Sullins Dee Freeman Governor Director Secretary July 27, 2011 Mr. Tim Church, Water Resources Director Town of Jefferson P.O. Box 97 Jefferson, North Carolina 28640 Subject: NPDES Permit Issuance Permit NC0021709 Jefferson WWTP Facility Class I j Ashe County Dear Mr. Church: 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 October 15, 2007 (or as subsequently amended). The final permit authorizes the Town of Jefferson to discharge wastewater from the Jefferson WWTP to Naked Creek, a class C+ water in the New River Basin. The supplemental "+" symbol on the classification indicates that N'aked Creek is subject to a special management strategy in the Outstanding Resource Waters rule to protect the downstream South Fork New River. The final permit includes discharge limitations/or monitoring requirements for flow, BOD5, ammonia nitrogen, total suspended solids (TSS), dissolved oxygen, total residual chlorine, fecal coliform, copper, zinc, cyanide, lead, cadmium, mercury, and several other parameters. The receiving stream, Naked Creek, is also listed as an impaired waterbody on the North Carolina 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required. The following procedure has been implemented by DWQ: Total residual chlorine (TRC) compliance level changed to 50 ug/1 Effective March 1, 2008, the Division received EPA approval to allow a 50ug/1 TRC compliance level. This change is due to analytical difficulties with TRC measurements. Facilities will still be required to report actual results on their monthly discharge monitoring report (DMR) submittals, but for compliance purposes, all TRC values below 50 ug/1 will be treated as zero. A footnote regarding this change has been added to the effluent limitations page in the permit and was included based on the facility's chlorination system. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Because of North Carolina's statewide mercury impairment of all streams, the removal of a mercury limit from an existing permit is not allowed unless a Total Maximum Daily Load (TMDL) to address the impairment has been developed. Therefore, monthly average and daily maximum limits of 40 ng/1 for mercury are in the final permit and will be monitored quarterly. Correspondence from EPA with their rationale and explanation on this matter is being forwarded to the City of Jefferson. These modifications listed in the draft permit, remain in the final permit: • A monthly average limit of 3.4 ug/1 and a daily maximum limit of 22.3 ug/1 for cadmium have been added to the permit and will be sampled monthly. Results of a reasonable potential analysis on submitted data indicated there was reasonable potential to exceed the water quality standard instream. • A monthly average limit of 8.4 ug/1 and a daily maximum limit of 32.8 ug/1 for cyanide have been added to the permit and will be sampled monthly. Results of a reasonable potential analysis on submitted data indicated there was reasonable potential to exceed the water quality standard instream. • Total lead will continue to be limited in the permit, and has been modified to a monthly average of 42.1 ug/1 and a daily maximum of 50.3 ug/1..Lead will be sampled monthly. Results of a reasonable potential analysis on submitted data indicated there was reasonable potential to exceed the water quality standard instream. • Monitoring for copper and zinc will remain in the permit based on the results of the reasonable potential analyses, which indicated potential to exceed the water quality action level standard instream. Copper and zinc will now be monitored quarterly in conjunction with the whole effluent toxicity test. • Monitoring for total silver has been deleted from the permit. Results of a reasonable potential analysis on submitted data indicated there was no reasonable potential to exceed the water quality standard in the receiving stream. Silver should continue to be monitored during the pretreatment program plan. • Please note that there have been minor language changes and the addition of a new paragraph regarding data submittal in special condition A.2. Chronic Toxicity permit limit. (The new paragraph is located second from the end of the condition). 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. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be final and binding. Letter to Mr. Church Please take notice that this permit is not transferable. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits, which may be required by the Division of Water Quality, or permits required by the Division of Land Resources, Coastal Area Management Act, or any other Federal or Local governmental permits may be required.

