SUMMARY
OF ENVIRONMENTAL PROTECTION PROGRAM i
RESPECTING CONSTRUCTION OF GRAND GULF NUCLEAR STATION FOR SIX MONTHS ENDING APRIL 30, 1982 At the end of April, 1982, construction af Unit 1 was essentially complete.
Completion, startup, and operation of Unit #1 has been turned over to the Plant Manager. Unit 2 construction has been limited'to engineering and construction work for the purpose of protecting the investment. The following items in Unit 1 have received considerable attention since the last report: Extensive paving of streets and parking areas, receipt of nuclear fuel on site, implemented phase one of plant security system, construction on the Energy Services Center is 30% com-plete on the first two phases which include the EOF and simulator facilities.
completion of the Unit 1 Cooling Tower, and construction completed on the 100-year rainfall flood ditch. The neutron source was also received on site.
VEHICULAR MOVEMENT 2
l There was one "off limit" violation during-the reporting period. The incident involved two hunters who fired weapons at a flock of wild turkeys near the county road. The incident was reported to the proper authorities for disposition.

DUST CONTROL I
There were no obviously excessive dust control violations during the report-ing period.
SMOKE CONTROL There were no smoke control' violations during the reporting period.
4 EROSION CONTROL 4
Rain occurred on 32 separate occasions during the reporting period with an accumulated rainfall of 23.46 inches. Runoff samples were collected on 7 of these 8206010.2S/

instances and returned to the laboratory for suspended solids analysis.
Runoff was evident on 5 additional occasions, but no samples were taken because of a i
weekend or holiday. Minor erosion is still evident in several areas. Evidence of erosion continued to decline during the reporting period.
NOISE CONTROL There were no noise control violations during the reporting period.
CllEMICAL AND SOLID WASTE CONTROL Four chemical and solid waste violations were observed during the reporting period. Two oil spills were observed in Sediment Basin "B".
In both instances, the oil was quickly cleaned up by Bechtel forces. The other incidents involved a Tech-Sil spill in the plant and a turbine lube oil spill in the plant.
In both incidents, the spills were cleaned up before any contaminants could leave the plant.
4 DEWATERING Several significant changes were observed in the ground water readings during the reporting period.0W10 had an increase of almost 7 feet from its previous reading.
The following reading showed a decrease of almost 12 feet.
Evidently the initial reading was in error.
Since that time the well has been stable. OW4 showed a dry reading and then a wet reading. The wet reading was reccrded on a rising Mis-issippi River.
VECETATION The site development program was continued during the reporting period.

Fruit trees and grafted pecan trees showed excellent growth.
Bushogging of fringe areas was also completed during the reporting period. A severe winter freeze damaged domestic species much more than wild species.
A follow up investigation revealed that damage was not as severe as first thought.
1 TRANSMISSION LINES i
The semi-annual survey of the GGNS transmission lines was conducted during the reporting period. No major problem areas were identified. Preliminary clearing, l
which was began on the corridor for the yet-to-be constructed 500 Kv Ray Braswell transmission line, showed some minor erosion.
The extreme south end of the 500 Kv Franklin transmission line showed minor erosion. This is no doubt caused by ex-tremely poor soil conditions in this area.
i SEDIMENT BASINS A AND B Sediment Basins A and B continue to function properly.
Some minor siltation 2
is evident at the head of both sediment basins.
Bechtel conducted a survey to de-termine holding capacity of the basins.
This survey revealed that ample storage was availabic in the sediment basins.
Due to lack of rainfall and the increase of beavers in the general area, siltation is not the problem it once was.
