Asheville Steam Electric Plant National Pollutant Discharge Elimination System Permit Number NC0000396 Attachment 3 Form 2C - Item II -B Flow, Sources of Pollution, and Treatment Technologies The Asheville Steam Electric Plant'is located in Arden, North Carolina south of Ashevi_Ile, North Carolina The Asheville Steam Electric Plant is a coal - fired, steam cycle electric generating plant with ,two generating, units Two Internal Combustion (IC)` Turbines are also located'on the plant site. The plant has a 320 -acre cooling lake (Lake Julian) on the east side of the French Broad River in Buncombe County, North Carolina Chemical constituents contained in the discharges from this plant will, in part be representative of the naturally occurring chemical quality of the intake water and will also have chemical constituents of such quality and quantity associated with similar discharges for fossil generating facilities of this size, type and in this geographical location. Either all or part of the elements listed on the Periodic Table, either singularly or in any combination, may from time to time be contained in' the discharge Outfall 001 - Discharge from Ash Pond to French Broad River The Plant's ash pond, which is located east of the French Broad River and south of the plant, discharges into,the French Broad' River. The, ash pond receives ash sluice water,, lowIvolume wastes, coal pile runoff, limestone pile runoff,' gypsum pile runoff„ air preheater cleaning water, fire protection system drainage, chemical metal, cleaning wastes (potentially), storm water and other waters from the Combustion Turbine Facility constructed on the Plant's site The proposed truck wash and weigh stations will also discharge to the Ash Pond The pond provides treatment by sedimentation and ,neutralization to the aboVe- referenced individual waste streams Water leaves the ash pond via a standpipe with skimmer and flows by pipe and lined ditch to a secondary basin, where it is discharged by overflow to a ditch that coveys it to the French Broad River. Detailed descriptions of the individual waste streams are below., Ash Sluice: Water Fly ash, and bottom ash from both units are hydraulically conveyed by an ash sluice pipeline to the ash pond The Amine Enhanced Fuel Lean Gas Reburn (AEFLGR) process which was installed on Unit 1 in the spring of 2000 will be replaced by a Selective Catalytic Reduction 1 Carolina Power & Light Company Asheville Steam Electric Plant National Pollutant Discharge Elimination System Permit'Number NC0000396 system (SCR) that will begin operation in 2008 A SCR will be installed on Unit 2 and will begin operation,zin 2006 Urea will continue'to be utilized to reduce NOx emissions and will, be used in high ozone months (approximately May through September) Beginning in 2009 both SCRs will be operated year round A byproduct of this process is ammonia which will be carried to the ash pond via ash sluice water The ash pond discharge flows into the secondary settling pond where it combines with the FGD treated wastewater prior to discharging to the French Broad River Coal, Pile Runoff Storm,water runoff from the coal pile,is collected in drainage ditches that surround the coal pile. The drainage ditches are routed to the ash pond for treatment. During maintenance activities, sludges removed from catch basins, sumps, etc. may be transported ,to the old and /or the new ash pond for,disposal. Limestone and Gypsum Piles Runoff Storm water runoff from the limestone and gypsum piles is collected in drainage ditches which are routed to the ash pond ,for treatment: During maintenance activities, sludges removed from, catch basins, sumps, etc: may be transported to the old and /or the new ash pond for disposal Storm Water Storm water runoff from the plant area, parking lots, combustion turbine area, oil storage and' handling facility and the plant's'115 KV substation is routed to the ash pond for - treatment.

