The compound 1, 2 Dichloroethene was included in error and is hereby replaced by Cis-1,2 Dichloroethene [code 77093]. Please note that we have updated the parameter codes in permit Section A. (L), in the attached changes -pages. Please insert these change -pages in your currently active permit and discard the old pages. The Division regrets any inconvenience this may have caused your organization. If you have questions, please contact Joe R. Corporon, L.G. at [ioe.corporon cr ncdenr. ,ovl or call his direct line (919-807-6394). in rely, S.

(L) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS [NCAC 02B.0400 et seq., 02B.0500 et seq.] During the period beginning on the effective date and lasting until expiration, the Permittee is authorized to discharge treated wastewater from Outfall 001. Such discharges shall be limited, monitored and reported 1 by the Permittee as specified below: EFFLUENT CHARACTERISTIC [PARAMETERS CODES] MONITORING REQUIREMENTS Monthly Average Daily Maximum Measurement Frequency Sample Type Sample Location Flow (MGD) 50050 0.0432 Continuous Recording Effluent pH 00400 Not < 6.0 or > 9.0 s. u.

Beginning no later than 270 days from the effective date of this permit, the Permittee shall begin reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application [See Section A. (3.)]. 2. After a minimum of 12 sample events, the Permittee may petition the Division to review analytical data and revise the monitoring frequency, as data may warrant. 3. Chronic Toxicity - Whole effluent Toxicity (WET) testing using Ceriodaphnia dubia, P/F (a 90 %; during the months of January, April, July, and October [See section A. (2.)]. Conditions: • Each effluent sample event shall accurately represent the physical and chemical character of the discharge. Page 3 of 6 Permit NCO089508 A. (2.) CHROMIC TOXICITY PASS/FAIL - MONITOR QUARTERLY [G.S. 143-215.1(b)] The Permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the `North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions. The effluent concentration defined as "treatment two" in the procedure document is 90 %. The testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. 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 flow, and shall be performed at the NPDES permitted effluent's final discharge point 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 TGP3B. Additionally, DWR Form AT-1 (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 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.