The plant has completed an expansion and upgrade from 0.3 MGD to 0.6 MGD. The facility discharges to Naked Creek, which is classified as a C+ waters in the New River Basin. Because of the supplemental "+" symbol on the classification, Naked Creek is subject to a special management strategy in 15A NCAC 2B .0225, the Outstanding Resource Waters (ORW) rule to protect the downstream waters South Fork New and New Rivers designated ORW area. The stream is listed on the 2010 North Carolina impaired stream 303(d) list for degraded ecological/biological integrity within the fish community. The permit will continue to require the City to implement its pretreatment program. Jefferson has a pretreatment program with a short term monitoring plan, because it has a permitted flow of less than 2 MGD and/or less than four (4) significant industrial users (SICs). Significant industrial users include American Emergency Vehicles and Gates Rubber Company. REASONABLE POTENTIAL ANALYSIS: The following parameters are monitored through the existing permit: Cd, CN, Cu, Pb, Zn, Hg, Ag. The following parameters are monitored through the modified pretreatment program with short term monitoring program (STMP): As, Cd, Cr, Cu, CN, Pb, Hg, Mo, Ni, Se, Zn, Ag. In the STMP, 4 samples are taken in one year, then none for the next four years, then repeat. Fact Sheet NPDES N0002I 709 Renewal Page I Data submitted in discharge monitoring reports and PPAs from 2009 through 2010 were evaluated and a reasonable potential analysis (RPA) was done to determine whether effluent limitations or monitoring should be included in this permit renewal. Because of the C+ classification and the strategy to protect the ORW area downstream, one half the NC standard was used to develop the allowable concentrations for all metals except for mercury. For mercury, because of the statewide mercury impairment, the EPA recommended procedure of allowing no dilution for development of Hg limits was maintained, and therefore the NC standard of 12 ng/1 was applied, instead of halving the Hg standard to 6 ng/l. The RPA and effluent data is attached to the factsheet and the results are summarized below: o Monthly average and daily maximum limits for cadmium, cyanide and lead will be recommended based on the results of the reasonable potential analyses. The analyses indicated the reasonable potential for these parameters to exceed the North Carolina water quality standard in the receiving stream. These parameters will be limited and monitored monthly in accordance with DWQ guidance. o The daily maximum limit for mercury will be dropped from the permit based on the results of the reasonable potential analysis. However, quarterly monitoring for mercury will remain in the permit, based on the evaluation of the submitted data. o Silver monitoring will be dropped from the permit. There was no reasonable potential shown to exceed the water quality action level standard instream. All submitted silver data was below the laboratory detection level. Division guidance recommends that silver monitoring be continued in the pretreatment monitoring plan. o Copper and zinc monitoring will remain in the permit based on the results of the reasonable potential analyses. There was reasonable potential shown to exceed the water quality action level standard instream. These parameters will be monitored quarterly in conjunction with the whole effluent toxicity test. TOXICITY TESTING: Type of Toxicity Test: Existing Limit: Recommended Limit: Monitoring Schedule: Chronic Ceriodaphnia Pass/Fail (Quarterly) 001: Chronic P/F @ 30% 001: Chronic P/F @ 30% February, May, August, and November The facility has consistently passed its WET tests during this permit cycle. the quarterly test has been passed 17 times, with two invalid tests in 2009. It is recommended that the chronic pass/fail test be renewed in this permit. Since February 2007, COMPLIANCE SUMMARY: While overall compliance appeared to be good, the Jefferson WWTP did have violations of the lead limit in 2006, 2007 and 2009. DWQ actions included enforcement cases and notices of violation because of these violations. Past compliance evaluations of the facility have found the plant to be compliant with no major problems, reported. Fact Sheet NPDES NC002 1 709 Renewal Page 2 INSTREAM MONITORING: Upstream: 50 feet upstream Downstream: 250 feet downstream Parameters: Temperature and dissolved oxygen Reviewed instream data from 2008-2010 for the months of June through September. The review indicated that there were no DO stream standard violations downstream of the discharge for the past 3 years. Monthly downstream DO values ranged from 7.8 mg/1 to 9.6 mg/1. Recommend continuation of instream monitoring for temperature and dissolved oxygen. PROPOSED CHANGES: • Silver monitoring deleted because of RPA results and will continue to be monitored in STMP. • Mercury limit deleted because of RPA results, however quarterly monitoring will remain in the permit. • Monitoring for copper and zinc will be modified from 2/monthly to quarterly based on the results of the RPA and DWQ guidance for metals monitoring. • Limits for cadmium, lead, and cyanide will be in the permit and the monitoring frequency will be monthly based on the results of the RPA which indicated potential to exceed the NC standard instream and DWQ guidance for metals monitoring. • Existing permit limits and recommended limits/monitoring are summarized in the table below: Parameter Existing Limit (µto) Existing Monitorin g Proposed Limit (µid) Proposed Monitoring Cadmium none 2/month 3.4 (ma); 22.3 (dm) Monthly Lead 34 Weekly 42.1 (ma); 50.3 (dm) Monthly Cyanide none 2/month 8.4 (ma); 32.8 (dm) Monthly Mercury 0.04 Weekly none Quarterly Copper none 2/month none Quarterly Silver none 2/month none none Zinc none 2/month none Quarterly PROPOSED SCHEDULE FOR PERMIT ISSUANCE: Draft Permit to Public Notice: June 8, 2011 Permit Scheduled to Issue: August 2, 2011 (est.).

