Fcnnsylvnnia i later approved :etropolitan Edison's r2 quest to discharge at the achient receiving streas te=perature when the terperature is i cbove 87*F. The cc pany is try4ng to negotiate a workable application of the 5*F rise limitation (see FES Paragraph 5.3.3) I w-ith the State. The final state 2nt should report how this preposed I variance will affect the application of ther:21 standards at i T'iP;S. " '.1s p en se : The cutcora of this negotiation has not yet bacone available. Eacause of the operation of tha 22chanical draft ecoling .f tower which raintains discharge terperature close to anbietit and because of tha large flow in the Susquehanna River which quickly dilutes the station discharge, terperature is likely to exceed achient by core than 2*F in on1'/ a very stall zone in the river. 23ragraph 5.5.2.3 of the FES reports observatices of the therral plure. There it is noted only that: " Effluent characteristics f e l 11 ' t fd

l 8>m I ; ware generally distinguishable to about 20 = (66 feet) into the river and downstream to about 50 m (164 feet) over depths up to 3 m (9.9 feet)." In war =ar ocnths the area in which temperature e::caeds anbient by ore than 2*F chould generally be centained within the above described region. 3. r. t Fa c e; Second Par wraph: " It a final supple:2nt should indicate wheth2r ther.al liaitatica imposed on Unit No. I rachanical draft cooling tower will be applied to Unit No. 2." 2asponse: It will not. ~~he N? DES Pernit is accepted as a determination that State water quality standards will be net. The FES concludes (?arcgraph 5.5.2.2) that therral impacts will be quite limited. Since this evaluation was based on the proposed operation of the nachanical draft cooling tower, any alternative operaticnal plan, especially abandonnent of the cachanical draft towers, sill be evaluated by NRC. 4.
