Over the past 20 years, WSTA (Western States Trucking Association) has been advocating on behalf of its members its regulatory concerns to the California Air Resources Board (CARB), local air districts, and EPA staff and Board members during their development of the many rules our members and industry have been subject to. Throughout that time, we have been updating and educating our membership on the progress of the many challenging environmental rules. Recently, our Executive Committee and Board directed your Association to initiate and develop a litigation strategy to stop the unrealistic (Electric Only) Advanced Clean Fleets and Clean Truck Rules.

Here is the list of legal efforts so far:
