Diesel Particulate Filters (DPF) Class

The Air Resources Board (ARB) Training and Compliance Assistance Branch invites you to participate in a new Diesel Particulate Filter (DPF) class. 

Course #511: Diesel particulate filter technology is in the forefront of California’s Diesel Risk Reduction Program. DPF has been verified by ARB to effectively reduce diesel emissions from diesel-fueled internal combustion engines by at least 85%. This course discusses diesel particulate matter and their health effects; DPF theory, operation, construction, and application; as well as regulations requiring particulate filters. Topics include: diesel oxidation catalysts, continually regenerating traps, ammonia slip, selective catalyst reduction/continually regenerating traps, in addition to passive, active, online and offline regenerating strategies.

The Diesel Particulate Filters (DPFs) are a mandatory retrofit device that is required for Heavy Duty Diesel Fueled engines. DPFs are high maintenance and expensive retrofit devices that CARB is requiring for all Heavy Duty Diesel Fueled Engines.
The cost for the retrofit is estimated to be approximately $10,000 for the device itself. The cost of maintenance appeard high for this high maintenance device. Part of the enforcement will apparently be a check to see that the device has been maintained in accordance with guidelines issued by CARB.
This device will cause a substantial increase in the costs for all operators of devices with Heavy Duty Diesel Fueled engines. The added costs will probably force many small operators out of business.
According to estimates by The State of California, approximately half of the Trucks operated in The State of California are operated by the owners of small Trucking Companies.
The small Trucking companies are least able financially to handle the added costs and many will be forced out of business.
In addition there is another mandatory retrofit device called a Selective Catalytic Reduction System (SCR). Estimated cost of that device is also approximately $10,000.
The SCR is also a high maintenance device. 
The SCR operates by injecting a solution of UREA into the Deisel Engine as it operates.
The Urea breaks down in the engine to release Ammonia. In theory the Ammonia reacts with Nitrogen Oxides produced by the engine, reducing the Nitrogen Oxides to Nitrogen.
In the process more particulate matter is created which is supposed to be filtered out of the exhaust by the DPF.  
The result of the new CARB Regulations will be a large number of small operators forced out of business because of the dramaticlly increased costs of operation.
That will result in a severe truck shortage in the near future for the transportation in goods and services in The State of California.
Transportaion of highly perishable products such  as fresh fruit and vegatables will be severly limited. This will have a severe negative impact on the farming industry in The State of California.
Many farms will not be able to get highly perishable fruit and vegatables to market in a timely manner.
This will result in the spoilage of large amounts of fruit and vegetables and large monetary losses to farms in The State of California.
The likely result is that many small family farms will also be forced out of business as a result of the financial losses.
