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 facility discharges in the Neuse River Basin (NRB). All streams in the NRB have been designated as nutrient sensitive waters (NSW) as a result of algal bloom problems in the estuary. The North Carolina Environmental Management Commission recently adopted rules establishing the Neuse River Basin Nutrient Sensitive Waters Management Strategy for the reduction of phosphorus and nitrogen inputs. The point source rule (15A NCAC 2B.0234) is intended to reduce total nitrogen (TN) discharges by 30% by 2003. An annual limit of 67,580 pounds TN per year has been allocated for your facility. All facilities with permitted flow greater than or equal to 0.5 MGD are receiving a TN limit in this permit cycle. 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. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714).

TOTAL NITROGEN MONITORING The Permittee shall calculate the annual mass loading of total nitrogen as the sum of monthly loadings, according to the following equations: (1) Monthly Mass Loading (lb/mo) = TN x Q x 8.34 where: TN = the average total nitrogen concentration (mg/L) of the composite samples collected during the month Q = the total wastewater flow discharged during the month (MG/mo) 8.34 = conversion factor, from (mg/L x MG) to pounds (2) Annual Mass Loading (lb/yr) = E (Monthly Mass Loadings) for the calendar year The Permittee shall report the total nitrogen concentration for each sample and the monthly mass loading in the appropriate self -monitoring report and the annual mass loading of total nitrogen in the December self - monitoring report for the year. A. (7.) ANNUAL LIMITS FOR TOTAL NITROGEN (a) The Neuse Nutrient Management Strategy rule for point sources (`) provides that annual mass limits for total nitrogen shall be included in the permits for all dischargers with permitted flows (as defined in the Strategy) greater than or equal to 0.5 MGD and that those nitrogen limits, including the limits in this permit, shall become effective with the calendar year beginning on January 1, 2003. (b) The Neuse rule also provides that members of a group compliance association shall not be subject to individual annual mass limits for total nitrogen. At the time of permit issuance, the Permittee had expressed interest in joining such an association. Accordingly, (1) the total nitrogen limit.in Condition A(1) of this permit is deemed waived provided that the following conditions are met: (i) a formal agreement between the association and Environmental Management Commission, as outlined in 15A NCAC 2B. 0234, is established and is in effect; and (ii) the Permittee is a party to said agreement; and (iii) the association and the Permittee substantially conform with the agreement. (2) So long as the total nitrogen limit in Condition A(1) is waived, the group nitrogen allocation established pursuant to the agreement referenced above and any subsequent amendments is hereby incorporated as an enforceable part of this permit. (c) If the Division determines, at any time during the term of this permit, that these conditions are not being met, it shall notify the Permittee in writing of this determination and of its basis. The consequence of such a determination shall be that the Permittee's annual mass limit for total nitrogen and its effective date shall be reinstated immediately. The Division shall accept and consider written responses received from the Permittee and/or the association within thirty (30) days of the original notice before making a final decision and will provide that decision in writing. (c) The Permittee shall notify the Division in writing within five (5) working days if, at any time during the term of this permit, the Permittee elects not to join the association, or if it withdraws or otherwise loses its membership in the association. Notification shall be sent to: NC DENR / Division of Water Quality / NPDES Unit 1617 Mail Service Center Raleigh, NC 27699-1617 Footnote: Neuse River Basin -Nutrient Sensitive Waters Management Strategy: Wastewater Discharge Requirements (15A NCAC 2B. 0234). Permit Number: NC0066516. A. (8.) CHRONIC TO`ZICITY PERMIT LIMIT (QRTRLY) 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, 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 facility is permitted for flows of 0.5, 2.0, 4.0, and 6.0 MGD. The 1999 yearly average flow was 0.1351, therefore the facility is operating according to the 0.5 MGD effluent limitations and monitoring page. Flow from the treatment plant is discharged through one outfall to Terrible Creek. Sludge is aerobically digested and thickened prior to being land applied according to permit WQ0000506. In October 1999, the facility received an Authorization to Construct (ATC) for the construction of a 0.5 MGD treatment train. This will increase the design capacity of the treatment system to 1.0 MGD. The Town serves a population of 1,000 - 5,000, with 73% of the total flow being domestic wastewater. The remaining 27% of the flow is comprised of industrial wastewater. The facility has a modified pretreatment program and has sampled four times over the last five years for the following toxicants: As, Cd, Cr, Cu, Pb, Hg, Mo, Ni, Se, Zn.

