## Abstract

This final rule amends an existing safety standard to allow the use of low- and medium-voltage diesel-powered electrical generators as an alternative means of powering electrical equipment in underground coal mines. The final rule eliminates the need for mine operators to file petitions for modification to use these portable generators to power electrical equipment and does not reduce the protections afforded miners by the existing standards, in fact it increases protections.
