Summary

NEW INSTRUMENT found during 2026-08-20 MO maintenance docket re-read (not previously on file). House Bill 3362, with companion HB 3364 (Sponsor: Costlow, Mike (108); LR No. 7308H.01I; same title and same 3/30/2026 hearing, confirmed from house.mo.gov this gate), sponsored by Rep. Colin Wellenkamp (R-St. Charles) and Rep. Mike Costlow (R-Dardenne Prairie), introduced Feb. 2026; house.mo.gov's own bill-tracking page describes it as creating 'new provisions for industrial utility users.' It would require large-load customers, including data centers, to pay the costs of providing them electricity (grid infrastructure upgrades among them) and would add a DNR permit requirement for large water users; reporting describes it as building off SB4 (mo-sb4-2025). The bill was referred to the House Committee on Conservation and Natural Resources on 3/24/2026 and that committee held its only hearing on it 3/30/2026, 1:00 PM, House Hearing Room 7 (a warm reception per the sponsor -- "We had tremendous testimony, almost exclusively in support of" -- but no committee vote). MO GATE 2026-08-20: CORRECTED: the row previously said the hearing was held by the House Special Committee on Intergovernmental Affairs. The House's own bill-actions and bill-hearings records show the referral and the 3/30/2026 hearing were Conservation and Natural Resources. Intergovernmental Affairs is Rep. Tricia Byrnes's committee, which announced the SEPARATE Sept. 16, 2026 data-center hearing that was later canceled; the two were conflated. Per house.mo.gov as fetched 2026-08-20, the bill did NOT advance in the 2026 regular session: 'Last Action: 03/30/2026 - Public Hearing Completed (H)... Next House Hearing: Hearing not scheduled... Calendar: Bill currently not on a House calendar.' The 2026 regular session closed with zero data-center legislation enacted (St. Louis Public Radio, Jun. 29, 2026: 'Missouri lawmakers passed 100 bills during the 2026 session, but none of them was about data centers'). Sponsors/House Future Caucus have said they intend to reintroduce similar legislation in the 2027 session; a planned Sept. 16, 2026 House Special Committee public hearing on data centers was CANCELED (announced by Rep. Byrnes on Facebook, reported Aug. 11, 2026) in favor of an advocacy rally at the Capitol the same day, which coincides with the annual veto session. SB4 itself (mo-sb4-2025) remains the only enacted MO statute governing large-load/data-center cost allocation as of this maintenance pass; no amendment to it was found.

• Data center hearing canceled; Rally at Capitol takes its place journalism two-reviewer

  “A Missouri House of Representatives committee public hearing on data center regulation in September has been canceled. Instead, the organizer of the hearing, Rep. Tricia Byrnes, R-Wentzville, is urging people to attend a rally at the Capitol on the same day. Byrnes, the chair of the Intergovernmental Affairs Committee, announced the hearing in late June after House Speaker Jon Patterson, R-Lee's Summit, gave it his approval. The hearing was scheduled for Sept. 16, the same day as the fall veto session. ... Byrnes made the announcement Sunday on Facebook that the hearing would be canceled so as not to compete with the rally happening concurrently. ... The rally in the Capitol rotunda is sponsored by No MO Dirty Data Centers and the Missouri Rural Crisis Center ... The rally is scheduled for 1 p.m. Sept. 16 in the Capitol rotunda.”

  Jefferson City News Tribune, byline Jack Wardynski. MOST RECENT legislative-track development found in this maintenance pass (published just before the 8/16-8/19 collection window). The Sept. 16, 2026 House Special Committee data-center hearing announced in late June (see next source) has been called off; a Capitol-rotunda rally replaces it the same day as the annual veto session. Watch for outcome on next MO maintenance tick.

• Missouri lawmakers pledge new push for data center, AI guardrails in 2027 journalism two-reviewer

  “state lawmakers who have spent months studying it say they'll again push for more guardrails in the next legislative session ... Rep. Collin Willenkamp, the Caucus Chair, said legislation he introduced last year, the AI Infrastructure, Grid Integrity and Water Resources Protection Act, came too late in last year's session to get traction and would return again in 2027. ... When lawmakers return to Jefferson City next month for the annual veto session on Sept. 16, they will be met by opponents of hyper-scale data centers who plan to rally inside the Capitol Rotunda.”

  Spectrum News 1 St. Louis, byline Gregg Palermo, published 3:19 PM CT Aug. 11, 2026 (same day as the News Tribune hearing-cancellation story; the two stories corroborate each other on the Sept. 16 veto-session/rally timing). Reports on a House Future Caucus press conference at Lindenwood University confirming HB 3362 (mo-hb3362-2026) will be reintroduced in 2027, plus a new voluntary local-government 'guidance' document for communities weighing data center proposals (not itself a instrument/tariff/statute, recorded here as context). Also notes St. Charles County's recent six-month data-center moratorium in unincorporated areas -- a new local instrument outside this tick's bounded scope (the 4 flagged conflicts + the 4 tracked instruments); flagged for a future MO facilities/local-ordinance tick, not collected here.

• Missouri lawmakers passed nothing on data centers this year, that could change journalism two-reviewer

  “The legislation, which Wellenkamp and Rep. Mike Costlow, R-Dardenne Prairie, first introduced in February, would have required large-load customers, including data centers, to pay for the costs to provide electricity to those centers. That would include grid infrastructure upgrades. It also contained a permit requirement from the Department of Natural Resources for large water users. ... Despite a warm reception in committee, the bill didn’t move forward. “We had tremendous testimony, almost exclusively in support of. I think we had one testimony opposed, and then I polled the committee afterwards, and it had universal support,” Wellenkamp said. The bill never came up for a vote.”

  MO GATE 2026-08-20: D7 (VA D5 class): the instrument summary asserted the cost-responsibility requirement, the grid-infrastructure inclusion, the DNR large-water-user permit, the co-sponsorship and the 'warm reception / no vote' outcome with NO quote anywhere in the MO corpus supporting any of them.
