r.. [I DOCKET NO. 50-493 ENVIROM;EhlAL ASSES? PENT AND FINDING OF N0 SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of an exemption from the requirements of footnote d-2(c) of Appendix A to 10 CFR Part 20 to the Union Electric Company (the licensee) for the Callaway Plant located at the licensee's site in Callaway County, Missouri.
ENVIR0t;t' ENTAL ASSESSMENT Identification of Prcresed Action: The exemption would relax the requirement in Footnote d-2(c) of Appendix A to 10 CFR 20 which states, "No allowance is to be made for the'use of sorbents against radioactive gases or vapor." The exemption would allow the use of a radiciodine protection factor of 50 for cer-tain respiratory protection canisters used by workers at the licensee's Callaway Plant. The staff's technical evaluation of this request will be published in a report entitled " Safety Evaluation Report Related to the Use of Radiciodine Protection Factor for Sorbent Canisters at Callaway."
The exemption would be responsive to the licensee's application for exemption dated October 22, 1985, supplemented by letter dated August 29, 1986.

. The f eed for the Prcoosed Action: The proposed exemption is needed because tI c 'cature. deteribed ir; ti.e litmh 's r eg.es L are cotatiai reu rz *r u -
duce occupational exposure to radiation for some tasks at the Callaway facility.
Environmental Impacts of the Proposed Action:
The preposed exemption >;ill most likely reduce the work effort and occupational exposure for some tash at the Callaway Plant. As stated in the staff's Safety Evaluation Report:
The utilization of air purifying respirators in lieu of air-surplied or self-contained apparatuses, where possible, can result in person-rem reductions estimated overall at 30% for tasks requiring radiciodine _
protection, and up to 50% for several major tasks. The light weight, less cumbersome air purifying respirators (i.e., sorbent canisters) can provide increased comfort and mobility in most cases, and result in increased worker efficiency and decreased time on-the-job. The licensee has orovided a task analysis which shotts that the use of sorbent canisters at Callaway Plant can result in significant dose savings and shculd be an effective ALARA measure.
With regard to potential radiolecical impacts to the general public, the pro-posed exemption involves features located entirely within the restricted area as defined in 10 CFR Part 20.
It does not affect the potential for or con-sequences of radiological accidents and does not affect radiclogical plant effluents. The exemotion has no effect on non-radiological impacts of facility operation. Therefore, the Commission concludes that there are no significant environmental impacts associated with the proposed execption.
Alternative to the Proposed Action: Since we have concluded that the envircr-mental effects of the preposed action are negligible, any alternatives with equal or greater environmental impacts need net be evaluated.
The principal alternative wculd be to deny the requested exemption. This would not reduce environmental impacts of plant operation and would result in reduced operational flexibility.

- Alternative Use of Resources
- This action involves no use of resources not previously considered in the Final Environmental Staternents (construction per-mit and operating license) for the Callaway Plant.
Agencies ard Persons Consulted: The NRC Staff reviewed the licensee's request and consulted with an NRC contractor at Los Alamos National Laboratory.
FINDING OF NO SIGNIFICANT IMPACT The Cvimission has determined not to prepare an environmental impact staterent for the proposed exemption.
Based upon the environmental assessnient, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
For details with respect to this action, see the request for exemption dated October 22, 1985 and supplemented August 29, 1986, which is available for public inspection at the Connission's Public Docurrent Room,1717 H Street, N.
F., Washington, D. C., and at the Fulton City Library, 709 Market Street, Fulton, Missouri 65251 and the Olin Library of Washington University, Skinker and Lindell Boulevards, St. Louis, Missouri 63130 Dated at Bethesda, Paryland, this day of 1986.
