Scientists released a study July 27 finding that surface impoundments that store coal ash are responsible for 21 damage cases and $2.3 billion in damages to wildlife over the last 45 years. The report, Wildlife and Coal Waste Policy Debate: Proposed Rules for Coal Waste Disposal Ignore Lessons From 45 Years of Wildlife Poisoning, advises that regulating coal ash under Subtitle C of the Resource Conservation and Recovery Act could save $3.85 billion in ecological damages over the next 50 years. The Environmental Protection Agency will issue a final rule on coal ash management within the year.
