flow conditions of the typical diurnal curve, not sustained peak
flows). Under normal operating conditions (average daily flow), Pump
Station #3 operates in an acceptable range. Any flow above average
(which of course does occur even in the absence of inflow and
infiltration), would almost certainly result in surcharges or overflows.
A similar situation exists at pump station #2, which has a pumping
capacity of 1,100 gpm (1,584,000 gpd) with one pump running and 1,800
gpm (2,592,000 gpd) with both pumps running. The total average peak
12of19

••„ „. • c

Draft
daily flows from pump station #3 (1,080,000 gpd) and Wingate (320,000
gpd) and Union County (120,000 gpd) require at least one pump to cycle
continuously and at times a second pump must cycle to meet demand.
With the allocated flow from Wingate at 647,780 gpd and the maximum
discharge rate of 1,350,000 gpd from Pump Station #3, there appears to be
approximately 595,220 gpd of capacity at Pump Station #2 while running
both pumps.
Excessive I/I
With the Eastside system barely meeting the daily dry weather flow
demand, the system has little capacity for excess flow from wet weather
events. Periods of wet weather, such as those experienced this year, result
in large volumes of extraneous rainwater and groundwater entering the
collection system through defects in the pipes, manholes, and service
connections. This extraneous flow is referred to as inflow and infiltration
(1/I). When the total of average daily wastewater flow plus I/1 exceeds the
capacity of the system, the surplus exits the system as an SSO.
To evaluate the effect of wet weather conditions on the Eastside
Collection System, we utilized data from a rain event on May 22, 2003,
when a total of 1.8 inches of precipitation fell over a 24-hour period. The
instantaneous data from the temporary flow meters during this event were
compared with dry weather data to estimate the quantity of 1/1 entering the
system. Because of the rapid surcharge in the majority of these locations,
all data should be considered approximate.
The following section presents the analysis of extraneous flow on a sub -
basin by sub -basin basis:
Pun* Station #3 Sub -basin
Our analysis of the data indicates that there are a number of major
contributors of extraneous flow in the Pump Station #3 Sub -basin:
1. Marshville Outfall — According to our data, approximately 250,000
gallons of U1 entered this line between Flow Meters #1 and #3. This
occurred in only approximately 4,800 feet of line, indicating that
significant problems exist in this area. Furthermore, because the I/I enters
the system downstream of Marshville's permanent meter this flow is un-
metered by the County.
2. Marshville Collection System — Flow Meter #3 indicated that
approximately 680,000 gallons of I/1 entered the Marshville collection
system during this event. Because a large portion of Marshville's system is
collected in a lagoon and then pumped to the gravity outfall, the total
13 of 19

Draft
amount and peak of the extraneous flow conveyed to the County is limited
by the lagoon's pump capacity. For this reason we feel that the majority of
the I/I measured during this study is entering the system from the portion
of Marshville's collection system that gravity flows to the outfall and not
to the lagoon. According to information provided by the Town's staff,
Marshville's lagoon pump station is capable of pumping approximately
220,000 gpd with one pump and 360,000 gpd with two pumps. Because of
capacity issues at the station's discharge point, the Town is only able to
run both pumps during dry periods. The lagoon covers an area of
approximately 7 acres. During the rain event in question (1.8 inches),
approximately 342,000 gallons of rainwater fell directly on the lagoon.
This alone exceed the pumping capacity with one pump running.
3. Marshville West — While we did not meter this area separately the
permanent meter in the Marshville West area increased from an average
dry weather flow of 25,000 gpd to 123,000 gallons on May 22 and 80,000
gpd on May 23. This is a significant increase from a relatively small area,
indicating that problems exist in the Marshville West collection system.
4. Pilgrims Pride Lagoon — Pilgrims Pride has 2 lagoons with a total surface
area of approximately 8 acres. During the rain event on May 22,
approximately 387,000 gallons of rainwater fell directly into the lagoon.
Also, a significant area of the plant site currently drains into the lagoon,
allowing more extraneous flow into the system. Fortunately, Pilgrims
Pride was attempting to equalize during this peak, so the peak from these
lagoons came several hours after the peak from Marshville, thereby
reducing the severity of the surcharge and subsequent SSO at Pump
Station #3. However significant quantities of stormwater is entering the
system from the. Pilgrims Pride site.
5. Union County Outfall to Pump Station #3 — Subtracting the flows from
Marshville West and Pilgrams Pride, we estimate that approximately
900,000 gallons of UI entered the County Outfall upstream of the tie-in
point of the main Marshville Outfall. The instantaneous peak flow was
approximately 1,900,000 gpd.
Pump Station #2 Sub -basin
There are also major I/I contributors in the Sub -basin served by Pump Station
#2.
1. Union County Outfall to Pump Station #2 — This area was monitored by
Flow Meter #4. According to our data, approximately 1,150,000 gallons
of I/I entered this line on May 22 and 23. The instantaneous peak flow
during the rain event was approximately 2,500,000 gpd. (Note: Internal
television inspection performed as part of a recent sewer rehabilitation
14 of 19

Draft
project confirmed that portions of this line were in poor condition.
Infiltration rates observed were heavy during a relatively dry period).
2. Wingate Collection System — This area was monitored by Flow Meter
#5. According to our data, approximately 1,700,000 gallons of I/1 entered
from the Wingate System on May 22 and 23. The instantaneous peak flow
during the rain event was approximately 1,700,000 gpd.
3. Wingate Halfway Branch Outfall — This area was monitored by Flow
Meter #7. We found approximately 320,000 gallons of I/I entered the
system upstream of this meter during the May 22-23 rain event. This flow
is included in Flow Meter #5 downstream. However, the level sensor
stopped functioning late on the 22nd, so all of this extraneous flow was
recorded on the 22nd. The instantaneous peak flow during the event was
approximately 600,000 gpd
B. Surcharging of Metering Stations for Wingate and Marshville
Both Marshville and Wingate relocated their permanent metering stations
from their original locations due to surcharge conditions that existed in the
system. Unfortunately, they are still surcharging. As mentioned earlier,
the County's outfall system can barely handle the dry weather peak flows
in the area. It is quickly inundated during heavy rain events, causing the
system to surcharge very quickly.
1. Marshville Outfall Surcharge — Our temporary flow meters indicated
that any surcharges on this line were not caused by the outfall, they
were caused by the Palmer-Bowlus flume itself. The outfall line is
10-inch gravity with good slope, but the flume is only an 8-inch and
relatively level. It simply cannot handle the peak flows occurring
during wet weather periods.
2. Wingate Outfall Surcharge - There are two main issues regarding
surcharge of the Town of Wingate's outfall. First, the meter is
periodically surcharged during wet weather conditions due to limited
pumping capacity at Pump Station #2. Excess flow from both the
County and Wingate outfalls inundate the pump station causing
surcharge up both outfalls including Wingate's metering station. The
Palmer-Bowlus flume will only work during free flow conditions,
not surcharge. Based on an analysis of data from the Wingate
permanent meter, it also appears that there is periodic surcharge at
the permanent meter during dry weather conditions. This could be
caused by temporary blockages in the line or at the bar screen at
Pump Station #2 (since removed) or merely be false readings from
the meter itself.
15 of 19

Draft
The second issue involves overflows that have occurred on the
Wingate outfall upstream of the Wingate permanent metering station
near McIntyre Road. The Town thought the overflows were possibly
caused by the backup from Pump Station #2. However, data taken
from the temporary flow meters showed that the initial surcharge in
the Town's 12" outfall was caused by the flow from upstream
exceeding the capacity of the line. However, Pump Station #2 is
soon inundated causing the surcharge to worsen.Because of
surcharge conditions caused by high peak flows, the metering
stations do not function properly, causing billing disputes. These
disputes are discussed in the section C below
C. Billing Disputes between Union County and the Towns
The high peak flow rates and surcharge conditions described above not
only cause operational difficulties for the County, they also result in
frequent disagreements over billing discrepancies. The major billing
issues we discovered are:
• The Palmer-Bowlus type flume used in the permanent metering
stations do not work under surcharge or submerge conditions. Neither
do the electronics in the ultrasonic level sensors. Flow meters of this
type only measure level to calculate flow, they do not measure
velocity. For this reason there has to be free or unobstructed flow
conditions. During submerged conditions the level sensor measures
the elevated level but it is no longer free flow and the formula used to
calculate flow becomes invalid. In this situation the flow meter usually
defaults to the maximum flow setting programmed in the instrument.
Debris and solids can also foul the sensors causing false readings and
errors. Both towns relocated their permanent metering stations from
their original locations in an attempt to address the surcharge problem.
However, they still occur frequently at the Wingate metering station.
• The meter at the Wingate metering station appears to have been
programmed wrong when it was originally installed. The maximum
flow is set at "3.07" mgd. However, this number is actually the
maximum flow for this meter in cubic feet per second. The actual
maximum flow for this meter should be 1.99 mgd. Therefore,
whenever the flume defaults to the maximum flow, the Town of
Wingate is over billed for the duration of the time the flow was peaks.
In early January of 2003, this incorrect reading (3.07 mgd) was
sustained for eleven consecutive days when all other data showed that
flows should be normal. This was due to either level sensor failure or
a blockage downstream causing a surcharge condition.
16of19

• The Marshville meter does not record peak flows in excess of 0.576
mgd (400 gpm). This is the maximum flow rate for an 8" Palmer-
Bowlus flume and therefore is programmed into the meter. However,
the temporary flow meter we installed downstream of this meter
recorded an instantaneous peak flow rate of 0.80 mgd (556 gpm).
Therefore, the Town of Marshville is being under billed for any period
in which the instantaneous flow is greater than 0.576 mgd.
• Both towns exceed the maximum flow rates allowable under their
contracts with the County. Even assuming that the stated maximum is
a daily maximum and not an instantaneous maximum they both can
exceed their maximum flow during rain events. During our study
period, Marshville exceeded their contract on 2 different occasions,
and Wingate exceeded theirs on 4 occasions.
These issues should be resolved so that all of the entities involved have
confidence that they are being billed for the correct amount of flow.
V. CONCLUSIONS AND RECOMMENDATIONS
Conclusions
Draft
It is obvious that the Eastside Sewer Collection System has problems with
insufficient capacity based on the number of overflows that have been
observed this year. The system operates near its capacity during dry weather
conditions, which leaves very little capacity for extraneous flows (I/I) during
wet weather conditions. Unfortunately, all of the systems served by the
Eastside system are contributing excessive levels of I/1, which quickly
overwhelms the capacity and causes surcharging and SSO's.
The County's outfall lines are constructed of vitrified clay pipe that is
approximately 26 years old. Internal television inspections performed on the
line indicated that numerous areas of joint infiltration and cracked pipe are
present. The County started rehabilitating a portion of the outfall to Pump
Station #2 this summer, and plans to continue this rehabilitation program in
the future.
The collection systems in both Wingate and Marshville are considerably older
than the County outfall system, and both also have significant I/1 problems.
Wingate conducted a Sewer System Evaluation Study (SSES) in 1999-2000,
which was performed by Hydrostructures, P.A. Recent conversations with
Town staff indicate that they have rehabilitated manholes and repaired some
defects in collection mains. They also have budgeted for line rehabilitation.
The Town of Marshville is also involved in 1/I reduction efforts including line
replacements and manhole rehabilitation.

Draft
Recommendations
Given the County's and the regulatory agencies' stated goals of eliminating
SSO's, it is vital that steps be taken the improve the UI problems being
experienced by all of the principals in the Eastside System. Our
recommendations are as follows:
Short-term Recommendations:
• The only short-term solution for the capacity and SSO problems at
Pump Station #2 is the construction of a flow equalization structure or
structures, which will provide temporary storage for excess flow
during rain events. The stored flow can then be released back into the
system during dry low flow periods.
• Union County, the Town of Marshville and the Town of Wingate
should all aggressively continue (or start) I/1 reduction programs.
• Union County, the Town of Marshville, and Pilgrims Pride should
work cooperatively on a lagoon optimization plan that could allow the
lagoons to serve as flow equalization facilities, shaving off the high
peaks during wet weather conditions. Pumping during periods of dry
weather (when the system can handle it) provides sufficient freeboard
for rain events, allowing the lagoons to hold as much flow as possible
during rain events. Pilgrims Pride has already begun such a plan, and
this should be continued and improved where possible. A similar plan
is being developed by the Town of Marshville.
• As stated earlier in this report, a large portion of the stormwater on the
Pilgrims Pride site is diverted to the lagoons. Efforts should be made
to install mechanisms or pipes to divert flow away from the lagoons.
Similar efforts should be investigated at the Marshville lagoons.
• Renegotiate or clarify the contracts with both the Town of Marshville
and the Town of Wingate to clearly define flow allocation, particularly
maximum instantaneous flow. It was the County's intent that the peak
flow rates shown in the contracts to be maximum "instantaneous"
flow, and the outfalls and pump stations were designed accordingly.
The extremely high peak flow rates are the major causes of SSO's in
the Eastside system.
• The County and the Towns need to clarify who is responsible for
meter maintenance and up keep. This will insure the meters are
functioning properly and the billing is as accurate as possible. Also
develop better communication between the County and Towns to
notify one another when a meter is malfunctioning.
18 of 19

Draft
• Replace Marshville metering station with a flume capable of handling
high peak flow rates seen during wet weather conditions.
Long-term Recommendations:
• Union County, the Town of Marshville and the Town of Wingate
should all aggressively continue I/I reduction programs.
• Union County should request the City of Monroe to resume upgrades
to WWTP and negotiate additional treatment capacity. With the
availability of this additional treatment capacity, the County could
renovate the pump stations to meet flow requirements and comply with
State Code for sewer pumping facilities.
• Union County may consider diverting wastewater from Pump Station
#3 to Anson County or build a new regional WWTP to serve the entire
system, removing the County's reliance on the City of Monroe.

