Baker, P.E. Director of Public Works Town of Waynesville PO Box C-100 Waynesville, North Carolina 28786. , Subject: NPDES Permit Issuance Permit No. NCO025321 Waynesville WWTP Haywood County Dear Mr. Baker: Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit 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. EnvironmentalProtection Agency dated May 9, 1994 (or as subsequently amended). The permit authorizes the Town of Waynesville to discharge up to 6.0 MGD of treated wastewater from the Waynesville WWTP to, the Pigeon River, a class C water in the French Broad River Basin. The permit includes discharge limitations /or monitoring for flow, biochemical oxygen demand (BOD), total suspended solids USS), fecal coliform bacteria, dissolved oxygen, total residual chlorine, cyanide, copper, zinc, and chronic toxicity.. , The following modifications have been made in this permit: The daily maximum limit for cyanide has been dropped from the permit based on an analysis of submitted effluent monitoring data, that indicated there is no reasonable potential to exceed the water quality standard. However, it is . recommended that twice per month monitoring for cyanide remain in the permit for protection of the acute allowable concentration. The effluent limits for cadmium, mercury and nickel, have been deleted from the permit based on an analysis of submitted effluent monitoring data. . It is recommended that these parameters continue to be monitored quarterly in the pretreatment program's Long Term Monitoring Program (LTMP). N. C.

The data indicates that the facility is now averaging a percent removal rate of nearly 95% for both parameters. The previous variance for the removal rate does not appear to be needed any longer. Please note the change in A (1), footnote 2. • The instream monitoring sites in the permit have been modified to reflect the actual sites where the Town of Waynesville is collecting instream data. The upstream site is River Mile 55.5 and the downstream site is River Mile 53.5 • A total residual chlorine limit of 28 ug/1 has been added to reflect the Division's current policy for protection against chlorine toxicity instream. If a method different than chlorination/dechlorination is used, the total residual chlorine lirnit will not be applicable. There is an eighteen (18) month compliance schedule to meet this limit. See Special Condition A (4.) • An annual effluent pollutant scan has been added to fulfill EPA's application requirement for major municipal wastewater treatment facilities. Special Condition A. (3.) of this permit details this requirement. If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter.

CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 9%. The permit holder shall perform at a minimum, quarter iu 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 February, 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 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: .

The current permitted design flow is 6.0-MGD. The plant averaged 4.07 MGD in 2004 which is 67% of capacity. The plant is serving the Town of Waynesville, Lake Junaluska Assembly, the Junaluska Sanitary District, and the Town of Clyde. Waynesville has a full Long Term Monitoring Plan (LTMP) with the Pretreatment Unit and accepts wastewater from one Categorical Industrial Users (CIU). Facility has had a previous permit variance for 80% removal of BOD5 and TSS. Upon review of the past two years of influent and effluent data for Waynesville, it has been determined that the 80% removal condition is no longer needed. The % removal for BOD5 and TSS will return to 85%. removal. RECEIVING STREAM The receiving stream is the Pigeon River in the French Broad River Basin and is classified C. This segment of the Pigeon River is not listed on the 303(d) list for Impaired Streams. A segment of the Pigeon River above the Waynesville discharge is on the 2004 NC Impaired Streams List for biological integrity with stressors not identified. NOTE: Also Richland Creek, is on the impaired streams list for impaired biological integrity and potential sources as agriculture and urban runoff/storm sewers. The Town of Waynesville is encouraged to check damaged sewer lines for contribution to the problems of Richland Creek. COMPLIANCE SUMMARY/CORRESPONDENCE REVIEW The facility received a notice of violation (NOV) in May 2003 for exceeding the TSS weekly average of 45 mg/1 . The facility had been under an SOC for TSS in 1997-1998. The facility received a notice of deficiency (NOD) for a late toxicity monitoring report in February 2003. NPDES NC00253' 1 R,neNkal P�gr 1 A NOV and civil penalty issued for fecal coliform violations in August 2004. Compliance inspection reports in 2003 - 2005 were satisfactory. The facility received a notice of violation (NOV) in Nov. 2004 for exceeding the TSS weekly average of 45 mg/l . TOXICITY TESTING Current Requirements. Chronic Toxicity at 9%: Feb May Aug Nov A review of submitted chronic Ceriodaphnia toxicity tests shows that the facility has passed all sixteen tests since February 2002. Recommendation: Renewal of the existing chronic toxicity test @ 9% INSTREAM MONITORING Current Upstream site: NCSR 1108 Current Downstream sites 1) NCSR 2424 2) NCSR 564 Town is taking samples upstream at river mile 55.5 and downstream at river mile 53. Believe the instream monitoring site change in 2002 was an error. There is are no highway crossings on the Pigeon River that correspond with these numbers. Recommendation: Will change the instream monitoring sites to River Mile 55.5 upstream and 53.5 downstream. A review of instream monitoring data for the past three years, shows there are no problems upstream or downstream of the Waynesville plant with DO or temperature. Most downstream DO values average between 8 - 9mg/l. REASONABLE POTENTIAL ANALYSIS/RESULTS: Analysis was conducted using discharge monitoring reports from January 2004 through December 2005. The parameters that were analyzed were arsenic, cadmium, chromium, copper, cyanide, lead, mercury, molybdenum, nickel, selenium, and zinc. See attached RPA results. • The analysis of the following parameters did not show reasonable potential to exceed either the acute or the chronic allowable concentrations. The maximum predicted concentrations were less than the allowable and therefore no limit or monitoring will be required. These parameters will be monitored quarterly in the Waynesville's Long Term Monitoring Plan (LTMP): Arsenic, cadmium, chromium, lead, mercury, molybdenum, nickel and selenium. • The analysis of the following parameter did not show reasonable potential to exceed either the acute or the chronic allowable concentrations. However, the maximum predicted concentration was very close to the acute allowable concentration (20.6 ug/1 versus 22 ug/l acute allowable). Actual reported value was 16 ug/1 in April 2005. Therefore, BPJ will recommend that existing limit for cyanide be dropped and 2/month monitoring will be required: Cyanide • The analysis of the following parameters did show reasonable potential to exceed the acute and/or the chronic allowable for the NC action level standard. Per NCDWQ procedure, no limit will be recommended due to there being no chronic toxicity problems with the facility. It is recommended that 2/month monitoring be continued in the permit for these parameters: Copper and Zinc SUMMARY OF PROPOSED CHANGES • The addition of a total residual chlorine limit of 28 ug/l based on Division procedure of dischargers into NC waters. Facility will be given 18 months to comply with limit. • Recommend the deletion of the 80% removal condition for BOD5 and TSS. A review of influent and effluent data for the past two years indicates that the facility is meeting 95% removal for these two parameters. • The addition of an annual effluent pollutant scan based on EPA requirements for municipal dischargers with greater than 1.0 MGD design flow.

The sites were changed in the 2002 permit renewal but no rationale was round for the change. The Town has continued to sample at the river mile sites and it ig recommended that those sites it be previous numbered continued. • Effluent limits for Cadmium. Mercury, and Nickel will be dropped due to no reasonable potential to exceed allowable. Will be monitored quarterly in the LTMP.

Blue Ridge Paper Products (BRPP) had improved its manufacturing process to eliminate the release of the chemical dioxin, a by-product of the paper making process. DWQ will participate in a Joint Watershed Advisory Group and continue to monitor the river as additional improvements are made. Local- initiatives are needed to address the nonpoint source impacts to the river from the towns of Canton and Clyde and outlying nonurban areas. Current Status Pigeon River. [AU# 5-(1), 5-(6.5) and 5-(7)a], from source to 0.15 miles downstream of West Park Street in Canton (6.1 miles), is Supporting due to a Good -Fair bioclassification at site B-1. This site has been sampled 13 times since 1983, and the bioclassification has varied between Good -Fair and Excellent due to year-to-year differences in flow and habitat. Much of the nearby land is used for agricultural purposes, but an increasing number of vacation homes are being built in the upper reaches of the watershed. Chapter 5 - French Broad River Subbasin 04-03-05 64 Pigeon River [AU# 5-(7)b], from 0.15 miles downstream of West Park Street in Canton to SR 1642 (Main Street in Clyde) (6.4 miles), is currently Impaired in the aquatic life category due to a Poor bioclassification at site B-4. The sampling site is located approximately 5 miles downstream of Blue Ridge Paper Products, Inc. (BRPP) and has been sampled 12 times since 1984. Historically, this site has received Fair and Poor bioclassifications, but improvements in BRPP's processes were evident in samples collected in 1992 (improvement from Poor to Fair) and 1997 (improvement from Fair to Good -Fair). In 2002, however, the bioclassification decreased to Poor. This decrease is likely associated with drought conditions during the time of sampling. Pools were absent; riffles were minimal, and aquatic weeds were abundant. These factors, along with low flow conditions and the subsequent lack of dilution of the BRPP effluent likely impacted the benthic community. Conductivity was also high at the time of sampling. A review of data from the DWQ ambient monitoring station (A-16) showed that the mean conductivity has been steadily increasing at the site since 1998. This site also receives nonpoint urban and stormwater runoff from the towns of Canton and Clyde. This nonpoint runoff could also impact the benthic community in this stretch of the river. In addition to DWQ sampling, EA Engineering, Science and Technology, Inc. (EA) collected fish and macroinvertebrate samples along the Pigeon River and three major tributaries (Jonathan Creek, Fines Creek and Richland Creek) in the summer of 2000. The study was prepared for BRPP following NCDENR protocols and examined the overall fish and macroinvertebrate communities in the watershed. The EA survey was compared to a 1995 survey and found that: 1) the number of smallmouth bass had increased 10 fold; 2) darters were found where they were absent in 1995; and 3) species richness had improved downstream of the BRPP discharge. Macroinvertebrate communities ranged from Fair, Good -Fair, and Good with a Good bioclassification on both Jonathan Creek and Fines Creek and a Fair bioclassification on Richland Creek (EA, May 2001). DWQ sampling and use .support ratings for Jonathan Creek, Fines Creek and Richland Creek are presented below. A Settlement Agreement was reached in 1997 on a modified color variance and NPDES permit for BRPP. The. following agencies participated in the agreement: the U.S. Environmental Protection Agency (EPA); the states of North Carolina and Tennessee; Cocke County and the City of Newport, TN; the Tennessee Environmental Council; the American Canoe Association; and BRPP. The intent of the agreement was to address the Pigeon River color issue without litigation. The goal was to reach an annual average color loading of 48,000-52,000 lbs/day by May 1, 2001. This goal was met. All of the BMP projects as required in the agreement are complete and operational. Additional color reduction measures were completed and others are ongoing. Contingency plans for low flow periods were in place and operational. Pursuant to the agreement, North Carolina and Tennessee were required to establish a Joint Watershed Advisory Group to foster joint planning and public input on decisions affecting the Pigeon River. This group has been meeting since 2000. BRPP has also been working with a