EPA’s Pacific Islands Office (PIO) works with the U.S. territories in the Pacific Ocean, including Guam, American Samoa, the Commonwealth of the Northern Mariana Islands (which includes Saipan, Rota, and Tinian), and Wake Island. To a lesser extent we work with the former trust territories and now Freely Associated States of Palau, the Marshall Islands, and the Federated States of Micronesia.
