Such projects shall demonstrate the engineering and economic feasibility and practicality of various abatement techniques which will contribute substantially to effective and practical methods of acid or other mine water pollution elimination or control, and other pollution affecting water quality, including techniques that demonstrate the engineering and economic feasibility and practicality of using sewage sludge materials and other municipal wastes to diminish or prevent pollution affecting water quality from acid, sedimentation, or other pollutants and in such projects to restore affected lands to usefulness for forestry, agriculture, recreation, or other beneficial purposes.
Prior to undertaking any demonstration project under this section in the Appalachian region (as defined in section 14102(a)(1) and (b) of title 40), the Appalachian Regional Commission shall determine that such demonstration project is consistent with the objectives of subtitle IV of title 40.
The Administrator, in selecting watersheds for the purposes of this section, shall be satisfied that the project area will not be affected adversely by the influx of acid or other mine water pollution from nearby sources.
There is authorized to be appropriated $30,000,000 to carry out the provisions of this section, which sum shall be available until expended.
