Utilities may clean coal to meet NSPS

The revised NSPS, established by the Environmental Protection Agency (EPA) in 1979 in accordance with the 1977 amended Clean Air Act, could make cleaning of steam coal a necessity within this decade at some utilities for which scrubbing will be inadequate. These regulations apply to utility boilers with heat-input rates greater than 250 multiplied by 10**6 Btu/hr and on which construction began after Sept. 18, 1978.
