Dear Congressman Jones:

Thank you for your memorandum of April ll,1979 to Mr. Carlton Kammerer, Director, Office of Congressional Affairs, regarding matters raised by your constituents concerning Public Service Company of Oklahoma's pro-posed Black Fox Station. Your memorandum was referred to this office for response.

The matters raised by your constituents concern principally:

(1) the con-tinued construction and operation of nuclear power plants in light of the accident at Three Mile Island Nuclear Station, Unit 2; (2) the development of alternative methods of energy production, such as solar; and (3) oppor-tunity for public participation in the issuance of National Pollutant Dis-charge Elimination System (NPDES) Pennit OK0034614 for the proposed Black Fox Station.

In addition, you requested an updated report on the proposed Black Fox Station as well as a schedule of public hearings held or to be held.

With respect to the continued construction and operation of nuclear power plants in light of the accident at Three Mile Island, we have taken or are taking a number of actions with respect to all nuclear power plants to ensure the continued protection of the health and safety of the public.

Specifically, full-time inspectors have been assigned to each operating plant utilizing Babcock & Wilcox pressurized water reactors like those at Three Mile Island.

In addition, the licensees of all these plants which were not already shut down have voluntarily shut down their plants. We have issued confirmatory orders to the licensees of all Babcock & Wilcox reactors like those at Three Mile Island to assure that necessary plant modifications, additional training and revised operating procedures will be effected prior to resuming operation.

Licensees of all operating plants utilizing pressurized water reactors have been instructed to take specific actions with regard to the status of certain equipment, plant procedures, operator actions and facility designs. Licensees of all operating plants, including those utilizing 7 7 #7.n #5r

boiling water reactors, have been instructed to provide us with additional infomation with regard to their facilities in light of the Three Mile Island accident.

In addition, substantial effort is being expended within this agency to evaluate the factors which contributed to the Three fiile Island accident and to prevent a similar occurrence in the future.

We will carefully review all the information obtained and developed as a result of the Three Mile Island accident and take whatever further action is deemed appropriate.

With respect to alternative methods of energy production, such as solar, the Department of Energy is the Federal Agency' responsible for their re-search and development. Our consideration of alternative methods of energy production involves a comparison of the environmental impact of each nuclear power plant with other energy alternatives as part of our over-all review of each utility's application for a construction permit or an operating license under the National Environmental Policy Act. To-date, we have determined that alternative methods of energy production, such as solar, are neither technically nor economically feasible to provide the required amount of power in the time frame in which it is needed.

With respect to NPDES Permit OK0034614 for the proposed Black Fox Ctation, the Environmental Protection Agency is the Federal Agency responsi a for its issuance and for providing opportunity for public participation therein.

Our involvement with the issuance of NPDES Permits is limited to the assess-ment of the environmental impact of each nuclear power plant as part of our overall review of each utility's application for a construction pemit or an operating license.

As part of our National Environmental Policy Act review of a license application, we analyze and evaluate the potential impact of station discharges on the aquatic environment. This review is coordinated with the Environmental Protection Agency regional office or the State agency having responsibility for issuance of the NPDES Pemit.

We solicit and usually receive coments or other input from such agencies prior to issuance of our Draft Environmental Statenent. We also solicit and usually receive comments from the same agencies on the Draft Environ-mental Statement. These coments are incorporated in our Final Environ-mental Statement.

Utilities must also have a 401 Certification (under Section 401 of the Federal Water Pollution Control Act) prior to issuance of a 71 cense. Re-strictions imposed on a nuclear power plant to protect the ac"atic environ-ment from non-radiological discharges are specified in the F. 0ES Permit and the 40i Certification.

In this regard, we are precluded from adding conditions of our own by Section 511(c) of the Federal Water Pollution Con-trol Act.

In the event that the environmental statement process results in the iden-tification of potentially significant impacts due to non-radiological dis-charges, we rely on the NPDES Permit cuthority to determine apprcpriate

investigative action. However, despite the fact that another agency has primary jurisdiction for controlling non-water-borne effluents, we still consider the environmental impact'of these discharges in the overall balancing of environmentar impacts in reaching a decision of whether to issue a license.

We are enclosing a copy of the draft of NPDES Permit 3K0034614 that we have on file. This draft is interpreted as evidence that the Environmental Protection Agency considers it possible to issue such a permit for the pro-posed Black Fox Station. The actual NPDES Permit is not required until 50 days prior to any discharge covered by it, therefore, it will not be needed until the operating license stage.

With respect to the proposed Black Fox Station, 'ooth the environmental and radiological health and safety hearings have been completed. Environmental prehearing conferences were held in Tulsa, Oklahoma on July 21, 1976, January 6, 1977, February 15, 1977 and June 27, 1977.

Environmental and site suitability hearings were held in Tulsa on August 22-September 9,1977, Oct:ber 17-21, 1977 and June 5-6, 1978. Based on the record of these hearings, the presiding Atomic Safety and Licensing Board issued a Partial Initial De-cision on July 24, 1978. The Partial Initial Decision authorized the Nuclear Regulatory Comission staff to issue a Limited Work Authorization which would allow Public Service Company of Oklahoma to perform certain limited construc-tion activities for the Black Fox Station. The Limited Work Authorization was issued on July 26, 1978.

A radiological health and safety prehearing conference was held in Tulsa on June 29-30, 1978 and radiological health and safety hearings were held in Tulsa on October 10-20,1978, December 5-13, 1978 and February 19-28, 1979. While the hearings were concluded on February 28, 1979 and no fur-ther hearings are scheduled at this time, motions by the State of Oklahoma and the intervenors to stay the proceedings and to reopen the record, respectively, are under advisement by the presiding Atomic Safety and Licensing Board pending the conclusion of our evaluatioa of the safety ramifications of the Three Mile Island accident on the proposed Black Fox Station.

We trust that we have been responsive to the matters contained in your memorandum. Should you desire clarification or additional information concerning these matters, please do not hesitate to contact us.

Sincerely,

'(Signe3)T. A.Rehnf L
