Asheville Steam Electric Plant NPDES Permit No. NC0000396 Buncombe County Renewal Application Dear Mr. Belnick: The current NPDES permit for the Asheville Steam Electric Plant expires on December 31, 2010. Progress Energy hereby requests that the NPDES permit for the facility be reissued. Enclosed are EPA Application Form 1 — General Information, EPA Application Form 2C — Wastewater Discharge Information and EPA Application Form 2F — Stormwater Discharges Associated with Industrial Activity, all in triplicate. As we have previously discussed with DWQ staff, in order to facilitate enhancements to the existing dam of our 1964 ash pond, Progress Energy proposes to relocate outfall 001 to a point approximately 3000 feet downstream of its current location. This relocation will be necessary to allow for additional stabilization work to be undertaken on the existing 1964 ash pond dam. The proposed relocation is to a point where access under Interstate 26 already exists. Coordinates for the proposed discharge point are North 35.47367 and West - 82.504. Enclosed with this renewal application is information pertaining to the 7Q10 and IQ 10 flows provided to us by staff of the USGS for this location. With reissuance of the NPDES permit, Progress Energy requests the following language regarding usage of biocides and the completion of the Biocide Form 101 be added to the permit: The permittee shall not use any biocides except those approved in conjunction with the permit application. The permittee shall notify the Director in writing not later than ninety (90) days prior to instituting use of any additional biocide used in cooling systems which may be toxic to aquatic life other than those previously reported to the Division of Water Quality. Such notification shall include completion of Biocide/Chemical Treatment Worksheet —Form 101. Division of Water Quality approval is not necessary for the introduction of new biocides into outfalls that are tested for whole effluent toxicity. Completion of the Biocide Worksheet is thus, not necessary for those outfalls with toxicity testing requirement. In addition, Progress Energy also requests the following reductions in monitoring requirements based on analysis of sampling results during the term of the current permit: Progress Energy Carolinas, Inc. Asheville Steam Plant 200 CPU Drive 1 Arden, NC 28704 Outfall 005 Remove sampling requirements for Beryllium, Cadmium, Chromium, Copper, Lead, Manganese, Nickel, Silver, Thallium, Zinc and Fluoride Outfall 001 Remove monitoring requirements for Beryllium, Cadmium, Chromium, Coopper,,Lead, Manganese, Silver, Thallium, Zinc, Fluoride, Total Nitrogen and To a1 pho_� Reduce required monitoring for Mercury to twice per month -ou Condition A.(7) of the,current NPDES permit for the Asheville Steam Electric Plant requires that Progress Energy request a continuation of its 316(a) variance beyond the term of the present,permit Enclosed is an EPA guidance letter dated August 11, 1988 outlining the general procedure to be followed in requesting the continuance of a316(a) variance The following, is Progress Energy's response to the pertinentYfactors contained in the EPA general procedure for the reissuance of the 316(a) variance. 1 The permittee must request the variance be continued Response Progress Energy hereby requests continuation of the 316(a) variance reflected in its present NPDES permitfor the Asheville Steam Electric Plant 2. Plant operating conditions and load factors are unchanged and are expected to remain so for the term of the reissued permit Response The plant operating conditions and load factors are unchanged and are expected to remain so for the term of the reissued permit 3 There are no changes to the permittee's knowledge to the plant discharges or other discharges in the plant area which could interact with thermal discharges Response During periods of drought, as makeup water is pumped from the French Broad River to Lake Julian to sustain, operating cooling water levels, Progress Energy staff suspect there may be some influence m Lake Julian from our upstream discharge point in the French Broad River This permit application includes a proposal to relocate the discharge point from the facility's ash pond (outfall 001) to facilitate enhancements to the facility's 1964 ash pond dam. This outfall relocation should also eliminate any potential influence in Lake Julian from our discharge in the French Broad River 4. There are no changes to the permittee's knowledge to the biotic community of the receiving water body which could impact the previous 316(a) determinations Response- As demonstrated by Progress Energy's environmental monitoring, since issuance of the current NPDES permit there have been no changes to the biotic community of Lake Julian which would impact the previous 316(a) determinations If you have•any questions regarding the enclosed information, please contact Shannon Langley at (919) 54'6 -2439 I cent, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qual f ed personnel properly gather and evaluate the information submitted Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete I am aware that there pare significant penalties for submitting false information, including the, possibility of fines and imprisonment for knowing violations Sincerely, - M, ��� Garry A Whisnant Asheville P1ant,Manager Enclosures CC.

The following, is provided as 'a, follow�up to information provided at the February 1988, EPA/State meeting in Aestin, Florida. J A thermal variance granted under 5316(a) terminates on, expiration of the NPDES permit of which it is a, part (Attachment A). Procedures for a reissuance are virtually unchanged from an initial determination. The amount of data necessary to support the variance at the time of reissuance will probably be minimal. Bkxmver, if conditions have changed materially, a significant quantity of informa- tion may be needed. NEE: Tb the extent that permittees are unaware of these, regUirements, they should be notified, of they expeditiously so that they can be prepared. The general procedure is as follows: I. The permittee must request that the variance be continued, preferably at the time of permit application. At that time, he should provide a basis for that continuance. The basis couldbe as simple ash (•a) plant operating conditions -and load factors are unchanged and are expected to remain so for the term of the reissued permit, (,b) there are no changes (to his knowledge) to plant discharges or other discharges in the plant site area which could interact with the thermal discharges, and (c) there are no. changes (-to his knowledge) to -the biotic community of the receiving water body which would impact the previous 316 determinations. 2. If the permitting authority agrees with the, basis, appropriate permit oondi- t -ions would be developed; otherwise, additional data would be requested as needed. Request for additional data must be made within 60 days of receipt of the application ,(Answier to Question 7, Attachment A) . Additional studies can be made a permit requirement if needed '(Answer to Question 7.1. Page 2 August 11, 1988 0 3. The Fact Sheet/Utionale should contain a summ' ary of 316 variance activities from the - previous permits (dates, deteLminations, limitations, etc.) and indication of the proposed basis for continuing the 316 variance. an language is included in, Attachment B.

