Dear Mr. Broome:
Dee Freeman
Secretary
Mitch Hayes of the Raleigh Regional Office conducted an inspection of the subject facility on April 28,
2009. The time and assistance of Dan Wall, Operator in Responsible Charge (ORC), William Denton, back-up
ORC, Jennifer Doll and Chad Thompson were greatly appreciated. Below is a list of findings and recommendation
developed from the inspection:
The current permit was reissued and became effective October 01, 2007 and will expire September 30,
2012. The 7.0 MGD Wastewater Treatment Facility consists of the of the following units: influent pump
station; two mechanical bar screens with screenings compactor, Parshall flume with ultrasonic flow
meter; influent pump station with 2 variable speed and 1 constant speed pump; 2 treatment trains with
anoxic and aeration basins; five secondary clarifiers; four RAS pump stations; methanol feed facilities; 5
deep bed de -nitrification filters; filter influent pump station wet well; filter influent pump station; one
clearwell; ultraviolet disinfection facility; cascade aeration structure; one effluent ultrasonic flow meter;
two filter backwash reclaimed water tanks; one reclaimed water contact/storage tank; one reclaimed
water pump station; one aerobic digester/solids storage tank; one liquid waste solids transfer pump
station; back-up chlorination basins; three on site generators for back up power.
Construction to the waste treatment facility to increase the permitted capacity and flow design to 9.5
MGD is approximately 60% complete with a completion date scheduled April 25, 2010. At the time of
inspection, the new influent splitter box had been formed, aeration basin number 7 was approximately
80% complete, clarifier number 6 Had been poured, reinforcing steel had been erected for the
denitrification filter walls, wiring for the UV disinfection had been relocated to the UV lamps, the lime silo
has been relocated to dewatering facility, and the 1.5 MG aerated sludge holding tank located at the
dewatering facility was in service.
At the time of inspection, one aeration basin was not in use due to regularly scheduled cleaning,
clarifier number 5 was not in use due to low inflow, and the influent anoxic basin was not being used.
The influent flow sampler was out of service due to on -site contractor cutting electrical service. Influent
samples were being collected hourly and composited. Influent in the aeration was a light brown with
minimal foaming. Dissolved oxygen is kept around 5.0 mg/i to compensate for the higher outside
temperature. Weirs in the secondary clarifiers all appeared level. There were some areas were the v-
notches on the weir plate had detached from the effluent launder causing some short-circuiting. Most of
the weir plates in secondary 1,2,3 and 4 were rusted and could become a problem if attention is not
given in the near future. Otherwise, the effluent flowing off the weirs appeared clear. Sludge blanket in
secondary clarifier number 1 was 4 feet with a sidewall depth of 12 feet. There was no algae build up in
the effluent trough and weirs. Solids in the aerobic digester were being prepared to be sent to the

dewatering facility at the landfill. Supernatant was being pumped back to the head of the plant. The
denitrification filters were being backwashed at the time of inspection. Effluent appeared clear in the
clear well with little foaming. Effluent entering the Neuse River appeared clear with no foam or odor.
4. The laboratory was checked in a cursory manner. All instrument calibration logs are being maintained in
logbooks. An operator's logbook was available and being maintained. Fecal coliform bath temperature
was 44.5 degrees C, the drying oven temperature was 105 degrees C. BOD incubator was 20.0 C, and
the main refrigerator was 1 degree C. All meters including influent and effluent flow meters were last
calibrated March 26, 2009. Effluent flow sampler temperature was 4 degrees C.
5. Discharge Monitoring Reports for the period July 2008 to February 2009 were reviewed for compliance
with permit limits and monitoring requirements. One frequency violation was noted for 09/2008 for the
parameter Zinc. It was determined that the value for Zinc was transposed in another column. No action
is necessary.
6. Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the Discharge Monitoring Report (DMR) for the month of February 2009. No
discrepancies were noted.
Stormwater Permit NCG110077
7. Permit NCG110077 was issued and became effective on June 01, 2008 and will expire on May 31,
2013. A review of the permit requirements was conducted after the CEi for NC003017. A copy of the
permit was on hand and contained all permit requirements with the exception that the general location
map list the receiving water (UT to Neuse River) as impaired or not and what the parameter(s) of
concern are.
