Hazardous Materials

CDOT's Hazardous Materials Program helps manage contaminants and waste on highway projects and CDOT properties. Specialists ensure hazardous material sections of environmental documents comply with the National Environmental Policy Act (NEPA), are complete, and that contract specifications addressing hazardous waste and substances prepared for construction activities are accurate.

CDOT should identify and assess potentially contaminated sites while avoiding:

  • compromising health and safety,
  • incurring significant financial liability, and
  • minimizing involvement with substantially contaminated properties.

Other hazardous materials-related activities may include working with CDOT Property Management staff to assist in directing assessment, investigation and management of cleanup activities.