Detectable levels of'these chemicals would not be expected to occur in ash pond discharges. Flue Gas Desulfurization Blowdown (Low Volume Waste) The Flue Gas Desulfurization (FGD) system directs flue gas into an absorber where a limestone (calcium carbonate) slurry is sprayed. Sulfur dioxide in the flue gas reacts with the limestone ,to produce calcium sulfate (gypsum) This system reclaims any unreacted limestone slurry to be reused in the absorber. A small blowdown stream is used to maintain the chloride concentration in the reaction tank The blowdown stream is passed through a clarifier to remove solids and the chloride concentration in the waste stream is diluted using water from Lake Julian A constructed wetland is used to remove metals, mercury and selenium specifically, and ,the treated wastewater is discharged into the secondary settling ,pond Air Preheater Cleaning (Low Volume Waste) The air preheater will be water- washed once per year or more frequently as needed The wastewater from this activity will be discharged to the ash' pond. Chemical Metal Cleaning Wastes The boilers are chemically cleaned every five -to -eight years using Tetraammonia ethylene diamine tetraaccetic acid (EDTA) solution This cleaning solution and its rinses are stored on site for disposal by evaporation,`in an operating unit's furnace. Typical cleanings would result in a waste of approximately 80,000-gallon s. Should evaporation not be used, the wastewater can be treated by neutralization and precipitation -prior to being conveyed to the old ash pond with permission of the DWQ, or to the new ash pond, or other means of disposal - Cleaning of other - 3 Carolina Power'& Light Company Asheville Steam Electric Plant National Pollutant Discharge Elimination System Permit Number NC0000396 heat exchanger surfaces may produce 5,000 - 10,000 gallons of°wastewater every three- to =five years Other Wastes Operation of the combustion turbine (CT)'generation facility may, produce turbine blade wash water, inlet filter cooling water, various condensate waters, and water from equipment and tank drains. These wastewaters will be collected in the storm water collection system of the CT site and ,routed to the ash pond During maintenance activities; sludges removed from catch basins, sumps,, etc may be transported to the old and /or the new ash pond, for disposal. - Plant Potable and Sanitary System - The supply of water for plant potable and sanitary use is obtained from the Asheville /Buncombe Water Authority system and waste from this system- is discharged to the Metropolitan Sewage District System - 230 KV Substation Storm Water - Storm water runoff'from the substation Iodated adjacent to the plant is conveyed to the old ash pond Outfall 002,­ Discharge'to Lake Julian Once- Through Cooling Water This flow provides condenser cooling water for the generating units 1 and 2. Maximum condenser flows for units 1 and 2 are 150 MGD and 156 MGD, respectively. Once- through cooling water is used to supply non - contact cooling water for the component closed cooling water system. The component closed cooling water system flows combine with unit 1 and 2 condenser flows prior to discharge to Lake Julian. Maximum component closed ,cooling water system'flows for unit 1 and 2 are 9 1 MGD and 10 2 MGD, respectively Discharge flow to Lake Julian'is calculated at,the intake, to units 1 and 2 condensers and to the, circulating water to the heat exchanger The discharge of water from the heat exchangers is routed to an ash sump. The majority of this water is further routed to the discharge of units 1 and 2 condensers Less than one percent of the flow to the ash sump is used to supply ash sluice water, preheater cleaning water; and' fire protection water. 4 Carolina Power &.Light Company Asheville Steam Electric Plant National Pollutant Discharge Elimination System Permit Number N00000396 Control of biological fouling on'heat- exchanger surfaces is accomplished by addition of sodium ;hypochlorite as required, which is usually less that 2' hours, per day per unit, with a net total residual chlorine of less than 0 2 ppm discharged during that period Cooling is accomplished by evaporation from the surface of Lake Julian and mixing and convection with lake waters _ Make up for Lake Julian is from the French Broad River, natural runoff and creek flows.

'1 § 316(b) Supplement,to NPDES Permit)VC00,00396 Reissuance Application - Clean Water Act Section 316(b) - The Asheville Steam Electric Plant is subject,to the . §316(b) Phase II regulations .Since the plant',s cooling water intake is located on a freshwater lake (Lake Julian) it is subject only to the impingement mortality reduction performance standard. This standard is a 80 — 95 % reduction in impingement mortality from the calculation baseline. The Asheville plant chooses to demonstrate that the design 'intake velocity is 0.5 feet per second or less in accordance with the compliance option presented in ,§ 125.94(a)(1)(11). This demonstration allows the plant to be deemed compliant with the impingement mortality performance standard. Additionally,, according°to the regulation the plant is not required to submit ,or be subject to the following: Comprehensive Demonstration Study (CDS) including the Proposal for Inf6rmation Collection [PIC] (§125.95) 2 Monitoring associated with any CDS component (§ 125.96) 3 Record;Keepmg and - Status Report ( §'125.97) 4 Permitting activities associated with §125.98. As part of this NPDES permit reissuance application, the Asheville Plant, is submitting the information as required by �§ 122.21(r)(1)(1i) Asheville 31,6(b) Page 1 - Demonstration of Compliance in Accordance with §125.94(a)(1)(ii) - § 125.94WQ,)(h) authorizes a facility that demonstrates their design.mtake velocity is 0.5 feet per second (fps) or less to be in compliance w`i'th -,the,impingement mortality performance standard. The cooling water intake structure located on the lake consists of an excavated cove and an intake pump structure located at the end of the cove. At the mouth of the cove is a skimmer wall which is described and depicted elsewhere in this material. The opening at the bottom of the skimmer wall allows cooler water to enter the cove and subsequently the pumps. An aerial photograph of this layout has been provided in Figure 3. Also attached is the engineering drawing forAhe skimmer wall (ELEV A -A is the cross = sectional of the skimmer wall). Since the cove is a constructed waterway it is considered part of the intake structure'. The actual inlet or opening to the cooling water intake, structure is through the bottom of the skimmer wall. Additionally, since the facility has minimal operational problems'with d °ebns .or fish' clogging the condenser tubes, ,there are no 3/8 inch screens at either the skimmer wall opening or the`mtake pumps. The pumps do have bar racks and a very,coarse mesh, fixed screen (chicken wire). The intake water velocity passing through the bottom of the skimmer wall is calculated to be 0:42 fps, based on the ratio of design flow in cubic feet per second (cfs) to the square footage of the open area. (See Figure° 4). Consequently the plant has demonstrated compliance with 40 CFR 125.94(a),(1)(ii) [design intake velocity of < 0.5 fps.]