MDEQ – Mississippi Department of Environmental Quality

Mississippi Department of Environmental Quality

We are currently assessing the impact of the US Supreme Court ruling in the case of Sackett v. Environmental Protection Agency on the permitting process in Mississippi.

During this period, it should be assumed that any wastewater discharge that was previously permitted will still necessitate obtaining permits through MDEQ. If you have any inquiries regarding this matter, please reach out to the Environmental Permitting Division by clicking the link.