November 22, 1999 — NOV issued for failure of toxicity testing in September 1999. November 3, 1999 — NOV issued in response to October 14, 1999 Compliance Inspection Evaluation. Reasonable Potential Review Copper — December 1999 discharge monitoring report (DMR) reports a concentration 11.0 µg/1 of copper for the effluent sampled on December 1, 1999. The in -stream waste concentration is 100% for this facility. Since the reported value is greater than the action level for copper (7 µg/L) reasonable potential has been established. NC DWQ policy states that if a facility has a reasonable potential to exceed an "action" level, that monitoring with'no limit is appropriate. Lead — According to the reasonable potential using the last two years of DMR data there is not reasonable potential for the facility to exceed the allowable concentration for lead. A lead limit is not appropriate. Since the facility's pretreatment program is a modified program monitoring is relatively infrequent. Therefore, it is recommended that lead monitoring remain as a condition for the permit. Zinc — The June 1999 DMR reports a concentration of 81 µg/L for Zinc. The action level for zinc is 50 µg/L. Therefore, reasonable potential exist for the facility to exceed the allowable concentration for zinc (IWC = 100%). NC DWQ policy states that if a facility has a reasonable potential to exceed an "action" level, that monitoring with no limit is appropriate. Arsenic — Only four data points are available, with all being below the detection limit of 0.005 mg/L. No reasonable potential exist. Cadmium - Only four data points are available, with all being below the detection limit of 0.001 mg/L. No reasonable potential exist. Chromium - Only four data points are available, with all being below the detection limit of 0.005 mg/L. No reasonable potential exist. Mercury - Only four data points are available, with all being below the detection limit of 0:0002 mg/L. No reasonable potential exist. Molybdenum - Only four data points are available, with three being below the detection limit of 0.005 mg/L and one detection of 0.09 mg/L. Nickel - Only four data points are available, with all being belowthe detection limit of 0.01 mg/L. No reasonable potential exist. . Selenium'- Only four data points are available, with all being below the detection limit of 0.002 mg/L. No reasonable potential exist. Basin Plan Review A nutrient management strategy is being implemented into this permit, according to current Division procedure. The Neuse River at the discharge location is not listed on the state's 303(d) list.. There is one comprehensive ambient monitoring station in subbasin 03-04-03. The station is located on Middle Creek at highway 50 near Clayton. The overall use support rating for this station is Support Threatened. With the potential sources coming from both point and non -point contributors. There'is one Benthic site downstream of Fuquay- Varina, which received a good -fair rating. Terrible Creek discharges into Middle Creek and the comprehensive site is,located approximately 9 miles downstream of the confluence of Middle Creek and Terrible Creek. General Comments Chronic Toxicity results show periodic failures of toxicity, four failures over the last four years. Three of the four failures occurred in consecutive months in 1997. It would appear that the toxicity problem was identified and removed. The facility passed the subsequent toxicity test until one failure in September 1998. The plant would appear to well operated. Ammonia toxicity will not be calculated since the facility already has an ammonia limit of 2.0 mg/L. It is recommended that the permit be renewed with existing limitations, according to the Nutrient Management Strategy.

Spray Irrigation: Connection to Regional Sewer System: Subsurface: Other disposal options: 5. Other Special Items: The Raleigh Regional Office has reviewed the current submittal package requesting an NPDES discharge permit renewal for the Fuquay-Varina WWTP (Terrible Creek). Our staff has reviewed our files of the above referenced site, and performed a site visit, in order to make the following comments and recommendations for the request. The earliest permit on record in our office became effective December 2,1991, and was issued for 6.0 MGD (with effluent sheets for 2.0 and 4.0 MGD). The permit was modified on December 11,1991, and reissued on April 1,1994 with modifications including an additional effluent sheet for 0.5 MGD. An authorization to construct a 0.5 MGD plant was issued on June 30, 1994. Another modification to the permit became effective September 1, 1996. I believe that the facility was started up in early summer of 1996. The inspection was performed by Charles Brown of our staff on June 5,1998. His summary letter of the inspection is included. His comments involved the D.O. meter, pH control, and I/I activities. The DMRs indicate that the ORC is only on site an average of 3 days a week, while the facility classification (class III) requires the ORC to be on site 5 days a week. A letter will be sent to the permittee asking for clarification. A review of the records from the time frame of his inspection letter to the most recent data available shows no permit limit or monitoring violations. The treatment plant did, however, receive a NOV/Notice of Intent to Recommend Enforcement Action for an illegal bypass of their treatment facility on Apra 23, 1998. One final note pertaining to residuals disposal. Records indicate that this facility is covered under permit WQ0000506 for land disposal, however, a review of that permit (May 8,1998) does not indicate the Fuquay-Varina WWTP (Terrible Creek) as a permitted source. The other Fuquay-Varina WWTP (Kenneth Creek (NC0028118)) is indicated as a source. This discrepancy should probably be investigated by ME staff. Non -Discharge Staff Report Page 4 Based on the above, the RRO recommends that the subject project be awarded ad discharge permit renewal as requested, pending ME satisfaction of all requirements.

By this letter, the DEHNR is waiving the instream monitoring requirements as specified within your individual NPDES permit beginning December 1, 1994and at such time that the LNBA begins collection and analysis of the water quality monitoring as specified in the Memorandum of Agreement (MOA) signed by this agency and the LNBA, dated July 26,1994. The agreement identifies the stations, parametric coverage and frequency of analysis required of the LNBA in order that the instream monitoring requirements be waived. All other terms and conditions in the original permit remain unchanged and in full effect. These modifications are 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 December 6,1983. Should your membership in the LNBA be terminated, you shall notify the Division immediately and the instream monitoring requirements given in your permit prior to December 1,1994 will be reinstated. I would like to express my appreciation for the cooperation and participation of all members of the LNBA in this innovative approach to environmental monitoring. It is expected that the results of the agreement will effectively contribute to our understanding of the lower Neuse basin environment. We have designated Ken Eagleson as our primary contact for issues related to the MOA. He can be reached at (919) 733-9960. We also look forward to the advances that this cooperative agreement will provide in our management of the lower Neuse and ask that you feel free to contact us should any questions arise regarding the monitoring efforts or interpretations of the information collected. We will be maintaining our own series of monitoring stations in the lower Neuse which when added to the P.O.
