Request for Coastal Zone Consistency Determination by Shell Offshore, Inc.

Shell Offshore, Inc. has filed notice of a proposed project which requires review by the MS Department of Marine Resources to ensure compliance with the state’s approved Coastal Program under the Coastal Zone Management Act.
