Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended. 33 L:SC 1251, et. seq. 5. Nlass/Da% Measurements a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month. It is therefore, an arithmetic7 mean found by adding the weights of the pollutant found each day of the month and then dividing this sum by the number of days the tests were reported. The limitation is identified as "Monthly Average' in Part I of the permit. b. The "week]; 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. 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 vear. 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. Part II Page 2 of 14 6. Concentration Measurement a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month (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 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". It is identified as "Daily Maximum" under "Other Limits" in Part I of the permit. 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" to 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. Part II Page 3 of 14 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 now 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. AM a j&T- .1 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 ereater 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). Part II Page 4 of 14 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. 10. Calendar Dav A calendar day is defined as the period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. 11. Hazardous Substance A hazardous substance means any substance designated under 40 CFR Part 1 ] 6 pursuant to Section 311 of the Clean Water Act. 12.

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, Chapter 8A .0202. 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, Chapter 8A .0202. Once the facility is classified, the lermittee 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. Pan II Page 8 cf 14 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. .., m. . t+ 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. vmsina of Treatment Facilities a. Definitions (1) '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 (1) 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 Part II Page 9 of 14 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. (1) of this section. 5. Up et 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 Hho 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 Staics. The permittee shall comply with all existing federal Part II Page 10 of 14 regulations governing the disposal of sewage sludge. Upon promulgation of 40 CFR Pan 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 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.

Flowers Plant Manager December 27, 1995 _,, WL K'XS In accordance with the notification requirements found at Part II E.9 of the subject NPDES permit, the purpose of this letter is to document the event that occurred on December 26, 1995 and reported to you on December 27, 1995. On December 26, 1995, at approximately 8:00 A.M., water from a leak at a coupling in an ash transport water line was noticed to be entering the discharge canal. The leaking water had entered into the ditch that contains the ash transport water lines and was entering the discharge canal from this ditch. Subsequent investigation discovered that the source of the water was a sump pump from a sump in the ash handling area. The leak was repaired at approximately 12:15 PM on the same day. It is believed that approximately 200 (two hundred) gallon of this sump water entered the discharge canal where it was overwhelmingly diluted by approximately 1 billion gallons of discharge water. Visual observation concluded that there was no impact to the effluent in the discharge canal, as expected. If there are any questions regarding this information, please contact Richard C. Yates, (919) 546-7777 or Mr. Fred Holt at (919) 546-5048. RWW:mp LAB/NPD3425.eds Enclosures Sincerely, A�g 4� Albert O.

Flowers Plant Manager September 22, 1995 o L-_ On August 28, 1995, Mr. Rick Yates of Carolina Power & Light Company's Environmental Services Section contacted Mr. Steve Mitchell of your office to discuss CP&L's plan to temporarily pump makeup water for the Roxboro Plant's Unit 4 cooling tower directly from Hyco Reservoir. Normally, this makeup water is withdrawn at a continuous rate of approximately 4000 gallons per minute from the plant's cooling water discharge canal to offset evaporative and blowdown losses from the cooling tower. The withdrawal of this makeup water from the lake rather than the canal for approximately one month is designed to evaluate the potential benefit of using cooler makeup water on the operational efficiency of the power plant. Mr. Mitchell concluded that no approval is required from the North Carolina Division of Environmental Management for the temporary withdrawal; however, he requested that this letter be sent to you to describe the action planned by CP&L. Additionally, Mr. Mitchell suggested that CP&L consult with the North Carolina Division of Water Resources (NCDWR) to determine what notification was required by that agency. The NCDWR concluded that CP&L could proceed with its plan and submit a followup letter to supplement the water withdrawal registration form currently on file with that agency for the Roxboro Plant.

The cofferdam will be removed later this week, and the retention pond system will return to its normal function. No harm to the environment or human health was observed during or following the incident. Prior to the discovery of the leak, the discharge from the retention pond was tested for toxicity on five occasions during 1994 as required by the NPDES permit. The toxicity tests performed on the pond's effluent on each of those occasions indicated no acute toxicity.

The basin designated in the Roxboro Plant's last permit renewal application for treatment of chemical cleaning wastes for discharge via outfall serial 009 to the plant's ash pond (outfall serial 002) has not been used for its intended purpose since July 30, 1987, when the North Carolina Division of Environmental Management (NCDEM) amended the Roxboro Plant's air permit to allow incineration of the chemical cleaning wastes in the facility's boilers. Therefore, CP&L respectfully requests that the NCDEM modify the facility's NPDES permit to delete outfall serial number 009. As you directed Mr. Rick Yates of CP&L's Environmental Services Section staff during a telephone conversation on July 14, 1995, this request is sent to your attention with a $400.00 check (Enclosure 1) for the required application processing fee for a permit modification.

Flowers Plant Manager July 6, 1995 Subject : Carolina Power & Light Company (CP&L) Roxboro Steam Electric Plant National Pollutant Discharge Elimination System (NPDES) Permit No. NC0003425 Dear Mr. Schuster: In accordance with Part II, E 9 (a) of the above referenced NPDES Permit, on June 29, 1995, Mr. S. Mitchell of the Raleigh Regional Office of the North Carolina Division of Environmental Management (NC-DEM) was notified via telephone by Ms. J. P. Cooke of CP&L's Environmental Services Section that an overflow of the facility's Unit 3 cooling tower basin had occurred. Pursuant to a June 30, 1995 agreement between Ms. J. P. Cooke and Ms. J. E. Garrett, Water Quality Supervisor - Raleigh Regional Office of NC-DEM, the required written follow-up notification is being provided by July 7, 1995. On June 29, 1995, excessively heavy rainfall resulted in an inordinately large amount of inflow into the Unit 3 cooling tower basin. The inflow into the cooling tower basin caused the basin to fill rapidly and subsequently overflow into the facility's intake canal. The overflow ceased and the basin returned to normal operating level when the rainfall stopped. Recurrence is highly unlikely. No harm to the environment or human health occurred during or after the overflow. If you have any questions regarding this information, please contact Mr. G. H. Ohmstede at (910) 597-6137 or Mr. R.

Flowers Plant Manager July 20, 1995 Subject : Response to Compliance Evaluation Inspection Carolina Power & Light Company (CP&L), Roxboro Steam Electric Plant National Pollutant Discharge Elimination System (NPDES) Permit No. NC0003425 Person County Dear Ms. Garrett: Based on your agency's inspection of our facility on June 15, 1995, changes listed below have been implemented to strengthen our NPDES program at the Roxboro Steam Electric Plant. These changes address the observations made in your letter dated June 22, 1995. In response to Item 2, we have set up an annual calibration program for all flow meters with documentation of the calibrations in the ORC's daily log book. This year's calibrations will be completed before August 31, 1995. Item 3 addresses the need for a separate log book for the calibration records for the chlorine analyzer. According to the manufacturer of this instrument, only a zero calibration is necessary before each use. This zero calibration is performed before each use and is recorded in our daily operational log for the Unit 4 cooling tower, Outfall #005. At the time of the inspection, it was unclear whether there was a need to bracket expected ranges because the manufacturer's operation manual was not available. We will continue to zero this instrument before each use and record the results on the daily operator log sheet. To address Item 4, all certified laboratories used for conducting our analyses will be noted on each DMR. This practice has been reflected on the June 1995 DMR's. As communicated on March 31, 1995 (see Attachment), signatory authority was transferred from Dr. G. J. Oliver to the Plant Manager at Roxboro Plant. Since I am the Plant Manager of the Roxboro Plant, I have the authority to sign the DMR's. If you have any questions regarding this information, please contact Mr. R. C. Yates at (919) 546-7777.

