7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION ENVIRONMENTAL ASSESSMENT AND FINAL FINDING OF NO SIGNIFICANT IMPACT REGARDING PROPOSED AMENDMENT TO FACILITY OPERATING LICENSE GEORGIA POWER COMPANY OGLETHORPE POWER CORPORATION MUNICIPAL ELEGIRIC AUTHORITY OF GEORGIA CITY OF DALTON, GEORGIA DOCKET NO. 50-366 The U. S. Nuclear Regulatory Comission (the Comission) is considering the issuance of an amendment to Facility Operating License Fo, NPF-5 issued to Georgia Power Company, Oglethorpe Power Corporation, Municipal Electric
]
Authority of Georgia, and the City of Dalton, Georgia, (the licensees) for operation of the Edwin I. Hatch Nuclear Plant, Unit No. 2 (the facility) located in Appling County, Georgia.
ENVIR0NMENTAL ASSESSMENT Identification of Proposed Action: The proposed action would permit the license:.s to implement changes (called the Average Power Range Monitor / Rod Block Monitor / Technical Specification (ARTS) Improvement Program) to Hatch Plant, Units 1 and 2,.and Technical Specifications as described in their letter of February 6,1984, as supplemented April 3,1984. The following 1ssessment i
only applies to Unit 2 at this time.
The Need for the Proposed Action: The need for the proposed action is to:
1 (i) reduce the need fcr manual setpoint adjustments and allow for more direct thermal limit administration; (ii) improve the quality of electronic hardware in the Rod Block Monitor; and (iii) change certain operating limits to bring about consistency among the v'drious changes being implemented.

Environmental Impacts of the Proposed Action: The proposed action improves the accuracy of indications provided to the operator for control of thennal parameters in the reactor. The net power level is unchanged. The response of the reactor protection system under accident conditions is unchanged.
Thus, post-accident radiological releases will not be greater than previously determined, nor does the proposed change otherwise affect radiological plant effluents. Occupational exposures to radiation would also be unaffected.
Therefore, the Comission concludes that there are no significant radiological environmental impacts associated with this proposed amendment.
With regard to potential nonradiological impacts, the proposed change involves systems located within the restricted area as defined in 10 CFR 20.
No nonradiological effluents are affected, and no other environmental impact would occur. Therefore, the Commission concludes that there are no significant nonradiological environmental impacts associated with the proposed change.
Since we have concluded that there is no measurable environmental impact associated with the proposed changes to the.TSs, any alternatives tn these changes will have either no environmental impact or greater _ environmental impact. -
The principal alternative would be to deny the requested amendment.
This wot14 not reduce environmental impacts of plant operation.
Alternative Use of Resources: This action does not involve the use of resources not previously considered in connection with the Final Environmental Statements related to Hatch Unit 2 operation (Final Enviror. mental Statement dated October 1972 and NUREG-0417, dated March 1978).
7590-01 Agencies and persons Consulted: The Commission's staff reviewed the licensees' request and did not consult other agencies or persons.
FINDING OF NO SIGNIFICANT IMPACT l
The Commission has determined not to prepare an environmental impact j
l statement for the proposed license amendment.
Based upon the foregoing environmental assessment, the Commission concludes that the proposed action will not have a sionificant effect on the quality of the human environment.
For further details with respect to this action, see the application for amendment dated February 6,1984, as supplemented April 3,1984, which is available for public inspection at the Commission's Public Document Room, 1717 H Street, N.W., Washington, D.C., and at the Appling County Public Library, 301 City Hall Drive, Baxley, Georgia.