Community Advisory Committee composed of community leaders in Haywood County (North Carolina), Cocke County (Tennessee), and the State of North Carolina. Overall, the water quality in the Pigeon River has, improved dramatically over the last 15 years. Annual fish tissue monitoring for dioxin in the Pigeon River is conducted by BRPP and Carolina Power and Light Company (CP&L). This monitoring is required as part of the BRPP discharge Chapter 5 —French Broad River Subbasin 04-03-05 65 permit issued by DWQ and as a condition of the Federal Energy Regulatory Commission (FERC) license for CP&L. In the past, there has been a limited -consumption advisory for common carp in effect for the Pigeon River from the Town of Canton to the North Carolina - Tennessee state line (approximately 26 miles, including Waterville Lake). In 2001, the NC Department of Health and Human Services (NCDHHS) revised this advisory due to declining dioxin concentrations in fish. The advisory was removed from common carp caught in the river, but remains in effect for Waterville (Walters) Lake. NCDHHS suggests that women of childbearing age and children under the age of 15 avoid eating carp caught from the lake. For all others, consumption of carp should be limited to no more than one meal per month. Swimming, boating and other recreational activities are not affected by this advisory. Visit the NCDHHS website for more information at www.epi.state.nc.us/epi/fish. In addition, the State of Tennessee had a historical limited -consumption advisory for common carp, catfish species, and redbreast sunfish in effect for the Pigeon River within the State of Tennessee downstream to the confluence with the French Broad River. Due to monitoring conducted from 1996 to 2002, the Tennessee Department of Environment and Conservation (TDEC), Division of Water Pollution Control (DWPC) recommended that the Fish Consumption Advisory be removed (TDEC-DWPC, October 2002). This advisory has been lifted; however, the Pigeon River (5 miles) remains on the Tennessee 303(d) list for color. 2005 Recommendations DWQ will continue to monitor the Pigeon River to study the sources and impact of increasing conductivity. DWQ will continue to work closely with BRPP to minimize the impact of its discharge and continue its involvement in the Joint Watershed Advisory Group. Additional provisions during times of drought should be reviewed and perhaps revised in the next permit cycle for BRPP to protect water quality in Pigeon River. In addition, DWQ recommends erosion and sedimentation control measures be taken in areas of the watershed that are under development. Water Quality Initiatives Haywood Waterways Association (HWA) is a nonprofit organization dedicated to maintaining and improving the water quality of the Pigeon River. It focuses on reducing nonpoint source pollution by offering education and outreach programs and working through a variety of voluntary initiatives, concentrating on individual landowners. HWA partnered with TVA to conduct a nonpoint source inventory (IPSI) of Haywood County using low -elevation infrared photography and interpretation. TVA digitized multiple layers of GIS information obtained from the photo interpretation. Nonpoint sources such as septic systems, illegal dumps sites, eroding roads and streambanks, pastureland and animal access to streams were identified. This information was used by TVA to apply a nutrient loading model to calculate a nutrient budget for the Haywood County portion of the Pigeon River watershed. HWA and the Haywood County Soil and Water Conservation District (SWCD) then used the TVA model and IPSI data to develop and implement strategies for water quality improvements. A Watershed Action Plan (HWA, 2002) was written detailing the inventory results and 19 strategies were recommended to improve water quality in the watershed. Using the IPSI data, TVA and HWA were able to identify the most heavily impacted subwatersheds, identify and rank the nonpoint sources, and identify landowners where the nonpoint sources were located. EPA 319 and Clean Water Management Trust Fund (CWMTF) Chapter 5 — French Broad River Subbasin 04-03-05 66 grants were secured for sediment and water quality monitoring, educational publications, and a variety of best management practices (BMPs) projects on lands with participating landowners. BMP projects include: fencing livestock from streams; improving high -use areas and stock trails adjacent to the streams; streambank stabilization; improving riparian buffers; and a stormwater management project in a rural subdivision. Financial incentives in the form of reduced cost or no -cost BMP work are offered to the landowners in return for long-term management agreements or conservation easements.

