Editor’s Note: The GAO Mine Safety Report GAO-14-345, “Basis for Proposed Exposure Limit on Respirable Coal Mine Dust and Possible Approaches for Lowering Dust Levels,” found here, assesses MSHA’s decision to “not use NIOSH’s surveillance data as the basis for its proposed new coal mine dust limit…” and instead base their proposal on other available data. GAO’s assessment of the agency’s data selection decision indicates that their auditing standards are consistent with OIRA’s government-wide data quality requirements.
Below is are two excerpts from the GAO report.
