Such discharges shall be limited and monitored' by the Permittee as specified below: EFFLUENT CHARACTERISTICS Parameter Codes LIMITS MONITORING REQUIREMENTS Monthly Average Daily Maximum Measurement Fre uenc Sample Type Sample Location Flow 2 50050 ,' Daily Estimate Effluent Total Suspended Solids C0530 30.0 mg/L 45.0'mg/L 2/Month Grab Effluent pH 00400 Not less than 6.0 S U. nor greater than 9.0 S.0 2/Month Grab Effluent Total Residual Chlorine 3 50060 17 pg/L 2/Month Grab Effluent Turbidity, NTU 00070 2/Month Grab Effluent Total Fluoride, pg/L 00951 Quarterly Grab Effluent Total Manganese, pg/L 01055 ' Quarterly Grab Effluent Hardness — Total as 00900 CaCO3 or Ca + M 5 Quarterly Grab Effluent Hardness — Total as 00900 CaCO3 or Ca + M 6 Quarterly Grab Upstream Total Nitrogen 4 (TN), mg/L C0600 Semi-annual Grab Effluent Total Phosphorus (TP), mg/L C0665 , -Semi-annual Grab Effluent Footnotes • f 1. The permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR application system [see A. (2)]. 2. Flow estimate shall be based on daily discharge activities to outfall. Duration and flowrate of discharge should be noted in log book and supported flows reported on DMR. 3. The Division shall consider,all effluent TRC values reported below 50 µg/L to be in compliance with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 µg/L. 4 TN = TKN + NO3-N + NO2-N; where TN is Total Nitrogen, TKN is Total Kjeldahl Nitrogen, and NO3-N + NO2-N are Nitrate and Nitrite Nitrogen respectively. 5. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals (cadmium, copper, lead, nickel, silver, and zinc). 6. The Permittee shall sample instream hardness, upstream of the facility's discharge The sample shall be representative of the hardness in the receiving stream. If the Permittee is a member of the Monitoring Coalition Program, sampling for instream hardness may be waived as long as the Monitoring coalition agrees to sample hardness at the nearest upstream location, at a minimum frequency of quarterly, and the Permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being monitored by the Coalition is representative of the receiving stream for this discharge. The Permittee is responsible for submitting instream hardness test results with its permit renewal application package. If Coalition membership is cancelled or the Coalition terminates instream hardness sampling at the approved station, the Permittee will immediately notify the Division and resume sampling for instream hardness, upstream of its discharge. Page 3 of 6 Permit NCO086918 All samples collected should be from a representative discharge event. There shall be no discharge of floating solids or visible foam in other trace amounts. A. (2) 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. NOTE: This special condition supplements or supersedes the following sections within Part II 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. Page 4 of 6 Permit NC0086918 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-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, 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.ne.gov/about/divisions/water-resources/edmr 4. Sisnatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.)

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.
