H.B. No. 4690 amends the Occupations Code to enhance motor fuel measuring, quality, and testing standards in Texas. Key changes include the requirement for the commission to set minimum quality standards for motor fuel based on the most recent petroleum standards from ASTM International at the time of sale. The bill also mandates that the department or its representatives follow specific standards and procedures for collecting and testing motor fuel, ensuring compliance with the newly established quality standards. Additionally, the bill introduces a new section that outlines exceptions to these quality standards, particularly regarding gasoline blended with ethanol and seasonal volatility specifications.

The legislation repeals Section 2310.202 and makes several amendments to existing sections, including updating the language to reflect the latest standards and procedures. It specifies that the applicable standard for motor fuel testing must align with ASTM International's most recently adopted or amended standards. The bill also clarifies that violations committed before the effective date of the Act will be governed by the previous law. The Act is set to take effect immediately upon receiving a two-thirds vote from both houses or on September 1, 2025, if that threshold is not met.
