[Date Due] 6/1/2012 [Status] Completed [Corrective Action Taken] On May 24, 2012, MSHA and NIOSH experts held an in-person meeting to discuss MSHA's proposed revised rock dust sampling method, which involves several substantial improvements from previous practice and meets the goal of the internal review recommendation. This proposed method takes into consideration recent research regarding sample collection methods, and MSHA is continuing to work with NIOSH on refining it. [Recommendation] 
The Administrator for Coal should collaborate with the Director of Technical Support and NIOSH to develop a standard method for collecting mine dust samples for operators and inspectors to use to determine compliance with 30 CFR 75.403. The Agency should consider recent research regarding sample collection methodology, including that related to sample depth and elevated surfaces.
