Klimek, P.E., Director Division of Water Quality September 29, 2006 Mr. Richard Canipe, Manager Town of Spruce Pine P.O. Box 189 Spruce Pine, North Carolina 28777 Subject: Issuance of NPDES Permit NCO021423 Spruce Pine WWTP Mitchell County Dear Mr. Canipe: 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). This final permit contains the following significant changes from the draft you were sent on July 19, 2006: ➢ The 0.5 MGD flow tier will remain in effect until a 12-month (calendar year) average flow exceeds 0.45 MGD. Please note that the draft hermit contained two maior items that were not noted in the cover letter. A 2.0 pg/L cadmium limit was added based on reasonable potential for levels present in your effluent to cause an exceedance of acute water quality criteria. This requirement applies at both flow tiers, however the 0.5 MGD tier requires monitoring twice per month while the 2.0 MGD tier requires weekly monitoring. Also, an annual priority pollutant scan was added at both tiers. By performing this scan concurrent with your toxicity test (at different times of the year), you will be able to collect sufficient data for the new renewal application required by the Environmental Protection Agency (EPA). 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 demand is made, this decision shall be final and binding. Please note that this permit is not transferable except after notice to the Division. 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 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone (919) 733-7015 FAX (919) 733-0719 NorthCarolina 512 N.

(3) 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 6.6%. 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 11 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 If 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 TGP313 for the pass/fail results and THP313 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. The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 6.6%. Pemi t NCO021423 A.

II. Summary The Spruce Pine W WTP is a 2 MGD facility discharging to North Toe River, a C Trout waterbody. This segment of the North Toe River was newly added to the state's draft 2006 303(d) List due to aquatic life impairment based on turbidity standard violations and impaired biological integrity. No potential sources were listed. The WWTP has a modified pretreatment program with only one SIU. Bombardier Motor Company manufactures aluminum motors and discharges approximately 18,000 gpd from two outfalls. Based on the requirements of their STMP, they were last required to monitor in 1999 and the next cycle begins in 2010. Therefore no pretreatment data was used in this analysis. III. Compliance Summar DMR Data Review Monthly average DMR data was reviewed for the period of January 2003 through February 2006. A summary of this data is included in Table 1. During this period the facility experienced average monthly flows at 16% capacity and maximum monthly average flows at 20% capacity. NPDES Permit Fact Sheet - 09/26/06 Town of Spruce Pine Page 2 NCO021423 The regional office has indicated that the facility recently repaired an I/I problem in the collection system and as a result the flows are expected to decrease by an additional 10%. The regional office did not anticipate that average flows would increase in the foreseeable future. A limits page will be added containing monitoring requirements for a class II facility and will remain in effect as long as a 6-month consecutive average remains below 0.5 MGD.

From this data it appears that the discharge has very little, if any, effect on the receiving stream. The facility currently has instream monitoring requirements to align with those for class III facilities. On the 0.5 MGD tier, these requirements will be reduced to weekly, year-round to align with requirements for class II facilities. Instream fecal coliform monitoring will be removed at both tiers since the waterbody is not impaired due to coliform. Upstream Downstream TTFecal ) Colifform ..

Mercury monitoring will be removed from the permit due to a lack of reasonable potential for levels of this parameter to cause an exceedance of water quality standards. Copper and zinc monitoring will remain in the permit based on effluent levels and the fact that these are action level parameters. The frequency of copper monitoring will be increased to align with zinc monitoring. The highest reported cadmium concentration was well above both the acute and chronic allowable concentrations. The acute criterion is more stringent therefore a daily maximum limit will be added to the permit. WET Test Results The Spruce Pine WWTP has a chronic WET test requirement at 6.6%effluent concentration. They have passed 19/19 tests administered since February 2002. Correspondence File Review/Compliance History The facility has not had a permit limit violation since November 2002. In late 2002 there were several mercury limit violations that lead to an enforcement case, but the issue has been resolved. Mercury data reviewed since 9/2003 (since the facility switched to Method 1631) yields a maximum predicted concentration of 31.9 ng/L versus an allowable concentration of 180 ng/L.

Therefore, I assume this is in error and should reflect the last permit's requirement for Cd monitoring of 2/month with no limit. The Annual Pollutant Scan has been added to the permit with no explanation to the permittee about the need for this new requirement; there is no mention of this addition in the cover letter. The permittee should be given an explanation for this new requirement. The 0.5 MGD flow tier needs a statement at the top of the page regarding when this tier is effective.

How about making it 6 months average flow. I don't think their flow is going to increase unless they increase their I&I on purpose. FYI - I got a call from Spruce Pine last month, letting me know that they had repaired an I&I problem in their collection system. The result of the repair was a 10% reduced flow to the WWTP. Thanks Larry Toya Fields wrote: Hi Larry, I'm drafting the permit for the Spruce Pine WWTP. It looks like their flows are really low. They are permitted for 2 MGD and their highest monthly average flow for the past few years has been 0.4 MGD. They are a class III facility but I could give them a limits page with reduced monitoring (for class II facilities) as long as they are under 0.5 MGD. I received a similar request recently from another facility and I think I worded it so that they could do the reduced monitoring as long as a four month average was under 0.5 MGD. Mike Mickey recommended the 4 -month average in that case. Thoughts?
