Occupational Safety and Health Administration 2006 – Federal Register Recent Federal Regulation Documents

The Occupational Safety and Health Administration (OSHA) is amending the existing standard which limits occupational exposure to hexavalent chromium (Cr(VI)). OSHA has determined based upon the best evidence currently available that at the current permissible exposure limit (PEL) for Cr(VI), workers face a significant risk to material impairment of their health. The evidence in the record for this rulemaking indicates that workers exposed to Cr(VI) are at an increased risk of developing lung cancer. The record also indicates that occupational exposure to Cr(VI) may result in asthma, and damage to the nasal epithelia and skin. The final rule establishes an 8-hour time-weighted average (TWA) exposure limit of 5 micrograms of Cr(VI) per cubic meter of air (5 [mu]g/m\3\). This is a considerable reduction from the previous PEL of 1 milligram per 10 cubic meters of air (1 mg/10 m\3\, or 100 [mu]g/ m\3\) reported as CrO3, which is equivalent to a limit of 52 [mu]g/m\3\ as Cr(VI). The final rule also contains ancillary provisions for worker protection such as requirements for exposure determination, preferred exposure control methods, including a compliance alternative for a small sector for which the new PEL is infeasible, respiratory protection, protective clothing and equipment, hygiene areas and practices, medical surveillance, recordkeeping, and start-up dates that include four years for the implementation of engineering controls to meet the PEL. The final standard separately regulates general industry, construction, and shipyards in order to tailor requirements to the unique circumstances found in each of these sectors. The PEL established by this rule reduces the significant risk posed to workers by occupational exposure to Cr(VI) to the maximum extent that is technologically and economically feasible.

OSHA solicits public comment concerning its request for an extension of the information collection requirements specified by its Process Safety Management of Highly Hazardous Chemicals Standard (29 CFR 1910.119).

This document gives notice of OSHA's approval of a change to the state of Oregon's occupational safety and health state plan to exclude coverage of private sector contractors at Crater Lake National Park. Accordingly, Federal OSHA will exercise enforcement authority over such employers. OSHA is amending its description of the state plan to reflect this change in the level of Federal enforcement in the state.
