The Office is responsible for red flag investigations, Phase I & II environmental site assessments(ESA), remediation of contamination of discovered during construction, noise barrier assessments, air quality reviews, and the preparation/review of NEPA documents.

Within Environmental Policy there are two units: Document Review and Hazardous Materials.

The unit prepares and reviews Environmental Impact Statements, Environmental Assessments, and Categorical Exclusions. 

The Hazardous Materials Unit is responsible for responding to questions regarding the transportation, storage, and disposal of hazardous materials and wastes associated with INDOT construction projects. This unit provides advice on hazardous materials policy, operations, and regulation as well as providing a link between IDEM, consultants, the public, and INDOT project staff.  In addition, it prepares and reviews red flag investigations, Phase I ESA, and Phase II ESA for INDOT projects.