Dee,
Attached is the information related to requested permits for Union County. This identifies what
is necessary to satisfy all commitments or perceived commitments by Union County and
provide our development community the ability to maintain current business plans.
The permit modification to 3.0 MGD has been issued contingent upon CG&L's approval.
The supporting engineer report was submitted to CG&L last Friday. Phase I construction is on
schedule for March 2007 (required for operation at 3.0 MGD). Also, ahead of schedule is
the construction of the expansion to 6.0 MGD. The completion is currently scheduled for
summer of 2007. We will bring detailed schedules and review these with you on Friday.
Currently, our most evident reoccurring SSO is at 12 Mile across from the influent pump
station. This pump station is scheduled for upgrade in Phase I of the expansion construction
(March 2007), thus allowing more flow into the plant. Also a larger diameter line is designed
and will be in service prior to any additional connections being allowed by UCPW. We will
discuss this further on Friday.
Disregard my phone message from this morning. In attendance with me will be Mark Tye and
Eric Hardy. If you feel anyone else would be beneficial, please let me know.
Thank you for your consideration and I look forward to seeing you on Friday.
Christie Putnam, P.E.

THE LETTER
ithe ( Ijarlitte (Observer
County and school officials have taken issue with elements of a letter county commissioner Stony Rushing mailed to more than
1,000 county residents. Here, we contrast the letter with their responses:
THE LETTER
"Two of our new schools ... did not have sewer permits even though they are scheduled to open next month."
THE RESPONSE
The schools will open on time, officials say. The permits were initially delayed by state concerns about sewer capacity but the
problems were resolved and the schools got the permits as of June 30. Rushing's "fact-finding mission" was June 27. His letters
were postmarked last week.
THE LETTER
"Both Schools have now received permission to have Pump and Haul permits, so do not be surprised to see tanker trucks full of
raw sewage parked at the new schools."
THE RESPONSE
"Pump and haul" Is a safe, state -approved temporary method similar to using a septic tank, said Dave Burnett, Union County
Public Schools facilities director. Sewage will be collected from either a tank or manhole away from the school. The schools will
use the method until their sewer lines are complete -- as did Marvin Elementary and the new Walter Bickett Elementary.
Burnett also disputes the prospect of "raw sewage parked at the schools." "These trucks aren't just going to be hanging around
the school," he said. "They come to a site, they pump and they leave the site."
THE LETTER
"(The schools) asked for a sewer permit more than one year ago."
THE RESPONSE
The schools asked for sewer availability last year -- Kensington in July, and Sandy Ridge in November. But they couldn't ask for
permits until engineering plans were complete, said Christie Putnam, interim public works director. The permits for both schools
were submitted to the county at the end of April and forwarded to the state in a matter of days, Putnam said.
THE LETTER
"...the 192,000-sq. ft. Wal-Mart at Tom Short and Rea Rd. that Union County is fighting in court does have a sewer permit."
THE RESPONSE
http://www.charlotte.com/mid/observer/news/local/states/north caroling/counties/union/12152460.... 7/19/2005

.THE LETTER Page 2 of 2
True, but Wai-Mart's sewage will be processed in neighboring Mecklenburg County because of drainage patterns and won't tax
Union County sewer capacity. It's not a matter of Union County preferring Wal-Mart over the schools, Putnam said.
THE LETTER
The county is "helping WaI-Mart," and its court fight against the proposed supercenter is "phony."
IN REALITY
Sewer permitting is separate from the county's -- and residents' -- court fight against Wal-Mart, which is a land use issue.
Issuing sewer availability is routine, as long as the capacity is available, and does not constitute "helping" Wal-Mart, Putnam
said. "We don't have a dog in that fight," she said. The court battle is continuing.

OBSERVER EXCLUSIVE
Rushing's letter on Wal-Mart stirs anger, rebuttals
Shalati among those who say commissioner is creating confusion
JEN ARONOFF
Staff Writer
i;(acebarlattc Observer
County officials and residents of a western Union County neighborhood say they are offended by a county commissioner's letter
that implies the county favored a proposed WaI-Mart over schools.
Homeowners in western Union County opened their mailboxes late last week to find a letter from commissioner Stony Rushing.
It implied the county favored the disputed Wal-Mart with a sewer permit while Kensington and Sandy Ridge elementary schools,
set to open next month, went without.
It begins "Union County is Spending Thousands of Dollars to fight Wal-Mart in court, so...Why is Union County helping Wal-
Mart?"
The letter describes supposed sewer woes, and chastises County Manager Mike Shalati, the county's public works department,
and three county commissioners and "their political supporters."
Rushing defended his letter, which he said he mailed to more than 1,000 homes last week. It is particularly directed at the
Hunter Oaks and Somerset subdivisions, near the site of the proposed Wal-Mart at Tom Short and Rea Roads.
Residents from those neighborhoods have opposed the WaI-Mart for more than three and a half years, and are now fighting it in
Court with support from the county.
A slightly different version of the letter was sent to some local elected officials.
Friday, Rushing said the Observer should focus on the concerns raised in the letter, not the letter itself. "The story is not Stony
Rushing," he said.
But county officials, school officials and residents who have long opposed the Wal-Mart disagreed, sometimes angrily, They said
Rushing's letter is politically motivated, deliberately misleading and marked by scare tactics.
"He's really doing damage to Union County," said County Manager Mike Shalati. "They are playing with our citizens. This is just
so unfortunate."
In the letter, Rushing says that he, commissioner Kevin Pressley and former commissioner Clayton Loflin -- Rushing's close
political ally and a major critic of Shalati -- traveled to Mooresville to meet with state environmental officials to learn more about
sewer issues in the county.
"What we found out is unbelievable," the letter says.
State officials, however, say that although Union County has faced some violations this year, its situation is not far out of the
ordinary.
Rushing dismissed allegations that the letter is misleading, and said no one is challenging the facts he presents.
"I can't write everything," he said. "If I didn't write 'Moses parted the Red Sea' in there, that doesn't mean it was a lie. There's
nothing misleading about what I put in that letter."
Others said the problem is not the facts in the letter -- but what was left out. Shalati criticized Rushing for "getting pieces of
information from here and there ... mixing and intentional confusion."
Residents who have actively opposed the Wal-Mart said Rushing was using two of western Union's most potent issues, schools
and Wal-Mart, to confuse and divide their neighborhoods.

Rushing's letter on Wal-Mart stirs anger, rebuttals
Page 2 of 2
"It's just so typical of what we have seen out of Mr. Rushing in the past," said Hu&terQaks resident Jeff Kravis,}kho has helped
lead the fight against Wal-Mart. "He leads people astray rather than trying to inform them "—'—
If Rushing had really wanted to "do something good," Kravis said, he should have contacted Wal-Mart opponents before sending
out a letter.
The commissioners who have listened to Wal-Mart opponents' concerns, Kravis said, are the ones Rushing assails in his letter --
Richard Stone, Hughie Sexton and Roger Lane.
Another Wal-Mart critic, Ginger Leppert of Somerset, said she returned from Myrtle Beach to find the letter in her mailbox. She
said it struck her as politically motivated and made it appear that the schools were facing a crisis and the WaI-Mart project was
moving forward. She says talking with her neighbors helped her straighten out the facts.
"The thought of sewage trucks in the parking lot with our children is quite overwhelming, but that's not at all the case,
apparently," She said.
Indeed, the schools have all necessary permits and will open on schedule, said Dave Burnett, Union County Public Schools
facilities director.
In the letter, Rushing repeated his call for an investigation of the county's public works department.
Interim Public Works Director Christie Putnam called Rushing's frequent attacks "a little disheartening" and "bad for staff
morale."
"There's a lot of man hours spent on these kind of issues that could be spent otherwise," she said. "Everyone on the staff is kind
of used to it now. They know they're doing a good job, the right thing."

Good afternoon to all. Mr. Hilligoss, Mr. and Mrs. Marryat and Mr. Dreier you have all sent me a -mails
within the last few days requesting an update on the odor issues being experienced in the Quellin
neighborhood. After many man-hours of investigation UCPW has confirmed the odors are in fact
coming from the Twelve Mile Creek Wastewater Treatment Plant (WWTP). The primary source of odors
is the aerobic digesters where biosolids (a by-product of the biological treatment process) are stabilized
prior to their application to farm land as fertilizer. A secondary source of odors is the influent lift station
and primary treatment facility where raw wastewater is introduced into the treatment works. UCPW has
exhausted all practical short term options to eliminate/reduce/control the odors.
Typically there is a distinct absence of odors at the Twelve Mile Creek WWTP proper and it's immediate
boundaries. UCPW suspects that a combination of temperature, humidity and wind direction are causing
odors to be held near the ground, concentrated in low areas and migrate off site. The extremely close
proximity (approximately 1 football field from the actual treatment units) of Quellin to the WWTP
compounds the situation.
The actual process to permit and design the ongoing WWTP expansion officially began in January
2002. Since that time automated air scrubbing units at the influent lift station and primary treatment
facility (where raw wastewater is introduced to the facility as previously mentioned) have been a part of
the expansion plans. Air scrubbing units at these key locations continues to be a part of the current
expansion. Contractually they do not have to be operational before the summer of 2008. The activation
of these units may help the situation in Quellin, but, as previously mentioned the primary odor source
has been identified as the aerobic digesters.
Given the fact that the aerobic digesters have been identified as the primary source of odors, your
neighborhood could possibly see substantial improvement with respect to odors if they were covered
and the vented air scrubbed. A project to do just this is already identified in Union County Public Works'
Capital Improvement Plan. However, please note that the Plan has NOT yet been approved by the
Union County Board of Commissioners. If the Project was currently approved and we started work this
week it would still be approximately 2 years before the project could be designed, permitted, placed out
for bid, a contract executed, components delivered, constructed and placed in service.
With all this being said, I must revert back to the previous statement that UCPW has exhausted all
practical short term options to eliminate/reduce/control the odors. UCPW is well aware of neighborhood
concerns, and as mentioned herein, has long term plans to address the situation. Staff is willing to
attend one of your HOA meetings and do our best to answer questions if the neighborhood so desires.

Hello Mr. Robson,
Mr. Rex Gleason, regional supervisor for surface water protection at our
Mooresville Regional Office, asked that I respond to your inquiry about the odor
concerns in the Quellin subdivision in Waxhaw.
Inspectors from our Mooresville Regional Office have visited the Twelve Mile Creek
Wastewater Treatment Plant and have worked with plant staff in an attempt to assess
the presence of the odor, the cause and possible solutions to the problem.
Plant staff have jet cleaned and inspected the sewer lines, replaced one air relief
valve, and added sodium hydroxide to further eliminate possible causes of odors.
Mark Tye, Assistant Public Works Director for Union County has concluded that the
odor is coming from the aerobic digesters where biosolids are stabilized prior to
their application to farmland as fertilizer. A secondary source of the odor is the
influent pump station and primary treatment facility where raw wastewater is
introduced to the treatment works.
Union County Public Works staff suspects that a combination of temperature,
humidity and wind direction are causing odors to be held close to the ground,
concentrate in low areas and migrate off -site. Division staff agrees with this
assessment and has seen similar conditions in other areas of the state affect other
WWTPs. The Quellin subdivision's location, approximately one football field from
the actual treatment units, compounds the situation, as has the recent removal of a
buffer of trees for a county road project located between the plant and the
neighborhood.
My understanding is that a capital improvement plan proposal to implement plant
improvements that would cover the aerobic digesters and scrub the vented air was
recently voted down by the Union County Board of Commissioners. Should, however,
this plan be approved today, it would still be approximately two years before the
improvements went through all phases of design and construction.
The best -run sewage treatment plants have a characteristic odor as a by-product of
their function. No health advisories have been issued due to the odors from the
plant. Within certain engineering parameters, odors associated with sewage
treatment can be reduced and even be generally absent. However, with the weather
conditions and topography in North Carolina and land use decisions that enable
housing in close proximity to a wastewater facility, conflict, such as this one,
can arise.
Should you have additional questions, please contact me at:

Mr. Tye:
Today is Tuesday, and the odor is worse than ever! This is becoming quite difficult. The odor is offensive and
cannot be healthy. Our children play outside, and this odor makes it impossible to do so.
This smell is a recent development. We moved in the area in December of 2004, and have not had this
problem until recently. Something has happened to cause this problem.
Please let us know: 1) What has happened to cause this problem, and 2) what is being done to resolve it and 3)
what health risks could potentially arise from the unhealthy air.
We understand your position, but we ask that you also appreciate the frustration of the residents who have to
endure this problem who cannot even go outside our homes due to this offensive odor.

Ms. Dellinger, Public Works staff was able to "experience" the odor over the weekend. We have previously
added odor control chemicals to the sewer collection system. Today we have begun modifying one of our
standard operating procedures at the watewater treatment plant. We are hopeful that the combination of efforts
will put us on the right track and that improvement will be noticed as early as today.

Dear Mr.Tye,
My husband and I also tried to sit on our deck on the evening of June 8th and experienced the terrible odor. We
also experienced it on June 9th around 9:00 pm and then again on June 10th at 7:00 am. We are embarrassed
to think of having friends over to enjoy our deck not knowing when the smell might be in the air. I have also
asked others in the neighborhood if they have smelled it and they get a soured look of their faces and say,
"yes".
To say that there are no obvious problems is just not so.

