The Environmental Protection Agency has proposed changing the regulations for disposal of dredging materials in Puerto Rico. As it stands Puerto Rico has five disposal sites near San Juan Harbor Yabucoa Harbor Ponce Harbor Mayaguez Harbor and Arecibo Harbor. Each of those can only receive dredged material from the specific harbor for which it is named. The EPA would modify these restrictions so that each disposal site could receive materials from other harbors as well although each disposal activity would still need to be approved by the EPA. This change will allow for more flexibility for disposal in the future. Comments on the change could be made at the website regulations.gov until Nov. 13.
