Sexton, Water Resources Superintendent County of Brunswick Public Utilities Department PO Box 249 Bolivia, North Carolina 28422 Dear Mr. Sexton: ROY COOPER Governor MICHAEL S. REGAN Secretary S. JAY ZIMMERMAN Director Subject: Draft NPDES Permit NCO040061 Beaverdam Creek WTP — PC -1 4305 Southport Supply Hwy SE, Southport 28461 Brunswick County In response to your request to renew the subject NPDES permit, the Division of Water Resources (DWR or the Division) hereby transmits this draft for your review and comment. Please review this document to assure your understanding of the permit limits and monitoring conditions, and to correct errors, if any. The Division understands that you have made no significant changes to your facility since the last permit, renewal. We have made the following updates to your previous permit: 1. The facility map has been updated. 2. Regulatory citations have been added. 3. Total Manganese monitoring has been removed because the EPA approved removal of NC aquatic life standard as part of 2007-2016 Triennial review. Therefore, there are no limits to compare monitoring data for this parameter. 4. In accordance with established freshwater standards for turbidity, a monthly average limit of 25 NTU and a daily maximum limit of 25 NTU have been added with the following footnote: ➢ Turbidity - Effluent turbidity shall not cause receiving -stream turbidity to exceed 25 NTU. If background turbidity naturally exceeds 25 NTU, the effluent shall not cause background turbidity to increase. Any discharge exceeding this permit limit will require sufficient instream sampling (upstream and/or downstream) to verify compliance (effluent vs. background). [NCAC 02B. 0220(19)] 5. Effluent and upstream quarterly monitoring for Total Hardness has been added. 6. The engineering evaluation of a Bio -Solids Management Plan (BSMP) has been removed for this permit renewal. 7. Electronic reporting of discharge monitoring reports (eDMR) has been added in Section A. (3.). Concurrent with this notification, the Division will solicit public comment on this draft by publishing a notice in newspapers having circulation in the general Brunwick County area, as required by the NPDES Program. Please provide your comments, if any, to me via email [derek.denard@ncdenr.gov] or write to my attention care of DEQ / DWR / NPDES Program no later than September 8, 2017.

ACUTE TOXICITY - MONITORING ONLY (QUARTERLY) [15A NCAC 02B .0500 et seq.] The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent Concentration" (Revised -December 2010 or subsequent versions). The monitoring shall be performed as a Mysid Shrimp (Mysidopsis bahia) 24 hour static test. The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure document).. The tests will be performed during the months of January, April, July and October. These months signify the first month of each three month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR -1) for the month in which it was performed, using.the parameter code TGE3E. Additionally, DWR Form AT -2 (original) is to be sent to the following addiess: Attention: North Carolina Division of Water Resources Water Sciences Section/A4uatic Toxicology Branch 1621 Mail Service Center Raleigh,_NC 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Water 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' and accurate and include all supporting,chemical/physical measurements performed in association with the toxicity tests, as,,well as all dose/response data. 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 facilityname, 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 Water Sciences Section at the address'cited above. Should the pprmittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring will begin` immediately. Upon submission of a valid test, this monthly test requirement will revert to quarterly in the months specified above. Should any test data from either these monitoring requirements or tests performed by the North Carolina Division of Water Resources 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 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. Page 7 of 11 NPDES Permit NCO040061 A. (3.) ACUTE TOXICITY - MONITORING ONLY (QUARTERLY), continued USE OF A DIFFERENT TEST ORGANISM The Permittee may request the use of a different test organism upon documentation that the alternate test organism would provide an equal or greater level of protection and is appropriate based on the characteristics of the discharge and receiving stream. Such documentation would consist of one of the following: 1. For saltwater classified streams, a fathead minnow may be assigned as the acute testing species if the salinity of the receiving stream at the point of discharge is <5 ppt throughout the tidally influenced cycle. This determination may be based on the best professional judgment of DWR staff or data collection provided by the Permittee and approved by DWR staff. This evaluation should include vertical profiles of salinity/conductivity measurements at both high tide and low tide over several 24 hr cycles. 2. Three consecutive "side-by-side" tests with results indicating that the alternate test organism is as or more sensitive to the facility's effluent. Each test series would consist of two separate toxicity tests conducted on the same sample of effluent with the length of exposure specified by the permit, the only difference between the tests being the organism used. 3. An alternate plan developed by the Permittee and approved by the Aquatic Toxicology Branch that demonstrates an equal level of protection is offered by the test organism. For items 2 and 3, it must also be demonstrated that viable and standardized culture techniques are available for that organism and standardized testing methodologies have been developed and validated. This demonstration should meet guidance provided by EPA in Section 6 of EPA -821-R-02-012, Short Term Methods for Estimating the Acute Toxicity of Effluents and Receiving Waters to Freshwater Organisms, Fifth Edition, 2002. Requests to use a different test organism and supporting documentation should be sent to NC DWR, Water Sciences Section/Aquatic Toxicology Branch at the address listed above. A. (4.) PERMIT RE-OPERNER: ADJUST WET -TEST SPECIES [G. S. 143-215.1(b)] The Division may reopen this permit to alter or replace Whole Effluent Toxicity (WET) test procedures or test species as future regulations, environmental conditions, or site conditions may warrant. A. (5.) PERMIT RE -OPENER: TMDL IMPLEMENTATION [G.S. 143-215.1(b)] The Division may, upon written notification to the Permittee, re -open this permit in order to incorporate or modify effluent limits, monitoring and reporting requirements, and other permit conditions when it deems such action is necessary to implement TMDL(s) approved by the USEPA. Page 8 of 11 NPDES Permit NCO040061 A. (6.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015 NOTE This special condition supplements or supersedes the following sections within Part H of this permit (Standard Conditions for NPDES Permits) • Section B (11 ) • Section D. (2 ) • Section D. (6 ) • Section E (5 ) Signatory Requirements Reporting Records Retention Monitoring Reports 1. Reporting Requirements (Supersedes Section D. (2.) and Section E. (5.) (a)1 The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ / Division of Water Resources / Water Quality Permitting Section ATTENTION Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1 1, 2, 3) or alternative forms approved by the Director Duplicate signed copies shall be submitted to the mailing address above See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge Starting on December 21, 2020, the permittee must electronically report the following compliance monitoring data and reports, when applicable. Sewer Overflow/Bypass Event Reports, Pretreatment Program Annual Reports; and Clean Water Act (CWA) Section 316(b) Annual Reports. The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver from Electronic Reporting" section below) Page 9 of 11 NPDES Permit NC0040061 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)]. EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well Information on EPA's,NPDES Electronic Reporting Rule is found at: http Hwww2.epa.gov/compliance/final-national-pollutant-discharge-elimination-system-npdes-electronic- reporting-rule Electronic submissions must start by the dates listed in.the "Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Reporting The permittee may seek a temporary elecironid reporting waiver from the Division. To obtain an electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports. The durati6n of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective. Information onf eDMR and the.application for a temporary electronic reporting waiver are found on the following web page: http://deq.ne.gov/about/divisions/wat'&r-resources/edmr 4. minatory Requirements [Supplements Section B.
