Drawer 192 Boone, North Carolina 286077 Alan W. Klimek, P.E. Director Division of Water Quality Subject: NPDES Permit Issuance NPDES Permit NCO020621 Jimmy Smith WWTP Watauga County Dear Mr. Miller: 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. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended). The permit authorizes the Town of Boone to discharge up to 4.82 MGD of treated wastewater from the Jimmy Smith Wastewater Treatment Plant to the South Fork New River, a class C+ water in the New River Basin. The + symbol identifies waters that are subject to a special management strategy for the Outstanding Resource Waters (ORW) to protect downstream waters designated as ORW. The permit includes discharge limitations /or monitoring for flow, biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia, fecal coliform bacteria, pH, copper, zinc and chronic toxicity. The following modifications were made to the permit: • The addition of weekly average limits for ammonia. The summer limit will be 6.0 mg/1 and the winter limit will be 12.0 mg/L. The weekly average requirements for ammonia are necessary to comply with federal regulations. The deletion of the total residual chlorine limit based on the facility's use of ultraviolet disinfection for treatment of the effluent. A permit condition (A.(4)) has been added that will apply a total residual chlorine limit of 28 ug/l' if the facility should use chlorine for effluent disinfection. The correction of the monthly average total suspended solids (TSS) limit from 10 mg/1 to 20 mg/1. The previous TSS limit of 10 mg/1 was given because of the incorrect assumption of a trout designation on this segment of the South Fork New River in addition to the ORW classification. It has been verified that the correct stream classification is C+ and the TSS limit of 20 mg/1 should be given. The weekly average TSS limit will be changed to 30 mg/1 (which is the monthly average limit of 20 mg/1 multiplied by 1.5).

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 44%. The permit holder shall perform at a minimum, guarterlu monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase Il 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 THP313 for the Chronic Value.

I came across a question about whether their receiving stream is C-ORW like their permit says, or C-Trout like they used to be, or C-Trout and ORW both like the limits seem to imply, or what. The RPA had used one-half of the Class C WQS for cadmium, not the trout WQS for cadmium, but the permit assigned a 10 mg/l TSS like the 02B .0225 strategy says to use for trout streams, not the 20 mg/l it says for non -trout. 1 went to Jackie for help and she said we needed Alridge to review the maps and make an official classification determination. He confirmed it is C+, where the + means apply the strategy in 02B .0225 to protect the downstream designation of ORW. He also said it is not a trout stream. So I will tell Boone to use one-half of the Class C WQS. 1 will not mention the 10 versus 20 mg/l TSS to Boone, but let you do whatever you need to do on that at the permit renewal which is scheduled for early next year. I will put a copy of this email and the sheets with my notes of my conversation with Alridge in the Boone NPDES file for your reference.

