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

Proposed Dredge Activities at the U.S. Coast Guard Yard, Baltimore, Maryland



The USCG proposes to perform maintenance and improvement dredging at the USCG Yard in Baltimore, MD. Proposed dredging would occur offshore in Curtis Creek, and would include the Shiplift area and turning basin in front of the CG Yard, the vessel berth areas between Piers 1, 2, and 3, and the navigation channel from the CG Yard to the Interstate 695 bridge (i.e., Bascule Bridge). The Preferred Action Alternative is described in the Final Environmental Assessment (EA). The overarching need for the Proposed Action is to provide the necessary water depths to operate the Syncrolift facility located in the Shiplift area, which is used for maintenance and repair at the CG Yard; and to address insufficient water depths within the navigation channel to accommodate the new Offshore Patrol Cutter and National Security Cutter. The USCG proposes to complete dredging in order to maintain the viability of the Syncrolift facility, support the operation and service of the new cutters, and meet USCG mission requirements. As the only USCG shipyard, the CG Yard needs to be accessible and have the appropriate facilities to conduct maintenance of its own fleet.
