Dear Mr. Ellis:
Enclosed you will find a copy of the Compliance Evaluation Inspection report for the
inspection that was conducted on February 3, 2011. A tour of the Wastewater Treatment Plant
was conducted as part of the inspection. All observations are in Part D: Summary of
Findings/Comments of this inspection report.
Suggestion:
1. Please install flow -paced dosage for chlorine and sulfur dioxide. There may be long-tenu
cost savings realized by the Laurinburg Leith Creek Wastewater Treatment Plant by the
use of flow proportional dosage equipment for chlorine and sulfur dioxide. The reasoning
is that during low flow conditions occurring during the evening hours, the dosage of the
chlorine and the sulfur dioxide would automatically be reduced, thereby reducing the cost
for the disinfectant and de -chlorinating agent. An additional benefit would be that the
optimum dosages would be maintained throughout the day and night.
Recommendations:
1. Please repair the holes that were in the walls of the chlorine contact chamber. (Please see
the photos that are included in this report.)
2. Please repair the bracket on the weir of the aeration basin.
3. Please repair the grit pump that was out -of -service during this CEI.

Requirements:
1. I observed that a high-level flow switch would activate the pump in the sodium
hypochlorite storage tank containment area at a preset liquid level. It appeared that the
secondary containment would not contain a spill without part of the spill being pumped
pass the containment wall and into the storm drain that flowed to Leith Creek. Please
follow the requirements for Secondary Containment that is in the Laurinburg Leith Creek
Wastewater Treatment Plant's General Stomiwater Permit NCG110123, Part II, Section
A, 2, (b) Secondary Containment Requirements and Records: "If the secondary
containment devices are connected directly to stoiinwater conveyance systems, the
connection shall be controlled by manually activated valves or other similar devices
(which shall be secured closed with a locking mechanism), and any stoiuiwater that
accumulates in the containment area shall be at a minimum visually observed for color,
foam, outfall staining, visible sheens and dry weather flow, prior to release of the
accumulated stormwater".
2. Beginning with July 2010, please send to DWQ the amended Effluent 001 DMRs so that
they are in agreement with the Suspended Residue Requirement for minimum reporting
limit that is stated in the Laboratory Certification report (dated June 9, 2010). Please
send the amended DMRs and a copy of each to Mail Service Center 1617 in Raleigh. If
you have questions concerning the minimum reporting limit, please phone Tonja Springer
[phone], ext 241. The amended DMRs are asked as according to NPDES Permit
NC0020656, Part II, Section E, (8): "Where the Peimiittee becomes aware that it failed to
submit any relevant facts in a permit application, or submitted incorrect infoiuiation in a
permit application or in any report to the Director, it shall promptly submit such facts or
information [40 CFR 122.41 (1) (8)]."
3. Please immediately implement a Plan -Of -Action to prevent spillage of sludge onto the
ground when transferring from the Sludge Holding Tank or the Aerobic Digester, and
please send this Office the Leith Creek WWTP's procedure to prevent sludge onto the
ground, and possibly into the stoiui drain.
4. Please explain why the sludge was spilled near each of the sludge holding tanks during
transfer to the sludge hauling truck.
5. Please answer the following nine questions:
A. Please explain why there was 12 feet of sludge blanket in Clarifier #3 at the time of
the CEI, as I understood that the' small holding tank was emptied on January 21, and
was filled and decanted daily.
B. Are there plans for adding a new 650,000 digester (#3), as was in the February 2005
request from Hobbs, Upchurch and Associates?
C. What are the plans for the unused sludge hauling truck that is located at the WWTP?
D. According to the NPDES NC0020656 permit application, dated February 5, 2009,
you try to land apply 3.2 million gallons each year. Please explain why the actual

