Ongoing Environmental Reviews at PMRF

 


PMRF Environmental Analyses Overview

The National Environmental Policy Act – or “NEPA” – is a U.S. law that requires federal agencies to identify and analyze the potential environmental effects of a proposed action before deciding whether to proceed with that action. The law encourages and facilitates public involvement to inform decision makers on actions that may affect the community or the environment.

 

NEPA can involve different levels of analysis such as:

 

  • An Environmental Impact Statement – or an “EIS” – is a detailed public document providing an assessment of the potential effects a federal action may have on the environment. An EIS may be required by NEPA for the examination of the individual and cumulative, or additive, environmental effects of the agency’s proposed activities.  

 

  • An Environmental Assessment – or an “EA” – may be the appropriate level of analysis, depending on the project. When preparing an EA, the agency will use the findings of the analysis to determine the next steps in the NEPA process. If it is found that significant impacts would result, which could not be mitigated to less than significant levels, then the preparation of an EIS would be needed.


Multiple Navy environmental reviews are underway for projects on or offshore of Kaua‘i. The Navy carefully and scientifically analyzes the effects its actions may have on the human, natural, and cultural environments. If there is an impact, the Navy strives to avoid, reduce, or mitigate those impacts.


When a proposed action triggers Hawai‘i Revised Statutes Chapter 343 (the state law governing preparation of an Environmental Assessment or Environmental Impact Statement, commonly referred to as the Hawai‘i Environmental Policy Act "HEPA"), compliance with HEPA is required.

 
Projects are listed by in-water or on-land and not in any particular order. When applicable, projects contain links to standalone websites for more information.

 

In-Water Projects

  1. Hawai‘i-California Training and Testing EIS/OEIS (U.S. Pacific Fleet) 

The Navy proposes to conduct at-sea military readiness activities within the Study Area and to modernize and sustain Navy ranges necessary to support training and testing activities. This action is needed to ensure U.S. military services are able to organize, train, and equip service members and personnel to meet their national defense missions.

Projected Schedule:

    • Scoping Phase: December 2023-January 2024 (completed)
    • Draft EIS/OEIS Public Review and Comment: December 2024-February 2025 (completed)
    • Decision Document: December 2025
  1. PACDERMA System Project – Underwater Electromagnetic Measurement System Testing EA (NAVSEA) 

The Navy proposes to construct underwater electromagnetic measurement system to characterize a submarine’s submerged electric signature.

Projected Schedule:

    • Draft EA Public Review and Comment: August 2025
    • Decision Document: October 2025

 

Land-Based Projects

  1. Open Floodable Space EA (PMRF, Navy Region Hawai‘i) 

The proposed action is to manage a 200-acre open floodable space adjacent to the interior northern portion of PMRF Barking Sands to manage and mitigate sea level rise encroachment on installation grounds and surrounding agricultural lands. The open space would include an additional 200-acre buffer to provide suitable habitat for native plants and animals.

  1. Integrated Natural Resources Management Plan EA (PMRF, Navy Region Hawai‘i) 

The Navy proposes to implement the 2023 INRMP, which provides management recommendations to protect species, land, waterways, wetlands, and floodplains.

Projected Schedule:

    • Draft EA Public Review and Comment: May-June 2024 (completed)
    • Decision Document: March 2025 (completed)
  1. PMRF Land-Based Training and Testing EA (U.S. Pacific Fleet)  

The Navy proposes to conduct ongoing and proposed military readiness land-based training and testing activities at PMRF launch areas and other locations. This action is needed to 1) ensure U.S. military services are able to organize, train, and equip service members and personnel to meet their respective national defense missions; 2) update NEPA compliance for ongoing land-based training and testing activities; and 3) provide additional coverage for other military services’ activities at PMRF.

Projected Schedule:

    • Draft EA Public Review and Comment: August-September 2024 (completed)
    • Decision Document: 2025
  1. PMRF and Kōke‘e Park Geophysical Observatory Real Estate EIS (Department of the Navy, PMRF, NASA)  

The Navy proposes to maintain long-term (over 25 years) Department of Defense use of 8,172 acres (684 acres of leasehold; 7,488 acres of easement lands - approximately 95 percent of the easement lands are passively used for encroachment buffers and mission readiness, the remaining 5 percent of easement lands are used for access and utilities easements) of State of Hawaiʻi lands on Kauaʻi for operational continuity and sustainment of the military readiness mission. NASA proposes to maintain long-term (over 25 years) use of 23 acres (16 acres of leasehold; 7 acres of easement lands) of State of Hawaiʻi lands for continued operation of KPGO. The Proposed Action is needed because the existing real estate agreements for these lands are set to expire between 2027 and 2030. The Navy use of these state lands is required to maintain technological and safety capabilities supporting PMRF training and testing. Navy training and testing operations do not occur on these state lands. The environmental effects of these training and testing operations are fully analyzed in previous, focused environmental documents referenced in the EIS. For NASA, these state lands are critical to maintain data collection efforts of global significance.

This is a joint NEPA/HEPA document: The applicants are preparing a single EIS compliant with both the Hawaiʻi Environmental Impact Statements law (HRS Chapter 343) and the National Environmental Policy Act as allowed under HAR §11-200.1-31. The HRS Chapter 343 triggers are: 1. Propose the use of state or county lands, HRS section 343-5(1); 2. Propose any use within any land classified as a conservation district, HRS section 343-5(2). 

Projected Schedule:

    • Scoping Phase: May-June 2024 (completed)
    • Draft EIS Public Review and Comment: June-August 2025
    • Decision Document: May 2026
