Determination of Concentration of Responsible Coal Mine Dust Supporting Statements
The presentation is a general overview of the 2000 single sample and the 2003 plan verification proposed rules. The plan verification rule is designed to develop effective plans, provide for control of dust and the monitoring of the effectiveness of those controls. The single sample rule provides for a new finding. That finding is that the average concentration can accurately be measured over a single shift, contrary to what we currently have is that we have to average multiple samples. This presentation is available in HTML format, Powerpoint®, and PDF. |