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Enclosed you will find a copy of the Compliance Evaluation Inspection report for the inspection that was
conducted on February 3, 2011. A tour of the Wastewater Treatment Plant was conducted as part of the
inspection. All observations are in Part D: Summary of Findings/Comments of this inspection report.
The following notes were taken during a tour of the Wastewater Treatment Plant that was conducted as part
of the inspection. The automatic bar screen and hydraulic press appeared to be in good working condition.
The automatic bar screen could be operated in either the automatic or the manual modes. The grit chamber
unit was operational; however, one grit pump was out -of -service for an electrical repair. When the
automatic dialer for the influent pump station was activated, the water treatment plantwas dialed first, then
the police station, and finally the on -call operator. The wastewater treatment plant operators were on -site
from 7 AM until 4 PM, Monday through Friday. On weekends, the on -call operator routinely checked the
pump stations, the WWTP, and performed the weekend laboratory work. Both influent pumps were
operational. The pumps were automatically rotated each time that the influent wastewater switch was
activated. The influent 24-hour composite sampler and refrigerator were located near the two influent
Parshall Flumes; and, each flume had an ultrasonic flow meter. Both the influent pump station generator
and the WWTP generator were exercised under -load for approximately 1-to 1 1/2 hours by means of the
manual switchover on the first Monday of each month. Both generators were capable of automatic
switchover.if the electrical power failed. The generator's fuel tanks were maintained at 3/ full. The
generator for the WWTP was capable of handling all of the wastewater treatment plant. Every morning, the
auto dialer and the EQ pumps were checked by shutting off all of the influent pumps at the influent pump
station, thereby allowing the influent wastewater level to increase. This activated the float switch for the EQ
pump station, and it also activated the auto dialer. This daily test resulted in the transfer of approximately
1,000 gallons of raw wastewater into the EQ basin. On each Thursday or Friday, the EQ basin was drained
of the raw wastewater that had accumulated during the week of daily testing. The oxidation ditch and the
clarifier #3 were both operational. On the extended aeration side of the WWTP, the aerators were turned on
and off by a timer. The DO was routinely between 1.0 to 2.0 mg/L. The scum that was collected at
clarifiers #1 and #2 flowed to the head of Side 1. The scum that was collected at clarifier #3 (on Side Two)
was pumped back to the splitter mixing box near the headworks, and was later pumped back into all three
aeration basins. Clarifier weirs were swept during routine daily cleaning. On "Side One", the chlorine contact
chamber was pumped out whenever the solids depth in the chlorine contact chamber was between 10 to 12
inches; according to Mr. Odum, this occurred approximately every three days. During the cleaning
procedure, the contents of the chlorine contact chamber flowed to the wet well, and then the solids were
pumped to the head of the plant. The total depth of the chlorine contact chamber was thirteen feet. The
automatic switchover units for the chlorine and sulfur dioxide cylinders were both operational. Neither the
sulfur dioxide dechlor nor the sodium hypochlorite disinfectant were set up for flow paced dosage. At the
time of this CEI, EMA Resources was in the process of hauling sludge from the City of Laurinburg's WWTP
to the land application site at LMAC. This hauling event began on January 21, 2011. Approximately
810,000 gallons was hauled. The small holding tank was emptied on January 21 st (for a depth of 9-feet).
It was filled and decanted daily. The large holding tank was 20-feet deep, and 15-feet of sludge had been
already been taken out by the time of this CEI. According to Mr. Odum, they had previously intended to
haul sludge during December 2010, but they were delayed from hauling due to the very cold and wet
weather conditions. The effluent flow meter was not working at the time of this CEI. It had stopped
working on January 26, 2011 (eight days before the CEI). Therefore, the flow proportional 24-hour
composite sample was also not working. According to Mr. Odum, the Effluent 24-hour composite sampler
was delivering 200 mL of Effluent per 30 minutes. J. S. Desmute, Inc. had been contacted to repair the
flow meter, and he was expected to arrive two days before this inspection. According to the ORC, the
flowmeter was repaired on February 3, 2011.

