Public Notices, Meetings and Events in EPA's Pacific Southwest
EPA’s Pacific Southwest (Region 9) implements and enforces federal environmental laws in Arizona, California, Hawaii, Nevada, the Pacific Islands, and 148 Tribal Nations.
EPA’s Pacific Southwest Regional office encourages public participation in addressing environmental issues. When EPA hosts public meetings, events or other opportunities for public participation in the Pacific Southwest (Region 9) area, they will be found on this page. Public Notices will also be posted on this page. EPA provides public notices about regulatory and other actions it takes, often related to its permitting authorities. Many public notices seek comment (e.g., notices about proposed EPA actions) or participation from the public (e.g., public meeting notice); some are for informational purposes only (e.g., announcing a final rule). Some EPA actions will be included in the Public Notices listing and some will be included in the Federal Register listing. Please be sure to check both listings to find the notice you are seeking.
