The Colorado Department of Health and Environment (CDPHE) is the entity that can issue these sort of waivers. Typically, only landfills with specific operations intended for asbestos mitigation are certified to accept that type of material. For this specific case, CDPHE issued a temporary waiver to Front Range Landfill for 60 days to accept debris from the Marshall Fire. The Town was consulted by CDPHE and ultimately supported the decision.
To be clear, just because this waiver is in place, this does not guarantee that asbestos will indeed end up in the landfill. It is not clear how many, if any, of the homes that were damaged or destroyed in the Marshall Fire had any asbestos within them. This waiver allows for bringing this debris to the closest landfill, Erie, for expediting cleanup of the devastation, regardless of the presence of asbestos.
