,. All water supplies Gamma isotopic analysis will be performed on all water samples regardless of gross beta activity to simplify analysis requirements and for analysis completeness.

6.1.5.2 Sample Collection Sampling locations, frequencies, and analyses for the different types of environmental samples are discussed below in general.

More specific information for each sampling parameter is given in Table 6.1.30.

6.1.5.2.1 Direct Radiation A gamma radiation survey will be made in the immediate vicinity of the site before plant operation. TLD badges will be used to document long-term integrated dose rates. These measurements will be made quarterly at the Grand Gulf Military Park, Port Gibson, on the site perimeter, at distances 5 to 10 miles, and 10 to 20 miles northeast of the site. Each dose measurement will be based on readings of at least two thermo-luminescent dosimeters.

The exact locations of TLD stations are based on meterological data and the gamma radiation survey. A comparison of perimeter and more distant TLD stations will provide a basis for distinguishing changes due to plant operation from changes due to other causes.

6.1.5.2.2 Airborne Particulate As a part of the atmospheric neasurements program, air sampling stations will be established in each quadrant at the site perimeter, at the residence having the highest X/Q value, at Grand Gulf Military Park, and in the town of Port Gibson (Figure 6.1-6). The site perimeter and the residence having the highest X/Q value represent the areas of highest potential concentrations. Grand Gulf Military Park and Port Gibson rcoresent potential population exposure areas. Exact locations of the samples were based on ensite meterological data. In addition, two background air sampling stations will be established as a control at a distance of 10 to 20 miles northeast of the site (Figure 6.1-6). Airborne particulate material will be collected continuously on high efficiency filters. Filters will be changed weekly to avoid excessive dust loading and a beta count taken after a 48-hour decay period to permit decay of naturally occurring Radon and Thoron daughter products. Once each quarter, a gamma isotopic analysis will be performed on a composite sample of the filters.

6.1-27

GG ER 6.1.5.2.3 Airborne Padioiodine For the first 6 months and the final 6 months of tha preoperational environmental radiological monitoring program, each air sampling station will be equipped with charcoal cartridges for the collection of iodine. These cartridges will be removed and analyzed weekly for Iodine-131. This frequency was selected to avoid decay of the Iodine-131 prior to analysis.

6.1.5.2.4 Surface and Drinking Water Mississippi River water will be sampled monthly upstream between the mouth of the Big Black River and the plant outfall and downstream between the plant outfall and the St. Joseph Ferry.

These samples will have a gamma isotopic analysis performed monthly. Tritium analysis will be performed quarterly on a composite from each sampling location. Drinking water from sources most likely to be affected by plant operations (cisterns near the plant) will be collected and analyzed monthly.

Iodine-131 and gamma isotopic analyses will be performed. In addition, a quarterly composite will be analyzed for Tritium.

One well near the site and wells at Grand Gulf Military Park and Port Gibson will be sampled and analyzed quarterly. Gamma isotopic and tritium analyses will be performed on these samples of untreated well water.

6.1.5.2.5 Milk Milking animals are not normally present in the site environs.

However, should one or more be introduced, samples will be taken from the animal in the higher D/Q sector. Samples will also be taken from milking animals in areas if the dose, due to e f fluents , is calculated to be greater than 1 mrem /hr (maximum of three samples; if more than three areas are involved, the worst three cases will be selected). A control sample will be collected from the dairy herd at the Alcorn State University.

Iodine-131 and gamma isotopic analyses will be performed on each sample.

6.1.5.2.6 Fish and Invertebrates 2 Important sport and commercial fish will be sampled semiannually in the plant discharge outfall area (Hamilton Lake may be sampled if it is not feasible to obtain a sample from the Mississippi River). Specimens collected wiJ.1 have a gamma isotopic analysis performed on the edible portions.

6.1.5.2.7 Beef (or Goat) Meat Samples of beef (or goat) will be obtained semiannually from farms within 10 miles of the site which may be affected by plant discharges. If such samples prove to be unavailable, feed stuff and forage will be substituted. A background sample will be 6.1-28 Amend. 2 11/79 1458 326

GG ER taken from farms, preferably 10 to 20 miles northeast of the site. Gamma isotopic analysis will be performed on edible 2 portions of samples.

6.1.5.2.8 Deer Meat Deer will be sampled annually in the general vicinity of the site in areas where hunting is permitted. Gamma isotopic analysis will be performed on edible portions of each sample upon collection.

6.1.5.2.9 Fruits and Vegetables Vegetables will be sampled at time of harvest except for green leafy vegetables, which will be sampled monthly when available.

