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 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 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 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 Permit NC0024244 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. 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 impact 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: D. 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 18th edition of Standard Methods for the examination of Water and Wastewater.

The permittee's 5-year NPDES permit expire at midnight on February 28, 2009 and have requested permit limits modification from the Division of Water Quality. This Fact Sheet summarizes background information and rationale used by the Division's NPDES Unit to determine permit limits and monitoring frequencies revision. FACILITY DESCRIPTION Albemarle is a publicly owned treatment works (POTW) utilizing a Grade IV activated sludge wastewater treatment facilities to treat domestic and industrial wastewater. The treatment system utilizes a mechanical bar screen, dual gravity grit removal device, primary clarifiers, aeration basins, tricking filters, secondary clarifiers, aerobic digesters, chlorination units, centrifuge and flow meters. Table 1. Summarizes the receiving stream characteristics and facility description. Table 1. Albemarle WWTP Facility Information Applicant/Facility Name City of Albemarle WWTP Applicant Address P.O. Box 190, Albemarle NC 28002 Facility Address Coble Avenue Extension, Permitted Flow (MGD) 16.0 MGD Type of Waste Domestic / Industrial Facility Class Class IV County Stanly Facility Status Modification Regional Office Mooresville Stream Characteristics Receiving Stream Long Creek Stream Classification C Y#in-Pee Dee Drainage Area (sq. mi.) 64 Drainage basin Summer 7Q10 (cfs) 1.6 Subbasin 03-07-13 Winter 7Q10 (cfs) 9.5 Use Support Yes 30Q2 (cfs) 4.7 303(d) Listed No Average Flow (cfs) 64 State Grid Albemarle IWC (%) 94 USGS Topo Quad F 18 SW Fact Sheet Renewal -- NPDES Permit NC0026514 Page 1 The facility serves the City of Albemarle (-15500 people), Stanly County (-2800 people) and the Town of New London (-275 people). Albemarle has full pre-treatment program with a Long Term Monitoring Plan and has four significant industrial users and one categorical industrial user. The facility has a permitted flow rate of 16.0 MGD discharging into the Long Creek. For the past twelve consecutive months, the monthly average flow varied within the range of 5.78 —12.02 MGD as reported in the Discharge Monitoring Report (DMR). BASINWIDE PLAN The City of Albemarle — Long Creek WWTP discharges into Long Creek in the Yadkin -Pee Dee River Basin. The stream classification of this segment of the Long Creek is C. The receiving stream has a use rating of support threatened. The basin plan discusses problems with low dissolved oxygen above and below the Albemarle WWTP discharge. Recommendations were for the City of Albemarle to optimize its WWTP treatment processes in order to minimize impacts to Long Creek. The plan also recommends that DWQ consider reducing summer BOD limits from 10 mg/1 to 5 mg/1 during the next permit cycle (Yadkin - Pee Dee River Basinwide Water Quality Plan, 2003). INSTREAM DATA REVIEW Instream monitoring is required for temperature, dissolved oxygen, conductivity and color. Instream monitoring data was reviewed for the period beginning May 2004 through May 2006. Review of instream data showed that in 2004 and 2006, the dissolved oxygen standard of 5 mg/1 was met at all stations upstream and downstream of the WWTP. However, in 2005, there were summer months where upstream and downstream DO values were below the standard of 5 mg/1. Based on this data, we recommend that the instream monitoring frequency remain at once per week in the summer and once per month in the winter. the instream color monitoring program. WASTE LOAD ALLOCATION (WLA) The Division prepared the last WLA for the receiving stream in October 25, 1993 and developed effluent limits and monitoring requirements considering an in -stream waste concentration (IWC) of 94 % at 16.0 MGD. The Division views these limits and monitoring requirements appropriate. TOTAL RESIDUAL CHLORINE (TRC) The permittee currently uses chlorine for disinfection. The Division has implemented TRC policy to protect aquatic life in the waters of the State and has adopted aquatic life standard for Fact Sheet Renewal -- NPDES NG0026514 Page 2 TRC. A TRC limit of 18 ug/1 is added to this permit to be consistent with the Division's TRC policy. The limit will be effective January 1, 2007. REASONABLE POTENTIAL ANALYSIS (RPA) To establish a list of pollutants of concern (POCs), the Division examined Albemarle's two years of pretreatment data, Discharge Monitoring Reports, and the basin plan. The Division then applied the reasonable potential analysis to calculate a maximum predicted concentration for each POC. Each maximum predicted concentration was then compared to the POC's freshwater standard/criterion or allowable concentration considering dilution. If by this method, a POC showed reasonable potential to exceed its standard or criterion, the Division included a limit in the permit as a weekly average to protect the receiving stream against chronic toxicity impact, and as a daily maximum against acute toxicity impact. The following parameters are monitored through the current permit: mercury, chromium, copper, cyanide, selenium and zinc. The following parameters are monitored quarterly through the pretreatment program: arsenic, cadmium, chromium, copper, cyanide, lead, mercury, molybdenum, nickel, silver, selenium, zinc, and ammonia. A reasonable potential analysis was performed on the following parameters: chromium, copper, mercury, silver and zinc. Results and data analysis are attached. RPA RESULTS: Based on the