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

Final Environmental Assessment and Finding of No Significant Impact for the Waterfront Demolition Projects at Base Kodiak

By Shannon & Wilson CEU Juneau


The Coast Guard proposes to demolish in-water facilities at two sites on Base Kodiak, Alaska:

  • Marginal Wharf at the southwestern tip of the Nyman Peninsula in Inner Womens Bay, and
  • A seawater intake structure and concrete pile cap near the northeastern end of the Nyman Peninsula in Inner Womens Bay.

These existing facilities are derelict and obsolete, and present hazards to the natural environment, navigation, and public health and safety.  None of the facilities satisfy current or future planned USCG mission requirements.  No unmitigable significant impacts were identified for any of the alternatives in the EA.  Best management practices would be included as standard provisions of Coast Guard contracts and conservation measures developed during the federal permitting and approval processes would be employed, including those resulting from the completed Endangered Species Act consultation.  The preferred alternative will result in the loss of Marginal Wharf, a contributing resource to the Kodiak Naval Operating Base National Historic Landmark and therefore listed in the National Register of Historic Places.  Removal of the Marginal Wharf was determined an adverse effect and will be mitigated consistent with the memorandum of agreement currently under development with the National Park Service and the Alaska Office of History and Archaeology.
