SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Cerialaphnia dubia at an effluent concentration of 31%.
The permit holder shall perform at a minimum, quarwrly monitoring using test procedures outlined in the "North
Carolina Cezarlaphrua Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The tests will be performed during the nvnths jFebruary, May, August, and November. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the fast 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 -February 1998) or subsequent
versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have
a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods,
exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the
pass/fail results and TI1P3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days
after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total
residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection
of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
permittee will complete the information located at the top of the aquatic toxicity (Al) test form indicating the facility
name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited
above.Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month. Should any test data from this monitoring requirement or tests performed by the
North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.

SUMMARY
• This facility is a major municipal treatment plant operating in Scotland County
that serves 15,983 people in the City of Laurinburg. City has a separate sewer
collection system. The facility has permitted flow of 4.0 MGD discharging into the
Big Shoe Heel Creek. For the past 2 years annual average flow varied within the
range of 1.68-2.54 MGD. This facility has been discharging since 1970. There is a
small industrial component to the discharge, but no pretreatment program is
required due to lack of SIUs. Residuals are land applied under permit
WQ0002526.
REASONABLE POTENTIAL ANALYSIS
The following parameters are monitored through the permit: Cu, Zn, F, and Hg.
Reasonable potential analysis was conducted for: Cr, Cu, F, Hg, Ni, and Zn(see

COMPLIANCE SUMMARY:
DMRs have been reviewed for the period January 2001 through April 2004. The
Facility has a good compliance record. During the review period, the following NOVs
(notices of violation) have been issued: 05/05/03 - TSS, 03/05/03 - improper
operation of secondary clarifier.
A compliance evaluation inspection (CEI) conducted on February 10, 2004 found a
few minor problems. The CEI conducted on 6/26/03 determined that the facility is
well maintained and properly operated.
INSTREAM MONITORING:
Instream monitoring is required for temperature, fecal conforms, conductivity,
and dissolved oxygen. An analysis of DO, temperature and conductivity data
showed that the facility has some negative influence on DO level in the stream
(table is attached). Data does not indicate that the facility has a significant
impact on conductivity and temperature.
PROPOSED CHANGES:
• Monitoring Frequencies: No changes are proposed.
• Limits: The statistical analysis of the mercury effluent data showed reasonable
potential to exceed water quality standard. However, the limit will not be
implemented due to a limited data set. The data will be reevaluated during the
next renewal. The daily maximum total residual chlorine limit and weekly
average NH3-N limit have been added to the permit.
• Priority pollutant monitoring on an annual basis has been added to fulfill the
permit application requirement in the future.
The existing monitoring frequency for zinc, and copper remains unchanged. Due to
the facility's toxicity record, limits for these action level standards will not be
implemented, but monitoring will remain. All other parameters evaluated showed no
reasonable potential to exceed the instream water quality limits or federal criteria.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: August 4, 2004 (est.)
Permit Scheduled to Issue: September 27, 2004 (est.)
STATE CONTACT:
If you have any questions on any of the above information or on the attached permit,

Dear Mrs. Stephens:

OFFICE OF SUPERINTENDENT
WATER & WASTEWATER PLANT
MAR 3 2004
Enclosed is the NPDES Form 2A Application for Permit Number NC0020656, the
City of Laurinburg's Leith Creek WWTP. We are requesting a renewal for this permit,
and the only changes at this facility since the last renewal are as follows:
1. The two fifty foot diameter clarifiers on the extended aeration side of the plant
have been overhauled with new Westech clarifier drive units, new weir plates and
new v-notch weirs.
2. We discontinued the use of chlorine gas by installing a new sodium hypochlorite
disinfection system that includes a 6000 gallon bulk storage tank, two chemical
transfer pumps, two pulsafeeder chemical pumps and two 200-gallon day tanks
for diluting the 15% sodium hypochlorite that we receive for our bulk tank. We
consistently feed a 7% solution from our day tanks for disinfection purposes.
In response to question B 1 on page 7 of the application our Governing Board (City
Council) adopted a five-year Capital Improvement plan to improve our pump stations and
collection system to address our Inflow/Infiltration problems. This was also part of the
requirements for the Wastewater Collection System Permit (WQCS00062). Enclosed is
a copy of the CIP that council adopted on March 19, 2002.
The Authorized Representative for this facility is Mr. Joseph R. Huffman, City Manager.
Please make note of this since Mr. Peter G. Vandenberg retired in 1999.
Sludge that is generated at this facility is land applied at Laurinburg-Maxton Airport in
connection with Land Application of Residuals Permit Number WQ0002526. Leith
Creek WWTP has two aerobic digesters with a total volume of 800,000 gallons. 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.
603 LAUCHWOOD DRIVE P.O. BOX 249 ® LAURINBURG, N.C. 28352 919/277-0214

