Specifically, wo object to then portion of proposed Section 71.202 which geos beyond ACGIH rocoaunondotlons to provide that the eight-hour How weighted ovorags (TWA) con centration to which miners are exposed dwll not exceed two flbors por cubic centimeter of air. On July 7, 1972, following extensive hoorlngi whicR"sra o matter of public record, the Department of Labor, under SecHon 1910.93(e) of tho OSHA standard, sot tho Haw walghwd ovorogo limit at fhw flbors par ee, offfeaHvo July 2, 1972 through Juno 30, 1976.
