Compliance Evaluation Inspection
Town of Clayton - Little Creek Water Reclamation Facility
NPDES Permit Number NC0025453
Stormwater Permit Number NCG110080
Johnston County
The 2.5 MOD water reclamation facility consists of the following units: influent head works with a
FRP cover system with a biofilter odor control system with mechanical screening and a vortex
type grit removal system; influent pump station with ultrasonic flow meter with back-up float
alarm; a 214,500 gallon anaerobic basin in front of oxidation basin # 2; a 300,000 gallon anoxic
tank in front of oxidation basin # 2; a 200,000 gallon anoxic in front of oxidation basin # 1; three
(3) secondary clarifiers; two shallow bed DAVCO traveling bridge type tertiary filters; UV
disinfection with back-up chlorination / dechlorination; effluent pump station; one 90,000 gallon
aerated digester/sludge stabilization tank; two - 360,000 gallon sludge holding tanks; sludge
loading station; a sludge thickening building containing a rotary drum thickener; sludge drying
beds; in-plant non-potable water system using reclaimed treated wastewater; a reclaimed water
pump station and transmission force main to the Pine Hollow Golf Course and two on-site
generators to provide back-up power. The clarigester, trickling filter, and secondary clarifier of
the original plant are not in use and are abandoned.
At the time of inspection, sludge from the newer aerated sludge holding tank was being pumped
into the other aerated sludge holding tank which was approximately 80% full. Sludge volume in
the other sludge aerated tank was approximately 50% full. All aerators in both sludge holding
tanks were operational. Sludge was being thickened in the rotary drum thickener. Sludge is
expected to be hauled in the next 7 days. Influent in the two oxidation basins was light to
medium brown in color with very little foam. Covers have been placed over the anaerobic
selectrr to prevent odor. All mixers in the anaerobic sections of both basins were operational

e. Stormwater Outfall 005 receives stormwater flow from the area around the influent
pump station and the reclaimed water pump station. Combined flows discharge to a
low-lying area east of the influent pump station. Water at the discharge point
appeared clear.
f. Stormwater Outfall 006 is located near the tertiary filter structure. The drainage area
around the return sludge pump and secondary clarifier number 1 and 2 discharge into
outfall 006. At the time of inspection a sediment trap had been constructed from crushed
stone in front of the discharge point. Outfall 006 discharges into a wooded area. There
was no discharge at the time of inspection.
I would like to thank James Warren and Leigh Honeycutt time and assistance with this inspection. If
you have any questions about this report or the inspection, please contact me at 919.791.4261.
d. Stormwater Outfall 004 receives flow from the parking lot and in front of the operations
building. The discharge point is across the street into a small ditch. Water in the ditch
appeared clear.

Introduction:
Process Description
The sludge conditioning and disposal systems consist of: two drum thickeners (80 gpm &
300 gpm), polymer flocculation, two .36 mg aerated holding tanks, one .09 mg aerobic
digester, and sludge transfer pump.
The plant consists of a mechanical and manual bar screen, Jeta (Vortex) type grit removal
system, 9 inch parshall flume with flow meter, and a composite sampler. The influent
pumping station has three 60 hp dry pit submersible pumps and one 40 hp pump.
Biological nutrient removal is achieved by a Carrousel Denite R System (Eimco), the
system contains an anaerobic selector, two anoxic tanks, and two oxidation ditches. The
biological system is controlled by a PLC based control system that monitors oxygen
throughout the system. The plant also has three circular clarifiers, two mixed bed tertiary
filters, ultraviolet disinfection, effluent pumping station, in plant reuse pumping system,
and a reclaim water pumping station. In addition to the biological systems, the plant has
chemical feed for alkalinity (magnesium hydroxide), alum precipitation (alum sulfate),
and flocculation (polymer).
The Town of Clayton owns and operates a 2.5 mgd water reclamation facility. The
facility is named; Little Creek Water Reclamation Facility and operates under NPDES
Permit # NC0025453. The facility also delivers reclaim water to the Pine Hollow Golf
under Permit # WQ0022224. The facility is also covered under Stormwater Permit
#NCG110000.
Sludge Management/Maintenance Plan
Little Creek Water Reclamation
Town of Clayton, NC
NPDES Permit # NC0025453
The Town of Clayton owns and operates a municipal wastewater collection and treatment
system, reclaim water, pretreatment program, operates a certified laboratory and
maintains a land application program. Wastewater processed by the treatment facility
originates from domestic and industrial sources. The approximate ratios of these sources
are seventy percent domestic and thirty percent industrial. The Town also has inter-local
agreements with Johnston County Utilities and the City of Raleigh to treat wastewater
from the area. This sludge management plan, as required by the NC Division of Water
Quality, outlines plant processes and management procedures to ensure biosolids disposal
meets both state and federal requirements.

