Dear Mr. Cornwell:
Division personnel have reviewed and approved your application for renewal of the
subject permit. Accordingly, we are forwarding the attached NPDES permit. This permit is
issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandurn of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007 (or as subsequently amended).
The final permit contains the following changes from your previous permit:
• Following the Mercury Permitting Guidance for the implementation of the Statewide
Mercury TMDL mercury data was reviewed to determine the need for a limit or a
Mercury Minimization Plan. A Mercury Minimization Plan will be required, see Special
Condition A. (4) for requirements.
• As a result of a reasonable potential analysis the limit and monitoring for nickel was
eliminated from the permit as well as monitoring for zinc.
If any parts, measurement frequencies or sampling requirements contained in this permit
are unacceptable to you, you have the right to an adjudicatory hearing upon written request
within thirty (30) days following receipt of this letter. This request must be in the form of a
written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed
with the Offe of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina
27699-6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The
Division may require modification or revocation and reissuance of the permit. This permit does

A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 17%.
The permit holder shall perform at a minimum, quarterlq monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. The tests will be performed during the months of
February, May, August and November. These months signify the first month of each three month
toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained
during representative effluent discharge and shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3
(original) is to be sent to the following address:
Attention:
North Carolina Division of Water Resources

1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring
will be required during the following month. Assessment of toxicity compliance is based on the toxicity
testing quarter, which is the three month time interval that begins on the first day of the month in which
toxicity testing is required by this permit and continues until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT

The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is

October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.

grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and (j) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40
CFR 403.5(a)(1)]
b. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibitions against the
introduction of the following wastes in the waste treatment or waste collection system [40 CFR 403.5(b)]:
(1) Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to,
wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade
using the test methods specified in 40 CFR 261.21;
(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause Interference with the POTW;
Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
(3)
(5)
(7)
(8)
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the
discharge has not ceased, the anticipated time it is expected to continue; and steps taken or planned to reduce,
eliminate, and prevent reoccurrence of the noncompliance,

Mercury Evaluation
A mercury evaluation was conducted in accordance with the Permitting Guidance developed for
the implementation of the statewide Mercury TMDL to determine the need for a limit and
Mercury Minimization Plan (MMP). Based on dilution the water quality based effluent limitation
(WQBEL) for mercury is 69 ng/1 while the TBEL is 47 ng/1. No limit will be implemented since
the annual averages are below both WQBEL and TBEL. Mercury was detected above 1 ng/1
therefore a Mercury Minimization Plan will be required in the permit. A condition will be added
to the permit describing the requirements for the MMP.

Reasonable potential analysis (RPA) was performed for arsenic, cadmium, copper, nickel,
cyanide and zinc. Copper and cyanide showed reasonable potential to exceed the allowable
limits. Daily maximum and monthly average limits will be implemented for cyanide. Monitoring
for zinc will be eliminated from the permit. Limits and monitoring for nickel will also be
eliminated from the permit. See attached RPA spreadsheet for details.
INSTREAM MONITORING:
The permit wis modified on August 12, 2013 to modify the instream requirements. Previously
the permit required one upstream sampling location and two downstream sampling points.
One downstream sampling point was eliminated due to difficulties in access to the sampling
point. Instrean data shows dissolved oxygen and temperature values within the water quality
standards.

Process Flow Description
The First Broad WWTP is a 6-mgd facility operated by the City of Shelby which discharges treated
MR effluent to the irst Broad River. Influent wastewater enters the plant through a gravity feed sewer line
and passes through coarse manual and fine mechanical screens and a grit classifier. Grit slurry is
,I
dewatered by an auger type classifier and is deposited into a dumpster for disposal at landfill. Following
preliminary treatment, the flow enters the main lift station. Four influent pumps lift the influent flow to a
splitter box andl the flow is split to two primary clarifiers. Settled solids are removed by pumps located in
the primary sludge pump station, where they are pumped to the Aerated Sludge holding tank. Wastewater
carries on to either the trickling filters or the aeration basin. Currently operation of the plant does not
include the uselof the trickling filters.
I
The primary clarifier effluent enters the aeration basin and combines with the return activated sludge
(RAS) in the first cells of the parallel biological treatment trains. The activated sludge system consists of
1.5 MG aeration basin and blowers. The aeration basin consists of six cells with arrangement to either be
I
operated in series or parallel. Mixing and aeration are provided through a jet pod aerator each cell. Three
II
cells use mixed flow propeller pumps and three cells use submersible pumps. Four positive displacement
blowers have acombined capacity of 2,400 cfm are used for aeration.
Four final clarifiers provide separation of the mixed liquor suspended solids (MLSS) generated in the
activated sludge basins. The return activated sludge (RAS) is pumped by two RAS pump stations for
return to the activated sludge basin. Waste Activated Sludge (WAS) is metered and pumped to two
gravity thicke rs for thickening. Water is sent back to the primary clarifiers and thickened sludge is
pumped to the aerated sludge holding tank.
The plant uses chlorine and sulfur dioxide for disinfection/chlorine removal at the effluent. Two
compartment contact tank provides detention time for reactions to occur.
it
The sludge management system includes the aerated sludge holding tank, dewatering by belt presses
and a composting facility. More details are in the sludge management plan.
The plant is equipped with back-up generation of 2000KW generator which provides back-up generation
to the whole plant. In 2012, the City relocated a generator to provide more redundancy to the main lift.
This generator is 175 KW.

