The Department of the Air Force (DAF) has formally announced its intent to prepare an Environmental Impact Statement (EIS) for the proposed basing of a KC-46A Pegasus tanker squadron at Selfridge Air National Guard Base (SANGB) in Macomb County, Michigan. This crucial step marks the beginning of a comprehensive federal review process to assess the environmental, social, and economic implications of modernizing the 127th Wing's aerial refueling mission. The DAF's action signals a significant upgrade to strategic air capabilities, transitioning from the aging KC-135T Stratotanker fleet to the more advanced KC-46A Pegasus.
The Strategic Imperative for Modernization
The primary objective behind this proposed action is to equip the DAF with a more capable and mission-effective aerial refueling squadron at SANGB. The current fleet of eight KC-135T Stratotankers, which have been a workhorse for decades, faces increasing operational and logistical obsolescence. This modernization effort is explicitly driven by a strategic imperative to align the 127th Wing's mission with the broader National Defense Strategy. Replacing the KC-135s with KC-46s is seen as essential for maintaining and enhancing the nation's air refueling capacity in a rapidly evolving global security landscape.
Proposed Action and Alternatives Under Review
The DAF's proposed action involves basing a squadron of up to eight KC-46 aircraft at SANGB, directly replacing the existing eight KC-135T aircraft. However, the EIS will not solely focus on this singular proposal. As part of its due diligence, the DAF will also thoroughly analyze at least two alternatives. The first alternative, labeled Alternative 1, considers basing up to 12 KC-46 aircraft at the installation. This option would represent an even greater expansion of capabilities. The second, mandatory alternative is the No Action Alternative. This scenario would examine the implications of not proceeding with the KC-46 basing and continuing with the current KC-135 fleet, providing a baseline for comparison. The EIS aims to provide decision-makers and the public with a clear understanding of the potential outcomes of each scenario.
Scope of Environmental Analysis
The EIS will undertake a rigorous assessment of various resource areas to understand the potential environmental consequences of the KC-46 beddown, its operations, and the associated infrastructure construction. These areas of analysis include:
- Airspace considerations
- Noise impacts, particularly from aircraft operations
- Air quality, including emissions
- Biological and natural resources
- Cultural resources
- Water resources
- Geological resources
- Land use and noise compatible land use planning
- Socioeconomic impacts on the surrounding communities
- Hazardous materials and waste management
- Infrastructure and utilities, including necessary upgrades
- Transportation and aircraft parking
- Community services
- Aesthetics
The DAF has identified potential significant impacts related to aircraft noise, air quality, and land use as key areas requiring detailed examination. Furthermore, the DAF has recognized that the proposed action has the potential to be located within a floodplain. This acknowledgment triggers an early notice to responsible state and federal agencies in accordance with Executive Order (E.O.) 11988, which pertains to Floodplain Management. The DAF also confirmed its intent to obtain any necessary permits or authorizations and to consult with federally recognized Native American Tribes and other federal agencies possessing relevant jurisdiction or special expertise.
Public Participation and Scoping Process
A critical component of the EIS process is public involvement. The DAF has initiated a 30-day public scoping period, beginning on May 21, 2026. During this period, the DAF actively solicits substantive comments from interested parties. These comments are crucial for identifying alternatives, potential impacts, relevant information, studies, or analyses that should be addressed in the EIS.
The public can submit comments online via the project website, www.selfridgekc46eis.com, by email to [email protected], or through postal mail to the NEPA Project Manager, Ms. Kristi Kucharek, P.O. Box 31645, Knoxville, TN 37930-1645. While comments will be accepted throughout the EIS process, submitting them within the 30-day scoping period ensures the DAF has ample time for consideration. The DAF anticipates releasing the Final EIS in Spring 2027, following a comprehensive review of all input and analyses. The scoping process is designed to ensure that the EIS is as thorough and inclusive as possible, reflecting the concerns and insights of local, state, and federal agencies, tribes, and the general public.