Mr. Roach, Public Works has spent many man-hours recently chasing this odor problem. There are no obvious
problems that we have been able to pin point - there have been no major changes in the operation of the
collection system or Wastewater Treatment Plant in the recent past. The problem seems to be isolated. Some
people we have interviewed in the area have not experienced any odor problems.
Unfortunately I was not here at 8:30 PM to get your e-mail. Public Works has placed a man "on -call". He is
available 24/7 and can be reached by calling 704 289-1591. Please call this number for after hours problems
and someone will promptly come out and try to pin point the source of the problem. Please keep in mind that
the people that answer the phone and the people that come out to investigate are only trying to help resolve the

GOV. EASLEY ACTIVATES STATE EMERGENCY RESPONSE TEAM
Urges Caution As Severe Storms Move Through The State
RALEIGH — Gov. Mike Easley today activated the State Emergency Response Team and dispatched
emergency crews to assist affected counties as severe storms move across the state. The governor
urged citizens to pay close attention to weather reports for the rest of the day and take immediate action
if a tornado warning is issued for their area. Fatalities and damage have already been reported in North
Carolina.
"This storm system has the potential to cause more tornados during the day and isolated flooding in our
state," Easley said. "I urge everyone to stay tuned to local weather forecasts, heed the advice of local
emergency officials and have a plan of action in case a tornado develops to keep their family safe."
Several people were reported dead and dozens of homes were destroyed early this morning when what
appears to have been a tornado touched down near Old Lake Road off NC 87 in the town of
Riegelwood in Columbus County in southeastern North Carolina. A shelter has been opened at the
Acme Delco Elementary School in Riegelwood.
State emergency management coordinators are already in several counties including Columbus,
Rowan, Iredell and Lincoln. The Department of Transportation reports that N.C. 87 is closed in
Columbus County from N.C. 11 to U.S. 74 due to downed trees and power lines. Traffic is being
detoured along N.C. 11 to U.S. 74.
Other reports of damage include several counties in the western part of the state. Scattered power
outages are also reported. A possible tornado touched down in east Lincoln County late last night with
trees down on houses and across roadways from South Little Egypt to Webb Road. In Iredell County
near Statesville, local emergency management officials reported three mobile homes in the area of
Fraley Road and Riverhill Road off I-40 have been destroyed, and other mobile homes in the area have
been damaged. Five people were transported to hospitals with injuries. Reports of power lines hanging
low over US 70 in Rowan County at the Iredell County line caused eastbound and westbound lanes of
the highway to be closed for an undetermined amount of time.
The system that is traveling through North Carolina today has already been responsible for damage and
fatalities in other parts of the southeastern U.S. Tornados were reported yesterday in Alabama and

Florida. A tornado watch is posted for central North Carolina until 3:00 this afternoon and severe
thunderstorm warnings have been issued for numerous counties.
A tornado watch means conditions are right for tornado formation. A tornado warning means that a
tornado has been sighted on the ground or on radar. The safest place to be during a tornado is
underground in a basement or storm cellar. If you have no basement, go to an inner hallway or smaller
inner room without windows, such as a bathroom or closet. Go to the center of the room. Try to find
something sturdy you can get under and hold onto to protect you from flying debris and/or a collapsed
roof. Use your arms to protect your head and neck.

Union County Public Works — Twelve Mile Creek WWTP
NPDES Permit NC0085359
Union County
Dear Ms. Putnam:
Enclosed, please find a copy of the Special Order by Consent (SOC) application you submitted to this
office on July 7, 2006, along with Hazen & Sawyer, PC's check number 3627 in the amount of $400.00.
These items are being returned to you because the Division. of Water Quality has reviewed the SOC
application and the materials sent in support of the application, and determined that the circumstances
they describe do not meet the criteria for which a SOC may be issued.
SOCs may only be issued when a facility's noncompliance is deemed to be due to_ some deficiency
within the design or structure of the existing wastewater treatment plant such that the facility cannot.
become consistently compliant with permit limitations until its inherent flaws are corrected. SOCs may
not be issued in situations when the circumstances that brought about the noncompliance are judged to
be operational in nature (i.e. where increased operational oversight may haveprevented the
noncompliance). Furthermore, to be considered for SOC coverage, the applicant must be able to prove
it has optimized its existing treatment facilities.
Based upon our review of the application and data submitted by the facility, and from information
obtained in meetings and telephone conversations with Mooresville Regional staff, it is the Division's
belief that the facility can be substantially compliant with limits for Flow, BOD, TSS, NH3-N and Fecal
Coliform with conscientious day to day operational oversight and being prepared for events that could
disrupt efficient operation (e.g. having generators during power interruptions or an inventory of spare
parts for critical equipment).
The Division has given more attention to the issue of noncompliance as it pertains to Total Phosphorous.
Additional information has been submitted that discusses actions the facility can take in the near term
and in the future that may reduce Total Phosphorous concentrations in the effluent and loading to the
receiving stream. However, this same information indicates the facility has not followed through in
implementing some of its consulting engineer's recommendations. Most specifically, the facility does
not appear to have used its existing chemical addition facilities as a means to attempt to reduce Total
Phosphorous. For this reason, it cannot be said the Twelve Mile Creek WWTP's existing facilities have
been optimized or maximized, and therefore, SOC coverage cannot be considered. Nonrthcarolina

Subject: Response to Requested Information
Dear Mr. Bou-Ghazale,
G3 (LA
In response to your requests for additional information dated November 7 and 9, 2006,
Union County Public Works (UCPW) hereby submits the following response.
Chronic Non -Compliance Issues
The Twelve Mile Creek WWTP (12 Mile) has over the past two years had compliance
issues due to factors such as interruptions in power supply and substandard
performance of existing equipment. However, based on recent DMR's the plant has
attained substantial compliance with all permit requirements except annual average
phosphorus. Recent improvements at this facility include the addition of floating
aerators in July and the identification and replacement of the clarifier seal in mid
October. Upon review of 12 Mile's most recent DMRs, the Mooresville Regional Office
(MRO) will find this facility to be in substantial compliance with all parameters including
phosphorus. Included are the August and September DMR data sheets and a draft copy
of the October DMR.
Current Capacity
12 Mile has a current permitted capacity of 2.5 MGD. The current running annual
average for the 12 Mile facility is 2.21 MGD. The latest monthly average flow is 2.44
MGD. The current number of permitted lots for 12 Mile is approximately 20,800 lots.
There are approximately 12,700 active accounts based on billing records. Therefore the
outstanding (not "on-line") permitted lot count is approximately 8,100. This number is
being verified and should be available for your review by the end of the year.
Projected Flows
Our history shows consumer growth in the 12 Mile service area expands at a rate of
approximately 200 accounts per month. An analysis of billing records data demonstrates
the average flow within the 12 Mile service area is approximately 220 gpd per
customer. This results in a projected monthly increase of 44,000 gpd.
400 North Church St. • Monroe, North Carolina 28112-4804 • Phone: [phone] • Fax: [phone]

Flow Assessment
UCPW is currently expanding the 12 Mile facility to a treatment capacity of 6.0 MGD. In
addition UCPW is pursuing an intermediate permit modification to 3.0 MGD upon the
completion of Phase I construction of the current expansion, scheduled for March 2007.
UCPW is also moving forward with a subsequent expansion of 12 Mile to 9.0 MGD by
initiating the preparation of the engineering report. Permitting is currently scheduled to
be completed in two years.
UCPW does not expect flow from the current permits under consideration to exceed the
anticipated treatment expansion schedule. Therefore, based upon the information
provided, UCPW request consideration of the outstanding permits.
In closing, I have requested a meeting with the MRO and look forward to reviewing this
and additional forthcoming information at that time. If you have any questions, please
do not hesitate to call.

The Division of Water Quality has determined that Union County is unable to adequately collect and treat
wastewater tributary to the Twelve Mile Creek WWTP, NPDES permit number NC0085359 with regard to
phosphorous and flow limits and an excessive number of Sanitary Sewer Overflows (SSOs) near the
plant.
North Carolina General Statute 143-215.67(a) states in part, that no person subject to the
provisions of NCGS 143-215.1, 143-215.108 or 143-214.109 shall cause or allow the discharge of any
wastes to a waste -disposal system in excess of the capacity of the disposal system or which the disposal
system cannot adequately treat. Should these terms be violated, 143-215.67 (c) states a moratorium
may be imposed "on the addition of waste to a treatment works" if the treatment works is not capable of
adequately treating additional waste.
The Division of Water Quality has established that the phosphorous and flow limit violations for this plant
and excessive SSOs near the plant indicate that the system is in excess of its capacity. Therefore, Union
County is hereby placed on a sewer extension permit moratorium for their wastewater collection system
tributary to the Twelve Mile Creek WWTP effective February 7, 2007.
This moratorium will remain in effect until Union County has sufficiently demonstrated that it can
adequately collect and treat its wastewater such that the phosphorous and flow limits have been
addressed and the number of SSOs near the plant has been reduced and the County has obtained
written notification from the Division of Water Quality suspending the moratorium.
As required by NCGS 143-215.67(d), Union County shall give public notice that a moratorium will be
placed on the permitting of sewer extensions to the Twelve Mile Creek WWTP collection system within 15
days of receipt of this letter. Union County shall give public notice of the moratorium by publication of the
notice one time in a newspaper having general circulation in the county in which the treatment works is
located. The notice shall be as provided in the attached public notice. NoCarolina

PUBLIC NOTICE
SEWER MORATORIUM
UNION COUNTY
Union County Public Works will not receive sewer line extension permits for additional waste to its
collection system tributary to the Twelve Mile Creek WWTP, NPDES permit number NC0085359. Union
County is unable to adequately collect and treat wastewater with regard to phosphorous and flow limits
and an excessive number of Sanitary Sewer Overflows that have occurred near the plant. Therefore,
Union County is hereby placed on a sewer moratorium in regard to its wastewater collection system
tributary to this plant as of February 7, 2007.
On the basis of thorough staff review and application of Article 21 of Chapter 143, General Statutes
of North Carolina, Public Law 92-500 and other lawful standards and regulations, the North Carolina
Environmental Management Commission has determined that. Union County is unable

Good morning Barbara. Thank you for checking in on our comments as they relate to the
Draft Collection System Permit. I would like to take the opportunity to reiterated comments
already submitted just in case they were misdirected or otherwise did not receive full
consideration. Comments:
L• The description of our system (Page 1) is a little behind We have approx. 450 miles of
gravity, 53 miles of force main and 60 duplex stations.
are not comfortable with the Towns of Marshville and Wingate being mentioned in
the description of our system (Page 1) since we have no control over the operation and
maintenance of their system.
• Condition I (3) - Union County has no jurisdiction in incorporated areas and therefore an
"ordinance" would not be enforceable in much of our service area. However, Public
KO Works does have a Board of County Commissioner approved document entitled Union
I' c\O County Public Works Water and Sewer Extension Policy that we feel completely meets
C©C i the intent of Condition I (3). It is respectfully requested that language be
substituted/introduced into the permit that supports our existing policy.
• Condition I (3) - Our Legal Department is of the opinion that an ordinance is not the.
proper vehicle to address flows from satellite systems since the County has no
jurisdiction inside city/town limits. Limitations need to be addressed contractually. Our
current contracts with Marshville and Wingate expire in 2008. It is respectfully requested
that language be substituted/introduced to reflect these concerns.
• Please find an updated High Priority List attached.
Thank you very much for your concurrence and support of the pipe cleaning formula as well as
Compliance Dates for certain required activities.
Call if we need to discuss. Thanks again.

Re: odor in Quellin subdivision - Union Co.
to c.rA,lD.
have been no significant process changes prior to our first complaint on 5-31-06. However, OM)
based on field observations from UCPW staff, the odors in the Quellin area appear to be ry
coming form the WWTP and not the collection system. The biggest changes that have occurred P c
at 12-Mile recently are the construction of a bridge and parkway and the onset of warm
weather The construction efforts removed trees that had otherwise buffered the WWTP.
Public awareness of the facility was significantly increased. Weather patterns may be
creating an inversion layer of air that is effectively trapping the odors near the ground
where they migrate depending on wind direction. As you are aware, UCPW has modified our
solids handling and processing procedures (at a significant expense to UCPW) in an effort
to minimize any odors from being generated at the digesters. We will continue the modified
procedures (at significant expense.) in an effort to be good neighbors. Air scrubbing units
are a part of the ongoing expansion and will be installed at the influent pump station and
the headworks structure by the summer of 2008. Digester covers and scrubbers are in UCPW's
UNAPPROVED Capital Improvement Plan, but are not called for until the summer of 2008. The
Capital Improvement Plan currently lacks Board of County Commissioner approval.
Thank you for your assistance in these matters. Please do not hesitate to contact me if
additional discussion is required.

As you can see from Mark's email, the County appears to be taking an aggressive approach in
their attempt to locate and minimize any migrant odors associated with WWTP and/or
collection system operation. Unfortunately, as Mark pointed out, encroachment of
residential development and the resulting loss of vegetative buffers may only exacerbate
the problem until such time as the air scrubbers are installed. Odor complaints, such as
those received from this facility, are happening more frequently as development begins to
surround what was at one time an isolated WWTP. This Office will continue to monitor the
efforts by the County to identify and eliminate the source of migrant odors. Please advise
if you have any questions.

*Subject: **Fwd: Quellin - Fwd: odor in Quellin subdivision*
Dear Mark,
I just wanted to follow up on Sue Dreier's note... As you have probably already heard
on too many occasions, this problem has been going on close to a year, but has really
grown in intensity over the last six months. The smell in the mornings and during
the evenings is so bad that it keeps people in their homes. Last week I sent a
letter to NCDENR requesting their assistance and they asked me to poll the community
to try and help them zero in on where the oder is coming from.. In less than 24 hours
I received over 100 emails from residents who pointed to the WWTP. I have since
shared that feedback with NCDENR and it is my understanding that Barbara Sifford is
now working with you and your team.
This problem is impacting my neighbors here in Quellin who are trying to sell their
homes. I know of two residents who have been asked by their realtors to call them and
tell them when the odor has gone so that they can bring potential buyers to visit
Quellin and the residents home. Additionally, my sense is that if the problem
continues that this will have an economic impact on local developers and builders
ability to sell new lots. This morning around 8:30AM the odor was again just
unbearable and I decided to call the number that you sent to my neighbor Fred Roach
and got Union County Communications <your note with the phone number is attached
below Fred's>. I explained the situation to the county operator and she took my name,
address and phone number and stated that she would dispatch the person who was on
call for Public Works.. I waited, and waited, and waited, and waited and no one from
your team stopped by or called. Is this situation one of your offices top priorities?
Do you have all of the resources that you need to investigate and resolve this
problem?
Please advise as soon as your schedule permits.

