STEAM ELECTRIC GENERATING PLANT NPDES WASTEWATER PERMIT RENEWAL
University of North Carolina at Chapel Hill Permit No. NC0025305
The wastewater treatment system is located within, and provides service to,
the Steam Electric Generating Plant (Boiler Plant) Complex located on the
campus of the University of North Carolina at Chapel Hill. The complex is
located on an 11.5-acre site between Cameron Avenue and McCauley Street,
east of the intersection of Robertson Street and Cameron Avenue.
The WWT system consists of two settling tanks, a caustic rapid mix tank, an
acid rapid mix tank, a chemical feed system, a 106,400-gallon equalization
basin (EB) for excessive stormwater flows, and a metering manhole
containing a Parshall flume. The WWT system utilizes an acid feed system
and a caustic feed system to adjust the pH of the wastewater prior to it
being transferred to settling basins where solids are removed. All acid
wastes are routed through an oil/water separator prior to their release to
the caustic rapid mix tank, for pH adjustment. The polymer feed system
provides for the introduction of polymers to the caustic rapid mix tank.
Caustic wastes are transferred directly to the acid rapid mix tank for pH
adjustment prior to transmission to the settling basin.
Boiler Plant wastewater and potentially contaminated stormwater runoff are
delivered to the wastewater treatment (WWT) system via the industrial waste
collection piping for treatment prior to discharge. The WWT system is
presently permitted, by NPDES Permit No. NC0025305 (Appendix A), to
discharge 70,200 gallons per day of treated effluent to an unnamed
tributary of Morgan Creek located in the Cape Fear River Basin; however,
the hydraulic capacity of the WWT system, as designed, is 92,234 gallons
per day according to the Process and Instrumentation Diagram (P&ID), Figure
I. The current NPDES Permit expires July 31, 1993. Additionally, the
University is operating the WWT system under a Special Order by Consent,
EMC WQ No. 89-70, Amendment III (Appendix B) dated November 5, 1992.

The University is presently installing modifications and making adjustments
to the Boiler Plant to reduce the excessive flow and temperature problems
that have plagued the WWT system in the past. These modifications should
also reduce the problems with pH, Iron and Total Suspended Residue.
Currently, flow from these sources amounts to about 102,348 gallons per
day, excluding stormwater runoff, according to the aforementioned effluent
study.
The modifications and adjustments include, but are not limited to,
following:
Installation of a reclaim tank to collect and redirect turbine
gland leakage, a major contributor to excess heat and flow,
from the WWT system;

The modifications listed above are expected to reduce the average daily
flow to less than 40,000 gallons per day. However, this figure does not
include a flow allowance for expected University growth nor does it include
flow from stormwater runoff. Figure I indicates, during peak operating
conditions the flow can be expected to increase from 70,200 gpd to 92,234
gpd or an increase of 22,034 gpd. The stormwater flow, based on the design
of the equalization basin is expected to add 15 gpm (21,600 gpd) to the
flow. Therefore, after the modifications and adjustments have been
implemented the discharge is expected to be distributed as follows:

The WWT system has consistently operated within the Permit limits for all
parameters with the exception of: 1) pH; 2) temperature; 3) flow; and
4) Iron concentration. Total Suspended Residue has occasionally exceeded
the Permit limit as well.
The University is authorized under NPDES Permit No. NC0025305 to discharge
from its WWT System to an unnamed tributary of Morgan Creek which lies in
the Cape Fear River Basin. The Permit was last renewed August 1, 1988, and
will expire July 31, 1993. The treatment works originally consisted of a
200,000-gallon lagoon and oil skimmer. During the last Permit renewal, in
1988, a request was made to construct the present WWT system as part of the
boiler replacement project. The existing permit includes under A.(l)
discharge limitations that recognize the operation of the lagoon system
until completion of the replacement power plant. The lagoon was removed
from service in December, 1992, and all wastewater flow is now routed to
the WWT system.
Plant activities, is collected and treated by the on-site WWT system.
106,400-gallon equalization basin has recently been constructed to buffer
the stormwater flow that, in the past, would enter the wastewater stream
during a storm event and overload the system. The addition of the
equalization basin is expected to greatly increase the efficiency of the
treatment process during a storm event.
The University filed a Notice of Intent on September 28, 1992, to combine
the stormwater discharge and wastewater discharge into NPDES Permit
NC0025305 as noted in the cover letter of Appendix C. A detailed
description of the stormwater collection system and potential sources of
contamination are also contained in Appendix C.

