Environmental Planning and Historic Planning

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

Draft Environmental Assessment for 2018 Hurricane Recapitalization of Station Fort Macon

The USCG proposes to construct a new Multi-Mission Station Facility to replace multiple onshore buildings at Station Fort Macon that were damaged during Hurricane Florence in September 2018. In addition to constructing a new facility, the USCG proposes to demolish existing hurricane-damaged facilities and permanently homeport an 87-foot coastal patrol boat (CPB) at Station Fort Macon. The Proposed Action is needed to address a shortfall in available functional and operational onshore facility space, as well as insufficient vessel basing, while meeting USCG mission and resiliency requirements. Comments on the Draft EA or inquiries regarding the document should be submitted during the 30-day comment period via postal mail or email to: Ron Baron U.S. Coast Guard 1240 E. 9th St, Room 2179 Cleveland, OH 44199
