The bill amends the Occupations Code to establish updated motor fuel measuring, quality, and testing standards in Texas. It introduces new definitions for "ASTM" (American Society for Testing and Materials) and "NIST" (National Institute of Standards and Technology) and mandates that the Texas Department of Licensing and Regulation follow the latest motor fuel quality testing standards and procedures. The bill also specifies that the tolerances for motor fuel metering devices must align with the most current edition of NIST Handbook 44. Additionally, it sets minimum quality standards for motor fuel based on the latest ASTM petroleum standards and outlines specific exceptions to these standards, particularly regarding gasoline blended with ethanol.

Furthermore, the bill repeals certain existing provisions related to motor fuel quality testing and introduces new sections that detail exceptions for gasoline sold during varying volatility classes and allowances for vapor pressure tolerances. It also allows for the extension of seasonal specifications for vapor pressure to facilitate the distribution of existing fuel stocks. The bill ensures that any violations occurring before its effective date will be governed by the previous law, maintaining legal continuity. The act will take effect immediately upon receiving a two-thirds majority vote or on September 1, 2025, if that threshold is not met.