Kyle Hilligoss

Re: odor in Quellin subdivision - Union Co.
Public Works has spent many man-hours recently chasing this odor problem. There are
no obvious problems that we have been able to pin point - there have been no major
changes in the operation of the collection system or Wastewater Treatment Plant in
the recent past. The problem seems to be isolated. Some people we have interviewed in
the area have not experienced any odor problems.
Unfortunately I was not here at 8:30 PM to get your e-mail. Public Works has placed
a man "on -call". He is available 24/7 and can be reached by calling 704 289-1591.
Please call this number for after hours problems and someone will promptly come out
and try to pin point the source of the problem. Please keep in mind that the people
that answer the phone and the people that come out to investigate are only trying to
help resolve the situation. They are not responsible for causing the problem.
Thank you.

Mark,
It is Sunday morning. I went out this morning at 7:30 and the raw sewage smell was
very strong and is still strong at 10:00. I followed the smell to the new bridge on
Cureton Pkwy between Quellin and the treatment facility. As you go up the hill (in
either direction) on the new Pkwy, the odor begins to dissipate. I do not know if
that is where the air valve was replaced or not, but something is going on by that
bridge. A lot of earth has been moved in that area. Is it possible the lines were
damaged in that area?
Thanks.

Kyle,
I have confirmed that NCDENR has been in contact with UCPW regarding the odor
complaints. In follow up,
I've learned that UCPW has completed the following items in an effort to address
everyone's concerns:
1. All sewer lines within the complaint areas have been jet cleaned. Typically, on
underloaded systems,
the conditions can turn septic and release sewer gas. Jet cleaning will help to
prevent this problem. As further
development continues, the systems will not be underloaded. 2. All sewer lines
within the immediate vicinity were inspected. One ARV (air release valve) was found
to be frozen
open and emitting a odor. This ARV valve was replaced yesterday.
3. Sodium Hydroxide has been added to the system in an effort to scour the force main
from the lift station.
As you can see, UCPW is diligently working on fixing the problem in order to
eliminate the sewer gases. We
will monitor the situation on our end for follow up. However, we have complete
confidence in UCPW's abilities
to determine the source and eliminate the odor.
Please keep me informed if the odor continues. Your patience is appreciated as
these issues are resolved.

Subject odor in Quellin subdivision
We live in Quellin and have been experiencing a very bad sewage smell. We have been
following the emails between you and our neighbors and we understand that there is a
valve that is broken that has been fixed or soon will be fixed. However, today 6/6
we had really bad odor all day. We live in the cul-de-sac on Thayer Dr. at the end
of the street. Could you please update us on what has been happening with the
problem and the repairs and why it is still so bad today and this evening? I saw
from your emails that you were skeptical that the odor was coming from the WWTP,
however this evening I walked over to the edge of the WWTP along the Cureton Parkway
and noticed a very strong odor coming from the last tank area. If it was that tank,
it was black in color and appeared to be having work done on it. I also heard what
sounded like leaking. Is that tank leaking sewage? The tanks next to it were
running so it is possible the smell was coming from one of them. Is there someone
who is on site during the evenings who walks around the entire plant who can verify
this?
I also walked the area between the WWTP and the creek that runs behind Thayer and
passed by a couple of manholes. I assume those are the manholes that you sealed
while work is done to correct the valve problem. I did not notice any smell from the
two manhole covers I passed which were the two closest to the end of Thayer. Could
you continue your investigation and let us know what you find?

Barbara,
Here is a response I plan to send to Coleen and Alan regarding the Twelve Mile Creek
odors. Look it over and add any comments/corrections you see fit. Return to me ASAP.
Mike
Coleen/Alan:
Last week Barbara Sifford with the MRO conducted an inspection at Union County's Twelve
Mile Creek WWTP in an attempt to ascertain the source of the migrant odors that area
residents have complained about. Accompanied by County staff, Barbara visited not only
the WWTP, but areas of the WWTP's collection system. Although Barbara did not detect
significant or unusual odors during her visit, observations made during her visit may shed
some light on the origination of the odors, why the Division may be getting so many
complaints, and the efforts underway to manage them.
Barbara noted that nearby residential development (including the subject Quellin
subdivision where most of the odor complaints have originated) has encroached to within
100 yards of the WWTP. Specifically, the influent pump station and associated aerobic
digesters are literally a "stones throw" from the nearest Quellin residences. Barbara
also noted that additional land was in the process being cleared and graded for new
residential development adjacent to the WWTP. According to County staff, this land
clearing has removed a number of trees that previously acted as a visual buffer of the
WWTP, and may have also aided in reducing migrant odors. At the time of Barbara's visit,
there was a significant amount of construction underway at the WWTP in conjunction with a
plant expansion, however, Barbara indicated that the WWTP appeared to be functioning
properly with no unusual odors detected at any point in the treatment process. According
to County staff, sewers have been cleaned and chemicals have been added in an attempt to
correct the problem, however, odor complaints continue to come in despite efforts of the
County staff.
The email I've attached below includes a June 20th update from Mark Tye as to their
ongoing efforts to identify and manage the migrant odors:

Good afternoon Barbara. UCPW had staff on -site at the 12 Mile WWTP from 9:00 PM until
12:00 PM this past Friday and Saturday (16th & 17th). Staff stayed on the move between the
WWTP, the Cureton Parkway bridge and the Quellin neighborhood.
6-16-06 Slight odors associated with the influent structure and digesters were
intermittently noted between 9:00 and midnight. Staff spoke to a number of people in
Quellin. Staff's opinion was that Quellin residents were "glad to see us out".
6-17-06 No odors were noted away from the WWTP. Slight odors were observed near the
barscreen and digesters.

residents).
Barbara, as we discussed during your visit on the 16th, 12 Mile is running good and there
have been no significant process changes prior to our first complaint on 5-31-06.
However, based on field observations from UCPW staff, the odors in the Quellin area appear
to be coming form the WWTP and not the collection system. The biggest changes that have
occurred at 12-Mile recently are the construction of a bridge and parkway and the onset of
warm weather The construction efforts removed trees that had otherwise buffered the
WWTP. Public awareness of the facility was significantly increased. Weather patterns may
be creating an inversion layer of air that is effectively trapping the odors near the
ground where they migrate depending on wind direction. As you are aware, UCPW has modified
our solids handling and processing procedures (at a significant expense to UCPW) in an
effort to minimize any odors from being generated at the digesters. We will continue the
modified procedures (at significant expense) in an effort to be good neighbors. Air
scrubbing units are a part of the ongoing expansion and will be installed at the influent
pump station and the headworks structure by the summer of 2008. Digester covers and
scrubbers are in UCPW's UNAPPROVED Capital Improvement Plan, but are not called for until
the summer of 2008. The Capital Improvement Plan currently lacks Board of County
Commissioner approval.
Thank you for your assistance in these matters. Please do not hesitate to contact me if
additional discussion is required.

As you can see from Mark's email, the County appears to be taking an aggressive approach
in their attempt to locate and minimize any migrant odors associated with WWTP and/or
collection system operation. Unfortunately, as Mark pointed out, encroachment of
residential development and the resulting loss of vegetative buffers may only exacerbate
the problem until such time as the air scrubbers are installed. Odor complaints, such as
those received from this facility, are happening more frequently as development begins to
surround what was at one time an isolated WWTP. This Office will continue to monitor the
efforts by the County to identify and eliminate the source of migrant odors. Please
advise if you have any questions.

Kyle - I contacted our regional office Surface Water Supervisor Rex Gleason (in
Mooresville) to see if anyone in his program had been contacted or were aware of the
problem. The region was contacted last week and has been in touch with the Union County
Public Works officials about the complaints and plans to perform a site visit this week
(likely Thursday or Friday after Hurricane/Tropical Storm Alberto passes through).
Mike Parker and Barbara Sifford are the staff that have been most directly involved.

Thank you for helping to address the Odor issue in Quellin. I live there now, and
just signed a contract to build a 650k home in Cureton. Just wanted to let you know
that *the odor was (is) horrible this evening*. Particularly concerning is that I
live way over on Denholme. We appreciate all that you can do because we are
seriously considering pulling out of our contract to build (just signed, nothing
done by the builder yet). I'm sure the smell reaches our new site because it is
right behind Quellin. Let me know if there is anything I can do to help resolve the
issue. Thanks so much.

Dear Mark,
I just wanted to follow up on Sue Dreier's note... As you have probably already
heard on too many occasions, this problem has been going on close to a year, but has
really grown in intensity over the last six months. The smell in the mornings and
during the evenings is so bad that it keeps people in their homes. Last week I
sent a letter to NCDENR requesting their assistance and they asked me to poll the
community to try and help them zero in on where the oder is coming from.. In less
than 24 hours I received over 100 emails from residents who pointed to the WWTP. I
have since shared that feedback with NCDENR and it is my understanding that Barbara
Sifford is now working with you and your team.
This problem is impacting my neighbors here in Quellin who are trying to sell their
homes. I know of two residents who have been asked by their realtors to call them
and tell them when the odor has gone so that they can bring potential buyers to
visit Quellin and the residents home. Additionally, my sense is that if the problem
continues that this will have an economic impact on local developers and builders
ability to sell new lots. This morning around 8:30AM the odor was again just
unbearable and I decided to call the number that you sent to my neighbor Fred Roach
and got Union County Communications <your note with the phone number is attached
below Fred's>. I explained the situation to the county operator and she took my
name, address and phone number and stated that she would dispatch the person who was
on call for Public Works.. I waited, and waited, and waited, and waited and no one
from your team stopped by or called. Is this situation one of your offices top
priorities? Do you have all of the resources that you need to investigate and
resolve this problem?
Please advise as soon as your schedule permits.
Regards,
Kyle Hilligoss

I am disappointed to hear that the problems at Quellin persist. Based on feedback
from a couple of your neighbors I was hopeful the situation had been resolved. The
faulty valve was replaced yesterday. The new valve was tested and found to be
operating correctly. Our crews are in area already this morning. We will continue to
investigate.
The tank that is "black" in color is under construction - it is new - and has not
yet been placed in service.
The tanks you are referring to are not leaking and do not hold sewage.
Mr. Marryat, as I mentioned earlier I am disappointed that a problem persist and
will continue to investigate. Please be aware however, that all property located
on the east side of the Cureton Parkway bridge (Cureton Parkway and the Wastewater
Treatment Plant) is considered a construction zone. For your own safety this
property is off limits and therefore the barriers and temporary fencing.
Trespassers caught on the property after hours will be asked to leave and will be
escorted off the construction site if necessary. If you feel compelled to visit the
facility please do so during normal business hours, with a County escort and wearing
proper protective equipment.
Thank you.

Subject odor in Quellin subdivision
We live in Quellin and have been experiencing a very bad sewage smell. We have been
following the emails between you and our neighbors and we understand that there is a
valve that is broken that has been fixed or soon will be fixed. However, today 6/6
we had really bad odor all day. We live in the cul-de-sac on Thayer Dr. at the end
of the street. Could you please update us on what has been happening with the
problem and the repairs and why it is still so bad today and this evening? I saw
from your emails that you were skeptical that the odor was coming from the WWTP,
however this evening I walked over to the edge of the WWTP along the Cureton Parkway
and noticed a very strong odor coming from the last tank area. If it was that tank,
it was black in color and appeared to be having work done on it. I also heard what
sounded like leaking. Is that tank leaking sewage? The tanks next to it were
running so it is possible the smell was coming from one of them. Is there someone
who is on site during the evenings who walks around the entire plant who can verify

Good morning Mark,
fyi - attached below is a note that one of our residents sent to Sean Calloway last
night that is yet another example of the economic impact of this problem. Also, I
sent out a poll note to the community last night around 10:30.. As of this morning
I have received 41 notes from residents who confirm that the odor was present all
weekend and the overwhelming majority of these responses point to the WWTP.. I also
received 2 notes from people who could not detect the odor (both lived on the
opposite side of the community on Blackburn Drive) and 1 note from a resident who is
out of town...

Hello Sean,
Will do..
In the mean time, there is something that you may be able to do for the residents of
Quellin:
As you may already be aware, this problem has been going on close to a year, but has
really grown in intensity over the last six months. The smell in the mornings and
during the evenings is so bad that it keeps people in their homes. Last week I
sent a letter to NCDENR requesting their assistance and they asked me to poll the

have since shared that feedback with NCDENR and it is my understanding that they are
now working with Mark Tye.
My sense is that if the problem continues that this could have an economic impact on
your firm and your builders ability to sell lots. Can you please find out if David
Guy would be willing to contact Town and County officials to ensure that this
problem is thoroughly investigated and addressed properly?

Kyle,
I have confirmed that NCDENR has been in contact with UCPW regarding the odor
complaints. In follow up,
I've learned that UCPW has completed the following items in an effort to address
everyone's concerns:
1. All sewer lines within the complaint areas have been jet cleaned. Typically, on
underloaded systems,
the conditions can turn septic and release sewer gas. Jet cleaning will help to
prevent this problem. As further
development continues, the systems will not be underloaded. 2. All sewer lines
within the immediate vicinity were inspected. One ARV (air release valve) was found
to be frozen
open and emitting a odor. This ARV valve was replaced yesterday.
3. Sodium Hydroxide has been added to the system in an effort to scour the force
main from the lift station.
As you can see, UCPW is diligently working on fixing the problem in order to
eliminate the sewer gases. We
will monitor the situation on our end for follow up. However, we have complete
confidence in UCPW's abilities
to determine the source and eliminate the odor.
Please keep me informed if the odor continues. Your patience is appreciated as
these issues are resolved.

Re: odor in Quellin subdivision - Union Co.
this?
I also walked the area between the WWTP and the creek that runs behind Thayer and
passed by a couple of manholes. I assume those are the manholes that you sealed
while work is done to correct the valve problem. I did not notice any smell from
the two manhole covers I passed which were the two closest to the end of Thayer.
Could you continue your investigation and let us know what you find?
Thank you.

