Summary: Santee Cooper, a public-power utility, supports the EPA's proposal to allow a new pathway for certifying closure by removal of legacy CCR impoundments. However, they argue that the EPA should eliminate or revise the "cognizant regulatory authority" requirement, as it arbitrarily excludes sites where closure was completed under state oversight but the initial mandate predated the 2015 CCR Rule.
