NPDES Permit No. NCO020389
Stormwater Permit No. NCG110062
Johnston County
Dear Mr. Morris:
Dee Freeman
Secretary
On July 13, 2011 Mitch Hayes of the Raleigh Regional Office conducted a compliance evaluation
inspection of the subject facility. The assistance of Steve Proctor, David Paul Allen and you with this
inspection was gratefully appreciated. Please find the attached Basin Wide Information Management
System (B1MS) inspection checklist summarizing each inspection. Below is a list of recommendations
and findings developed from the inspection:
Permit NCO020389 was reissued 03,15,2010 and became effective 04.01,2010. The permit will
expire 04.30.2013. Permit renewal is required within180 days prior to expiration date.
2. The Basinwide Information Management System (BIMS) currently lists Martin Morris as grade
WW-4 Operator in Responsible Charge (ORC) and Steve Proctor grade WW-4 back-up ORC
(bORC). You stated that David Paul Allen will become the ORC when he completes the
requirements for a grade WW-4 operator. If you have any questions concerning ORC or b-ORC
designation, please contact Steve Reid in the Technical Assistance Certification Unit at
919.733.0026 extension 314.
3. The 1.9 MGD wastewater treatment facility consists of the following units: 2 concrete lined
equalization basins, arc bar (mechanical bar screen), grit chamber, 2 manual bar screens,
influent Parshall flume, influent ultrasonic flow meter, 3 screw pumps, 3 oxidation ditches (1
used for nutrient removal), 5 secondary clarifiers (2 @ 10' depth, 2 @ 11' depth, 1 @ 14' depth),
5 deep bed tertiary filters, dual chlorine contact chamber with gaseous chlorine, post aeration
tank, effluent flow meter with ultrasonic sensor using a 2-feet rectangular weir with end
contractions, sodium metabisuifite dechlorination, an effluent reuse system providing irrigation
to three athletic fields at the South Johnston County High School, an effluent reclaim water
spray irrigation system that can apply up to 1.97 MG per year on the 1.65 acres of land beside
the oxidation ditch number 3, and a 3 MG concrete lined aerated sludge basin with 3 floating
aerators.

4. At &f 'time-of•inspectiorr;-one out of three screw pumps were being operated due to low inflow.
The two screw pumps not being operated did function when manually turned on. All brush rotors
in the three oxidation ditches were being operated on a time delay and at variable speed for
biological nitrogen and phosphorus removal. The number 4 secondary clarifier was not in
service due to low inflow. There was no effluent flowing over the weirs due to low flow in
secondary clarifier numbers 1, 2 and 3. Effluent flowing off the weirs in secondary clarifier 5,
appeared clear with no pin floc or solids. Very little algae were noted in all the secondary
clarifiers. Sludge blanket in the # 2 clarifier (10 foot sidewall depth) was 1 foot. Sludge blanket in
the #5 clarifier (14 foot sidewall depth) was 1 '/2 feet. The number 4 tertiary filter was out of
service due to a broken hydrocone base. This was noted in last year's inspection. You stated
that the hydrocone base will have to be handmade. All other tertiary filters were in service.
Effluent in the chlorine contact tank, dechlorination post aeration tank, and at the outfall
appeared clear with no solids. There was no discharge from the new effluent discharge outfall
due to low flow: Freeboard level in the EQ basin was 1.90 feet.
5. The Town of Benson has a contract with McGill Environmental System of NC, Inc. to dispose of
25 dry tons sludge per year under McGill's 503 permit WQ0006816 at their Delway, NC facility.
1.4 MG of sludge was removed from the 3 MG aerated sludge basin in 2010. 1.5 MG of sludge
is scheduled to be removed this year.
6. The laboratory was checked in a cursory manner. All instrument calibration logs are being
maintained on computer. An operator's logbook was available and being maintained. Fecal
coliform bath temperature was 44.6 degrees C, the drying oven was 104 degrees C, and the
laboratory refrigerator was 3 degrees C. All meters were calibrated 12.21.2010 by Johnston
Controls Inc. Influent sampler temperature was 13.5 degrees C and the effluent sampler
temperature was 4.8 degrees C. I was informed by David Allen on July 15, 2011 that the influent
refrigerator had been repaired and is cooling properly.
7. Discharge Monitoring Reports (DMR's) for the period September 2009 to April 2011 were
reviewed for compliance with permit limits and monitoring requirements. Two violations were
listed for the review period: exceeding weekly average BOD on October 30, 2010 and failing to
monitor for mercury on April 30, 2011. You stated that data for mercury was inadvertently left off
the DMR and that an amended DMR was submitted. The October 30, 2010 violation has been
addressed.
Stormwater Permit NCG110062
8. Inspection of the stormwater outfalls and plant site was conducted at the same time as the CEi
for the wastewater treatment plant. Permit NCG110062 was reissued and became effective on
June 01, 2008 and will expire on May 31, 2013. Permit renewal is required within180 days prior
to expiration date.
9. There are two stormwater outfalls listed for the facility:
a. Outfall 001 consists of drainage from the office/laboratory building and surrounding
roadway drainage that is conveyed by concrete pipe to a drainage structure near the
secondary clarifiers. This combined flow drains to a swampy area near the influent flow
structure. There was no discharge at the time of inspection.
b. Stormwater from roof drainage, the building housing the reuse water tank and sodium
metabisulfate tank, and the shelter housing the chlorine gas tank is conveyed to the EQ
basin via underground piping. Stormwater use to discharge onto the ground near the
fence behind the building housing the reuse water tank and sodium metabisulfite tank,
former Stormwater Discharge Outfall (SDO) #2.
Outfall 003 consists of all other stormwater drains that flow to one common stormwater
pipe that discharges to Hannah Creek. The outfall is next to the effluent discharge pipe.

Page 3
It appeared that there was no discharge at the time of inspection though the pipe was
submerged into the water.
10. Qualitative monitoring was last documented for SDO's 1 and 3 August 2010. There was no
documentation of qualitative monitoring for SDO's 1 and 3 for Period 2, Year 3. Employee
training on proper spill response and clean-up procedures and preventative maintenance
activities is not being documented. Annual certification that all stormwater outfalls have been
evaluated for the presence of non-stormwater discharges is not being completed. The last
update to the site map was in 2003. The map does not include the new reclaimed water spray
field adjacent to oxidation ditch # 3 and still lists 3 SDO's. Please note that failure to abide by
the conditions and limitations contained in the permit may subject the Permittee to a civil penalty
up to $25,000 per day per violation.
Please respond in writing to item 10 within 30 days receipt of this letter. I would like thank
everyone for their assistance with this inspection. If you have any questions about this letter please
contact me at 919.791.4261 or by email at [e-mail] .
Sincerely,

Coleen H. Sullins, Director
Division of Water Quality
On November 05, 2008 Mitch Hayes of the Raleigh Regional Office conducted a compliance
evaluation inspection of the subject facility. The assistance of Martin Morris grade WW-4 Operator in
Responsible Charge (ORC) and Steve Proctor grade W W-4 back-up ORC 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:
1. The subject permit expired April 30, 2008 and is currently under review. Please continue to
operate under the last issued permit until a new permit is issued.
2. The 1.9 MGD wastewater treatment facility consists of the following units: 2 concrete lined
equalization basins, arc bar (mechanical bar screen), grit chamber, 2 manual bar screens, influent
Parshall flume, influent ultrasonic flow meter, 3 screw pumps, 3 oxidation ditches (1 used for
nutrient removal), 5 secondary clarifiers (2 @ 10' depth, 2 @ I depth, 1 @ 14' depth), 5 deep
bed tertiary filters, dual chlorine contact chamber with gaseous chlorine, post aeration tank,
effluent flow meter with ultrasonic sensor using a 2-feet rectangular weir with end contractions,
sodium metabisulfite dechlorination, an effluent reuse system providing irrigation to three
athletic fields at the South Johnston County High School, an effluent reclaim water spray
irrigation system that can apply up to 1.97 MG per year on the 1.65 acres of land beside the
oxidation ditch number 3, and a 3 MG concrete lined aerated sludge basin with 3 floating
aerators.
3. At the time of inspection, two out of three screw pumps were being operated due to low flow.
The screw pump that was not being operated did function when the high float was lifted up. The
# 2 oxidation ditch is being operated as a de-ox zone. The #1 and #3 oxidation ditches were in
service. There was very little effluent flowing over the weirs in the secondary clarifiers. All
weirs were free of algae. Sludge depth in the # 5 secondary clarifier was approximately one -

