DOCKET NO. 50-155 ENVIRONMENTAL ASSESSMENT AND FINDING OF 1

NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory. Comission (the Comission) is considering issuance of an amendment to Facility Operating License No. DPR-6 issued to the

)

Consumers Power Company (the, licensee), for the Big Rock Point Plant, located

-in Charlevoix County, Michigan.

1 ENVIRONMENTAL ASSESSMENT l

1 i

Identification of the Proposed Action:

The proposed action would delete Section 6.4.2(d) from the Big Rock Point j

Technical Specifications. This section stated that the portable neutron or gama dose-rate measuring instruments provided for establishing permissible

~

working limits be calibrated at.least once every three months.

The proposed action is in accordance with the licensee's application for amendment dated October 24, 1988.

The~Need for the Proposed Action:

The proposed change would make the Big Rock Point Plant Technical Specifications consistent with industry practice and the Standard Technical I

Specifications. The plant has comitted to follow ANSI N323-1978 including J

the performance of a source check daily or prior to use, whichever is less l'

frequent, on each scale or decade.normally used and perform a calibration semi-annually.

Environmental Impact of the Proposed Action:

The Commission has completed its evaluation of the proposed revision to the Technical Specifications.

Performance of a more complete source check (source checking each scale or decade normally used versus source check daily or prior to use) of portable gamma and neutron dose-rate measuring instruments will better assure instrument reliability and accuracy.

The licensee feels that changing the calibration frequency from once every three months to once every six months will not result in less e curete instruments because of the more extensive source checks and because less than 5% of the instruments fail the pre-calibration checks.

The Commission concludes that there are no measurable radiological or nenradiological environmental impacts associated with the proposed aniendment.

The Notice of Consideration of Issuance of Amendment and Opportunity for Hearing in connection with this action was published in the FEDERAL REGISTER on March 29, 1989 (54 FR 12976).

No request for hearing or petition for leave to intervene was filed following this notice.

S, Alternatives to the Proposed Action:

It has been determined that there is no measurable impact associated with the proposed amendment; any alternatives to the amendment will have either no environmental impact or greater environmental impact.

The principal alternative would be to deny the requested amendment.

The proposed dose-rate measuring instrument checking changes do not involve any increase in the release of radioactive and non-radioactive effluents from the plant.

Alternative Use of Resources:

1 This action does not involve.the use of any resources'beyond the scope of

~

resources used during normal operation.

' Agencies and Persons Contacted:

The Commission's staff reviewed the licensee's request and did not consult other' agencies.or persons.

FINDING OF NO SIGNIFICANT IMPACT Based upon the foregoing environmental assessment, the Commission concluded that the proposed action will not hav'e a significant effect on the quality of the human environment.

Accordingly, the Commission has determined not to prepare an environmental impact statement for the proposed amendment.

For further details with respect to this' action, see the request for amendment dated October 24, 1988.