University of North Carolina at Chapel Hill Permit No. NC0025305
In an attempt to bring the operation of the WWT system within the actual
Permit limits, the University has been operating under a Special Order by
Consent (Appendix B) while making adjustments to the Boiler Plant in an
effort to produce an effluent that complies with all parameters of the
discharge Permit. It is expected that the aforementioned modifications and
adjustments will bring the WWT system into compliance with the requested
discharge Permit. The effluent reports from September 1991 through November
1992 are included as Appendix D. Included in Appendix D are effluent
reports for discharge point No. 001 which will no longer be required.
Sampling for the Priority Pollutant List was performed on January 27 and
January 28, 1993 by IEA, Inc. Results will be available in approximately
fifteen days and will be immediately forwarded to NCDEM.
The University presently contracts to remove sludge from each of the two
settling basins on .an alternating, bi-monthly schedule. The amount of
sludge disposed is approximately 50 cubic yards per month or about 600
cubic yards per year. The "Specification for Sludge Disposal From
Wastewater Treatment Facility at UNC-CH Power Plant" is included as
Appendix F. Within these specifications, wastewater generated from the
clean-out process is trucked to Laidlaw Environmental Services in
Chattanooga, Tennessee, to undergo treatment. Solids generated from the
clean-out process are trucked to Smyrna, Tennessee for disposal in a
sanitary landfill. TCLP and Paint Filter Test analyses of the sludge
indicate that concentrations of the tested compounds are below
quantification limits and hence the EPA limits. Sludge laboratory analyses
for all compounds required by law are provided in Appendix G.
An analysis of various alternatives to stream discharge is required in
accordance with 15A North Carolina Administrative Code Subchapter 2H
.0105(c)(2) and Subchapter 2B .0201(c)(1) to ensure that the disposal
method employed is the most environmentally sound and cost effective one

The location of the Boiler Plant Complex, in downtown Chapel Hill, and
the lack of sufficient land area required for a spray irrigation system
precludes the use of land application as a wastewater disposal method.
It is more cost effective for the University to treat its own
industrial wastewater than to discharge it to OWASA;

surface water discharge remains the only viable
environmentally sound alternative available to the University for
disposal of its treated wastewater effluent from the Boiler Plant WWT

various disposal alternatives currently allowed under the regulations, with
respect to the Boiler Plant WWT System, is provided below:
Based on the Figure I, 1,500 gpd of sanitary sewage from the Boiler
Plant is discharged to OWASA. Additionally, an average daily flow of
18,093 gallons of cooling tower blowdown is also discharged to OWASA.
The remaining volume of wastewater from industrial sources is not
discharged to OWASA for the following reasons:

an allowance for peak flow, anticipated University growth, and
stormwater runoff;
The University of North Carolina at Chapel Hill Boiler Plant WWT Treatment
System is permitted under NPDES Permit No. NC0025305 to discharge 70,200
gallons per day of treated effluent to an unnamed tributary of Morgan Creek
in the Cape Fear River Basin. The Permit expires on July 31, 1993. The
University desires to renew the Permit in accordance with North Carolina
General Statute 143-215. The University requests that the Permit be
modified to: 1) combine the stormwater and wastewater discharge into one
NPDES Permit; 2) increase the flow allowance from 70,200 gpd to 92,234 gpd;
and, 3) Eliminate Discharge Point No. 001 from the Permit.
Sampling for the priority pollutants, in accordance with CFR 40, Part
122.21, has been performed; however, results were not available prior to
the submittal deadline of January 31, 1993. These results are currently
being analyzed for priority pollutants and will be forwarded to NCDEM as
soon as they are received.

The ’’weekly average discharge” is defined as the total mass of
all daily discharges sampled and/or measured during the calendar week
(Sunday-Saturday) on which daily discharges are sampled and measured,
divided by the number of daily discharges samples and/or measured
during such week. It is, therefore, an arithmetic mean found by
adding the weights of pollutants found each day of the week and then
dividing this sum by the number of days the tests were reported. This
limitation is identified as "Weekly Average.” in Part I of the permit.
Mass/Day Measurements
The “monthly average discharge: is defined as the total mass of all
daily discharges sampled and/or measured during
which daily discharges are s<
of daily discharges samples and/or measured during such month. It is
therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by
the number of days the tests were reported. The limitation is
identified as ’’Daily Average" or "Monthly Average” in Part I of the
permit.
The "maximum daily discharge is the total mass (weight)~of a
pollutant discharged during a calendar day. If only one sample is
taken during any calendar day the weight of pollutant calculated from
it is the "maximum daily discharge.” This limitation is identified as
"Daily Maximum,” in Part I of the permit.
The "average annual discharge" is defined as the total mass of all
daily discharges sample and/or measured during the. calendar year on
which daily discharges are sampled and measured, divided by the number
of daily discharges sampled and/or measured during such year. It is,
therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the year and then dividing this sum by the
number of days the tests were reported. This limitation is defined as

The "average annual concentration," other than for fecal coliform bacteria,
is the sum of the concentrations Of all daily discharges sampled and/or
measured during a calendar year on which daily discharges are sampled and
measured divided by the number of daily discharges sampled and/or. measured
during such year (arithmetic mean of the daily concentration values). The
daily concentration value is equal to the concentration of a composite
sample or in the case of grab samples is the arithmetic mean (weighted by

The "average weekly concentration,"
is the sum of the concentrations of all daily discharges sampled and/or

Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the
respective flows.
Arithmetic Mean: The arithmetic mean of any set of values is the summation
of the individual values divided by the number of individual values.
’’instantaneous flow measurement"
of sampling, when both the sample and flow will be representative of the
total discharge.
Composite Sample: These samples consist of grab samples collected at
equal intervals and combined proportional to flow, a sample continuously
collected proportionally to flow, or equal volumes taken at varying time
intervals. If a composite sample is obtained from grab samples, the
following requirements apply. The intervals between influent grab
samples shall be no greater than hourly. Intervals between effluent grab
samples shall be no greater than hourly except where the detention time
of the. wastewater in the facility is greater than 24 hours, in which
case, the interval between grab samples shall be no greater in number of
hours than the detention time in number of days; provided, however, in
no case may the time between effluent grab samples be greater than six
hours nor the number of grab samples less than four during any discharge
period of 24 hours or less.
Grab Sample: Grab samples are individual samples collected over a
period of time not exceeding 15 minutes; the grab sample can be taken
manually.
Geometric Mean: The geometric mean, of any set of values is the Nth root of
the product of the. individual values where N is equal to the number of
individual values. The geometric mean is equivalent to the antilog of
the arithmetic mean of the logarithms of the individual values. For
purposes of calculating the geometric mean, values of zero (0) shall be

This letter shall serve as Notice of Intent for the University of North
Carolina to combine the stormwater discharge with the existing wastewater
discharge NPDES Permit No. NC0025305 for the referenced site. Per your
recommendation, the University will request a modification to the existing
permit with the permit renewal request. The modification will request the
inclusion of the stormwater discharge with the wastewater discharge since
they leave the site from a single outfall. The existing wastewater permit
expires on July 31, 1993.
Enclosed for your review is the supporting documentation describing the
stormwater characteristics of the boiler plant site. Included are narrative
descriptions, the stormwater sampling proposal, lab analysis results, and
various drawings. It is our understanding that EPA Forms 1 and 2F are not
required since the stormwater discharge permit will be combined with the
existing wastewater permit.

