OSHA sets 30-day interim for revised silica rule compliance assistance

OSHA has outlined initial enforcement protocol of its revised standard, Respirable Crystalline Silica Standard for General Industry and Maritime, most provisions of which become enforceable on June 23. The standard establishes a new eight-hour time-weighted average permissible exposure limit and action level, plus associated ancillary requirements.

During the first 30 days of enforcement, OSHA will offer compliance assistance for employers who make good faith efforts to abide the new exposure thresholds. “If upon inspection, it appears an employer is not making any efforts to comply, compliance officers should conduct air monitoring in accordance with Agency procedures, and consider citations for non-compliance with any applicable sections of the new standard,” notes OSHA Acting Deputy Assistant Secretary Galen Blanton in a memorandum to regional administrators. “Any proposed citations related to inspections conducted in this 30-day time period will require National Office review prior to issuance.”

The agency intends to issue interim enforcement guidance until a compliance directive on the new standards is finalized. OSHA’s Small Entity Compliance Guide for the Respirable Crystalline Silica Standard for General Industry and Maritime, posted here, discusses methods of compliance, such as using engineering and work practice controls, assessing exposure levels, respirator use, medical surveillance, and written exposure plans.
