House Bill No. [insert number] introduces additional requirements for coastal use permits specifically for activities on Lake Maurepas and Lake Pontchartrain. The bill enacts R.S. 49:214.43, which establishes a submerged lands protection standard that mandates applicants to provide comprehensive scientific studies and documentation for activities such as pipeline trenching, platform construction, dredging, and geophysical surveys. The department responsible for issuing permits must make written findings supported by scientific evidence, ensuring that the proposed activities minimize disturbance to submerged lands, do not permanently alter lake bottom contours, and do not adversely affect sediment transport or benthic productivity.

Furthermore, the bill requires independent scientific review of permit applications, with reviewers selected by the department and funded by the applicant. It also mandates public hearings in the affected regions, allowing for community input and requiring the department to address any scientific or technical concerns raised during these hearings. The administrative record must include all relevant documentation and findings to support the department's final decision. This legislation aims to enhance environmental protection and ensure sustainable management of Louisiana's coastal resources.
