Dear Ms. Purcell:
This is in response to your letter of July 19, requesting a written interpretation of the Occupational Safety and Health Administration's (OSHA) Occupational Exposure to Lead Standard; Final Rule, 29 CFR 1910.1025(e)(1), Table 1, published January 30, 1990 in the Federal Register.
The permissible exposure limit (PEL) for inorganic lead is 50 ug/m(3). At this time, employers in the non-ferrous foundry industry may use any combination of controls, including respirators, to achieve the 50 ug/m(3) limit. In addition, these employers must use administrative or engineering controls to the extent feasible, to achieve 200 ug/m(3).
Within five years from the date the United States Court of appeals for the District of Columbia Circuit lifts the stay on the implementation of paragraph (e)(l) for this industry, large non-ferrous foundries, those with 20 or more employees, are required to achieve the 50 ug/m(3) PEL by means of engineering and work practice controls. However, within five years of the lifting of the stay, small non-ferrous foundries, those with fewer than 20 employees, will be required only to achieve a 75 ug/m(3) level using engineering and work practice controls. The Agency has found that this control requirement is economically feasible for small non-ferrous foundries. In order for the small non-ferrous foundries to meet the 50 ug/m(3) PEL in accordance with 29 CFR 1910.1025(e)(2), engineering and work practice controls instituted to achieve 75 ug/m(3) must be supplemented with respirators.
We hope this information clarifies your uncertainties with the standard. Should you require further interpretations of this or other OSHA standards, please contact the following office:
