OSHA's new crystalline silica rule was finalized March 24. It reduced the permissible exposure limit (PEL) to silica in half, from 100 µg (micrograms)/cu.m to 50 µg/cu.m. Here is what you need to know about the rule. AFS is committed to a silica regulatory policy based on sound science that protects its workers, is technologically and economically feasible, and does not impose compliance costs that far exceed its expected benefits.

The Convincing Case Against OSHA's Silica Rule

Brief Rundown of the Final Rule Provisions

Watch the AFS Webinar on OSHA's Final Rule and its Impact on Metalcasters (Download the PDF of the webinar here.)

As the new silica rule imposes a significant reduction in the PEL and requires metalcasting facilities to adopt extensive engineering and work practice controls to limit silica exposures over other available technology, compliance with the new rule will require substantial investment per plant without a guarantee that your facility can actually comply with the new requirements.  

AFS and the National Association of Manufacturers asked the U.S. Court of Appeals for the 5th Circuit Court to review the silica rule. The request was filed through AFS’ affiliated Texas Chapter.  After all petitioners have filed, the court that ultimately hears the case will set a briefing schedule. Should we prevail at the Circuit Court, OSHA would likely appeal to the U.S. Supreme Court or come to a settlement agreement with all of the parties who litigate this rulemaking.