The EPA's concerns with the actions taken in the draft permit were discussed in depth with the DWQ staff on July 7, 2011, in a telephone conference call. To document those comments and in accordance with the EPA/North Carolina NPDES Memorandum of Agreement, we have completed our review of the above draft permit and have the following comments which should be addressed prior to final issuance: Background Jefferson Wastewater Treatment Plant is in the New River basin in the north western part of North Carolina and is rated a major facility because it has an active industrial pretreatment program. The plant discharges to Naked Creek which is subject to a special management strategy of the 15A NCAC 2B .0225 Outstanding Resource Waters rule to protect downstream waters of the South Fork and New rivers. Naked Creek is listed as impaired on the 2010 North Carolina impaired 303(d) list for degraded ecological/biological integrity within the fish community and is also 303(d) listed for mercury impairment based on the "statewide fish consumption advisory," and the state has not yet developed a Total Maximum Daily Load (TMDL) for Hg, nor has the state adopted the methyl -mercury fish -tissue criteria. The state water quality standard (WQS) for mercury is 0.012 µg/L (12 ng/L). Issue For development of the new draft permit, a reasonable potential analysis was performed and based on that analysis the permit writer proposes to remove the Hg limit and recommends "monitoring" only and to reduce the frequency of monitoring to quarterly. There are no apparent antidegradation issues, i.e., no new sources/dischargers to the facility, etc., however, the EPA contends antibacksliding provisions prevail because the previous permit had a Total Mercury weekly average limit of 0.04 µg/L and there is still no mercury TMDL with wasteload Internet Address (URL) • http://www.epa.gov Recycled/Recyclable • Printed with vegetable Oil Based Inks on Recycled Paper (Minimum 30% Postconsumer) allocations to address the statewide 303(d) listing. It is the antibacksliding provision of the Clean Water Act (CWA) that prohibits the removal of the previous permit's Total Mercury limit at this time. Specifically, CWA Section 303(d)(4)(A) prohibits the revision of any effluent limit for the impairing parameter, unless the "cumulative effect of all such revised effluent limitations" will assure the attainment of the WQS. Therefore, removal of the limit would only be allowed in the context of a TMDL or other watershed level analysis. Absent this type of analysis, the removal of the limit would not meet the 303(d)(4)(A) condition, and would therefore be prohibited under CWA 402(o)(1). Until the TMDL is developed, the EPA contends that the current end -of -pipe, weekly average limit of 0.04 µg/L for Total Mercury must remain in the new permit. This comment is consistent on a national basis with the EPA's implementation of CWA Section 303(d)(4)(A) for discharges into impaired waters prior to a TMDL. The EPA does not oppose reducing the frequency of monitoring to quarterly for this reissuance. We request that you address the concerns stated above prior to issuance and forward a copy of the final permit to the EPA. If you have any questions, please contact Ms. Pamala Myers of my staff at (404) 562-9421 or by email at myers.pamala®epa.gov. Sincere J Christopher B.