. Further rationale for compliance'is as follows: • "Design intake velocity" is defined at 125.93 to mean the speed at which the intake water passes through the open area of the intake screen or other device The skimmer - wall is an "other device" so the water passing through 'the open area of another device is < 0.5 fps. • Since ,there are no screens at the opening to the intake structure there is nothing to impinge fish. Intake veloc`i'ties are low ,and, approach velocities, should be lower so fish can maintain sustainable swimming speeds and escape being caught up in any currents that would force them into the cooling water structure However; even if fish enter into the intake structure (in this case the cove) there still is no regulatory issue since entrainment (usually applicable to non - motile, planktonic eggs and larva which are minimally found in a fresh water lake ) is not a performance standard for intake structures located on fresh water lakes ' 40 CFR�§ 125 93 defines a cooling water intake structure as the total physical structure and.any associated constructed waterways Asheville 316(b) Page 2 - River Intake - The plant operates a make =up pump on the French Broad River that serves to keep the lake at optimum level's for operation of the plant. We believe the river intake pump is not subject to the Phase II rules nor is it a factor for facility compliance The background for this position is as follows: The design of this make -up pump is currently 7.2 MGD and will be increased to 9.36 MGD to provide additional make -up to the lake due to projected Flue Gas Desulfurization (air scrubber) process water needs. It is debatable whether this intake should be considered for 316(b) purposes. This make -up pump is operated based on lake levels not necessarily�cooling water needs. The regulation states that at least 25% of water withdrawn must be used exclusively for cooling purposes, measured on an average annual basis. For the past 12 years the average annual flow of the makeup pump has been 2.24,MGD or about 31% of the design. We cannot say definitively that this 2 24 MGD is used exclusively for cooling. For example on the average there is about 2.08 MGD of lake water withdrawn that, is used for non - cooling purposes ('ash sluice, fire pump testing, and;consumed service water,). Also there is an undetermined amount of lake water- lost - through dam seepage that needs to, be made up. If we subtract the 2 07 MGD, non - cooling water uses from the flow of 2.24 MGD we find that only about 80 2 of the annual average 2 24 MGD flow from the river intake can be said to be ,used exclusively for cooling. However, this 8% is below the 25 % threshold so the Phase II regulations, would not apply. Furthermore when this makeup pump is expanded to 9.36 MGD the expansion will coincide with the need for process water for the air scrubbers, not cooling water. The air scrubbers will require an average of approximately 100 MGD of process (non - cooling) water. Therefore if we add the 1.00 MGD to the existing 2.07 MGD average consumptive (non- cooling) use we obtain a percentage of possible cooling water use of only approximately 5 %3, still below the 25% threshold. • Looking at the aggregate of the cooling system for the plant, the river intake will constitute only about 3% of the total design intake flow of the cooling system. Since the river intake design is only about 3% of the total design flow for the cooling system (assuming the river water is used exclusively as cooling water) the plant takes the position that if 97% of the cooling system intake structure is in compliance with the phase II regulations due to compliance with §125.94(a)(1)(ii), the entire system'is in compliance with the 80 - 95% impingement reduction standard.

Lake Julian is a deep, freshwater mountain lake with relatively clear waters, low nutrient concentrations, and low biological productivity The lake was created as a cooling lake by impounding Powell's Creek, a tributary of the French Broad River (see Figures 1 and.2). The lake reached full -pool elevation in June 1963 What is referred to as the discharge arm of the lake has a surface area of approximately 106.2 acres and a mean depth of approximately 13 feet; the main body of the .lake has a surface area of approximately 215 acres, a maximum depth of approximately 1,08 feet, and a mean depth of approximately 29.5 feet These two arms of the lake are physically divided by-two earthen railroad dikes. This is a fresh water lake and the salinity seldom increases above IO,mg%L. In regard to temperature regimes, cooler (hypolimnectic) water is withdrawn under the skimmer wall in the main body of the lake. During 2,004; the temperature of the surface,waters in the main body ranged from 17.6 *C to 34 5 o with a mean of 26.3 'C. The mean wateftemperature recorded during 20`04 in the main body was within the range of mean values.reported since 1992. A thermoclme develops duhng the spring and summer at about 62 -65 feet in depth. The water temperature in the discharge arm ,of the lake ranged from about 11.1 'C to 36.8 'C with a mean of 26.1 'C. In addition to the lake as the predominant cooling water source waterbody, the, plant operates a make -up pump on the French Broad River that serves to keep the lake at optimum levels for operation of the plant. At the location of the make -up pump themver is approximately 200 feerwide with depths varying depending on rainfall. On September 17, 2003 Progress Energy conducted a comprehensive bathymetry of the section of the river at the plant. The average depth was 3 17 feet with,ranges from 0.5 feet to 8.4 feet. Temperature regimes are expected to reflect ambient influences.

Based on the annual average flow (cfs /square mile) from the USGS gauging stations in Buncombe County that.have adequate historic records the annual ave rage drainage�is approximately two cfs /square, mile. Water loss from the lake water budget is attributed to evaporation, spill over the dam, seepage and consumptive use by the plant.

See Figures 1 and 2 §122.21(r)(3) — Cooling water intake structure data. (a) A narrative description of the configuration of each of your cooling water intake structures and where it is located in the water body and in the water column, - Lake Intake = A"" sheville,316(b) Page 6 The plant's intake structure on the lake consists,of an intake, cove that 'has a submerged skimmer wall at its entrance and a cooling water pump structure at the other end The skimmer wall is approximately 27.5 feet deep to the top of the submerged opening. The submerged opening has a dimension of approximately ten feet between the bottom of the entrance to the intake cove and the bottom of the skimmer wall. The submerged opening provides a total open area of approximately 1175 square feet (See Attached Drawing of Skimmer Wall and Figure 3 which is a photograph of the entire structure). -River Intake — This small structure is located on the shore of the French Broad River approximately 240 feet upstream from the confluence of Powell's Creek and thenver It consists, of a single pump housed in a ;structure that withdraws, water from the water column of the river and pumps to a settling area in the lake. (See Attached Drawing of River Intake structure) `(az) Latitude, and longitude in degrees, minutes, andseconds for each of your cooling water intake structures The entrance to the intake cove from the lake is located at Latitude 35° 28' 23" N and Longitude 82° 32' 38" W. The river pump_ structure is located at Latitude 35',28' 24" N and Longitude 82° 33" 14" W (aaa) A - narrative description of the operation of each of your cooling water intake structures, including design intake flows, daily hours of operation, number of days of the year in operation and seasonal changes, of applicable; - Lake Intake — The lake intake pump structure contains four intake bays, two for each unit Each Unit 1 intake bay contains a cooling water pump having a design capacity of 48,300 gallons per,mmute (gpm). Each Unit 2 intake bay ,contains a cooling water pump having, °a design capacity of 61;500,gpm. 'The total design capacity ofthe intake pumps is 316.2 million gallons per day (MGD) The attached graph (Figure 5) depicts the monthly average cooling water intake flow variations over the last five years. As can be. seen the flows peak and remain close to maximum, generally from May through September. The average annual flow is approximately 247 MGD. This represents a reduction credit from the design flow of about 22 %. The operation of the cooling water pumps reflect the generation need and intake water temperature. Generally -at least one pump per unit is -in operation all the time with all pumps being operational during peak generation periods in the summer months. Asheville 3'16(b) Page 7 - River Intake - In order to ensure adequate lake levels for optimum operation it is necessary to pump makeup water from the French Broad River into the lake dunng,penods of low rainfall and high evaporative losses. Other means of water loss includes seepage through the dam and consumptive use by the plant. The makeup pumps usually operate from Mayor June to October or November. The current design of"the intake pump is 5000 gpm or 7.2 MGD. This pump represents only about 2 %5 of the total cooling system design. As previously mentioned the ,design of this pump will be increased to 6500 gpm (936 MGD) or,about 3 %6 of the design flow of the cooling water intake structure pumps.

Water is pumped from the main arm of the lake through the plant condensers (heat exchangers) where it condenses the pressurized steam that is spent after contacting the turbine blades that turn the generators. Once the steam, is condensed it is returned to the boilers ,to be heated to steam again. The cooling water makes one pass through the condensers before being discharged back into the lake (termed once - through) The discharged cooling water is non - mechanically aerated prior to entering a small cooling basin. The small basin discharges into what is termed the discharge arm of the lake. The water then passes through a culvert system and enters the main body of the lake. The cooling cycle is completed when water from the lake passes beneath the skimmer wall and into the intake cove where, water is then withdrawn by the condenser cooling'water pumps The lake cooling water,intake pumps have a design flow of 316 2 MGD. Of this figure approximately 99% of the flow is used in the [cooling] system when all pumps are in operation. The cooling water pump operation is directly related to the operation of the cooling system needs. Usually in the winter months when the•intake water is cooler the need to, operate both pumps per unit i& reduced.
