Interoffice Communication To : Distribution From : Dave Mahler Date : October 18, 1983 Subject : 1983 COMPREHENSIVE VCM LEAK SURVEY I A Attached are the results of the 1983 Comprehensive VCM Leak Survey. A total of sixty-three (63) leaks were found. Sixty-two of these leaks have been repaired to date; the one remaining leak (903 compressor seal water valve) be repaired when a spare valve is received at the Plant.
