DOL’s Office of Workers’ Compensation Programs proposed to revise regulatory standards applicable to self-insurance by coal mine operators under the Black Lung Benefits Act. The rule proposed updating the requirements needed for a coal-mine operator to self-insure. It also set the security posted requirement at 120% of an operator’s projected black lung liability, promoting adequate coverage of benefits’ payments regardless of an operator’s financial health. These proposed changes were intended to shift the responsibility of benefits payments under the Act from taxpayers to coal-mine operators.
