In 1999, MSHA published new Health Standards for Occupational Noise Exposure. The rule took effect on September 13, 2000. This page is a single source page for all documents and resources related to this new rule to protect miners from hearing loss. Most of the documents are in PDF format.
As of August 2, 2004, MSHA has published Program Information Bulletin P04-18 "Technologically Achievable, Administratively Achievable, and Promising Noise Controls (30 CFR Part 62)".
