ENVIRONMENTAL TECHNICAL SPECIFICATION MEETING llELD BY EP WITH DUKE POWER COMPANY ON 11/15/72 The purpose of the subject meeting was to discuss Duke comments on the draft Environmental Technical Specification proposed by EP.
People who attended are listed in an attachment to this note along with the draf t Appendix B (ETS) and a specification outline used at the meeting.
Problems involving plant operating parameters and discharges appear to be resolved. Agreement was reached on maximum temperature, AT and rate of temperature change although some questions remain regarding just exactly how Duke will operate the plant to control AT.
This i
apparently is a trade off between constant AT at as low as practicable and the rate at which cool water in the lake is used up during some months of the year.
Maximum temperature from condenser discharge will be 100 F (averaged for three units), maximum AT will be 30 F and maximum rate of decrease will be 6 F/ hour in the winter and 10 F/ hour in the spring and fall.
Duke raised the question as to what constitutes chemical discharge and questioned the requirement of coordinating chemical discharges with the hydro operation. Chemical discharge is being interpreted as just what the plant adds to the environment and it was decided that there would be no requirement to coordinate chemical discharges with the hydro operation. Ilowever, spec should include pil limits (between 6 - 8.5) and the yearly quantities and maximum concentrations of release.
i Duke should include a statement that it does not plan to use chlorine.
All chemical releases will be by way of a 8 million gallon settling l
pond having a continuous discharge into the Keowee River.
On the matter of drawdown of the lake, Duke has a tech spec limit of i
no further than 775 feet elevation but also has an agreement with the Corporation of Engineerb that it will draw down to 775 feet in the event of a draught.
The problems involving environmental surveillance were not resolved easily or totally. Part of the trouble lies in the fact that Keowee is such a new lake that baseline data does not exist. Duke would like to take full advantage of the Department of Interior Studies now going on but it is not clear how Duke will work up its program around j
the Interior's program and what will happen if Interior pulls out.
Duke also feels that non generic studies are too taxing on manpower when lots of plants come on the line and therefore, the effort sh ;1d be to perform generic studies in a fairly homogeneous region and
.(
devote.the rest of the effort to special problem area research. EP dues not feel that we are at the point where we can say that Lake Norman i

O NOV 21 572 This matter is still unresolved.
is the same as Lake Keowee.
Duke will use vegitation as an index of impact rather than animals because it is easier, cheaper and involves less manpower and in the long run avoids an impact on wild life worse than the nain reason for the study.
Duke will redraf t the Environmental Technical Specification and resubmit it for EP review in the near future.
It was also stated by Duke that it made application for its State Water Quality Certificate June 23, 1971 but has not received it.
This is a prerequisite to licensing.
