TENNESSEE VALLEY AUTHORITY KNCXVILLE. TENNESSEE 37902 APH I O 1989 Mr. Philip L. Stewart, Manager Chattanooga Field Office Division of Water Pollution Control 2501 Milne Avenue Chattanooga, Tennessee 37406-3399
Dear Mr. Stewart:
SEQUOYAH NUCLEAR PLANT (SQN) - FOLLOWUP TO PERFORMANCE AUDIT INSPECTION (PAI) CONDUCTED PARCH 29-31 During the PAI conducted at SQN on March 29-31, Ann McGregor indicated that the additional monitoring data required by Part III F. of the National Pollutant Discharge Elimination System (NPDES) permit had not been submitted for 1987. She requested that we provide this data to avoid a Notice of Violation.
A review of our files regarding these data, conducted af ter the PAI, indicates that these data were no longer required by the NPDES permit af ter July 1985. The report " Aquatic Environmental Conditions in Chickamauga Reservoir During Operation of Sequoyah Nuclear Plant (SQN) -
Fourth Annual Report (1984)" submitted June 25, 1985, recommended that the water quality monitoring (both monthly plant intake / discharge sampling and quarterly reservoir sampling) be discontinued unless changes in plant operation suggest that some alteration of Chickamauga Reservoir water quality may occur. A copy of the transmittal letter and selected pages from the report are enclosed (Enclosure 1).
In a July 15, 1985 letter (Enclosure 2) to the Tennessee Valley Authority, the Environmental Protection Agency concurred with the report's recommendations. Water quality data on the plant intake / discharge were reported for the last time in the fif th annual operational aquatic monitoring report submitted August 29, 1986.
This monitoring was discontinued af ter 1985 because there have been no changes in plant operations that suggest some alteration of Chickamauga Reservoir water quality.
If you or your staff have any questions or comments regarding this matter, please contact Abraham H. Loudermilk, Jr. at (615) 632-6656 in Knoxville.
Sincerely, W

Dear Mr. Barrett:
Enclosed are two copies of the report " Aquatic Environmental Conditions in Chickamauga Reservoir During Operation of Sequoyah Nuclear Plant (SQN) - Fourth Annual Report (1984)." This report is submitted in accordance with part I.,
section B.I.c., and part III., section F.,
of the Sequoyah National Pollutant Discharge Elimination System Permit.
Section F requires this monitoring program to "...
continue until at least June 1, 1984 (two years after commercial operation of unit 2)
The enclosed report summarizes data collected January through December 1984. We consider this the final comprehensive monitoring report for SQN because the program has surpassed the date required by the permit. As such, the report provides reconsnendations for future direction (continue, terminate, or redesir,n) of each type of aquatic monitoring. We plan to provide a report in 1986 presenting results of the continued / redesigned studies plus other data collected in 1985.
We ask your expeditious concurrence with our recommendations because we would like to initiate our recommendations as soon as possible.
If you have any questions, please call Clyde W. Voigtlander at FIS 856-6655 or (615) 632-6655 in Knoxville, Tennessee.
Sincerely.

6.0 CONCLUSION
S AND RECOMMENDATIONS This report presents results of sample collections in 1984, compares those results with other operational and preoperational results,
.I and provides recommendations for each type of study conducted as part of
{
the monitoring program. Evaluations and subsequent recommendations should be made unless studies were conducted under " normal" plant operational conditions. The long-term (1985-1990) generation level for SQN is pro-jected to be approximately 70 percent of the maximum possible on an annual basis. Generation levels experienced during the five years this monitoring program has been conducted were 1980--3 percent; 1981--24 percent; 1982--51 percent; 1983--68 percent; and 1984--63 percent. Operational loads were low during 1980, 1981, and 1982 because of plant startup and testing. Loads during 1983 and 1984 were near the level expected in the future and should be representative of " normal" plant operating conditions.
Numerous differences among stations and/or years were apparent from these monitoring results. Important observations and differences are presented below along with conclusions regarding their relationship to SQN operations and recommendations for each type of study conducted as part of this monitoring program.
1.
Water quality monitoring included both monthly plant intake / discharge sampling and quarterly reservoir sampling. Discharge water quality was comparable to that of the intake during sample periods in 1984 as well as during previous operational monitoring periods suggesting operation of SQN had little effect on the chemical co.nposition of water withdrawn and discharged back to Chickamauga Reservoir.
l
-361-L________________.
9 Likewise, data from reservoir stations upstream and downstream of SQN indicate no adverse alteration of water quality in Chickamauga Reservoir due to operation of SQN. Therefore, it is recommended, except for instream water quality parameters collected in onjunction with plankton sampling, that water quality monitoring be discontinued unless changes in plant operation suggest some alteration of Chickamauga Reservoir water quality may occur.
t 2.
Spatial differences (among stations) occurred during several sample periods for both phytoplankton and zooplankton. Most differences were considered inconsequential because they were slight or the type which were not induced by plant operations (e.g., increases in phyto-plankton densities at a station only a few hundred yards downr.tream of the diffusers). However, differences which occurred during the spring sample periods of 1982 and 1983 were substantial. Design of the monitoring prograta did not allow separation of the relative contribu-tion of SQN operations from other physical f actors in causing these changes. Operational monitoring data collected to date indicate SQN has had little influence on phytoplankton and zooplankton during I
i winter, summer, and fall.
l 1
Temporal differences (i.e., among preoperational and operational periods) have also occurred. Preoperational data indicate a pro-l gressive trend toward greater plankton productivity which continued into the first year of operational monitoring (1981). Conditions during the second, third, and fourth years of operational monitoring (1982, 1983, and 1984) were similar to those which existed during the
