Coal combustion residuals; Chesapeake Bay watershed; closure.

Requires the owner or operator of any coal combustion residuals (CCR) unit, defined in the bill to include a coal ash pond or landfill, that is located in the Chesapeake Bay watershed to close such CCR unit by removing all of the CCR for (i) recycling, known as encapsulated beneficial use, or (ii) deposition in a permitted and lined landfill that meets certain federal standards. Any owner or operator that disposes of CCR in such a landfill is required to explain why recycling is not economically feasible. Such a closure project shall be completed within 15 years of its initiation and shall be accompanied by water testing or a connection to a municipal water supply for every residence within one-half mile.
