REGAN _V, .S�C(Y'P[(il"1 •ti LINDA CULPEPPER NORTH CAROLINA Environmental Quality August 21, 2019 Mr. Brian Alligood Beaufort County 121 West Third Street Washington, NC 27889 Subject: Draft NPDES Permit NC0084808 Richland WTP Grade I Physical Chemical WPCS Beaufort County Dear Mr. Alligood: The Division has reviewed your request to renew the subject permit. Please review this draft carefully to ensure your thorough understanding of the information, conditions, and requirements it contains. The draft permit includes the following significant changes from the existing permit: 1. Language has been updated in Sections A. (1) and A. (6) to require electronic submission of effluent data. Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). 2. Regulatory citations have been added to the permit. 3. Outfall map has been updated. 4. Receiving stream characteristics have been updated on the Supplement to Permit Cover Sheet and a components list has been added. 5. The facility grade has been added in Section A. (1). 6. Monitoring for flow has been changed to continuous in Section A. (1)per the current water treatment plant guidance. 7. The units for salinity were changed from mg/L to ppth in Section A. (1). 8. Monitoring for temperature has been removed in Section A. (1) per the current water treatment plant guidance. 9. Instream monitoring for salinity, conductivity, pH, and DO have been added in Section A. (1) per the current water treatment plant strategy. 10. The effluent sample type for conductivity, salinity, and total nitrogen has been changed to composite in Section A. (1)per the current water treatment plant strategy. 11. Limits for Total Copper and Total Zinc have been added and monitoring increased to monthly in Section A. (1)based a reasonable potential to exceed water quality standards. A compliance schedule has been added as Section A. (3). rk-M North Carolina Department of Environmental Quality I Division of Water Resources 1617 Mail Service Center I Raleigh,North Carolina 27699-1617 919-707-9000 12. Monitoring for ammonia nitrogen has been increased to monthly in Section A. (1) per the current water treatment plant strategy. 13. Footnotes have been updated in Section A. (1). 14. Toxicity test language has been updated in Section A. (2). 15. A discharge alternatives analysis has been added as Section A. (3)to address toxicity failures. Please note that the practical quantitation limit(PQL) for Total Copper is 2 µg/L and the PQL for Total Zinc is 10 µg/L(per the Inorganic Chemistry Branch of the Division of Water Resources Water Sciences Section) and monitoring data should be reportable down to these levels. Limits for water treatment plants are determined by evaluating DMR data submitted to the Division, along with a dilution factor(if applicable) and the maximum monthly average flow reported in the previous 3 years at the time the review is completed. Whole Effluent Toxicity test results submitted during the past three years have demonstrated that the Water Treatment Plant's effluent is showing potential for causing aquatic toxicity in the receiving stream. As a result, Beaufort County shall perform a Discharge Alternatives Evaluation as described in Section A. (3) of this permit. This evaluation is being requested to determine whether there are any economical and technologically feasible alternatives available to Beaufort County to comply with all NC Water Quality Standards. The permittee will be given approximately one permit cycle to evaluate and document possible treatment/discharge alternatives to eliminate aquatic toxicity. The evaluation shall be submitted with the permittee's next permit renewal application and will be carefully reviewed by the Division and the results will be used in the development of a compliance schedule or possible variance request for Beaufort County. 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. The new standards for most metals include acute standards. Further, the freshwater standards for several metals are expressed as the dissolved form of the metals, and seven metals have hardness-dependent equations. As a result, the NPDES Permitting Unit will need site-specific effluent hardness data and instream hardness data,upstream of the discharge, for each facility monitoring these metals in order to calculate permit limitations. Effluent hardness and instream hardness sampling,upstream of the discharge, has been added to this permit at a monitoring frequency of quarterly. See Section A. (1) Effluent Limitations and Monitoring Requirements. � With this notification,the Division will solicit public comment on this draft permit by publishing a notice in newspapers having circulation in the general Beaufort County area,per EPA requirements. Please provide your comments,if any,to me no later than 30 days after receiving this draft permit. Following the 30-day public comment period, the Division will review all pertinent comments and take appropriate action prior to issuing a final permit. If you have questions concerning the draft, please contact me at 919-707-3619, or via e-mail [Brianna.Young@ncdenr.gov].

(4) DISCHARGE ALTERNATIVES EVALUATION [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 from the plant operator should be acquired. 2. Obtain a Non-discharge permit: Eliminate the surface water discharge by obtaining a non-discharge permit for spray irrigation, infiltration, or subsurface disposal (on-site drainfield, infiltration gallery, injection wells). 3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent to consistently pass the WET test. If this is not technically 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 the discharge or toxicity problem is eliminated. 5. Use Alternative Water Treatment Method: 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 waterbody/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. Page 6 of 10 Permit NC0084808 A. (2) ACUTE TOXICITY PASS/FAIL 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 address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic 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 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 5 of 10 Permit NC0084808 7. Combination of Alternatives: Employ any combination of the alternatives listed above that would result in eliminating or decreasing 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: http://portal.ncdenr.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 along with the submission of their next permit renewal application (due 6 months prior to permit expiration on November 30, 2024) to: NC DENR/Division of Water Resources/Water Quality Permitting NPDES, Wastewater Branch 1617 Mail Service Center, Raleigh, NC 27699-1617 A. (5) NUTRIENT REDUCTION REQUIREMENT Dischargers to the Tar-Pamlico River are subject to the requirements, terms, and conditions of the Tar- Pamlico Nutrient Sensitive Waters (NSW) Implementation Strategy: Phase III adopted April 14, 2005. Non- members of the Tar-Pamlico Association will maintain or receive permit effluent limits for Total Nitrogen and for Total Phosphorus concentrations as defined in the Strategy. Any revisions to the Strategy during the life of this permit are applicable. If requirements other than those listed in this permit are adopted as part of a revision to the Strategy, the Division reserves the right to reopen this permit and include those requirements. If requirements other than those listed in this permit are adopted to prevent localized adverse impacts to water quality, the Division reserves the right to reopen this permit and include those requirements. A. (6) ELECTRONIC REPORTING OF MONITORING REPORTS [NCGS 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.

(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). 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)]. Page 8 of 10 Permit NC0084808 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: https://www.federalregister.gov/documents/2015/10/22/2015-24954/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 electronic reporting waiver from the Division. To obtain an electronic reporting waiver, apermittee must first submit an electronic reporting waiver request to the � g � g q 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 duration 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 on eDMR and the application for a temporary electronic reporting waiver are found on the following web page: http://deq.nc.gov/about/divisions/water-resources/edmr 4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.)
