-e 7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION LONG ISLAND LIGHTING COMPANY DOCKET NO. 50-322 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT w
The U. S. Nuclear Regulatory Commission (the Commission) 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 Long Island Lighting Company-(LILCO)thelicensee,for,operationoftheShorehamNuclearPowerStation(SNPS),
located in Suffolk County, New York.
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 September 8,1989, the licensee requested an exemption to reduce the amount of_ primary property damage insurance from 1.06 billion dollars to 337 million dollars until such time as the NRC should approve the transfer of Shoreham to the Long Island Power Authority or some other entity of New York State. 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 the Proposed Action:
The licensee's September 8, 1989 letter provided technical justification that 337 million dollars of primary property damage insurance provides an adequate level of coverage to return the SNPS plant to a condition ready for decommissioning following an accident considering the current non-operational En22gggaag8gg2 )

P condition. Granting the exemption request relieves the licensee from the i;
-unnecessary financial burden of carrying insurance coverage of 1.06 billion as L
requiredby10CFR50.54(w)(1).
Environmental Impacts of the Proposed Action:
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 staff has determined that a reduction in the amount of i
required on-site damage insurance, from 1.06 billion dollars to 337 million dollars is commensurate with the clean-up cost associated with a postulated accident while the reactor is defueled and the fuel is in the spent fuel pool.
Thus, the reduced coverage authorized by the proposed exemption is sufficient to fund clean-up of radiological impacts associated with any accident in the defueled condition.
In addition, the exemption in question would not authorize construction or operation, would not authorize a change in licensed activities nor effect changes in the permitted 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 1

environmental impacts associated with the proposed exemption..
Alternative to the Proposed Action:
Since the Comission concluded that there are no measurable environmen t
-impacts associated with the proposed exemption, any alternatives with equal or greater environmental impacts need not be evaluated.
The principal alternatives to the exemption are to require the licensee to carry 1.06 billion dollars of on-site primary property damage insurance or another amount greater than 337 million dollars. However, the NRC staff had determined that 337 million dollars is sufficient to fund clean-up of radiological impacts associated with any accident in the defueled condition.
Requiring more than 337 million dollars would impose an unnecessary financial burden and would not enhance protection of the environment.
Alternative Use of Resources:
This action does not involve the use of any resources not previously considered in the Final Environmental Statements for the Shoreham Nuclear Power Station.
l Agencies and persons Consulted:
The NRC staff reviewed the licensee's request and did not consult other L
agencies or persons.
l FINDING OF N0 SIGNIFICANT IMPACT l
The Comission has determined not to prepare an environmental impact statement for the proposed exemptien.
Based upon the foregoing environmental assessment, the staff concludes that the proposed action will not have a significant effect on the quality of the human environment.