I see that this is a smaller facility, yet has an active pretreatment program and discharges to Outstanding Resource Waters (ORW). From your Fact Sheet and cover letter I understand that you have removed the previous permit limit for mercury based on the reasonable potential analysis (RPA). (You may wish to discuss this issue with Sergei, as he and I have been evaluating the removal of mercury limits from reissued permits affected by the statewide 303(d) listing for mercury impairment and how that can affect backsliding regulations.) I refer to criteria referenced at 40 C.F.R. §122.44(1) which triggers the anti -degradation and anti -backsliding evaluations - because of the 303(d) listing and need for a TMDL. For additional assistance, please refer to chapter 7 of the revised permit writers' manual for a diagram that can lead you through the determination process, specifically Exhibit 7-2 (included below for quick reference). At this time, my comment on this draft permit would be that you review your decision to remove the numeric limit for mercury from the permit because of the overriding criteria of anti -backsliding. I realize this is going to cause some considerable debate, however, please do not hesitate to call or respond back to this email if you have questions or can add clarifying comments to this draft permit submittal.

In addition to the conditions established under §122.43(a), each NPDES permit shall include conditions meeting the following requirements when applicable. (a) Technology -based effluent limitations and standards based on effluent limitations and standards promulgated under section 301 of CWA or new source performance standards promulgated under section 306 of CWA, on case -by -case effluent limitations determined under section 402(a)(1) of CWA, or on a combination of the two, in accordance with §125.3. For new sources or new dischargers, these technology based limitations and standards are subject to the provisions of §122.29(d) (protection period). (b)(1) Other effluent limitations and standards under sections 301, 302, 303, 307, 318 and 405 of CWA. If any applicable toxic effluent standard or prohibition (including any schedule of compliance specified in such effluent standard or prohibition) is promulgated under section 307(a) of CWA for a toxic pollutant and that standard or prohibition is more stringent than any limitation on the pollutant in the permit, the Director shall institute proceedings under these regulations to modify or revoke and reissue the permit to conform to the toxic effluent standard or prohibition. See also §122.41(a). (2) Standards for sewage sludge use or disposal under section 405(d) of the CWA unless those standards have been included in a permit issued under the appropriate provisions of subtitle C of the Solid Waste Disposal Act, Part C of Safe Drinking Water Act, the Marine Protection, Research, and Sanctuaries Act of 1972, or the Clean Air Act, or under State permit programs approved by the Administrator. When there are no applicable standards for sewage sludge use or disposal, the permit may include requirements developed on a case -by -case basis to protect public health and the environment from any adverse effects which may occur from toxic pollutants in sewage sludge. If any applicable standard for sewage sludge use or disposal is promulgated under section 405(d) of the CWA and that standard is more stringent than any limitation on the pollutant or practice in the permit, the Director may initiate proceedings under these regulations to modify or revoke and reissue the permit to conform to the standard for sewage sludge use or disposal. (c) Reopener clause: for any discharger within a primary industry category (see appendix A), requirements under section 307(a)(2) of CWA as follows: (1) On or before June 30, 1981: (i) If applicable standards or limitations have not yet been promulgated, the permit shall include a condition stating that, if an applicable standard or limitation is promulgated under sections 301(b)(2) (C) and (D), 304(b)(2), and 307(a)(2) and that effluent standard or limitation is more stringent than any effluent limitation in the permit or controls a pollutant not limited in the permit, the permit shall be promptly modified or revoked and reissued to conform to that effluent standard or limitation. (ii) If applicable standards or limitations have been promulgated or approved, the permit shall include those standards or limitations. (If EPA approves existing effluent limitations or decides not to develop new effluent limitations, it will publish a notice in the Federal Register that the limitations are "approved" for the purpose of this regulation.) (2) On or after the statutory deadline set forth in section 301(b)(2) (A), (C), and (E) of CWA, any permit issued shall include effluent limitations to meet the requirements of section 301(b)(2) (A), (C), (D), (E), (F), whether or not applicable effluent limitations guidelines have been promulgated or approved. These permits need not incorporate the clause required by paragraph (c)(1) of this section. (3) The Director shall promptly modify or revoke and reissue any permit containing the clause required under paragraph (c)(1) of this section to incorporate an applicable effluent standard or limitation under sections 301(b)(2) (C) and (D), 304(b)(2) and 307(a)(2) which is promulgated or approved after the permit is issued if that effluent standard or limitation is more stringent than any effluent limitation