Coal Mine operators are required to collect and submit respirable dust samples to MSHA for analysis. Pertinent information associated with identifying and analyzing these samples is submitted on the dust data cards that accompany the samples.
While the overall number of responses remains fairly steady, MSHA is projecting a decrease in the number of unique respondents due to the reduction in the less productive and marginal mining operations as coal prices and exports continue to decline. A slight increase in burden hours is due to the projected increase in the number certifications for dust sampling to more accurately reflect the number of individuals that were actually certified in the recent past. The increase in projected costs is due to the cost of sampling equipment, and related operational, maintenance and contract services cost increasing substantially since the last submission.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
