CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Cerioduphnia dubia at an effluent concentration of 13%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia 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 months of March, June, September, and December. 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 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 -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 THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quality 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 (AT) 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. Permit Number: NC0020231 PART I. A(3) SPECIAL CONDITION For Association members: Limits on total phosphorus and total nitrogen have not been included at this time because the facility is participating in the nonpoint source trading option outlined in the Tar Pamlico NSW Implementation Strategy Phase II, which was adopted December 8, 1994. If compliance with any element of this strategy, or subsequent approved revisions to the strategy is not maintained, the Division reserves the right to reopen this permit to include nutrient limits. If requirements other than those listed in this NPDES permit arc adopted as part of a future revision to the strategy, the Division reserves the right to reopen this permit to include these requirements. ri1/1 Jl I l o�. DENR/DWQ FACT SHEET FOR NPDES PERMIT DEVELOPMENT NPDES No. NC0020231 Facility Information Applicant/Facility Name: Town of Louisburg Applicant Address: 110 West Nash Street Facility Address: NC Hwy 56 East Permitted Flow 1.37 MGD Type of Waste: Domestic and -light -industrial Facility/Permit Status: Renewal County: Franklin Miscellaneous Receiving Stream: Tar River Regional Office: Raleigh Stream Classification: WS-V NSW USGS Topo Quad: C25SE 303(d) Listed?: Yes — Fecal coliform j ' ' Permit Writer: Michael Myers Subbasin: 03-03-01 Date: January 3, 2000 Drainage Area (mi2): 437 ..;, Summer 7Q10 (cfs) 14 Winter 7Q 10 (cfs): Average Flow (cfs): 460 IWC (%): 13 Primary SIC Code: 4952 SUMMARY The Tar River Water Reclamation Facility is located on North Carolina Highway 56 East, south of Louisburg in Franklin County. The facility has a permitted flow of 1.37 MGD, which discharges through one outfall (001). The influent wastewater is composed of domestic (95%) and light industrial (5%). The treatment plant is equipped with the following unit processes: aerated grit/grease removal, anaerobic selector, dual oxidation ditches (BioDeNioPho Process), dual secondary classifiers, 3 cell tertiary filters, UV disinfection, sludge thickener, aerobic digester and ultrasonic flow meter. This is a Class III Biological Facility, with a IWC of 13%. 5k-or r The Tar River Water Reclamation Facility discharges into the -Tar River in the Tar -Pamlico River Basin. At the point of discharge the Tar River is classified as.WS-V NS\V. waters. The outfall is located in a reach of the river, which has been placed on the State's 303(list as being impaired for fecal coliform. The major contributors to this impairment are the numerous the and dairy operations located in the area. '1" ,' % — `iU, Of The Town of Louisburg has had no compliance problems over the past four years and according to the staff and compliance inspection reports appears to be well maintained and operated. The facility is currently required to monitor for lead and oil and grease. A reasonable potential analysis, conducted using the facilities Discharge Monitoring Report data, suggest that there is a reasonable potential for the facility to exceed the water quality standard for lead. Therefore, a daily maximum limit for lead is recommended as a condition for the permit. Four industries Boston Gear, Cal -Maine Food; -Inc., Murphy House Pac -age Plant, and Almet Lawnlite discharge to the POTW. Because of the nature of these industries, it is recommended that oil and grease monitoring remain in the permit. t" J fib!J Town of Louisburg, NC0020231, Fact Sheet NPDES Permit Renewal Page 1 TOXICITY TESTING: Current Requirement: Quarterly Chronic Toxicity (Ceriodaphnia) P/F at 13%. Recommended Requirement: Quarterly Chronic Toxicity (Ceriodaphnia) P/F at 13%. COMPLIANCE SUMMARY: 1999: 9/99 — The monthly average for flow exceeded the facilities permitted limit. Through 10/99 the facility averaged 69.5 % of their permitted flow. 1998: No compliance issues. The facility operated at 57.8% of their permitted flow. 1997: Late with the December chronic toxicity report. The facility operated at 47.9% of their permitted flow. 6/97 — NOD issued; the influent and effluent samplers were not properly maintaining temperature at 4 °C. 1996: No compliance issues. The facility operated at 50.0 % of their permitted flow. INSTREAM MONITORING: Currently, the facility is required to monitor fecal coliform, dissolved oxygen, temperature, and conductivity, upstream and downstream of the outfall-three times per week during June, July, August and -Se iember and once per week during the rest of the year. The upstream location is 100 feet upstream of the outfall and the downstream location is at NCSR 1001. PROPOSED CHANGES: According to the Division's analysis the Tar River Water Reclamation Facility has a reasonable potential to exceed the water quality standard for lead. Therefore, the NPDES permit for the referenced facility contains a daily maximum limit for lead as a condition for the permit. The daily maximum permit limit for lead was derived from the '/2 FAV values, established by the EPA, which are designed to protect aquatic biota from acute toxicity effects due to exposure to the toxicant of concern. The effluent monitoring frequency for CBOD, total suspended residue, ammonia, dissolved oxygen, and fecal coliform has been changed from daily to three times per week. Since the facility has a record of good maintenance and operation and has had few compliance issues, it is suggested that the monitoring frequencies be implemented according to the 2B .0500 rules. Conductivity monitoring of the effluent has been inserted as a condition for the permit. Inclusion of conductivity monitoring was implemented according to NCAC T15A 2B .0500 for a Class III facility. The permit application states that the facilities influent is composed of 5 % industrial wastewater, including four industries: Boston Gear, Cal -Maine food, Inc., Murphy House Package Plant, and Almet Lawnlite. Because of the industrial component to the influent wastewaterconductivity monitoring will remain in the permit.