quarter foot with a sidewall depth of l4'.'•Thb—number 3 tertiary filter was out of service due to a
broken hydrocone base. All other tertiary filters were in service. Effluent flowing into the post
aeration tank appeared clear. Effluent discharging into Hannah Creek / swamp appeared clear
with no visible solids or foam. Level in the sludge storage lagoons was down approximately
three feet. Level in the equalization lagoon was down approximately two feet.
4. Upgrade to increase the wastewater treatment plant permitted capacity to 1.97 MGD has been
completed. The following items were constructed during the upgrade:
■ A new 14 feet sidewall depth, 15 feet in diameter secondary clarifier, mixed liquor
effluent collection box and a new flow splitter box downstream of the existing oxidation
ditches.
■ Sidewalls for the influent structure, grit chamber, mechanical bar screen, diversion box,
and existing secondary clarifiers and the oxidation ditches sidewalls have been raised
above the 100-year flood plain.
■ The existing 4-7.5 hp brush rotor drives in oxidation ditches # 1 and #3 were replaced
with 4-15 hp drives. Oxidation ditches # 1 and 93 contain one new 15 hp rotor with new
brushes.
• All three -filter lift pumps have been upgraded and expanded to 30 hp each at 2300 gpm.
■ Two existing screw pumps have been replaced with two new 5 hp 1,750 gpm screw
pumps.
■ A new 30" D.I. parallel effluent outfall line has been installed and is in use. The new
outfall line is 5 feet offset from the existing 21" effluent outfall line.
■ A new yard hydrant and water meter for the reclaim water irrigation system has been
installed and in use. The effluent reclaim water spray irrigation system will apply up to
1.97 MG per year on the 1.65 acres of land beside the oxidation ditch number 3.
5. The Town of Benson land application permit WQ0012514 expired August 31, 2007. Even
thought the permit has expired, the permit is still considered to be available. A request to rescind
the permit should be made to the close out the permit. Please mail your request to Land
Application Unit, 1636 Mail Service Center, Raleigh, NC 27699-1636. According to Martin
Morris, money has been budgeted for the 2008-2009 physical year to remove sludge in the 3 MG
aerated sludge basin. Atlantic Dewatering Inc. will dewater the sludge and take the solids to
McGill Environmental Systems Of N C in New Hill. All permits will be obtained from Atlantic
Dewatering Inc. The aerated sludge basin was last pump out in 2003 by Atlantic Coast
Contracting, Inc.
6. The laboratory was checked in a cursory manner. All instrument calibration logs are being
maintained on computer. 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,
and laboratory refrigerator was 2.1 degrees C. The influent and effluent flow meters were
calibrated October 10, 2008 by Johnston Inc. Influent sampler temperature was 1 degrees C and
the effluent sampler temperature was 3 degrees C.
7. Discharge Monitoring Reports (DMR's) for the period October 2007 to September 2008 were
reviewed for compliance with permit limits and monitoring requirements. Flow was exceeded for
April 2008. The exceedence was less than 10% of the permit limit; no further action is needed.
There were no other violations for the review period.
8. Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the DMR for the month of September 2008. No discrepancies were noted.

