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 includes the following changes from your current permit ➢ Daily maximum limits for cadmium and mercury have been deleted from this permit because the toxicants presented no reasonable potential to exceed water quality standards based on statistical analysis of the effluent data ➢ Monitoring frequencies for cadmium nickel and silver have been deleted Monitoring of cadmium and nickel shall continue in the LTMP ➢ Monitoring frequency for mercury has been reduced to 2/month because there is no limit for this parameter in the permit ➢ The daily maximum limit for lead has been changed to 33 8 ug/l because the previous limit was wrong ➢ To support nutrient -sensitive modeling for the Deep River Cape Fear watershed, the Division now requires permit re -opener language for supplementary nutrient monitoring to be added to the permit If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adludicatory hearing upon written

INTRODUCTION The City of Randleman Wastewater Treatment Plant (W WTP), herein called Randleman or the pennittee, requires a National Pollutant Discharge Elimination System (NPDES) permit to discharge treated wastewater to the waters of the state The pernittee's 5-year NPDES permit expired at midnight on August 31, 2006 and have requested renewal from the Division of Water Quality This Fact Sheet summanzes background information and rationale used by the Division's NPDES Unit to determine permit limits and monitonng frequencies FACILITY DESCRIPTION Randleman is a publicly owned treatment works (POTW) utilizing a Grade III aeration units and clarifiers to treat domestic and industrial wastewater The treatment system utilizes a mechanical bar screen, grit removal device, four clarifiers, four extended aeration basins, chlorine contact chamber, cascade aerator, dechlonnation, traveling filter bridge and three aerobic digesters Table 1 Summarizes the receiving stream characteristics and facility description The previous pennrt had incorrect 30Q2 stream flow value in the fact sheet Table 1 City of Randleman W WTP Facility Information Applicant/Facility Name City of Randleman /

NPDES Permit NCO025445 Page 1 within the range of 88 — 1 23 MGD as reported in the Discharge Monitoring Report (DMR) The permittee is a member of the Cape Fear Monitoring Coalition, and all its in -stream monitoring is conditionally waived for the duration of its membership in the Coalition The stream flow characteristics will probably change due to the minimum release requirement of the Randleman Lake dam Since this information is not yet available, the existing flow characteristics will be used for this permit renewal When the dam is fully operational, the permit limits may be adjusted during renewal Randleman has two significant industrial users (23% of the total flow) and a full-scale pretreatment program The permit will continue to require the City of Randleman to implement its pretreatment program BASINWIDE PLAN Deep River [17-(10 5) b] from US 220 to Subbasm boundary (2 2 miles) is supporting aquatic life because no criteria were exceeded at site BA301 (Cape Fear River Basmwide Water Quality Plan, 2005) The Division added High Point Lake to the 2006 303(d) list due to violations of the chlorophyll a standard, and we expect that the new Randleman Reservoir will have similar violations soon after it is filled The Modeling Unit has not yet scheduled stream studies in this part of the river basin, but it is possible that work could begin soon (Supplement to NPDES Permitting Strategies Cape Fear River Basin, 2006) Until stream studies are scheduled and prompt increased monitoring, existing nutrient requirements in this sub -watershed will continue unchanged That is, dischargers will monitor nutrients at the frequencies set in their existing permits, which should be consistent with those in the 2B 0508 rule The permit will include a re -opener Special Condition allowing the Division to incorporate monitoring requirements or other conditions during this permit term if necessary to support water quality studies The language of the re -opener clause will be "The Division may, upon written notification to the Permittee, require additional effluent monitoring that it deems necessary to support its water quality protection and restoration efforts in the receiving stream" (Supplement to NPDES Permitting Strategies Cape Fear River Basin, 2006) WASTE LOAD ALLOCATION (WLA) The last waste load allocation was done in 1995 and developed effluent limits and monitoring requirements for BOD, ammonia and TSS, considering an in -stream waste concentration (IWC) of 35 % at 1 745 MGD The Division views these limits and monitoring requirements appropriate for renewal 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 NCO025445 Page 2 TRC A TRC limit of 28 ug/l will be continued in this permit to be consistent with the Division's TRC policy REASONABLE PO rENTIAL ANALYSIS (RPA) To establish a list of pollutants of concern (POCs), the Division examined Randleman's permit application, pretreatment data, two years of Discharge Monitoring Reports (January 2004 through August 2006), and the basin plan The Division then applied the reasonable potential analysts to calculate a maximum predicted concentration for each POC Each maximum predicted concentration was then compared to the POC's freshwater standard/cntenon or allowable concentration considering dilution If by this method, a POC showed reasonable potential to exceed its standard or critenon, 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 Reasonable potential analysis was performed for cadmium, chromium, copper, cyanide, fluonde, lead, mercury, nickel, silver and zinc Cadmium -The maximum predicted concentration is less than the allowable concentration The limit and monitoring are deleted from this permit Monitoring should continue in the LTMP Chromium — The maximum predicted concentration is less than the allowable concentration Continue with 2/month monitoring Copper — The maximum predicted concentration is greater than the allowable concentration This is an action level parameter, monitoring will continue 2/month Cyanide - The maximum predicted concentration is less than the allowable concentration Continue with 2/month monitonng Fluoride - The maximum predicted concentration is less than the allowable concentration Continue with 2/month monitoring Lead - The maximum predicted concentration is greater than the allowable concentration Daily maximum limit of 33 8 ug/i and weekly monitoring is recommended The previous permit had a wrong limit for total lead Mercury - The maximum predicted concentration is less than the allowable concentration The limit is deleted from this permit Monitoring is reduced to 2/month Nickel - The maximum predicted concentration is less than the allowable concentration Momtonng is deleted from this permit Monitoring should continue in the LTMP Silver - The maximum predicted concentration is greater than the allowable concentration Monitoring is deleted from this permit because there is no detection in the sixty data set Fact Sheet Renewal - NPDES NC0025445 Page 3 Zinc -

If so, what were the results? If not why?

The flow goes through the outside part or "doughnut" of the tank, then enters the center clarifier where the sludge settles, and is returned to the head of the plant via the RAS pump station. The effluent from the clarifier enters the chlorine contact basin, then into the traveling filter bridge. At the end of the filter the water is dechlor►nated and then flows into Deep River. Each day sludge is wasted to a sludge basin. When a basin is filled, it is then limed and when ready, is hauled to the state approved fields.