Support methodology changed since the 303(d) listing for Waterville Lake, and based on previous results, the lake is Supporting for its uses. Despite this change, however, a fish advisory remains in effect for catfish and carp, and the lake remains on the 303(d) list of Impaired waters. Currp.nt ,1tRtuv Waterville (Walters) Lake, from White Oak Road to Waterville Reservoir Dam (773.1 acres), is currently Not Rated in the aquatic life category. Waterville Lake receives runoff from urban and agricultural areas, which includes the Richland Creek, Jonathans Creek and Fines Creek watersheds. Samples collected from Waterville Lake showed evidence of eutrophication. Parameters of concern include chlorophyll a, elevated surface dissolved oxygen, and pH. There was also increased algae growth, specifically blue-green algae in the reservoir, during the summer of 2002. The elevated levels of chlorophyll a, conductivity and dissolved gasses may be attributed to drought conditions during the time of sampling. Low flow combined with limited dilution of upstream discharge effluents and nonpoint sources may also be contributing to the eutrophic conditions. Waterville Lake remains under a fish consumption advisory for common carp. NCDHHS revised the advisory in 2001 and suggests that women of childbearing age and children under the age of 15 avoid eating carp caught from the lake. For all others, consumption of carp should be limited to no more than one meal per month. Swimming, boating and other recreational activities are not affected by this advisory. Sampling by DWQ and CP&L shows that dioxin concentrations in all species of fish collected from the lake have decreased since the early 1990s. Dioxin levels in common carp, however, remain above the North Carolina limit. Waterville Lake is on the state's 303(d) list of Impaired waters due to the fish consumption advisory. See Section 5.3.1 for more information. 2005 Recommendations DWQ will continue to monitor water quality in Waterville (Walters) Lake. In addition, DWQ will work with Progress Energy (CP&L) and BRPP to develop a Quality Assurance and Project Plan (QAPP) so that their data can be used by DWQ in determining use support ratings in the future.

Weaver, Jr. NCDENR/DWQ/Point Source Branch 1617 Mail Service Center Raleigh, NC 27699-1617 Re: Renewal Application Permit NC 0025321 Waynesville WWTP Dear Mr. Weaver: � 6- � IL JUL 2 The Town of Waynesville respectfully requests renewal of permit NC 0023521 for the Waynesville WWTP. Submitted in triplicate are completed EPA Form 2A application and narrative of the sludge management plan for the facility. Since the issuance of the NPDES permit renewal in 2002 there have been no significant changes to the facility, The sludge belt filter press was replaced in 2002 with an Enviroquip 1.7m series. There was no change to the unit processes; just equipment replacement with an upgrade in size and performance. Do not hesitate to contact me at 828-4564410 if questions or comments arise. Sincerely, Ar, erick L. Ba. Director of Public Works cc: Lee Galloway, Town Manager David Smith, WWTP Superintendent POE 100. 16 SOUTH MAIN ST., WAYNESVILLE, NC 28786 • PHONE (828) 456-3515 • FAX (828) 456-2000 Narrative Description of The Town Of Waynesville Wastewater Treatment Plant Sludge Management The Town Of Waynesville Wastewater Treatment Plant Generates both Primary'sludge with primary clarifiers and Waste Activated sludge from the secondary Activated Sludge process at the Wastewater Treatment Plant. The two Settled sludges are gravity thickened in Primary and Secondary Gravity Sludge Thickeners. The Gravity thickened sludges are pumped to an Anaerobic Digester for further Volatile solids and pathogen reduction. The digested sludge is then dewatered with a 1.5 meter belt press. The dewatered sludge is blended with Lime Kiln dust and Agricultural Lime to achieve the required Vector Attraction Reduction requirements and is Heat pasteurized to 158 degrees or greater for Pathogen reduction requirements. The lime Stabilization and Heat Pasteurization equipment used is RDP Technologies Thermoblender and 30 minute detention time Pasteurization Vessel. All biosolids produced are stored in a covered Building onsite .The Biosolid product is distributed to the public free of charge.
