The TDOT Environmental Division is comprised of six (6) offices:

The Environmental Analysis Office includes our NEPA Section, Archaeology Section, Historic Preservation Section, Hazardous Materials Section, and Air/Noise Section. They are responsible for the preparation of environmental documents required for federal and state funded transportation projects, along with the assessment of impacts on transportation projects within communities through the identification and protection of historical and archaeological resources, analysis of air quality & noise impacts, and avoidance of hazardous material sites. This office compiles and collates information on various social, economic and environmental areas for all transportation projects.  

The Environmental Compliance Office  combines the responsibilities of the Compliance and Field Services Program and the MS4 and Facilities Compliance Program into one cohesive unit. The goal of this office is to provide oversight, training, and technical expertise necessary for environmental compliance for TDOT construction activities and for TDOT facilities. This office also ensures corrective actions for environmental issues. 

The Ecology and Permits Office is responsible for reviewing and analyzing project plans, addressing any impacts and acquiring all environmental permits needed for transportation projects. Environmental permits for impacts to wetlands, streams and rivers are obtained from various federal and/or state regulatory agencies. This office is also responsible for obtaining coverage under the National Pollutant Discharge Elimination System (NPDES) Construction Storm Water Permit, for all transportation projects that will disturb one or more acre of land during construction.

The Highway Beautification Office encompasses a varied group of programs ranging from regulatory control and oversight of outdoor advertising to preserving, sustaining and enhancing the beauty of our Tennessee landscape. "Keep Tennessee Beautiful" is more than a phrase. It involves the dedication and effort of everyone to ensure the roadside beauty found in Tennessee remains for the enjoyment of future generations.

The Environmental Mitigation Office is responsible for establishing compensatory mitigation to offset transportation project impacts to streams, wetlands, and species.  These compensatory mitigation mechanisms include establishment of permittee-responsible mitigation sites and/or agreements with mitigation sponsors, development of advanced mitigation sites, and purchase of advanced credits from third party sponsors.  In addition, this office is responsible for the design and implementation of compensatory mitigation plans, as well as ensuring that all mitigation projects are developed and documented in accordance with applicable state and federal regulations and guidance.
