A. (2) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 31%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be
performed during the months of February, May, August and November. These months
signify the first month of each three-month toxicity testing quarter assigned to the facility.
Effluent sampling for this testing must be obtained during representative effluent discharge
and shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
If the test procedure performed as the first test of any single quarter results in a failure
or ChV below the permit limit, then multiple -concentration testing shall be performed
at a minimum, in each of the two following months as described in "North Carolina
Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -December 2010) or
subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the

submitted to the following address: NC DENR / DWR / Central Files, 1617 Mail Service
Center, Raleigh, North Carolina 27699-1617.
Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note
that Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed
above are also subject to additional toxicity testing requirements specified in Federal
Regulation 40 CFR 122.21(j)(5). The US EPA requires four (4) toxicity tests for a test organism
other than the test species currently required in this permit. The multiple species tests should
be conducted either quarterly for a 12-month period prior to submittal of the permit renewal
application, or four tests performed at least annually in the four and one half year period prior
to the application. These tests shall be performed for acute or chronic toxicity, whichever is
specified in this permit. The multiple species toxicity test results shall be filed with the
Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting
the additional toxicity tests and reporting requirements. Results should also be summarized
in Part E (Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the
permit renewal application to the NPDES Permitting Unit.
A. (4.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and specify that, if a state does not establish a system to receive such submittals, then
permittees must submit DMRs electronically to the Environmental Protection Agency (EPA).
The Division anticipates that these regulations will be adopted and is beginning
implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II
of this permit (Standard Conditions for NPDES Permits) :
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports

Beginning no later than 270 days from the effective date of this permit, the permittee shall
begin reporting discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each
month and submitted electronically using eDMR. The eDMR system allows permitted
Page 7 of 10

Permit NC0020656
facilities to enter monitoring data and submit DMRs electronically using the internet. Until
such time that the state's eDMR application is compliant with EPA's Cross -Media
Electronic Reporting Regulation (CROMERR), permittees will be required to submit all
discharge monitoring data to the state electronically using eDMR and will be required to
complete the eDMR submission by printing, signing, and submitting one signed original
and a copy of the computer printed eDMR to the following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to
the facility being physically located in an area where less than 10 percent of the
households have broadband access, then a temporary waiver from the NPDES electronic
reporting requirements may be granted and discharge monitoring data may be submitted
on paper DMR forms (MR 1, 1.1, 2, 3) or alternative forms approved by the Director.
Duplicate signed copies shall be submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the
date the facility would be required under this permit to begin using eDMR. Temporary
waivers shall be valid for twelve (12) months and shall thereupon expire. At such time,
DMRs shall be submitted electronically to the Division unless the permittee re -applies for
and is granted a new temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic
reporting requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Regardless of the submission method, the first DMR is due on the last day of the month
following the issuance of the permit or in the case of a new facility, on the last day of the
month following the commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B.
(11.) (d)l
All eDMRs submitted to the permit issuing authority shall be signed by a person described
in Part II, Section B. (11.) (a) or by a duly authorized representative of that person as
described in Part II, Section B. (11.)(b). A person, and not a position, must be delegated
signatory authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR
user account and login credentials to access the eDMR system. For more information on
North Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account,

Reasonable Potential Analysis (RPA)
A reasonable potential analysis (RPA) was performed for copper and zinc. There is reasonable potential
to exceed the water quality standard for both parameters. See attached RPA results.
Mercury
A mercury evaluation was conducted in accordance with the Permitting Guidance developed for the
implementation of the Statewide Mercury TMDL. Based on available dilution the water quality based.
effluent limitation (WQBEL) for mercury is 39 ng/1. The technology based effluent limit (TBEL) is 47
ng/1. The data for mercury for the past five years shows there is reasonable potential to exceed the water
quality limit (See attached Mercury RPA) The limit of 39 ng/1 will remain in the permit but as an annual
average. A Mercury Minimization Plan will also be required in the permit. A special condition was be
added to the permit describing the requirements for the MMP.
Compliance
For the period of January 2010 to May 2014 the facility received two Notices of Violaton for exceedances
of the mercury monthly limit and one Notice of Deficiency for an exceedance of TSS weekly average.
Toxicity Testing
Current requirement: Chronic P/F @ 31%. The facility has excellent compliance with the toxicity tests.
Instream Monitoring
The facility collects instream data for temperature, pH, dissolved oxygen, conductivity and fecal coliform.
Data for Fecal coliform show values above the water quality standard for both upstream and downstream
locations. Dissolved oxygen was frequently above the water quality standard in the second
Downstream location.

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.

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.

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 VWVfP 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 VWVfP 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.
