SUPPLEMENTARY PROPOSED FINDINGS OF FACT AND CONCLU-SIONS OF LAW IN THE FOR',I OF AN INITIAL DECISION The NRC Staff, in accordance with 10 CFR 5 2.754, proposes the following revisions to "NRC Staff's Proposed Findings of Fact and Conclusion.s of Lc.w in the Form of An Initial Decision," dated August 19, 1977.
1.
On Page 18, before paragraph 24, add paragraph 23a, as follows:
48a/
Finally, the Staff has provided the Board with an evaluation of the thermal effluent limitations imposed on TMI-2 by the Common-wealth of Pennyslvania in the November 9, 1977 401 Certification.
The Staff has concluded, and the Board agrees, that operation of the facility pursuant to those limitaticns assures that the effects of the thermal discharge will not pose an unacceptable adverse impact on the aquatic ecosystem of the river.

.ne 22,1977, the Commonwealth of Pennsylvania, through its Department wironmental Resources, certified, ' pursuant to S 401(a)(1) of the Federal
- r Pollution Control Act Amendments of 1972 (FWPCA) that any disc' ge from the construction and operation of TM1-2 will comply with the appl able provisions of SS 301, 302, 306, and 307 of the FWPCA and will not violate the applicable water quality standards of the Commonwealth of Pennsylvania as approved by the United States Environmental Protection 136/
Agency On November 9,1977, the Commonwealth of Penns'f vania i
revised the 401 Certification previously issued on June 22, 1977. The 136a/
revised sections pertained to thermal effluent limitions.
The Board finds that this certification satisfies the requirement of Section 401 of the FWPCA. Pursuant to S 401(d) of the FWPCA, this Commission is required to include in an'f NRC license or permit such conditions or effluent limita-tions set forth in the 5 401 Certification. The S 401 Certification issued by the Commonwealth of Pennsylvania for this station included the following conditions and/or limitations:
