On December 22nd, 2017, the US Court of Appeals for the District of Columbia rejected all industry objections to the Occupational Safety and Health Administration’s (OSHA) respirable crystalline silica rule. Industry groups had asked the court to review the following five issues:
The court ruled that “OSHA has demonstrated technological feasibility for the typical firm in most operations and has supported that finding with substantial evidence, it has satisfied its burden and we must defer to its conclusions.” The court also determined that OSHA’s new rule is achievable, although it requested that OSHA review and revise its 30-day exposure requirement before medical testing is provided, or explain why the waiting period for testing is so long.
The General Industry compliance date for meeting the new 0.05 mg/m3 permissible exposure limit (PEL) for silica dust established by OSHA is June 23rd, 2018. This compliance date applies to rail loadout, transload and trucking operations that support the hydraulic fracturing industry. The compliance date for hydraulic fracturing operations is June 23rd, 2021, however, this compliance date does not prevent hydraulic fracturing operations from falling under the new directives if the 0.025 mg/m3 action limit (AL) is exceeded.
