Wetland Regulations
Under Section 404 of the Clean Water Act, consideration must be given to the impact of a construction project on wetlands. Impacts should be avoided or minimized where practicable. Where impacts cannot be avoided, permitting and compensatory wetland mitigation may be necessary. The United States Army Corps of Engineers (USACE) manages Section 404 oversight in Oklahoma. In order to ensure compliance with regulations, developers should consult relevant guidelines and coordinate with the Tulsa District of the USACE regarding the following:
- Identifying any wetlands present at the project site
- Determining if wetlands are jurisdictional and protected by Section 404,
- Developing plans that will either avoid or minimize impacts to wetlands,
- Acquiring the necessary permits if jurisdictional wetlands will be impacted, and
- Designing, executing and monitoring wetland mitigation if necessary.
- Additionally, activities where a 404 Permit is required, are potentially subject to a Section 401 Certification completed by the Oklahoma Department of Environmental Quality (ODEQ).
For more information developers should coordinate with the USACE directly:

Frequently Asked Questions
How can I determine if my project will impact a wetland?
While an on-site visit is often necessary to determine with certainty if a wetland is present or not present, The National Wetlands Inventory (NWI) mapper is an excellent tool that can provide preliminary information on the location of wetlands.
Is the wetland my project will impact protected under section 404 of the Clean Water Act?
The OCC has no regulatory authority but can help Oklahomans navigate regulatory requirements. A formal delineation and jurisdictional determination are needed to establish if a wetland is protected by the Clean Water Act. The United States Army Corps of Engineers, Tulsa District, Regulatory Program can provide further information about federal regulations.
My project will impact a jurisdictional wetland, what options do I have for mitigation?
OCC can help connect you to resources that may assist with locating available mitigation credits or identify suitable locations for restoration. Please contact us.
