PART IV — EVALUATION AND RECOMMENDATIONS
1. The applicant is not requesting modification of the facility or increasing flow at this time.
2. A review of the compliance data did not reveal any significant violations.
3. Based upon the previous Compliance Evaluation Inspection (CEI) that was conducted on
April 15, 2014, all units were in service, and this facility continues to comply with the
requirements of the NPDES permit for wastewater treatment.
4. This Office recommends continuation of the Special Conditions for the Whole Effluent
Toxicity monitoring.
5. Based upon the above information, this Office recommends reissuance of the said permit
for the continued operation of an existing 4.0 MGD wastewater treatment facility
consisting of an influent pump station, mechanical bar screen, grit chamber, influent flow
monitoring, aerated equalization basin, flow splitter box, dual one million gallon per day
extended aeration basins with secondary clarification, a 2-MGD oxidation ditch with
secondary clarification, chlorine contact chamber, dechlorination, effluent force main,
cascade aeration, and two aerobic sludge digesters, and drying beds located at the
Laurinburg Leith Creek Wastewater Treatment plant, southeast of the City of Laurinburg,
in Scotland County.
6. According to 12 month average flow data, it appears that the WWTP is operating at 58%
capacity (flow capacity). There is a new industry that is scheduled to begin operation
toward the end of 2014. The industry has stated when they reach full production they
will be sending approximately 2MGD of wastewater to the WWTP. A copy of the
division's 80/90 rule (15A NCAC 02T .0118) was sent to the town with their inspection
letter.

Scotland County
Dear Mr. Ellis:
Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted
on. April 15, 2014. The Compliance Evaluation Inspection was conducted by Mark Brantley,
Environmental Senior Specialist, of the Fayetteville Regional Office. The facility was found to be in
Compliance with permit NC0020656. As a reminder, preservation of the Waters of the State can only be
achieved through consistent NPDES Permit compliance.
Comments
• Facility was clean and neat in appearance at the time of the inspection.
• Log books and maintenance logs were maintained.
• In anticipation of the new industry, FCC, the Division of Water Resources encourages the town to
prepare for the additional wastewater flow. Currently the WWTP is permitted for 4 MGD and
operated at 58% capacity during 2013. Some of the projected flow rates from FCC have been up
to 2MGD and this would put the Leith Creek WWTP at 100% capacity. Please review the
Division of Water Resources rule (attached below) on wastewater treatment capacities and make
plans as required.
15A NCAC 02T .0118 DEMONSTRATION OF FUTURE WASTEWATER TREATMENT
CAPACITIES
In order to insure that treatment, utilization, or disposal systems do not exceed their hydraulic treatment
capacities, no permits for sewer line extensions shall be issued to wastewater treatment systems owned or
operated by municipalities, counties, sanitary districts or public utilities unless they meet the following
requirements:
(1) Prior to exceeding 80 percent of the wastewater treatment system's permitted hydraulic capacity
(based on the average flow of the last calendar year), the permittee must submit an approvable
engineering evaluation of their future wastewater treatment, utilization, and disposal needs. This
evaluation must outline specific plans for meeting future wastewater treatment, utilization, or disposal

needs by either expansion of the existing system, elimination or reduction of extraneous flows, or water
conservation and must include the source(s) of funding for the improvements. If expansion is not
proposed or is proposed for a later date, a detailed justification must be made to the satisfaction of the
Director that wastewater treatment needs will be met based on past growth records and future growth
projections and, as appropriate, shall include conservation plans or other specific measures to achieve
waste flow reductions.
(2) Prior to exceeding 90 percent of the wastewater treatment, utilization, or disposal systems permitted
hydraulic capacity, (based on the last calendar year), the permittee must obtain all permits needed for the
expansion of the wastewater treatment, utilization, or disposal system and, if construction is needed,
submit approvable final plans and specifications for expansion including a construction schedule. If
expansion is not proposed or is proposed for a later date, a detailed justification must be made to the
satisfaction of the Director that wastewater treatment needs will be met based on past growth records and
future growth projections and, as appropriate, shall include conservation plans or other specific measures
to achieve waste flow reductions.
(3) The Director shall allow permits to be issued to facilities that are exceeding the 80 percent or 90
percent loading rates if the additional flow is not projected to result in the facility exceeding its permitted
hydraulic capacity, the facility is in compliance with all other permit limitations and requirements, and it
is demonstrated to the satisfaction of the Director that adequate progress is being made in developing the
needed engineering evaluations or plans and specifications. In determining the adequacy of the progress,
the Director shall consider the projected flows, the complexity and scope of the work to be completed and
any projected environmental impacts.

NC0020656 / WQ002526 / WQCS00062
Description of Collection System
The City of Laurinburg's collection system consists of 34 pump stations located
throughout the system. There are 123.7 miles of gravity sewers and 24 miles of
force mains. Our Leith Creek Plant consist of two types of treatment, one extended
aeration plant, consisting of 2 aeration basins, 2 clarifiers, 2 chlorine contact
chambers and one return sludge pump station with 3pumps, total capacity 2.0
million gallons per day (MGD).
The second plant is an oxidation ditch style with 1 clarifier, 1 chlorination point and 1
return sludge pump station with 3 dual speed pumps, total capacity 2.0 MGD, for a
total treatment capacity of 4.0 MGD. The facility has 2 aerobic digesters, (1)
150,000-gallon tank and (1) 650,000-gallon tank with course air diffusers.
Summary of System Performance for Calendar Year 2013
The discharge from the City of Laurinburg's Leith Creek Wastewater Treatment
Plant was in non-compliance for the months of June and July due to exceeding the
daily flow average of 4.000 MGD. The monthly average for the daily flows of June
was 4.464 MGD and for July 4.130 MGD. This was due to excessive rainfall.
Corrective Measures
The city is continually investigating inflow and infiltration problems to help improve
the system.
Summary of Sanitary Sewer Spills/Overflows:
Months Location Volume
07/03/2013 Manhole Old Lumberton Rd , 11640 Gallons
at Leith Creek
07/05/2013 Manhole at Lila Drive 9700 Gallons
The regional office has been notified. Applications are in process, to obtain grant
money to replace and rehab the sewer collection system.
*Note the overflows listed resulted in no environmental impact.
Notification
This Annual Performance Report will appear on the City of Laurinburg's web site
http://www.Iaurinburg.orq and a statement on our Consumer Confidence Report
(CCR) will inform citizens that the Annual Report is available via internet or upon
request.
Certification
I certify under penalty of law that this report is complete and accurate to the best of
my knowledge. I further certify that this report has been made available to the users
or customers of the named system and that those users have been notified of its
