; (7) conducting and completing studies or assessments to project how climate change may impact the sustainability of water systems; or (8) developing and implementing mitigation measures to rapidly address impacts on water systems most susceptible to abrupt climate change, including those in the Colorado River Basin and coastal regions at risk from rising sea levels. (c) Application To be eligible to receive a grant from the Administrator under subsection (b), the owner or operator of a water system shall submit to the Administrator an application that— (1) includes a proposal of the program or strategy to be planned, designed, implemented, or maintained by the water system; (2) cites the best available research or data that demonstrates— (A) the risk to the water resources of the water system as a result of ongoing or forecasted changes to the hydrological system brought about by factors arising from climate change, including rising sea levels, temperature changes, and changes in precipitation levels; and (B) how the proposed program or strategy would perform under the anticipated climate conditions and demonstrates no adverse environmental impacts; and (3) explains how the proposed program or strategy is expected to enhance the resiliency of the water system, including source water protection for community water systems, to these risks or reduce the direct or indirect greenhouse gas emissions of the water system. (d) Competitive process (1) In general Each calendar year, the Administrator shall conduct a competitive process to select and fund applications under this subsection. (2) Priority requirements and weighting In carrying out the process, the Administrator shall— (A) prioritize funding of programs or strategies the applications for which— (i) are submitted by the owners or operators of water systems that are, based on the best available research and data, at the greatest and most immediate risk of facing significant climate-related negative impacts on water quality or quantity
