# EPA Renews Texas Higher-Sulfur Diesel Waiver Through Dec. 3

> EPA Administrator Lee Zeldin's November 10 letter renews an emergency waiver effective November 14 through December 3. It temporarily lifts the 15 ppm federal ultra-low sulfur diesel standard and Texas' TXLED requirement, allowing diesel up to 500 ppm sulfur for certain older engines.

## Why it matters

The waiver widens the legal diesel supply in Texas during an extreme fuel shortage, which may ease local tightness. The effect on wider diesel prices is likely limited because it covers only a single state and a short window.
