VAN DER VAART Secretary S. JAY ZIMMERMAN Director RECEIVEDINCDENRIDWR AUG 2 9 2016 WQROS MOORESVILLE REGIONAL OFFICE The U.S. Environmental Protection Agency (EPA) recently published the National Pollutant Discharge Elimination System (NPDES) Electronic Reporting Rule. The rule requires NPDES regulated facilities to report information electronically, instead of filing written paper reports. The rule does not change what information is required from facilities. It only changes the method by which information is provided (i.e., electronic rather than paper -based). EPA is phasing in the requirements of the rule over a 5-year period. The two phases of the rule, and their key milestones, are: • Phase 1—Starting on December 21, 2016, regulated entities that are required to submit Discharge Monitoring Reports (DMRs) will begin submitting these reports electronically. If you are currently reporting your DMR data electronically using eDMR, then you simply need to continue reporting in the same way as you are now. The key change is that, starting on December 21, 2016, electronic reporting of DMRs will be required, instead of voluntary. • Phase 2—Starting on December 21, 2020, regulated entities that are required to submit certain other NPDES reports will begin submitting these reports electronically. Reports covered in the second phase include Notices of Intent to discharge in compliance with an NPDES general permit, Sewer Overflow/Bypass Event Reports, and a number of other NPDES program reports. Incorporating Electronic Reporting Requirements into NPDES Permits The NPDES Electronic Reporting Rule requires authorized NPDES programs to incorporate electronic reporting requirements into NPDES permits beginning December 21, 2015. Under the new rule, the electronic reporting process supersedes the paper reporting process. According to our files, your NPDES permit became effective after November 2013, and should contain the requirement to electronically report your Discharge Monitoring Reports using NC DWR's eDMR system. In addition to requiring permittees to report information electronically, the rule also requires permittees to identify the initial recipient for the NPDES electronic reporting data [see 40 CFR 122.41(1)(9)]. Initial State of North Carolina I Environmental Quality I Water Resources 1617 Mail Service Center I Raleigh, North Carolina 27699-1617 919 807 6300 recipient of electronic NPDES information from NPDES-regulated facilities (initial recipient) 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)]. Permittees are required to electronically submit the required NPDES information to the appropriate initial recipient, as determined by EPA. By July 18, 2016, EPA must identify and publish on its web site and in the Federal Register a listing of initial recipients by state and by NPDES data group. Once available, you can use EPA's web site to find out or determine the initial recipient of your electronic submission. NC DWR has submitted a request to EPA to be the initial recipient for the following NPDES data groups: 1. Discharge Monitoring Reports; 2. General Permit Reports [Notices of Intent to discharge (NOls); Notices of Termination (NOTs)]; 3. Pretreatment Program Reports; and 4. Sewer Overflow/Bypass Event Reports EPA's web site will also link to the appropriate electronic reporting tool for each type of electronic submission for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. For more information on EPA's NPDES Electronic Reporting Rule, visit http://www2.epa.gov/compliance/final-national-pollutant-discharge-elimination-system-npdes- electronic-reporting-rule. For more information on electronic reporting to NC DWR, visit http://deg.nc.gov/about/divisions/water-resources/edmr/npdes-electronic-reporting or contact Vanessa Manuel at 919-807-6392 or via email at Vanessa.Manuel@ncdenr.gov.

