Section 2: Interagency Coordination/Permits

Anchor: #i1008219


Early coordination with regulatory and resource agencies allows for identifying and assessing project potential to affect jurisdictional interests of other agencies. Regulatory agencies have permitting requirements for proposed construction activities in their jurisdictional areas.

This section discusses the activities involved in identifying permit requirements, through coordination with agencies during early project development, so required permits can be obtained.

This section includes the following two tasks:

3100. Perform early coordination with review/resource agencies

3110. Determine environmental permit requirements

3100: Perform early coordination with review/resource agencies

Description. During early project planning, regulatory/resource agencies should be contacted (see the Environmental Manual) and notified to obtain input, concerns, or opportunities regarding the project.

Pertinent Project Types. Projects requiring environmental documentation.

Responsible Party. Environmental coordinator


  • Obtain mailing list of agencies. Consider those listed under potential permits in the TxDOT Environmental Manual.
  • Coordinate task work with Environmental Affairs Division if necessary.
  • Send letter of notification and request for input to agencies.
  • Begin discussions regarding environmental mitigation. (See 3390: Prepare environmental mitigation plans).

Helpful Suggestions.

  • Include a project location map and any information that helps produce a project specific response versus a generalized information response.
  • Consider conducting field investigations with resource agencies and discuss issues in the field.

Critical Sequencing. This coordination should be initiated after field investigations are conducted.

Authority Requirements.

  • Memorandum of Understanding with TNRCC
  • Memorandum of Understanding with TPWD
  • Memorandum of Understanding with Texas Historical Commission.

3110: Determine environmental permit requirements

Description. Regulatory agencies have permitting requirements for proposed construction activities. The scope of work should include the need for obtaining permits to comply with federal and state regulations governing activities within, or close to, the project area.

A list of potential environmental permits is shown in the TxDOT Environmental Manual.

Additional, miscellaneous permits may be required. (See 5080: Obtaining miscellaneous permits). The permits are listed in a table of miscellaneous permits in the TxDOT Plans, Specifications, & Estimate Manual, Chapter 1, Section 2, Permits.

Pertinent Project Types. All projects except preventive maintenance or restoration projects.

Responsible Party. Environmental coordinator

Critical Sequencing. Determine permit requirements through early coordination with review agencies so design/construction requirements may be considered during schematic design.

Authority Requirements.

  • National Environmental Policy Act of 1969, as amended
  • Endangered Species Act
  • National Historic Preservation Act of 1966
  • Clean Water Act
  • River and Harbor Act of 1899