Mitchell of the Raleigh Regional Office of the North Carolina Division of Environmental Management (NC-DEM) was notified via telephone by Ms. J. P. Cooke of CP&L's Environmental Services Section that an overflow of the facility's Unit 3 cooling tower basin had occurred. Pursuant to a June 30, 1995 agreement between Ms. J. P. Cooke and Ms. J. E. Garrett, Water Quality Supervisor - Raleigh Regional Office of NC-DEM, the required written follow-up notification is being provided by July 7, 1995. On June 29, 1995, excessively heavy rainfall resulted in an inordinately large amount of inflow into the Unit 3 cooling tower basin. The inflow into the cooling tower basin caused the basin to fill rapidly and subsequently overflow into the facility's intake canal. The overflow ceased and the basin returned to normal operating level when the rainfall stopped. Recurrence is highly unlikely. No harm to the environment or human health occurred during or after the overflow. If you have any questions regarding this information, please contact Mr. G. H. Ohmstede at (910) 597-6137 or Mr. R.

The subject inspection was performed by Ted Cashion of my staff and Kristie Robeson of the Aquatic Toxicity Group on June 15, 1995. The cooperation of Greg Ohmstede and Billy Carson was appreciated. Findings during the inspection were as follows: 1. A review of laboratory reports and DMR data showed consistent reporting of results. 2. Instrument flow measuring devices are required to be calibrated at a minimum of once per year. It was noted during the inspection that the flow meter for outfall 002 was last calibrated approximately 2 years ago. Please document future calibrations of each meter. 3. A log book documenting calibration of the pH meter is maintained as required. No log documenting chlorine meter calibration is maintained. Please document calibration before each use using standards that bracket the expected values. If you have questions on this subject please contact William Edwards of the Laboratory Certification Group at 919-733-3908. 4. Please indicate on DMRs each certified laboratory that performs analyses for the facility. 5. All outfalls were observed during the inspection and appeared free of excess solids and foam. No evidence of detrimental impact to the environment was apparent. 3800 Barrett Drive, Suite 101, Raleigh, North Carolina 27609 Telephone 919-571-4700 FAX 919-571-4718 An Equal Opportunity Affirmative Action Employer 60%recycled/ 10%post-consumer paper Dr. Oliver June 22, 1995 Page 2 6.

Flowers Plant Manager May 1, 1995 As reported to Mr. Randy Jones of the NCDEM Raleigh Regional Office on April 26, 1995 lubricating oil was discovered seeping into below grade electrical vaults and an adjacent hole at CP&L's Roxboro Plant. The oral notification provided on April 26th is responsive to that required by NCGS § 143-215.85 and that likewise required in 15A NCAC §2L.0106. The oil release was discovered in the plant's coal handling area. The measures being taken to contain and remove the discharge are as follows: Free product recovery began on April 26th. Similarly, work was initiated to determine the extent and cause of the oil release. We believe the source of the oil leak was a buried pipeline. We have isolated that line and removed it from service. If you have any questions or would like to discuss this further, please call me at (910) 597-6101 or Tom Crawford in Raleigh at (919) 546-2673.

Ennis of my staff reported to you by telephone on March 7, 1994, an oil spill that occurred that same day at the Roxboro Steam Electric Plant near Roxboro, North Carolina. Approximately 100-150 gallons of No. 2 fuel oil (non -PCB) were released when the oil header system became overpressurized and blew out the gaskets on the fuel oil meters. The oil release resulted from an abnormal condition which is not expected to recur. Appropriate plant personnel were advised to avoid such abnormal maintenance conditions. All oil was contained in plant containment or cleanup systems and no visible traces were released to the environment. The oil was recovered/absorbed and appropriately disposed of with no harm to human health or the environment.

