Description: In this letter, the Association of States and Territorial Solid Waste Management Officials (ASTSWMO) respectfully requests that the U.S. Environmental Protection Agency’s Office of Underground Storage Tanks (EPA OUST) address the decline in federal funding to State and Territorial (State) underground storage tank (UST) programs. The funding provided currently does not meet the necessary level for the effective implementation of. State UST programs. Since fiscal year (FY) 2013, the overall level of extramural funding for the UST release prevention and cleanup programs has decreased with no adjustment for the increase in regulatory requirements or inflation. A summary of these trends is provided in the letter.
