The U.S. Environmental Protection Agency (EPA) consists of ten regions throughout the United States which include 50 states, 572* federally recognized Indian Tribes and intertribal consortia, and U.S. territories. EPA's Pacific Southwest (Region 9) works to protect public health and the environment in the southwestern United States (Arizona, California, Nevada, and Hawaii), territories of the South Pacific, and 146* federally recognized tribes in the Pacific Southwest.
The Tribal Office of the Region 9 Water Division administers Clean Water Act (CWA) grants for over 90* tribes in the Pacific Southwest. These grants are used for surface and groundwater monitoring, assessment, cleanup, and protection, as well as assistance for wastewater infrastructure and for prevention of polluted runoff. The purpose of this booklet is to inform the public about Region 9's tribal CWA Section 106 program and highlight successful tribal CWA 106 programs in the Pacific Southwest.
