Based on a model of the interaction of blood lead levels and air exposure developed by the Center for Policy Alternatives at the Massachusetts Institute of Technology, OSHA believed it had resolved the issue of scientific uncertainty that had plagued the hearings on the proposed lead standard (OSHA, 1978a, p.

Extended periods would be required for redesign of the production process. The primary lead indust~ was given 10 years to achieve the engineering controls necessary to reach the mandated airlead levels, and the secondary lead smelter and lead battery industries were given five years (OSHA, 1978a, p.

From page 74... ...
Blood levels over 80 ,ug/100 g, which had been found in earlier studies in 16 percent of workers in the secondary smelting industry, 6 percent of workers in battery plants, and 2 percent in primary smelters, were practically unobserved in workers in the post-standard period. Finally, dramatic changes in the proportion of workers found to have blood lead levels in the 60-80 fig/ 100 g range had also been observed.