results of the Reasonable Potential Analysis: • Limit for chromium should be deleted. RPA results for chromium had maximum predicted concentration less than the allowable concentration. Monitoring is not required in the permit for chromium. Albemarle shall continue monitoring through the Long Term Monitoring Plan in the pretreatment program. • Limits for cyanide and selenium should.be deleted. Cyanide and selenium results had fifty-two (52) reported values each and all were below detection. No RPA was performed on these parameters. • No limit and monitoring should be added for arsenic, cadmium, lead, nickel and molybdenum in this permit. The reported values for these parameters in the DMR were below detection. • 2/month monitoring for copper and zinc should be continued in the permit. RPA results showed the maximum predicted concentrations exceeding the allowable action level concentration. • 2/month monitoring for silver should be added to the permit. RPA results showed the maximum predicted concentration exceeding the allowable action level concentration. Fact Sheet Renewal -- NPDES NC00265 l4 Page 3 • Weekly average limit of 0.013 ug/l for mercury should be continued in the permit. The parameter showed reasonable potential to exceed the maximum allowable concentration. WHOLE EFFLUENT TOXICITY (WET) TEST AND AMMONIA Type of Toxicity Test: Existing Limit: Recommended Limit: Monitoring Schedule: Chronic P/F (Quarterly) 001: Chronic P/F @ 90% 001: Chronic P/F @ 90% March, June, September, and December. The permittee has passed eighteen out of nineteen WET tests from 2002 to 2006. The permittee failed effluent toxicity tests in March 2003. COMPLIANCE REVIEW Mooresville Regional Office (MRO) staff conducted an annual facility inspection on October 24, 2005. The MRO staff found the facility in satisfactory condition and in compliance with the permit. BIMS records indicated the facility had a few permit limit violations during the May 2004 through May 2006 reporting period. Albemarle had violated mercury daily maximum limit during the months of December 2006 and January 2006. Notices of violations were issued for these violations. PROPOSED CHANGES • Monitoring Frequencies: • Weekly monitoring for chromium, cyanide and selenium have been deleted because these pollutants presented no reasonable potential to exceed water quality standards based on the statistical analysis of the effluent data. ■ 2/month monitoring for silver has been added since there was reasonable potential to exceed action level standard. • Limits: • Daily maximum limits for chromium, cyanide and selenium have been deleted because these toxicants presented no reasonable potential to exceed water quality standards. Fact Sheet Renewal -- NPDES NC0026514 Page 4 • Limit for mercury has been changed from daily maximum to weekly average to accurately reflect the duration that the chronic criterion is based. Otherwise a daily maximum limit would be more representative of an acute criterion. • Priority pollutant scan has been added to fulfill EPA's permit renewal application requirement for major municipal wastewater treatment facilities.

Since the location of this plant and its discharge, the Creek has been completely unusable for safe recreation or fishing, and the odor and color of the water, even several miles downstream, is completely unacceptable. Though this stream has not been identified by the Division of Water Quality as "impaired," based on their evaluation, the stream should not have been a Class C stream, protective only of aquatic habitat (and we seriously doubt that this facility has operated in way that protected aquatic habitat for much of its existence) but Class B waters, based on historical uses of the stream for swimming and full immersion baptisms. These uses have been impossible in recent years, but that is no excuse for not requiring permit conditions and enforcement that will protect the public's right to safely use Long Creek in these ways. I am also concerned about the very recent history of repeated reportable non-compliance with the Clean Water Act requirements for the treatment plant's discharge, over the seven most recent quarters. Even one or two quarters imply a facility that needs greater vigilance by state officials and major improvements, but seven quarters indicates a real failure of accountability. In the first and second quarters of this year, the facility was 38% over its mercury discharge limit and 138% over, respectively. This is completely unacceptable, and should result in an immediate state review of all potential sources of this everlasting, cumulative and toxic metal with strong action directly against the responsible parties and action against the Long Creek pre-treatment program for failure to immediately remedy this situation. Two letters of violation have been sent to the facility in the past 4 years for failures in some aspect of handling hazardous or toxic materials (RCRA), which gives me grave concern for the safety of the environment and residents near the facility. Substantial penalties should be assessed for mismanagement of such substances at the plant. Flows for the plant are said to average between 5.8 million gallons/day and 12.0 million gallons/day, a clear sign that there is a very large amount of infiltration into the sewage collection system. As in many municipalities, a lack of oversight, adequate budgeting and enforcement for sewage overflows —such as the one recently observed into Mountain Creek by a resident near New London, have allowed this condition to persist and worsen in an unsustainable manner, at the expense of water quality and residents downstream. The new jail, a significant contributor to wastewater flow in that line, should never have been permitted, knowing the line could not handle even the previous allocated wastewater without overflows. The permit must include a