Box 1551 New Hill, North Carolina 27562-0165 July 31, 1996 f A&41 �EHNR Subject: NPDES Permit Issuance Permit No. NCO039586 Harris Nuclear Plant Wake County Dear Mr. Robinson: In accordance with the application for a discharge permit received on October 4, 1995 the Division is forwarding herewith the subject NPDES 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 December 6, 1983. 4` The following comments are provided in response to the May 24, .1996 comments submitted by CP&L regarding the draft permit. Although the CP&L comments were not sequentially numbered, the following responses are in corresponding order to,the comments received. General Comments The final permit pages have been sequentially numbered as requested. The Fact Sheet and Waste load Allocation were provided to Jeannie Cook during our May 13, 1996 meeting concerning the draft permit comments. Page 2 The next to last paragraph has been changed to "Any other wastewater, and stormwater associated wiih�industrial activities point source discharge to surface waters of the state is prohibited unless covered by another permit, authorization or approval." as requested. Page 4 - General Statute 143-212. defines "waters" as 'any... waterway or other body or accumulation of water, whether... public or private, or natural or artificial, that is contained in, flows `1 through, or borders upon any portion of the State...' Under this definition., the channels in question are considered waters of the state and are thereby subject to stormwater regulation. P.O.

However, during future changes to the -mits, these changes will be considered. With regard to toxicity testing, CP&L is correct in their statement that the intent of retesting is to require that the retesting be performed within 30 days if a test condition fails. However, a retest should also be conducted if te4 results indicate an invalid test. An invalid test will not be deemed as noncompliant. Any ftiilure of a toxicity test is deemed noncompliant. Any questions regarding these requirements can be discussed with Mr. Matt Matthews of my staff at (919) 733-2136.

Robinson Permit No. NCO039586 Harris Nuclear Plant Page 3 Although the mixing zone is applicable at the final discharge (outfall 006), requirements for the mixing zone are pertinent to the cooling tower component of the final discharge. Therefore, the mixing zone language is presented on the outfall 001 effluent limitation page for clarity regarding the intent of the mixing zone. Zinc and Chromium have been listed as Total Zinc and Total Chromium. Based upon a review of discharge monitoring report data, the monitoring requirements for Total Nitrogen and Total Phosphorus have been deleted for outfall 001. Because outfall 006 is the final combined outfall with discharge to a lake, and all lakes are subject to nutrient concerns, monitoring for these two parameters shall be required at the final outfall: The footnote "Test procedures shall produce minimum detection or lower reporting level of the approved procedure." has been inserted as requested. Page 9 The pH monitoring and the "no floating solids or visible foam..." footnote have been deleted as requested. In footnote (+) "Total residual chlorine" has been deleted from the first sentence, "instantaneous average" has been replaced with "daily average", and "instantaneous maximum" has been replaced with "daily maximum" as requested. The second sentence of footnote (++) has been replaced with the suggested language, "There shall be no discharge of detectable amounts of the 126 priority pollutants contained in chemicals added for cooling tower maintenance except for Total Chromium and Total Zinc.' Page 10 The Division routinely applies monthly average and daily maximum effluent limitations based upon the distinction between "municipal" and "non -municipal" in the Clean Water Act. Under 40 CFR 133, secondary treatment requires the removal of 85% of the influent BOD5 and TSS. The adoption of daily maximum limitations allows the Division to meet the requirement of being at least as stringent as the federal regulations without having to require 85% removal. In order to provide weekly average limitations in this permit, the permit would also have to require influent monitoring for BOD5 and TSS and 85% removal of influent BOD5 and TSS. The permit is being issued with daily maximum limitations. However, should CP&L wish to pursue weekly average limitations with 85% removal requirements a permit modification may be requested. The pH monitoring and the "no floating solids or visible foam..." footnote have been deleted as requested. NCAC T15A: 02B .0508 specifies Fecal Coliform and Total Residual Chlorine monitoring of domestic wastewater discharges at the frequencies provided. in the draft permit. However, ~6 -� based upon a review of discharge monitoring data for outfall 002, the monitoring frequencies for Fecal Coliform and Total Residual Chlorine have been reduced to weekly. Mr. William R. Robinson Permit No. NC0039586 Harris Nuclear Plant Page 4 The footnote "Test procedures shal�produce minimum detection or lower reporting level of the approved procedure." has been i serted as requested. NCAC T15A: 02B .0508 requires ammonia monitoring of domestic wastewater discharges at the frequencies provided in the draft permit. Based upon a review of discharge monitoring data for outfall 002, the monitoring frequency for NH3 as N has been reduced to monthly. Nitrogen and phosphorus monitoring requirements have been deleted at all internal outfalls. Because outfall 006 is the final combined outfall with discharge to a lake, and all lakes are subject to nutrient concerns, monitonng for these two parameters shall be required at the final outfall. Page 11 Oil and grease and TSS monitoring are required for metal cleaning wastes per 40 CFR 423.12(b)(5). Because any discharge from outfall 003 is routed through outfall 004, which contains equivalent limitations foroil and grease and TSS, the oil and grease and TSS monitoring at outfall 003 have been deleted. The pH monitoring and the "no floating solids or visible foam..." footnote have been deleted as requested. Based upon discussions with CP&L duration of 24 hours, it is appropria iron at daily rather than complicate tl condition of not to exceed more than no event resulting in a discharge.

