(3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly at 0.925 MGD) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 1.5%. 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 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: Attention: North Carolina Division of Water Quality Environmental Sciences Branch 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 Branch 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 permit was originally issued on May 5, 2000 and expired on December 31, 2002. The Permittee submitted EPA Form 2A on July 2, 2002 in order to request renewal of the permit. Since this was prior to the full implementation of EPA renewal forms and associated pollutant analyses, these data are not necessary for this renewal, though they will be required for subsequent renewals. Murphy currently has a modified pretreatment program with the Division of Water Quality's Pretreatment Unit, but is in the process of implementing a full pretreatment program. This full program will be implemented in the new permit term. Prior to the last renewal, the Permittee requested and received permission for an expansion to 1.4 MGD. An Authorization to Construct (ATC) for this project was issued in March 2001. The Permittee anticipated completion in July 2002, but the Division received no engineering certification. Instream Monitoring, Verification of Existing Conditions and DMR Data Review This facility discharges to subbasin 04-05-02 in the Hiwassee River. At the point of discharge, the receiving waters bear a C classification. The Hiwassee River is not on the 2002-303(d) list. Effluent DMR data from January 2001 through May 2003 were reviewed; the Permittee is not re uired to collect instream data. Data for conventional earameters are summarized in Table 1. Avera • e Maximum Minimum Flow (MGD) 0.6461 0.9224 0.402 Temperature (°C) 17.81 25.22 10.48 BOD TSS (mg/L) Fecal (mg/L) (#/100 mL) 11.78 21.06 1.5 22.69 51.89 6.29 12.74 130.54 1.17 Table 1. NC0020940 Conventional Data (January 2001-May 2003) l 'i Sli t ♦1'I�I.ti \i .0l(i_'(ri'iddf Rcnewal As can be seen by the maximum Total Suspended Solids (TSS) value, the Permittee had several violations of its TSS monthly average limit during the permit term. These will be discussed further in the Correspondence section. This facility also collects data for total nitrogen, total phosphorus, and ammonia nitrogen (NH3- N). These are summarized in Table 2. Values for these pollutants of concern appear typical for this type of facility. Since August 2002, the facility has been achieving excellent ammonia nitrogen removal. Maximum Minimum NH3-N Total Nitrogen Total (mg/L) (mg/L) Phosphorus (mg/L) 4.65 10.9 0.03 12.13 15 7.4 1.15 2.5 0.22 Table 2. NC0020940 Nutrient Data (January 2001— May 2003) A review of the metals (from both the DMRs and Pretreatment data) and toxicants was also performed. With the exception of total residual chlorine (TRC), these are discussed in the Reasonable Potential Analysis section. TRC was not detected in the period of review. Correspondence The Asheville Regional Office (ARO) conducted several site visits during this permit term to evaluate compliance. ARO states that the plant is well operated, but is aging. The inspections also note deficiencies in the implementation of the Pretreatment Program, for which Murphy has received several Notices of Violation (NOVs) and a civil penalty assessment. In addition to the NOVs noted above, Murphy has received four NOVs for violations of the Total Suspended Solids monthly average limit (between 7/00 and 4/01). No additional NOVs were noted in the correspondence file review and it appears that the facility has been completely in compliance since the last violation in April 2001. PERMITTING STRATEGY Waste Load Allocation (WLA) The Division prepared the last WLA for the previous permit renewal. The previous and current effluent limits were based on guidelines and water quality standards. The Division has judged previous parameters and limits to be appropriate for renewal with some exceptions. Changes to toxicant monitoring are discussed in the Reasonable Potential Analysis section. The Instream Waste Concentration (IWC) used for the 1.4 MGD flow in the existing permit was calculated incorrectly. The actual IWC is 2.2%. Toxicity testing language will be changed accordingly. An annual pollutant scan will be added such that the Permittee can collect the necessary data required by EPA Form 2A throughout the permit term. This condition is now standard on all major municipal permits in North Carolina. Reasonable Potential Analysis (RPA) The Division conducted EPA -recommended analyses to determine the reasonable potential for toxicants to be discharged by this facility, based on DMR data from January 2000-May 2003. Calculations included parameters listed in the previous permit and pre-treatment documents to include: arsenic, cadmium, chromium, cyanide, lead, mercury, nickel, silver, selenium, copper, and zinc. Results suggest no reasonable potential for the facility to discharge arsenic, cadmium, chromium, lead, nickel, selenium, copper, and zinc any of these parameters. Those that are currently monitored through the NPDES permit may be eliminated from the permit, as they will continue to be monitored on a monthly basis through the pretreatment program. iaci sheet \ I' I ) I \ (002O940 Renewal Page 2 Reasonable potential to exceed water quality criteria was found for cyanide, mercury and silver. All are currently monitored through the NPDES permit, but mercury and cyanide are not limited. Mercury will have an increased monitoring frequency of weekly and a daily maximum limit of 0.8 µg/L at 0.925 MGD and 0.614/L at 1.4 MGD. Cyanide will also have an increased monitoring frequency of weekly. At 0.925 MGD, cyanide will have a weekly average limit of 34314/L and a daily maximum average of 2214/L. At 1.4 MGD, cyanide will have a weekly average limit of 228 µg/L and a daily maximum limit of 22 µg/L. Silver will continue to be monitored at a weekly frequency. SUMMARY OF PROPOSED CHANGES In keeping with Division policies, the following will be incorporated into the permit: • Annual pollutant scan • Elimination of the monitoring requirements for cadmium, chromium, cyanide, lead, nickel, copper, and zinc • Addition of daily maximum limit and increase to weekly monitoring for mercury • Addition of weekly average and daily maximum limits (and increase to weekly monitoring) for cyanide • Change to IWC for toxicity test at 1.4 MGD New Weekly Average and Daily Maximum limits are derived from the latest NC/EPA policies considering/ FAVs and allowable concentrations based on reasonable potential.

