3. The 2.5 MGD water reclamation facility consists of the following units: influent head works with a
biofilter odor control system that includes a Fiberglass Reinforced Plastic (FRP) cover;
mechanical and automatic bar screens; 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, two banks, with back-up
chlorination / dechlorination; effluent pump station; one 90,000 gallon aerated digester/sludge
stabilization tank; two - 360,000 gallon aerated 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.
1. The reissued NC0025453 permit became effective April 01, 2010 and will expire March 31,
2013. Permit renewal is required within 6 months permit expiration date.
On December 15, 2011, Mitch Hayes of the Raleigh Regional Office conducted a compliance
evaluation inspection of the subject facility. The assistance of James Warren, grade WW-4 Operator in
Responsible Charge (ORC), and Leigh Honeycutt was gratefully appreciated. Please find the attached
Basin Wide Information Management System (BIMS) inspection checklist summarizing each inspection.
Below is a list of recommendations and findings developed from the inspection:
2. The Town of Clayton has contracted with Central Johnston County Regional WWTF to send and
treat 900,000 Gallons per Day (GPD), with a minimum of 150,000 GPD, to the Central Johnston
County Regional WWTF. The Town of Clayton also has an agreement with the City of Raleigh
to send and treat 1 MGD to the Neuse River Wastewater Treatment Plant however;
infrastructure has yet to be constructed.

4. At the time of inspection, automatic and manual bar screens and vortex grit removal system
were functioning normally. The biofilter odor control system appear to be operating normally
based on very little odor at the influent head works. A diffuser pipe was being repaired in the
number 2 aerated sludge holding tank. The number 1 aerated sludge holding tank was
approximately 80% full. Aerators in sludge holding tank number 1 were operational. Sludge was
not being thickened in the rotary drum thickener at the time of inspection. The thickener is
operated twice a week. Influent in the two oxidation basins was medium brown in color with very
little foam. Covers have been placed over the anaerobic selector to prevent odor. The #2
secondary clarifier was not in use due to low inflow. There was no foam noted in secondary
clarifier #2 or #3. Sludge blanket in the #2 clarifier was 1 foot and 1 72 feet in clarifier #3. Both
clarifiers have 14 foot sidewall depths. Effluent in the wet well at the tertiary filters appeared
clear with no foam. The sludge drying beds had no sludge in them.
Biosolids are land applied under the Town of Clayton Land Application Permit WQ0023178. The
permit will expire September 30, 2015. Granville Farms is designated the back-up hauler to land
apply biosolids under the GFI Residuals Land Application Program under permit WQ0000838. A
Certificate of Approval was issued December 17, 2010 to Johnston County Residuals
Dewatering Facility to accept up to 150 dry tons of residuals per year from Little Creek Water
Reclamation Facility.
6. In-plant non-potable water using treated wastewater effluent is utilized throughout the plant is
covered under NPDES Permit 25453. The reuse generation distribution line and pump station
with force main to the Pine Hollow Golf Course is covered under permit WQ0024223 that will
expire September 30, 2015. Reuse, reclaim water, and land application permits are currently
managed by the Aquifer Protection Section.
7. The laboratory was checked in a cursory manner. All instrument calibration logs are being
maintained in a log book. Fecal coliform bath temperature was 44.5 degrees C and the
laboratory refrigerator was 3 degrees C. BOD incubator temperature was 20 0 C The influent
and effluent flow meters were calibrated November 15, 2015 by Chadwick Instruments. The
influent sampler temperature was 5 degrees C and the effluent sampler temperature was 3 %
oeyrees o.
10. Inspection of the stormwater outfalls and plant site was conducted at the same time as the CEI
for the Water Reclamation Facility. Permit NCG110080 was reissued and became effective on
June 01, 2008 and will expire on May 31, 2013.
11. There are six stormwater outfalls listed for the facility:
a. Stormwater Outfall 001 consists of drainage from the return sludge pump station; on-site
generator area, chlorine contact chamber and effluent pump station. Flow is conveyed
by concrete pipe and discharges to a small drainage ditch behind the on-site generator
and tertiary filter structure. There was no discharge and no water in the drainage ditch at
the time of inspection.

discharge into a small ditch. There was no discharge at the time of inspection. Water in
the ditch appeared clear.
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.
Stormwater Outfall 003 receives flow from the on-site generator and fuel tank behind the
operations building, and area near the aerobic digester. The combined flows discharge
to low lying area across from the right side of the operations building. Water in the low
lying area appeared clear.
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. There was no water
in the ditch.
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 a
sediment trap at Outfall 006. Any water in the sediment trap flows through crushed stone
at the end of the discharge point and into a wooded area. There was no discharge at the
time of inspection.
12. Qualitative monitoring for all outfalls was last conducted on April 27, 2011. There is no vehicle
maintenance done on site. There have been no spills for the 2010-2011 year. The stormwater
pollution prevention control plan was amended in 2009. Annual employee training on spill
prevention and response occurred on December 06, 2011.
I would like to thank James Warren and Leigh Honeycutt time and assistance with this inspection. If

Staff is evaluating methods to back up the control circuit. This may include the installation of an
uninterruptable power source. A separate low voltage circuit may also be considered. We propose that we will
have the backup circuit implemented within 45 days.