Since that time, the Company has chosen to revise the internal flow path of one of the waste streams identified in the renewal application. As a result, the permit will no longer require OutW1 007, the discharge from the oil/water seperator serving the oil loading area and discharging to the heated water discharge canal. CP&L is hereby modifying the permit renewal application to reflect that change. Specifically, CP&L is prepared to divert the oily waste drains from the fuel oil loading area to the plam's main oily waste collection and disposal system. The waste water from the oil loading area will then be combined with other oily waste, treated by existing oil/water separators that have ample capacity, and pumped to the ash pond along with the other low volume waste water. A revised waste water flow diagram is enclosed for your reference. Other than adding the additional treatment of the ash pond for that small additional quantity of low volume waste, no additions or modifications of treatment processes is involved in this change. For the reasons given above, please modify the renewal permit to delete outfall 007. 1f you have any questions or require additional information, please contact Cam Wheeler at 546-6725 in our general office.

Either all or part of the elements enumerated in the Periodic Table, either singularly or in any combination, may from time to time be contained in the discharge. outfall 001 - Discharge Canal At the point that the discharge canal enters Hyco Reservior, it contains the flows from several waste streams, including once - through cooling water, the discharge of a small oil/water separator, and the effluent from the ash pond, which in turn receives and treats the combined flows from the ash transport system, the low volumes wastes collection system, chemical metal cleaning wastes, cooling tower blowdown, and the storm water runoff from the fly ash landfill. Detailed descriptions of these individual waste streams are below. once through coo i g water Condenser cooling water (CCW) for Units 1, 2, and 3 is withdrawn from the intake canal and is discharged to the discharge canal. Flows for Units 1, 2, and 3 are 236 MGD, 323 MGD, and 512 MGD respectively. Cooling is accomplished by evaporation from the surface of Hyco Reservoir and mixing and convection with reservoir waters. During the summer months, Unit 3 CCW is routed through mechanical draft cooling towers where most of the waste heat is removed by evaporation before that water is discharged to the reservoir via the discharge canal along with the CCW of Units I and 2. Inside the plant, CCW is used to supply non - contact cooling water for the component closed cooling water system, that flow combines with the CCW within the plant prior to discharge to the canal. Control of biological fouling on heat exchanger surfaces during the warmer months is accomplished by addition of chlorine gas as required, which is usually less than 2 hours per day per unit, with a net total residual chlorine of less SAN-26-1994 12:09 FROM r 1 WATER QUALITY SECTION TO RRO P.05i0? than 0.2 ppm discharged during that period. LQw Volume Wastes (oil/Water Separator) The fuel oil unloading area near the oil tanks is bermed to prevent accidental release of oil to the reservoir. Any contaminated storm water from this area is routed through a oil water separator for treatment and then discharged to the discharge canal. Ash Pond Discharge The ash pond receives ash transport water, low -volume wastes, runoff from the ash landfill, blowdown from the Unit 4 cooling tower, and is planned to receive sewage treatment plant effluent. The pond provides treatment by sedimentation, oxidation, neutralization, equalization, and adsorption. Since this is a major portion of the waste water fron this facility and there is substantial dilution of this waste stream with the once -through cooling water prior to reaching outfall 003, a priority pollutant analysis of the ash pond discharge (outfall 002 in the current permit) is attached. Ash Transport Water Water for sluicing ash to the ash pond is withdrawn from the CCW system as needed. Normally, only bottom ash is conveyed to the ash pond in this manner; fly ash is handled dry by a pneumatic system and is landfilled on site or sold. If the dry fly ash handling system is out of service during plant operating periods, fly ash will be sent to the ash pond via the ash sluicing system until the dry system is restored. Such occurrences are expected to be infrequent and brief. Low Volume Wastes Boiler make-up water is withdrawn from the CCW system and filtered, softened, and evaporated for treatment. In some cases, when unit evaporators are not in service, boiler water is treated by deionization. Boiler water is treated with ammonia, hydrazine and sodium hydroxide. Boiler