UNITED STATES NUCLEAR REGULATORY C0fHISSION DAIRYLAND POWER COOPERATIVE DOCKET NO. 50-409 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Comission (the Comission) is considering issuance of an exemption from the required on-site primary property damage insurance requirement of 10 CFR 50.54(w)(1) to the Dairyland Power Cooperative (DPC) (the licensee) for the La Crosse Boiling WaterReactor(LACBWR),locatedatthelicensee'ssiteinVernonCounty, Wisconsin.

ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:

The proposed action would grant an exemption from the requirements of

~ 10 CFR 50.54(w)(1) to reduce the full amount of required on-site primary property damage insurance. By letter dated July 26, 1985, the licensee requested an exemption to reduce the amount of primary property damage insurance from 500 million dollars to 180 million dollars. The reduction in the amount of required on-site primary property damage insurance is the proposed action being considered by the staff.

The Need for Proposed Action:

The licensee's February 7 and July 12, 1985 letters provided technical justification that 180 million dollars of primary property damage insurance provides an adequate level of coverage to return the LACBWR plant to a condition ready for decomissioning following an accident resulting in a

.: 50% fuel melt, Granting the exemption request relieves the license'e from the unneccessary financial burden of carrying insurance coverage of $500 million as required by 10 CFR 50.54(w)(1).

Environmental Impacts of Proposed Actions:

The proposed exemption affects only the amount of on-site primary property damage insurance coverage and does not affect the manner of normal facility operation or the risk of facility accidents. While the change in insurance coverage may affect the financial arrangements of the licensee and have some economic consequences, the possibility that the environmental impact of-licensed activities would be altered by changes in insurance coverage is extremely remote. The exemption in question would not authorize construction or operation, would not authorize a change in licensed activities nor effect changes in the pemitted types or amounts of radiological effluents.

Post-accident radiological releases will not differ from those determined previously, and the proposed exemption does not otherwise affect facility radiological effluents or occupational exposures. With regard to potential non-radiological impacts, the proposed exemption does not affect plant non-radiological effluents and has no other environmental impact. Therefore, the Commission concludes there are no measurable radiological or non-radiological environmental impacts associated with the proposed exemption.

Alternatives to the Proposed Action:

Since the Comission has concluded there is no measurable

environmental impact associated with the proposed exemption, any alternatives with equal or greater environmental impacts need not be evaluated. The principal alternative to the exemption would be to require

Alternative Use of Resources:

This action does not involve the use of resources not considered previously in the Final Environmental Statement for the La Crosse Boiling Water Reactor.

Agencies and Persons Consulted:

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

FINDING OF NO SIGNIFICANT IMPACT The Commission has determined not to prepare an environmental impact statement for the proposed exemption.

Based upon the environmental assessment, the NRC staff concludes that the proposed action will not have a significant effect on the quality of the human environment.

For further details with respect to this proposed action, see the licensee's letters dated February 7, July 12, and July 26, 1985. These letters are available for public inspection at the Commission's Public Document Room, 1717 H Street, N.W., Washington, D.C., and at the La Crosse Public Library, 800 Main Street, La Crosse, Wisconsin 54601.
