MSHA's standards for sealing abandoned areas in underground coal mines includes requirements covering the design and construction of new seals and the maintenance and repair of all seals.
Records that will be collected under this rule will help assure that the construction and maintenance of seals are done correctly; certified persons conducting sampling in sealed areas are adequately trained; and results from sampling in sealed areas are recorded, so that problems can be found and fixed.
The number of producing underground coal mines has decreased from 301 to 242. In addition, the percentage of sealed areas with seals of less than 120 psi strength continues to decrease as operators build new, stronger seals. Due to the decrease in respondents, responses decreased as well from 54,857 to 15,800, and burden hours decreased from 6,380 to 3,525. Response time increased for annual burden hours and to notify MSHA under section 75.336(c) but this increase in burden hours did not offset the overall decrease in burden hours. Costs decreased from $1,510,674 to $1,068,083.
