Senate Bill No. 390, introduced by Senator Allain, mandates the creation of a digital mapping system for all utility systems in Louisiana, both public and private. The Louisiana Public Service Commission (LPSC) is tasked with securing information from utility providers, including those offering electricity, water, natural gas, and wastewater services, to compile a comprehensive statewide map. The bill stipulates that the costs associated with mapping and locating these utilities will be borne by the utility system owners. Additionally, the LPSC is authorized to promulgate necessary rules and regulations and may establish a grant program aimed at preventing damage to existing utilities and ensuring proper documentation.

The bill outlines a timeline for completion, requiring that the mapping project be finalized by December 31, 2032, with the digital map achieving a minimum accuracy rating of 85%. Before implementation, the rules and regulations developed by the LPSC must be reviewed and approved by the Joint Legislative Committee on the Budget after being assessed by the relevant House and Senate committees. The bill will take effect upon the governor's signature or after the designated period for gubernatorial action.
