The Environmental Protection Agency’s director of resource conservation and recovery, Suzanne Rudzinski, stated in a declaration filed October 11 in the U.S. District Court for the District of Columbia that it would take at least one year to complete revisions of the toxicity characteristic and toxicity characteristic leaching procedure regulations. Revisions to the toxicity characteristic may have an effect on other Resource Conversation and Recovery Act rulemakings, including proposed coal ash regulations.
