Box 339 Valdese, North Carolina 28690-0339 46-1,7•11rA NCDENR Subject: NPDES Permit Modification Permit No. NC0041696 Town of Valdese — Lake Rhodhiss WWTP Burke County Dear Mr. Morse: In accordance with your request for a re-evaluation of the effluent limitation and monitoring for mercury as in the current NPDES discharge permit, staff has reviewed the data submitted in the March 5, 2002 letter. A statistical analysis of the data was performed to determine the potential for exceedance of the instream water quality standard for mercury. The results indicated that there was no potential for the standard to be violated based on the data. Therefore, the NPDES Unit is recommending that the effluent limitation and monitoring requirement for mercury be removed from the Valdese permit. Mercury data will still be collected through the facility's pretreatment program and will be evaluated upon permit renewal in 2005. The Town of Valdese should be aware that mercury continues to be a water quality concern throughout North Carolina. Holders of NPDES permits have worked with the state to reduce potential risks from this pollutant, including tasks associated with collecting and reporting more accurate data. The most commonly used laboratory analysis (EPA Method 245.1) has a detection limit of 0.2 ug/L while the current water quality standard is an order of magnitude lower at 0.012 ug/L. A more recently approved analytical test (EPA Method 1631) should produce a detection limit below the level of the standard. This will allow the Division to assess potential water quality impacts from discharges more accurately. Therefore, beginning on or before September 1, 2003, you will be required to begin using EPA Method 1631 when analyzing for mercury. Accordingly, we are forwarding herewith these modifications to the subject permit. Please find enclosed the amended effluent pages for outfall 001, which should be inserted into your permit. The old pages should be discarded. 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. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone 919-733-5083 FAX 919-733-0719 An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper Permit No. NC0041696 Valdese WWTP May 31, 2002 Page 2 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.

Box 339 Valdese, North Carolina 28690 (828) 879 - 2131 March 5, 2002 Mr. Dave Goodrich NCDENR Division of Water Quality NPDES Unit Dear Mr. Goodrich, OdL� MAR - 8 2002 In late 2000, the Town of Valdese received a draft permit for the Lake Rhodhiss Wastewater Facility. In that permit, it was recommended that mercury be monitored weekly with a 0.25 rrg / 1 limit, which we felt was excessive because of low historical occurrences in our discharge. Upon mediation with Jacquelyn Nowell, we agreed with a monitoring frequency of twice per month for a period of 1 year. And if during that timeframe, our effluent showed no signs of mercury, we could submit a request to the NPDES Unit asking for the removal of this characteristic from our permit and sampling routine. At this point in time, we formally request the removal of mercury monitoring from the permit. Analytical results for the past 12 months are enclosed for your review and show that each instance yielded a non -detect (ND). If there are concerns regarding the removal, we ask for another mediation period or that contact is made with Alan Abee (Plant Superintendent) and/or Chris Bortnick (Lab Director) for this facility. We thank you for your attention in this matter. Sincerely, cc: Jeffrey V. Morse / Town Manager www. paaa: a'lals. cons Pace Analytical Services, Ins. 9800 kon;et AvPrrae ;4!