Dear Mrs. Sprinkle:
Enclosed is the NPDES koln LA Application fo trmit Number NC0020656, the
City of Laurinburg's Leith, Creek WWTP.•
We are requesting a renewal for this permit.
•
y^,wry+ :.: cr,2r•
Question B 1: The governing board originally adopted the CIP March 19, 2002. Since
•then the CIP has been updated an nually to re lect the needs of the collection system and
pump stations to help eliminate Inflow& Iiifiltration:concerns. Co es of the current CIP
are attached for your evjew
The Authorized Representatrv;.
`- r Craig Honeycutt, City Manager.
Sludge that is generated.:at this>.facility'is land applied at Laurinburg 'Maxton Airport in
connection with Land Application. ofResiduals Permit Numbex`WQ0002526: Leith
Creek WWTP has two aerobic digesters with a total volume of 80kr,g00 gallons. We try
to perform four land application events per`ye it for�ajotal of 3.2g`mjllion gallons.
However if we needtoa 1y more we will lime stabilize to perform these events more
frequently.
We have one additional fathead minnow toxicity test to complete for the permit renewal
requirements. This test is being analyzed by our contract lab at this time. We will
forward the results as soon as we receive them.
If you have any questions concerning this Renewal request please contact me at 910-277-

Dear Mr. Lopez:

bENI -fRO
APR 20 2011
This letter is in response to'.the inspection that you conducted on February 3, 2011 at our
facility.
Suggestion:
1.
I would agree in the long run to install a flow paced dosage £or chlorine and -
sulfur dioxide�system would bebeneficial However there is not an economical
way to install this, -system: without'a major investment. Currently the flow meter
we would have to incorporate.ii orderrto operate a flow -paced system is at the
cascade aerator and we do nOthalve'a. line of ition rfrom the aerator back
to the treatment plant.
Recommendations:
1. We are in the process of locating a contractor who can repair the contact chamber.
Personally I don't see this being a major issue and the reason being is the contact
chamber is in service way more that they are being pumped out. Therefore, the
only time the leaks occur is when one side is down for cleaning purposes.
2. We are in the process of scheduling repair work on the aeration with a broken
bracket on the weir of the aeration basin. This will be repaired during this project.
3. The grit pump at the influent pump station is back in service.
603 LAUCHWOOD DRIVE • P.O. BOX 249 • LAURINBURG, N.C. 28353 • PHONE: [phone] • FAX: [phone]

Requirements:
1. In order to comply with our Storm Water Permit at Leith Creek we will manually
activate valves and the sump pump in the containment area as needed.
2. Please see the attached corrected DMR copies for July 2010 — December 2010.
We also submitted these corrected copies to Raleigh, NC.
3. The sludge that was observed on the ground around the digesters was not caused
by the transferring of the sludge from the digesters to the tankers. It was the result
of the breaking down of the piping from the transfer pump after the pumping was
finished. The sludge was cleaned up using the City's vacuum truck and lime was
applied to the areas. During future sludge removal events we will build a
temporary birm around the storm drain to prevent any sludge runoff reaching the
storm drain.
4. The sludge spilled was the result of breaking down of the piping from the transfer
pump after the pumping was finished. There is always some residual sludge left
in the piping and it is impossible not to get any on the ground. Any sludge that is
spilled is cleaned up and lime is applied to the area.
5.
A. We had scheduled for the sludge to be removed from the plant in
December, however due to our haulers running behind because of the weather
conditions we were maintaining more sludge than normal. The small digester
(#1) only holds 131,880 gallons and once it is full we are only capable of
decanting off 28,260 gallons at a time. Also during this time the large digester
(#2) which holds 680,120 gallons was being emptied by the contracted sludge
hauler.
B. We request monies for a new 650,000 digester every year in our budget
request.
C. We are in the process of trying to partner with a local farmer to begin
using the sludge hauler at the Wastewater Treatment Plant.
D. We try to land apply 3.2 million gallons each year, that amount is based on
if we land apply four times during the year. Due to utilizing our drying
beds throughout the year and the fact that our influent flow has decreased
our sludge production has decreased. However we feel it is prudent that
3.2 million gallons be the permitted amount so that we have an adequate
parameter to work within. From 2006 — 2010 1,260,871 gallons of sludge
was applied to the drying beds.
E. The decant from the small digester (#1) flows to the RAS wet well on Side
#1 of the plant.
F. The decant from the large digester (#2) flows to RAS wet well on Side #1
of the plant.
G. The side #1 and side #2 can be wasted to the small digester.

