Environmental Policy

The Environmental Policy Office is dedicated to ensuring that INDOT is compliant with the National Environmental Policy Act (NEPA) and hazardous material requirements. The Office is responsible for red flag investigations, Phase I & II environmental site assessments (ESA), remediation of contamination 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 Site Assessment & Management. The Document Review Unit is responsible for ensuring that Indiana’s transportation projects comply with federal and state requirements for environmental documentation, including NEPA, the state Environmental Policy Act, and associated regulations. The unit prepares and reviews Environmental Impact Statements, Environmental Assessments, and Categorical Exclusions.
