Regulated Area for East-end of Block I - Support Data
Attached is a table showing the VCM exposure values from four sampling points in Block I. #2, #3, #4 and #5.
This table I, is identical to table II of a letter dated June 14, 1979 except that sampling point #1 is omitted. This was done to possibly reduce the size of the regulated area in Block I.
Monthly averages after omitting point #1 were as follows:
March
April May June
1.03 ppm VCM .8344 ppm VCM
.95 ppm VCM .926 ppm VCM