Utilities board under pressure
JULIA OLIVER
Developer Dean Harrell has asked Union's utilities advisory board to think about his sewer
problems.
"I just wanted to take this opportunity to put them in front of you for consideration," he wrote in two
letters describing his residential and commercial projects to board members.
Harrell is the second developer to ask for the board's attention since the county stopped processing
sewer requests at its two biggest plants this year.
The county recently has struggled to address shortages of sewer capacity and drinking water. To
get a handle on the problem, staff and consulting companies are gathering data on past sewer
permitting practices and developing a system to allocate the limited sewer capacity. They are also
looking for a new water source.
Developers need sewer permits before they can install utilities infrastructure and sell lots to builders.
But some board members worry that, as developers' finances are strained by the lack of sewer and
water availability, they will come to the board in greater numbers seeking sympathy for their plights.
"I don't really see that as our current role," said board member Larry Smith. He said he would prefer
that the board deal with broader policy decisions. The board was formed to give advice to
commissioners on utility matters, though some members have expressed frustration that the
mission has never been more clearly defined.
"I don't want a different developer popping up at every meeting, begging and pleading for water and
sewer," he said.
Board vice chairman Donnie Baucom agreed that it is not the board's job to talk to individual
developers. He said that since the board was formed, he's had calls from between five and 10
developers or their representatives, some just asking questions about what's going on.
"Usually I cut it off," Baucom said, "because there's no need for us to get in the middle of this."
Board chairman Rick German could not be reached. But Baucom said he didn't think Harrell's
request would be on the board's agenda Tuesday.
Between April and July, the nine -member board heard three times from representatives of The
Woods, a planned Weddington development that wants to divert sewage to Mecklenburg County to
avoid Union's sewer capacity problems. German said "higher-ups" requested the third presentation,
in which N.C. Board of Transportation member Larry Helms urged the board to consider accepting
The Woods' donation of a road right-of-way.
The board voted to delay discussing that request until an audit of the county's public works
department is done this fall.
Harrell did not return a number of phone calls about his requests.
In a July e-mail to the board, he describes sewer problems at five of his residential and commercial
projects. The letter emphasizes the tax value of the projects and their benefits to the community
Last week, Harrell sent that letter again, with proposed solutions. Some board members said he
also sent the letter by post to their homes.
"The R.D. Harrell Company would like to take a moment to explain our current situation to Union
County in relationship to the status of water/sewer and the on -going concern with our projects," the
letter says. It requests the following:
• Sewer access to 150 homes a year in Harrell's Bonterra Village development off Secrest Shortcut
Road. Harrell says he is finished with about one-third of the 1,395-home development, but will run
out of sewer permits late this fall.
• One-third each year of the sewer capacity needed for a mixed residential and commercial project
in downtown Indian Trail. He says the project has no sewer permits.
• Sewer access for 40 homes per year in the 110-lot housing development Quintessa II, off Potter
Road. He says the project has no sewer permits.
• Permission to use a combination of septic and alternative sewer treatment at Quintessa West, a
120-lot residential development off Potter and Beulah Church roads. Harrell says he wants to use
that system temporarily, until county sewer lines can be installed.
• Sewer access for 50 homes per year at a planned 140-home retirement community on Fincher
Road. He says the project has no sewer access.

Waxhaw elections hinge on growth
MIKE TORRALBA
Waxhaw's municipal elections will turn, as they have in previous elections, on managing growth.
The latest Census estimates put the southwestern Union County town's population at 3,400, an
increase of 30 percent, or about 800 more residents, since 2000. There are few signs that growth
could slow.
For example, the Board of Commissioners last month accepted a voluntary -annexation request for
76 acres of what will become part of the massive Millbridge subdivision. In recent months, Town
Hall added staff to its planning department and funded a new building inspections department.
Voters will choose among two candidates for mayor and five candidates for two open
commissioners seats. Commissioner David Barnes did not file for re-election, having served for
more than 20 years. Former commissioner Tammy Norwood resigned in April, citing frustration with
the board's handling of growth.
Here is a round -up of the candidates:
Mayor
Gary Underwood, 59, the only incumbent seeking re-election, is seeking his second
term.Underwood, fleet manager with Wachovia Corp., served two terms an the Board of
Commissioners in the 1990s. Like all the other candidates, Underwood says growth is the biggest
issue facing the town.
In some ways, he said, the issue is out of the town's hands. The county for now has halted sewer
permits, and funding for improving some major roads is controlled by the N.C. Department of
Transportation — including N.C. 16 and N.C. 75, the town's main arteries. But he said working with
other municipalities and regional organizations will be key to sound growth.
"I think we've handled the growth well, with good growth and some good developers," he said.
Underwood faces Daune Gardner, owner of Creative Plus, a local graphic -design business. She is
running for her first elected office.
Gardner, 35, has experience on volunteer committees to revise Waxhaw's land -use plan and serves
on a committee to revise the town's unified development ordinance (UDO), the 200-page rulebook
for nearly any structure built in the town. She also has served as president of the Waxhaw Business
Association. Last fall, she applied for interim town manager after Martin Irvine abruptly resigned.
Gardner has lived in the Waxhaw area for 14 years, except for three years in the early 2000s as she
worked toward a master's degree in environmental management at Duke University.
She said she is most concerned about "the accelerating rate of growth pressure" on the town in
recent years. She said the town needs a comprehensive plan, "something that looks at all the
elements of planning and growth."
Board of Commissioners
The race for the two open commissioners seats includes two candidates with previous campaign
experience and three political novices.
John Hunt, a 35-year-old paramedic for Mecklenburg County, moved to Waxhaw from Matthews a
year ago.
Hunt says he would make sure major issues are thoroughly researched before the board sets
policy. For example, if liquor -by -the -drink were proposed, Hunt says the board should have a
complete grasp of the proposal's history and its likely impact on the town.
Brian Haug, a planning manager with Family Dollar in Matthews, has lived in Waxhaw for eight
years. He serves on the town's UDO committee.
Haug, 37, said the revised UDO will be key to ensuring that future growth is the right kind of growth
for Waxhaw. He said the town needs to work more actively with local civic and business groups, as
well as with other local governments and regional organizations such as the Mecklenburg -Union
Metropolitan Planning Organization.
"The problem is everything is interconnected," Haug said. "As you look around at the way the town
dealt with (growth) in the past, we dealt with it as if it were in a vacuum."
Chris Michaelson, a 50-year-old reference assistant at the public library in Monroe, has lived in
Waxhaw for nearly 20 years.
Though the county's tight sewer capacity has restricted new development, Michaelson said the town
should consider formally issuing a moratorium on new subdivisions until a revised UDO is in place.
"I don't propose any specific limits on residential growth, but I think we can take a lock at how
adequately we can supply services," he said.
Martin Lane, owner of The Shirt Shop Waxhaw, served one term on the Board of Commissioners
before losing re-election in 2005.
Lane, 34, said his biggest advantages are his previous experience on the board and his knowledge
of the unified development ordinance.
"The inexperience of some board members now is reflected in some actions taken now," Lane said.
"Developers seem to be kind of walking all over and having their way with the town."
Also in the field of candidates is Jane Fialka, 40, who ran for commissioner in 2005 but fell two
votes shy of a seat on the board, just behind Max Walker. A stay-at-home mom, Fialka ran a day
spa in Raleigh before moving to Waxhaw three years ago.

Fialka was ill and could not be interviewed, said her husband, Joe.
He said she would "open a dialogue" with the county commissioners and state road officials to
tackle the town's water, sewer and street problems.

Too many wells can drain the aquifer
After reading your view concerning the possibility of expanding the use of private wells to supply
water for personal consumption and other use, I feel it extremely important to respond.
Well water is obtained from the aquifer, which is a water- bearing underground formation of
unknown capacity. Think of it as an invisible punch bowl of unknown size containing an unknown
amount of punch. Each person desiring some punch puts a straw (well) into the bowl and draws out
what they want. There comes a point when one new straw withdrawing punch leaves the bowl
empty, resulting in no punch for anyone. In my opinion this is not a viable method for government to
rely on to manage growth. Water should be provided by a regulated, public utility for all the citizens.
As for the Weddington Optimist Park, Wesley Chapel Weddington Athletic Association's use of well
water, I recommend you speak to adjoining property owners who "lost" their well due to the
WCWAA drawdown of the water table while maintaining the "lush, green, well -kept fields" you note
in your column.

Water use rises with heat
JULIA OLIVER
The heat could be driving up Union County lawn watering again.
Union's water use in the first six days of August was higher than in that same time last year. The
trend is a small break in what has generally been a trend toward lower water use since the county
began mandatory water restrictions this summer.
County Public Works Director Christie Putnam has attributed the lower water demand to rain and
customers' compliance with the restrictions, which started June 1. Last month, the county used
about 61.7 million gallons less than it had in July 2006.
But from Aug. 1 to Aug. 6, the county used about 4 million gallons more than it did in the same
period last year. Putnam could not be reached Wednesday.
Mike Bailes, director of the water plant Union shares with Lancaster, S.C., said in an e-mail that he
wouldn't be surprised if more local governments began imposing mandatory water restrictions.
"Looking at lake levels on the Catawba, it is starting to get pretty bad," he wrote. "Not only is it bad
hot, it is also bad dry!!!"
Union, the first government in the region to impose such restrictions, has limited customers' lawn
watering to two specific days a week, based on street address.

1.0 INTRODUCTION
House Bill 1160, the Clean Water Act of 1999, was ratified by the North Carolina
General Assembly on July 20, 1999 and signed into law by the Governor on July 21,
1999. This legislation placed significant reporting requirements on entities that own
or operate wastewater systems. This Performance Summary is intended to
establish compliance with said rule.
The Union County Public Works Department is charged with the management,
operation and maintenance of the County's sanitary sewer system. During the
2002-2003 fiscal year the wastewater system was comprised of 6 wastewater
treatment plants (WWTP), over 60 wastewater pumping stations and over 375 miles
of pipe with over 14,000 connections. In addition to the 6 WVVTP's which have a
combined rated treatment capacity of 4.9 million gallons per day (MGD), the
County, through contractual agreement, has 1.95 MGD and 1.0 MGD of purchased
capacity at the City of Monroe WWTP and Charlotte's McAlpine Creek WWTP
respectively.
Public Works' Mission Statement is as follows:
Develop water, sewer and solid waste infrastructure that supports residential,
commercial, industrial and agricultural needs while meeting FederaUState
regulations and providing our customer base with acceptable levels of service at
cost effective rates
2.0 DEFINITIONS
For the purposes of this Performance Report the following definitions apply:
• Aerobic — A condition in which atmospheric or dissolved molecular oxygen is
present in the aquatic environment.
• Automatic Telephone Dialer or ATD — A device connected to the telephone
system that will alert programmed telephone numbers of equipment status.
• Biological Nutrient removal — The process of removing nitrogen and
phosphorus from wastewater using biological processes as opposed to chemical
means.
• Biosolids — A primarily organic solid product, produced by wastewater
treatment processes that can be beneficially recycled. The word biosolids is
replacing the word sludge.
• BOD — Biochemical Oxygen Demand — The rate at which organisms use the
oxygen in water or wastewater while stabilizing decomposable organic matter
under aerobic conditions. The BOD Test is a procedure that measures the rate
of oxygen use under controlled conditions of time and temperature. BOD is
typically used to express the "strength" of wastewater.
Union County Wastewater System
Page 1 Performance Summary FY 02-03

August 2003
• CL2— Chlorine Residual — The amount of chlorine present in the final effluent
after disinfection. Typically measured in micrograms per liter or milligrams per
liter.
— Dissolved Oxygen — Molecular (atmospheric) oxygen dissolved in a
liquid.
• Effluent — Treated wastewater flowing from the treatment system.
• Extended Aeration — A type of wastewater treatment facility in which the
wastewater is retained and treated for a minimum of 24 hours at design flow
before discharge occurs.
• Impeller- A rotating set of vanes in a pump designed to pump or lift water.
• Inflow and Infiltration (I&I) - extraneous water that enters the sanitary sewer
system through openings and/or defects in the collection system.
• Fecal Coliform — The conform (bacteria) found in the feces of warm blooded
animals. The presence of coliform-group bacteria is an indication of possible
pathogenic bacterial contamination.
• MGD — Million Gallons per Day — Volumetric measurement of flow converted to
millions. Example _150 MGD x 1,000,000 =150,000 gallons per day (gpd).
• NH3— Nitrogen as Ammonia — A compound found naturally in wastewater.
The compound is produced by the deamination of organic nitrogen containing
compounds.
• NPDES Permit — National Pollutant Discharge Elimination System -
Permits, required by the Federal Water Pollution Control Act Amendments of
1972, which regulate discharges to surface waters.
• pH — The expression of the intensity of the basic or acidic condition of a liquid.
• Pump Station —A holding tank with pumps that forces wastewater uphill when
flow by gravity is not possible.
• SBR — Sequencing Batch Reactor — A type of wastewater treatment facility
that treats and discharges water in batches as opposed to continuous flow.
• Telemetry — A system by which information pertaining to remote equipment
status is transmitted via radio waves to a central location.
• TSS — Total Suspended Solids — Particles suspended in a liquid.
• Turbidity — The measurement of the clearness or cloudiness of a liquid.