The land application operator in responsible charge is responsible for ensuring that the
sampling and maintenance functions are carried out as outlined in the land application
permit.
The Town is also included permitted at the Johnston County Landfill for dewatered solids
and also maintains an agreement with Johnston County Utilities to dewater thickened
biosolids at the landfill site. The Town may also use McGill Environmental for
composting at its Roseboro or New Hill composting site.
The Town maintains a Residuals Land Application Permit # WQ 0023178. The permit
allows up to 400 dry tons per year of Class B on local farm land. Additional capacity is
available through the use of dewatered solids disposal and off site dewatering.
The following sampling protocols shall be followed. All samples will be collected in
clean and/or sterilized containers provided by the contract laboratory. Chain of custody
information is required for each sample collected (see attachment one). Sampling
equipment shall be cleaned prior to and after sample collection. Sampling equipment
used to collect fecal coliforms shall be sterilized prior to sample collection; all others will
be cleaned with laboratory grade detergent and rinsed with deionized water.

Nutrient, metals, and TCLP analysis contained in the land application and composting
permits will be collected from the sludge holding tank via a clean dipper using a four
sample composite method. The aliquots shall be collected from the walkway at two hour
intervals. The aliquots should be ~ 800 milliliters and placed in a gallon jug in the
laboratory refrigerator. After the fourth sample is added the sample should be well mixed
and transferred into the proper sample containers. A chart is provided on specific sample
requirements. Temperature and pH are grab samples and the pH shall be temperature
corrected.
Plant personnel will document and use the following chart for the temperature correction
for all pH readings.
Fecal coliforms will be collected from the sludge holding tank form the walkway using a
sterilized stainless steel dipper. This walkway is the only safe means to sample this tank.
The seven samples will be collected prior to disposal. Plant staff should request a five-
day turn-around on all samples collected and be aware of the short holding times of 6
hours. In order to meet Class B requirements, the geometric mean must be less than 2
million (MPN/gram TS, or CFU/gram TS). If the counts exceed the regulatory limits the
biosolids may not be land applied until the limits are met.
)
Vector Attraction Reduction:
Pathogen reduction:
Spill control and prevention:
Alternatively a specific oxygen uptake may be performed if the solids concentration is
less than two percent and enough digestion time has been provided, a spreadsheet
provided by the land application unit shall be used for the calculations, a minimum of
seven samples must be taken.
The facility has a spill control plan as required by the facility’s storm water permit. The
sludge loading area has a contoured drainage area that empties into an in plant recycle
system.
Vector attraction reduction will consist of alkali addition directly into either sludge
holding tank. Prior to land application a contractor will be used to supply calcium
carbonate at a level to achieve a ph of > 12 units for two hours and maintain a pH of >
11.5 for an additional 22 hours. There will be no additional material added to the tank
until the land application is complete. A log sheet will be maintained on-site and will
contain the following information: date, times, location, purpose, amount of material
added, initial pH, pH after addition, pH two hours after addition, pH twenty two hours
after addition, names of persons involved, completion date and volume of biosolids land
applied. If the required parameters are not met the process must be successfully
completed prior to land applying the sludge. Note: It is a good practice to perform ajar
test to the contents of the tank prior to treatment, in order to determine the required
amount of alkali to add.

minimum of seven samples will be collected per quarter based upon permit requirements.
Sampling is not required when no events occur during the quarter.
The Town’s hauling contractor is required to have a spill control/ prevention plan.
Inspections:
The land application ORC is required to ensure that the permit conditions are being met
by plant personnel and the sludge application contractor. During each application event
the ORC or backup ORC will visit the sites in use.
Land application rates are based upon Realistic Yield Expectations based upon
information acquired from the North Carolina Department of Agriculture and Consumer
Services. The rates are used by the Town’s contracted soil scientist who prepares
quarterly application summaries and the annual report.
Should the sodium adsorption rate (SAR) of ten (10) or higher be encountered, the Town
will utilize the services of a registered soil scientist to make recommendations to
maintain soil quality.
This is a working document; it must be reviewed periodically for completeness and
efficiency and does not replace the requirements in the various government standards and
permits.

