CP&L 200 CP&L Drive Arden, North Carolina 28704 Subject: Issuance of NPDES Permit NPDES No. NC0000396 CP&L- Asheville Buncombe County Dear Mr. Traylor: Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued 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). Specific items in the final permit are highlighted below. In addition, response to comments submitted by both the permittee and the U.S. EPA are addressed below in the applicable sections. Outfall 001 (Ash Pond)- Effluent Sheet A(1) • Change in the quarterly toxicity test from acute to chronic due to the continuous discharge condition. The toxicity test language has also been updated to reflect new follow-up procedures to be implemented following failure events. • Addition of a pH effluent limit of 6 to 9 pH units, as required for all direct discharges (except once through cooling water) by 40 CFR 423.12. Also, the pH monitoring frequency has been increased from 2/Month to Weekly, as specified in state regulation 15A NCAC 2B.0500 for the Electrical and Gas Services Industrial Group. • Based on reasonable potential analysis, the monthly monitoring for iron is deleted, since the maximum predicted effluent concentration is less than 2% of the allowable effluent concentration. Monthly monitoring for arsenic, copper, and selenium will remain in the permit, based on maximum predicted effluent concentrations ranging from 17% to 60% of the allowable effluent concentration. Per CP&L request. an electronic copy of the RPA Procedures was transmitted separately. • In response to CP&L comment, total metals are to be analyzed in the total recoverable form. Outfall 002- (Once Through Cooling Water) - Effluent Sheet.A(2) • The thermal variance granted under Section 316(a) of the CWA has been extended for the duration of this permit. CP&L provided sufficient information to support the continuation request, and DWQ concurs that the Annual Environmental Monitoring Reports have shown no changes in the biological community of Lake Julian. Per EPA request, copies of the annual reports from 1996-1999 have been fowarded to EPA by the permittee. • Addition of weekly pH monitoring as specified in state regulation 15A NCAC 2B.0500 for the Electrical and Gas Services Industrial Group. • CP&L requested deletion of monthly copper monitoring, since copper monitoring was originally required due to suspected leaching of copper from the Unit 1 condenser tubes. These copper N.C.Division of Water Quality/NPDES Unit Phone:(919)733-5083 1617 Mail Service Center,Raleigh,NC 27699-1617 fax:(919)733-0719 Internet:h2o.enr.state.nc.us DENR Customer Service Center 1 800 623-7748 laStar NC0000396 CP&L-Asheville Page 2 tubes were replaced with stainless steel tubes in 1994. Review of monthly DMR data for the past 26 months shows one detection of copper at 23 ug/1 in November 2000, with remaining samples reported as < 10 ug/l. Based on the very low frequency of detection and replacement of copper tubes, copper monitoring has been changed from monthly to quarterly. The Division recommends that the facility consider collecting source water samples concurrently with the effluent samples, and analyzing the source water samples if a detection is reported for the effluent sample. This will provide the facility with sufficient data to evaluate whether the source water is the primary copper source. • CP&L requested the TRC limit be changed from an instantaneous maximum to a daily maximum limitation. Since EPA has issued NPDES guidance stating that the TRC limit should be applied as an instantaneous maximum, the CP&L request is denied. EPA requested that a definition of"instantaneous maximum" be included for clarification, and such a definition ("the value which shall not be exceeded at any time") has been added in the final permit on Effluent Sheet A(2). • CP&L requested that the first sentence in the next to last paragraph of Effluent Sheet A(2) be rewritten as "The permittee shall obtain authorization from the Division prior to use and discharge of any chemical additive that has not been listed in the permit application." The Division denies this request, since chemical additive authorization is conducted by the Aquatic Toxicology Unit independently of the permit renewal process. Therefore, the permittee still needs to obtain authorization for each chemical additive that has not been previously approved. Internal Outfall 004 (Chemical Metal Cleaning Wastel-Effluent Sheet A(3) • Clarification in the Supplement to Cover Sheet and Effluent Sheet A(3) that Outfall 004 is an internal outfall that may potentially discharge to the new ash pond or the old ash pond (with prior DWQ approval). The new ash pond discharges directly to the French Broad River via Outfall 001, while the old ash pond does not discharge. It should be noted that the facility has incinerated their chemical metal cleaning waste since at least 1999. • The previous permit and the draft permit included a pH limit of 6.0 to 9.0 for Outfall 004. CP&L requested that the pH monitoring and limit be removed, since this is an internal outfall which potentially discharges to the new ash pond (which is pH-limited) or the old ash pond (which does not discharge). Division discussion with EPA Headquarters (Ahmar Ciddiqui, 202- 260-1826) concluded that the pH limit was applied incorrectly, and