4.0 BIOSOLIDS MANAGEMENT
Biosolids are managed and disposed of in accordance with Permit No. WQ
0007486 issued by the North Carolina Department of Environment and Natural
Resources. Biosolids are stored at both the Crooked Creek and Twelve Mile Creek
WWTP's. The solids are aerobically digested and then applied as "fertilizer" to
permitted sites. The solids are considered stabilized, and thus suitable for land
application, when the volatile solids content is reduced by 38%. If this 38% volatile
solids reduction can not be achieved, then alkaline stabilization, injection or
incorporation is employed to ensure Permit compliance.
5.0 SYNOPSIS OF WASTEWATER COLLECTION SYSTEM
(Fiscal Year 2001-2002)
Currently the Department of Public Works operates and maintains over 60
wastewater pumping stations and nearly 375 miles of pipe with approximately
14,000 connections. The pumping stations are equipped with both audible and
visual alarms. In addition to audible and visual alarms, many stations are equipped
with ATD's or telemetry. All stations without ATD's or telemetry are checked daily,
including weekends and holidays. Pump stations with ATD's or telemetry are check
once per week at a minimum. Emergency back-up power is available via a
combination of permanent and portable generators. Wastewater collection staff
rotate "call duty" for after hour situations that may occur.
Public Works maintains emergency response equipment in a ready state at all
times. This emergency equipment varies in nature from spare electrical parts and
plumbing supplies to vacuum trucks and backhoes. Worker safety is of utmost
importance. Safety equipment such as night lighting, gas monitors, and reflective
cones/signs are also maintained in a ready state.
Public Works has ongoing programs to identify and correct problems associated
with the inflow and infiltration (I&I) of storm water into the sanitary sewer system
and to inspect and clean sewer lines. During the fiscal year 2002-2003 over 88,520
feet of pipe were smoke tested to identify potential sources of I&I. An additional
17,474 feet of main lines have been viewed via CCTV to isolate the source(s) of I&I.
Over 1,000 manholes were inspected for inflow and infiltration sources (and
repaired as appropriate) and approximately 57 miles of pipe were cleaned
throughout the system.
Major system improvements during the fiscal year 2002-2003 include:
> A flow -monitoring study to quantify and better isolate inflow and infiltration in the
system serving the eastern portion of the county.
➢ The complete rehabilitation of 54 manholes in the Crooked Creek Wastewater
Treatment Plant service area.

> Over 900 feet of pipe rehabilitation on the system serving the eastern part of the
county.
> Public Works spent over $45,000.00 in pump upgrades to Ray's Fork Pump
Station.
During the Fiscal Year 2002-2003, the +County's wastewater system collected and
conveyed for treatment in excess of 1.56 billion gallons. Fifty-one spills with a
combined estimated volume of 2.57 million gallons occurred within the system. A

1.0 INTRODUCTION
House Bill 1160, the Clean Water Act of 1999, was ratified by the North Carolina
General Assembly on July 20, 1999 and signed into law by the Governor on July 21,
1999. This legislation placed significant reporting requirements on entities that own
or operate wastewater systems. This Performance Summary is intended to
establish compliance with said rule.
The Union County Public Works Department is charged with the management,
operation and maintenance of the County's sanitary sewer system. During the
2003-2004 fiscal year the wastewater system was comprised of 6 wastewater
treatment plants (WWTP), over 60 wastewater pumping stations and over 400 miles
of pipe with over 16,000 connections. In addition to the 6 WWTP's which have a
combined rated treatment capacity of 4.9 million gallons per day (MGD), the
County, through contractual agreement, has 1.95 MGD and 1.0 MGD of purchased
capacity at the City of Monroe WWTP and Charlotte's McAlpine Creek WWTP
respectively.
Public Works' Mission Statement is as follows:
Develop water, sewer and solid waste infrastructure that supports residential,
commercial, industrial and agricultural needs while meeting Federal/State
regulations and providing our customer base with acceptable levels of service at
cost effective rates

4.0 BIOSOLIDS MANAGEMENT
Biosolids are managed and disposed of in accordance with Permit No_ WO
0007486 issued by the North Carolina Department of Environment and Natural
Resources. Biosolids are stored at both the Crooked Creek and Twelve Mile Creek
WWTP's. The solids are aerobically digested and then applied as "fertilizer" to
permitted sites. The solids are considered stabilized, and thus suitable for land
application, when the volatile solids content is reduced by 38%. If this 38% volatile
solids reduction can not be achieved, then alkaline stabilization, injection or
incorporation is employed to ensure Permit compliance.
5.0 SYNOPSIS OF WASTEWATER COLLECTION SYSTEM
(Fiscal Year 2003-2004)
Currently the Department of Public Works operates and maintains over 60
wastewater pumping stations and over 400 miles of pipe with approximately 16,000
connections. The pumping stations are equipped with both audible and visual
alarms. In addition to audible and visual alarms, many stations are equipped with
ATD's or telemetry. All stations without ATD's or telemetry are checked daily,
including weekends and holidays. Pump stations with ATD's or telemetry are check
once per week at a minimum. Emergency back-up power is available via a
combination of permanent and portable generators. Wastewater collection staff
rotate "call duty" for after hour situations that may occur.
Public Works maintains emergency response equipment in a ready state at all
times. This emergency equipment varies in nature from spare electrical parts and
plumbing supplies to vacuum trucks and backhoes. Worker safety is of utmost
importance. Safety equipment such as night lighting, gas monitors, and reflective
cones/signs are also maintained in a ready state.
Public Works has ongoing programs to identify and correct problems associated
with the inflow and infiltration (I&I) of storm water into the sanitary sewer system
and to inspect and clean sewer lines. During the fiscal year 2003-2004 over
105,000 feet of pipe were smoke tested to identify potential sources of I&I and
48,000 feet of main lines were viewed via CCTV to isolate source(s) of l&I. Over
500 manholes were inspected, and repaired when appropriate. Approximately 33
miles of pipe were cleaned throughout the system.
Major system improvements during the fiscal year 2003-2004 include:
➢ Engineering plans were finalized and monies were appropriated by the Union
County Board of Commissioners to rehabilitate approximately 20,000 linear feet
of sewer lines serving the east side of Union County.

> Engineering plans were finalized and monies were appropriated by the Union
County Board of Commissioners to rehabilitate approximately 17,000 linear feet
of sewer lines serving the Town of Waxhaw.
> The development of a comprehensive sewer system map was initiated.
During the Fiscal Year 2003-2004, the County's wastewater system collected and
conveyed for treatment in excess of 1 billion gallons. Forty-two spills, with a
combined estimated volume of 1.18 million gallons, occurred within the system. A
brief description of each spill is presented below:

1.0 INTRODUCTION
House Bill 1160, the Clean Water Act of 1999, was ratified by the North Carolina
General Assembly on July 20, 1999 and signed into law by the Governor on July 21,
1999. This legislation placed significant reporting requirements on entities that own
or operate wastewater systems. This Performance Summary is intended to
establish compliance with said rule.
The Union County Public Works Department is charged with the management,
operation and maintenance of the County's sanitary sewer system. During the
2003-2004 fiscal year the wastewater system was comprised of 6 wastewater
treatment plants (WWTP), over 60 wastewater pumping stations and over 400 miles
of pipe with over 16,000 connections. In addition to the 6 WWTP's which have a
combined rated treatment capacity of 4.9 million gallons per day (MGD), the
County, throug contractual agreeme t, ha 1.95 MGD and 1.0 MGD of purchased
capacity at the ity of Monroe WWTP nd Charlotte's McAlpine Creek WWTP)
respectively. gS/1,G6 1.0 ryt GA
Public Works' Mission Statement is as follows:
Develop water, sewer and solid waste infrastructure that supports residential,
commercial, industrial and agricultural needs while meeting Federal/State
regulations and providing our customer base with acceptable levels of service at
cost effective rates
2.0 DEFINITIONS
For the purposes of this Performance Report the following definitions apply:
• Aerobic — A condition in which atmospheric or dissolved molecular oxygen is
present in the aquatic environment.
• Automatic Telephone Dialer or ATD — A device connected to the telephone
system that will alert programmed telephone numbers of equipment status.
• Biological Nutrient removal — The process of removing nitrogen and
phosphorus from wastewater using biological processes as opposed to chemical
means.
• Biosolids — A primarily organic solid product, produced by wastewater
treatment processes that can be beneficially recycled. The word biosolids is
replacing the word sludge.
• BOD — Biochemical Oxygen Demand — The rate at which organisms use the
oxygen in water or wastewater while stabilizing decomposable organic matter
under aerobic conditions. The BOD Test is a procedure that measures the rate
of oxygen use under controlled conditions of time and temperature. BOD is
typically used to express the "strength" of wastewater.

• CL2 — Chlorine Residual — The amount of chlorine present in the final effluent
after disinfection. Typically measured in micrograms per liter or milligrams per
liter.
• D.O. — Dissolved Oxygen — Molecular (atmospheric) oxygen dissolved in a
liquid.
• Effluent — Treated wastewater flowing from the treatment system.
• Extended Aeration — A type of wastewater treatment facility in which the
wastewater is retained and treated for a minimum of 24 hours at design flow
before discharge occurs.
• Impeller- A rotating set of vanes in a pump designed to pump or lift water.
• Inflow and Infiltration (MI) - extraneous water that enters the sanitary sewer
system through openings and/or defects in the collection system.
• Fecal Coliform — The coliform (bacteria) found in the feces of warm blooded
animals. The presence of coliform-group bacteria is an indication of possible
pathogenic bacterial contamination.
• MGD — Million Gallons per Day — Volumetric measurement of flow converted to
millions. Example .150 MGD x 1,000,000 = 150,000 gallons per day (gpd).
• NH3— Nitrogen as Ammonia — A compound found naturally in wastewater.
The compound is produced by the deamination of organic nitrogen containing
compounds.
• NPDES Permit — National Pollutant Discharge Elimination System -
Permits, required by the Federal Water Pollution Control Act Amendments of
1972, which regulate discharges to surface waters.
• pH — The expression of the intensity of the basic or acidic condition of a liquid.
• Pump Station — A holding tank with pumps that forces wastewater uphill when
flow by gravity is not possible.
• SBR — Sequencing Batch Reactor — A type of wastewater treatment facility
that treats and discharges water in batches as opposed to continuous flow.
• Telemetry —A system by which information pertaining to remote equipment
status is transmitted via radio waves to a central location.
• TSS — Total Suspended Solids — Particles suspended in a liquid.
• Turbidity — The measurement of the clearness or cloudiness of a liquid.

4.0 BIOSOLIDS MANAGEMENT
Biosolids are managed and disposed of in accordance with Permit No. WQ
0007486 issued by the North Carolina Department of Environment and Natural
Resources. Biosolids are stored at both the Crooked Creek and Twelve Mile Creek
WWTP's. The solids are aerobically digested and then applied as "fertilizer" to
permitted sites. The solids are considered stabilized, and thus suitable for land
application, when the volatile solids content is reduced by 38%. If this 38% volatile
solids reduction can not be achieved, then alkaline stabilization, injection or
incorporation is employed to ensure Permit compliance.
5.0 SYNOPSIS OF WASTEWATER COLLECTION SYSTEM
(Fiscal Year 2003-2004)
Currently the Department of Public Works operates and maintains over 60
wastewater pumping stations and over 400 miles of pipe with approximately 16,000
connections. The pumping stations are equipped with both audible and visual
alarms. In addition to audible and visual alarms, many stations are equipped with
ATD's or telemetry. All stations without ATD's or telemetry are checked daily,
including weekends and holidays. Pump stations with ATD's or telemetry are check
once per week at a minimum. Emergency back-up power is available via a
combination of permanent and portable generators. Wastewater collection staff
rotate "call duty" for after hour situations that may occur.
Public Works maintains emergency response equipment in a ready state at all
times. This emergency equipment varies in nature from spare electrical parts and
plumbing supplies to vacuum trucks and backhoes. Worker safety is of utmost
importance. Safety equipment such as night lighting, gas monitors, and reflective
cones/signs are also maintained in a ready state.
Public Works has ongoing programs to identify and correct problems associated
with the inflow and infiltration (I&I) of storm water into the sanitary sewer system
and to inspect and clean sewer lines. During the fiscal year 2003-2004 over
105,000 feet of pipe were smoke tested to identify potential sources of I&I and
48,000 feet of main lines were viewed via CCTV to isolate source(s) of I&I. Over
500 manholes were inspected, and repaired when appropriate. Approximately 33
miles of pipe were cleaned throughout the system. 4iyj ry4las

water.
• Inflow and Infiltration (I&I) - extraneous water that enters the sanitary
sewer system through openings and/or defects in the collection
system.
• Fecal Coliform — The coliform (bacteria) found in the feces of warm
blooded animals. The presence of coliform-group bacteria is an
indication of possible pathogenic bacterial contamination.
• MGD — Million Gallons per Day — Volumetric measurement of flow
converted to millions. Example 150,000 gallons per day (gpd) /
1,000,000 = 0.150 MGD.
• NH3— Nitrogen as Ammonia — A compound found naturally in
wastewater. The compound is produced by the deamination of organic
nitrogen containing compounds.
• NPDES Permit — National Pollutant Discharge Elimination System
- Permits, required by the Federal Water Pollution Control Act
Amendments of 1972, which regulate discharges to surface waters.
• pH — The expression of the intensity of the basic or acidic condition of
a liquid.
• Pump Station — A holding tank with pumps that forces wastewater
uphill when flow by gravity is not possible.
• Reclaimed Water— Highly treated wastewater that has undergone
advanced treatment processes to remove solids, organics, and
pathogens meeting the State's Health and Safety Standards for
Beneficial Reuse.
• SBR — Sequencing Batch Reactor — A type of wastewater treatment
facility that treats and discharges water in batches as opposed to
continuous flow.
• Telemetry — A system by which information pertaining to remote
equipment status is transmitted via radio waves to a central location.
• TSS — Total Suspended Solids — Particles suspended in a liquid.
• Turbidity — The measurement of the clearness or cloudiness of a
liquid.