Stormwater Permit NCG 110062
9. Inspection of the stormwater outfalls and plant site was conducted at the same time as the CEI
wastewater treatment plant. Permit NCG110062 was reissued and became effective on June 01,
2008 and will expire on May 31, 2013.
10. Expansion to the wastewater treatment plant has been completed. The site plan that is dated 2003
should be updated to include the upgrades made to the treatment plant.
11. There are three outfalls listed for the facility:
a) Outfall 001 consists of drainage from the office/laboratory building and surrounding
roadway drainage that is conveyed by concrete pipe to a drainage structure near the
secondary clarifiers. This combined flow drains to a swampy area near the influent flow
structure. Water in the swamp area appeared clear.
b) Stormwater from roof drainage, the building housing the reuse water tank and sodium
metabisulfate tank, and the shelter housing the chlorine gas tank is conveyed to the
stabilization lagoon through underground concrete pipe. This flow was thought to have
discharged offsite and is currently designated Outfall 002. This outfall is not necessary
and until a request is made to rescind Outfall 002 from the permit, all monitoring for
Outfall 002 should continue.
c) Outfall 003 consists of all other stormwater drains on the property that flow to Hannah
Creek. The outfall is next to the effluent discharge pipe. It appeared that there was no
discharge at the time of inspection though the pipe is half submerged into the water.
12. Qualitative monitoring for Outfalls 001 and 003 was conducted on February 01, 2008 and
September 26, 2008. There is no vehicle maintenance done on site.
13. There have been two bypasses for the 2007-2008 year. One by-pass occurred on 05/31/2008 that
resulted in 500 gallons released into Hanna Creek. The other by-pass occurred on 08/31/2008
that resulted in 48,000 gallons released into Hanna Creek. Both bypasses were caused by
equipment failure.

contractions, sodium metabisulfite dechlorination, an effluent reuse system providing irrigation
to three athletic fields at the South Johnston County High School, an effluent reclaim water
spray irrigation system that can apply up to 1.97 MG per year on the 1.65 acres of land beside
the oxidation ditch number 3, and a 3 MG concrete lined aerated sludge basin with 3 floating
aerators.
3. At the time of inspection, two out of three screw pumps were being operated. The third screw
pump operates when there is a high inflow and did operate when the high water float was lifted
up. All inflow flows to the #2 oxidation ditch for denitrification (anoxic zone). Flow moves from
the middle of the anoxic zone to the outer 2 aerobic ditches for BOD removal and nitrification.
All brush rotors, except one in oxidation ditch # 3, were in service. The bearings in the out of
service rotor were being replaced and should be back in service within seven days. There was a
moderate amount of algae build up on the weirs in the 4 peripheral feed clarifiers. There were

blockages in most of the weirs however; no pin floc or solids were seen flowing over the weirs.
The center feed clarifier had no algae growth on the weirs. This office highly recommends a
more frequent cleaning schedule to prevent algae blockage on weirs. Sludge blanket in the # 1
clarifier (10 foot sidewall depth) was 1 foot. Sludge blanket in the #4 clarifier (11 foot sidewall
depth) was one -quarter foot. Effluent appeared clear flowing off all weirs in all 5 clarifiers. The
number 4 tertiary filter was out of service due to a broken hydrocone base. The number 2
tertiary filter was full of effluent due to plugged drain valves. The effluent is pumped to the other
operating tertiary filters for clarification. Effluent in the chlorine contact tank, dechlorination post
aeration tank, and at the outfall appeared clear with no solids. Freeboard level in the EQ basin
was 2.85 feet.
4. The Town of Benson Land Application Permit WQ0012514 was rescinded June 3, 2009. Marty
Morris stated that the Town will hire McGill Environmental Systems of NC, Inc. to compost the
wastewater treatment plant's biosolids at McGill's Delway, NC composting facility under their
W00006816 composting and distribution program. Atlantic Dewatering will dewater the sludge
at the wastewater treatment plant in December 2009. Sludge was last removed from the 3 MG
aerated sludge holding basin in 2003.
5. The laboratory was checked in a cursory manner. All instrument calibration logs are being
maintained on computer. An operator's logbook was available and being maintained. Fecal
coliform bath temperature was 44.3 degrees C and the laboratory refrigerator was'2.7 degrees
C. The influent and effluent flow meters were calibrated October 10, 2008 by Johnston Inc.
Influent sampler temperature was 2 degrees C and the effluent sampler temperature was 4
degrees C. All meters were calibrated by Johnston Inc. on 10/1312009.
6. Discharge Monitoring Reports (DMR's) for the period October 2008 to August 2009 were
reviewed for compliance with permit limits and monitoring requirements. There were no
violations listed for the review period.
7. Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the DMR for the month of August 2009. No discrepancies were noted.
Stormwater Permit NCG110062
8. Inspection of the stormwater outfalls and plant site was conducted at the same time as the CEI
wastewater treatment plant. Permit NCG110062 was reissued and became effective on June
01, 2008 and will- expire on May 31, 2013.
9. The Stormwater Pollution Prevention Plan (SWPPP) is reviewed annually. The SWPPP is not
compliant with Part II, Section A, 1 (a) that require the site plan 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.nc.us/tmdl/General 303d.htrn#Downloads North
Carolina TMDL documents can be found at the website
htto://h2o.enr.state.nc.us/tmdi/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.
10. There are three.stormwater outfalls listed for the facility:
a. Outfall 001 consists of drainage from the office/laboratory building and surrounding
roadway drainage that is conveyed by concrete pipe to a drainage structure near the
secondary clarifiers. This combined flow drains to a swampy area near the influent flow
structure. Water in the swamp area appeared rust colored most likely from iron bacteria

