The U.S. Environmental Protection Agency (EPA) was assigned by the Federal Emergency Management Agency (FEMA) to handle the removal of hazardous materials from properties affected by the wildfires. EPA completed work in December to remove and dispose of hazardous waste from properties affected by the wildfires. The focus areas for the removal of hazardous materials were Lahaina, Kula, and Olinda, and all work was completed in December.

Hazardous materials removed included compressed gas cylinders, pesticides, fertilizers, and ammunition, as well as lithium-ion batteries, particularly solar battery storage on homes.

After the removal of hazardous materials, other agencies will step in to remove solid waste, debris, and ash in the affected areas.