UNIVERSITY OF NORTH CAROLINA
University Boiler Plant
1]
The facility is a coal fired steam boiler, power generation plant that
serves the University of North Carolina campus at Chapel Hill. The plant
site is approximately 11.5 acres in size and is located between Cameron
Avenue and McCauley Streets east of the intersection of Robertson Street
with Cameron Avenue. The plant consists of a boiler building, turbine
generator building, coal silos, above-ground fuel oil and miscellaneous
tanks, bag-house structures, a coal storage structure, an ash silo, a
laundry facility, and various drives and parking areas.
Approximately 65% of the site consists of impervious surfaces in the form
of buildings, paved drives, parking lots, and storage areas. The remainder
of the site is comprised of lawns and landscaped areas. In general, the
site slopes approximately 3% from north to south toward McCauley Street.
Stormwater runoff throughout the site is collected separately by an
industrial waste collection system and a storm drainage system. Runoff
collected in the industrial waste system is treated on site and combined
with the stormwater at a common structure and is discharged under McCauley
Street in a 60" concrete pipe. The pipe discharges into an un-named
tributary approximately 3,000 feet north of Morgan Creek.
The industrial waste collection system is used to collect and treat plant
wastewater including runoff exposed to potential pollutants during the
normal operation of the power plant. The industrial system collects runoff
from the following areas: long term coal storage area, coal silos, coal
handling areas, containment area of fuel oil storage tanks, ash silo, and
floor drains of the boiler and turbine generator buildings.
Various nonstormwater cross-connections exist between the industrial waste
system and the storm drainage system to facilitate the plant operation.^The
cross-connections are described in detail in the section
"Nonstormwater Connections".
The wastewater treatment system removes solids and adjusts pH to between 6
and 8. The system consists of two settling tanks, a caustic rapid mix tank,
an acid rapid mix tank, a chemical feed system, and a metering manhole. The
treatment system is operated in compliance with the standards established
by existing NPDES Permit No. NC0025305. The NCDEM is currently reviewing a
Special Order by Consent SOC 89-70 AD II, requiring the addition of an
equalization basin to the treatment facility on site. The basin has been
constructed and is currently undergoing inspection prior to operation.
During the site investigation by Greenhorne & O'Mara, recent heavy rains
were causing the existing treatment facility to overflow through a
temporary line bypassing the equalization basin discharging to a surface
channel leading to Structure C-0. Completion of the equalization basin will
allow storage of overflow runoff from the wastewater treatment plant from a
10-year frequency storm.
Stormwater runoff not collected by the industrial waste system is collected

Fuel oil is used as a back-up fuel for the boiler and is stored in above-
ground tanks surrounded by concrete containment walls. The oil
delivered by truck and is transferred to the tanks by exposed pipe.
The site sanitary sewer system discharges to the municipal system provided
by the Orange Water and Sewer Authority (OWASA). The OWASA connection is
located in McCauley Street at the southwest corner of the property. No
sanitary sewage treatment occurs at the site.
Ash from the boiler building is transferred from the baghouse to the ash
silo in a pneumatic transfer system. Ash is loaded from the silo into dump
trucks several times a day and transported off-site. The truck loading
occurs in an enclosed area below the ash silo. Runoff from the area
surrounding the ash silo is collected by the industrial waste system via
surface inlets.
by surface inlets and roof drains throughout the site and flows through
storm drainage systems A,C,E and F, as indicated on the Drainage Plans.
Systems A and F each discharge to normally dry stormwater retention ponds
containing mechanical outlet valves. The outlet valves are adjustable and
can control the pond discharge into underground pipes. The pond discharge
pipes lead to Junction Box C-0 immediately north of the property line
adjacent to McCauley Street, where the treated industrial waste effluent
and pond discharge commingle prior to discharge from the site. The
retention ponds were designed to collect the first inch of runoff as
required by the Special Use Permit issued by the Town of Chapel Hill,
permitting the addition of the new plant to the site.
Approximate drainage areas were determined from the Drainage System Plans
and on-site visual inspections of each drainage system. The Drainage Maps
enclosed were produced from this information.
The long term coal storage area appeared to have some recent runoff, from
the entrance to the storage area, that flowed to Structure C-4. Coal had
also overtopped the south wall and spilled down the slope. Runoff from
both of these areas would enter the storm drainage system with no
treatment. The potential for contamination does not appear to be
significant, however, as neither circumstance involves a large amount of
runoff nor occurs on a regular basis.
Coal and limestone are received via rail car and are bottom loaded from the
rail cars to a conveyor inside the unloading building. The coal is
transported through an above-ground conveyor to the crusher building, coal
silos, or long term coal storage area. An underground pneumatic transfer
system is used to transport the coal to the boiler building. Limestone is
bottom loaded from the rail cars directly into an underground pneumatic
system and is stored in the boiler building. Runoff from the coal handling
and storage areas is collected by the industrial waste system via surface
inlets.

are connected to both the stormwater and industrial waste system as
described below.
To facilitate various plant operations, nonstormwater connections to the
storm drainage system exist at the cooling tower, cooling water return
line, city water surge tank and at the fuel oil tank containment area. The
connections are controlled with valves and are monitored by plant personnel
on a regular basis. The connections are summarized as follows:
An open general storage area is located west of the new boiler building and
is used for storage of miscellaneous items including the following:
surplus pumps and equipment; scrap lumber; scrap metal, valves; empty drums
Numerous chemicals are used in the normal operation of the plant. None are
exposed to stormwater under normal conditions, however, with the exception
of those mentioned above. The industrial waste system collects floor
drains, storage areas, and surface runoff from areas of the site exposed to
potential pollutants.

