We issue this permit pursuant to the requirements of North Carolina General Statute 143- 215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994,or as subsequently amended. The Division acknowledges your purchase of the subject site(documents received December 21, 2006), and your authorization of Tracy B. Robinson, site Production Manager, to provide information and sign reports, as required under this permit. Concerning Total Residual Chlorine(TRC). In compliance with the statewide standard for chlorine, the Division must deny your request to remove the TRC limit(17 ug/L) and Monthly monitoring from the permit. However, footnotes have been added to the effluent-monitoring table to explain that monitoring and limits apply only if chlorine is used by the'facility[See permit Section A. (1.)]. Receiving-Stream Flow Conditions. Please be reminded that subject site discharges under"zero-flow" stream conditions(dry ditch), i.e., your discharge constitutes effectively 100% of local surface waters. This means that your effluent enters the surface environment with little or no benefit from dilution. Changes to your Previous Permit—Oil& Grease,Lead, and Naphthalene. As part of renewal, the Division conducted a Reasonable Potential Analyses (RPA) on your analytical data for lead, as required by the NPDES Program. Based on this analysis,the Division finds no reasonable potential to exceed the instream water-quality Standard for lead. Therefore, monitoring for Total Lead has been removed from your permit. Similarly, and for the same reason, Oil & Grease monitoring has been discontinued. However,to better evaluate the potential loss to the environment of#2 diesel (your preferred back-up fuel source at this facility),the Division has added the parameter Naphthalene [See permit Section A. (1.)]. There are no other changes to your previous permit. ern NCDENR North Carolina Division of Water Quality 1617 Mail Service Center Raleigh,NC 27699-1617 (919)733-7015 Customer Service 1 800 623-7748 Duke Energy Carolinas,LLC Rockingham County Combustion Turbine Facility Issuance of NPDES Permit NC0086665 Page 2 If any parts,measurement frequencies, or sampling requirements contained in this permit are unacceptable,you have the right to an adjudicatory hearing upon written request within thirty(30)days after receiving this letter.

Permit Development • Receiving Stream. Historical.data indicates this discharge occurs under zero-flow Conditions. • Historical NPDES Permitting. This permit was originally issued in November 1999 and reissued in January 2001.The Division received a renewal application from the Previous owner(Dynegy Inc.) on September 8,2006 and Duke Energy(upon purchase of the property)did not alter the application. • Effluent Guidelines. EPA Effluent Guidelines(40 CFR 423)apply only to steam turbine facilities, therefore these guidelines do not apply to this facility(peak demand via combustion gas turbines). • The previous permit regulated parameters typical to cooling water discharges(e.g.,turbidity and temperature)and parameters associated with bulk oil storage terminals(Acute toxicity,TSS,Oil& Grease,EPA Method 624/625).This renewal maintains the same limits and monitoring,with the exception of minor changes see(Table 2). Permit Compliance • Effluent Toxicity. Facility passed 5 of 5 annual acute toxicity tests(24-hour, fathead minnow)from 2003 to 2007. • Effluent Parameter Monitoring. O&G max predicted= 19.9 mg/L No RP assuming allowable at 30 mg/L(BPJ).Lead not detected in—30 samples(Jan04 to Jul07).Flow reported—monthly;range 0.004 to 0.092 MGD(Jan04 to Jul07). • Monitoring for BTEX. BIMS recorded four frequency violations(not tested)for BTEX (benzene, toluene,Ethylbenzene,and Xylene)—required semi-annual testing not reported in Dec 2005,Jun 2006,Dec 2006,Jun 2007.However,with the change in ownership from Dynegy to Duke Power (December 2006),BTEX was sampled and reported in January 2007.DMR results show"not detected."Therefore,DWQ will take no assessment action [previous owner's violations(BPJ)].

Rockingham's original application was previous submitted on July 5, 2006 and returned by your NPDES Unit on July 11, 2006. With receipt of your August 28, 2006 letter, Rockingham is now resubmitting the application. The application consists of one original and two copies of the Application Short Form C and supporting information including site location map, site layout drawings, and water/wastewater flow diagram, and recent monitored data. The effluent data provided in Item 15 of the Short Form C are based on the April 2005 through May 2006 reports. We understand that there is no application fee for the filing of this renewal application. With this application, Rockingham Power, LLC also requests the following changes to the permit: 1) Removal of TRC sampling and limit. Rockingham Power, LLC does not use or add chlorine at the plant. Any residual chlorine would originate from the water supply. Since August 19, 2002 no excursions of the TRC limit have occurred at the discharge location (Outfall 001). Based on the distance from the discharge location to the receiving stream (approximately 1,500 feet), the discharge would have no impact. The discharge flows overland through a dry drainage way into a small detention pond which upon overflow runs into the un-named tributary to Jacob's Creek (the receiving stream). Page 2 Rockingham NPDES Renewal Application Additionally, on June 8, 2006, three samples were collected at the detention pond and three were collected at the un-named tributary. Tests results on these samples did not detect TRC (lab reports enclosed). The removal of this limit has been discussed with Mr. David Russell of your office. He has visited the site and agreed that TRC should not be considered an issue or limit, and should not continue to be monitored at the Rockingham Power, LLC site. 2) Removal of the limit and monthly monitoring requirement for lead. For the last three years, Rockingham Power, LLC has collected data showing levels much less than the chronic in stream water quality standard of 25 pg/I.

