In collaboration with the Coal Diesel Partnership and the National Institute for Occupational Safety and Health, MSHA formed the Diesel Issue Resolution Team at MSHA's Approval and Certification Center (A&CC). Major technical issues affecting the implementation of Diesel Particulate Matter (DPM) filtration technology on both permissible and non-permissible vehicles in underground coal mines were identified. The following Action Table provides the Coal Mining Community with background information on specific diesel issues and actions taken by MSHA to resolve them. A&CC contacts that can provide you with more information are listed. Enforcement questions and issues should be directed to Melinda Pon, 202-693-9516, Pon-Melinda@dol.gov or Bob Thaxton, 202-693-9515, Thaxton-Robert@dol.gov.
