REGAN Secretary Water Resources LINDA CULPEPPER Environmental Quality Interim Director June 27,2018 Mr.Timothy Buck,County Manager Pamlico County Water System P.O.Box 158 Bayboro,NC 28515-0158 Subject: Draft NPDES Permit NC0088340 Mill Pond WTP(PC-1) Pamlico County Dear Mr. Buck: 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. Concurrent sampling with quarterly WET testing is no longer required for toxicants. 4. Total Manganese monitoring has been removed because the EPA approved removal of this NC aquatic life standard as part of 2007-2016 Triennial review.Therefore,there are no limits to compare monitoring data for this parameter. 5. Per the terms of your previous NPDES permit found in Part I, Condition A. (4.),you were required to submit a Discharge Alternatives Evaluation to the Division along with the submission of the next permit renewal application due 6 months prior to permit expiration on June 1,2017.Non-compliance with this permit condition resulted in the March 29,2018 Notice of Violation(NOV-2018-PC-0107). Although,this facility now has a record of passing Whole Effluent Toxicity(WET)testing,the Discharge Alternatives Evaluation has been renewed in Part I,Condition A.(3.).The Discharge Alternatives Evaluation included for this permit renewal will be due approximately 48 months from the permit effective date. 6. The NC 2007-2014 Water Quality Standard(WQS)Triennial Review was approved by the NC Environmental Management Committee(EMC)on November 13,2014.The US EPA subsequently approved the WQS revisions on April 6,2016 with some exceptions.The NC Division of Water Resources NPDES Permitting Unit is required to implement the new dissolved metal standards in all permits public noticed after April 6,2016.A reasonable potential analysis of data indicated that limits are needed for Total Zinc based the new dissolved metal standards.The following limits have been applied for this permit renewal with monthly monitoring: State of North Carolina I Environmental Quality 1617 Mail Service Center I Raleigh,North Carolina 27699-1617 919-707-9000 Mr.Buck June 27,2018 Page 2 of 3 Parameter Monthly Average Limit Daily Maximum Limit Zinc 85.614/L 95.1 µg/L 7. A compliance schedule has been added for Total Zinc limits in Section A. (2.).The Total Zinc limits will become effective 48 months from the effective date of the permit. 8. Total Copper data was reported as< 10 µg/L.Therefore,Total Copper has not been given a limit. However,monthly monitoring has been maintained for the renewal because the dissolved metals standards for Copper are less than 10 µg/L.For Copper,the dissolved metals standards for saltwater are 3.70 µg/L for the Chronic value and 5.80 µg/L for the Acute value.Please note that the analytical method Practical Quantitation Limit(PQL)for Total Copper should be at least 2 µg/1 to demonstrate compliance with dissolved metals standards.Minimum detection and reporting levels(MDLs ,PQLs) are defined by our Water Sciences Section as follows: Each analytical procedure has a Practical Quantitation Limit(PQL),which is defmed as"the lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions."PQLs are subjectively set at some multiple of typical Method Detection Limits(MDLs)for reagent water(generally 3 to 5 times the MDL).The PQL for a procedure may also be defmed by: a reporting limit or minimum limit (ML)specified by the analytical method; sample volume and buret graduations; and/or minimum measurement values that are method-defined.The established PQL for a procedure serves as a reliable and routinely achievable reporting limit for a biological or chemical parameter (https://deq.nc.gov/about/divisions/water-resources/water-resources-data/water-sciences-home- page/microbiology-inorganics-branch/methods-pqls-qa). In accordance with NPDES Standard Conditions Part II Section D.4.,the following is required for test procedures: To meet the intent of the monitoring required by this permit, all test procedures must produce minimum detection and reporting levels that are below the permit discharge requirements and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. If no approved methods are determined capable of achieving minimum detection and reporting levels below permit discharge requirements,then the most sensitive(method with the lowest possible detection and reporting level)approved method must be used. Concurrent with this notification,the Division will solicit public comment on this draft by publishing a notice in newspapers having circulation in the general Pamlico 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 July 27,2018.Your written comments are welcome but not mandatory.Following the mandatory 30-day public comment period,the Division will review all pertinent comments on your permit draft, and take appropriate action prior to issuing your NPDES permit final. Mr.Buck June 27,2018 Page 3 of 3 If you have questions concerning this draft,please e-mail me or call my direct line(919) 807-6307.

DISCHARGE ALTERNATIVES EVALUATION [G.S. 143-215.1(b), 15A NCAC 02H .0105] The Permittee shall assess potential alternatives to eliminate Whole Effluent Toxicity(WET)test failures. This evaluation shall assess the feasibility of all the following alternatives. 1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater treatment plant. Approval or disapproval the plant operator should be acquired. 2. Obtain a Non-discharge permit: Eliminate the surface w = . scharge by obtaining a non-discharge permit for spray irrigation, infiltrate• bsurface disposal (on-site drainfield, infiltration gallery, injection well 3. Install Wastewater Treatment: Install improved was -water tr- - t to enable the facility effluent to consistently pass the WET test.If this is not tec . ly feasible or cost prohibitive, please explain and provide estimated costs. 4. Use Alternative Water Treatment Source:Obtain drinking water from another source(nearest County, City, or Town or other wells) so thedischarge or toxicity problem is eliminated. 5. Use Alternative Water Treatment t:; u d: Install alternative and/or innovative water treatment methods or operational improvements that do not produce toxic wastewaters. For example, install a recycle iron/manganese filtration system with no discharge or combine discharge with WWTP or cooling water effluents. 6. Discharge to a Larger waterbodv/Perform a dilution model: Relocate the facility's discharge to a larger receiving waterbody to eliminate or reduce toxic impacts to the receiving waterbody given the increased dilution. If applicable,perform a dilution model to receive allowance for stream dilution in WET test. 7. Combination of Alternatives: Employ any combination of the alternatives listed above that would result in eliminating or decrease`toxicity until a more feasible solution becomes available. The evaluation shall include a present value of costs analysis for all technologically feasible options as outlined in the Division's"Engineering Alternatives Analysis Guidance Document."This Document can be found at: httpa,pot taLncdenr.org/web/wq/swp/ps/npdes/permits. This evaluation is being requested to determine whether there are any economical and technologically feasible alternatives available to the Permittee to address aquatic toxicity in the plant effluent. Based upon the evaluation, please identify viable alternatives and present an implementation schedule and project timeline for the preferred alternative. The Permittee shall submit the Discharge Alternatives Evaluation to the Division on , [approximately 48 months from the permit effective date] to: NC DEQ/Division of Water Resources/Water Quality Permitting NPDES, Wastewater Branch 1617 Mail Service Center, Raleigh,NC 27699-1617 Page 5 of 9 NPDES Permit NC0088340 A. (4.) ACUTE TOXICITY PASS/FAIL MONITORING (QUARTERLY) [15A NCAC 02B .0500 et seq.] The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defmed 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%(defmed as treatment two in the procedure document).The tests will be performed during the months of March,June,September and December.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 address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh,North Carolina 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 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 Water Sciences Section at the address cited above. Should the permittee 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 6 of 9 NPDES Permit NC0088340 A. (5.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [G.S. 143-215.1(b)] Federal regulations require electronic submittal of all discharge monitoring reports(DMRs)and program reports. The fmal 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 II of this permit (Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D. (2.) Reporting • Section D. (6.) Records Retention • Section E. (5.) 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)intemet 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 7 of 9 NPDES Permit NC0088340 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://www2.epa.gov/compliance/final-national pollutant-discharge-elimination-system-npdes-electronic- reporting-rule.
