What does it do?

SB766 updates old references to the Texas Natural Resource Conservation Commission to the Texas Commission on Environmental Quality, or TCEQ, across many Texas statutes. Its 107 sections mainly correct agency names, definitions and headings in laws involving water, waste, agriculture, local government, natural resources and vehicle emissions. Signed June 20, 2025, it took effect September 1, 2025. Complete enacted law; History.

The act updates the agency-creation section and the wording for its official seal. It also adds an express rule that, effective January 1, 2004, a legal reference to the old commission is a reference to TCEQ. That date is the reference-conversion rule written in this act—not a claim that a brand-new environmental agency began operating in 2025. TCEQ already appeared in existing statutes before SB766. Sections 67 and 69; Prior agency-creation wording; Existing statute already naming TCEQ.

Several details deserve more than a name-change label. The “new aquaculture facility” definition now expressly includes a commercial facility whose owner or operator first sought waste-discharge authorization from TCEQ after December 31, 2003, while retaining the old-agency category after January 19, 1999. The pesticide chapter gains a definition of “commission.” The vehicle-inspection chapter changes its shorthand from “conservation commission” to “environmental commission” and rearranges the department definition; TCEQ and the Department of Public Safety remain distinct agencies. Sections 1, 7 and 58–64; Earlier aquaculture definition; Earlier vehicle definitions.

The act also repeals the levee-district chapter’s old “water commission” definition, while updating its separate “commission” and “executive director” definitions to TCEQ. It does not repeal the levee-district chapter or abolish TCEQ. Sections 101 and 106; Prior definitions, including the repealed one.

What changed along the way?

Every section of the enrolled act was reviewed, and all five operative text versions—introduced, Senate committee, engrossed, House committee and enrolled—match. The Senate issued a corrected committee report, but the available operative text comparison shows no substantive version change. Both committees reported without amendments and the amendment index lists none. Introduced; All versions; Corrected-report and passage history; Amendment index.

Many requirements appear in full because their agency references are being corrected; that does not make the whole reproduced provision new law. For example, the vehicle-emissions provision’s existing penalty ceiling of $500 per violation remains $500: the edit changes the commission’s shorthand, not the amount. The same distinction matters when reading the reproduced water, pollution-control and district-finance provisions. Section 62 and other reference edits; Prior penalty provision.

Who could benefit—and who could bear the costs?

The practical benefit is more consistent identification of the responsible environmental agency, reducing confusion caused by outdated names. The act is not a broad rewrite of emissions limits or a new environmental agency funding program. Its express definition and historical-reference provisions still matter when determining which statute or agency applies. The law does not quantify resulting administrative savings or environmental outcomes. Scope of enacted edits.

Both the March 4 introduced and May 19 engrossed fiscal notes anticipate no significant state or local-government fiscal impact and assume state costs can be absorbed using existing resources. Neither assigns a dollar value to clearer statutory references. Introduced fiscal note; Engrossed fiscal note.
