Mississippi Damage Prevention Committee; amend.

SB 2365 updates Mississippi's excavation safety rules to include underwater utility lines (submerged facilities). It requires new marking standards for submerged lines (accurate within 15 feet), expands notice requirements for all excavations, and prohibits digging within protected zones without meeting specific conditions. The bill also creates special rules for large projects and sets deadlines for utility operators to fulfill their responsibilities. These changes directly affect construction crews, utility companies, and Mississippi 811 (the "call before you dig" service).
