Box 190 Albemarle, North Carolina Dear Mr. Smith: October 23, 2000 28002-0190 AVA NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES Subject: Issuance of NPDES Permit NC0024244 Long Creek WWTP Stanly County 4 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 the North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the US Environmental Protection Agency dated May 9, 1994 (or as subsequently amended). The following changes were made to the final permit in response to your comment letter dated August 21, 2000: ➢ The instream monitoring frequency for Dissolved Oxygen, Temperature, Conductivity, and Color has been revised to reflect the monitoring frequency listed in your previous permit. ➢ A second review of the Reasonable Potential Analysis (RPA) indicated that limits for Mercury and Cyanide are no longer required. The limits and monitoring requirements for these two parameters have been dropped. ➢ The limit for Cadmium will remain in the permit due to the results of the RPA. The maximum predicted concentration was calculated to be 4.35 µg/l while the allowable concentration was calculated to be 2.1 µg/l. Therefore, a weekly average limit of 2.1 µg/1 and a daily maximum limit of 15.0 1..t,g/1 was included in the permit. Your facility can apply for a permit modification to have this limit removed once the facility collects 12 consecutive months of monitoring data showing levels are below detection. ➢ The permit has been revised to include a 62% removal requirement for Total Suspended Residue as requested. 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 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.

Downstream3 (for color samples) = approximately 200 yards downstream from the discharge point. Upstream and downstream samples shall be grab samples. Stream samples shall be collected once per month in the winter (October through May) and once per week during the summer (June through September). 2. The monthly average effluent BODS concentration shall not exceed 15 percent of the respective influent value (85 percent removal). The monthly average Effluent Total Suspended Residue concentration shall not exceed 38% of the respective influent value (62% removal). 3. The daily average dissolved oxygen effluent concentration shall not be less than 5.0 mg/l. 4. Chronic Toxicity (Ceriodaphnia) at 90%: March, June, September, & December (see Part I. A. (2.)). 5. See Part I. A. (3.). 6. The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units. There shall be no discharge of floating solids or visible foam in other than trace amounts. Permit NC0024244 A. (2.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dabia at an effluent concentration of 90%. 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: NC DENR / DWQ / 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. Permit NC0024244 A. (3.) COLOR REOPENER AND MONITORING REQUIREMENTS This permit will be modified or revoked and reissued to incorporate color limitations and /or revised monitoring requirements in the event color testing or other studies conducted by the permittee or the Division indicate that color has rendered or could render the receiving waters injurious to public health, secondary recreation, to aquatic life and wildlife or adversely affect the palatability of fish, aesthetic quality or impair the water for any designated use. Color monitoring should consist of ADMI monitoring as specified below. All samples taken should have complete descriptive recordings of the color in the sample container including hue (distinctive characteristics and tint), clarity (clearness of the color sample) and luminance (brightness or glowing quality) of the sample as it looks in the collection container. Descriptions of stream color should also be recorded when color samples are collected. Color samples should be analyzed as follows: > At natural pH; > Free from turbidity (true color); and > Samples shall be analyzed in accordance with the provisions of Method 2120.E.4 as described in the 18'h edition of Standard Methods for the examination of Water and Wastewater. Using a narrow -band scanning spectrophotometer to produce a COMPLLETE spectral curve of the visible spectrum (350-750 nm), calculate and report results in ADMI values for true color values at the samples ambient pH value. All color data including visible observations should be submitted with the monthly DMRs. }l; `, .the Stanly News and Press �Y " P.O.