condition that a full assessment of all collection lines must be carried out within 90 days, with an increase in the pace of all needed repairs and upgrades, funded by increased sewer use fees as needed. A moratorium must be established along all sewage collection lines on which overflows have occurred or lines have evidence of more than 10 percent inflow. The higher average monthly flows indicate that this facility is nearing 80% of capacity and would almost certainly reach this level before the next permitting cycle. If the City does not reduce its maximum flows by at least 10% through an aggressive program of repair of its collection lines by two years into the permit, there should be a requirement that the 80% engineering study should be required. It's clear that there's a serious lack of communication between water quality planners who seem to acknowledge that this stream is being impacted by the plant's operations and the monitoring requirements and limits that are proposed in this draft permit. No facility should be permitted to discharge wastewater flows that can be as much as 94% of the stream during drought conditions, but if they are, the permit conditions must be extremely stringent, and enforcement of those conditions must be swift and cause immediate action to remedy the conditions. Basin Planners recommended a reduction in BOD to 5 mg/L during summer months, based on the high percentage of this plant's effluent and the conditions of the stream during the summer of 2003. The permit writer has completely ignored this recommendation and continues with the previous BOD level of 10-mg/L monthly average or 15 mg/L weekly averages. These limits should be lowered to the recommended level, with additional nutrient removal required in order to maintain 5 mg/L to protect the stream. We support the addition of a total residual chlorine limit to this permit to protect the downstream aquatic habitat. Albemarle and Stanly County continue to aggressively recruit new industries with widely varying discharge parameters, so to assume that metals which were found below surface water standards during the past permit cycle will not be a problem in future cycles is not acceptable. All metals previously monitored in this permit must continue to be monitored and specific weekly average limits must be included in the permit. Arsenic, cadmium, lead, nickel and molybdenum should be added with weekly average limits. If there is truly no reason to expect these limits to be exceeded, the facility should have no concerns about including them in the permit, and NC DWQ must have the tools needed to protect water quality. Furthermore, as the potential to exceed analysis indicates that copper, zinc and silver could be above regulatory limits, the monitoring frequency should be increased to at least twice/week, with daily, weekly average and monthly average limits. The facility must also be required to monitor daily for fecal coliform, with a daily limit. If this stream is to become useable again as even a Class C stream (secondary recreation), the public deserves to have access to daily discharges and ambient monitoring for fecal coliform, not simply a geometric mean that minimizes the spikes in bacterial releases that are important to public right to know. Color monitoring should continue and, though it has reduced somewhat, residents still report that the dark color of the stream for miles downstream is a significant reason that they do not trust the water to be safe for swimming, fishing or wading. For all colored discharges, we call for an "acceptable" color standard to be an increase of no more than 100% over the same color (measured at its maximum absorbance value) measured upstream of the discharge. In addition to self -reported discharge monitoring data, the Division of Water Quality should perform at least annual sampling on an unannounced visit to confirm water quality parameters. The permit should also include a summary of the permitted sites for sludge disposal and an assessment of slopes, how close the aquifer is to the surface under high rainfall conditions, and how close the permitted field is to vulnerable surface waters. There should also be a survey of residents in the vicinity of these fields to assure that no unacceptable odors or other conditions (as described under NC 2L "non -discharge" rules) are making these sites unsuitable for sludge spreading. In addition, we object to the use of any "dedicated" sites for spreading of sludge in excess of the rate that can be incorporated by the planted crop. Even with monitoring wells in place, this is like closing the barn door after the horse left the barn; when facilities are allow to risk contamination of groundwater, which is to be protected as a drinking water source. Thank you for your consideration of my comments and concerns about the operation and discharges of the Long Creek Wastewater Treatment Plant and the downstream portion of the Creek. We hope that, with firmer oversight and accountability from the Division of Water Quality, we will soon be able to use the Creek again for family recreation...

O. Box 190 Albemarle, N. C. 28002-0190 DENR - WATER QUALITY POINT SOURCE BRANCH Per the NPDES Permit issuance cover letter dated June 10, 2005, I am requesting that the limits for Cyanide and Selenium be removed from the City of Albemarle WWTP NPDES permit. The City of Albemarle has had twelve consecutive months of Cyanide and Selenium values below detection limits. Twelve DMRs are attached to support this claim. I request that the limits be removed for these parameters and monitoring revert back to Long Term Monitoring Plan frequencies. I would like to also request that the monitoring frequency for Mercury be reduced from weekly to twice per month. This monitoring is quite expensive and is costing the City of Albemarle approximately $10,000 per year.
