Relating to authorizing the Public Service Commission to promulgate a legislative rule relating to the occupancy of customer-provided conduit.

HB 4318 authorizes West Virginia's Public Service Commission (PSC) to create rules governing the use of "customer-provided conduit" - physical infrastructure (like underground pipes or conduits) owned by property owners or businesses, not utility companies. The bill formally approves an existing rule (150 CSR 37) that the PSC filed in March 2025, giving it legal authority to manage how this customer-owned infrastructure can be occupied or utilized. This directly affects utility companies needing access to such conduit for installations and property owners maintaining it. The key provision is the PSC's formal rulemaking authority over conduit occupancy, aiming to clarify usage standards.