Division of Water Quality, NFDES Unit 1617 Mail Service Center Raleigh, North Carolina 27699 -1617 Dear Ms. Wilson: In response to your request for low -flow data, the U.S. Geological Survey (USGS) does not have site - specific, low -flow discharge data for French Broad River at NC'280 near Skyland, NC (station id 03447840, drainage area 660 m12): The low -flow characteristics that are pro- vided on the attached sheet have been computed by correlating the runoff characteristics of a nearby continuous - record gaging station upstream of the request site., Please note that the.flow, estimates do not- specifically account.for the presence of any diversions. or regulation, present or future, which may occur upstream of the request site. Because afsimilar request for the 1Q10 low -flow discharge was received about.the3 same time from Progress Energy, this, low» flow statistic is included on the attached sheet. Low -flow characteristics were analyzed using streamflow records from a continuous - record gaging station on the'French Broad River near Fletcher, operated since July 2001 and located upstream at Secondary'Road 1419 (station id 03447840, drainage area 640 m12). Because of the short period of record at the Pletcher gage, low -flow analyses at this gage were completed by correlation analyses using two' other gaging stations having Wong periods, oftecord (station id's 03443000 and 03451500). 'Shen, using the difference in drainage areas between the request site,and,the K, etcher gage, low -flow characteristics at the- request location were deter- mined using the low -flow yields' (expressed,as flow per square mile drainage, area) at the Pletcher gage. The estimated 7Q10 discharge is 306 W/s and is lower than the estimate pro- vided to `you in an e-mail dated January 14, 2004. Analyses of `low -flow characteristics at all three gaging stations indicates 'a decreasing, trend in low -flow yields between the gages -at Blantyre and Asheville. Between these two locations, thexiver is affected by some diversions occurring4n tributaries along with regulation by small upstream reservoirs and a power plant located about 8 miles upstream of,Blantym The anal- yses indicate that most of the decrease in low -flow yields occurs between the Blantyre and Fletcher gages. The table shown on the accompanying page summarizes the low-flow characteristics at the gaging stations used in the analyses. As previously discussed in January, the French,Broad River downstream from3lantyft is affected by some'regulation and diversions. The low -flow discharge values are baked on stream,flow records available through September 2003, and the associated low-flow yields for each value is listed to provide insight in the changing low -flow yields between the gages, (919) 571 -M - FAX (919) 571-4041 Ma r, 16. 2010 1; 4'9 PM No. 2 6U N. 4 Ms. Susan A.

Asheville Steam Electric Plant National Pollutant Discharge Elimination System Permit Number NC0000396 Attachment 9 Proposed conceptual relocation route of outfall 001 Proposed relocation of outfal 001 In order to facilitate enhancements to the 1964 ash ,pond -dam,, it will be necessary to relocate'the existing settling basin and discharge outfall 001. The Asheville Steam Electric Plant is located in close proximity to the French Broad River but has limited access to the river,because of Interstate 26. In order to relocate, outfall 001, it will be necessary to go north approximately 3000 feet to a point where existing access under the Interstate is located. This proposed discharge location is on property owned by Progress Energy The entire span of property between the existing outfall and the proposed outfall is also owned by Progress Energy. In addition to the current °flows from the 1982 ash pond, a "new" flow will be added to the relocated outfall. This flow will consists of stormwater and ground water, seepage that currently'flows into the 1964 ash pond. H tsi cas flow has been allowed to evaporate and /or infiltrate. The enhancements to the 1964 pond require that this water level be managed and maintained below a certain elevation. 'Therefore, it may °be necessary to periodically pump water from the 1964 ash pond to the combined, relocated settling basin and outfall 001 A sample of the water from the 1964 ash pond was taken as part of the preparation of this application Results from that sampling analysis are attached. a) P L) U 13) _0 _0 0 a) 0- 0 (3) bio c cr- 06 L N E _0 0 u 0 : fU 4- ro bjO L- 4- 4� co a) C: (1) CLO cl a) 4- Ln C) a) P L) U 13) _0 .r_ L) 0 a) 0- 0 (3) (A M cr- 06 L N E _0 u 0 : fU co a) C: C) x 0 bb uo -0 U L- m to W -C u S -2 -C u Z 0 z < 0 w T Ln rl N ro d Ln -1, +1 4 i (� IaceAnalytkal wwwpacelabxcwn April 23, 2010 Ms Crystal Diedrich Progress Energy 200 CP &L Drive Arden, NC 28704 RE Project DUCK POND 04/12 Pace Project No 9267173 Dear Ms Diedrich Pace Analytical Services, Inc 2225 Riverside'Dr Asheville, NC 28804 (828)254 -7176 Pace Analytical Services, Inc 9800'KinceyAve Suite 100 Huntersville, NC 28078 Enclosed are the analytical results for'sample(s) received by the laboratory on April 12, 2010 The results relate only to the samples included in this report Results reported herein conform to the most current NELAC standards, where applicable, unless otherwise, narrated in the body of the report Inorganic Wet Chemistry and Metals analyses were performed at our Pace Asheville laboratory and Organic testing was performed at�our Pace Huntersville laboratory unless otherwise footnoted All Microbiological analyses were performed at the laboratory where the samples were received If you have any questions concerning this report, please feel free to contact me Sincerely;
