Hazardous Materials Toolkit

The term hazardous materials refers to a broad category of hazardous wastes, hazardous substances and toxic chemicals with the potential to negatively impact human health or the environment. The presence or suspected presence of hazardous material with the potential to influence a transportation project creates a multitude of problems affecting right of way acquisition, project development and construction. Environmental practitioners can use these resources and tools to prepare materials associated with the management of hazardous materials during project development.
