The Federal Highway Administration (FHWA) assigned TxDOT some FHWA NEPA responsibilities for environmental review, consultation or other actions required under federal environmental law that pertain to the review or approval of a specific highway, railroad, public transportation and multimodal projects. The responsibilities were assigned under the Surface Transportation Project Delivery Program (assignment program) codified at 23 USC 327.

The assigned responsibilities are subject to the same procedural and substantive requirements as previously applied to FHWA. The assignment program does not preempt or interfere with any power, jurisdiction, responsibility or authority of an agency, excluding FWHA, under applicable law and regulations.

When TxDOT became responsible for the assigned responsibilities, the TxDOT Environmental Program was updated to address the assignment program requirements. The tools in the TxDOT Environmental Compliance Toolkits explain or satisfy the requirements of the TxDOT environmental review process, which includes the assignment program requirements.
