Not less than three months, nor more than six months, unless by written agreement of the parties, from the effective date of the renewed permit, and upon request of the permittee, DWR will perform an instream assessment of the receiving stream, Flat Creek, to assess both water quality parameters and macroinvertebrates populations, DWR will notify Permittee of the date of the instream assessment in sufficient time that Permittee can arrange for an independent third party to attend and share samples collected. If it is determined that the permitted discharge from the facility is not causing stream degradation resulting in water quality standards violations, including narrative standards, which determination shall not be unreasonably withheld, then DWR will grant Permittee discharge of up to 0.05 MGD provided the facility is being operated in a manner such that it is compliant with its Permit. The Permittee may voluntarily hire an independent third party to do an instream assessment using DWR approved instream assessment methodologies at any time. Permittee will provide DWR sufficient notice of sampling so that DWR may have their personnel attend and share samples collected. DWR will consider such data in conjunction with its own instream data, when making its determination of whether water quality standards are being contravened as a result of the NPDES discharge. b. The Permittee may make a written request that a stream assessment be performed by DWR prior to the date established above as long as the facility is compliant with its Permit NC0067342, but no sooner than three months from the effective date of permit. The Permittee may hire a third party to perform an instream assessment using DWR approved instream assessment methodologies; DWR will consider the data from the assessment when making its compliance determinations. Continued noncompliance at the facility may prevent DWR from approving discharge greater than 0.032 MGD. c. If DWR denies the expanded flow above 0.032 MGD, then the Permittee. may request another DWR assessment be done annually (from the date of the last instream assessment) thereafter. A. (5) SPECIAL CONDITIONS 1. The flow monitoring device cannot be changed without prior approval from the Division. Flow must be logged using an electronic data logger to be installed within 6 months after the permit effective date.

(a)I 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.

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 Page 6 of 9 Permit NCO067342 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 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.