Samples will be collected from the garden nearest the point of greatest D/Q value. Commercial and private fruit production is 2 rare in the site vicinity. Wild fruit is present, however. Wild fruit will be collected, as available, from the site environs, preferably from high D/Q sectors. Fruit and vegetable background samples will be obtained from an area preferably 10 to 20 miles northeast of the site. Gamma isotopic analysis will se performed on each sample upon collection.

6.1.5.2.10 Sediment Shoreline sediment will be sampled semiannually downstream of the plant outfall. The amount of silt in and the flow of the 1 Mississippi River render midstream sediment sampling impractical.

Gamma isotopic analysis will be performed on each sample.

6.1.5.2.11 Soil One set of soil samples wi'l be taken prior to plant operation.

Samples will be collected at each air sampling location. Gamma isotopic and Sr-90 analyses will be performed on each sample.

6.1.5.3 Data Analysis and Presentation A report will be prepared to present and evaluate preoperational environmental radiological monitoring results. Data obtained from the preoperational monitoring program will be used along with meterological data to reestimate the possible dose to man from plant operations. Suitability of sampling media, locations, and frequency will be reevaluated prior to plant operation.

Changes to the program may be made as indicated by this reevaluation and applicable guides.

6.1.5.3.1 Direct Radiation Gamma radiation survey results will be reported in pR/hr. Direct radiation TLD badge results will be reported as a quarterly integrated dose in mR along with the average and standard 1458 327 6.1-29 Amend. 2 11/79

GG ER deviation for all readings. Quarterly doses at indicator staticns will be compared with quarterly doses at background (control) stations.

6.1.5.3.2 Airborne Particulate All results will be reported in pCi/m 3. A statistical evaluation will be made of station-to-station and week-to-week variations in gross beta results. These variations will be evaluated in terms of seasonal fluctuations, influences of worldwide fallout, and other sources. Gamma 1sotopic analysis data will be used to identify any radionuclides that may be attributed to reactor operation.

6.1.5.3.3 Airborne Iodine All results will be reported in pCi/1. If iodine-131 is detected on the charcoal cartridges, the source of the iodine-131 will be evaluated.

6.1.5.3.4 Water All results will be reported in pCi/1.

6.1.5 3.5 Milk Results will be reported in pCi/1. Indicator stations, if available, will be compared to data from the dairy herd at Alcorn 2lf State University.

6.1.5.3.6 Fish and Invertebrates Results will be reported in pCi/kg wet weight.

b.1.5.3.7 Beef (or Goat), Deer Results will be reported in pCi/kg wet weight. Radionuclides

• which could be identified with plant operation will be evaluated in terms of the dose to man.

6.1.5.3.8 Sediment and Soil Results will be reported in pCi/kg dry weight and will only be used as indicators of buildup of radioactivity in the environment.

6.1.6 Supplementary Programs 6.1.6.1 Baxter Wilson Impingement Study Systematic sampling of organisms impinged on the traveling screens of the condenser cooling water intake structures of both Units 1 and 2 at MP&L's Baxter Wilson Steam Electric Station was 6.1-30 Amend. 2 11/79 1458 328

GG ER conducted from March 1973 through February 1974. Samples from operating units were generally collected on a daily basis from March 12 through May 11. Subsequently, samples were collected 2 days per week.

Detailed descriptions of the intake structures and sampling and laboratory analyses methods are presented in the Environmental Field Measurements Programs, Interim Report 2, Section 3.6.

Results of the sampling program are presented in the Environmental Field Measurements Programs, Supplementary Report.

6.1.6.2 Environmental Photography One series of late summer overflights using thermal infrared imagery, color infrared and color aerial photography was made over the site and surrounding area. This remote-sensing survey served to document existing site conditions, assisted in the identification of vegetation assemblages, delineated areas of suspected existing stress or disease in these vegetation assemblages, and provided delineation of existing drainage patterns on and adjacent to the Grand Gulf site. The aerial survey was conducted by the Services Group of Texas Instruments, Inc. on October 2, 1972 before deciduous trees had lost their leaves.

6.1.6.2.1 Flight Schedule Each remote sensing mission, thermal infrared, color infrared and color photography, was conducted with specialized equipment during separate overfights which utilized various flight traverses and altitudes to ensure complete coverage of the study area.

a. Thermal Infrared. Predawn thermal infrared imagery was collected between the bours of 0630 and 0700 along five traverses flown in a NNE-SSW direction and one traverse in a NW-SE direction at an altitude of 6000 feet. The resulting imagery consisted of an original negative at an approximate scale of 1 inch =

3800 feet along the center track of the imagery, and enlarged prints at an approximate scale of 1 inch =

1900 feet.

b. Color Infrared. Color infrared photography was collected between the hours of 1300 and 1400 along six traverses flown in a NNE-SSW direction at an altitude of 4500 feet. The resulting imagery consisted of color infrared prints at an approximate scale of 1 inch = 1309 feet.
