ENVIRONMENTAL IMPACT APPRAISAL BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 62 TO FACILITY OPERATING LICENSE NO. NPF-1 PORTLAND GENERAL ELECTRIC COMPANY THE CITY OF EUGENE, OREGON PACIFIC POWER AND LIGHT COMPANY TROJAN NUCLEAR PLANT DOCKET NO. 50-344 Proposed Action This Environmental Impact Appraisal addresses two proposed changes by licensee Portland General Electric Company, et al. The proposed changes to the Environmental Technical SpecificationE Xiipendix B to Facility Operating License No. NPF-1 are:
1.
the discontinuation and cancellation of the cooling tower plume study, and 2.
the deletion of most of the existing terrestrial monitoring programs, and a modification to the aerial photographic monitoring program.
Discussion and Assessment 1.
The Cooling Tower Plume Study.
l l
By letter dated October 23, 1979, Portland General Electric Company initiated the discontinuation of the Cooling Tower Plume Monitoring Program, in accor-dance with the Environmental Technical Specifications (ETS) 4.3.1.3 and 5.5.1.c.
Section 4.3.1.3 of the ETS requires a topical summary report providing evaluation of the progran to be submitted two years after the initiation of full power operation. The topical summary report has been submitted by Portland General Electric in fulfillment of that requirement.
The report concludes that the cooling tower plume program can be tenninated j
due to the finding that no adverse impacts have been reported by the program.
l Our review of the submitted topical report indicates that the report satisfies l
tha requirements of Section 4.3.1.3 of Trojan ETS. Our analysis of the data presented in the report leads us to conclude that the monitoring program should be tenninated because no adverse impacts have been observed and the cooling tower plume characteristics have been adequately recorded as required.

Terrestrial Monitoring Program Changes.
We have reviewed the annual reports for the results of the environmental monitoring program and also the files associated with the Trojan Nuclear Plant and the licensee's request of January 13, 1981 to delete certain terrestrial monitoring programs.
Trojan was expected to have a minimal effect on the terrestrial environment.
This was confirmed by the monitoring program. No adverse terrestrial impacts could be attributable to Trojan operation, and construction impacts were transi tory. The operating license was issued in 1975 with a provision which included a drift monitoring program to detect possible terrestrial impacts due to increase in salts concentration. Af ter several years of monitoring, it became apparent that no observable impacts were occurring and a portion of the program was deleted as a condition of the license. However, the licensee has contir.ued to carry out photography in the Trojan area.
The photographic monitoring consists of black and white, color and infra-red photographs taken semi-annually to assist in evaluation of the vegetation.
Because of the lack of observed impacts, the requirements can be reduced such that infrs-red photographs taken every two years is all that is required.
The accompanying Environmental Protection Plan provides for such a reduced program.
Other portions of the overall monitoring program included observations and/or trapping of birds, large and small mammals, reptiles and amphibians. Deter-minations of herbicide concentrations-were.also made. These portions of the program also 1 dicated a lack of identifiable impacts and the requirements should be deleted.
Conclusion On the basis of the foregoing, we conclude that the proposed changes are acceptable and will not significantly affect the quality of the human environment.
We have reviewed the proposed changes relative to the requirements set forth in 10 CFR Part 51 and the Council on Environmental Quality's Guidelines, 40 CFR 1500.6. We have detennine1 that the proposed l
license amendment will not significantly affet.t the quality of the human environment. Therefore, the staff has found that an environmental impact statement need not be prepared, and that pursuant to 10 CFR 51.5(c), the issuance of a negative declaration to this effect is l
appropriate.
