Relating to motor fuel measuring, quality, and testing standards.

SB 2699 sets the minimum quality standards for gasoline and gasoline-ethanol blends sold in Texas to align with the most recent nationally recognized ASTM petroleum standards, including ASTM D4814 for gasoline. It establishes measurement tolerances for fuel dispensers based on NIST Handbook 44 and includes specific exceptions, such as a 1.0 psi vapor pressure waiver for ethanol blends (except in certain counties during May-October) and flexibility for regional volatility adjustments. This affects fuel retailers, distributors, and the Texas Department of Licensing and Regulation, which will enforce compliance through testing and sampling. The bill repeals outdated sections and takes effect on September 1, 2025, unless passed with a two-thirds vote for immediate implementation.