Robinson Permit No. NCO039586 Harris Nuclear Plant Page 5 Paae 14 Nitrogen and phosphorus monitoring requirements have been deleted at all internal outfalls. Because outfall 006 is the final combined outfall with discharge to a lake, and all lakes are subject to nutrient concerns, monitoring for these two parameters shall be required at the final outfall. TSS monitoring at the intake has been deleted. Pages 15/16 As previously noted, all lakes are subject to nutrient concerns. The discharge at outfall 007 is to an arm of the lake which escalates the concerns over localized eutrophication. Therefore, monitoring for total nitrogen and total phosphorus shall be required. This comment was previously addressed for Page 10. The acute toxicity sample type for outfall 007 has been changed to composite. Title 15A of the North Carolina Administrative Code (T15A NCAA 2B .0508 specifies weekly Fecal Coliform monitoring for Class II treatment facilities which discharge primarily domestic wastewater. Therefore, weekly Fecal Coliform monitoring is specified for both the summer and winter effluent pages. The BODS and Ammonia limitations provided in the permit are not strictly based on maintaining compliance with DO. The BODS and NH3 as N limitations were agreed upon between CP&L and the Division as best professional judgement limitations -with Ammonia also protecting against instream toxicity. If CP&L's concern is that a violation of the Ammonia limit will automatically cause a violation in the BODS limit, then the Division may consider a CBOD5 limit in lieu of BODS. Note that the CBOD5 limit will be lower than the current BODS limit should CP&L request such a modification. The temperature monitoring requirement is specified in T15A NCAC 02B .0500 for primarily domestic wastewater discharges. The language "Test procedures shall produce minimum detection or lower reporting level of the approved procedure." has been added to both effluent monitoring pages for outfall 007 as requested Paae 17 The Division understands the concern over duplicative language. The language in question is currently part of a standard boilerplate and will be evaluated based upon this comment at such time as the boilerplate language is revised. Paae 18 The reference to Part II.E.8 has been deleted from item A.1. Mr. William R. Robinson Permit No. NCO039586 Harris Nuclear Plant Page 6 The word "regulated" has been ins( requested. between "of' and "stormwater" in item A.l.a. as As discussed in our meeting, the ir�''clusion of a site map drawn to scale is an important component of the stormwater polls, tion prevention plan and will facilitate ongoing site evaluations. A series of scale maps is certainly acceptable and CP&L has indicated that these maps are available. The stormwater outfall certification nay be signed by either a responsible corporate otticer or a duly authorized representative. Page 19 The intent of the language in item A.i.b.(1) is to be reasonable and encourage the application of best management practices in areas) where they will be reasonably beneficial. The Division expects the permittee to use sound judgement when determining what is practicable on-site and does not condone the development of exhaustive engineering studies where they are not reasonably warranted. Should CP&L identify a specific area of concern, please feel free to contact the Division for guidance. The provisions for secondary contain{nent are likewise meant to be reasonably applied using sound judgement. In response to the comment on item A.l.b.(2) and the language contained in the CP&L Mayo permit, the definition of bulk storage in Part III, Section A.3. has been changed to exclude water. Page 20 For permitting purposes, the definitio of a discharge is a point source discharge. The stormwater outfall certification ay be signed by either a responsible corporate officer or a duly authorized representative. The intent of the vehicle maintenance wording in item A:1.i. is to indicate that although the primary industrial activity (steam electric generation) may trigger coverage under the stormwater regulations there are adds tional activities, such as vehicle maintenance, that are also subject to coverage. The intent of the word "immediately" in item A.1, i. is that no delay in enacting retrieval of the information should occur when docu entation is requested. As in the CP&L Mayo permit, the wording has not been changed. The reference has been changed to �.�a). Paye 21 The analytical monitoring language in item A.2.c. has been deleted since only visual monitoring is required in this permit. Mr. William R. Robinson Permit No. NCO039586 Harris Nuclear Plant Page 7 J The first line of item A.2.f. has been changed to read "stormwater discharges associated with industrial activity" as requested. Unless specifically noted otherwise, all non-stormwater discharges identified during the application process are permitted. The discharge of wastewater from the battery room, which was identified during the draft comment period, is not considered to be permitted and should be removed. The Division recognizes that CP&L interprets "contaminated" to mean radioactive. The intent of "uncontaminated" in item A.21(2) is that there are no chemical additions to the types of non-stormwater discharges listed. Item A.21(3) has been changed to read "Discharges resulting from fire -fighting and uncontaminated discharges resulting from fire -fighting training and associated fire system testing." Uncontaminated