D0CKET NO. 50-416 NOTICEOF_ ENVIRONMENTAL _AS_SESSMENTANDFINDINGOFNOSIGNIFICANTIRA,CT 1
The U.S. Nuclear Regulatory C, omission (the Commission) is considering
, issuance of an exemption fron, the requirements o.f 10 CFR Part 20, Appendix A, footnote d-2(c) to Mississippi Power and Light Company, et al. (the licensee),
j for the Grand Gulf Nuclear Station, Unit No.1, (the facility) located in Claiborne County, Mississippi.
ENVIRONMENT,AL ASSESSMENT Identification of Proposed Action:
Footnote d-2fc) of Appendix A to 10 CFR 20 states, "No allowance is to be made for use of sorbents against radioactive gases or vapor." The proposed exemption would allow the use of a radiciodine protection factor of 50 when j
i using the mine safety appliances (MSA) GMR-1 canisters at the facility. The proposed exemption is in response to the licensee's application dated June 29, 1987, as supplemented August 21, 1987.
The Need for:the Proposed __ Action 1 The proposed exemption is needed to facilitate certain operations at the
]
facility in areas where airborne radiciodine levels necessitate respiratory protection for workers. The requested exemption would allow utilization of i
air-purifying respirators in lieu of supplied-air or self-contained apparatuses.

P
7 A supplied-air respirator can limit a worker's efficiency because ths worker is restricted to the area within the reach of his air-supply hose. A self-contained breathing apparatus is usually very heavy and cumbersome, and has a limited air supply. Therefore, a person using this type of apparatus is. less mobile and less efficient in performing his duties. Air-purifying respirators, on the other hand, are lightweight, and their use' would reduce the worker's physical work effort and time spent in the work area, and thereby result in less personnel radiation exposure'!
Environme,n,1,al,J,mpa,c,t_s of the Proposed Action:
The proposed exemption involves a change in the installation or use of the facility's components located entirely within the restricted area as defined in 10 CFR Part 20. The staff has determined that the proposed exemption will re-sult in a small increase in the amount of low-level solid waste due to the dis-pesal of used sorbent canisters.
However, the proposed exemption involves no significant increase in the amounts, and no significant change-in the types,
, of any effluents that may be released offsite.
Because the.use of air-purifying respirators will allow the plant workers to perform their jobs more efficiently than could be done using supplied-air or self-cortained apparatuses.this exemption will most likely reduce the individual or cumulative occupational radiation exposures at the Grand Gulf Nuclear Station by decreasing worker time spent in radiation areas. The exemption does not affect non-radiological. plant effluents and has no other environmental impact. Therefore, the Commission.
concludes that there are no significant environmental-impacts associated with
'the proposed exemption.
.{
i k l Alternative to the Pr,opo_s,ed Action:
Since we have concluded there are ne significant environmental impacts for
]
the proposed action, any alternatives with equal or greater environmental impacts need nct be evaluater'.
1 The principal alternative would be to deny the requested exemption.
Such an action would not reduce environmental impacts of plant operation.
I Alternative Use of Resources:
This action involves no use of resources not previously considered in the Final Environmental Statement for the Grand Gulf Nuclear Station, Unit 1, i
dated September 1981.
l l
genciesandPersonsConsulted:
i The NRC staff reviewed the licensee's request and did not consult with ary' s
i other agencies or persons, j
i FINDING OF NO SIGNIFICANT IMPACT J
The Commission has determined not to prepare an environmental impact statement for the proposed exemption.
Based upon the foregoing environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
For further details with respect to this action, see the application for exemp-4 tion dated June 29, 1987, as supplemented August 21, 1987, which are available t