Subject: Town of Murphy From: Natalie.Sierra@ncmaiLnet Date: Tue, 26 Aug 2003 14:08:39 -0400 To: charles.weaver@ncmail.net Charles - I guess this is how we're doing notice stuff. The attached documents relate to the Town of Murphy. The water quality limited parameters are mercury and cyanide. I usually print out the first page (RPA summary page) of the RP spreadsheets. There is also a DMR summary page in the DMRS spreadsheet (I'm not sure if it's labeled on this one, but it is obvious, as it is formatted like a table. That's it for this one, you can always holler my way if there is something ambiguous. I'm also going to try to get La Grange and Spruce Pine to you in a little bit. (Sorry Mike T. just sent me changes late last night). Thanks, Natalie 1 of 1 8/27/2003 6:01 AM / : 971 r- , `/ 1 4 ` ' • Ie •/' t 0 c \ .. , / \._'..2-/-:." -'• \ • ) c-g;,../.- •__,.

Here are the fcw comments I can offer on the drafts. All appear ready to go forward with little or no change on your part. Once you have them ready, pis forward them to Charles. I noticed some minor formatting corrections (odd page breaks, for instance), but I'll leave it to Charles to look at the documents and make any necessary changes before he prints them out. Elizabethtown - Looks good - go for it. Murphy - In the cover letter, you shouldn't have to apologize for past errors. Suggest you word it in a more straightforward way: "The Instream Waste Concentration (IWC) for the toxicity limit at 1.4 MGD has been changed to 2.2% to correct an error in the previous permit renewal." Spruce Pines - A couple of points in the fact sheet may be worth clearing up: It sounds like the Town expanded its plant to handle the higher flows caused by I/I rather than fix the I/I problem. Is that correct? Also, it sounds like all of the industrial users left once the Town started implementing its pretreatment program. Is that how it went? La Grange - One minor point - the table on p.1 of the Fact Sheet gives an IWC of "90% for toxicity purposes." Since there is no tox limit, should this be dropped to avoid confusion? Contentnea MSD - There is a potential issue regarding "effluent channel" status and their discharge point - did the Region ever mention the issue? It came up during the 2000 renewal but was never resolved that I know of. In short, the plant discharges to a man-made channel, several hundred yards long, that runs to the creek. Our limits are based on the IWC at the creek; it appears they should be changed to reflect the IWC in the channel (approx. 100%). That's it. I'll be gone Tuesday, back on Wednesday. See you then (so to speak). - Mike T Michael E. Templeton, P.E.

The Town of Murphy is requesting renewal of its NPDES wastewater permit. The permit was modified May 5, 2000 and took affect on June 1, 2000. The permit was modified because of construction of a new facility. The facility is to be completed around July 1, 2002. All permit effluent limitations and monitoring requirements will take affect when the new facility receives flow. Sludge that is generated by the Town of Murphy will be aerated in aerobic digesters until oxidized and will then be ran through a sludge press. Final disposal of sludge will be in the Cherokee County Landfill. All analyses and requirements are performed by the Town of Murphy to ensure local and state regulations are met.

The discharged wastewater in the equalization tank is allowed to settle and is pumped off into the chlorine contact tank and then sulfur dioxide is added before discharging to the river. A back-up generator is onsite for any power failure.