Benson WWTP CEI
Page 3
b. Stormwater from roof drainage, the building housing the reuse water tank and sodium
metabisulfate tank, and the shelter housing the chlorine gas tank is conveyed to the
stabilization lagoon through underground concrete pipe. This flow was thought to have
discharged offsite and is currently designated Outfall 002. This flow is connected to a
buried drainage pipe and conveyed to the EQ basin. Marty Morris stated he will send in
a request to rescind this outfall.
c. Outfall 003 consists of all other stormwater drains on the property that flow to Hannah
Creek. The outfall is next to the effluent discharge pipe. It appeared that there was no
discharge at the time of inspection though the pipe was submerged into the water.
11. Qualitative monitoring for Outfalls 001 and 003 was conducted on January 06, 2009.There is no
vehicle maintenance done on site. Employee training on clean-up procedures was completed in
July 2009. There have been no spills or bypasses since August 31, 2008.
I would like to thank Marty Morris and the staff of the wastewater treatment plant for their time and
assistance with this inspection. if you have any questions about this report or the inspection, please

Johnston County
Dear Mr. Langdon,
Coleen H. Sullins, Director
Division of Water Quality
On December 13, 2007 Mitch Hayes of the Raleigh Regional Office conducted a compliance
evaluation inspection of the subject facility. The assistance of Martin Morris grade WW-4 Operator in
Responsible Charge (ORC) and Steve Proctor grade WW-4 back-up ORC 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:
1. The subject permit was reissued and became effective March 01, 2006 and will expire April 30,
2008. A permit renewal application was received on October 31, 2007 and is currently under
review. Please continue to operate under the last issued permit until a new permit is issued.
2. The 1.9 MGD wastewater treatment facility consists of the following units: 2 earthen
equalization basins, arc bar (mechanical bar screen), grit chamber, 2 manual bar screens, influent
Parshall flume, ultrasonic flow meter, 3 screw pumps, 3 oxidation ditches (1 used for nutrient
removal), 4 secondary clarifiers (2 @ 10' depth, 2 @ I l' depth), 5 deep bed tertiary filters, dual
chlorine contact chamber, post aeration tank, effluent flow meter with ultrasonic sensor using a
2-feet rectangular weir with end contractions, sodium metabisulfite dechlorination, an effluent
reuse system providing irrigation to three athletic fields at the South Johnston County High
School, a 3 MG concrete lined aerated sludge basin with 3 floating aerators, and two stabilization
lagoons that also serves as influent flow storage.
3. At the time of inspection, one screw pump was out of service due to a broken gearbox and
oxidation ditch # I was out of service for cleaning and construction of a new rotor platform. The
number 5 tertiary filter was out of service due to broken hydrocone basses. The basses will be
replaced early next year along with new media. One-half of one oxidation is being operated as a
de-ox zone. A moderate amount of algae growth was noted on the secondary clarifier weirs. This
was causing some blockage of weirs and creating uneven flow over the weirs. This was noted in