3.0 SYNOPSIS OF WASTEWATER TREATMENT FACILITIES
(Fiscal Year 2008-2009)
During the 2008-2009 fiscal year the Department of Public Works
operated and maintained a total of five (5) active wastewater treatment
facilities and maintained one (1) inactive facility. Although each Permit
requires facility visitation daily, excluding weekends and holidays, Public
Works' wastewater treatment facilities are checked 7 days per week, 365
days per year. All treatment facilities are equipped with emergency back-
up power generators. Each treatment facility is equipped with an
automated telephone dialer (ATD). In addition to an ATD, each facility has
both audible and visual trouble alarms. Wastewater treatment plant staff
rotate "call duty" for after hour situations that may arise.
A brief overview of each facility and a performance summary table for
each facility is provided herein.
3.1 Twelve Mile Creek Water Reclamation Facility
Permit No. NC0085359. Twelve Mile is an extended aeration facility
utilizing biological nutrient removal and tertiary filtration. Disinfection is
accomplished via UV (ultraviolet light). Twelve Mile effluent is discharged
into Twelve Mile Creek, which is part of the Catawba River Basin. The
facility is permitted to discharge up to 6.0 MGD of treated wastewater.
January 18, 2008, the Twelve Mile facility was permitted to dispense bulk
"reclaimed" water to authorized users (Permit No. WQ0032519). Bulk
reclaimed water has multiple "Non -potable" uses which can serve to
reduce demand upon the potable water supply and distribution system.
The bulk reclaimed water program was suspended in the fall of 2008
pending a system upgrade which includes secondary disinfection.
Operational changes have been successfully implemented to control
phosphorous quantities discharged. A "Plant Reliability Enhancements"
project which commenced February 4, 2009 will serve to aid monitoring
and control operations upon completion in early 2010. An "Odor Control"
project also commenced on February 4, 2009 and will serve to scrub the
foul air which may be emitted on occasion from specific process units.
This project is slated for completion later in 2010. Twelve Mile Creek
WWTP is located at 8299 Kensington Drive and serves Waxhaw as well
as portions of Indian Trail, Stallings and Weddington. Please refer to Table
3-1
3.2 Crooked Creek Water Reclamation Facility
Permit No. NC0069841. Crooked Creek is an extended aeration facility
utilizing tertiary filtration. Disinfection is accomplished via UV (ultraviolet
Tight). Crooked Creek effluent is pumped over 17,000 feet to discharge
into the North Fork Crooked Creek which lies in the Yadkin Pee Dee River

Basin. This facility is permitted to discharge up to 1.9 MGD of treated
wastewater. January 18, 2008, the Crooked Creek facility was permitted
to dispense bulk "reclaimed" water to authorized users (Permit No.
WQ0032520). Bulk reclaimed water has multiple "Non -potable" uses
which can serve to reduce demand upon the potable water supply and
distribution system. As with Twelve Mile Creek, the bulk reclaimed water
program was suspended in the fall of 2008 pending a system upgrade
which includes secondary disinfection. Crooked Creek is located at 4015
Sardis Church Road and serves the Indian Trail, Lake Park and Stallings
areas. Please refer to Table 3-2.
3.3 Hunley Creek Wastewater Treatment Plant
Permit No. NC0072508. Hunley Creek is a Sequencing Batch Reactor.

effluent is discharged into Goose Creek, which lies in the Yadkin Pee Dee
River Basin. This facility is permitted to discharge up to .231 MGD of
treated wastewater. Discharge permit limits changed February 2005. The
new limits are more stringent than the design capabilities of the Hunley
Creek facility. The facility was taken off-line May 10, 2006 via flow
diversion project and remains inactive. Hunley Creek is located at 6913
Stevens Mill Road and serves the subdivisions of Shanamara, Hunley

4.0 BIOSOL IDS MANAGEMENT
Biosolids are managed and disposed of in accordance with Permit No.
WQ0007486 issued by the North Carolina Department of Environment and
Natural Resources. Biosolids are stored at both the Crooked Creek and
Twelve Mile Creek WWTPs. The solids are aerobically digested and then
applied as "fertilizer" to permitted sites. The solids are considered stabilized,
and thus suitable for land application, when the volatile solids content is
reduced by 38%. If this 38% volatile solids reduction can not be achieved,
then alkaline stabilization, injection or incorporation is employed to ensure
Permit compliance.
5.0 SYNOPSIS OF WASTEWATER COLLECTION SYSTEM (Fiscal Year 2008-2009) 6S2 eNu t z°S
UCPW currently operates and maintains approximately 65 wastewater pump lb%
stations and over 580 linear miles of sewer lines inclmain udin ce , which P��
�_g_for s
serve approximately 27,430 customers throughout the county. All puThp 04()
stations are equipped with both audible and visual alarms as well as either „ Q„
automated telephone dialer (ATD) or telemetry which alert staff when alarm ll�
conditions occur. Inspections of all stations meet or exceed State
requirements. Approximately 80% of all pump stations are checked a
minimum of twice weekly and 20% are checked once a week to ensure proper
maintenance and operation. Emergency back up power is provided to all
stations via portable or permanent generators. Wastewater personnel are on a
call rotation providing staff coverage 24 hours per day, 7 days per week, 365
days a year.
Public Works maintains emergency response equipment in a ready state at all
times. This emergency equipment varies in nature from spare electrical parts
and plumbing supplies to vacuum trucks and backhoes. Workers' safety is of
utmost importance. Safety equipment such as night lighting, gas monitors,
trenching and shoring equipment, and reflective cones/signs are always
readily available.
Public Works has ongoing programs to identify and correct deficiencies
associated with the wastewater collection system. The programs are listed
below with results of this year's efforts to maintain the collection system.

High priority lines such as aerial creek crossings, lines subject to erosion
and/or problematic areas -are visually inspected at a minimum of semi-
annually. High priority lines are inspected more frequently after periods of
heavy rain and flooding.
Another important program is the FOG (Fats, Oils, and Grease) program. This
program is aimed at reducing back-ups and overflows by educating the public -
of the hazards associated with the disposal of grease and grease related by-
products into the wastewater system. A grease trap- inspection program hail/
provided better data ensuring that restaurants and other food preparation
facilities properly maintain grease traps and interceptors.
Major system improvements during fiscal year 2008-2009 include:
✓ The continued development of a comprehensive electronic sewer
map. This map will help -Public Works in tracking problematic areas
as well as track scheduled maintenance, improvements, and repairs
throughout the service area. {V�sb.((�
✓ CCTV/Cleaning-efforts concentrated-witt nJJCPW's satellite® it
s sv tems_were conducted -to identify areas of inflow and infiltration. -e.\y JJ�
✓ Reclaimed bulk water program was introduced to reduce the effects
of drought conditions.
During the Fiscal Year 2008-2009, the County's wastewater system collected
nearly 2.5 billion gallons. There were twenty-one (21 sanitary sewer
overflows with a combined volume of approximately 18;355 gallons that
occurred within the collection system during the reporting period. The
overflows are summarized below. / pod c /S,a)

TO: Food Preparation Establishments
FROM: Union County Public Works
SUBJECT: Grease interceptors and Traps
Union County Sewer Use Ordinance
Union County Public Works (UCPW) would like to inform you that grease accumulation in sanitary sewer
lines is a leading cause of sewer back ups. Sewer back ups can adversely affect the environment,
endanger human health, result in property damage and are subject to enforcement actions from the North
Carolina Department of Environment and Natural Resources,- Division of Water Quality. Please be aware
that failure to properly maintain your grease interceptor is a direct violation of the Union County Sewer
Use Ordinance (UCSUO) and is punishable by civil penalties and/or termination of services.
Failure to properly maintain a grease interceptor directly violates Sections 2.1(a), b (4) and b (13) of the
UCSUO. Section 2.7 (a) of the UCSUO requires that "Users shall provide treatment as necessary to
comply with this ordinance...." and "Any facilities necessary for compliance shall be provided, operated
and maintained at the users expense. Additionally, Section 2.7 (b) 3 requires that interceptors be
inspected, cleaned and repaired regularly, as needed, by the user at their expense.
UCPW recommends the following:
✓ Recycle waste cooking oil. The oil should be stored in a leak proof container with a lid or
cover. The container should be stored in a location that will prevent any spillage from
entering the County sewer system, storm drains or ditches. The contents of the container
should be disposed of in accordance with best management practices.
✓ Clean under sink grease traps weekly. The grease should be stored in a leak proof container
with a lid or cover. The container should be stored in a location that will prevent any spillage
from entering the County sewer system, storm drains or ditches. The contents of the
container should be disposed of in accordance with best management practices.
✓ Interceptors should be cleaned (pumped) monthly. Please be aware that UCPW does not
allow water to be reintroduced into grease interceptors or the sanitary sewer as part of
interceptor maintenance practices. After cleaning, the interceptor should be filled to at least
half capacity with potable water. At no time should interceptors have more than 25% of the
working capacity occupied by grease and/or grit
✓ When practical, use water temperatures less than 140 ° F for dish washing. Use a three -sink
dishwashing system consisting of a wash basin, rinse basin and sanitizing basin.
✓ When practical, post "No Grease" signs above sinks, dishwashers and floor drains.
1 When practical °dry wipe" pots, pans and dishware prior to dishwashing.
If additional information is required, please do not hesitate to contact Mark Tye at [phone].

Practices for Fats,
Grease
Residual fats, oils, and grease (FOG) are by-products that food service
establishments must constantly manage. Typically, FOG enter a facility's
'plumbing system from ware washing, floor cleaning, and equipment
sanitation. Sanitary, sewer systems. are neither designed nor equipped to
handle the FOG that accumulates. on the interior.of the municipal sewer
collection system pipes: Over, 30% of North Carolina's 1999 sanitary
sewer overflows were the result of pipe blockages from FOG accumulation
from residential, institutional and, commercial sources. The best. way to
:manage FOG is to keep the material out of the plumbing systems. The
;!:following are suggestions for•proper_:FOG management:
Dry Clean -Up
Practice dry cleanup. Remove food waste with "dry" methods such
r..
as scraping, wiping, or sweeping before using "wet" methods that
use water.. Wet methods,typically wash .the'water and waste
materials into the drains where it eventually collects on the interior
walls of the drainage pipes. Do not pour grease, fats or oils from
cooking down the 'drain, and do not use the sinks to dispose of
food scraps. Likewise it, is' important to educate kitchen staff not
to remove drain screens as this may allow paper of plastic cups,
straws, and other utensils to enter the plumbing system during
clean up. Thesuccess of dry clean up is dependent upon the
behavior of the employee and availability of the tools for removal
'of food waste before washing. To practice dry clean up:
■ Use rubber scrapers to remove fats, oils and grease from
cookware, utensils, chafing dishes, and serving ware.
„ri■ Use food;grade paper to soak up oil and, grease under fryer
baskets....
• .Use paper towels to wipe down work areas. Cloth towels will
accumulate grease that will eventually ..end .up in your drains
from towel washing/rinsing. ,-

Spill Prevention
Grease' Goblin
Preventing spills reduces the amounts of waste on food preparation
and serving areas that will require clean up. A dry workplace is
safer for employees in avoiding slip, trips, and falls. For spill
prevention:
• Empty containers before they are full to avoid spills.
• Use a cover to transport interceptor contents to rendering
barrel.
• Provide employees with the proper tools (ladles, ample
containers, etc.) to transport materials without spilling.
Maintenance
Maintenance is key to avoiding FOG blockages. For whatever
method or technology is used to collect, filter and store FOG,
ensure that equipment is regularly maintained. All staff should
be aware of and trained to perform correct cleaning procedures,
particularly for under -sink interceptors that are prone to break
down due to improper maintenance.. A daily and weekly
maintenance schedule is highly recommended.
• Contract with a management company to professionally clean
large hood filters. Small hoods can be hand -cleaned with spray
detergents and wiped down with cloths for cleaning. Hood
filters can be effectively cleaned by ;routinely spraying with
hot water with little or no detergents over the mop sink that
should be connected to a grease trap.; After hot water rinse
(separately trapped), filter panels can go into the dishwasher.
'For hoods to operate properly in the removal of grease -laden
vapors, the ventilation system will also need to be balanced
with sufficient make-up air.