in the permit, or controls a pollutant not limited in the permit. (4) For any permit issued to a treatment works treating domestic sewage (including "sludge -only facilities"), the Director shall include a reopener clause to incorporate any applicable standard for sewage sludge use or disposal promulgated under section 405(d) of the CWA. The Director may promptly modify or revoke and reissue any permit containing the reopener clause required by this paragraph if the standard for sewage sludge use or disposal is more stringent than any requirements for sludge use or disposal in the permit, or controls a pollutant or practice not limited in the permit. (d) Water quality standards and State requirements: any requirements in addition to or more stringent than promulgated effluent limitations guidelines or standards under sections 301, 304, 306, 307, 318 and 405 of CWA necessary to: (1) Achieve water quality standards established under section 303 of the CWA, including State narrative criteria for water quality. (i) Limitations must control all pollutants or pollutant parameters (either conventional, nonconventional, or toxic pollutants) which the Director determines are or may be discharged at a level which will cause, have the reasonable potential to cause, or contribute to an excursion above any State water quality standard, including State narrative criteria for water quality. (ii) When determining whether a discharge causes, has the reasonable potential to cause, or contributes to an in -stream excursion above a narrative or numeric criteria within a State water quality standard, the permitting authority shall use procedures which account for existing controls on point and nonpoint sources of pollution, the variability of the pollutant or pollutant parameter in the effluent, the sensitivity of the species to toxicity testing (when evaluating whole effluent toxicity), and where appropriate, the dilution of the effluent in the receiving water. (iii) When the permitting authority determines, using the procedures in paragraph (d)(1)(ii) of this section, that a discharge causes, has the reasonable potential to cause, or contributes to an in - stream excursion above the allowable ambient concentration of a State numeric criteria within a State water quality standard for an individual pollutant, the permit must contain effluent limits for that pollutant. (iv) When the permitting authority determines, using the procedures in paragraph (d)(1)(ii) of this section, that a discharge causes, has the reasonable potential to cause, or contributes to an in - stream excursion above the numeric criterion for whole effluent toxicity, the permit must contain effluent limits for whole effluent toxicity. (v) Except as provided in this subparagraph, when the permitting authority determines, using the procedures in paragraph (d)(1)(ii) of this section, toxicity testing data, or other information, that a discharge causes, has the reasonable potential to cause, or contributes to an in -stream excursion above a narrative criterion within an applicable State water quality standard, the permit must contain effluent limits for whole effluent toxicity. Limits on whole effluent toxicity are not necessary where the permitting authority demonstrates in the fact sheet or statement of basis of the NPDES permit, using the procedures in paragraph (d)(1)(ii) of this section, that chemical - specific limits for the effluent are sufficient to attain and maintain applicable numeric and narrative State water quality standards. (vi) Where a State has not established a water quality criterion for a specific chemical pollutant that is present in an effluent at a concentration that causes, has the reasonable potential to cause, or contributes to an excursion above a narrative criterion within an applicable State water quality standard, the permitting authority must establish effluent limits using one or more of the following options: (A) Establish effluent limits using a calculated numeric water quality criterion for the pollutant which the permitting authority demonstrates will attain and maintain applicable narrative water quality criteria and will fully protect the designated use. Such a criterion may be derived using a proposed State criterion, or an explicit State policy or regulation interpreting its narrative water quality criterion, supplemented with other relevant information which may include: EPA's Water Quality Standards Handbook, October 1983, risk assessment data, exposure data, information about the pollutant from the Food and Drug Administration, and current EPA criteria documents; or (B) Establish effluent limits on a case -by -case basis, using EPA's water quality criteria, published under section 307(a) of the CWA, supplemented where necessary by other relevant information; or (C) Establish effluent limitations on an indicator parameter for the pollutant of concern, provided: (1) The permit identifies which pollutants are intended to be controlled by the use of the effluent limitation; (2) The fact sheet required by §124.56 sets forth the basis for the limit, including a finding that compliance with the effluent limit on the indicator parameter will result in controls on the pollutant of concern which are sufficient to attain and maintain applicable water quality standards; (3) The permit requires all effluent and ambient monitoring necessary to show that during the term of the permit the limit on the indicator parameter continues to attain and