ENVIRONMENTAL EVALUATIONS / Construction of C-40A Aircraft Maintenance Hangar

Revised DRAFT ENVIRONMENTAL ASSESSMENT
FOR CONSTRUCTION OF A C-40A AIRCRAFT MAINTENANCE HANGAR AT
MARINE CORPS BASE HAWAII, KANEOHE BAY, OAHU, HAWAII

The U.S. Navy has prepared an Environmental Assessment (EA) in accordance with the National Environmental Policy Act (NEPA) and applicable regulations and guidance. The Draft EA was originally circulated for public review from May 17, 2023 to June 16, 2023. Substantive public comments were received that required the Action Proponent to review the proposed action and potential construction and operations impacts. The Draft EA has been revised and will be recirculated for another formal public review. The Proposed Action is to construct an aircraft maintenance hangar for new U.S. Naval Air Force Reserve VR-51 C-40A aircraft on Marine Corps Base Hawaii (MCBH). VR-51 is a tenant on MCBH. Although the transition to the C-40A aircraft has already occurred, the Revised Draft EA analyzes impacts associated with construction of a maintenance hangar, in addition to operational impacts of the C-40A.

A copy of the Revised Draft EA is located below in the "DRAFT EA DOCUMENTS" section of this web page and at the following website: https://planning.hawaii.gov/erp/environmental-notice/. The Revised Draft EA will be available for a 30-day public review and comment period beginning on March 08, 2025. All comments must be in writing and postmarked or emailed on or before April 07, 2025. Your comments will be considered as part of the decision-making process. Comments are most useful when they identify one or more of the following:

• Errors in the analysis.
• New scientific information that would have a bearing on the analysis.
• New or additional information that could affect the outcome of the analysis.
• Requests for clarification.

Public comments, including names and street addresses of respondents, may be included in the Final EA. Individual respondents may request confidentiality. If you wish to withhold your name or street address from public review or from disclosure under the Freedom of Information Act, you must state this at the beginning of your comments. Such requests will be honored to the extent allowed by law. All submissions from organizations or businesses, and from individuals identifying themselves as representatives or officials of organizations or businesses, will be made available for public inspection in their entirety. All comments must be in writing and postmarked or emailed on or before April 07, 2025.
