be closer to $1.5 billion a year. In addi- tion, OSHA’s ancillary cost estimation of $9 million/year is much lower than the industry’s estimate of more than $90 million/year (Tables 1-2). Perhaps the largest issue is that it


is going to be difficult for metalcast- ers to meet the OSHA proposed PEL. According to OSHA’s data, a portion of the metalcasting industry already exhibits noncompliance with the current PEL (Table 3). More than 40% of facilities are noncompliant

with the current 100 µg/cu.m limit in three job categories: cleaning/finish- ing operators, sand system operators and abrasive blasting operators. More than 30% are noncompliant in furnace, knockout, pouring and maintenance operation. Te lack of compliance stems largely from the lack of a ready, cost-effective solution. OSHA’s cost analysis estimates include only the cost to reduce PEL from 100 µg/cu.m to less than 50 µg/cu.m and not the costs for those already above the current

limit to progress to the new, more stringent limit. Te disparity in costs goes hand in hand with the disparity in feasibility assumptions. OSHA’s numbers assume a few examples of workable methods in a handful of metalcasting facilities can be applied broadly across the entire industry with the same success. AFS and the industry contend this one- size-fits-all approach will not work, as dust sources are not the same at every facility. A significant portion of costs