maintain applicable water quality standards; and (4) The permit contains a reopener clause allowing the permitting authority to modify or revoke and reissue the permit if the limits on the indicator parameter no longer attain and maintain applicable water quality standards. (vii) When developing water quality -based effluent limits under this paragraph the permitting authority shall ensure that: (A) The level of water quality to be achieved by limits on point sources established under this paragraph is derived from, and complies with all applicable water quality standards; and (B) Effluent limits developed to protect a narrative water quality a numeric water quality criterion, or both, are consistent with the assumptions and requirements of any available wasteload allocation for the discharge prepared by the State and approved by EPA pursuant to 40 CFR 130.7. (2) Attain or maintain a specified water quality through water quality related effluent limits established under section 302 of CWA; (3) Conform to the conditions to a State certification under section 401 of the CWA that meets the requirements of §124.53 when EPA is the permitting authority. If a State certification is stayed by a court of competent jurisdiction or an appropriate State board or agency, EPA shall notify the State that the Agency will deem certification waived unless a finally effective State certification is received within sixty days from the date of the notice. If the State does not forward a finally effective certification within the sixty day period, EPA shall include conditions in the permit that may be necessary to meet EPA's obligation under section 301(b)(1)(C) of the CWA; (4) Conform to applicable water quality requirements under section 401(a)(2) of CWA when the discharge affects a State other than the certifying State; (5) Incorporate any more stringent limitations, treatment standards, or schedule of compliance requirements established under Federal or State law or regulations in accordance with section 301(b)(1)(C) of CWA; (6) Ensure consistency with the requirements of a Water Quality Management plan approved by EPA under section 208(b) of CWA; (7) Incorporate section 403(c) criteria under Part 125, subpart M, for ocean discharges; (8) Incorporate alternative effluent limitations or standards where warranted by "fundamentally different factors," under 40 CFR Part 125, subpart D; (9) Incorporate any other appropriate requirements, conditions, or (other than effluent limitations) into a new source permit to the extent allowed by the National Environmental Policy Act, 42 U.S.C. 4321 et seq. and section 511 of the CWA, when EPA is the permit issuing authority. (See §122.29(c)). (e) Technology -based controls for toxic pollutants. Limitations established under paragraphs (a), (b), or (d) of this section, to control pollutants meeting the criteria listed in paragraph (e)(1) of this section. Limitations will be established in accordance with paragraph (e)(2) of this section. An explanation of the development of these limitations shall be included in the fact sheet under §124.56(b)(1)(i). (1) Limitations must control all toxic pollutants which the Director determines (based on information reported in a permit application under §122.21(g)(7) or (10) or in a notification under §122.42(a)(1) or on other information) are or may be discharged at a level greater than the level which can be achieved by the technology -based treatment requirements appropriate to the permittee under §125.3(c); or (2) The requirement that the limitations control the pollutants meeting the criteria of paragraph (e)(1) of this section will be satisfied by: (i) Limitations on those pollutants; or (ii) Limitations on other pollutants which, in the judgment of the Director, will provide treatment of the pollutants under paragraph (e)(1) of this section to the levels required by §125.3(c). (f) Notification level. A "notification level" which exceeds the notification level of §§122.42(a)(1)(i), (ii) or (iii), upon a petition from the permittee or on the Director's initiative. This new notification level may not exceed the level which can be achieved by the technology -based treatment requirements appropriate to the permittee under §125.3(c) (g) Twenty-four hour reporting. Pollutants for which the permittee must report violations of maximum daily discharge limitations under §122.41(1)(6)(ii)(C) (24-hour reporting) shall be listed in the permit. This list shall include any toxic pollutant or hazardous substance, or any pollutant specifically identified as the method to control a toxic pollutant or hazardous substance. (h) Durations for permits, as set forth in §122.46. (i) Monitoring requirements. In addition to §122.48, the following monitoring requirements: (1) To assure compliance with permit limitations, requirements to monitor: (i) The mass (or other measurement specified in the permit) for each pollutant limited in the permit; (ii) The volume of effluent discharged from each outfall; (iii) Other measurements as appropriate including pollutants in internal waste streams under 122.45(i); pollutants in intake water for net limitations under §122.45(f); frequency, rate of discharge, etc., for noncontinuous discharges under §122.45(e); pollutants subject to notification requirements under §122.42(a); and pollutants in sewage sludge or other monitoring as specified in 40 CFR Part 503; or as determined to be necessary on a case -by -case basis pursuant to section 405(d)(4) of the CWA.

