TVA is required by its National Pollutant Discharge Elimination System (NPDES) Permit for Sequoyah Nuclear Plant (SQN) to conduct and report annually on operational nonradiological monitoring to evaluate potential effects of SQN on Chickamauga Reservoir. Because few changes were identified through 1984, the following changes were recommended in June 1985: (1) terminate studies on benthic macroinvertebrates, mollusk bioaccumulation, fish impingement, fish gill netting, fish creel surveys, and water quality at the plant intake and discharge; (2) continue studies on plankton and larval fish with specific changes; and (3) continue cove rotenone studies without change. These recommendations were instituted in July 1985 following approval from the Environmental Protection Agency (EPA). This report evaluates 1985 results for the continued portions and, briefly, for the discontinued portions conducted prior to EPA's approval. Evaluation of water quality data showed that during low flows SQN altered the distribution of DO in the water column at and downstream of the diffusers. Studies to define the extent and duration of the DO alteration will be conducted during spring and summer when SQN resumes operation.
