PREFACE j l

The Annual Environmental Operating Report (AEOR) provides information and -1

- data obtained from implementation of Grand Gulf Nuclear Station's (GGNS)

Environmental Protection Plan (EPP), Appendix B to the GGNS Operating License .,

(NPF-29), which only requires terrestrial issues to be addressed, for the period January 1 through December 31, 1993. j The GGNS Final Environmental Statement did not identify any aquatic issues.

Consequently, the EPP does not address any. The GGNS National Pollutant Discharge Elimination System Permit issued by the Mississippi Department of Environmental 4

Quality (MDEQ) contains effluent. limitations and monitoring requirements for aquatic matters. The MDEQ regulates matters involving water quality and aquatic.

biota.

Tnis report addresses only those issues required by the EPP. In the past, the AEOR included activities associated with the GGNS Construction Permit,. and an Updated Final Safety Analysis Report (UFSAR) requirement which involved reporting '

regional and perched groundwater levels and preciptation data in the AEOR.

However, the Nuclear Regulatory Commission approved cancellation of Construction Permit CPPR-119 for Unit 2 on August 21, 1991 (GNRI-91/00176), and GGNS deleted-the UFSAR reporting requirement in 1993 (GNRI- 93 /00025 ) ; therefore, GGNS I

terminated reporting activities associated with these items.

2.1 TRANSMISSION LINE SURVEYS GGNS discontinued this program in 1988.

2.2 COOLING TOWER DRIFT PROGRAM GGNS discontinued this program in 1992.

2.3 ENVIRONMENTAL EVALUATIOllS The EPP permits changes in GGNS design or operation and performance of tests or experiments that affect the environment, provided they do not involve a change in the EPP or an unreviewed environmental question.

However, EPP requirements do not apply to changes, tests or experiments which T

do not affect the environment. Also, EPP requirements do not relieve GGNS of.

10 CPR 50.59 requirements, " Changes, Tests and Experiments," which address the question of safety associated with propoced changes, tests and experiments.

The EPP excludes changes, tests or experiments from the evaluation:

o If all measurable environmental effects confined to onsite areas previously disturbed during site preparation and plant construction, or o If required to achieve compliance with other federal, state or local .

requirements. t Mi\ TECH _ PUB \PROCED\SRREVFLR\AEOR.RPD-2-1

3.1- E!WIRONMENTAL' EVALUATIONS During 1993,.GGNS activities did not include any.unreviewed environmental questions. Chemistry's review of environmental evaluations indicated routine matters within the scope of expected activities. GGNS did:

I not observe any environmental consequences as a result of conduct of the activities evaluated. Appendix I contains completed evaluations for 1993.
