The California Air Resources Board has issued a Product Alert for Fuel Additives under the Alternative Diesel Fuels (ADF) Regulation.
The California Air Resources Board (CARB) has conducted emissions testing that showed that tested additives failed to effectively mitigate to the regulatory standard. These results raise significant questions both as to the specific additives addressed by the testing and regarding how best to ensure appropriate performance of additives and formulations generally under the ADF regulation going forward. Accordingly, CARB intends soon to propose modifications to the ADF regulation that will ensure that additives perform consistently with all regulatory requirements.