On December 7. 2010, Mack Wiggins of the North Carolina Division of Water Quality, Surface Water
Protection Section, Raleigh Regional Office, conducted a compliance evaluation inspection of the
Town of Clayton Little Creek Water Reclamation Facility, Durham Street Extention, Clayton, NC.
The assistance and cooperation of Mr. James Warren, ORC was very helpful and appreciated during
the inspection process.

9.Effluent is pumped in excess of 1 mile to the Neuse River. The discharge pipe was submerged at
the time of the inspection. The submerged end of pipe appeared to be clear with no visible foam
and debris surfacing.
Two sludge stabilization tanks are utilized. Each tank has a capacity of 400.000 gallons. Sludge
digester prior to sludge stabilization was not being utilized at the time of the inspection.
Stabilization tanks were receiving wasted sludge from the clarifiers at the time of the inspection.
Decant from the sludge stabilization tanks is returned to the sludge thickening building and to the
anaerobic selector tank. The operator explained that once per month Atlantic Dewatering Service
takes the sludge to several farms in Johnston County.
The stand-by power consist of two in-place generators and one portable. Generator No. 1 supplies
power to the main building, influent pump station and aerobic digester. Generator No. 2 supplies
power for the rest of the site. All generators are checked and ran for two hours per week under
load. A local vendor supplies the fuel and keeps the tanks full.
Effluent from the clarifiers goes to tertiary filters consisting of two beds. Each bed has 18 inches of
filter media. Each filter utilizes a traveling bridge which backwashes the filters two hours per day.
The filters were free of growth and clogging at the time of the inspection. Backwash from the filters
is return to the distribution box for the No. 1. and No. 2 oxidation ditch.
The influent pump station has three submersible pumps and one 40 horsepower pump. The visual
and audible alarms were tested and both functioned. Back-up floats are in place and are tested by
operators weekly. The wet well was clear with very little grease and debris at the time of the
inspection.
Wastewater flows from the pump station to Biological Nutrient Removal achieved by a three stage
bardenfo process. The process consist of an anaerobic selector tank which discharges to a
distribution box to divide the flow to two oxidation ditches (No. 1 & No. 2) each with a first stage
anoxic tank. Aerators for each oxidation ditch is operated on variable speeds based on the DO
levels. The DO levels were low during the inspection (0.74 in ditch No. 1 and .20 in ditch No. 2).
However, inner ditch near the aerators had a DO of 1.45 in Oxidation ditch No. 1 and 1.20 in
Oxidation ditch No. 2. The Biological Nutrient Removal process seem to be de-nitrifying and/or
functioning properly during the time of the inspection.
Effluent from the oxidation ditches flows to the clarifier distribution box which distributes the flow
to three secondary clarifiers (No. 1, 2 and 3). Only clarifier No. 2 and No. 3 were being utilized at
the time of the inspection. The operator explained that Clarifier No. 1 is used when the facility has
slug flows. Weirs seem to be level in both clarifiers. Both were free of blockage and short
circuiting. Both clarifiers had no floating scum and sludge. The clarifiers have a 14 foot sidewall
dept. Clarifier No. 2 had a sludge blanket of 2 Vi foot. Clarifier No. 3 had a sludge blanket of less
than 1 foot. Aerobic digester was not in use at the time of the inspection to accept wasted sludge
and scum. With no scum present, activated sludge is returned back to the anaerobic selector tank
and sludge was wasted to the sludge stabilization tanks. Both clarifiers were functioning properly
at the time of the inspection.

6. The facility utilizes a two bank Ultraviolet disinfection system. Chlorine and dechlorination is
available (Note, the Town of Clayton has not needed to use the chlorine & dechlorination system in
8 years). The facility only has to run one bank at a time. Both banks are used only during high
flows. The facility keeps spare bulbs on site. The effluent at this component was clear and free of
solids.