The facility serves approximately 14000 persons in the Town of Boone and surrounding area. The facility is currently at about 50% of design capacity and discharges a high quality effluent. Existing limits for protection of water quality standards are 5/2/6 and 10/4/6.. The Boone WWTP has a full Long Term Monitoring Program (LTMP) with its Pretreatment program and handles waste flow from one (1) significant industrial user (SIU). The current permit contains limits/monitoring requirements for the following metals/toxics: mercury, cyanide, selenium, copper, silver, and zinc. It is recommended that the Town continue to implement the pretreatment program during the next permit cycle. Receiving Stream/Instream Monitoring Review This segment of the South Fork New River has a stream classification of C+. The + symbol identifies waters that are subject to a special management strategy for the Outstanding Resource Waters (ORW) for the protection of a downstream waters designated as ORW. (The downstream water is the New River). The South Fork New River is not listed on the NC Impaired Streams List (2006). Instream monitoring is not required of this facility. Fact Shed NPDES NC002062I Rt-m-wal Wtle I Compliance Review The plant has a very good compliance record. Despite the stringent limits for BODS, NH3, TSS, and metals, the Boone WWTP has had very few permit limit violations. The facility consistently discharges levels of BODS of <2 mg/l, NH3 <1 mg/l, and TSS < 0.1 mg/l. The most recent permit violation was in 2003 for cyanide however no other violations of any parameters have occurred in nearly three years. Note: Weekly average limits for NH3 will be added to the permit per federal regulations. Note2: The TSS limit of 10 mg/l previously given for ORW waters with a trout classification will be corrected and modified to 20 mg/1 for nontrout ORW waters. Toxicity Testing Existing: Chronic Quarterly Pass/Fail at 44% - testing required during the months of March June September and December. Facility has had an excellent record of compliance with the toxicity test. Boone has passed every tox test from March 2002 through June 2006 Recommendation: Renewal of existing Chronic P/F toxicity test @ 44% Reasonable Potential Analysis (RPA): A reasonable potential analysis (RPA) was performed for the following limited or monitored parameters: • Silver • Mercury • Zinc • Copper • Cyanide • Selenium The ORW strategy requires that water quality standards equal to one-half of the value be protected in the streams. Effluent data from January 2004 through Apfil 2006 was evaluated in the RPA using values equal to one half of the water quality standard. Results indicated that no reasonable potential to exceed the water quality standard exists for the following: • Silver • Mercury • Cyanide • Selenium Based on the RPA results, limits for cyanide, mercury and selenium will be dropped from the permit, in addition to silver monitoring which will also be dropped from the permit. These four parameters will be monitored on a quarterly basis in the pretreatment program's LTMP. Fact Sheet wror,S nICo020s21 Rvnewat Page 2 Results of the RPA indicated that effluent monitoring for the following two parameters will remain in the permit based on reasonable potential to exceed the action level standards: • Copper • Zinc A review of priority pollutant analysis (PPA) data that was submitted indicated that most parameters recorded values below the method detection level and therefore was assumed to have no reasonable potential to exceed the water quality standards. A value for bis (2-ethylhexyl) phthalate was considered to be a laboratory contaminant and was not evaluated in the RPA. SUMMARY OF PROPOSED CHANGES • Addition of summer and winter weekly average limits of 6 mg/1 and 12 mg/l, respectively, for ammonia (NH3-N) per requirement of federal regulations. • The deletion of TRC limit based on use of ultraviolet disinfection for effluent treatment. A condition was added to permit that states if chlorine ever used as backup disinfection, a TRC limit of 28 ug/l will become effective. • The monthly average TSS limit was corrected to 20 mg/l as required for discharge to a non -trout ORW water. Stream classification has previously been indicated as C Tr and a more stringent limit of 10 mg/l was given. The correct classification of C+ has been verified and the TSS limit should be modified. • Effluent limits for cyanide, mercury, and selenium were dropped from the permit based on results of the RPA. There is no reasonable potential to exceed the water quality standard. Quarterly monitoring for the three parameters will continue in the pretreatment program's LTMP. • Effluent monitoring for silver was dropped from the permit based on results of the RPA. There is no reasonable potential to exceed the water quality action level standard. Quarterly monitoring for silver will continue in the pretreatment program's LTMP. • The addition of an annual effluent pollutant scan, per requirement for municipal application data requirement.

