The Environmental Protection Agency (EPA) is issuing this rule under the Resource Conservation and Recovery Act (RCRA), Subtitle I-- Regulation of Underground Storage Tanks. This rule limits the regulatory obligations of lending institutions and other persons who hold a security interest in a petroleum underground storage tank (UST) or in real estate containing a petroleum underground storage tank, or that acquire title or deed to a petroleum UST or facility or property on which an UST is located. This final rule specifies conditions under which these ``security interest holders'' may be exempted from the RCRA Subtitle I corrective action, technical, and financial responsibility regulatory requirements that apply to an UST owner and operator. This rule should result in additional capital availability for UST owners, many of whom are small businesses, and will assist them in meeting environmental requirements by improving their facilities.
