2.1.3 Environmental Studies and Clearance
In the early stages of project development of any highway project, consideration must be given to the social, economic, and environmental issues of the project. TxDOT is required to identify any social, economic, or environmental consequences on all projects. This is accomplished in cooperation and coordination with local, state and federal agencies and the public. During this process, decisions relative to public involvement or hearings and environmental requirements are necessary.
The three major categories of environmental study are:
- Categorical Exclusion (CE): For projects with a scope of work that is not anticipated to individually or cumulatively have a significant effect on the environment.
- Environmental Assessment (EA): For projects in which the significance of the impact on the environment is not clearly established.
- Environmental Impact Statement (EIS): For projects anticipated to significantly affect the environment.