8. Qualitative monitoring is done according to the permit schedule. The last two monitoring sets were
completed March 20, 2009 and August 7, 2008. A qualitative monitoring report supplement has been
developed as guidance for rating stormwater discharge. This document can be found on the forms and
documents page http://h2o.enr.state.nc-us./su/Forms_ Documents.htm Look under the Miscellaneous
Forms section and click on Qualitative Monitoring Form Guidance Supplement.
9. One distinct stormwater outfall is listed on the 2003 stormwater map of the facility. Stormwater drains at
the screenings area and at the sludge press area are routed back to the head of the plant. A Secondary
containment wall is provided for the methanol and sodium hypochlorite tanks. The alum and
magnesium sulfite silos have secondary containment and are empty and have never been used. The
methanol tank is double walled and sensors monitor the tank for any leaks All other stormwater is
routed to one common discharge pipe and discharges next to the wastewater treatment facility's
effluent discharge pipe to an unlined channel that drains to the Neuse River. There was no stormwater
discharge at the time of inspection.
10. Stormwater Pollution Prevention Plan was available during inspection. Staff training on spill response
and prevention was completed on November 20, 2008. Training is completed every six months.
i would like to thank the staff of Central Johnston County Regional WWTF for their time and assistance with
this inspection. The staff should be commended for maintaining the wastewater treatment facility at top
performance. if you have any questions about this fetter or the inspection, please contact me at 919.791.4261.

Approximately 30% of the 371 auger piles have been placed with concrete. Approximately 70% of the demolition to
the deep -bed denitrification filter building had been completed. The prestressed concrete tank structure for the 1.5 MG
aerated sludge holding tank has been completed. Concrete has been demoed for the filter press.
4. At the time of inspection, one aeration basin and two secondary clarifiers were not in operation due to low flow and
cleaning. Basins are cleaned every six months to remove grit. Two out of three influent pumps were being operated
due to low flow. One out of two banks of UV was being operated due to low flow. The two banks of UV light cycle
on according to flow. All other units were in operation at the time of inspection. The influent in the aeration basin
appeared tan in color. Dissolved oxygen is kept at 3.8 mgll in the front of the basin and 3.3 in the back of the basin.
All diffusers were operating normally. Sludge judge reading in the 85-foot diameter secondary clarifier was 3 'h with
a sidewall depth of 12 feet. The weirs appeared level with no drafting of solids. There was no indication of algae
growth on the weirs or in the trough. The effluent flowing off the weirs appeared clear. The deep bed de -nitrification
filters are manually backwashed every 48 hours and 24 hours before an anticipated large rain event. Effluent in the
clear well appeared clear. The aerated digester at the county landfill was approximately one-half full. All diffusers
were operational. Belt filter presses were operating normally. Sludge was being collected to be land filled.
The influent pumps were turned off to test SCADA and the audible/visual alarms. The audible and visual alarms
functioned when the influent wet well was allowed to fill to the high water level. SCADA reported a high wet well
and power out. Emergency generators are operated every day for peak shaving and before an approaching storm.
6. The effluent in the cascade aerator and entering the Neuse River appeared clear with no evidence of solids, foam, or
odor.
Solids in the digester/solids storage tank are conveyed via force main to the Johnston County Landfill for dewatering.
The supernatant from the sludge dewatering at the county landfill is conveyed back to the wastewater treatment head
works via force main for processing. The dewatered solids are landfilled in accordance with permit WQ0020632.
Reclaimed water is distributed under permit WQ0019632. Reuse water is pumped to the Johnston County landfill for
irrigation at the Johnston County Landfill under Permit WQ0019631. Reclaimed, reuse water permits and other non -
discharge permits are regulated by the Aquifer Protection Section (APS). All correspondence pertaining to these
permits should be directed to the APS.
9. The laboratory was checked in a cursory manner. All instrument calibration logs are being maintained. All pH buffers
were within expiration date. An operator's logbook was available and being maintained. The influent and effluent
flow meters were calibrated February 21, 2008. All meters and instruments are calibrated by Milco Calibrations, LLC.
Fecal coliform bath temperature was 44.5 degrees C, drying oven temperature was 103 degrees C, and the BOD
incubator temperatures were 20.0 and 19.0 degrees C.
