OSHA has floated several “regulatory alternatives” to its proposed new standards to reduce worker exposures to crystalline silica, offering industry and other stakeholders a chance to justify other options in reaching the goals of the rulemaking.

Some safety and health stakeholders argue that cost-benefit data included in OSHA's newly proposed crystalline silica standard show undue pressure on the agency to conduct economic analyses of new regulations that ultimately do not factor into whether it moves forward with key rulemaking priorities.

Industry sources say OSHA's newly released proposed rule to reduce worker exposures to crystalline silica, given its breadth across business sectors and the reach of the standard, could represent the biggest OSHA proposed regulation in terms of impact on business since the agency's abortive effort to regulate ergonomic hazards in the late 1990s.
