Rulemaking news

MSHA has published the proposed silica rule on their website. Among other things, MSHA proposes to set the permissible exposure limit of respirable crystalline silica at 50 micrograms per cubic meter of air (µg/m3) for a full shift exposure, calculated as an 8-hour time-weighted average for all miners.

On January 4, 2023, the White House Office of Management and Budget (OMB) released the 2022 Unified Regulatory Agenda and Regulatory Plan (Fall 2022 Agenda) that reports on all planned rulemaking actions of administrative agencies. According to the Fall 2022 Agenda, the Department of Labor (DOL), Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration (MSHA) are pursuing a long list of thirty regulatory actions, similar to the Spring 2022 agenda, including the addition of a rule regarding Procedures for Use of Administrative Subpoenas in OSHA investigations.

On October 27, 2021, OSHA issued an Advance Notice of Proposed Rulemaking (ANPRM) on Heat Injury & Illness Prevention in Outdoor and Indoor Work Settings. 86 Fed. Reg. 59309 (Oct. 27, 2021). As announced in the ANPRM, OSHA is seeking information about the extent and nature of hazardous heat in the workplace and the nature and effectiveness of interventions and controls used to prevent heat-related injury and illness. Comments on the Proposed Rule must be submitted by December 27, 2021.

Because outdoor and indoor work settings that lack adequate climate-controlled environments pose a risk of hazardous heat exposure for workers, the proposed rule applies to both indoor and outdoor work environments.

The US Court of Appeals for the DC Circuit is currently considering a request by mine worker unions to require MSHA to create an emergency COVID-19 regulation. The parties have all finished submitting their briefs and now await a ruling. Husch Blackwell’s mine safety and health team represented national industry associations in filing an amicus (“friend-of-the-court”) brief to describe industry protections against the virus.

Just before the Labor Day holiday, the Mine Safety and Health Administration published a long-expected silica request for information (RFI) on possible further regulatory action to address silica (most often found as quartz) in workplaces. From past statements by current MSHA officials and the text of the RFI, it remains unclear how fast or how far MSHA may go in further the regulating exposures to one of the most commonly-found elements on Earth.
