McIntosh, Mayor Town of Burnsville P. O. Box 97 Burnsville, North Carolina 28714 Dear Mayor McIntosh: Charles Wakild, P. E. Director November 28, 2012 Dee Freeman Secretary Subject: Issuance of Permit NCO020290 Town of Burnsville WWTP Class III Facility Yancey County Division of Water Quality (Division) personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. It is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007, or as subsequently amended. This final permit contains the following changes from the previously -issued permit: • The priority pollutant scan requirement was changed from annual to three times, consistent with Division guidance for major municipal wastewater treatment facilities. Please note that this testing requires a low-level sampling method for mercury (EPA Method 1631 E). • A footnote was added to the limit for TRC such that the Division shall consider all effluent TRC values reported below 50 pg/L to be in compliance with the permit. However, you must continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 pg/L. • TRC monitoring was changed from 2/week to 3/week in accordance with requirements for Class III facilities. • Due to the lack of reasonable potential to cause exceedances of water quality standards, monitoring requirements for total lead and for total zinc were eliminated. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Monitoring for these parameters was changed to quarterly in accordance with Division guidelines for action -level parameters. • As a result of an analysis showing that total cadmium in the effluent has a reasonable potential to cause water quality standards exceedances, monitoring for this parameter was changed to monthly and a monthly average limit and a daily maximum limit added. If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable, you have the right to an adjudicatory hearing upon written request within thirty (30) days after receiving this letter. Your request must take the form of a written petition conforming to Chapter 150B of the North Carolina General Statutes, and must be filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such demand is made, this permit remains final and.binding. This permit is not transferable except after notifying the Division of Water Quality. The Division may modify and reissue or revoke this permit. Please note that this permit does not affect your legal obligation to obtain other permits required by the Division of Water Quality, the Division of Land Resources, the Division of Coastal Management, or other federal or local agencies.

Whole effluent toxicity shall be determined by chronic toxicity (Ceriodaphnia) Pass/Fail at 6%. Tests shall be run in March, June, September and December (see condition A (2) for details). 4. The permittee shall perform three effluent pollutant scans during the term of this permit [see condition A (3)]. There shall be no discharge of floating solids or foam visible in other than trace amounts. Permit NCO020290 A (2) CHRONIC TOXICITY PASS/FAIL 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 6%. 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 11 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 TGP36 for the pass/fall results and TMP313 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 Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section 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 Section 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 NCO020290 A (3) EFFLUENT POLLUTANT SCAN The permittee shall perform a total of three (3) effluent pollutant scans for all parameters listed below. One scan must be performed in each of the following years: 2013, 2014, and 2015''!

Average Flow_— - ---------------- (12.) IWC: _� _ 97 cfs 6% Summary • The Town of Burnsville owns and operates a 0.8 MGD activated -sludge wastewater treatment facility. It serves 2,758 people. Average flows from January 2011 to March 2012 were 430,300 GPD, or 54% of capacity. • The facility discharges to the Cane River, a class C-Tr waterbody in the French Broad River Basin. This segment of the receiving stream is not 303(d) listed. • Since the time of the last permit renewal, the Town has added one significant industrial user, Altec Industries. This is a metal coating 1 electroplating operation with a process water intermittent discharge of 12,000 GPD. • Although historically classified as a minor facility, the facility has been reclassified as a major due to the necessity of its pretreatment program. The town was notified of this reclassification in a letter dated September 30, 2010. • During the present permit renewal period, one authorization to construct was issued to this facility. This was for new headworks, the replacement of chlorination and dechlorination facilities, a diffuser upgrade, and the installation of a standby power generator. Compliance Summary DMR Data Review Monthly average DMR data was reviewed for the period January 2008 to April 2012. Due to slugs of toxic influent, the WWTP suffered a series of upsets in spring 2008. This resulted in permit limit exceedances for BOD, TSS, and fecal coliform. Although the Division prepared an SOC to address this situation, the Town retracted its application in April 2010 when the facility began to meet its permit limits on a more consistent basis. Other listed exceedances are three cadmium excursions in 2009 and exceedances of the total lead limit in June 2009, February 2010, and March 2011. NPDES Permit Fact Sheet Town of Burnsville VW TP NCO020290 Flows Data analysis during this review period shows average flows are at 58% capacity while maximum monthly average flows are at 76% capacity. Whole Effluent Toxicity (WET) Testing The facility has passed all of its toxicity tests from January 2008 until the present (June 2012). It is proposed to continue quarterly chronic toxicity pass/fail testing. Instream Data Review The facility is not required to perform instream monitoring. RPA Analysis RPAs were performed for all pollutants of concern. These included cadmium, chromium, copper, cyanide, lead, nickel, silver, and zinc. Data was acquired from discharge monitoring reports (DMRs), annual PPAs, and the Town's pretreatment monitoring plan. Parameters that showed the potential to cause an exceedance of water quality standards were: cadmium, copper and silver. Because the facility has passed all its WET tests, it is recommended that action level parameters copper and silver be monitored quarterly. Monthly monitoring with limits will be proposed for cadmium. Although the facility did not have any sampling hits for total mercury, it used EPA Method 245. The facility will be required to use low-level analysis for mercury for future PPA analyses. Sampling results for all other parameters (chromium, cyanide, lead, nickel, and zinc) did not show reasonable potential to cause exceedances of water quality standards. The draft permit will therefore propose to discontinue monitoring for total lead and for total zinc. Proposed Changes for Permit Renewal • The priority pollutant scan requirement was changed from annual to three times during the current permit term, consistent with Division guidance for major municipal wastewater treatment facilities. • A footnote was added such that the Division shall consider all effluent TRC values reported below 50 pg/L to be in compliance with the permit. However, the permittee must continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 pg/L. • TRC monitoring was changed from 2/week to 3/week in accordance with requirements for Class III facilities. • Monitoring for total lead and total zinc was removed due to lack of reasonable potential for levels of these parameters to cause an exceedance of water quality standards. • Monitoring for total copper and total silver was changed to quarterly in accordance with Division guidelines. • Total cadmium monitoring was changed to monthly with monthly average and daily maximum limits.