NORTH CAROLINA
PRETREATMENT CONSORTIUM

• Skim/filter fryer grease daily and change oil when necessary.
Use a test kit provided by your grocery distributor rather than
simply a "guess" to determine when to change oil. This extends
the life of both the fryer and the oil. Build-up of carbon
deposits on the bottom of the fryer act as an insulator that
forces the fryer to heat longer, thus causing the oil to break
down sooner.
• Collect fryer .oil in an oil rendering tank for disposal or
transport it to a bulk oil rendering tank instead of discharging
it into a grease interceptor or waste drain.
• Cleaning intervals depend upon the type of food
.establishment involved. Some facilities require monthly or
once every two months cleaning. Establishments that operate
a large number of fryers or handle a large amount of fried
foods such as chicken, along with ethnic food establishments
may need at least monthly cleanings. Full -cleaning of grease
traps (removing all liquids and solids and scraping the walls)
is a worthwhile investment. Remember, sugars, starches and
other organics accumulate from the 'bottom up. If sediment
is allowed to accumulate in the trap, it will need to be pumped
more frequently.
! -Develop a rotationsystem. if multiple fryers are in use.
Designate a single fryer for products that are particularly high
in deposits, and change that one more often.
Oil & Grease'Collection/Recycling & Food Donations
:.FOG are, commodities, that if handled properly can be treated as a
valuable resource.
Begin thinking of oil and grease as a valuable commodity.
Some rendering companies will offer services free -of -charge
and others will give a rebate on the materials collected. Note
• `that these companies must be properly permitted by the
'Division of Waste 'Management,' Solid Waste Section at
' 919.733.0692; in order to' remove FOG from a facility. A list
of grease collectors'can be found in the Directory of Markets for
Recyclable Materials at'www.p2pays.org/DMRM or by calling
DPPEA at. 1:800.763.0136.» ~'
• Use 25-gallon'rendering barrels with covers for onsite
collection of oil and grease other than from fryers. Educate
kitchen staff 'On the importance of keeping outside barrels
covered 'at all times. During storms, uncovered or partially
covered barrels allow storm water to enter the barrel resulting
in oil running onto the ground and possibly into storm drains,
and 'can '"contaminate" an otherwise useful by-product.
• Use a 3-compartment sink for ware washing. Begin with a hot
pre -wash, then a scouring sink with detergent, then a rinse sink.
• Make sure all drain screens are installed.
• Prior to washing and rinsing use a hot water ONLY (no
detergent) prerinse that is separately trapped to remove non -
emulsified oils and greases from ware washing. Wash and rinse
steps should also be trapped.
• Empty grill top scrap baskets or scrap boxes and hoods into
the rendering barrel.
• Easy does it! Instruct staff to be conservative about their use
of fats, oils and grease in food preparation and serving.
• Ensure that edible food is not' flushed down your drains.
Edible food waste may be donated to a local food bank.
Inedible food waste can be collected by a local garbage feeder
who will use food discards for feeding livestock. Food
donation is a win -win situation. It helps restaurants reduce
disposal costs and it puts the food in the hands of those who
can use it. Check the Directory of Marken for Recyclable Materials
for a list of food waste collectors.
Grease Traps
• For grease traps to be effective, the units must be properly
sized, constructed, and installed in a location to provide an
adequate retention time for settling and accumulation of the
FOG. If the units are too close to the FOG discharge and do
not have enough volume to allow amassing of the FOG, the
emulsified oils will pass through the unit without being
captured. For information on properly locating, constructing,
and sizing grease traps, contact your local county and city
representatives and examine EPA guidance documents.
• Ensure all grease -bearing drains discharge to the grease trap.
These include mop sinks, woks, wash sinks, prep sinks, utility
sinks, pulpers,. dishwashers, prerinse sinks, can washes, and
floor drains in food preparation areas such as those near a
fryer or tilt/steam kettle. No toilet wastes should be plumbed
to the grease trap.
• If these suggested best management practices do not
adequately reduce FOG levels, the operator may consider
installing a second grease trap with flow -through venting. This
system should help reduce grease effluent substantially.
Consumer Tip
Buyer beware! When choosing a method of managing your oil
and grease, ensure that it does what the vendor says it will do.
Some technologies or "miracle cures" don't eliminate the problem
but result in grease accumulations further down the sewer line.
"Out of sight" is not "out of mind." Check the vendor's references.

FACT SHEET FOR
estaurant Oil an
Grease Rendering
Introduction
Improperly' managed oil and grease from restaurants has
become a significant problem for wastewater collection and
treatment systems. Fats, oils, and greases (FOG) coat, con-
geal, and accumulate in pipes, pumps, and equipment, lead-
ing to the costly and hazardous flow of waste grease into
drain lines, sewer lines, lift stations, drain fields, and Pub-
licly Owned Treatment Works (POTWs). Improper disposal
can result in high biological oxygen demand (BOD) and
chemical oxygen demand (COD) levels, increased operat-
ing costs, and clogged: collection 'systems.' Approximately
30% of the 3,800 reported sewer system overflows in North
Carolina in 1998,were .caused by,F,OG blockage of the sew-
ers.
Where Does Grease Go 7
-When It Leaves a Restaurant? •
A grease trap is designed to prevent grease, oil, solids, and
other debris from entering the waste stream, where it be-
comes a problem by dogging sewers and disrupting the water
flow in the system. The grease trap captures those wastes
and contains them until a rendering company can properly
dispose them.
A grease trap should be checked and maintained to ensure
it is working properly. Backups, odors, and drainage prob-
lems are signs that the grease trap is not functioning as it
should.
Grease Recycling
While pretreating wastewater through the use of grease traps,
skimmers, separators, and process flow treatment systems
such as carbon filtration or coagulation units can greatly
reduce the problem, source reduction of oil and grease must
be the first course of action. Through dry cleanup, the de-
velopment of an efficient collection system and rendering
program, wastewater problems can be avoided. Rendering
companies or "grease recyclers" will accept oil, grease, and
other animal byproducts, including deep fry fat and bones,
thereby turning a nuisance waste material into a beneficial
product such as animal feeds.

How is Waste Oil and Grease Recycled?
Waste oil.and grease is tested for pesticides and other con-
taminants.. Material is placed in a settling tank to remove
solids, heated in a vacuum to volatize impurities and is then
sold to companies for .use as animal feed additives, in soap
production, oils, cosmetic and skin care products, and in
composting..:
Benefits of Rendering
■ Compliance — Many communities have sewer use
ordinances that severely limit the allowable concen-
trations of oil and grease in wastewater. New state
policies are being enacted that will require more
communities to develop sewer use ordinances and
wastewater discharge limitations. Penalties may be
incurred when higher concentrations are found.
Rendering prevents grease from reaching the sewer
system and thereby helps restaurants maintain com-
pliance.
Cost Avoidance — The charge for pumping out a
grease- trap is considerably more than the service
fee chargedbya. renderer.: Furthermore, with dry
cleanup and .other source reduction techniques,
many restaurants are reducing their water consump-
tion and .sewer use and are saving money. Render-
ing also helps restaurants .avoid discharge penalty
charges. , . .
Economic Incentives := Renderers' service fees are
low and often provided at no charge. In some cases,
rendering companies are willing to pay for restau-
rant oil and grease.
Environmental Savings — Natural resources and en-•
ergy are conserved through source reduction and
recycling. FOG recycling keeps these materials from
clogging municipal sewer lines, as well as using valu-
able landfill space and diverts it to a useful pur-
pose.

clable Materials at: www.p2pays.org/DMRM/default.htm,

Questions to Ask a Renderer
When looking for an oil and grease renderer, it is impor-
tant to ask the right questions, which may include:
1) Do you provide collection containers?
2) Do you provide transportation?
3) Can I expect revenue for my material? If not, what
is your service fee?
4) 'What are your specifications? What constitutes con-
tamination?
5) If there is a problem, who should I contact?
Remember that fats, oils, and greases are commodities and
should be treated as valuable resources that can and should
be recycled whenever possible.

GETTING STARTED
To reduce water consumption whether in an office or
commercial/industrial setting, consider the three -step
process. below Foremost, employees must understand
how their job affects water use in their work environment.
Solicit ideas from those most involved with the daily
operations and activities of the organization. Make
conserving water part of their job by having them
identify where water is used, whether in bathrooms or
manufacturing operations. Once the areas of water
consumption have been determined, engage the
employees to help implement conservation measures.
O Educate and involveemployees on water
cons ervation,
❑ Locate all;water using sources (bathrooms, wash
sinks, hoses, dish machines, HVAC, cooling water,.
etc.) in facility; and
❑ Identify and implement water conservation options.
IMMEDIATE CONSERVATION
OPTIONS
Repair Leaks!
❑ Ensure water meters are working properly to
accurately measure water use and detect leaks.
, O Inspect all,toilets. A leaking toilet can waste up to
50 gallons of water per day.
❑ Inspect all faucets, spigots and showerheads. A
dripping faucet/showerhead can waste up to 1,000
gallons of water per week.
❑ Check all water pipes for leaks and repair
immediately. A 1 /32" hole in a pipe wastes 6,300
gallons each week.
Kitchen Practices (About half the water used in
restaurants is used in kitchen operations)
❑ Plan ahead. Do not use running water to thaw frozen
foods; place in refrigerator to defrost.
❑ Serve water only upon request and consider smaller
size glasses.
❑ Turn off continuous flow to wash drain trays of
beverage islands; clean thoroughly as needed.
❑ Reduce the flow to dipper wells for ice cream scoops
and other utensils, or rinse scoop and place on dry,
clean surface.
❑ Pre-soak utensils and other wares in sinks rather
than under running water.
❑ Discontinue on -site linen washing; send laundry to
commercial facility outside drought area.
Dry Clean-up
❑ Use brooms, squeegees and wet/dry vacs to clean
surfaces before washing with water; do not use hoses
as brooms.
❑ Reduce the frequency of kitchen floor hosing by
using dry methods; all hoses should have high
pressure/low volume shut-off nozzles.
❑ Sweep and scrape parking lots/sidewalks/window
surfaces rather than washing with water.
❑ Switch from wet/steam carpet cleaning to dry
powder cleaning.

Ice Machine Use
❑ Set automatic optic sensors to minimum fill levels
to provide lowest possible daily requirement
❑ Ensure units are air-cooled and not water-cooled.
Dish Machine Use
❑ Wash only full loads and turn off when not in use.
❑ Replace spray heads with more water- efficient ones.
❑ Ensure water pressures and flows to machine are
set at minimum required setting.
Building Management
❑ Reduce water pressure to building and associated
fixtures (sinks, toilets, showers, laundry and
dishwashing machines).
❑ Turn off any unnecessary flows and equipment when
not in use. '
❑ Adjust boiler and cooling tower blowdown rates to
maintain total dissolved solids at manufacturer's
recommended levels. '
❑ Shut off water-cooled air conditioning units when
not needed; replace old units with air-cooled
models.
Landscaping
❑ • Water only when needed. Look for signs of wilt
before watering, and water only in morning or
evening to avoid evaporation.
❑ Install automatic`rain shut-off devices on sprinkler
systems.. .
❑ Consider using drip irrigation.
. ❑ Avoid runoff! Ensure sprinklers are directed to
landscape areasand not parking lots and sidewalks.
❑ Put in drought tolerant plants andgrasses.
Refer to Landscaping/Irrigation checklist for more
detailed information.
LONG TERM OPTIONS
Purchasing & Menu/Recipe Modifications
❑ Purchase salads, fruits and vegetables in "ready -to -
serve" form to avoid cleaning and preparation wash
associated with fresh produce.
❑ Buy ice from commercial vendors outside drought
restriction areas.
❑ Offer bottled water at cost to customers. Place signs
in strategic locations to inform customers of
change and reasons why tap water is unavailable.
❑ Obtain beverages in ready -to -use form (tea, canned
sodas, etc.) to reduce amounts of water used for
beverage preparation.
❑ Use single -service eating and drinking utensils
Fixture Retrofits/Replacements
❑ Install faucet aerators to increase pressure and reduce
volume of water used.
❑ Install toilet tank water displacement devices (toilet
dams, weighted bottles, etc.).
❑ Retrofit flushometer (tankless) toilets with water -
saving diaphragms (saves 20 percent per flush).
❑ Replace toilets and urinals with low -volume units
(saves up to three gallons per flush).
❑ Consider new machine purchases such as water
efficient dish machines, air-cooled ice machines, and
air-cooled refrigeration units. Many new dishwashing
models for food service equipment use 40 percent
less heated water.
❑ If you have water-cooled air conditioners, consider
switching to more efficient air-cooled units.
Water Reuse (Ensure water is collected for reuse prior to drain
disposal.)
❑ Reuse rinse water from the dishwasher as flush water
in garbage disposal units.
❑ Reuse water from the steam table to wash floors.
❑ Reuse final rinse water from multi -compartment
(pot) sinks as makeup water for primary basin
rinsing/soaking water or to clean floors in nonfood
areas.

On May 1, 2007 a representative from Union County Public Works (UCPW) inspected
the grease receptor serving your restaurant. The inspection was prompted by a grease
blockage in the sewer line serving your restaurant. At the time of the inspection, grease
was observed in the outdoor mop basin which is connected to the sanitary sewer
system. Please be aware that it is a direct violation of the Union County Sewer Use
Ordinance (UCSUO) to introduce grease in excess of 150 mg/I into the sanitary sewer
system. Violations are punishable by civil penalties and/or termination of services. An
explanation of the cause of the violation and corrective measures taken is required.
Failure to properly maintain a grease interceptor directly violates Section 2.1(a), b (4)
and b (13) of the UCSUO. Section 2.7 (a) of the UCSUO requires that "Users shall
provide treatment as necessary to comply with this ordinance...." and "Any facilities
necessary for compliance shall be provided, operated and maintained at the users
expense". Additionally, Section 2.7 (b) 3 requires that interceptors be inspected,
cleaned and repaired regularly, as needed, by the user at their expense.
UCPW recommends the following:
✓ Recycle waste cooking oil. The oil should be stored in a leak proof container
with a lid or cover. The container should be stored in a location that will
prevent any spillage from entering the County sewer system, storm drains or
ditches. The contents of the container should be disposed of in accordance
with best management practices.

✓ Clean under sink grease traps weekly. The oil should be stored in a leak proof
container with a lid or cover. The container should be stored in a location
that will prevent any spillage from entering the County sewer system, storm
drains or ditches. The contents of the container should be disposed of in
accordance with best management practices.
✓ Interceptors should be cleaned (pumped) monthly. Please be aware that
UCPW does not allow water to be reintroduced into grease interceptors or the
sanitary sewer as part of interceptor maintenance practices. After cleaning,
the interceptor should be filled at least half capacity with potable water. At no
time should interceptors have more than 25% of the working capacity
occupied by grease and/or grit
✓ When practical, use water temperatures less than 140 ° F for dish washing,
use a three -sink dishwashing system consisting of a wash basin, rinse basin
and sanitizing basin.
✓ When practical post "No Grease" signs above sinks, dishwashers and floor
drains.
✓ When practical "dry wipe" pots, pans and dishware prior to dishwashing.
In order to avoid escalated enforcement action against your facility for
failure to meet requirements of the UCSUO, you must submit a written
explanation of the cause of the violation and a plan for satisfactory
correction thereof to the following address within 30 days:

Re: Grease Interceptor
To Whom It May Concern:
I am writing this letter to you as a follow up to a letter received from UCPW to the
McDonald's in Indian Trail, NC regarding their grease interceptor.
On Tuesday April, 4m I met with Nelson Bakei(?)He uncovered our grease traps and
explained in detail what the expectations were. I also met with Carolina By Products, the
company that pumps and maintains our tanks and reviewed those expectations.
I had a follow up conversation with the supervisor of Carolina by Products and our traps
have been maintained again. We may also be switching from a 12 week maintenance to
an 8 week maintenance if deemed necessary.
Sincerely,
Becky Walton
Operations Consultant
