APPENDIX C NRC SAFETY EVALUATION FOR ONSITE DISPOSAL OF SLIGHTLY CONTAMINATED CONSTRUCTION SOIL in May 1993, the NRC approved a permit under 10 CFR 20.302 to allow Boston Edison Company to dispose of construction soil containing small amounts of cobalt-60 and cesium-137. This soil was disposed of via onsite bunal at a location on Boston Edison property adjacent to the Pilgrim Station meteorological tower Dose calculations performed as part of the permit application and within the NRC Safety Evaluation concluded that the maximum dose from the disposal area would be less than 0.1 mrem / year during the year
. of disposal. Doses during subsequent years through the time of site decommissioning would be less than 0.01 mrem / year. Such exposure levels are considered insignificant relative to radiation dose arising from nrturally-occurring sources of radiation and radioactivity, and other exposure pathways arising from operation of Pilgrim Nuclear Power Station.
Complete details regarding the NRC permit for disposal, and the accompanying NRC Safety Evaluation, can be found in NRC Docket No. 50-293, APPROVAL UNDER 10 CFR 20.302(a) RELOCATION AND PLACEMENT OF CONSTRUCTION SOIL WITH TRACES OF RESIDUAL RADIOACTIVITY ON SITE AT
- PILGRIM NUCLEA R POWER STATION (TAC NO M85501)", dated May 4,1993.
