SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
complete.

Process Flow Description
The First Broad WWTP is a 6-mgd facility operated by the City of Shelby which discharges treated effluent
to the First Broad River. Influent wastewater enters the plant through a gravity feed sewer line and passes
through coarse manual and fine rotary mechanical screens and a grit classifier. Grit slurry is dewatered by
an auger type classifier and is treposited 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 and
the flow is split to two primary clarifiers. Settled solids are removed by positive displacement pumps located
in the primary sludge pump station, where they are pumped to the Aerated Sludge holding tank. Wastewater
carries over the primary clarifier weirs to a splitter box. Prior to the splitter box Return Activated Sludge
(RAS) is pumped back to a manhole where it mixes with primary effluent. The splitter box diverts flow to
one of the three aeration basins.
The aeration basin system consists of a total volume of 2.25 MG aeration basin and three Turblex blowers.
Each aeration basin consists of an anoxic section that has three cells with submersible mixers. Each
aeration basin four aerobic zones with fine bubble diffusers. The Turblex blowers can operate between
1,600 -3,550 scfm to provide air to the aeration system. Each of the three basins have an internal recycle
pump located in the last aerobic zone of each basin with a rated capacity of 4,166 gpm. These pumps have
VFDs that adjust using the incoming flow to the WWTP by the SCADA system.
After the aeration basins, flow is split between four (4) final clarifiers. The clarifiers provide separation of
the mixed liquor suspended solids (MLSS) generated in the aeration basins. The return activated sludge
(RAS) is pumped by two RAS pump stations for return to manhole upstream of the aeration splitter box.
Waste Activated Sludge (WAS) is metered and pumped to a 40 ft diameter gravity thickener 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.
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 2000 KW generator which provides back-up generation
to the whole plant. In 2012, the City relocated a 175 KW generator to provide more redundancy to the
main lift.

Sludge Management Plan

Sludge Management Plan
First Broad Wastewater Treatment Plant
NPDES Permit # NCO024538
Compost Permit # WQ0007780
The First Broad River 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 WWTP 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, three (3), aeration basins,
four secondary clarifiers, gravity sludge thickener, chlorination/dechlori nation, sludge holding tank with
aeration, and compost facility which includes dewatering and filtrate equalization. The WWTP 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. Primary and secondary residuals produced by the WWTP are processed through the
facility 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 3%. WAS sludge is
thickened by gravity to about 2% solids prior to being blended in the sludge holding tank with the primary
sludge.

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 Moyno positive displacement pumps, prior to being
deposited on the press the sludge is mixed 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 20-25% solids 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. After delivery the yard waste (brush) is feed through a "Diamond Z tub
grinder equipped with a set of 3 X 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 room for approximately 2 weeks of storage.
COMPOST MIXING
After discharge from the press the dewatered sludge travels a conveyor and is deposited into a mixing area
where it is mixed with amendment using a skid steer. The compost mix is dependent upon the moisture content

Sludge Management Plan
First Broad Wastewater Treatment Plant
NPDES Permit # NCO024538
Compost Permit # WQ0007780
of the amendment. A "Normal" mix is based on a 1:1 ration by weight (approx. 30% sludge and 70%
amendment by volume). From the floor the mix is transported to the "bays" by the use of the skid steer. 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 about 60%
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
of 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 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 and is stored inside (covered) for 30 days while awaiting test results.
COMPOST STORAGE
The finished compost is stored inside (covered) for 30 days. Additional uncovered storage area on a cement
pad on site for approximately 90 days storage.
LEACHATE COLLECTION
Decant from the 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 to two 40,000 gallon (each) flow equalization tanks. The filtrate and
leachate is then metered back to the primary clarifier splitter box.
AERATION AND TEMPERATURE CONTROL
In each bay there 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 blower 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). The City provides the free compost as an unbagged bulk product that is loaded for customers at
no charge. Upon distribution the customer is provided Utilization Agreement information. Records of
distribution including customer information and quantities are kept on site.
ODOR CONTROL
The compost building is equipped with five (5) 50 HP exhaust blowers that discharge the air and moisture from
inside the building 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.
