The state air board reported this week that they do not have their heavy-duty diesel truck electronic reporting tool ready so they are going to extend the reporting period to March 30, 2012. Reports can now be filed electronically at http://www.arb.ca.gov/msprog/onrdiesel/reportinginfo.htm.  All diesel trucks that have been signed up with the agency as agricultural or "AG" trucks, and are staying under specific mileage thresholds, must report their 2011 mileage to ARB by the March 30, 2012 deadline.  Besides the "AG" provision, the ARB diesel truck regulation has other special provisions that lengthen some or all of the compliance requirements. Also if dairymen or others have trucks not covered under the Ag exemption (because they exceed the mileage thresholds, did not report, etc.) there are other exemptions that require reporting also.  An example would be the small fleet exemption that delays retrofit requirements for fleets with three or fewer trucks.  Those fleets may also have to report this month depending on the age of their trucks. Information is available on the ARB’s diesel hotline 866-634-3735 or by contacting your local WUD field representative. The ARB offers several programs that provide grants, loans and loan guarantees, vouchers or rebates to help truck and equipment owners with the purchase of cleaner trucks and equipment.
