Silica Rule

With the enactment of OSHA's new Silica Rule in June 2016, companies engaged in roadway construction must be aware of the potential for exposure to silica associated with common roadway construction activities, mitigation strategies and technologies, and reporting, monitoring, and other regulatory obligations. Thanks to the decade of work by the Silica/Asphalt Milling Machine Partnership, use of OSHA-approved engineering control technologies can ensure compliance with the rule for roadway milling activities; however, other road construction and asphalt production activities may trigger the Silica Rule's monitoring and mitigation requirements. Contractors should be familiar with the new regulation and prepare for its enforcement on June 23, 2017, barring agency delay.
