Improving and Eliminating Regulations; Calibration and Maintenance Procedures for Coal Mine Respirable Dust Samplers

We (MSHA) have revised and updated our Informational Report No. 1121 (IR 1121) to include currently approved sampling equipment and to permit the use of fast-response calibrators having a volumetric tube. The updated document is Informational Report No. 1240 (IR 1240) entitled, ``Calibration and Maintenance Procedures for Coal Mine Respirable Dust Samplers.'' This final rule updates the existing incorporation-by-reference of IR 1121 in MSHA's coal mine respirable dust standards to reference IR 1240.