is interpreted to mean those discharges to which no chemical additions have been made. Page 22 Representative outfall status is not applicable to visual monitoring. The intent of visually monitoring each outfall is to identify stormwater pollution problems that would otherwise go unnoticed. Spring and fall are defined, respectively, as the period from April - June and September - - November. Page 24 The intent of the Section A.3. bulk storage definition is large volumes stored in bulk that have a capacity of either 660 gallons or adjacent storage tanks with a combined capacity of 1,320 gallons. It is not intended for sources of less than 660 gallons which are scattered'across the site and have a total combined volume of 1,320 gallons to be considered bulk storage. Page 28 The 25 year - 24 hour storm event freeboard requirement in Part III.A.19. is based upon the definition of a non -discharging stormwater control system as discharging only in response to a storm event exceeding a 25 year - 24 hour storm. Page 40 The Division recognizes CP&L's concerns regarding item Part III E.9. and will take this comment into consideration when re -negotiating the Memorandum of Agreement with EPA. If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form Mr. William R. Robinson Permit No. NCO039586 Harris Nuclear Plant Page 8 of a written petition, conforming to filed with the Office of Administra Carolina 27611-7447.

The comments address items in the sequence that they appear in the draft permit and are referenced to the sequential pages of the draft permit. The Cover Sheet is considered page 1, the Supplement to P -.11 11h Lover Sheet is considered psgc r ; anj so ,`,�, h. General C9mments Page 2 CP&L recommends numbering the pages of the final permit to assist in future referencing of the document, CP&L hcreby requests spies of the Pact Sheet(s) prepared by the NCL)EM staff to provide the rationale for the limitations and monitoring requirements included in the draft permit. The next to last paragraph is inappropriate since discharges of storm water- frorn parking lots and roof tops aro not subject to regulation and are thus allowed, CP&L proposes the following language: .any other wastewater, and stormwater associated with in&atrial activities point source discharge to surface waters of the state is prohibited unless covered by another permit, authorization or approval. A revised storm water map for the facility is attached (Attachment 1) herein as an amendment to the reap originally submitted with the application for permit renewal. The revised map'indieates storm water discharges into Harris Lake, but also indicates storm water discharges into the main intake channel (SWNR-4), the emergency intako channel (SWNR- 6), and the emergency effluent channel (SWNR-7 and SWNR-8). Since storm water discharges associated with industrial activity are directly regulated only if they discharge to waters of the US or state waters, CP&L believes that the storm water discharges into those OV, MAY 10 '96 12:16PM OPERATIONS & ENVIRONMENT SUPPORT P.3 channels do not represent discharges into waters of the US or into state waters. Consequently, the discharges that are not into Harris Lake should not be.regulated. Additionally, in the preamble to the NPDES storm water application zegs.. (Vol.' SS, 11/16/90) EPA explicitly stated that transformer facilities mere not subject to the phase I storm water regulations. Consequently, CP&L requests that regulation of this stormwatcr W discharge ( SNR -9) be deferred.until it is addressed under phase 11 of the storm water program. • CP&L requests that the first paragraph be written as Follows: Thispermit may be modified, or revoked and reissued to incorporate toxicity limitations and c monitoring requirements in the eveni toxicity testing or oilier Dertlnent studies conducted on the effluent or receiving stream indicate decisively shat excursions of the water quality �� standards fob xicity may be expected in the receiving stream as a result of'this discharge. • item 2., This monitoring frequency should be reduced to quarterly since there is a large amount of data already existing on this discharge. - 15� Gtrq oaf l•C, page The second to last paragraph on both toxicity conditions, states that the permit may be reopened to include limits if data indicates potential impacts to the receiving stream. Limits are justified if there is a reasonable potential for the discharge to cause an, excursion of the water quality standards for toxicity. Limits may not be justified if there is only a "potential [adverse] impact." Additionally, this paragraph relates reopening the permit to tests performed by either CP&L or DEM. CP&L is concerned that if DEM conducts a test which indicates a potential water quality standard excursion, but CP&L splits the sample and demonstrates no potential excursion, (or vice versa), this paragraph allows the permit to be reopened to require a limit. This places CP&L iii a position of having a limit imposed based on questionable and conflicting data. CP&L requests that the paragraph be rewritten as follows: Should test data from either these monitoring requirements or tests performed by the 'elf'" IT North C'aeolina .Division o, f Environmental Management indicate decisive! that P there is a reasonable potential for water quality standarcu ds exrsions in t e I eArll � receiving stream, this permit may be re -opened and modified to include alternate J monitoring requirements or limits. The