should be reserved for the direct discharges only. Consequently, the pH limit and monitoring have been removed in the final permit. The pH limit will remain for the direct discharge from Outfall 001. • In response to CP&L comment, change the measurement frequency from "Daily" to "Per Discharge Event" to reflect the infrequent batch discharge event. If no discharge occurs during a given month, the designation "No Flow"will need to be included in the monthly DMR. Stormwater Outfalls (SW-1.2,3,4,5,61 -Effluent Sheets A(4) and A(5) • The draft permit included the addition of stormwater monitoring and reporting requirements for six stormwater outfalls located along vehicle access roads used to transport coal/oil truck deliveries to the facility. Stormwater outfalls SW-1,2,3 are located along a new access road, and stormwater outfalls SW-4,5,6 are located along the current access road. No materials loading or unloading activities will take place on the access roads, railroad storage yard, or on immediately surrounding property owned by CP&L. Subsequent to the draft permit, CP&L requested that stormwater outfall SW-3 be designated for representative stormwater monitoring, since the six stormwater outfalls are substantially identical, and Special Condition A(9)(a) provides for representative monitoring. Based on the similar industrial activity present at each outfall, the Division concurs with CP&L's request for representative outfall status using stormwater outfall SW-3. Consequently, Effluent Sheet A(4) has been modified accordingly in the final permit. • The CP&L interpretation that the annual measurement frequency in Effluent Sheet A(4) begins on the permit effective date, rather than calendar year, is correct. • CP&L requested that Special Condition A (8)- Stormwater Pollution Prevention Plan- be deleted or significantly reduced in scope, based on the fact that most areas associated with industrial I NC0000396 CP&L-Asheville • Page 3 activity drain to the ash pond and are already NPDES-permitted. In response, the Division has maintained the same stormwater requirements, but limited the applicability to the old and new access roads which will have direct discharge to surface waters. The Division concurs that stormwater from other areas with indirect discharge to the ash pond (e.g., plant area, parking lots, oil storage and handling facility) are already receiving adequate treatment and subject to relevant permit limits (e.g., TSS, oil and grease, chronic toxicity testing). Miscellaneous • Change the stream classification from WS-IV to C for French Broad River, Lake Julian, and UT Powell Creek, based on stream reclassifications on 4/1/96. • Move Special Condition F (Biocide Condition) to bottom of Effluent Sheet for Outfall 002. • The draft permit deleted generic Special Conditions G, H. I, and J, since these are not consistent with other CP&L permits or considered necessary for this facility. • EPA commented on the proposed deletion of Special Condition I (BMP Plan to control the discharge of oils and hazardous and toxic substances). In response to EPA comments, the Fact Sheet was modified to include the additional rationale for deletion. The permit includes BMP requirements for stormwater that discharges directly to state surface waters. Stormwater from other areas that do not discharge directly to surface waters (e.g., plant area, parking lots, oil storage and handling facility) as well as all plant area floor drains are routed to the ash pond, which is already permitted for relevant water quality parameters (e.g., oil and grease, TSS, chronic toxicity). Since the ash pond provides treatment prior to discharge to state surface water, additional BMP requirements are considered unnecessary to achieve water quality standards. Finally, if there is any anticipated change in the current discharge of toxic substances, the permittee is required to notify the Division according to requirements specified in boilerplate condition Part III. C- Changes in Discharges of Toxic Substances. • EPA commented on the proposed deletion of Special Condition J (which prohibits the discharge of any product registered under FIFRA). In response to EPA comments, the Fact Sheet was modified to include additional rationale for the deletion. Discussion with CP&L indicates that no insecticides or rodenticides are used onsite. The facility does hire a licensed termite applicator to treat buildings, and licensed applicators are also employed to apply herbicides for weed control. Finally, if there are any anticipated changes in the current discharge of toxic substances, the permittee is required to notify the Division according to requirements specified in boilerplate condition Part III. C- Changes in Discharges of Toxic Substances. • In response to CP&L comment, correct the citation referenced in the fourth line of Special Condition A(7) to read Section 122.21(m)(6). The citation in the draft permit was incorrect. • Correct the typographical errors in Special Condition A(9), Part(f)(2). • Several CP&L comments regarding Part II Boilerplate Language will be deferred until the next boilerplate revision. The Division agrees that the "bypass" definition is to be interpreted as the EPA definition. • Change the permit expiration date to 4/..30‘based on French Broad River Basin renewal schedule.

