During rulemaking in 2016, Utah's UST rules were reviewed by representatives from the US Environmental Protection Agency (EPA) to ensure that the changes Utah proposed to incorporate the 2015 EPA UST regulations would not jeopardize Utah's ability to receive State Program Approval (SPA) from EPA. In reviewing the rules, EPA suggested that references to cleanup standards for CERCLA sites should be removed from Rule R311-211, or the rule should state that the CERCLA requirements are outside the scope of the Resource Conservation and Recovery Act (RCRA) program.
