  6. 30 CFR 56/57.5002Exposure Monitoring Dust, gas, mist and fume surveys shall be conducted as frequently as necessary to determine the adequacy of control measures

  7. Scope of 30 CFR 56/57.5002 Applicable to: • All MNM operations • Airborne contaminants: • Dust, gas, mist, and fume • Does not apply to: • Radon • Diesel particulate matter • Noise

  8. 30 CFR 56/57.5002 Improved Implementation of Surveys • Program Policy Letter was issued 10/22/2010 • http://www.msha.gov/REGS/COMPLIAN/PPLMEN.HTM • Mine operators have the primary responsibility for protecting the health of miners • Mine operators must demonstrate compliance rather than relying on enforcement interventions • Emphasize: • Plan • Prevent • Protect

  9. Policy • During MSHA inspections, MSHA inspectors will be evaluating operator survey activities • MSHA is providing additional information at the following website: www.msha.gov/S&HINFO/ExposureGuidance/ExposureGuidance.asp

  10. 56/57.5002 • Overexposures to airborne contaminants are indicators of inadequate control measures • Type of surveys • Frequency of surveys

  11. Are operators conducting surveys? • Quantitative surveys – exposure sampling to determine whether exposure is below the TLV, or wipe samples • Qualitative surveys • Site walk-through to evaluate control measures • Control technology inspection and maintenance (e.g., vehicle cabs, dust collectors, ventilation systems) • Documentation (records) • Visual inspection of area by inspector • Interviews with management and employees

  12. Adequacy of Surveys • Type: quantitative versus qualitative • Is exposure monitoring conducted in accordance with accepted analytical methods and techniques? • Is the person conducting the survey properly trained?

  13. Frequency of Surveys • Sampling results approach the TLV • Changes in mining operations (e.g. hazard or environmental agents) • Changes in control equipment used to reduce exposures. • Changes in work schedule (e.g. miners working longer shifts) or work procedures • Routine or special maintenance on controls • Miner complaints, illnesses, or disease

  14. Future Steps • Train inspectors • Outreach to stakeholders • Provide assistance to small mines • Training • Technical assistance with a focus on small mines