and evaporator blowdown is sent to the ash pond via the low volume wastes collection system (LVWS); these are special drains in the plant that flow by gravity to collection sumps and are the pumped to the ash pond. Ethylene glycol is used during cold weather for freeze protection of some equipment and may be discharged to the LVWS, as is some molybdate waste from the closed cooling water system, during periods of maintenance. The plant's demineralizers are regenerated using sulfuric acid and sodium hydroxide. When this equipment is rinsed, small amounts of these chemicals are discharged to the low 3RN-26-1994 12:10 FROM r'cM WATER QUALITY SECTION TO RRO P.06/07 7 volume system. Essentially all plant equipment, floor drains, and ash hopper seal water overflow also discharge to the LVWS. Cooling Tower Slowdown Normally, bottom ash transport water withdrawals from the Unit 4 CCW system is sufficient to control total dissolved solids (TDS) in the cooling towers. However, at times when that is not adequate, some additional blowdown to the ash pond may be required to keep. concentrations of TDS to within proper operating limits. Unit 4 is the only unit that would produce cooling tower blowdown. Chemical Metal Cleaning Waste The boilers and other heat exchanger surfaces are chemically cleaned every five to seven years using a mild citric acid solution. This cleaning solution and rinses are stored on site for disposal by incineration in a operating unit's boiler. Typical boiler cleanings would result in a waste of approximately 100,000 - 200,000 gallons every two to three years. Should incineration not be used, the waste will be routed to a treatment basin for neutralization and precipitation prior to discharge to the ash pond. Cleaning of other heat exchanger surfaces may produce 5,000-10,000 gallons every three to five years. Stormwater Runoff from Ash Landfill The ash landfill, which was constructed as part of the conversion of the ash handling system at the plant from a wet handling system to a dry system, began operation in 1988 and encompasses approximately 315 acres. The landfill is located at the site of the old east ash pond and was constructed so that all portions of the landfill, both active and inactive, drain to the current ash pond. Treated Domestic Sewage The Roxboro Plant proposes to route the treated effluent from the domestic sewage treatment facilities (see description of outfall 006) to the ash pond. The additional treatment afforded by the ash pond will provide an extra measure of protection for the quality of Hyco Reservoir. . The additional adsorption, sedimentation, and oxidation provided by the pond and the ash will provide a very reliable level of additional treatment for the domestic sewage. ;AN-26-1994 12:10 FROM r-M WATER QUALITY SECTION TO RRO P.07i07 outfall 008 - Domestic Sewage Domestic sewage from the approximately 325 employees on site and occasional extra contract maintenance employees is treated by an extended aeration treatment plant consisting of a screen, comminuter, surge tank, aeration tank, clarifier, chlorine contact chamber, and a sludge holding tank. As a backup to the extended aeration system described above, there is a septic tank, subsurface sand filter, and chlorine dosing chamber that provide treatment if the other system is temporarily out of service, and discharges to the discharge canal. Storm water runoff from the coal pile and the other coal handling areas of the plant is routed to a retention pond for treatment by sedimentation and equalization. The pond is designed to store in excess of the 10-year/24-hour storm event. Releases are controlled by a standpipe and skimmer discharge structure.

As a result, the following comments and/or recommendations are made: 1. Screenings from the bar screen are normally not removed. The screenings are very infrequent and generally do not build- up in significant amounts to require attention. However, the material that is discarded is sent to the county landfill. 2. All other treatment units appeared to be operating satisfactorily. 3. NCAC 2B .0505 (b)(1) requires annual calibration of the flow meters. Calibration information must be kept on file for a period of three years. Also, this office recommends that your flow meter be checked weekly by an operator and the respective information recorded in a log book. This will insure that the flow meters at your facility are calibrated and are recording within the +10% accuracy limit required by your NPDES Permit. 4. The effluent for both the package plant (outfall 008) and the coal pile runoff (outfall 006) were free from visible solids. These two outfalls discharge into the Hyco Lake proper. (Note: from visual inspection the coal pile runoff (006) holding pond appeared to have a slight bluish hue.) P.O. Box 29535.