way the NOTE item is worded on both toxicity conditions, the permittee must submit suitable test results with the retest or be in noncbmpliance. However, retest conditions may 2 MAY 10 '96 12:16PM OPERATIONS & ENYIRONMEYf SUPPORT a e6 H.4 also fail due to. oircurnstances beyond the control of the permittee (e.g_, control organism survival). It is believed that the intent of this paragraph is to require retesting within 30 dans if a test condition fails, and not the way the paragraph is worded which requires the retest to be suitable. It sbould be noted that the April 3, 1996 letter to our Cape Fear facility ;from A. Preston Howard stated that CP&L's interpretation of this paragraph is correct and an invalid �A„ E -- test will not be considered noncompliant if conducted within 30 days. It is recommended that the last sentence in the paragraph be reworded as follows: Failure to retest within 30 days of initial moLijWujig gvent will constitute noncompliance with moniloring requirements. item 3., The toxicity limitation appears to be an instantaneous maximum value. This limit should be expressed so that if a test fails, the permittee may resarnple during the month and still be in compliance if the second test passes. Yids would encourage permittees to quickly identify and correct the source of toxicity in order to have the opportunity to be in compliance. If the limitation, is expressed as an instantaneous maximum the permittee has no incentive to identify and correct the problem in an expeditious manner after a failure because he will have no opportunity to remain in compliance, 5 Page 7 Pale $ Reiff. A, This item states that "the permittee may circulate heated water through the auxiliary reservoir to prevent ice'formation at any time that the surface water. temperature is below 30°F" however; if the temperature is already. below 30T, prior to the addition of heated water, ice formation has already begun. The temperature at which the permittee may begin oK circulating heated water into the auxiliary reservoir to prevent the formation of ice should be. changed to 35 °F. item 6., The Harris Reservoir is classified Class C waters in the Cape Fear River Basin as identified on the supplement page not Class C - NSW thus this item, which is a nutrient issue item, should not be included, Footnote ** CP&L requests the removal of the first sentence from the paragraph_ The first sentence implies maintaining the discharge of cooling water at the very minimum. necessay for the removal of solids even if all temperature and chlorine limitations can be met at a P66 higher rate of discharge.

Additional Information Item Information 1 Discharge Serial No. 006 is specified to maintain consistency with the outfall numbering used in the current NPDES permit. 3 Engineering drawings, Final Safety Analysis Report, system descriptions, and other related documents are available upon request. 16 Chemical constituents contained in this discharge that may be conveyed to Harris Lake will in part be representative of the naturally occurring chemical quality of the intake water and will also have chemical constitu- ents of such quality and quantity associated with similar discharges for nuclear generating facilities of this size, type, and in this geographical location. Either all or part of the elements listed in the Periodic Table, either singularly or in any combination, may from time to time be contained in the discharge. 16 Constituents checked are either 1) present in the common outfall fine as determined by conventional/priority pollutants monitoring for this permit application, 2) known to be present in the specific waste streams, or 3) used in a process which could result in discharge to waste streams. 16 Radioactive components of releases are regulated by the Nuclear Regula- tory Commission and, therefore, not addressed in this application. 16 Algicide currently used as needed is the biodispersant "ACTI-BROM 1338". Approval for use was granted June 11, 1990 by the North Carolina Division of Environmental Management. Sodium bromide in other forms may be purchased from other vendors in the future. Also, gluteraldehyde is used in closed cooling systems but it is not normally discharged; however, limited quantities may be discharged due to maintenance or system leakage. 17 The influent data requested is variable in nature and not normally under the control of the applicant. Effluent data are partially derived from Discharge Monitoring Reports previously submitted to DEM. These documents are incorporated by reference in this submittal. Other effluent data reported in this application are from Conventional/Priority Pollutants monitoring conducted at the common outfall during 1995 (Attachment 5). 17 EPA - approved procedures are used for all NPDES -- required analyses. 0111 °z a z a a 00 a C •� C,nO00g�oo as e� W _ Q N � z ' Cd U a �I O 1 � U W co C6 M A N A A Q FACT SHEET FOR WASTELOAD ALL r `� Request # 8380-8386 Facility Name: Shearon Harris Nuclear Power Plant NPDES No.: NC0039586 Type of Waste: 99.7% Industrial, 0.3% Domestic (Outfall 006 - NPP Discharge) 70% Domestic, 30% Industrial (Outfall 007 - Harris ME Center) Facility Status: Existing Permit Status: Renewal Receiving Stream: Harris Lake Stream Classification: C Subbasin: 03-06-07 County: Wake Stream Characteristic: Lake Regional Office: Raleigh Year Constructed: 1983 Requestor: Jeanette Powell Watershed W2): 70 Date of Request: 11/20/95 Surface Area (acres): 4150 Topo Quad: E23SW Avg.