The application consists of one original and two copies of the Application Short Form C and supporting information including site location map, site layout drawings, and water/ wastewater flow diagram, and recent monitored data. The effluent data provided in Item 15 of the Short Form C are based on the April 2005 through May 2006 reports. We understand that there is no application fee for the filing of this renewal application. With this application, Rockingham Power, LLC also requests the following changes to the permit: 1) Removal of TRC sampling and limit. Rockingham Power, LLC does not use or add chlorine at the plant. Any residual chlorine would originate from the water supply. Since August 19, 2002 no excursions of the TRC limit have occurred at the discharge location (Outfall 001). Based on the distance from the discharge Iodation to the receiving stream (approximately 1,500 feet), the discharge would have no impact. The discharge flows overland through a dry drainage way into a small detention pond which upon overflow runs into the un-named tributary to Jacob's Creek (the receiving stream). Additionally, on June 8, 2006, three samples were collected at the detention pond and three were collected at the un-named tributary. Tests results on these samples did not detect TRC (lab reports enclosed). Page 2 Rockingham NPDES Renewal Application The removal of this limit has been discussed with Mr. David Russell of your office. He has visited the site and agreed that TRC should not be considered an issue or limit, and should not continue to be monitored at the Rockingham Power, LLC site. 2) Removal of the limit and monthly monitoring requirement for lead. For the last three years, Rockingham Power, LLC has collected data showing levels much less than the chronic instream water quality standard of 25 pg/I. The necessity of this effluent limit in the permit was noted for possible removal in the prior permit renewal dated May 10, 2004. 3) Removal of the semi-annual monitoring for BTEX. Toluene has been well below the state water quality standard of 11 pg/I during the past sampling periods (0.0054 mg/L on 1/18/2005 and below quantification limits for previous more recently). The necessity of this effluent limit in the permit was noted for possible removal in the prior permit renewal dated May 10, 2004 If you should have any questions or require further information, please do not hesitate to contact me at 336-951-1772 or Ms. Barbara Irwin at 217-872-2363 of our environmental group.

Describe the treatment system List all installed waste treatment components with capacities, describe the processes that generate wastewaters. If the space provided is not sufficient attach a separate sheet of paper with the system description. Oil-water separator and coalescing filter with a capacity of 11,600 gallons receives contact stormwater (from around oil storage sources), service water system blowdowns, area washdown, and air conditioner condensate discharges associated with Combustion Turbine Units 1 through 5, and turbine inlet cooling water system blowdowns from Units 1 through 4. The oil-water separator discharges are primarily influenced by precipitation and plant operations. Design average and design maximum instantaneous discharge flowrates from the separator (and Outfall 001) will be 100 gpm and 200 gpm, respectively. Discharge durations will range from 10 to 30 minutes. The collected oil and solids at the separator are pumped out by a contractor (e.g., Noble Oil) and taken offsite for recycling or disposal. The need for cleaning is fairly infrequent with the most recent occurring in June 2003. 8. Is facility covered under federal effluent limitation guidelines?

The coordinates the permittee gave (see below e-mail) , appear to be the outfall and "land" almost directly on a UT Little Jacobs Creek in Subbasin 030202; just off NC 65. Charles Weaver wrote: Bryn, I 've attached the fact sheet from the most recent permit renewal. Tom Belnick noted that the receiving stream was a UT to Jacobs Creek in subbasin 30203 . However, BIMS does not locate any part of Jacobs Creek in 030203, placing it in 030202 . I picked stream segment 22-32- (0. 5) when updating BIMS as it was closest to the location given for the UT - it also had the correct stream classification. However, the actual outfall location is in 030203 . . . . Permitted flow is not limited - this is a power plant and flow limits are not required. Finally, the Permittee lists a lat/long of 36419 ' 52" / 79449 ' 40" in their renewal application. . .but they don' t say whether that' s for the facility or for the outfall. C HW Bryn H.
