Step 3: Dispose of wastes according to law, to limit liability and protect the environment
Depending on the substance, you may need to dispose of the material in accordance with state and federal hazardous waste disposal laws. If hazardous materials are simply disposed of with other construction debris, they can be released into the environment at the construction site, during transit, or even eventually from the landfill site. Willful or negligent violation of hazardous waste laws can result in civil or criminal penalties.
Some wastes may require disposal in a hazardous waste landfill. If the material can be recycled, you can seek a nearby recycling site using the earth911 form on http://baywise.org.
