SUMMARY
OF ENVIRONMENTAL PROTECTION PROGRAM RESPECTING CONSTRUCTION OF GRAND CULF NUCLEAR STATION (GGNS)
FOR SIX MONTHS ENDING APRIL 30, 1983 Construction of Unit 1 is 100% complete and startup is imminent.
Unit 2 is 32% complete with work limited to engineering and construction primarily for the purpose of protecting the investment.
Construction emphasis was placed on the following area during the reporting period:
o In the control building, cable tray and conduit were installed on all elevations and modifications to Power Generation Control Console (PGCC) panels continued.
o In the containment building, concrete placement continued in the drywell, along with piping work in the steam tunnel area.
In the auxiliary building, emphasis was placed on HVAC duct, o
cable tray, and piping installation.
In the turbine building, components of the Seal Steam System o
and several miscellaneous pumps were set.
Welding of the main condensers and placement of concrete for the internal walls below Elevation 133 continued.
o The security barrier between Unit 1 & Unit 2 was moved from the wall at column line 20 to the wall at column line 17, Elevation 166.
The Energy Services Center (ESC) is 75% complete, with site work nearing completion. Final grades have been established for the 10-acre site, with approximately four acres seeded. Some reseeding will be necessary because of repeated heavy rainfalls. All parking lots and some roads have been paved.
Several portions of the ESC are now occupied by support groups.
The GGNS Environmental Staff was reorganized during the reporting period to place it under the direction of the Nuclear Services Department. The Environmental Protection Program is being implemented by Nuclear Services Administrative Procedures, supplemented by existing Plant Staff procedures.
Vehicular Movement There were no "off limit" violations during the reporting period.
Attachm:nt to AECM-83/2-0005 Page 2 Dust Control There were no dust control violations during the reporting period.
Smoke Control There were four smoke control violations during the reporting period. All involved excessive emissions from the burn pit.
A program has been developed to closely monitor burn pit operations and emissions. This has resulted in a reduction of smoke control violations.
Erosion Control Rainfall occurred on 33 separate occasions during the reporting period, with an accumulated rainfall of 51.68 inches. Runoff samples were collected on 18 of these instances and returned to the laboratory for suspended solids analysis. Runoff was evident on three additional occasions, but no samples were taken because they occurred on a weekend or holiday.
Noise Control There were no noise control violations during the reporting period.
Chemical and Solid Waste Control Two chemical and solid waste violations were observed during the reporting period. A minor Betz chemical spill occurred; however, no environmental damage resulted. Additionally, a small sheen of oil was observed at the head of Sediment Basin "B" following a heavy rainfall. The oil was contained by n boom and a survey the following day revealed no oil present.
No cleanup effort was necessary.
Regional Groundwater Dewatering The 12 regional groundwater wells and 14 perched aquifer wells were read during the reporting period.
Several significant changes were observed in the regional groundwater readings during the reporting period. Several wells were not read because they were inundated by a high Mississippi River level which caused severe backwater flooding.
l The perched aquifer wells were read once each month during the reporting period, with dewatering well DW-8 recording four i
readings above 109.0 ft. Mean Sea Level (M.S.L.).
Readings above 109.0 ft. M.S.L. are noted because they are above the design maximum groundwater levels for GGNS. When this 1

condition exists, the dewatering wells activate and pump until the water level drops below 109.0 ft. M.S.L.
Several of the dewatering wells are inoperable and measures are being taken to have these wells repaired.
Vegetation The Site Development Program continued during the reporting period. The winter food plots experienced. limited success because of high backwater flooding during the winter months.
Fruit and nut trees were pruned during the reporting period.
In addition, the MP&L garden plot and hay field were disced to

provide a good seed bed.
No problem areas were observed during the reporting period.
Transmission Lines No transmission line surveys were conducted during the reporting period.
Sediment Basins A & B' Moderate siltation continues to build up in the upper end of j
Sediment Basin "B".
The sources of the silt are areas of the j
construction site which have not been revegetated and the heavy raiafall experienced during the reporting period, i
