The Mine Safety and Health Administration's standards and regulations for diesel-powered equipment in underground coal mines serve to protect coal miners who work on and around diesel- powered equipment. The internal combustion engines that power diesel equipment expose miners to fire and explosion hazards in the confined environment of an underground coal mine, which contains combustible coal dust and highly explosive methane gas.
A reduction of 85 burden hours (from 708 to 623) reflects a reduction due to a previously reported training burden that should not have been included, and an increase in the number of respondents (from 148 to 165). The number of responses decreased by 591 (1004 to 413) since the first year included an inventory of all equipment and this submission includes only changes to equipment. A reduction in the burden cost (from $8,000 to $6,409) was a direct result of the correction in previously reported training costs.
