These standards strengthen the design, construction, maintenance, and repair of seals and monitoring and control of atmospheres behind seals in order to reduce the risk of seal failure and the risk of explosions in abandoned areas of underground coal mines.
The burden hours have been reduced by approximately 48,500 hours from the ETS. The major reason for this reduction is that the burden for sampling was incorrectly included in both the burden hours and burden costs. In addition, burden hours have been reduced because the requirement in the ETS for mine operators to file sampling protocols and action plans in the mine ventilation plan has been deleted from the final rule. Also, the requirement for mine operators to prepare for training was inadvertently included as burden hours in the information collection package that accompanied the ETS. Since the ETS, the final rule has added burden for: revising mine ventilation plans to allow for welding, cutting, and soldering activities; immediately notifying MSHA after an additional sample is taken under final § 75.336(c); evaluating the atmosphere in sealed areas to verify correct sampling locations; and labeling sampling pipes to indicate the location of the sampling point when more than one sampling pipe is installed through a seal.
