Regulations adopted Friday by The California Air Resources Board (CARB) will require nearly all truck owners that operate in the state to install diesel exhaust filters on their rigs by 2014, replace engines older than the 2010 model year between 2012 and 2022 according to a staggered implementation schedule, and install fuel-efficient tires and aerodynamic devices on their trailers that lower greenhouse gas emissions and improve fuel economy.

The regulations were made available for public comment in October. According to CARB, the state will offer over $1 billion in funding to help meet the standards. This includes Carl Moyer grants, designated for early or surplus compliance with diesel regulations; Proposition 1B funds, for air quality improvements related to goods movement; and AB 118, which establishes a low-cost truck loan program for early compliance with the truck rule.