Parker Regional Supervisor — Surface Water Protection NC DENR — Division of Water Quality Mooresville Regional Office 610 East Center Avenue, Suite 301 Mooresville, NC 28115 Re. NOV-2013-LV-0253 Dear Mr. Parker, APGI Yadkin Division Highway 740 PO Box 576 Badin, NC 28009 This letter is in response to the above -referenced NOV and the telephone conversation you had with Henk van der Meyden on April 22, 2013. Alcoa Power Generating, Inc. (APGI) is providing additional information to support our original claim that the pH sample collected on January 25, 2013 was not representative of the discharge from Outfall 002; that the reported pH value resulted from a blockage and stagnant water in the sampling line; and, that no discharge of actual low pH water occurred. We had previously indicated in our February 15, 2013 correspondence to the Mooresville Regional Office that this is what likely occurred, and, with additional sampling, have in our view since confirmed it. The pH reading in question was the only measurement taken in January and at the time of the DMR preparation, there was insufficient information to conclusively refute the result. Therefore, the result was reported and included in the DMR for January. As part of the follow- up investigation into the incident, and to ensure that the annual sampling requirement for Outfall 002 was satisfied, weekly pH readings were obtained in February and March. These results have been reported on DMRs submitted to the DWQ and clearly indicate that the pH values of the subsequent sampling from Outfall 002 are in compliance with the permit limits. Supporting pages from the two DMR reports are attached to this letter. Outfall 002 merely conveys Yadkin River water that is used as cooling water for the generator. There are no additives or processes that can affect the pH of this water before it is discharged. The design of the Narrows Powerhouse makes it physically impossible to safely collect a sample directly from the Outfall 002 discharge. Therefore, the pH measurement in question was of water, not from the actual discharge at Outfall 002, but from a closed end sample line. Prior to collecting the sample, the sample line was not purged, and therefore, the sample that was collected was of stagnant water that had built up in the sample line. For the subsequent pH sampling, the sample line was purged. This ensured that the sample collected represented what was actually being discharged. Again, all of the pH results from this subsequent sampling were compliant with the pH limits in the permit. This confirmed for us that the sample collected on January 25, 2013 was not representative of what was actually discharged at Outfall 002, and N therefore, no violation had actually occurred. Accordingly, we respectfully request that the above -referenced NOV be rescinded. We appreciate your consideration of this matter. If you have any questions or comments regarding this matter, please contact me at (704) 422-5774 or Henk van der Meyden at (843) 572-5361. Sincerely, T4 I " Mark vJ.s 11 attachments CC.

On 2013 January 25, a pH of 5.1 was measured in the discharge of Outfall 002 from the Narrows Powerhouse. This matter was discovered during the preparation of the DMR. Upon discovery this was immediately reported via telephone by Randall Kiser to Wes Bell in the NCDENR Mooresville Regional Office on February 13. At this time, and after interviewing the individual collecting the sample, we believe that the January measurement was not representative of the effluent being discharged, The Outfall 002 discharge is once -through cooling water and similar in nature and volume (>150,000 gpd) to the discharges of Outfalls 005 and 007. pH measurements taken at approximately the same time on the same day from these Outfalls showed values of 7.1 and 7.3, respectively. An additional pH measurement was taken on February 13, 2013 with a value of 7.32. The person collecting the measurement reported that the sampling line had very little flow and needed to be cleaned out before the sample could be collected. Stagnant water in the sampling line may have impacted the January measurement. APGI is working diligently to confirm the cause and solve the problem. We will be collecting additional pH measurements from this discharge over the next several weeks to confirm that this was indeed a non -representative sample. These results will be reported on future DMRs. In addition, standard procedures on collecting and reporting 56 Pr Alcoa Inc. APGI - Yadkin Highway 740 PO Box 576 Badin, NC 28009 of effluent measurements will be reviewed with the affected personnel, including the importance of immediate reporting.

The NPDES permit for the Narrows Powerhouse requires annual monitoring of temperature & pH for the non -contact cooling water discharges from the generators. The ORC planned on performing the monitoring during the fourth quarter of 2007, however, during the fourth quarter Narrows Unit #2 was taken down for an extended maintenance outage and the ORC was unable to perform the required monitoring for Outfall 006 during 2007. The remaining three units which are exactly like unit #2 were monitored as required and were determined to be in compliance with the permit. APGI will perform the required monitoring on unit #2 as soon as the unit is returned to service in the Spring of 2008. If you have any questions regarding this matter, please feel free to contact me at (704) 422 -5774.

The spill occurred about 9:30 a.m. on 5/15/06 while a contractor was utilizing a concrete saw to cut through the concrete decking above the flood gates at the Narrows Powerhouse. While making a cut, the contractor noticed oil dripping from the breather cap on the saw. In the process of moving the saw, it is estimated that approximatel 6 — 8 ounces of oil spilled onto the concrete deck. The contractor's employees took imme 1a e steps to contain and clean-up the oil that was spilled by applying oil absorbent and using rags to wipe it up. The defective equipment was removed from the job site and replaced with properly operating equipment. There was no release to any surface water, however, since the spill occurred within 100 feet of Badin Lake, Alcoa is reporting the spill in accordance with G.S.143-215.85.