These areas
However, the
presence of the general storage area and the cross-connections to the plant
operations may require an additional NPDES Stormwater Discharge Permit.
Greenhorne & O'Mara will consult the N.C. Division of Environmental
Management, Water Quality Section (NCDEM), to present the data gathered to
date and confirm the requirement for an NPDES Stormwater Permit based on
the information contained herein.
Construction activities are underway in two areas of the site: demolition
and renovation of the old power plant building and the addition of a
concrete equalization basin to the wastewater treatment plant. Erosion
control devices were observed along the southern property line in the area
of the equalization basin. The area encompassing the demolition work
drains into Storm Drainage System A and into a retention pond. As this
construction began prior to the October 1, 1992 Permit deadline, it is our
understanding that no Permit will be required for the construction
activity. The total area of the remaining construction is approximately
one acre.
The site stormwater runoff exposed to potential pollutants through normal
plant activities is collected and treated on-site by the industrial waste
system and is regulated by existing NPDES Permit No. NC0025305. The
remainder of site runoff is collected in the storm drainage system and
discharged into two retention ponds.
quality controls if necessary.” Typical BAT practices in North Carolina
consist of wet retention ponds, infiltration trenches, vegetated swales,
vegetated buffer strips, oil/grit separators, source controls, and
management practices. The site retention ponds and the industrial waste /
wastewater treatment system are accepted methods of "best available
technology".
Additional stormwater controls for the site are not anticipated if an NPDES
Permit is required. The NCDEM may require a change in housekeeping
procedures, however, to discourage the continued storage of empty chemical
drums exposed to rainfall. The extent of any required BAT practices to be
implemented will be determined through discussions with NCDEM as the Permit
Application progresses.
Should a Permit be required, the NCDEM has indicated in preliminary
memorandums that the Discharge Permits must "contain technology based
controls based on best available technology (BAT) considerations or water
quality controls if necessary."

The UNC Boiler Plant is being assisted with the permit application by Greenhome & O’Mara
(G&O) and TEA, Inc.. Each stormwater conveyance has been evaluated to determine the
outfall’s association with industrial activity and the most appropriate sampling approach. To
comply with the intent of the legislation and maintain scientifically acceptable data, a
sampling approach has been developed for the Boiler Plant and is outlined in this document.
The November 1990 Final Rule specified that the samples of storm water taken at each
outfall be sampled as a composite sample in a flow proportional manner and as a grab
sample collected in the first 30 minutes of rainfall. The rain event must be at least 0.2
inches, but less than 0.8 inches and more than three hours in duration to be consistent with
average rainfalls in this region of North Carolina. There must also be an interval of at least
72 hours since the previous rainfall of more than 0.1 inches.
The sampling approach discussed considered several options. Initially, it was considered that
the retention ponds would be representative of the storm water discharge and samples could
be grabbed from the ponds. The site investigation revealed that some storm water drainage
ties in to the system below the ponds, thus disqualifying the ponds as final sampling points.
i.
The Boiler Plant at UNC Chapel Hill has a storm drainage system that controls runoff from
the Site. This system includes two retention ponds. The Site also has an industrial waste
drainage and stabilization system that includes a conveyance system, an oil/water separator, a
treatment system, and an equalization basin. This waste system has an existing NPDES
permit to discharge wastewater. Both the stormwater drains and the wastewater outfall leave
the property on the south side through a 60 inch pipe under McCauley Street into a tributary
of Morgan Creek. A detailed discussion and maps of the Site are included in Greenhome &
O’Mara’s "Summary Memorandum" outlining the full Site Investigation published July 2,
1992.
l-.P- '
The November 1990 Final Rule for NPDES Permit Application Regulations for Storm Water
Discharges applies to the Boiler Plant Site at the University of North Carolina at Chapel Hill,
NC. A formal application for a storm water discharge permit is required to be submitted to
the State of North Carolina. As part of the permit application, the University of North
Carolina (UNC) must provide quantitative data from storm water discharges associated with
industrial activity. The storm water discharges must be sampled at each outfall that is a
conveyance for storm water and discharges directly to the waters of the United States.

