September 26, 1977 letter from R.
L.
Bolger c.o Edson G. Case transmitting licensc amendment request and environmental impact appraisal
Dear Mr. Denton:
Per Reference (a), Commonwealth Edison Company requested a license mnendment to Appendix B, Environmental Technical Specifi-cations.
The proposed changes concerned measuring and reporting chemical releases and included an Environmental Impact Assessment of Discharging Boric Acid from Zion Station into Lake Michigan.
Subsequent to the submittal of Reference (a), the NRC Staff and Commonwealth Edison personnel had numerous discussions concerning the proposed changes of Reference (a).
These discussions have recently culminated in a revised set of Zion Environmental Technical Specifications for the measuring and reporting of chemical releases.
These revisions have been incorporated into the Zion Station Technical Specification format and are contained in Attachment I.
The revised changes of Attachment I have been reviewed by Commonwealth Edison On-Site and Of f-Site Review with the con-clusion that no unreviewed safety questions exist.

3.0 REPORTING REQUIREMENTS 3.1 ENVIRONMENTAL REPORTS Special reports for those programs ( Ent ra inment,
Plume and Water Quality studies) which are expected to continue for one year after Unit 1 has begun operating at full power (as determined by the Atomic Safety and License Board or appropriate appeal authority) will be submitted to the Division of Reactor Licensing within 120 days after the first year.
Based upon the results of testing o
..e thermal plume model, an analysis will be made of the possible interaction cf the plume of Unit 1 with that of Unit 2.
Annual reports for the 5 year monitoring program will also be sent to the Division of Reactor Licensing within 120 days after each successive year that Unit 1 began initial operation.
3.2 The following items will be included as an Appendix to the Annual Operating Reports.
Documentation of chemical discharges to include a,
the chemical name as used or as released, the system from which the chemical is released and the amount of chemical used or released over the reporting period.
b.
Intake and discharge temperature data.
