Maui Wildfires

Maui is a culturally and geographically unique part of the United States. EPA is on Maui as part of a multi-agency emergency response to the wildfires that occurred 2023, working under mission assignments from the Federal Emergency Management Agency (FEMA). As EPA works to support the recovery, agency staff and contractors have attended cultural training collaboratively developed by non-profit, government (Office of the Mayor), and community leaders (Kumu Hōkūlani Holt). EPA has consulted with local residents throughout its work regarding historic, cultural, and archaeological considerations.

Background

On August 8, 2023, high winds and dry weather caused wildfires to develop in Lāhainā, Upper Kula, Upper Makawao and Olinda on the island of Maui. These wildfires affected approximately 1,550 parcels, 2,200 structures and were one of the deadliest U.S. wildfires in at least the past 100 years.

EPA personnel worked with federal, state, and local government partners on response and recovery efforts. Federal Emergency Management Agency (FEMA) tasked EPA with addressing hazardous material removal, water infrastructure technical assistance, and sustainability assistance during the recovery process.

Wahikuli Subdivision Sewer Design Project

EPA, with the County of Maui Department of Environmental Management, announces the availability of the Draft Environmental Assessment (Draft EA) and Anticipated/Proposed Finding of No Significant Impact for the Wahikuli Subdivision Gravity Sewer System project located in Lahaina on the Island of Maui.

The Draft Environmental Assessment (pdf) can be accessed at the State of Hawaii Office of Planning and Sustainable Development Environmental Review Program’s The Environmental Notice website.

Please submit comments via email no later than May 23, 2025.

EPA plans to discuss the Draft EA at the May 7 Lahaina Community Meeting. Please visit MauiRecovers.org for details about this meeting.

This initiative comes in response to a request from the County of Maui for Federal Emergency Management Agency (FEMA) technical assistance. Through FEMA funding, EPA was asked to provide support with planning and designing a proposed gravity sewer system for the Wahikuli subdivision, which comprises approximately 230 properties currently serviced by individual wastewater systems, including cesspools and septic systems.

The scope of work for this project includes:

• Conducting an environmental review, including cultural and biological consultations, and seeking public input on the proposed project.
• Drafting pre-construction design, with public input opportunities, and engineering plans.
• Holding regular meetings with the County of Maui and providing periodic public updates.

Hazardous Materials Removal: Completed

The EPA hazardous material removal team completed its work on December 21, 2023. EPA crews removed more than 200 tons of hazardous materials from 1,400-plus properties in fire-impacted areas. After hazardous materials were removed, a soil stabilizer was applied to prevent ash and debris from migrating off properties due to surface water run off or wind. Additionally, more than 30 tons of lithium batteries from 94 electric and hybrid vehicles and 274 power walls were safely collected from the impacted area and shipped off Maui for recycling.

Water Infrastructure: Completed

EPA deployed Water Emergency Team (WET) members to provide on-the-ground guidance and technical assistance for stormwater, wastewater, and drinking water for the County of Maui. EPA continues to actively support the County’s Departments of Public Works, Environmental Management, and Water Supply.

Sustainability Assistance

EPA received a mission assignment from FEMA for a long-term recovery Sustainability Advisor to assist in rebuilding communities and restoring watersheds with the aim of building resilience to future climate change impacts and disasters. The Sustainability Advisor is collaborating with local and state departments and federal agencies to understand local priorities and identify potential funding sources for long-term recovery.

Additional Resources

FEMA has established a website with current wildfire disaster information and resources. The page features response and recovery information and serves as the platform for related information from the Department of Homeland Security.