The parametric data review was based on your NPDES permit NC0003425 which expired July 31, 1991. Though expired, this permit was deemed valid as a result of EPA's failure to approve a subsequent permit for the subject facility. 8. During the inspection some of the self -monitoring bench notes were reviewed. No discrepancies between bench data and reported value data were found. 9. A log book of results for the C12 spectrophotometer was maintained. However, no instrument calibration information Mr. George Oliver, Ph.D. January 10, 1994 Page-3- was available. In order to document calibrations, you need to develop a log where blanks and standards calibration data can be recorded.

At that time, the plant was found in compliance with the NPDES permit. In the letter, there were two recommendations that CP&L felt should be addressed and a response sent back to the Division of Environmental Management. The two recommendations were annual calibration of the flow meters (No. 3) and instrument calibration (No. 9). Item No. 3 NCAC 2B .0505 (b)(1) requires annual calibration of the flow meters. Calibration information must be kept on file for a period of 3 years. Also this office recommends that your flow meter be checked weekly by an operator and the respective information recorded in a log book. This will ensure that the flow meters a the facility are calibrated and recorded within t 10% accuracy required by your NPDES permit. Response An annual calibration has been established for the flow meter on outflow 008. Calibration of this flow meter indicated a maximum deviation of f2.7%. A bound, numbered log has been obtained for the operator -in -responsible charge. This was established on December 22, 1993. It contains a daily entry for operator sign -in, condition of the plant and actions taken to ensure its proper operation. Mr. K. Schuster 2 APR 13 M Item No. 9 A log book for the results of the C12 spectrophotometer was maintained. However, no instrument calibration information was available. In order to document calibration you need to develop a log where blanks for standard calibration data can be recorded. Response To address Item No. 9, a log book has been established to record data related to C12 blanks and standard calibration curve data. Discharge of chlorinated water has been limited in the past due to problems with the feed system. With the upgrade of these systems, monitoring and adequate recordkeeping of this parameter is imperative as well as its documentation. We hope this has been responsive to your need to close out the NPDES compliance evaluation inspection. Also we would like to thank Mr. Danny Smith and Ms. Judy Garrett for their time in helping to make sure that Roxboro Plant stays current and in compliance with its NPDES permit. Very truly yours, G.

At Mr. Mitchell's direction, this letter is being submitted to describe the circumstances related to the confirmation of the leak and its subsequent repair. At about 2:00 p.m. on Friday, December 9, 1994, Roxboro Plant staff observed a small vortex at the water surface in the coal pile retention pond adjacent to the discharge standpipe indicating a small subsurface leak in the standpipe. The water level in the pond was below the level of normal discharge from the standpipe. The plant staff was proceeding with plans to isolate the suspected leak and make any necessary repairs. Mr. Mitchell recommended that CP&L complete its assessment on Monday, December 12, 1994, and then call him again to describe the extent of the problem and CP&L's followup action, if necessary. On Monday, December 12, 1994, the plant staff determined that there was a leak of an estimated 3 or 4 gallons per minute of the permitted retention pond effluent through the standpipe to the permitted outfall into Hyco Lake. In response, the standpipe was isolated by constructing a small earthen cofferdam across the retention pond and pumping the water from behind the dam into the remaining portion of the retention pond. At about 1:00 p.m., the leak through a small hole at a junction between metal and concrete portions of the standpipe was discovered and stopped. The repairs to the standpipe were being planned. Mr. Yates again contacted Mr. Mitchell by telephone at 2:45 p.m. to advise him of the current status. During that telephone conversation, Mr. Mitchell asked that a followup letter be sent to NCDEM when the repairs were completed. He stated that no other action by CP&L would be necessary. DEC 1 9 1994 Mr. Ken Schuster 2 Subsequent to the last telephone conversation with Mr. Mitchell, the necessary repairs to the standpipe were completed by the plant's maintenance personnel on December 13-14, 1994. The cofferdam will be removed later this week, and the retention pond system will return to its normal function. No harm to the environment or human health was observed during or following the incident. Prior to the discovery of the leak, the discharge from the retention pond was tested for toxicity on five occasions during 1994 as required by the NPDES permit. The toxicity tests performed on the pond's effluent on each of those occasions indicated no acute toxicity. Please contact Mr. Rick Yates at (919) 546-7777 if there are any questions regarding the information provided in this letter. Yours very truly, G. J.

