I T1TCj 11 j CHK j n. rs 1 I rtAK c J v In reply to your letter of January Uf 1978* requesting per mission to deregulate Building 1+20-U21 with respect to vinyl chloride, we feel that section 1910.1017 (a)(2) indicates the section of the standards does not apply to the handling or use of fabricated products made of polyvinyl chloride* URL 2 0 5 0 3 Polyvinyl chloride latex is already a fabricated product and unless as indicated in Section 1910*1017 (b)(6), the latex does not require further processing at temperatures and for times sufficient to cause mass melting of the polyvinyl chloride resulting in the release of vinyl chloride, a regulated area would not be needed* Section 19l0.101?(e)(l)(i) and (ii) indicates a reg-.lated area shall be established where polyvinyl chloride is used and vinyl chloride concentrations are in excess of the permissible exposure limit* Your data showing a minimum of 6,000 samples which average below the action level for 90 hour periods at monitoring points substantiates this interpretation, assuming the individual workers breathing zone is not closer to the source of materials than the monitoring point* Very truly yours, -TftfW NOTH BOWMAN Area Director *