We have performed one PPA analysis for this renewal process (results included) and
have scheduled with The Best Lab in Lumberton, NC to conduct two additional PPA's in
April and June of 2004, as we receive these results we will forward them to your office.
We have also performed one toxicity test with an additional organism (Fathead Minnow)
enclosed for this renewal. Based on a conversation that I had with Ms. Susan Wilson of
NPDES permitting unit she advised me that these second organisms can be performed
sooner than our regular toxicity test. Therefore, I have scheduled to conduct the Fathead
Minnow Toxicity Test in March, April and May 2004. The May Toxicity test will be
performed with our regularly scheduled toxicity test.
If you have any questions concerning this Renewal request please contact me at 910-277-
0214
Sincerely,
Robert E. Ellis

MEMORANDUM
To: NPDES Unit Staff
From: Toya Fields
Subject: Summary of 7/24/03 Lumber River Basin Meeting
Potential Permit Modifications Needed for Assessed Facilities (August 1999- May 2003).
NC0005762 West Point Stevens, Inc
The Wagram plant does not provide chlorination. As a result the permittee had multiple civil
assessments for violations over the two-year period. One whole effluent toxicity violation and
seven fecal limit violations (including one for fecal and pH) were recorded. Their fines totaled
$6526.99.
Recommended action: Compel chlorination and dechlorination.
NC0020729 Town of Fair Bluff
This facility has incurred civil assessments for limit violations of flow, fecal, TRC, and BOD.
Fines total $6901.73 (reduced to $3151.73). Concerns include are grease accumulations in the
plant, I/I, grit, and reduced retention time. This facility has had a sewer moratorium since 7/98
due to I/I problems. Their fecal violations can be attributed to inadequate Cl feed equipment.
Recommended action: Place wastewater management plan (WWMP) requirement in permit.
Specifically require a facilities assessment and an optimization plan for grit removal/disposal and
chlorination. Also add oil and grease monitoring.
NC0044725 Laurinburg-Maxton Airport Commission
This facility has had civil assessments for limit violations totaling $2701.91. All three
assessments were for fecal coliform levels. Though the plant upgrades are complete, the WWTP
failed a 3/01 toxicity test.
Recommended action: Require WWMP. specifically a Biosolids Management Plan.
NC0026921 Town of Parkton
Facility has been assessed civil assessments for whole effluent toxicity and limit violations on
eleven occasions. Causes of limit violations were fecal, TRC, BOD and Hg. The assessments total
$26,075.45. Fayetteville Regional Office continues to work with the ORC. The facility has
received a CWMTF grant for I/I.
The facility may be connecting to Red Springs (NC0025577).
* Connection to Fayetteville PWC WWTP is another possibility.
Recommended action: Add EAA requirement.

NC0049514 Pilkington North America Inc
Permittee has been assessed for civil violations on eight separate occasions. The limit violations
were for TP, O&G, pH, and TSS. Fines total $7798.20. The facility is investigating the cause of
their oil and grease problems and have discussed connecting to LMAC (NC0044725).
Recommended action: Place EAA requirement in permit. The Facility needs to evaluate the
possibility of connecting to LMAC.
NC0021881 Town of Lake Waccamaw
Permittee has had three civil assessments for fecal limit violations, one of which also included a
violation of NH3N limits. The town has been fined for $2121.65. An unsatisfactory sludge storage
capacity at the plant contributes to loss of solids during heavy rain events. In 2001 the sludge
buildup was observed in the receiving stream. The permittee was also non -compliant with its
toxicity limit in 12/02 and 2/03, and there are 1/I problems within the collection system.
Recommended action: Require WWMP, specifically a Biosolids Management Plan.
NC0021920 City of Whiteville
This facility has been assessed for civil violations of whole effluent toxicity on four occasions.
Penalties total $9102.72. An ATC was issued in 2/03 for the installation of a grit removal facility
(plant experienced problems with sand accumulation). Two letters sent in 2/03 and 4/03
expressed concerns regarding the structural integrity of the plant's aeration and oxidation ditches.
The system also has problems with Zn from a SIU (Conflande) and associated storm water issues.
Recommended action: Require WWMP, specifically a Biosolids Management Plan.
NC0020656 Laurinburg Leiths Creek
This permittee has not violated its permit requirements.
Recommended action: Require WWMP, specifically a Biosolids Management Plan.
