| 00-16149 | Verification of Underground Coal Mine Operators' Dust Control Plans and Compliance Sampling for Respirable Dust | Proposed Rule | MSHA is proposing to revoke existing operator respirable dust sampling procedures under parts 70 and 90, and to implement new regulations that would require each underground coal mine operator to have a verified mine ventilation plan. Under this proposal, MSHA would verify the effectiveness of the mine ventilation plan for each mechanized mining unit (MMU) in controlling respirable dust under typical mining conditions. MSHA would collect full-shift respirable dust samples, called "verification samples," to demonstrate the adequacy of the dust control parameters specified in the mine ventilation plan in maintaining the concentration of respirable coal mine and quartz dust at or below 2.0 mg/m\3\ and 100 <greek-m>g/m\3\, respectively. The adequacy of these parameters would be demonstrated on shifts during which the amount of the material produced is at or above the "verification production level" (VPL) or the tenth highest production level recorded in the most recent 30 production shifts. The proposal would require mine operators to: First, set and maintain the dust control parameters during MSHA verification sampling at levels specified in the plan; second, maintain and make available to MSHA records of the amount of material produced by each mechanized mining unit during each production shift; and third, additional information in mine ventilation plans. For longwall mine operations, MSHA is also proposing to permit the use of either approved powered, air-purifying respirators (PAPRs) or verifiable administrative controls as a supplemental means of compliance if MSHA has determined that further reduction in respirable dust levels cannot be achieved using all feasible engineering or environmental controls appropriate for the operational conditions involved. In addition, through this rule, MSHA would conduct all compliance and abatement sampling under existing parts 70 and 90. | 2000-07-07 | 2000 | 7 | https://www.federalregister.gov/documents/2000/07/07/00-16149/verification-of-underground-coal-mine-operators-dust-control-plans-and-compliance-sampling-for | https://www.govinfo.gov/content/pkg/FR-2000-07-07/pdf/00-16149.pdf | Labor Department; Mine Safety and Health Administration | 271,288 | MSHA is proposing to revoke existing operator respirable dust sampling procedures under parts 70 and 90, and to implement new regulations that would require each underground coal mine operator to have a verified mine ventilation plan.