I am requesting the following modification be taken under consideration during the renewal process. The Jefferson WWTP has monitored weekly for the previous four years for low level mercury using method 1631 E. In that period no mercury violations have occurred. In fact most of the data compiled is below detection level. For example, through November, 2010 forty seven samples were analyzed for mercury. Thirty seven were below detection level. The remaining ten were at detection level or only 0.002 ug/1 above detection. During this permit cycle all chronic toxicity analyses have passed. Method 1631 is quite expensive at over $140 per analysis. I feel this is an unnecessary burden upon the Town of Jefferson and the continuation of sampling at a weekly frequency is not justified in light of the data we have collected. Therefore I am requesting that NPDES # NC0021709 be modified to indicate low level mercury sampling at a frequency of once per quarter. In addition, I have attached results for ceriodaphnia and pimephales promelas chronic toxicity monitoring that were conducted in November subsequent to the submission of our permit renewal application. Thank you for your consideration of this modification request. I can be reached for questions or comments at (336) 246-2165 or by e-mail at jefiwns c ,centurvlink.net.

ASHE COUNTY. NORTH CAROLINA SHEET C2 Narrative for Process Flow Diagram Jefferson Wastewater Treatment Plant NC0021709 Influent flows enters the facility at the automatic bar screen. The headworks includes a manual screen as well to accommodate a by-pass of the unit in the event of repairs. Four influent pumps are located in the basement of the process building and are controlled by a float system in the wet well. Influent is pumped to the Oxidation Ditch where about 60 % of the flow enters the outside ring of the ditch and the remaining flow goes to the second ring. The oxidation ditch has two sets of rotors in each ring. One rotor operates continuously in each ring and the two are manually rotated as necessary to avoid excessive wear. Adjustment of flow and aeration to the first ring results in conditions that enhance nutrient removal. From the Oxidation ditch, flow enters the splitter box through which it may be directed and rate controlled to each clarifyer. A third compartment exists to accommodate a third clarifyer in the future. It is at this point where samples are taken for measuring settleability and MLSS. Two circular clarifyers operate in a parallel design. Return sludge from each enters the pump station located between clarifyer #1 and the circular digester. The pump station is valved to allow RAS to flow back to the Oxidation Ditch or it may be wasted to the twin sludge basins or the circular digester. After leaving the clarifyers, flow enters the dual tertiary filters, operating in parallel sequence. Backwash water from the filters flows by gravity back to the influent wet well. Disinfection is accomplished using chlorine gas fed to the front end of the chlorine contact chamber. This unit has around the end baffling for maximum contact time. At the end of the chlorine contact chamber a sodium thiosulfate solution is fed as a dechlorinating agent. This area also features a post aeration basin just prior to the outfall to the receiving stream. (Also attached to this narrative is the "Sludge Management Plan which should be helpful in interpreting the flow diagram.) Town of Jefferson Water Resources Sludge Manaiement Plan for Jefferson WWTP I. Sludge Storage Capacity Two sludge storage basins retrofitted with new headers and diffusers in 2004. 115,000 gallons Round digester 65,000 gallons Loading station 25,000 gallons Total sludge storage capacity 205,000 gallons II. Sludge Transfer through the Facility Sludge collected from the two clarifyers enters a pump station. Wasting is accomplished by diverting return activated sludge flow to the dual sludge storage basins. When the basins are filled, the aerators are turned off and the solids settle, allowing clear supernatant to be decanted using telescopic valves in each basin. The supernatant flows by gravity to the influent headworks of the WWTP At the completion of the dewatering procedure aeration is resumed and the thickened sludge is transferred to the round digester using a submersible pump located in each basin. The round digester has the same