Off-Road Diesel Training Classes

MS504: Regulation for In-Use Off-Road Diesel-Fueled Fleets

The Regulation for In-Use Off-Road Diesel-Fueled Fleets (Off-Road Regulation) requires fleet owners to report to CARB and label their off-road vehicles now, and then requires fleets to reduce the emissions from their older equipment beginning in 2014. This course provides detailed information to help fleet owners understand and comply with the Off-Road Regulation.

New Programs and Regulations at CARB

MS555: New Programs and Regulations at CARB
The California Air Resources Board (CARB) has several new regulatory programs that will help the State become carbon neutral in the future. These programs are going through the public process designed to get input from people and industries affected by the eventual requirements. The class will cover the requirements of existing regulations and then the new programs that will eventually be in effect. The goals for this class are to cover the proposed program elements and elicit participation in the regulatory process. These regulations are needed to meet federal and state ambient air quality standards as well as mandated timelines for reaching carbon neutrality in California.
