Wetlands State Resource Locator


Note: Most states have enacted laws and regulations to protect wetlands. In many cases, these rules are established to define the state's role in the "404 permit/401 certification process." This process involves the U.S. Army Corps of Engineers and your state environmental agency. To learn more about the wetlands permitting process go to the CICA /Permit page.

Primary State Wetlands Web Page. This web page should explain the state wetlands program and provide links to various wetlands resources.

Construction Permit Process - State Rules

  • How Are Wetlands Activities Regulated by Mississippi? The Mississippi Department of Environmental Quality (DEQ), Office of Pollution Control and Mississippi Department of Marine Resources administer the state's wetland policy. Specifically, the Department of Marine Resource has authority to issue permits under the Coastal Wetlands Protection Act and the DEQ issues water quality certifications under ? 401 for discharges into waters of the U.S. located in Mississippi.

  • Mitigation Measures. A permit can be conditioned to ensure the applicant incorporates any mitigation measures that the program requires.
