The Pacific Islands large aquatic ecosystem is composed of the U.S. territories of Guam, the Commonwealth of the Northern Mariana Islands (CNMI), and American Samoa. Guam and CNMI, both of the Mariana Islands, are located within Micronesia Region of the Western Pacific Ocean. American Samoa is located in the Polynesia Region of the South Pacific. The economy of the three territories is driven by tourism, the U.S. military, and fishing.
There are 14 TRI facilities in the Pacific Islands: 9 in Guam, 1 in American Samoa, and 4 in the Northern Mariana Islands on the island of Saipan. TRI air releases are primarily from electric utilities, with sulfuric and hydrochloric acid composing the greatest emissions. Federal facilities are the main source of nitrate releases to the water as well as lead and copper disposal or other releases to land. The ecology of these territories is monitored by the Region 9 EPA, as well as local EPA and DEQ offices in the territories.