last year's inspection. Sludge judge reading for secondary clarifier # 1 was 1 foot with a sidewall
depth of 10 feet. Sludge judge reading for secondary clarifier # 3 was 2 % feet with a sidewall
depth of 12 feet. Effluent flowing into the post aeration tank appeared clear. Effluent discharging
into Hannah Creek / swamp appeared clear with no visible solids or foam.
4. Upgrade to the increase the wastewater permitted capacity to 1.97 MGD has begun. Items noted
during the inspection included the following:
r7, Construction of new 14 feet sidewall depth, 15 feet in diameter secondary clarif er, mixed
liquor. effluent collection box and a new flows litter box downstream of the existing
.._. �.�.. , ... - oxidation ditches were under way.
■ Sidewalls for the influent structure, grit chamber, mechanical bar screen, and diversion
box have been raised above the 100-year flood plain. The existing secondary clarifiers
and the oxidation ditches sidewalls will be raised in 2008.
■ The existing 4-7.5 hp brush rotor drives in oxidation ditches # I and #3 will be replaced
with 4-15 hp drives. Oxidation ditches # 1 and #3 will also contain one new 15 hp rotor
with new brushes. As already noted, oxidation ditch #1 was out of service for the
construction of the new rotor platform.
■ All three -filter lift pumps will be upgraded and expanded to 30 hp each 2300 gpm.
■ Two existing screw pumps will be replaced with two new 5 hp 1,750 gpm screw pumps.
■ A new 30" D.I. parallel effluent outfall Iine has been installed and is in use. The new
outfall line is 5 feet offset from the existing 21" effluent outfall line.
■ A new yard hydrant and water meter for the reclaim water irrigation system has been
installed. When in operation, the effluent reclaim water spray irrigation system will apply
up to 1.97 MG per year on the 1.65 acres of land beside the oxidation ditch number 3.
Sludge in the 3 MG aerated sludge basin is allowed to settle and the supernatant is withdrawn
and pumped back into the headworks for reprocessing. The aerated sludge basin was last pump
out in 2003 by Atlantic Coast Contracting, Inc. The Class B sludge is disposed of in accordance
with permit WQ0012814.
6. The laboratory was checked in a cursory manner. All instrument calibration logs are being
maintained on computer. An operator's logbook was available and being maintained. Fecal
coliform bath temperature was 44.6 degrees C and the drying oven temperature was 106 degrees.
The influent and effluent flow meters were calibrated October 07, 2007. Influent sampler
temperature was 2 degrees C. and the effluent sampler temperature was 3 degrees C.
7. Discharge Monitoring Reports (DMR's) for the period August 2006 to September 2007 were
reviewed for compliance with permit limits and monitoring requirements. Total residual chlorine
permit limit was exceeded by 5% on 08/18/06. Flow was exceeded by 6% of the permit limit for
November 2006. These issues have been resolved and no further action is needed A pH value of
4.89 was recorded on 08/16/2007. This low pH value was found to be in error and an amended
DMR will be sent in with the correct value.
S. Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the DMR for the month of September 2007. No discrepancies were noted.
Stormwater Permit NCG110062
9. Inspection of the stormwater outfalls and plant site was conducted at the same time as the CEI
wastewater treatment plant. Permit NCGI10062 was issued and became effective on June 27,
2003 and will expire on April 30, 2008.

10. There are three outfalls listed for the facility:
a) Outfall 001 consists of drainage from the office/laboratory building and surrounding
roadway drainage that is conveyed by concrete pipe to a drainage structure near the
secondary clarifiers. This combined flow drains to a swampy area near the influent flow
structure. Water in the swamp area appeared somewhat cloudy most likely from previous
rain events.
b) Outfall 002 consists of roof drainage from the building housing the reuse water tank and
sodium metabisulfate tank and the shelter housing the chlorine gas tank. This flow was
thought to have drained offsite but was later discovered that it is conveyed to the
stabilization lagoon. You may request that Outfall 002 be removed from the permit
during permit renewal.
c) Outfall 003 consists of all other stormwater drains on the property and flows to Hannah
Creek. The outfall is next to the effluent discharge pipe. It appeared that there was no
discharge at the time of inspection though the pipe is half submerged into the water.
11. Qualitative monitoring for Outfalls 001 and 003 was conducted on March 16, 2007 and July 11,
2007. There is no vehicle maintenance done on site. There have been no spills for the 2006-2007
year.

