(a) Water supply restoration projects are those that protect, repair, replace, construct, or enhance facilities related to water supplies, including water distribution facilities and treatment plants that have been adversely affected by coal mining practices. If the adverse effect on water supplies referred to in this section occurred both prior to and after August 3, 1977, the project shall remain eligible, notwithstanding the criteria specified in §12.803 of this title (relating to Eligible Coal Lands and Water), if the Commission finds in writing, as part of its eligibility opinion, that such adverse effects are due predominately to effects of mining processes undertaken and abandoned prior to August 3, 1977.     
      (b) Enhancement of facilities or utilities under this section shall include upgrading necessary to meet any local, state, or federal public health or safety requirement. Enhancement shall not include any service area expansion of a utility or facility not necessary to address a specific abandoned mine land problem.
