Hunt, Jr., Governor Bill Holman, Secretary Kerr T. Stevens, Director November 29, 1999 Mr. Leonard Green Town of Parkton P.O. Box 55 Parkton, North Carolina 28371 A2M • NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES Subject: Issuance of NPDES Permit NCO026921 Parkton WWTP Robeson County Dear Mr. Green: The Division received your application for a wastewater discharge permit on June 29, 1999. Division personnel have reviewed and approved your application. 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 December 6, 1983, and as subsequently amended. There are currently 11 streams in the Lumber River Basin that have fish consumption advisories for mercury, and appear as impaired waters on the North Carolina 1998 303(d) list. In order to evaluate the relative contribution of mercury from NPDES point source discharges, mercury monitoring of effluent and sludge has been added to this permit. This data will then be used to develop a mercury management strategy, by allocating allowable mercury loads to known sources (both point and nonpoint). The ultimate goal of the mercury management strategy is to reduce mercury concentrations in fish tissue and eliminate the need for fish - consumption advisories in this basin. 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, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, this decision shall be final and binding. Please note that this permit is not transferable except after notice to the Division. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be required. If you have any questions concerning this permit, please contact Charles Weaver at telephone number (919) 733-5083, extension 511. cc: Central Files Fayetteville Regional Office/Water Quality Section NPDES 1Triits Point Source Compliance Enforcement Unit Aquatic Toxicology Unit 1617 Mail Service Center, Raleigh, Norlh Carolina 27699-1617 An Equal Opportunity Affirmative Action Employer Sincerely, Original Signed By David A.

The analytical detection limit for mercury samples is 0.2 µg/L. There shall be no discharge of floating solids or visible foam in other than trace amounts. Permit NCO026921 A. (2.) 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 January, April, July & October. 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: 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 mouth 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.

"Upset ".means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does -not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of.preventive maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense .to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph c. of this condition are met. No determination made during. administrative review of claims that noncompliance was caused by upset, .and before an action for noncompliance, is final administrative action subject to judicial review. c. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of, upset shall. demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the cause(s) of the upset; (2) The permittee facility was at the time being -properly operated; and (3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit. . (4) The per ' ittee complied with any remedial measures required under Part I1, B. 2. of this permit. d. Burden of proof. In any enforcement proceeding the permittee seeking to establish. the occurrence of'an upset has the burden of proof. 6. Removed Substances Solid's; sludges, filter backwash, or other' pollutants removed. in, the course of treatment or control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and, in 'a manner such as to prevent any pollutant from such materials from entering waters of the State or navigable waters of the United States.- The permittee..shall comply.,with all .existing federal regulations. governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued by the Permit Issuing Authority -for the utilization/disposal of sludge may be reopened and modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The applicable 40 CFR Part 503, Stand.forihe. permitt- shall comply with Standards Use and Disposal of Sewage`Sludge.(when promulgated) within the.time provided in. the regulation, even if the permit is not modified to incorporate the requirement. The permittee shall notify the. Permit Issuing Authority of any significant change in its sludge use or disposal practices.

The 303(d) process requires that a TMDL be developed for each of the listed waters, in order to allocate allowable mercury loads to known sources. The ultimate objective is to reduce fish tissue mercury concentrations and eliminate the need for fish -consumption advisories in this basin. In order for DWQ to complete the TMDL study, permit writers will need to incorporate mercury monitoring into the NPDES permits listed below. Please contact me with any questions. Thanks. Facilities Needing Mercury Effluent Limits. Based on existing effluent data, the facilities listed below will receive effluent limits of 0.012 ug/1 for total mercury (with 0.2 ug/I detection limit for compliance), with effluent monitoring frequency based on facility class. Permit Writer • NC0025577-Red Springs Belnick • NC0021920-Whiteville Belnick Facilities Needing Monitoring Only. There is insufficient or no data to determine whether the following facilities are a mercury source. Therefore, the facilities listed below will receive quarterly effluent monitoring for total mercury (specify a 0.2 ug/I detection limit), and semi-annual monitoring of sludge (specify a 0.1 mg/kg detection limit, dry weight basis).

Upon review of these drafts, we noted that Condition A(2) contains chronic toxicity language that EPA has stated they will not approve in permits. The first sentence in Condition A(2) which contains the language, "The effluent discharge shall not exhibit a three- month arithmetic average..." is incorrect. Please note in the third paragraph, the sentence that states "the average chronic value from these follow-up multiple -concentration analyses will establish compliance with the permit limit" is incorrect as well. As per discussions with EPA, this language cannot be used in permits with chronic toxicity limits. The use of this incorrect language was addressed in a previous memo to your office dated September 13, 1999. Apparently, this QCL Version that was disapproved by EPA still exists either on individual permit writer desktops or on the Water Quality Server. This language should be removed to avoid using it in future permits. Attached to this memo is a copy of a July 19, 1999 email that Kevin Bowden sent to you which attached toxicity language for the four main toxicity tests that are used in NPDES permits. One of these was the EPA approved quarterly chronic limit language. Please find attached a copy of the correct toxicity test condition language that should be incorporated into these two draft permits. We appreciate the opportunity to provide comment prior to final permit issuance. If you have any questions, please contact me or Kristie Robeson at 733-2136. cc: Charles Weaver-NPDES Permits Unit Shannon Langley -Point Source Compliance/Enforcement Unit Paul Rawls -Fayetteville Regional Office Aquatic Toxicology Unit Files Kristie Robeson Central Files Subject: "Final" Tox Language Date: Mon, 19 Jul 1999 11:03:36 -0400 From: Key1in Bowden<kevin_bowden@h2o.enr.state.nc.us> To: Mark McIntire <mark mcintire@h2o.enr.state.nc.us>, Dave Goodrich <dave—goodrichC h2o.enr.state.nc.us> CC: Charles Weaver<charIes_weaver@h2o.enr.state.nc.us>, Susan Wilson <Susan wilson@h2o.enr.state.nc.us> Matt Matthews <matt matthews@h2o.enr.state.nc.us> Kristie Robeson <kristie rbeson@h2o.enr.state.nc.us> Mark, Please find attached toxicity test condition language which the majority of effluent discharge situations encounteredo should coves basis.

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 U Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of . 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 U Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value forj 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 U 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: Environmental Sciences Branch North Carolina Division of Water Quality 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.
