The presidents of Palau, the Marshalls Islands and the Federated States of Micronesia say waste removal is a primary shared concern.
The three leaders agreed at a recent summit that they need a regional strategy for dealing with waste, and this should be in the Forum's Pacific Plan.
The leaders say a project to remove metal waste from Yap State in Micronesia will start within six months.
This project will then expand to the rest of the Federated States, the Marshall Islands, Guam and Saipan within a year.
On other issues, the three leaders agreed to push the United States to give more long-term funding for health contingencies.
They're also to push for a northern campus for the University of the South Pacific, and to set up a regional crime laboratory in Guam.
