What does it do?

SB1147 directs Texas to leave the Interstate Mining Compact and sets a notice-based timetable for ending its Texas offices and statutory framework. As soon as practicable after the act takes effect, the governor must give written withdrawal notice to every other member state’s governor and publish withdrawal notice in the Texas Register. The act does not replace those notices with the legislative vote itself. Final law, section 1.

There are two distinct timing rules. Compact Article VIII says withdrawal takes effect one year after the governor gives written notice to the governors of all other member states, and preserves liabilities already incurred or chargeable before withdrawal. Separately, SB1147 abolishes Texas’s compact-commissioner office and the Texas Mining Council and repeals Natural Resources Code chapter 132 on the first anniversary of the governor’s Texas Register notice. Those clocks depend on different notice events; the bill does not assign them a fixed calendar date. Compact text, Article VIII; Final law, section 2.

The act itself became effective immediately when signed May 13, 2025, after passing by the required votes. That date should not be presented as the date the council was abolished or all withdrawal steps were completed. This explanation describes the statutory timetable; it does not establish the actual dates on which the governor delivered or published the notices. Official history; Final law, section 3 and passage certificates.

What changed along the way?

The introduced, Senate committee, engrossed, House committee and enrolled operative text match. Both committees reported the bill without amendments, and the official floor-amendment index lists none. The enacted law therefore retains the original withdrawal, notice and delayed-repeal structure; there is no substantive committee or floor change to describe. All versions; Introduced text; Amendment index; History; Final law.

Chapter 132 previously enacted the compact and provided for an 11-member Texas Mining Council to advise the governor, who served as Texas’s compact commissioner. The compact supported interstate studies, recommendations and information-sharing about mining, conservation, restoration and industry efficiency. SB1147 removes Texas from that framework on the specified timetable. It does not repeal Texas’s other mining or pollution-control laws; compact Article IX already stated that the compact did not supersede other state laws. Prior adoption statute; Compact text, Articles IV–V and IX; Council duties; Council membership; Final law.

Who could benefit—and who could bear the costs?

Leaving the compact ends Texas’s participation in this particular formal interstate mechanism and eliminates its Texas commissioner office and advisory council when the statutory conditions are met. It may reduce related administrative or membership expenses, but also ends that channel for shared studies and recommendations. The act does not itself quantify an economic or environmental benefit, excuse liabilities preserved by the compact, or abolish the Railroad Commission. Final law; Compact text.

The March 18 fiscal note anticipates no significant state fiscal implication and assumes any savings would be insignificant. It anticipates no local-government fiscal implication and gives no dollar amount for savings. That is a forecast, not evidence that withdrawal produces large savings or has already completed.