10. The wastewater treatment plant staff analyzes pH, temperature, dissolved oxygen, alkalinity, BOD, total phosphorus,
total suspended solids, settleable solids, ammonia, and conductivity. Environment I and Mentech performs all other
analyses.
11. Discharge Monitoring Reports for the period February 2007 to June 2008 were reviewed for compliance with permit
limits and monitoring requirements. There were no violations for the period.
12. Commercial lab results, chain of custody records, and bench sheets were compared with data submitted on the
Discharge Monitoring Report (DMR) for the month of April 2008. No discrepancies were noted.
Stormwater Permit NCG 110077
13. Permit NCG110077 was issued and became effective on June 01, 2008 and will expire on May 31, 2013. The reissued
permit contains the following changes: The site plan must include a general location map (or alternatively the site
map) that identify whether each receiving water is impaired (on the state's 303(d) list of impaired waters) or is located
in a watershed for which a TMDL has been established, and what the parameter(s) of concern are. A list of North
Carolina's 303(d) list can be found at the web site http://h2o.enr.state.ne.us/tmdl/General 303d.htm#Downloads

http://h2o.enr.state.nc.usitmdI/TMDL_list.htm#Final_TMDLs The definition for a rain event has been modified. A
schedule for qualitative monitoring is now implemented. Schedule for the facility site inspection has been changed to
once during January to June and once during July to December with at least sixty days separating inspection dates
unless performed more frequently. There are no other significant changes made to the permit. A review of the permit
requirements was conducted after the CEI for NC003017. A copy of the permit was on hand and contained all permit
requirements with the exception of the new requirements noted above.
14. Qualitative monitoring and first sampling analyses for the stormwater permit was conducted on May 17, 2007 and
May 09, 2008. There is no vehicle maintenance done on site.
15. One distinct stormwater outfall is listed on the 2003 stormwater map of the facility. Stormwater drains at the
screenings area and at the sludge press area are routed back to the head of the plant. A Secondary containment wall is
provided for the methanol and sodium hypochlorite tanks. The alum and magnesium sulfite silos have secondary
containment and are empty and have never been used. The methanol tank is double walled and sensors monitor the
tank for any leaks All other stormwater is routed to one common discharge pipe and discharges next to the wastewater
treatment facility's effluent discharge pipe to an unlined channel that drains to the Neuse River. There was no
stormwater discharge at the time of inspection.
16. Stormwater Pollution Prevention Plan was available during inspection. Staff training on spill response and prevention
was completed on May 18, 2007 and May 08, 2008.
I would like to thank again Dan Wall and the staff of the treatment facility with their time and assistance with this

Johnston County
Dear Mr. Broome:
Alan W. Klimek, P.E., Director
Division Of Water Quality
On March 06, 2007, Mitch Hayes of the Raleigh Regional Office conducted an inspection of the
subject facility. The inspection was conducted in conjunction with an EPA compliance evaluation
inspection conducted by Liza Montavola and a maintenance laboratory inspection conducted by David
Livingston with the N. C. Laboratory Certification Section. The assistance of Dan Wall, Operator in
Responsible Charge (ORC) and the staff of the wastewater treatment facility were appreciated. Below is a
list of findings and recommendation developed from the inspection.
1. The current permit was reissued and became effective November 1, 2002 and will expire August
31, 2007. The NPDES Unit received the permit renewal package November 14, 2006 and is under
review. Please continue to operate under the last issued NPDES permit until the permit is renewed.
2. The 7.0 MGD Wastewater Treatment Facility consists of the of the following: influent pump
station; two mechanical bar screens with screenings compactor, Parshall flume with ultrasonic
flow meter; influent pump station with 2 variable speed and 1 constant speed pump; 2 treatment
trains with anoxic and aeration basins; five secondary clarifiers; four RAS pump stations; methanol
feed facilities; 5 deep bed de -nitrification filters; filter influent pump station wet well; filter
influent pump station; one clearwell; ultraviolet disinfection facility; cascade aeration structure;
one effluent ultrasonic flow meter; two filter backwash -reclaimed water tanks; one reclaimed water
contact/storage tank; one reclaimed water pump station; one aerobic digester/solids storage tank;
one liquid waste solids transfer pump station; back-up chlorination basins; three on site generators
for back tip power.
