Subject:
Virgil C. Summer Nuclear Station Docket No. 50/395 Revised Environmental Information
Dear Mr. Denton:
As requested by Mr. Edvard F. Branagan, Jr., South Carolina Electric and Cas Company provides revised land use information for /ppendix I evaluation.
This information was reverified on March 6, 1981. Also enclosed is a draft map of existing radiological monitoring locations for both NRC required and other non-required but existing sampling sites. This map's blue overlay (the distance annular rings) are incorrectly located and is in the process of being corrected.
Should you require further information, please let us know.
Very truly yours, T. C. Nichols, Jr.

g (1)The nominal lower limit of detection is defined in HASL 300 (Rev. 8/74), pp. D-v8-01, 02, 03 at the 95%
confidence level. The LLD levels are decay corrected to the end of the total sampling period. The LLD i
for radionuclides analyzed by gamma spectrometry will vary according to the number of radionuclides en-countered in environmental samples. These LLD levels will be used as minimum criteria for objectives for instrumentation and analytical procedure selection.
