Regional Implementation Agreement for Testing and Reporting Requirements for Ocean Disposal of Dredged Material off the Louisiana and Texas Coasts

This Regional Implementation Agreement (RIA) was prepared cooperatively by the U.S. Army Corps of Engineers (USACE), New Orleans District and Galveston District and EPA Region 6. The RIA provides guidance for applicants, permittees, and USACE and EPA staff working on ocean dredged material disposal projects in Louisiana and Texas. The RIA is necessary to adapt the national procedures, contained in the “Green Book,” to Regional situations and ensure compliance with the ocean dumping regulations. This RIA is designed to specify sampling, testing and reporting procedures for dredged materials proposed for ocean disposal in the Gulf of Mexico off the Louisiana and Texas coasts. In addition, this RIA establishes administrative, coordination and documentation procedures that will be followed by the USACE, New Orleans District and Galveston District, and EPA Region 6. This RIA revises and combines the existing RIAs for the Ocean Dumping Program in Louisiana and Texas, finalized in 1992. This RIA will supercede the 1992 RIAs upon finalization.
