Letter to MSHA Requesting an Extension of the Comment Period for the Proposed Silica Rule
On July 13, 2023, The Mine Safety Health Administration (MSHA) published a proposed rule, “Lowering Miners' Exposure to Respirable Crystalline Silica and Improving Respiratory Protection.” (Silica Standard). The Silica Standard provides for a public comment period of 45-days, which expires at midnight eastern time on August 28, 2023. The National Stone Sand & Gravel Association (NSSGA) requests an extension of the public comment period for an additional 60-days and proposes that the public comment period be extended until midnight eastern time on October 27, 2023.