dewatering capability. Upon dewatering the round digester, thickened sludge is transferred by gravity flow to the loading station. Supernatant from the round digester enters the sludge pump station where it is transferred to the oxidation ditch. The thickened sludge from the round digester is transferred by gravity to the truck loading station for disposal to land application sites or to the belt press and sludge dryer. This plan allows a 2% total solids value for the sludge and results in a maximum detention time. M. Class B Liquid Sludge Permit WQ 0004166 regulates Class B liquid sludge disposal. Jefferson has forty two acres permitted for liquid sludge disposal. All the acreage is located within a two mile radius of the WWTP. The facility uses a military style ten wheel drive truck fitted with a tank capacity of 1800 gallons. Sludge leaves the tank through a spreader bar six feet in length, controlled by a pneumatic valve operated from the cab of the truck. Procedures to Significantly Reduce Pathogens is demonstrated by analysis of seven annual sludge samples for coliform bacteria, having a geometric mean < 2,000,000 MPN. Vector Attraction Reduction is demonstrated by volatile solids analysis of sludge in a thirty day bench scale shown to produce <15% volatile solids reduction. IV. Class A Dry Sludge Permit WQ 0022155 regulates Class A dry sludge production. This facility operates a Phoenix belt press with a capacity of 35 gpm. The cake from the belt press is augered to a Fenton sludge dryer. This unit generates a granular product with total solids > 90% and coliform bacteria are eliminated. This sludge is distributed on hay fields using an "eezee flow" drop spreader. (see the back of this page for details regarding Class A compliance under the 503 rules) Fenton Environmental Technologies, Inc. RK Series Municipal Biosolids Dehydrator, 1(800) 777-1371 Class A Compliance Under the 503 Rules The SludgeMASTER RK series automatic batch style biosolids dehydrator is uniquely suited to insure compliance with the 40 CFR 503 regulations pertaining to achieving Class "A" biosolids. The RK dehydration chamber is loaded automatically with a predetermined amount of dewatered biosolids which starts the batch cycle. The total sludge load is subjected to a minimum temperature of 212 degrees F for a minimum of two and one-half hours which exceeds the time and temperature requirements of the 503 regulations pertaining to pathogen reduction. This compliancy is shown as follows using Regime A under Alternative 1 which requires that solids be heated at 50 degrees C or higher for 20 minutes or longer. Time (in days) = 131.700,000 10A 0.14 (temperature) Qr, for the RK dehydrator at 212 degrees F (=100 C) Time= 131.700.000 gr Time= 131.700.00Q Qr Time = less than 1.3/10^6 day. 104 0.14(100) 10' 14 The time required in the RK for pathogen reduction would be less than 1 minute. Therefore, the minimum time requirement of 20 minutes specified in the 503 Rules must be followed. Following the 20-minute requirement, the RK dehydrator exceeds the time requirement by about 700%. Total cycle time is determined by achieving the desired sludge dryness. We normally recommend a minimum of 90 % dry solids for a finished product to qualify under 503.33 "Option-8" regarding vector attraction reduction. (Fully digested sludges need be dried to 75%- 503.33 "Option 7".) The SludgeMASTER RK patented process automatically adjusts the time and temperature regime foi the varying incoming wet sludge solids content. This feature is very important since dewatering operations will vary from time to time in solids consistency yet we must maintain consistent Class A biosolids at all times. Conversely, automatic flow through systems cannot adjust to varying conditions without disrupting their normal operation and compromising the finished Product Class "A" parameters. Please refer to 40 CFR 503.32 Pathogens - (a) (3) (ii) (9) for pathogen reduction requirements and to 40 CFR 503.33 (b) (7) and (8) for vector attraction reduction requirements. Fenton Environmental Technologies, Inc. guarantees Class A compliance on a continued basis with each SludgeMASTER RK Dehydration System. In choosing Class A biosolids thermal dehydration fit' i ' g SludgeMASTER RK technology, your utility will be assured of an environmentally correct sludge handling solution for many years in the future.