Notary: hereunto My Commission Expires: 1/ 43 t( cc, a t' City of Albemarle North Carolina Office of Public Utilities Treat/nun Plants (704) 984-9630 August 21, 2000 Mr. Jeffrey T. Myhra N. C. DENR Division of Water Quality NPDES Unit 1617 Mail Service Center Raleigh, NC 27699-1617 SUBJECT: Requests for modifications Draft NPDES Permit Permit NC0024244 City of Albemarle WWTP Stanly County Dear Mr. Myhra: Mailing Address P. O. Box 190 -Albemarle, N. C. 28002-0190 The City of Albemarle received the draft NPDES Permit NC0024244 for the Wastewater Treatment Plant on August 7, 2000. After review of this document, there are several concerns about how these new additional requirements will impact the City of Albemarle. The following is a summary of objections and comments on the new changes incorporated in the proposed permit: Item 1. lnstream Monitoring Frequency /Thisis the third consecutive permit renewal this item has come up. The major problem that the City has is the accessibility of the downstream sampling point (D2) at NCSR 1960. There have been at least a dozen letters written back and forth between the City and the State on this matter in the past 11 years. If you do not have any of this correspondence, I can provide copies of most of these letters. The City has always requested to have this sampling point completely removed. However, the State has never agreed to this, so the City and the State reached a compromise, which is the instream monitoring frequency in the last issued NPDES Permit to the City of Albemarle. The City of Albemarle requests that the instream monitoring frequency remain the same for the new NPDES permit as in the current permit. i Besides Cadmium these items have never been limited in past NPDES permits. What is the rationale for issuing limitations on these parameters at this time? The City of Albemarle has passed the Chronic Toxicity requirement consistently over the past few years. The letter states these limits are proposed due to "the reasonable potential analysis." What data is this analysis based on? j;,n,;-co(' z. The data the City of Albemarle has collected for Mercury is not extensive. The discharge limit of lAd "0.012 ug/1 of Mercury is below the detection level of 0.2 ug/l that has been reported by this facility. If GJAA a 9°"mod` Item 2. Daily Maximum Limits for Cadmium, Cyanide, and Mercury 5� the City\of Alb marlereetp orts a effluent result of <0.2 ug/1 for Mercury will this be considered a violation?L--.� The accuracy of laboratory results for Cyanide at the 5.3 ug/1 discharge limit is very questionable. I understand several other municipalities have raised this topic. Looking over the past 30 months data fl have seen two instances were the City would have exceeded the limits for Cadmium and Cyanide. Howeve sI question the accuracy of these results. The City feels there is not significant evidence to uo issue Daily Maximum Limits for Cadmium, Cyanide, and Mercury. NO L Y'; The City of Albemarle requests that the Daily Maximum Limits for Cadmium, Cyanide, and Mercury /be removed from the proposed NPDES Permit. The City of Albemarle proposes that monitoring be conduct d for the above -mentioned parameters twice per month for at least one year. This will give everyone involved enough data to see if a Daily Maximum Limit is warranted for any of these parameters. Item 3. Percent Removal of Total Suspended Residue This item has also been discussed on permit renewals in the past. The City of Albemarle receives a >l significant amount of textile waste that is low in Total Suspended Residue. For that reason the City of Albemarle was issued a 62 percent removal for Total Suspended Residue in its past two NPDES Permits. The City of Albemarle requests that the Total Suspended Residue Percent Removal be 62% as it is in the present NPDES Permit. If you have any questions feel free to contact me at (704) 984-9630. I appreciate your consideration in this matter. Sincerely. Gary O. Smith, II Superintendent of Wastewater Treatment DENR/DWQ FACT SHEET FOR NPDES PERMIT DEVELOPMENT NPDES No. NC0024244 NC..

The results of the analysis are attached to this document. In summary, Cadmium The maximum predicted concentration was determined to be greater than the allowable concentration. Therefore, a limit was included in the permit renewal. Selenium The maximum predicted concentration was determined to be less than the allowable concentration. Therefore, no limit will be included in the renewal. Cyanide The maximum predicted concentration was determined to be greater than the allowable concentration. Therefore, a limit was included in the permit renewal. Lead The maximum predicted concentration was determined to be less than the allowable concentration. Therefore, no limit will be included in the renewal. Nickel The maximum predicted concentration was determined to be less than the allowable concentration. Therefore, no limit will be included in the renewal. Chromium The maximum predicted concentration was determined to be greater than the allowable concentration. Therefore, the limit of 53.0 µg/1 will remain unchanged in the permit renewal. Copper Monitoring only for copper will remain in the permit. This parameter has an action level of 7 µg/l. - Mercury, The maximum predicted concentration was determined to be greater than the allowable concentration. Therefore, a limit was included in the permit renewal. - Zinc Monitoring only for zinc will remain in the permit. This parameter has an action level of 50 µg/1. Arsenic The maximum predicted concentration was determined to be less than the allowable concentration. Therefore, no limit will be included in the renewal. • WLA Review: Most recent staff report was prepared in July of 1994. Limits were determined to be water quality limited and instream monitoring was DENR/DWQ FACT SHEET FOR NPDES PERMIT DEVELOPMENT NPDES No. NC0024244 (Continued) recommended for DO, Fecal Coliform, Temperature, Conductivity and color. In addition, the following metals monitoring requirements were recommended: Chromium at 53 µg/1; copper monitoring and zinc monitoring. Monitoring for color (ADMI) was also recommended. • DMR Data review: In general, the facility appears to be in compliance with the conditions of the permit. The following issues were noted in reference to the DMR review. The following is a summary of the monthly average levels reported during 1998 and 1999: Summer TRC levels range from <0.1 ug/1 to 0.2 ug/1 BOD levels range from 4.4 mg/1 to 7.4 mg/1 Ammonia levels range from 0.1 mg/1 to 0.4 mg/1 TSS levels range from 6 mg/1 to 14 mg/l Fecal Coliform levels range from 4 #/100m1 to 13 #/100m1 DO levels range from 5.5 mg/1 to 7.1 mg/1 TN levels range from 2.4 mg/1 to 7.2 mg/l.

The sludge generated by the facility is treated in the following manner: The sludge from the secondary clarifiers has already been treated by extended aeration before it is pumped to two aerobic digestors. The sludge is aerated in these digestors. This sludge can then be gravity thickened or transferred to a Dissolved Air Floatation Unit (under repair). In either process the sludge is normally between 4-6% solids. The sludge is then pumped to two storage tanks approximately 0.6 MG each. From there the sludge is land applied. The sludge from the primary clarifiers is disposed of in the same manner as above and can also be lime stabilized in a 0.15 MG storage tank