Dear Mr. Langdon,
Alan W. Klimek, P.E.. Director
Division of Water Quality
On October 18, 2006, Mitch Hayes of the Raleigh Regional Office and Paul Rawls, DWQ Section
Chief of Surface Water Protection, conducted a compliance evaluation inspection of the subject facility.
The assistance of Martin Morris and Steve Proctor was helpful and 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:
1. The subject permit was reissued and became effective March 01, 2006 and will expire April 30,
2008. This permit included a modification to waive instream monitoring in Iight of participation
in the Lower Neuse Basin Association.
2. BIMS lists Steve Proctor; grade WW-4, as back-up Operator in Responsible Charge (b-ORC) for
the Class 4 Wastewater Treatment Plant. BIMS does not list any ORC for the WWTP. BIMS
lists Martin Morris; grade WW-4, as the b-ORC for Erin WWTP # 2. Please contact Steve Reid
in the Technical Assistance and Compliance Unit at 919,733.0026 to ensure Martin Morris is
properly listed as the ORC for Benson WWTP.
The Preliminary Engineering Report and Amendment Nos. 1, 2, 3 & 4 was approved March 4,
2006. This project includes improvements to the existing headworks; increasing the existing
influent pump station capacity; upgrade of the oxidation ditch brush aerators' providing a new
mixed liquor effluent collection box and a new flow splitter box downstream of the existing
oxidation ditches; construction of a new clarifier; upgrade of the existing filter pump station and
replacing filter media' improvement of the existing chlorination/dechlorination units' and an
effluent reuse system to apply up to 1,97 MG per year on the 1.65 acres of land at the wastewater
treatment facility.

5. At the time of inspection, one screw pump was out of service due to a broken gearbox and the
mechanical grit chamber was not operating. One-half of one oxidation is being operated as a de-
ox zone. The stilling well for the influent flow meter had a large volume of floating scum and
algae. This build up causes the flow meter to give an inaccurate reading of the influent flow. The
stilling well needs to be cleaned on more frequent bases. There was a moderate amount of algae
build up on the secondary clarifier weirs. This alga was causing uneven flow over the weirs and
some pin flock was noted. Sludge judge reading in the 10' and 12' secondary clarifiers was one-
half foot each. One deep bed tertiary filter was out of service to repair a broken air lateral. The
filter should be repaired this year. The effluent sampler hose had algae build up inside. The hose
needs to be cleaned or replaced. Paul Rawls suggested that the sampler hose could be covered
with a garden hose to block sunlight. The two equalization basins had more than two feet of
freeboard.
6. The aerated sludge basin was last pump out in 2003 by Atlantic Coast Contracting, Inc. The
Class B sludge is disposed of in accordance with permit WQ0012814.
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. The influent and effluent flow meters were calibrated October 04, 2006. Fecal
coliform bath temperature was 44.5.degrees C and the drying oven temperature was 105 degrees.
Discharge Monitoring Reports for the period July 2005 to July 2006 were reviewed for
compliance with permit limits and monitoring requirements. Permit limit violations for mercury
were recorded for June 21 and 30, 2006. These violations will be addressed in future
correspondence. It is noted that mercury is being reported in nanograms per liter (ng/l). Permit
requires that mercury be reported in micrograms per liter (ugll). Please begin reporting mercury
in ug/1. There were no other violations recorded for the review period.
9. 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 July 2006. No
discrepancies were noted.
10. Effluent entering Hannah Creek appeared clear with no solids, foam or odor.
Stormwater Pen -nit NCG 110062
11, Inspection of the stormwater outfalls and plant site was conducted at the same time as the CEI
wastewater treatment plant. Permit NCG 110062 was issued and became effective on June 27,
2003 and will expire on April 30, 2008,
12. There are three outfalls listed for the facility:
a) Outfall 001 consists of drainage from the office/laboratory building and surrounding
roadway drainage that is conveyed by concrete pipe to a drainage structure near the
secondary clarifiers. This combined flow drains to a swampy area near the influent flow
structure. Water in the swamp area appeared somewhat cloudy most likely from previous

