Wheeler November 4, 1983 v" CP2 - Epidemiology V/-/4- Proposed Phase II Vinyl Chloride Study Tom I'm sending you a copy of my comments on the EHA Vinyl Chloride proposal In response to your handwritten note to Nick Wheeler. Please note that It Is still only a proposal not an approved activity as my October 28th memo may have Implied. You Inquired about costs. If we follow-up the old cohort, the principal cost will be this departments time In attending meetings of the CMA group. If we identify a new cohort, amount needed for computer time might reach $10 N, although we would need to better assess the work Involved before providing a sound estimate. Either way, we need authorization to spend about $2 M more just to complete Phase I. SGA/ls Attachment Tusan 6. Austin, sc.d.
