The regulations govern how the Office of Workers' Compensation Programs (OWCP) administers the Energy Employees Occupational Illness Compensation Program Act of 2000, as amended (EEOICPA), 42 U.S.C. 7384 et seq. Since July 31, 2001, OWCP has administered the provisions of part B of EEOICPA that were not assigned to the Secretary of Health and Human Services, to the Secretary of Energy, or to the Attorney General by Executive Order 13179. Part B of EEOICPA provides for the payment of lump-sum compensation and medical benefits to Department of Energy (DOE) employees and certain of its contractors and subcontractors (or their survivors) who sustained an occupational illness due to exposure to radiation, beryllium, or silica. Part B also provides for medical benefits and a supplemental lump-sum payment to awardees under section 5 of the Radiation Exposure Compensation Act (RECA), 42 U.S.C. 2210 (note). Since October 28, 2004, OWCP has also administered part E of EEOICPA, which provides for the payment of additional monetary compensation (based on permanent impairment and/or wage loss) and medical benefits for DOE contractor employees (or their survivors) and uranium miners, millers and ore transporters covered by section 5 of the RECA (or their survivors) who sustained a covered illness due to exposure to a toxic substance while working at a DOE facility, or a uranium mine or mill covered under section 5 of RECA.
