Research notes

TN regulates isolated wetlands at the state level even after Sackett v. EPA (2023) narrowed federal WOTUS jurisdiction — distinguishes TN from neighboring states. ARAPs issued or denied within 90 days. General permits cover bank repair, emergency infrastructure repair, gravel removal, maintenance, minor dredging, minor non-isolated wetland alteration, access structures, boat ramps. Federal conflict check: parallel federal Clean Water Act §404 USACE permit may also be required.
