Senator Mike Sirpoy of Lee’s Summit sponsored Senate Bill 4, legislation that seeks to modify and create new provisions relating to utilities and focuses on natural gas.

Senator Tracy McCreery of St. Louis County expressed concern during floor discussion that provisions described in the bill — including references to "PISA and future test year" in the transcript — could raise utility rates for constituents. "When I look at this legislation, [I] think that this legislation, especially PISA and future test year, are gonna raise utility rates for, you know, our constituents," McCreery said.

The Senate set Senate Bill 4 aside for future discussion; the transcript records the item being "set aside for future discussion" but does not show a roll-call vote or amendment. The sponsor noted that "all parts of this bill... have been on bills in the senate in the past, many multiple times," indicating that some provisions have appeared in prior measures.

The transcript does not provide a fiscal estimate, specific statutory citations tied to the utility provisions, or the precise mechanism by which the bill would change natural‑gas regulation or rates. No committee referrals or next‑step actions were specified in the recorded floor remarks.

Senators indicated they would return to the measure at a later time for additional debate or action.
