New respirable dust regulations that are intended to reduce the incidence of black lung disease among miners take effect today, over the objections of the National Mining Association (NMA), which calls them “one-size-fits-all approach” that won’t deliver real worker protections.

The National Mining Association (NMA) has asked a federal appeals court to review the Mine Safety and Health Administration's (MSHA) regulation for the control of coal dust in underground coal mines, contending that the rule “embodies fundamental legal and technical infirmities in its scope, foundation and framework.”