Benson W WTP C61
Page 3
rain events. Mr. Morris stated that during severe rain events, water from the swamp area
floods into the drainage structure and floods the area surrounding the secondary clarifiers.
This office recommends that measures be taken to prevent water from flooding into the
drainage structure.
b) Outfall 002 consists of roof drainage from the building housing the reuse water tank and
sodium metabisulfate tank and the shelter housing the chlorine gas tank. This flow drains
offsite just past the fence. Water on the ground appeared muddy most likely from
previous rains.
c) Outfall 003 consists of all other stormwater drains on the property and flows to Hannah
Creek. The outfall is next to the effluent discharge pipe. Water in the Hannah Creek
appeared clear.
13. Qualitative monitoring for Outfalls 001, 002, and 003 was conducted on March 21, 2006 and
October 19, 2006. There is no vehicle maintenance done on site. There have been no spills for
the 2005-2006 year.

Plant is permitted for 1.9 MGD. BIMS does not list Martin Morris as ORC, only lists Steve Protor as bORC.
One screw pump, the ARC BAR, and one effluent tertiary sandfilter were not in operation. Stilling well for
influent flow meter had floating layer of scum that needs to be cleaned out. Secondary weirs had moderate
blockage due to algae growth causing some pin floc. Sludge was last removed from the aerated sludge
basin in 2003. Two mercury permit limit violations were reported in June 2006. No other permit violations
were recorded for the review period July 2005 - July 2006. Effluent appeared clear entering Hannah
Creek/Swamp with no detectable solids, foam, or odor.

Dear Sirs:
Michael F. Easley, Governor
William G. Ross Jr., Secretary
North Carolina Department of Environment and Natural Resources
September 26, 2006
Alan W. Klimek, P.E. Director
Division of Water Quality
Your letter of March 1, 2006, requested a General Stormwater Permit NCG 110000 for the Town of
Benson Wastewater Treatment Plant improvements. Since the Benson WWTP Plant already has a valid
permit, NCGI 100062, there is no requirement for an additional permit. Additionally, a compliance
evaluation inspection of the plant was conducted July 20, 2005, and the facility was found to be
compliant with all stormwater permit requirements.
Therefore, I am returning your application for the `new' permit. I understand that the $80.00.fee that
was submitted with this application was credited against the Town of Benson annual permit fee.
Sincerely,
William H. Diuguid, AICP

Annual Permit Fee
This annual fee is required by the North Carolina Administrative Code. It covers the administrative costs associated with your
permit. It is required of any person holding a permit for any time during the annual fee period, regardless of the facility's operating
status. Failure to pay the fee by the due date will subject the permit to revocation. Operating without a valid permit is a violation
and is subject to a $10,000 per day fine. If the permit is revoked and you later decide a permit is needed, you must reapply, with the
understanding the permit request may be denied due to changes in environmental, regulatory, or modeling conditions.

Permit was on site and available during inspection. Drains for the screenings
area, sludge loading station, and dumpster areas are piped to the influent pipe.
Outfall 1 drains road drains near the office/laboratory and parking lot to swamp.
Grass covers the pipe and the effluent could not be seen. Water does not appear to
be adversely affected. Outfall 2 drains the roof runoff from the building housing
the reuse water tank and sodium bisulfate tank. There is no containment area to
contain a possible spill. A 1400-pound of chlorine gas cylinder is stored under
shelter next to this building. The drainage area flows off site just past the
fence. There was no stormwater discharge. Outall 3 combines the other stormwater
road drains and discharges into Hanna Creek next to the wastewater discharge
outfall. Hanna Creek at the point of discharge is a swamp. The stormwater
discharging into the swamp had no color, foam or odor. All records for
inspections, employee training, spill response qualitative monitoring are
maintained. SWPPP is complete and spill response plan is up to date. There have
been no spills or violations.