The Instream Assessment Unit has recommended that the Company be required to report one weekly average mass based on the average weekly flow. Therefore, in addition to "Daily grab samples shall be combined into a weekly composite prior to analysis" we recommend the footnote say "The resultant concentration and the weekly average flow should be used to report the weekly average concentration of Selenium". Since only one value for the week will be required to be reported on the MR-1 form, the measurement frequency and Sample should be indicated by 2 asterisks. 2) We feel that limitations and monitoring for Units 1, 2, and 3 are sufficiently regulated at Outfall 003. Pipe 004 may be deleted. The allowance for Unit 4 to be operated in the once - through cooling mode during the winter months should be added to the effluent limitations and monitoring requirements for Pipe 003. 3) We agree that monitoring of the WWTP effluent is not necessary and the inclusion of Pipe 008 with limits and no monitoring is a good solution to provide continued proper operation of the WWTP. We would also recommend that Monthly fecal coliform monitoring and limit of 200/100ml be added to the Pipe 002 requirements since the WWTP and the sludge from the WWTP are both discharged to the ash pond. We feel that the fecal coliform limit is necessary since Hyco Lake is class B. Memorandum to Greg Nizich from RRO Re: CP&L Roxboro Draft Permit Page 2 4) The blowdown parameters limited and monitored at outfall 005 should be placed on the maintenance drain from unit 4 which discharges to the (Heated Water) discharge canal, if this is the only pipe through which blowdown occurs. Blowdown parameters should also be added to the ash pond Pipe 002 since water that would normally be blowdown is used for makeup water in the bottom ash transport system.

Steve Mitchell and Danny Smith of the Raleigh Regional Office at the subject facility on June 1, 1993. The renewal of the NPDES Permit for this facility has been held up in review by the EPA, but the permitted parameters of the previous permit are still in effect. The following comments and/or recommendations are offered: 1. Outfall 001, from the East Ash Settling Pond, and Outfall 009, from the Waste Metal Pit: These have had no measurable discharge for over a year. 2. Outfalls 002, 003, 004, 005, 006, and 007: These outfall facilities appeared well operated and maintained. 005 flows into 002, which in turn flows into 003 along with 004 and 007. 3. Pipe 008, from the Domestic Waste Water Treatment Plant (WWTP): This facility was again well operated and maintained. A review of the Discharge Monitoring Reports (DMR) for a one year period from April 1992 to March 1993 indicated no violations of permitted parameter limits. This review did find that the November 1992 DMR was incomplete due to the lack of a monthly monitoring report for the WWTP.

These projects involved the use of bottom ash from the Roxboro Plant and the project reports are enclosed. Per an agreement with Ms. Carolyn McCaskill, ash analyses outlined in III.3. and IIIA. were not required during 1992 because all of CP&L's ash use permits were in the process of being modified. The new permits will require a full TCLP analysis upon renewal, and all facilities covered by ash reuse permits will have identical monitoring requirements. Ash samples for the Asheville and Roxboro Plants were analyzed prior to the initiative to modify the permits and those analyses results are also enclosed. The TCLP results were below regulatory limits. If you have any questions or comments concerning the enclosed information, please contact Ms. Teresa Harrison at 546-4706.
