The National Environmental Policy Act (NEPA) requires all Federal agencies to consider the impacts of proposed actions on the human environment and involve the public in the NEPA process. The Environmental Planning and Historic Preservation (EPHP) Team publishes all Environmental Impact Statements and Environmental Assessments of regional or national significance for public notice and comment. Interested parties can view recent draft and final NEPA documents below. Contact information for each project are included in each posting.

On April 23, 2019 CG-47 released the U.S. Coast Guard Environmental Planning Policy, COMDTINST 5090.1 (series) (EP CI) and the Environmental Planning Implementing Procedures (EP IP).  The EP CI mandates the use of the EP IP.  The two documents now align with the DHS NEPA policy, Implementation of the National Environmental Policy Act, Department of Homeland Security Instruction Manual 023-01-001-01 (series) and replace the old Coast Guard National Environmental Policy Act (NEPA) Implementing Procedures and Policy for Considering Environmental Impacts, COMDTINST 16475.1D, which has been cancelled. The EP CI and IP include significant changes to the Coast Guard environmental planning process and provide improved policy and procedures for complying with both NEPA and Environmental Effects Abroad of Major Federal Actions, Executive Order (EO) 12114.  Coast Guard members engaged in environmental planning efforts or taking actions that trigger NEPA or EO 12114 requirements must read both the EP CI and IP in order to implement their requirements effectively.  Significant changes from COMDTINST M16475.1D included in the EP CI and IP include but are not limited to:

  • Policy and procedures on the requirements of EO 12114.
  • Pre-planning process and notification requirements for NEPA and EO 12114.
  • Timing of compliance with other related environmental mandates (ESA, NHPA, etc.).
  • Requirements to track and report mitigation and monitoring commitments.
  • Requirement to establish formal agreements for providing environmental planning support.
  • Specific guidance for both the acquisitions and shore facilities management programs

U.S. Coast Guard Record of Decision and Programmatic Environmental Impact Statement and Overseas Environmental Impact Statement for the Offshore Patrol Cutter Acquisition Program

Offshore Patrol Cutter Acquisition Program (CG-9322)


The United States Coast Guard (Coast Guard) prepared this Programmatic Environmental Impact Statement/Overseas Environmental Impact Statement (PEIS/POEIS) to comply with the National Environmental Policy Act (NEPA) and Executive Order 12114, Environmental Effects Abroad of Major Federal Actions. The Coast Guard identified its need to address the current and long-term mission demand with a reliable and operationally available presence to accomplish assigned missions in offshore waters. Typical OPC operations would occur between 12 nautical miles (nm; 22 kilometers (km) from shore and inside 200 nm (370 km), but they can be deployed anywhere around the globe where national interests require. The Proposed Action would allow the Coast Guard to provide surface assets to bridge the operational capability gap between the National Security Cutters that patrol the open ocean and the Fast Response Cutters, which primarily operate within 50 nm (93 km) from shore to meet mission requirements and support the United States’ economic, commercial, maritime, and national security needs. In this PEIS/POEIS, the Coast Guard broadly analyzed potential impacts on physical, biological, and socioeconomic environmental resources resulting from proposed activities under the alternatives.

PEIS/POEIS originally published on June 23, 2022.  Record of Decision (ROD) added on September 23, 2022.
