i ANNUAL ENVIRONMENTAL OPERATING REPORT L

September.15, 1991, through September 14, 1992 1

1.

-In accordance with Environmental Technical Specification (ETS) 5.3.0, the facility design'and operational. changes were reviewed for the i

potential effect on the environment. A study of facility design and operational changes from September 15, 1991,_through" l

September ~ 14, 1992, that could have affected the environment was l

performed. Projects considered to have potential impact on the environment included:

(1) those involving excavation, construction.-

or asbestos removal; and-_(2) those resulting in new-or increased discharges to outside drains. The study identified and' documented a basis that the design and operational changes did not involve an 7

unreviewed environmental. quer, tion'.

A copy of this study is attached.

2.

In accordance with ETS 5.4.1, the following report is-specified'in-1 SQN National Pollutant Discharge Elimination System (NPDES) Permit-j No. IN0026450, and has been previously submitted-to the NRC:

-Report on results of Nonradiological Aquatic Monitoring Program -

Rotenone Studies,: submitted June 25, 1992.

DESIGN AND OPERATIONAL CHANGES BETWEEN SEPTEMBER 15,:1991, AND SEPTEMBER 14, 1992 i

FOR EFFECTS ON THE ENVIRONMENT During this report period, the facility design and operational changes and major maintenance and modification projects have-been reviewed for potential i

to affect the environment as described below.

The criteria used to identify those projects-with a potential for environmental effects included _ _(1) those I

involving excavation, construction, or asbestos removal; and-(2) those resulting in.new or increased discharges to outside drains.

1.

The following projects were reviewed and evaluated in accordance.with the i

above criteria for potential environmental impact.

p a.

Hey _I.asnea Only 10 new project packages were reviewed during.this report period.

(

All of_those projects were designed to-comply with regulatory i

permitting processes, and none of them involved any environmental impacts that were not reviewed in the original environmental impact i

statement.

b.

Special Tests

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

l c.

Temporary Alterationg 1

There were no temporary alterations made-during this period that met-the environmental impact criteria.

I 2.

Design and operational changes with a potential for causing new or increased discharges to outside drains, including runoff from excavation, were reviewed and determined to be within~the scope of the SQN National i

Pollutant Discharge Elimination System (NPDES) permit.~

i 3.

Monthly discharge monitoring reports submitted as required by the SQN i

NPDES permit were reviewed.. Permit excursions'were attributed to either-l natural causes, equipment malfunctions,-or operational _ errors'and i

determined to be within the purview of the NPDES permit 'and associated environmental evaluations.

'The cleanup of polychlorinated biphenyl discovered in the low volume waste-

-treatment pond effluent in October 1988 was_ completed.

1 1

In summary, there have been no facility design or operational changes from September 15, 1991, to September 14, 1992,_ that have resulted in an~unreviewed environmental question.