r '
The eastern half of the Boiler Plant Site could be considered segregated from industrial
activity due to the configuration of the storm drains, the industrial wastewater system, and
the activities at the Site. Therefore, it was considered that the appropriate sampling point
would be the manhole designated as "Manhole C-l" on the G&O Site Map. This had the
advantage of limiting the testing to that portion of the discharge that could be attributed
directly to storm water associated with industrial activity. The disadvantage of this sampling
approach was that a site with a single outfall for storm water and wastewater would be
sampling and testing two different permits.
The conclusion reached was that a single combined sampling approach should be taken at the
outlet side of "Structure C-0" representing the combined storm water and wastewater from
the entire site. This approach would provide a single representative measure of the impact of
the site on the receiving waters and consolidate the permit management required by the UNC
Boiler Plant. This would also reflect any illicit connections by virtue of the fact that whether
the wastewater or process water were discharged through the industrial wastewater system or
through the storm water system the impact would still be measured at the sampling point.
It is our proposal that the sampling and testing of storm water discharges associated with
industrial activity from the UNC Boiler Plant for NPDES permit application should be
conducted from the outlet portion of "Structure C-0" as identified on the G&O Drainage
Area Map. The sample will be collected in accordance with the sampling requirements
specified in 40 CFR Part 122 and outlined in Section II of this proposal. A grab sample will
be collected in the first 30 minutes of rainfall and a flow proportional composite will be
collected for the entire rainfall.
It is also proposed that a grab sample be taken from the inlet of the offsite residential
drainage and that the sample be analyzed for the same list of parameters as the "C-0"
sample. Additionally, it is proposed that the flow of the residential drainage be determined.
Table 1 details the recommended parameter list based on the Federal requirements and the
site activities detailed in the "Summary Memorandum "/Site Investigation.
A complicating factor in this conclusion was the impact of waters draining to the site from an
offsite residential neighborhood of 15'acres. This drainage enters the site from the east and
connects to the storm drainage system at "Structure E-l". The impact would be measurable
at the sampling point of "Structure C-0". Taking this into consideration, it was decided that
a grab sample from the inlet above "Structure E-l" should be taken to evaluate the impact of
this neighborhood on the storm water discharge from the UNC Boiler Plant at "Structure
C-0".

and to briefly review the permit requirements as they relate to the boiler
plant site.
Mr Garceau stated that information obtained from Coleen Sullins of the
NCDEM central office indicated that the University is not exempt from the
Stormwater Program due to its status as an educational facility, nor does
the State have plans to create a General Permit for steam power plants.
Based on the above, all agreed that an Individual Permit would be required
for the Boiler Plant site.
Mergner confirmed with Mr. Heirs that the plant's size of 250,000,000

Mr. Bondor noted that existing mapping
off-site drainage crosses the property,
field to determine the need for sampling.
Mr. Bondor suggested that a second meeting with NCDEM be conducted to
present the Summary Memorandum and discuss the proposed Sampling Plan, Mr.
Heirs agreed.
Mr. Heirs also agreed that an informal review of a "Draft Application" by
the DEM Regional Office could be conducted to eliminate minor discrepancies
and avoid resubmittal of the final Permit Application.
Mr. Mergner reminded G&O of the University^ request for a description of
future sampling requirements and sample collection methods to be included
in the Project Scope of Services.
Mr. Garceau asked about the possible conditions of the Permit. Mr. Heirs
reported that the NCDEM has not received nor approved many Permit
Applications to date, and could not predict the Permit conditions. He
stated that it could be assumed the Permit will be similar to the Boiler
Plant process Wastewater Permit since they discharge to the same stream.
Mr. Bondor noted the possibility of no industrial activity occurring within
the drainage areas of the site storm drain system. Mr. Mergner confirmed
that the plant design included an "industrial waste" drainage system that
is intended to collect all runoff exposed to industrial activities. This
system is regulated under the NPDES Wastewater Program (Permit No.
NC0025305). Should the site investigation indicate no additional
industrial activities are present within the remaining storm drainage
system, an additional NPDES Permit may not be required.
Mr. Garceau requested that DEM forward a Permit Fee Schedule to G&O.
Mr. Mergner reported on the construction status of the new boiler plant:
the new facility is operational; minor modifications within the old boiler
will be completed in a few weeks and will be followed by decommissioning of
the old boiler this summer; a few accessory buildings and small parking
areas may not be completed at the time of the Permit Application, however.
G&O will note the construction status on the Permit Maps.

