On March 28, the Environmental Protection Agency (EPA) received a technical report from the Electric Power Research Institute (EPRI) on coal ash pond closings. The report addressed the 2010 proposed rule on closing ponds within 180 days of final delivery of coal ash, and it said the time limit should be set around site-specific conditions. It also explained a safe closing takes time in order to gradually decrease water pressure; industry stakeholders previously said the 180 day limit was not realistic.
