These testimonies of the ECOS Officers before the U.S. House of Representatives Committee on Appropriations Subcommittee on Interior, Environment, and Related Agencies and U.S. Senate Committee on Appropriations Subcommittee on Interior, Environment, and Related Agencies address the FY18 Budget for the U.S. EPA, specifically regarding the Categorical Grants within the State and Tribal Assistance Grants (STAG Categorical Grants). Please note that the testimony to the Senate is the same as that to the House but with a different heading and submission date.
