arbcombo -- Final Rulemaking Packages for On-Road Diesel Vehicles and Off-Road Equipment Regulations Posted: 10 Nov 2011 15:32:47
In October, the Air Resources Board (ARB) filed with the Office of Administrative Law (OAL) final rule-making materials for the following regulations: the In-Use On-Road Diesel Vehicle Regulation (Truck and Bus Regulation), the Greenhouse Gas Emission Reduction Regulation (Tractor-Trailer GHG Regulation), the Off-Road Large Spark Ignition Engine Fleet Requirements (LSI Fleet Regulation) and the Regulation for In-Use Off-Road Diesel Fueled Fleets (Off-Road Regulation). OAL has until December to approve the regulations and file them with the Secretary of State. The rulemaking documents are available for the truck regulations at: http://www.arb.ca.gov/regact/2010/truckbus10/truckbus10.htm, and for the off-road regulations at: http://www.arb.ca.gov/regact/2010/offroadlsi10/offroadlsi10.htm. Background The Air Resources Board adopted a number of regulations that require diesel engine owners to reduce their engine emissions. These regulations are part of the State’s plan to meet federal ambient air quality standards and to protect public health. Between now and 2023, nearly all trucks and buses that operate in California and have a manufacturer’s gross vehicle weight rating greater than 14,000 pounds must upgrade to reduce exhaust emissions. Similar requirements will also become effective in the next several years affecting owners and operators of certain off-road equipment (including equipment used in construction, industrial, and airport operations). To comply with these requirements, fleet owners can upgrade existing engines by installing particulate matter (PM) filter retrofits or other Verified Diesel Emission Control Strategies (VDECS), or by upgrading to cleaner engines. In addition, the California Global Warming Solutions Act of 2006 (AB 32) established requirements to achieve reductions of greenhouse gas (GHG) emissions. AB 32 requires the Air Resources Board (the Board or ARB) and other state agencies to adopt regulations and other requirements that would reduce statewide GHG emission levels to the equivalent of 1990 levels by 2020. The Tractor-Trailer GHG rulemaking is one of 44 early action measures identified by the Board and requires certain tractor and trailer combinations to use low-rolling resistance tires and aerodynamic technology.