require sampling of off-site drainage; however, the University may consider
it should pollutants be suspected from a source off-site. The samples
would be collected where the off-site flow enters the University property
to identify pollutants, if any, which may be entering the University
property from the off-site area.

Mr. Mergner reminded G&0 to consider the intended design function of the
retention ponds and how they could affect the content of the stormwater
discharge.
Mr. Mergner reported on the status of a pending Special Order by Consent
for violations to the discharge limits of the existing NPDES Permit. The
SOC has been executed by the University but remains under review by the
NCDEM. An equalization basin is under construction at the plant as
required by the SOC. The pending SOC should not affect the Stormwater
NPDES Permit Application if the samples can be collected upstream of the

The meeting was held to discuss issues associated with the renewal of the
NPDES wastewater permit.
Mr. Dixon indicated that he had briefly talked with Coleen Sullins and Kent
Wiggins of the North Carolina Division of Environmental Management (NCDEM)
concerning the project and the time schedule for submitting the permit
renewal application package. Mr. Wiggins stated that the University would
be treated no differently than any other permit holder. Every effort
should be made to submit the application package prior to 180 days before
the existing permit expires. Mr. Wiggins stated that a partial submittal
should be made if all data is not available. He also agreed that if would
be worthwhile for the University to submit a letter prior the 180 deadline
informing NCDEM of its ongoing efforts to submit the renewal package
including implementation of recommendations to improve the facility. Mr.
DuBose agreed that the University would submit such a letter. Ms. Sullins
stated that only one 24-hour composite for the Priority Pollutant List is
required; however, she noted that certain parameters would need to be
sampled by grab rather than composite in accordance with 40 CFR 122.21.
The attendees discussed when the sampling should be performed. It was

Mr. Mills agreed that the stormwater and wastewater flows should be
combined into one NPDES discharge permit.
Mr. Garceau stated that G&O's work for the University on the stormwater
source identification and monitoring should provide the basis for inclusion
in the framework of the NPDES permit.
Mr. Mills indicated that the normal flows are treated industrial effluent
only, i.e., dry weather flows. Wet weather flows are determined by
periodic monitoring during storm events. DEM is looking for indicator
parameters such as visual monitoring on a semi-annual basis and sampling
once a year.
Mr. Dixon introduced the meeting to discuss the NPDES Wastewater Permit
Renewal for the UNC Boiler Plant Wastewater Treatment System,

Cashion stated that because of the nature of the pH measurement it
cannot be averaged and therefore must be reported as a daily maximum and
minimum.
Mr. Dixon asked if it would be possible to report temperature and pH as a
daily average rather than reporting every spike as is now done as a result
of the continuous monitoring now being performed.
Mr. Mergner stated that the pH monitoring at the plant was probably as good
as any system in North Carolina. The data is retrievable through the
plant's electronic data storage system.
Mr. Cashion stated that most of the compliance problems seem to be related
to pH.
Mr. Mergner commented that maintenance of the pH monitoring probes also add
to the problem.
Mr. Mergner stated that the University has made considerable progress in
treating the wastewater from the boiler plant. At this time there are
three areas that continue to pose problems in meeting the effluent limits.
They are 1) temperature, 2) pH, and 3) excessive Iron. The University is
presently analyzing the current operations in an effort to correct these
problems. Possible remedies include diversion of flow and proposed
modifications. It is felt that significant improvements can be made by
implementing the proposed modifications.
Mr. Dixon asked what is required to show need for additional discharge,
stated that the University would like to obtain an increase in the flow
limit if possible.
Mr. Roach noted that many times the spikes that are recorded occur when
the maintenance staff is working out operation problems.
Mr. Mills said he did not expect it to be a problem; however, DEM will
require an engineering evaluation to ensure that the treatment system is
capable of treating any increase in flow. Mr. Mills said that the increase
in flow should be requested during the renewal, otherwise a public hearing
