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

Hurricane Execution Plan at Sector/Station Key West, Florida, Final Environmental Assessment

Sector and Station Key West


Sector Key West is a unified command consisting of six Fast Response Cutters, three small boat stations, an Aids to Navigation Team (ANT), and three staff departments. Sector Key West’s area of responsibility includes 55,000 square miles bordering the territorial seas of Cuba and the Bahamas. In September 2017, Sector Key West and Station Key West suffered extensive damage to many facilities from Hurricane Irma. To implement projects to mitigate the damage and close gaps in the existing infrastructure vulnerabilities, the USCG has developed alternatives to achieve the following three concurrent efforts:

• Rebuild Engineering Building (Building 105) at Sector Key West, Florida, to meet resiliency thresholds.

• Rebuild waterfront and shore facilities for Station Key West.

• Rebuild the electrical distribution system serving Sector Key West.

The U.S. Coast Guard (USCG) proposes to repair/replace facilities at Sector and Station Key West that were damaged by Hurricane Irma in September 2017. This environmental assessment (EA) was prepared in accordance with the National Environmental Policy Act (NEPA) (42 United States Code [U.S.C.] §§4321 et. seq.); Council on Environmental Quality (CEQ) Regulations for Implementing NEPA (40 Code of Federal Regulations [CFR] §§1500-1508), and associated CEQ guidelines; Department of Homeland Security Management Directive 023-01, Implementation of the National Environmental Policy Act; and Coast Guard Commandant Instruction (COMDTINST) 5090.1, U.S. Coast Guard Environmental Planning Policy.
