Abstract
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.
