Dear Mr. Samworth:

Enclosed is a copy of a revised chronology of events concerning Nine Mile Point Power Plant, Unit g2.

Also enclosed is a copy of a page of the draft permit describing the conditions for discharging TDS. We are currently reviewing the ap-plicants cool'ing tower report to determine their ability to meet this requirement. Unless ambient TDS conditions are already near 200 mg/L, The applIcant should be able to meet this requirement.

There Is no condition in the permit requiring Niagara mohawk to conduct a chlorine minimization study. Tom Quinn informs me that there are no plans to certify or add this requirement at this time.

Very truly yours, A lan N. Geisendor er Assistant Sanitar gineer Energy Waste Coord nation ANG: ks cc: C. Dworkin, w/encs.
