Stabilizing Soil on Your Property – What to Expect

October 19, 2023

Maui gives so much to the world. As guests, we are honored to give our support back.

  • EPA teams will apply a soil stabilizer on the ash footprint of burned structures, in coordination with local officials.
  • EPA may apply the stabilizer on properties before residents are able to return.



What Will Happen Before Soil Stabilizer is Applied

  • EPA teams will check the property and surrounding are for wildlife, animal feeders, and plants
  • A cultural monitor will accompany the teams to ensure any historic structures and other areas known to have cultural artifacts or ancestral ashes are not sprayed

What You’ll See on Your Property After Soil Stablizer is Applied

  • A thin, clear crust on the surface of sprayed materials
  • The thin crust is see-through and easily broken apart
  • Soil stabilizer is non-toxic when dry


| Ash and debris may contain harmful contaminants that can impact human health and the environment. If you re-enter the burn area, please take the necessary precautions to protect yourself and others such as wearing the provided protective gear and thoroughly reviewing your re-entry packet. |

| To remove Soiltac® from the surface of an object, run it under hot water or steam the surface then wipe with a soft cloth |


Before Soil Stabilizer

✗ Plants and vegetation

Commonly Asked Questions

Can I request to not have soil stabilizer applied?

No. Soil stabilizer will be applied to all properties in Lāhainā to protect public health and the environment.


Is Soiltac® harmful to human health?

EPA reviewed the ingredients of Soiltac® to confirm:

  • It is non-toxic when dry
  • Applying a soil stabilizer is more effective at protecting public health and the environment than leaving ash and debris as-is


Is Soiltac® a microplastic? Will it add microplastics to the environment?

  • While Soiltac® (when dried and hardened) meets the federal definition of a plastic, EPA does not anticipate it being broken into pieces so small that it could be considered a microplastic.
  • Soiltac® will be removed with all ash and debris as part of Phase 2 of the cleanup and disposed of safely.
