ANNUAL ENVIRONMENTAL OPERATING REPORT

, SEPTEMBER 159 1995 TIIROUGII SEPTEMBER 14g 1996 ,

l I. INTRODUCTION l

The Sequoyah Nuclear Plant Annual Environmental Operating Report for the period of September 15,1995 through September 14,1996, is prepared in accordance with Environmental Technical Specification (Non-Radiological)(ETS), Appendix B,5.4.1. ETS Section 4.2. requires no special studies at this time. This report includes a summary of: j l

+ Reports previously submitted as specified in the SQN National Pollutant Discharge Elimination System (NPDES) Permit No. TN0026450.

+ All ETS noncompliances and the corrective actions taken to remedy them.

+ Changes made to applicable State and Federal permits and certifications.

+ Changes in station design that could involve a significant environmental impact or change the findings of the Final Environmental Statement (FES). ,

+ All non-routine reports submitted per ETS Section 4.1.

+ Changes in approved ETS.

II. REPORTS PREVIOUSLY SUBMITTED AS SPECIFIED IN TIIE SQN NATIONAL POLLUTANT DISCIIARGE ELIMINATION SYSTEM (NPDES)

PERMIT ,

l The following reports were submitted as specified in the SQN National Pollutant Discharge l Elimination System (NPDES) Permit No. TN0026450: l

+ Aquatic Toxicity Monitoring Study, submitted January 1996.

+ Aquatic Toxicity Monitoring Study, submitted July 1996.

III. ENVIRONMENTAL TECIINICAL SPECIFICATION NONCOMPLIANCES

+ November 1995 - Sequoyah received a Notice of Violation from the Tennessee Department of Environment and Conservation Division of Solid Waste Management (TDEC) because of ,

the failure to notify the state of a new hazardous waste stream (plotter ink) within 90 days.

The waste stream generation began in 1991. Sequoyah self reported the generation to TDEC upon discovery ofb waste stream.

+ January 1996 - The cold water return channel gate was opened without isolating the ERCW Chemical Feed. This allowed, ERCW. with a total residual chlorine content of >0.1 ppm to flow over the energy dissipater and into the intake forebay. Total residual chlorine was above limits.

+ June 1996 - NPDES Discharge Point 107, Metal Cleaning Waste Pond had a composited total suspended solids concentration of 45 mg/L which exceeded the' permit limit of 30 mg/L. The Noncompliance was the result of an algal bloom concurrently occurring with the discharge of 107. This was verified by the presence of green colored solids on filter media.

Pond inventory has been reduced to an adequate level to permit deferral of additional c releases until the winter months.

CERTIFICATIONS j

, Air permits were issued for the Emergency Diescl Generators, the Back Up Security Diesel and I the Auxiliary Boilers in August 1996. These permits were necessary to document Sequoyah's qualification as a synthetic minor cource of air pollutarus under Title V of the Clean Air Act.

Concurrence was received from the Tennessee Department of Environment and Conservation Division of Water Pollution Control to allow the use of dimethylamine and carbohydrazide in plant secondary systems.

V. CIIANCES IN FACILITY DESIGN OR OPERATION In accordance with Technical Specification (TS) 5.3.c., facility design and operational changes were reviewed for potential effect on the environment. A study of facility design and operational changes proposed from September 15,1995, through September 14,1996 was performed. Projects considered as having potential impact on the environment included: those that could have caused waste stream generation / alteration; or that required the

, acquisition / modification of permits; or involved the use of hazardous material; or required physical construction. The study identified and documented a basis that the design and operational changes did not involve an vnreviewed environmental question. A copy of this study is attached (Attachment 1).

VI. NONROUTINE REPORTS No nonroutine reports were issued during this period.

'k VII. CIIANGES IN APPROVED ENVIRONMENTAL TECIINICAL SPECIFICATION There were no changes in approved environmental technical specifications during this period.

. a. Study of Seauovah Nuclear Plant (SON)

Design and Oncrational Changes Between September 15.1995 and j September 14.1996 for Effects on the Environment Facility design and operational changes made or proposed during this report period were reviewed for potential to affect the environment as

, described below. None were found to result in an unreviewed environmental question. The following critena were used to identify those projects with a potential for environmental effects:

(1) Waste stream generation / alteration (Air, Hazardous Waste, Solid Waste, PCB's, Asbestos, Wastewater)

(2) Permit Acquisition / Modification (NPDES, Air, Inert Landfill, Other (316a,404, etc.))

(3) Hazardous Materials (4) Physical Construction Involved (Erosion / Sedimentation Effects, Transportation Effects, Noise Effects, Groundwater Effects, Surface Water Effects, Floodplain Effects, Wetland Effects, Prime Farmland Effects, Unique Natural Features Effects, Aquatic Ecology Effects, Terrestrial Ecology Effects, Protected Species Effects, Sensitive Habitat Effects, Visual Effects, Historical, Cultural and Archeological Effects, Changes in Site Land Use, and Controversy) ]

i

b. Special Tests  !

There were no special tests conducted during this period that met l environmental impact criteria.

c. Temporan* Alterations A temporary alteration was made to allow the water treatment plant sump to drain to the low volume waste treatment pond through a hose in lieu of through a corroded and leaking underground pipe. l 5