3. One of the aeration basins was not in operation due to cleaning. Basins are cleaned every six
months to remove grit. The two banks of UV light cycle on according to flow. At the time of
inspection, one bank of UV was at 6%. All other units were in operation at the time of inspection.
The influent in the aeration basin appeared light brown in color. All diffusers were operating
normally, Sludge judge reading in Clarifier 5 was 5 %2 with a sidewall depth of 15 feet. Sludge

judge reading in clarifier 4 was 1% foot, clarifier 3 was 3 feet, clarifier 2 was 4 feet, and clarifier 1
was 3 % feet. Sidewall depth in clarifiers 1, 2, 3, and 4 is 12 feet. Flow over the weirs appeared
clear with no drafting of solids noted. The pumps in the RAS pump station are cleaned out every
two weeks. The deep bed de -nitrification filters are manually backwashed every 60 hours.
4. Most of the pumps, mode of operation of aeration basins, methanol feed facility, backwashing of
sandfilters, can be regulated from a computer console. Most units on site are connected to
SCADA. The influent pumps were turned off to test SCADA and the audible/visual alarms. The
audible and visual alarms functioned when the influent wet well was allowed to fill to the high
water level. SCADA reported a high wet well and power out. Emergency generators are operated
every day for peak shaving.
5. The effluent in the cascade aerator and entering the Neuse River appeared clear with no evidence
of solids, foam, or odor.
6. Solids in the digester/solids storage tank are conveyed via force main to the Johnston County
Landfill for dewatering. The supernatant from the sludge dewatering at the county landfill is
conveyed back to the wastewater treatment head works via force main for processing. The
dewatered solids are landfilled in accordance with permit WQ0020632.
7. Reclaimed water is distributed under permit WQ0019632. Reuse water is pumped to the Johnston
County landfill for irrigation at the Johnston County Landfill under permit WQ0019631.
Reclaimed, reuse water permits and other non -discharge permits are regulated by the Aquifer
Protection Section (APS). All correspondence pertaining to these permits should be directed to the
APS.
8. The laboratory was checked in a cursory manner. All instrument calibration logs are being
maintained. All pH buffers were within expiration date. An operator's logbook was available and
being maintained. The influent and effluent flow meters were calibrated February 26, 2007. Fecal
coliform bath temperature was 44.5 degrees C, drying oven temperature was 105 degrees C, and
the BOD incubator temperature was 20.0 degrees C.
9. The wastewater treatment plant staff analyzes pH, temperature, dissolved oxygen, alkalinity, BOD,
total phosphorus, total suspended solids, settleable solids, ammonia, and conductivity.
Environment 1, Meritech and Tritest performs all other analyses.
10. Discharge Monitoring Reports for the period August 2006 to January 2007 were reviewed for
compliance with permit limits and monitoring requirements. Daily maximum permit limit violation
for mercury reported 08/08/2006. This violation is believed to be caused by laboratory and or
sampling technique error. There were no other violations for the period.
11. Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the Discharge Monitoring Report (DMR) for the month of December 2006. No
discrepancies were noted.
Stormwater Permit NCGI 10077
12, Permit NCG110077 was issued and became effective on January 01, 2004 and will expire on April
30, 2008. Please be sure to apply for a permit renewal by October 31, 2007 to avoid civil penalty.
A review of the permit requirements was conducted after the CEI for NC003017. A copy of the
permit was on hand and contained all permit requirements.

13. Qualitative monitoring and first sampling analyses for the stormwater permit was conducted on
04/17/2006 and 10/17/2006. There is no vehicle maintenance done on site.
14. One distinct stonnwater outfall is listed on the 2003' stormwater map of the facility. Stormwater
drains at the screenings area and at the sludge press area are routed back to the head of the plant. A
Secondary containment wall is provided for the methanol and sodium hypochlorite tanks. The
methanol tank is double walled and sensors monitor the tank for any leaks All other stormwater is
routed to one common discharge pipe and discharges next to the wastewater treatment facility's

Notice of Violation NOV-2005-PC-0191
Stormwater Permit NCG 110077
Johnston County
On May 12, 2005, Mitch Hayes of the Raleigh Regional Office conducted an inspection of the subject
facility. The assistance of Dan Wall, Operator in Responsible Charge (ORC), was appreciated. Below is a
list of findings and recommendation developed from the inspection.