None of the parameters under additional ww characteristics was marked indicating their possible presence in the effluent of the WWTP. Permit Modification Information The only permit modification since the last permit renewal was for insertion of a CBOD limit instead of a BODS limit in July 1995. Wasteload Allocation Information Wasteload allocation conducted 7/22/94. Drainage area = 437 mi2 Average stream flow 460 cfs 7Q10 = 14 cfs Subbasin 03-03-01 Quad: C25SE — Louisburg County: Franklin Receiving stream: Tar River Classification: WS-V NSW Permitted flow = 1.5 MGD IWC = 13% The facility completed an SOC on 7/31/94, upgrading the plant to dual oxidation ditches. In 1994 the facility influent was 95 % domestic and 5% light industrial, having no SIUs. In January of 1996, the Louisburg Water Treatment Plant request permission to increase water withdrawal from the Tar River intake, from 2.0 MGD to 3.0 MGD. The request was denied due to the downstream WWTP and the impact that the reduced 7Q10 flow would have on the ability of the treatment plant to meet permitted limits Speculative limits were issued on January 17, 1995 for an expansion in flow from 1.0 MGD to 1.5 or 2.0 MGD. Correspondence File Review Information 6/97 — NOD issued; the influent and effluent samplers were not properly maintaining temperature at 4 °C. DMR Review 1999: 9/99 — the monthly average for flow exceeded the facilities permitted limit. Through 10/99 the facility is averaging 69.5 % of their permitted flow. 1998: No compliance issues. The facility operated at 57.8% of their permitted flow. 1997: Late with the December chronic toxicity report. The facility operated at 47.9% of their permitted flow. 1996: No compliance issues. The facility operated at 50.0 % of their permitted flow. Basin Plan Review Subbasin 03-03-01 The total area of this subbasin is 664 mi.2 with 3 mi.2 of the total being water. The land cover for the majority of the subbasin is forest/wetland and cultivated crop, with 2% of the subbasin being urban. The discharge point is southeast of the Town of Louisburg, .83 miles upstream of the confluence of Sycamore Creek and the Tar River. The Basin Plan indicates that the Tar River reach between Louisburg and Bunn is impaired for fecal coliform. The suspected source of the contamination is dairy and cattle operations, which are numerous throughout the subbasin. The Basin Plan does not suggest that the Louisburg WWTP in anyway contributes to the fecal coliform problem in this reach. Additionally, the recommendations in the Basin Plan address BMPs for the cattle and dairy operations in the subbasin and does not mention the Louisburg WWTP. General Comments Instream data for dissolved oxygen and fecal coliform, collected by the facility, was evaluated. The instream data for dissolved oxygen showed no discernable impact from the treatment works. Instream fecal similarly showed no discernable impact from the facility. A reasonable potential analysis conducted for lead shows that there is reasonable potential to exceed the water quality criteria for lead. Because dilution is high the allowable concentration for lead is 189.8 ug/1. Therefore, the facility will receive a daily maximum limit equal to Y2 FAV limit.

Alien Mayor LTA/cp (252) 496-4145 • FAX (252) 496-6319 • ncs1087@interpath.com NARRATIVE DESCRIPTION SLUDGE MANAGEMENT PLAN TAR RIVER WATER RECLAMATION PLANT LOUISBURG, NORTH CAROLINA JULY, 1999 The Town of Louisburg owns and operates a 1.37 MGD Grade III wastewater treatment plant. The plant employs a biological nutrient removal activated sludge process. Average daily flow over the past twelve months has been approximately 0.75 MGD. Sludge is wasted from the secondary clarifiers to a gravity thickener at a rate of about 100,000 gallons per week, 0.9% solids. After thickening to about 2.1% solids, the sludge is pumped to an aerobic digester at a rate of about 43,500 gallons per week. The digester has a volume of 600,000 gallons. Given this, the sludge remains in the digester for about 97 days. A second aerobic digester of the same size is currently under construction. As needed, the Town has the capability of feeding caustic to the sludge to raise pH levels. Periodically, depending upon weather conditions and age of digested sludge, the sludge is pumped from the digester to a private hauler truck and moved to the Town's permitted land application sites. Sludge is then land applied. All 503 regulations are met. DRAT NACE FRAM [---DRYING BEDS 1 . T oI— I-- L t_ SLUGDE HOLDING TANK FOR LAND APPLICATION EXIST. SAND DRYING BED EXIST.
