Senate Bill No. 452 aims to regulate the issuance of coastal use permits specifically for activities on Lake Maurepas. The bill enacts a new provision, R.S. 49:214.30(J), which prohibits the secretary or any approved local program from issuing coastal use permits for construction or work on the lake, with certain exceptions. These exceptions include the construction, creation, alteration, improvement, extension, or maintenance of wharfs, piers, docks, bulkheads, landfills, or other structures; the repair or replacement of existing pipelines or well facilities; and dredging or disposal of dredge material.

The proposed law retains existing regulations that allow for the issuance of coastal use permits for various activities within the coastal zone but specifically restricts these permits on Lake Maurepas to the outlined exceptions. This legislation is set to take effect on August 1, 2026.