Enclosed are the completed, signed application forms and the required location map, facility line drawing, and narrative description of the treatment process and sludge management plan, We also request that we be allowed to reduce our mercury monitoring requirement from once a week to quarterly in conjunction with our Long Term Monitoring , due to the fact that all of our samples with the new sampling method have been below the North Carolina water quality standard. There have been no changes to the plant process since issuance of the last permit. If you have any questions about this package, please feel free to call me at the plant at (828) 262- 4580. Sinc ely, 00 qRiiller Director of Public Utilities P.O. DRAWER 192 • BOONE, NORTH CAROLINA 28607 Potential Facility Changes (5-year) Due to the recent construction improvements for which the last NPDES permit was issued, we do not anticipate any major projects for expansion or repairs at the plant for the next five years. Schematic of Wastewater Flow Included in this package are the following drawings for describing the plant flow path: 1) Site plan 2) Piping plan 3) Process schematic 4) Hydraulic profile The site plan drawing includes arrows for indicating the flow path through the facility. Location Map The USGS Boone Quadrangle topographic map is attached showing the location of the plant. Narrative Description of Sludge Management Plan The plant removes 3,500-5,000 Ibs of solids from the influent treatment process daily in the form of waste activated sludge with total solids of 6,000-8,500 mg/L. This material is aerobically digested for 5-7 days, then de -watered on an Eimco 2-meter belt press to a solids level of 15%- 18%. The cake sludge is then dried to 88%-92% in a Stord TST-40 thermal drier. The drier is heated by steam produced by a propane -fired steam generator manufactured by Clayton Industries. Biosolids production is approximately 600 lbs. per hour or 500 tons per year. With the above treatment, the product meets and exceeds Vector Attraction Reduction method 7 (% solids > 75%) and Alternative 5, Item g of the Processes to Further Reduce Pathogens (PFRP) for Class A biosolids. The material is sold in bulk to the public for use as fertilizer on pastures, meadows, Christmas trees, and in landscaping. The product is registered with North Carolina Department of Agriculture with a guaranteed N-P-K analysis of 5-5-0. An information sheet distributed to recipients of Class A residuals is included in this application. The plant has a backup Class B residuals permit that would be used if the Class A system was unavailable for an extended period. In the past three years, no Class B material has been produced, and we do not anticipate any processing in the future. Item 6: Facility Description Present Operating Status: The plant is a tertiary treatment facility with a design capacity of 4.82 MGD. Average daily volume for the period from March 1999 to April 2000 was 2.39 MGD. Vulcan automatic mechanical bar screens remove coarse screenings, then convey the water to an influent pump station housing three 5500 gpm Flyght submersible pumps. Water is pumped to the highest elevation in the plant to a GH Systems aerated grit/grease removal unit where grit settles in a trough supplied with coarse air and grease is skimmed from a parallel trough to a grease trap. The grit, grease, and bar screenings are hauled to a landfill in Caldwell County for disposal. Wastewater then flows to one of two oxidation ditches, each with a capacity of 2.4 MG. Hoffman centrifugal blowers supply air through 2200 fine bubble diffusers anchored to the basin floor. The basins are divided into four quadrants, and vertical mixing is achieved by coarse air channels between quadrants that lift the water from the bottom of one section to the top of the next chamber. This is a relatively new design that prevents dead zones and laminar flow in basins too deep for surface mounted brush aerators. The ditches are capable of complete nitrification due to their large sire and zonation. Ditch effluent enters two circular 0.9 MG clarifiers with lift piping and centerwell draft tubes for return of activated sludge via Crown centrifugal pumps. Pinch valves regulated by inline magnetic flow meters control the return and waste pumping rates. Clarifier effluent suspended solids range from 4-8 mg/L. Clarifier effluent undergoes tertiary treatment through four Leopold deep -bed sand filters, where effluent suspended solids are further reduced to 0.3-1.5 mg/L. Disinfection is accomplished by a Trojan UV4000 ultraviolet system featuring two separately powered, self-cleaning, flow paced banks of 16 lamps (2800 watts each). In the final step, the effluent flows down a cascade aeration structure for further oxygenation before discharge to the South Fork of the New River. Solids are wasted to two aerobic digesters holding 430,000 gallons each. They are de -watered after 3-5 days of digestion by an Eimco 2-meter belt press to a 15%-18% cake, then dried to 86%-92% solids in an Atlas-Stord'rST-40 thermal drier. A steam generator powered by propane heats the drier. The final biosolids product is a high quality Class A fertilizer containing approximately 6% nitrogen, and 5% phosphorous. The material is sold to the public for use on Christmas trees, pasture and meadowland, and nursery crops. Annual production is 500-550 tons.
