Proposed Guam Ocean Disposal Site EIS
On this page:
Guam currently has no ocean disposal site for dredged material. Consequently, maintenance and new-construction dredging projects have had to manage all their material on land or in near-shore fills. Appropriate on-land or near-shore disposal and reuse sites are limited in their capacity to appropriately manage dredged material. Therefore EPA is now proposing to designate a new ocean disposal site for clean (non-toxic) dredged material offshore of Guam.
Intensive field studies have been conducted to help identify locations where disposal of clean dredged material would not have any significant impact to the marine environment, or to other human uses of the ocean. The results of those studies are reflected in EPA’s draft Environmental Impact Statement for Designation of an Ocean Dredged Material Disposal Site Offshore of Guam. The draft EIS is now available, along with key supporting documents. They can be downloaded below.
EPA is accepting public comment on the draft EIS through October 6, 2009.
