(2) USNRC Regulatory Guide 4.8 (March, 1976)

Dear Sir Pursuant to Section 50.59 of the Commission's Rules and Regulations, Yankee Atomic Electric Company hereby proposes the following modifications to Appendix A of the Technical Specifications which are effective 1 January 1977.

+

PROPOSED CHANGE: Table 4.7-4, " Environmental Monitoring Program", shall be changed as per revised pages 3/4 7-25 and 3/4 7-26, enclosed. This revision proposes to expand the scope of the radiological surveillance program to include locally grown foodstuffs. An increase in the number of air, soil, milk and direct radiation sampling points and a decrease in the number of water and river sediment sampling points is suggested as well as reduced sampling frequencies for selected samples and analyses.

REASON FOR CHANGE: A second air particulate, iodine, and direct radiation (TLD) control station is suggested in Heartwellville, VT, (7.7 mi, 320 ).

This location is topographically similar to the area around, Rowe, Massachusetts, yet should not be influenced by the plant. The additional data obtained from operating this station should allow a more accurate estimate of the ambient radiation background. Quarterly composites for each station will be subjected to gamma isotopic analysis as per Table 2, proposed Regulatory Guide 4.8.

Since all of the upstream river water passing through Harriman Station is obtained from Harriman Reservoir, sarpling both of these sources is redundant. Hence, only one background sample is suggested in this revision, which will be identified as Harriman Reservoir v ter. Additionally, the two plant storm drains will continue to be monitored, but the radionuclide content of this water will be reported in effluent and waste disposal reports rather than offsite monitoring reports. The type and frequency of analyses is consistent with Table 2, proposed Regulatory Guide 4.8.

The fo6d surveillance program will be expanded-to include farm or garden products which are locally grown in significant quantities.

Soil will be monitored at air particulate monitoring sites and five additional _ locations. The present sampling frequency will be reduced to once per 3 years because experience with the present intensive program as well as special studies such as EPA Report PB-205-640 (Kahn, et. al.,19~1) have not demonstrated accumulation or deposition of plant-related radio-nuclides in soils. This sampling frequency is consistent with Table 2, proposed Regulatory Guide 4.8.

Vegetation sampling will be carried out at or near sampling locations in order to provide possible correlations between areal deposition and air concentrations of radionuclides.

River sediment sampling sites will be reduced because the present program contains an excessive number of control stations. Moreover, selected indicator stations will be dropped because the information derived from the present intensive sampling program as well as specialized studies such as EPA Report PB-205-640 do not indicate the accumulation of radio-nuclides in sediments outside of Sherman Pond and No. 5 Station Pond.

Consequently, these two sites have been chosen for continued monitoring because they are sensitive indicators of radionuclide deposition. A third site will be selected to monitor sediments further downstream. A control y

station will be maintained at Harriman Reservoir and on the North River.

The sampling frequency and types of analyses are consistent with Table 2, proposed Regulatory Guide 4.8.

An additional milk indicator station is suggested (Lively Farm, Heath, MA, 3.6 mi, 100 ). The revised sampling frequency allows for monthly sampling during the grazing season and quarterly monitoring for the period when milk animals are fed stored feed.

The sampling points for fish and aquatic plants are not changed.

However, the sampling frequency has been revised as a result of monitoring experience. This suggested frequency coincides with Table 2, proposed Regulatory Guide 4.8.

SAFETY CONSIDERATIONS: The attached radiological surveillance program has been designed to be more effective in documenting the behavior and impact of normal and abnormal releases of radionuclides in all significant air and water pathways.

This submittal has been reviewed by the Yankee Atomic Nuclear Safety Audit and Review ~(NSAR) Committee.

SCHEDULE OF CHANGE: This change to the Technical Specifications will be implemented within ninety (90) days of Commission approval.
