HB 1923 -- Mountaintop Removal Coal Mining Sponsor: Low This bill prohibits any investor-owned electric utility operating a coal-fired generating unit located in this state that produces electricity from purchasing or using coal extracted by mountaintop removal coal mining. Upon a petition of an electric public utility, the Missouri Public Service Commission is required to approve an annual rider to the utility's rates to recover all reasonable and prudent incremental costs incurred by the utility as a result of purchasing or using coal extracted by a method other than mountaintop removal coal mining.Copyright (c) Missouri House of Representatives
