The CARB / ARB (California Air Resource Board) approved Truck and Bus Regulation has had recent rollbacks in the 2014 amendments due to litigation. Sensationalist headlines and misrepresentation of this lawsuit in the media caused many small fleet owners and truck drivers to mistakenly assume this lawsuit brought an end to all CARB diesel regulations.
WRONG. What it actually did was lift the small fleet provisions that attempted to lessen the burden of conversion – which means new compliance regulations now apply. DES Vice President Peter Tuckerman wrote about it on LinkedIn earlier this year. Read the full article here.
Which Vehicles are Affected by the Truck and Bus Regulation?
Individuals, private companies and Federal agencies that own diesel vehicles with a Gross Vehicle Weight Rating (GVWR) greater than 14,000 lbs. that operate in California. This regulation also applies to school buses – but these have different compliance and reporting requirements. State and local government vehicle and public transit buses are already subject to their own regulations. Vehicles that are exempt from other heavy duty diesel regulations – such as Cargo Handling Equipment, Drayage Trucks and Solid Waste Collection Vehicles – may be subject to the Truck and Bus Regulation. Compliance requirements vary based on engine model year and GVWR, each having their own set regulations and conversion schedules.

DES and CARB
DES sells EPA certified or CARB / ARB verified DPF systems and our installation crews are factory trained and DES is a CARB-approved installation company – which translates into our retrofits carrying the highest warranty in the industry. Many other installation companies don’t fully understand that there are strict guidelines for not only the equipment but for the installation – failing to meet these can cause a product to lose its CARB verification.
DES is a CARB-approved installer.

DES doesn’t JUST do retrofitting.
DES is leading the way in diesel emissions reductions in California, Utah, Idaho, Washington, Oregon, Nevada, Canada, and across the west coast. Since 2006, DES has partnered with CARB and many manufacturers to apply the latest diesel aftertreatment technology. DES experts regularly lecture on emissions cleaning and retrofitting solutions and have installed numerous experimental DPF systems under CARB / ARB evaluations. DES conducts regular training of fleets to keep them up-to-date on industry standards and innovations.
With 4 west coast locations and mobile on-site DPF installation teams, DES can quickly and effectively upgrade your emissions systems.
DES doesn’t JUST clean DPFs.
DES has developed a rigorous 8-step DPF cleaning process and have manufactured the industry’s only DPF Oven – the Filtertherm®. The Filtertherm® DPF Thermal Oven is the industry leader in DPF baking technology, and is the perfect compliment to an existing DPF cleaning system. The Filtertherm® is NOT a pottery kiln. It’s a thermal oven specifically designed and built for durability and performance in cleaning Diesel Particulate Filters.
When DES cleans your DPFs, you know they’re cleaned right every time because they clean each filter with the same process, period. Consistency is KING.