STORMWATER LIMITATIONS AND MONITORING REQUIREMENTS/Analytical Monitoring During the period beginning on the effective date of the permit and lasting until expiration, the Permittee is authorized to discharge stormwater from Outfalls SW-1,2,3 (drainage from new access road used to transport materials) and Outfalls SW-4,5,6 (drainage from old access road used to transport materials). Such discharges shall be limited and monitored by the Permittee as specified below: STORMWATER LIMITS MONITORING REQUIREMENTS DISCHARGE CHARACTERISTICS Units Cut-off Measurement Sample Sample Concentration) Frequency2 Type Location3 Total Flow4 MG Annual SW-3 Total Rainfall4 Inches Annual Event Duration Minutes Annual Oil and Grease Mg/I 30.0 Annual Grab SW-3 COD Mg/I 120.0 Annual Grab SW-3 TSS Mg/I 100.0 _ Annual Grab SW-3 Notes: 1. Cutoff Concentration. For each parameter, the arithmetic mean of all analytical sampling results collected during the first year of the permit shall be calculated for each individual outfall and compared to the cut-off concentrations listed. If the arithmetic mean is below the specified cut-off concentration for a given parameter, then the facility is not required to continue annual analytical monitoring for that parameter at the outfall during the term of the permit unless a significant change in facility operations or configuration occurs. If a cut-off concentration results in discontinued analytical monitoring at an individual discharge outfall,the permittee is required to maintain facility operations that ensure the continuation of stormwater runoff quality. 2. Measurement frequency. Once per year. The facility must perform analytical sampling during the first full year and last year of the permit term regardless of cut-off concentration conditions. Analytical results from sampling during the final year of the permit term must be submitted with the permit renewal application. Failure to monitor storm events in accordance with the specified frequency shall constitute a violation of this permit. 3. Sample Location. Based on the similar nature of these stormwater discharges, the permittee has been granted representative outfall status. Representative sampling will be conducted at outfall SW-3. 4. For each sampled representative storm event the total precipitation, storm duration, and total flow must be monitored. Total flow shall be either: (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the amount of build-upon (impervious) area, and the total amount of rainfall, or(c) estimated by the measurement of flow at 20 minute intervals during the rainfall event (not to exceed three hours). For purposes of the stormwater sampling required in this permit, all samples shall be collected from a discharge resulting from a representative storm event (See Part II, Section A(17)). Permit No. NC0000396 A(5). STORMWATER MONITORING REQUIREMENTS/Qualitative Monitoring Qualitative monitoring requires a qualitative inspection of each stormwater outfall, regardless of representative outfall status,for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan and assessing new sources of stormwater pollution. No analytical tests are required. Qualitative monitoring of stormwater outfalls does not need to be performed during a representative storm event.

CHRONIC TOXICITY PERMIT LIMIT(ORTRLY)-- Outfall 001 (Ash Pond) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 1.4%. The permit holder shall perform at a minimum, Quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998,or subsequent versions or"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or subsequent versions. The tests will be performed during the months of January,April,July, and October. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the two following months as described in"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised- February 1998)or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after the end of the reporting period for which the report is made.Additionally, DWG Form AT-3(original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Water Quality 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. 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 Environmental Sciences Branch at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality 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. - 1 Permit No. NC0000396 A(7). SECTION 316(A)THERMAL VARIANCE REAPPLICATION The thermal variance granted under Section 316(a)terminates on expiration of the NPDES permit. Should the permittee wish a continuation of its 316(a) thermal variance beyond the term of this permit, reapplication for such continuation shall be submitted in accordance with 40 CFR Part 125, Subpart H and Section 122.21(m)(6) not later than 180 days prior to permit expiration. Reapplication shall include a basis for continuation such as 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 plant discharges or other discharges in the plant site area which could interact with the thermal discharges; and c) there are no changes to the biotic community of the receiving waterbody which would impact the previous variance determination. A(8).STORMWATER POLLUTION PREVENTION PLAN The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the Plan, for direct discharges of stormwater to surface waters (i.e., via outfalls SW-1 through SW-6 located along the vehicle access roads). The Plan shall be considered public information in accordance with Part II, Section E.10.of this permit. The Plan shall include,at a minimum,the following items: a. Site Plan: The site plan shall provide a description of the physical facility and the potential pollutant sources which may be expected to contribute to contamination of regulated stormwater discharges. The site plan shall contain the following: (1) A general location map(USGS quadrangle map, or appropriately drafted equivalent map), showing the facility's location in relation to transportation routes and surface waters, and the name of the receiving water(s) to which the stormwater outfalls) discharges. If the discharge is to a municipal separate storm sewer system, the name of the municipality and the ultimate receiving waters, and accurate latitude and longitude of the point(s) of discharge must be shown. (2) A narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or particulate generating or control processes, and waste disposal practices. (3) A site map (or series of maps) drawn to scale with the distance legend indicating location of industrial activities (including storage of materials, disposal areas, process areas, and loading and unloading areas), drainage structures, drainage areas for each outfall and activities occurring in the drainage area, building locations and impervious surfaces, the percentage of each drainage area that is impervious. For each outfall, a narrative description of the potential pollutants which could be expected to be present in the regulated stormwater discharge. (4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3 previous years and any corrective actions taken to mitigate spill impacts. (5) Certification that the stormwater outfalls have been evaluated for the presence of non- stormwater discharges. The certification statement will be signed in accordance with the requirements found in Part II, Section B.11. b. Stormwater Management Plan: The stormwater management plan shall contain a narrative description of the materials management practices employed which control or minimize the exposure of significant materials to stormwater, including structural and non-structural measures. The stormwater management plan,at a minimum,shall incorporate the following: (1) A study addressing the technical and economic feasibility of changing the methods of operations and/or storage practices to eliminate or reduce exposure of materials and Permit No. NC0000396 processes to stormwater. Wherever practicable the permittee should consider covering storage areas, material handling operations, manufacturing or fueling operations to prevent materials exposure to stormwater. In areas where elimination of exposure is not practicable, the stormwater management plan shall document the feasibility of diverting the stormwater runoff away from areas of potential contamination. (2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, or storage of hazardous materials to prevent leaks and spills from contaminating stormwater runoff. If the secondary containment devices are connected directly to stormwater conveyance systems, the connection shall be controlled by manually activated valves or other similar devices [which shall be secured with a locking mechanism] and any stormwater that accumulates in the containment area shall be at a minimum visually observed prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated. Records documenting the individual making the observation, the description of the accumulated stormwater and the date and time of the release shall be kept for a period of five years. (3) A narrative description of Best Management Practices (BMPs) to be considered such as, but not limited to, oil and grease separation, debris control, vegetative filter strips, infiltration and stormwater detention or retention, where necessary.

The limitation is identified as "Monthly Average" in Part I of the permit. b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such week. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the week and then dividing this sum by the number of days the tests were reported. This limitation is identified as 'Weekly Average" in Part I of the permit. c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit. d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar year on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the year and then dividing this sum by the number of days the tests were reported. This limitation is defined as "Annual Average" in Part I of the permit. S 1 Boilerplate Part II Page 2 of 18 6. Concentration Measurement a.

The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average monthly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit. b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average weekly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This limitation is identified as'Weekly Average" under"Other Limits" in Part I of the permit. c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If only one sample is taken during any calendar day the concentration of pollutant calculated from it is the "Maximum Daily Concentration".

The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such year (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day . The average yearly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is identified as "Annual Average" under "Other Limits" in Part I of the permit. e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is considered to be the "daily average concentration" for the discharge. It is identified as "daily average" in the text of Part I. f. The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit. g. A calendar quarter is defined as one of the following distinct periods: January through March, April through June,July through September. and October through December. • • Boilerplate Part II Page 3 of 18 7. Other Measurements a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded during the calendar month. b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. c. A"continuous flow measurement" is a measure of discharge flow from the facility which occurs continually without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. 8. Types of Samples a. Composite Sample: A composite sample shall consist of: (1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the present gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow. In accordance with (1) above, the time interval between influent grab samples shall be no greater than once per hour, and the time interval between effluent grab samples shall be no greater than once per hour except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals evenly spaced over the 24 hour period which are equal in number of hours to the detention time of the system in number of days. However, in no case may the time interval between effluent grab samples be greater than six (6) hours nor the number of samples less than four (4) during a 24 hour sampling period. b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes: the grab sample can be taken manually. Grab samples must be representative of the discharge or the receiving waters. 9. Calculation of Means a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual values. b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one (1). c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its respective flow divided by the summation of the respective flows. Boilerplate Part II Page 4 of 18 10. Calendar Day A calendar day is defined as the period from midnight of one day until midnight of the next day.

Permit Actions This permit may be modified, revoked and reissued, or terminated for cause. The filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any permit condition. 13. Permit Modification, Revocation and Reissuance, or Termination The issuance of this permit does not prohibit the permit issuing authority from reopening and modifying the permit, revoking and reissuing the permit, or terminating the permit as allowed by the laws, rules, and regulations contained in Title 40, Code of Federal Regulations, Parts 122 and 123; Title 15A of the North Carolina Administrative Code, Subchapter 2H .0100; and North Carolina General Statute 143-215.1 et. al. 14. Previous Permits All previous National Pollutant Discharge Elimination System Permits issued to this facility, whether for operation or discharge, are hereby revoked by issuance of this permit. (The exclusive authority to operate this facility arises under this permit. The authority to operate the facility under previously issued permits bearing this number is no longer effective. The conditions, requirements, terms, and provisions of this permit authorizing discharge under the National Pollutant Discharge Elimination System govern discharges from this facility. SECTION C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS 1. Certified Operator Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the facility by the Certification Commission, the permittee shall employ a certified wastewater treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities. Such operator must hold a certification of the grade equivalent to or greater than the classification assigned to the wastewater treatment facilities by the Certification Commission. The permittee must also employ a certified back-up operator of the appropriate type and any grade to comply with the conditions of Title 15A NCAC Chapter 8G .0200. The ORC of the facility must visit each Class I facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and must properly manage and document daily operation and maintenance of the facility and must comply with all other conditions of Title 15A, NCAC Chapter 8G .0200. Once the facility is classified, the permittee shall submit a letter to the Certification Commission which designates the operator in responsible charge within thirty days after the wastewater treatment facilities are 50% complete. 2. Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit. Boilerplate Part II Page 12 of 18 3. Need to Halt or Reduce not a Defense It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit. 4. Bypassing of Treatment Facilities a. Definitions p) "Bypass" means the known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. (2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations • to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs c. and d. of this section. c. Notice p) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and affect of the bypass. (2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II, E. 6. of this permit. (24 hour notice). d. Prohibition of Bypass (1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C)The permittee submitted notices as required under Paragraph c. of this section. (2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects, if the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph d. p) of this section. Boilerplate Part II Page 13 of 18 5. Upsets a. Definition. "Upset " means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph c. of this condition are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. c. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the cause(s) of the upset; (2)The permittee facility was at the time being properly operated; and (3)The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit. (4) The permittee complied with any remedial measures required under Part II, B. 2. of this permit. d. Burden of proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof. 6. Removed Substances Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as to prevent any pollutant from such materials from entering waters of the State or navigable waters of the United States. The permittee shall comply with all existing federal regulations governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued by the Permit Issuing Authority for the utilization/disposal of sludge may be reopened and modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The permittee shall comply with applicable 40 CFR Part 503 Standards for the Use and Disposal of Sewage Sludge (when promulgated) within the time provided in the regulation, even if the permit is not modified to incorporate the requirement. The permittee shall notify the Permit Issuing Authority of any significant change in its sludge use or disposal practices. 7. Power Failures The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation, Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the discharge of untreated or inadequately treated wastes during electrical power Boilerplate Part II Page 14 of 18 failures either by means of alternate power sources, standby generators or retention of inadequately treated effluent. SECTION D. MONITORING AND RECORDS 1. Representative Sampling Samples collected and measurements taken, as required herein, shall be characteristic of the volume and nature of the permitted discharge. Samples collected at a frequency less than daily shall be taken on a day and time that is characteristic of the discharge over the entire period which the sample represents. All samples shall be taken at the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins or is diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed without notification to and the approval of the Permit Issuing Authority. 2. Reporting Monitoring results obtained during the previous month(s) shall be summarized for each month and reported on a monthly Discharge Monitoring Report (DMR) Form (DEM No. MR 1, 1.1, 2, 3) or alternative forms approved by the Director, DEM, postmarked no later than the 30th day following the completed reporting period. The first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Duplicate signed copies of these, and all other reports required herein, shall be submitted to the following address: Division of Water Quality Water Quality Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 3. Flow Measurements Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements are consistent with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a maximum deviation of less than 10% from the true discharge rates throughout the range of expected discharge volumes. Once-through condenser cooling water flow which is monitored by pump logs, or pump hour meters as specified in Part I of this permit and based on the manufacturer's pump curves shall not be subject to this requirement. 4. Test Procedures Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136; or in the case of sludge use or disposal, approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless other test procedures have been specified in this permit. To meet the intent of the monitoring required by this permit, all test procedures must produce minimum detection and reporting levels that are below the permit discharge requirements and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. If no approved methods are determined capable of • Boilerplate Part II Page 15 of 18 achieving minimum detection and reporting levels below permit discharge requirements, then the most sensitive (method with the lowest possible detection and reporting level) approved method must be used. 5. Penalties for Tampering The Clean Water Act provides that any person who falsifies, tampers with, or knowingly renders inaccurate, any monitoring device or method required to be maintained under this permit shall, upon conviction, be punished by a fine of not more than $10,000 per violation, or by imprisonment for not more than two years per violation, or by both. If a conviction of a person is for a violation committed after a first conviction of such person under this paragraph, punishment is a fine of not more than $20,000 per day of violation, or by imprisonment of not more than 4 years, or both. 6. Records Retention Except for records of monitoring information required by this permit related to the permittee's sewage sludge use and disposal activities, which shall be retained for a period of at least five years (or longer as required by 40 CFR 503), the permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by this permit, for a period of at least 3 years from the date of the sample, measurement, report or application. This period may be extended by request of the Director at any time. 7. Recording Results For each measurement or sample taken pursuant to the requirements of this permit, the permittee shall record the following information: a. The date, exact place, and time of sampling or measurements; b. The individual(s) who performed the sampling or measurements; c. The date(s) analyses were performed; d. The individual(s) who performed the analyses; e. The analytical techniques or methods used; and f. The results of such analyses. 8. Inspection and Entry The permittee shall allow the Director, or an authorized representative (including an authorized contractor acting as a representative of the Director), upon the presentation of credentials and other documents as may be required by law, to; a. Enter upon the permittee's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this permit; b. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this permit; c. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this permit; and d.

CP&L requests a copy of the procedure for the RPA. PART I Section A(1). — Effluent Limitations And Monitoring Requirements •✓CP&L assumes that the "total" metals listed under Effluent Characteristics are to be analyzed in the total recoverable form. Section A(2). — Effluent Limitations And Monitoring Requirements OCP&L requests that the requirement to monitor and report total copper for Outfall 002 on Cti a quarterly basis be eliminated. Attached are the total copper results for the time period ,C)^ect , of January 1994 to May 2001. During this time period there have been only 3 data �►, points above the State Action Level for copper (7 ppb) out of 89 total data points. Most of the data was below the reporting limits. With only 3 data points above the State Action Level for copper, CP&L feels that an elimination of the monitoring requirement for total copper is appropriate. 110 •/CP&L requests that the first sentence in the next to the last paragraph be rewritten as "The permittee shall obtain authorization from the Division prior to use and discharge of V49 4- any chemical additive that has not been listed in the permit application". 4' �, . NQ. A Section A(3). — Effluent Limitations And Monitoring Requirements oCP&L requests the pH monitoring and limit for Outfall 004 be removed. Metal cleaning waste is an internal outfall to either the new or old ash pond (with DWQ permission). pH limits and monitoring is required of the effluent of the new ash pond, Outfall 001. The old ash pond does not discharge. � •✓ Metal cleaning wastes are produced in batches. CP&L feels that it is more appropriate iS�6 / �iV for the measurement frequency to be per batch or per event rather than daily. Section A(4) — Stormwater Limitations and Monitoring Requirements/Analytical Monitoring t e�,k •✓The annual /once per year (first full year of permit term) measurement frequency is �l interpreted to mean within the first 365 days (one year)that elapse after the day on G which the permit is effective. For example, if the permit is effective on August 1, 2001, we would have until July 31, 2002 to conduct the measurement. 1 Asheville Steam Electric Plant Draft NPDES Permit Comments Section A(7) Section 316(a) Thermal Variance Reapplication ��� k •V The citation referenced in the fourth line cannot be found. The correct citation is 4�r(6r' probably Section 122.21(m) (6). Section A(8) — Stormwater Pollution Prevention Plan •tlThis section of the permit appears to be the standard language for storm water program development at industrial sites. However, the scope of the regulated storm water discharges at the Asheville plant is certainly less significant than what was intended to be addressed by the DWQ standard language. Any storm water program development activities at the Asheville plant would address only the new and old access roads. All other areas associated with industrial activity for the Asheville Plant drain to the ash pond which is already permitted. CP&L believes that the storm water discharge monitoring should suffice for addressing the storm water discharges from the roads. CP&L, therefore, requests that this section of the permit be deleted or significantly reduced in scope. We would be glad to meet with the DWQ staff to discuss this issue. Section A(9) — Stormwater Minimum Monitoring and Reporting Requirements •✓Part a. of this section allows a facility to petition for representative outfall status. The six stormwater outfalls for the Asheville Plant are substantially identical. CP&L, hereby requests that SW-3 be used for representative stormwater monitoring. ,io ��� Part d. requires that monitoring results be submitted no later than January 31 for the re previous year in which sampling was required to be performed. Using the example in Section A(4) above, CP&L understands that the monitoring results could be submitted no later than January 31, 2003. •V Part f. (2) should contain the word "flushing" after"waterline and fire hydrant." Additionally, it is believed that"habits" should be "habitats." Part II Page 1 of 18 cttp • /DEM in item 2 needs to be replaced with DWQ. Part II Page 10 of 18 • Item 11 - Signatory Requirements, paragraph a. (1) has been modified in the Federal Regulations. This provision in the DWQ boilerplate should also be updated accordingly. 2 Asheville Steam Electric Plant Draft NPDES Permit Comments Part II Page 12 of 18 •/Item 4 — Bypassing of Treatment Facilities, paragraph a.(1) The DWQ defines a bypass as "the known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating %5/ mode for the facility." Since neither the NC Statutes nor the DENR regulations contain a definition of bypass, (other than a bypass in reference to pretreatment) the definition of bypass should default to the federal definition. The EPA defines bypass as "...the intentional diversion of waste streams from any portion of a treatment facility." Although the difference between these definitions may appear to be subtle, the meaning of the definition in the proposed permit in regard to the reporting requirements and liabilities associated with the NPDES permit are, in CP&L's belief, significant and excessive beyond that authorized by law and regulation. CP&L requests that the proposed definition in the proposed permit be replaced by the EPA definition or that the DWQ inform CP&L that the proposed definition is to be interpreted as the EPA definition. 3 • Asheville Steam Electric Plant Draft NPDES Permit Comments Outfall 002- Copper Data 1994 January <20 ppb February <20 ppb March <20 ppb April <20 ppb May <20 ppb June <20 ppb July <20 ppb August <20 ppb September <20 ppb October <20 ppb November <20 ppb December <20 ppb 1995 January <20 ppb February <20 ppb March <20 ppb April <20 ppb May <20 ppb June <20 ppb July <20 ppb ygust <20 ppb September 7 ppb October 3 ppb November 2.6 ppb December 2.3 ppb 1996 January 2.3 ppb February 2.7 ppb March 2.0 ppb April 3.8 ppb May 2.2 ppb June 2.4 ppb July 2.3 ppb August 2.8 ppb September 2.2 ppb October 1.9 ppb November 2.5 ppb December 22 ppb 1997 January 2.5 ppb February 1.7 ppb March 3.1 ppb April 2.4 ppb May 1.9 ppb June <10 ppb July <10 ppb August <10 ppb September <10 ppb October <10 ppb November <10 ppb December <10 ppb 4
