WQCS00129 ) HELD BY ) THE TOWN OF MOUNT OLIVE ) Pursuant to provisions of North Carolina General Statute(G.S.) 143-215.2 and G.S. 143-215.67, this Special Order by Consent is entered into by the Town of Mount Olive, hereinafter referred to as the Town, and the North Carolina Environmental Management Commission, an agency of the State of North Carolina created by G.S. 143B-282, and hereinafter referred to as the Commission: 1. The Town and the Commission hereby stipulate the following: (a) The Town holds North Carolina NPDES Permit NC0020575 for operation of an existing two million gallon per day (mgd)wastewater treatment works and for making an outlet therefrom for the discharge of one mgd treated wastewater to the Northeast Cape Fear River, Class C;Sw waters of this State in the Cape Fear River Basin. The Town also holds Non-Discharge Permit WQ0029169 for operation of a 560,893 gallons per day reclaimed water generation, distribution, and utilization system but is unable to operate the system at its design capacity. The failure to manage this system has contributed to noncompliance of the wastewater treatment plant,which discharges the excess flow to the Cape Fear River in violation of its monthly effluent flow limits as set forth in NC0020575. Additionally,the Town holds Permit Number WQCS00129 for operation and maintenance of approximately 32 miles of gravity sewer, 5 miles of force main, and 15 duplex pump stations to make a complete and functional collection system. The Town has had persistent issues with inflow and infiltration within this system, which contributes to flow limit violations at the WWTP. The Town has also received notices of violation due to sanitary sewer overflows(SSOs) at the influent pump station and manhole at the WWTP. The Town continues to be in noncompliance with permit conditions and limits for flow of their NPDES Permit NC0025075. The Town seeks to discharge an average of 2.4 MGD to the Northeast Cape Fear River while repairs and enhancements to the spray irrigation facility permitted under WQ0029169 are completed. During construction of the improved system, the non-discharge system will be unable to receive any flow, necessitating additional discharge into surface waters. The persistent inflow and infiltration issues within the collection system are further contributing to flows beyond Town of Mount Olive—Mount Olive WWTP EMC SOC WQ S20-002.1 Page 2 of 8 the current capacity of the WWTP. This SOC relaxes the flow limits set forth in the NPDES permit to 2.4 mgd while maintaining the permitted nutrient loads. There will be no net increase of pollutants to the River with this increased flow. Compliance will require preparation of plans and specifications for construction and operation of additional treatment works and influent pump station improvements. (b) Noncompliance with fmal effluent limitations constitutes causing and contributing to pollution of the waters of this State named above, and the Town is within the jurisdiction of the Commission as set forth in G.S. Chapter 143, Article 21. (c) The Town has secured a grant or has otherwise secured financing for planning, design, and construction/repairs of the following: i. Improvements to the influent pump station, including construction of a new 18-inch force main. ii. Removal of influent bypass pump station from service. iii. Modification of the WWTP headworks to receive increased flow from the improved influent pump station. iv. Rehabilitation of two of the four WWTP tertiary filters to increase filter efficiency,return the filters to their design flowrates,and eliminate frequency of bypass. v. Installation of a new Parshall flume to increase the accuracy of effluent flow monitoring. vi. Upgrade of the existing irrigation pump station,and irrigation system controls,to be compatible with the proposed spray irrigation system.A new transfer pump station wetwell will be installed. vii. The existing sycamore tree crop and drip irrigation system will be replaced with a grass crop and spray irrigation system. (d) Since this Special Order is byConsent, neitherwill file a petition for a contested Pparty case or for judicial review concerning its terms. 2. The Town, desiring to comply with the Permits identified in paragraph 1(a)above, hereby agrees to do the following: (a) Undertake the following activities in accordance with the indicated time schedule: 1) On or before September 30,2020, submit complete plans and specifications for the WWTP repairs along with the appropriate permit applications and fee.

NCDEQ will not enforce pass/fail limits for tests that take place for the quarters where oxidation ditches and tertiary filters are online for service.In all other quarters,the Town must comply with toxicity requirements. 7. The permittee shall perform three Effluent Pollutant Scans during the term of this permit[see A.(4.)]. 8. Effluent Total Hardness sampling should be performed in conjunction with sampling for hardness dependent metals(cadmium,copper,lead,nickel,silver,and zinc). 9. See A.(3.)for instream monitoring requirements. There shall be no discharge of floating solids or visible foam in other than trace amounts. • A. (2.) CHRONIC TOXICITY P/F PERMIT LIMIT(QUARTERLY) [15A NCAC 02B.0200] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 90% at 2.4 MGD flow regime. The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"(Revised-December 2010)or subsequent versions.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. 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-December 2010) 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, DWR Form AT-3 (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 Or, results can be sent to the email: ATForms.ATBAa,ncdenr.gov. 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, 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 Water Sciences Section 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. Assessment of toxicity compliance is based on the toxicity testing quarter,which is the three-month time interval that begins on the first day of the month in which toxicity testing is required by this permit and continues until the final day of the third month. Should any test data from this monitoring requirement 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, 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. A. (3.)INSTREAM MONITORING REQUIREMENTS [15A NCAC 02B .0500 et seq.] Upstream samples shall be collected at least 50 feetfrom h p pthe outfall.

The Permittee must at least report completion of the test in the eDMR system by entering"1"or"Y"for parameter code NC01 -Annual Pollutant Scan. If utilizing the • DWR Form submit to the following address: NC DEQ/DWR/NPDES Files, 1617 Mail Service Center, Raleigh, North Carolina 27699- 1617. Or the form may be uploaded at: https://edocs.deq.nc.gov/Forms/NPDES_WW-EDMR- Supplemental-Form Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5). The US EPA requires four(4)toxicity tests for a test organism other than the test species currently required in this permit. The multiple species tests should be conducted either quarterly for a 12-month period prior to submittal of the permit renewal application, or four tests performed at least annually in the four-and one-half-year period prior to the application. These tests shall be performed for acute or chronic toxicity, whichever is specified in this permit. The multiple species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following address: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional toxicity tests and reporting requirements. Results should also be summarized in Part E (Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal application to the NPDES Permitting Unit. A. (5.) 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 II of this permit(Standard Conditions for NPDES Permits): • Section 13.(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) interne 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)]. 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-el im ination-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, 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 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/di vi sion s/water-resources/edmr 4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.)(d)1 All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B. (11.)(a)or by a duly authorized representative of that person as described in Part II,Section B.(11.)(b). A person,and not a position,must be delegated signatory authority for eDMR reporting purposes. For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and login credentials to access the eDMR system. For more information on North Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following web page: http://deq.nc.gov/about/divisions/water-resources/edmr Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE ACCEPTED: "I certifr, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility offines and imprisonment for knowing violations." 5. Records Retention [Suonlements Section D. (6.)1 The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions. These records or copies shall be maintained for a period of at least 3 years from the date of the report. This period may be extended by request of the Director at any time [40 CFR 122.41].