We took out lead, since it did not exhibit a reasonable potential to cause an exceedance of water quality standards. However, total cadmium did show this potential, so it is proposed to have limits (see attached draft permit). Please let me know if you need to discuss further... Gil From: Morrison, Sarah Sent: Monday, August 20, 2012 10:34 AM To: Vinzani, Gil Subject: Burnsville NPDES renewal: NCO020290 Gil, I was wondering about the status of issuance of the NPDES renewal for the Town of Burnsville and if you anticipate any changes in the NPDES permit limits for Cd and Pb. I am reviewing the headworks analysis for the Town and will need to send out a letter by tomorrow (8/21). Currently, the headworks is showing an overallocation for both Cd and Pb. The WWTP had the most recent Cd violation in February 2010 and Lead in March 2011 (one in February 2010 prior to that).

Collection System: WQCS00143 (73.8% domestic and 26.2% industrial) There are -.1500 residential, commercial and industrial connections serving a population of 2758. There are - 12.5 miles- of gravity sewers and - .7.5 miles of force main, as follows: 10" gravity-15,606 linear feet 8" gravity - 31,626 linear feet 6" gravity - 52, 001 linear feet 4" gravity - 16,247 linear feet 8" force main - 6,238 linear feet 6" force main-11,468 linear feet 4" force main - 2,216 linear feet There are 4 pump stations. Two of the pump stations have SCADA and one has telemetry. All four pump stations have duplex pumps and are checked 7 days a week. Main PIS has 50 HP dry pit pumps Altec PIS has 25HP submersible pumps Baker's Creek P1S has 20 HP dry pit pumps Mayland PIS has 10 HP submersible pumps. Cleaning: During 2010, - 3300 to 3400 feet of sewers were cleaned. GIS Mapping: GIS mapping work is currently being performed by High Country Engineering to locate and map all of the collection system lines and manholes. Infiltration & Inflow Improvements: Annual Average Flows: January 2004 through May 2009 = 0.317 MGD (47.7% of permitted flow). During that period, rainfall events exceeding 1 inch, increased the flow to the WWTP to an average of 723,600 gpd. 1 &•1 work, since that time, has continued to reduce peak flow conditions. McGill & Associates' are implementing an I & I Remediation Project which is scheduled to go out to bids during,the spring 1 summer of 2011. Relocation of utilities: All of the utilities along the US Hwy 19 E corridor will be relocated as a result of the ongoing road widening project. This project will be a utilities betterment (upgrade) and will increase the size of the existing water mains. Pretreatment: There is one significant industrial user (SIU), Altec Industries Inc., which is a Construction Machinery and Equipment Manufacturer. Altec applies coatings, such as, zinc phosphate (corrosion inhibitor) to truck beds in preparation for painting. Sludge Management: WQ0002834 Class A Distribution and Marketing of Residuals (Composted Sludge) The sludge management and solids handling facilties consist of: two aerobic digesters; 616 sq ft sludge dewatering building; 2.8 liter Roediger sludge belt filter press; sludge composting facility (with 50 x 60 ft concrete paved area for storage, mixing and digestion) for the (surface disposal) distribution & marketing of Class A residuals (permit # W00002834). The belt filter press sludge dewatering operations are divided into three general stages: initial de -watering, which makes the sludge pulp; pressing or medium pressure filtration, which conditions the sludge for high pressure filtration quality; and high pressure filtration, which raises the dry solids content in the sludge cake to the optimum. The process begins as the sludge enters the press, where it is mixed with a chemical which causes flocculation of the sludge. The sludge then enters the gravity drainage zone, where a large rotating drum agitates the floc.and drains approximately 70% of the free water. The resulting capture rate can be as high as 99%. Pressure is first applied in a low pressure wedge zone, which begins squeezing remaining water out of the sludge. Further de -watering occurs in the medium pressure zone, where two large perforated drums of decreasing size apply the pressure. Rollers perform the final de -watering in the high pressure zone. The sludge cake (filtered solids) then exits the machine. The belting on a belt filter press must be continuously washed with clear water to keep it from blinding (clogging up). This is accomplished by water spray bars placed above returning belt. The final sludge cake product is mixed with wood in chips and stored for further treatment and digestion. Finally, the finished product is made available for distribution to the public for use as a soil amendment. Authorization to Construct issued 11-21-2000 for the installation of a new sludge belt filter press. McGill & Associates' PE certification was signed on 4-30-2002, indicating the completion of this project. A to C: Authorization to Construct issued 10-11-1990 for a 10,900 gal chlorine contact chamber (for the 0.5 MGD plant) and a 6480 gal chlorine contact chamber (for the 0.3 MGD plant) and a 280 gal dechlorination tank with diffused sulfur dioxide injection.