1. The current permit was reissued and became effective November 1, 2002 and will expire August
31, 2007.
2. The Class 4 Wastewater Treatment Facility has undergone major upgrades to the treatment process
and after completion will provide tertiary treatment for a permitted flow capacity of 7.0 MGD. Mr.
Dan Wall stated in a phone conversation on August 3, 2005 that the Engineer's Certificates of
completion were sent in on August 1, 2005. Please note that expansion at or above 5 MGD will
require 24-hour operation. New effluent permit limits for N113-N will also take effect at 7.0 MGD.
3. The 7.0 MGD Wastewater Treatment Facility consists of the of the following: influent pump
station; two bar screens with one manual bypass screen, screenings compactor, two Parshall
flumes; influent ultrasonic flow meter; five aeration basins providing 2-stage biological nitrogen
removal with one basin operating as a anoxic zone; five secondary clarifiers; four RAS pump
stations; methanol feed facilities; filter influent pump station wet well; filter influent pump station;
five deep bed denitrification filters; two filter backwash reclaimed water tanks; one clearwell;
ultraviolet disinfection facility; cascade aeration structure; one effluent ultrasonic flow meter; one
reclaimed water contact/storage tank; one reclaimed water pump station; two solids storage tanks,
one aerobic digester, one liquid waste solids transfer pump station; three on site generators for

back up power. This office request that a narrative description of installed wastewater treatment
components at the facility that includes sizes and capacities for each component and a schematic of
the wastewater flow that identifies specific treatment components be sent to this office. Dan Wall
stated that the plant would begin construction next year to expand the plant to 9.5 MGD.
4. One on -site generator was out of service and being repaired. The influent pump station is
connected to the SCADA system. The high water alarm sounded when pumps I and 2 were turned
off. SCADA reported a power out and high flow. The three on site generators are exercised every
day under load for peak shaving. The grit chamber, EQ basin, sludge press, and two older clarifiers
are not being used. The effluent in the cascade aerator and entering the Neuse River was clear with
no evidence of solids, foam, or odor.
5. Liquid waste solids are conveyed via new force main to the Johnston County Landfill for
dewatering. Solids are dewatered using two 1.5-meter belt filter presses and are stared in one of
two solids storage basins until landfilled in accordance with permit WQ0020632.
6. Reclaimed water is distributed under permit WQ0019632. Reuse water is pumped to the Johnston
County landfill for irrigation at the Johnston County Landfill under permit WQ0019631.
Reclaimed, reuse water permits and other non -discharge permits are regulated by the Aquifer
Protection Section (APS). All correspondence pertaining to these permits should be directed to the
APS.
7. The laboratory was checked in a cursory manner. All instrument calibration logs are being
maintained. All pH buffers were within expiration date. An operator's logbook was available and
being maintained.
8. The wastewater treatment plant staff analyzes pH, temperature, dissolved oxygen, alkalinity, BOD,
total phosphorus, total suspended solids, settleable solids, ammonia, and conductivity.
Environment land Tritest analyses all other parameters.
9. Discharge Monitoring Reports for the period May 2004 to May 2005 were reviewed for
compliance with permit limits and monitoring requirements. One weekly limit violation for total
mercury was noted on May 31, 2005. This will be addressed in future correspondence. There were
no other limit or monitoring violations for the period.
10. Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the Discharge Monitoring Report (DMR) for the month of February 2005. No
discrepancies were noted.
Stormwater Permit NCG 110077
11. Permit NCG110077 was issued and became effective on January 01, 2004 and will expire on April
30, 2008. A review of the permit requirements was conducted after the CEI for NC003017. The
stormwater permit was not available for the inspection. One of the major components of the
stormwater permit is that a Stormwater Pollution Prevention Plan (SWPPP) be developed. A
SWPPP has yet to be developed. Minimum requirements for the SWPPP can be found in the
permit in Part II Section A, items 1 through 9. Qualitative monitoring is required for each
stormwater outfall twice a year, once in the spring (April -- June), and once in the fall (September —
November). Analytical monitoring is required for facilities that have any vehicle maintenance
activity occurring on site which uses more than 55 gallons of new motor oil per month when
averaged over the calendar year. Requirements for the monitoring are specified in Table 2, Section
C of the stormwater permit.