H. The Side #1 and Side #2 RAS pump stations sends Waste Activated
Sludge to digester #2.
I. The flow does not flow between the two digesters.
Please call me if you have any questions.
Sincerely,
Robert Ellis

Subject: Leith Creek response letter the CEI report requirements for CEI performed on February 3,
2011
Hi Belinda,
I reviewed Robert Ellis's response letter that FRO received on April 20, 2011. You asked if they addressed all
the issues that I noted in the CEI. They did, and some of Robert EIIis's answers are adequate, but there were several
that were not (as the below list may indicate).
1. They are "in the process of locating a contractor who can repair the holes in the contact chamber". I think
that one of the problems is that the
holes in the contact chamber are directly under a small building, so I wonder about the structural integrity for
the support of the building.
In addition, the holes, indicate that they are not maintaining the contact chamber.
15A NCAC 08G .0204 (3): "operate and maintain the system efficiently and attempt to insure the compliance
of the system ..."
2. They are "in the process" of scheduling repair work on the broken bracket on the weir of the aeration basin (old plant
side).
3. They "are in the process of trying to partner with a local farmer to begin using the sludge hauler" tank truck that is
located at the WWTP (and that has never been used).
4. They think that they cannot improve their procedure for the prevention of sludge spillage when breaking down the
piping when hauling sludge. "The sludge spilled was the result of breaking down of the piping from the transfer pump
after the pumping was finished. There is always some residual sludge left in the piping and it is impossible not to get
any on the ground. Any sludge that is spilled is cleaned up and lime is applied to the area." (There are portable
containment items available.)
5. It seems highly unlikely that they will strongly pursue building a new digester in the near future. "We request
monies for a new 650,000 digester every year in our budget request."
6. Concerning my question as to why #3 clarifier sludge blanket was 12 feet deep, Robert Ellis responded that "due to
our haulers running behind because of the weather conditions we were maintaining more sludge than normal" ... "we
are only capable of decanting off 28,260 gallons at a time" from the small digester. "Also during this time the large
digester (#2) which holds 680,120 gallons was being emptied by the contracted sludge hauler". (According to Ricky, the
small digester had been emptied on January 215L, which was 12 days prior to this CEI, and they filled and decanted
28,260 gallons from the small digester on a daily basis). In my opinion, they were too close to going over the weir in #3
clarifier. I regret that I didn't request and watch Ricky take sludge judge readings on the other two clarifiers when I did
the CEI (because now I suspect that they were also near to going over the clarifier weirs). I should have verified the
complete status of the solids. Instead, I was satisfied that they were finally in the process of hauling sludge and I was
relieved that solids were not going out Plant Outfall 001 when I did the CEI.
7. Robert Ellis said that the sludge production has decreased because the influent flow has decreased. (I think that
there is a possibility that there is less food coming in from the industries). He said: "However we feel it is prudent that
3.2 million gallons be the permitted amount so that we have an adequate parameter to work within. From 2006 — 2010
1,260,871 gallons of sludge was applied to the drying beds."
The following are the actual amounts of sludge that were land applied during 2006 to 2010:

5,761,000 + 1,260,871 =
7,021,871 gallons
7,021,871 gal / 5 yrs =
1,404,374 gal/yr to land
ap & to drying beds
The 1,404,374 gal/year average does not agree with what Robert Ellis said in his February 5, 2009 cover letter for the
NPDES Permit Renewal (NC0020656): "We try to perform four land application events per year for a total of 3.2 million
gallons. However if we need to apply more we will lime stabilize to perform these events more frequently". It doesn't
agree because for the last three years, he only land applied approximately 806,000 gallons per year. Then, he holds the
sludge from the drying beds for an indefinite number of years before he land applies it. But, even if he land applied all
the wet sludge that goes to the drying beds plus all that is land applied as wet sludge, the volume is half of what he said
that he would do: 1,404,374 gallons (for the average of 5 years) instead of 3,200,000 gallons.
Any suggestions on how I should proceed with his response letter; etc. would be much appreciated.
Thanks,
Dale
