The air quality in approximately 110 east Texas counties is out of compliance with the federal Clean Air Act’s standard for ground-level ozone. In response, the State of Texas revised its compliance plan to do a number of things including a change in the formulation (physical properties) of diesel fuel offered for sale in those non-attainment counties. The goal of these changes is to reduce NOx emissions and other pollutants from diesel-powered vehicles and non-road equipment. The new low emission diesel fuel is commonly referred to as “TxLED”.
Biodiesel is covered by these new “TxLED” regulations. The executive director of the Texas Commission on Environmental Quality (TCEQ) has determined that blending biodiesel into Texas Low Emission Diesel (TxLED) is not acceptable unless the blend has been approved by TCEQ as being equivalent to TxLED in reducing NOx emissions.
These new fuel property requirements were set to take effect for fuel producers beginning October 1, 2005. However, per a decision made last Friday (9/23/05), that date has been delayed for 30 days due to the impact on refining and distribution infrastructure from the recent hurricanes.
The NBB, industry members, and stakeholders have been engaged in this issue for many months and it is one of the industry’s top regulatory priorities.