Sludge Management Plan
for
First Broad Wastewater Treatment Plant
NPDES Permit # NC0024538
The First Broad Wastewater Treatment Plant (WWTP) design for sludge handling consists of sludge
dewatering and composting. This plan describes the processes in place for treating and disposing of this
material.
WASTEWATER PROCESS
The First Broad WVVTP is a 6.0 MGD Biological Activated Sludge Wastewater Treatment Facility. The
process consists of a Barscreen, cylindrical fine screen, grit removal, two primary clarifiers, two trickling
filters (currently out of service), aeration basin, four secondary clarifiers, chlorination/dechlorination,
sludge holding tank with aeration, compost building (dewatering included). The Facility discharges into
the First Broad River, which is a Class C stream in the Broad River Basin.
RESIDUALS CHARACTERISTICS
The First Broad River WWTP operates a Compost Facility equipped with IPS /Wheelabrator (US Filter)
equipment and technology. Source of the residuals processed through the facility is from primary and
secondary residuals produced by the 1NV TP with a very small percentage of digested WAS sludge
processed for the Town of Boiling Springs. The primary sludge is pumped to the sludge holding tank at a
solids concentration of about 4%. WAS sludge is thickened by gravity to about 3% solids prior to being
blended in the sludge holding tank with the primary sludge.

50ft/210,000 gals
RESIDUALS DE -WATERING
Sludge is stored in the Sludge Holding tank and aerated using a combination of three (3) blowers housed
in the blower building adjacent to the sludge holding tank.
When operating the blended sludge is conveyed to one of two (2) meter Roediger Tower Presses by one
of three Moync positive displacement pumps, prior to being deposited on the press the sludge is mix with
polymer through the use of an in line velocity mixer. The sludge reaches the press at about 3% to 5%
solids content. (After dewatering through the press, the finished cake is about 18% to 23% solid content.
AMENDMENT PROCESSING
The City of Shelby's Public Works Department gathers "Yard Waste" throughout the city; this material is
delivered to the Composting Facility. Cleveland County also provides yard waste from some of their
collections sites. After delivery the yard waste (brush) is feed through a "Diamond Z tub grinder equipped
with a set of 3X 5 screens which produce a ground material from saw dust to pieces roughly as large as
2 to 5 inches in length. This material is transported into a covered area of the compost building where
there is approximate room for 2 weeks storage.

IAA
Met
1
COMPOST MIXING
After discharge rom the press the dewatered sludge travels a conveyor and is deposited into a mixing
area where it is mixed with amendment using a skidsteer. The Compost mix is dependent on the moisture
content of the amendment. A "Normal" mix is based on a 1:1 ratio by weight (approx. 30% sludge and
70% amendment by volume). From the floor the mix is transported to the "bays" by the use of a "Skid
Steer Loader. The "Load Zone" for each bay is an area 6' X 6' X 12', or about 16 cu. yds. The mix enters
the bay at about160% moisture and 40% solids content.
COMPOST PROCESS
The Compost Process is a 21-Day In -Vessel Aerated Static Pile Process that consists of ten (10) vessels
(bay) 6' wide and 180' long. There are two (2) Agitators, one each for five (5) bays. The agitator travels
down the length Hof the bay in an "UP" position after reaching the far end it "LOWERS" the drum and starts
its travel back up the bay. As the agitator travels through the material, the drum pitches the mix back onto
a conveyor that discharges about 12' behind the drum. This action basically moves all the material 12'
down the bay. Throwing the first material (finished compost) it comes in contact with out of the bay,
moving the rest down and after completing its travel back up the bay, creating an empty "Load Zone" for
the next material to go into.
After the material is discharge from the bay and prior to distribution as finished compost, it is sampled for
Fecal Coliform a d is stored inside (covered) for 30 days while awaiting test results.
LEACHATE COLLECTION
Decant from th i� belt presses and leachate for the collection/piping system on the vessels is collected
from the system and drains to a manhole located outside the Compost facility. The manhole is equipped
with two pumps that are used to pump the leachate back to the primary clarifier splitter box.
AERATION AND TEMPERATURE CONTROL
In each bay the are 4 zones (A, B, C, D) each zone has a series of perforated pipes underneath a stone
plenum that is connected to an air blower. The zones are monitored by thermocouples mounted in the
common walls between bays. The blower system monitors on a "TIME - TEMPERATURE" bases. If the
temperature in the bay reaches a set point the blow comes on and runs until it reduces the temperature in
that zone. If the temperature does not reach the set point within one hour, the blower comes on for one
minute to help discharge the moisture from the mix in each zone.
DISTRIBUTION
Compost generated at the First Broad WWTP is currently distributed to the public (landscapers and
homeowners) during the week and on weekends. The City provides the free compost as an unbagged
bulk product that is loaded for customers at no charge.
ODOR CONTROL
The compost building is equipped with five (5) 50 HP exhaust blowers that discharge the air and moisture
from inside thOuilding through a series of large perforated pipes to the atmosphere, after passing
through a "BIO-FILTER". The bio filter is basically a static compost pile approx. 4 feet deep. The air from
the building passes through this organic material prior to escaping to the atmosphere. This material strips
the odor from the air as it passes through. The moisture helps with the .biological process taking place in
the static compost.
