Air Quality Regulations:
Truck and Bus Regulation: Diesel Emissions Reduction; 12/12/08
Sierra Club activists joined other environmentalists, environmental justice activists, and public health activists at the Air Resources Board in Sacramento on December 12, 2008 to support strong diesel emission and greenhouse gas reduction regulations to be applied to ”on-road trucks and buses”.
We were successful! Read our letter to the ARB.
“The regulation requires affected trucks and buses to meet performance requirements between 2011 and 2023. By January 1, 2023 all vehicles must have a 2010 model year engine or equivalent.
Affected vehicles include on-road heavy-duty diesel fueled vehicles with a gross vehicle weight rating (GVWR) greater than 14,000 pounds, yard trucks with off-road certified engines, and diesel fueled shuttle vehicles of any GVWR. Out-of-state trucks and buses that operate in California are also subject to the regulation.”

Air Quality Laws:
AB 118: Alternative fuels and vehicle technologies: funding programs.
We thank Assembly Speaker Fabian Núñez for writing the most important, 2007 funding bill for energy and air quality programs. During the 7-year life of this law, about $200 million will be collected annually through motor vehicle-related fees that will benefit three major environmental programs:
- ~$120M for Californian Energy Commission’s “Alternative and Renewable Fuel and Vehicle Technology Program”
- ~$50M for California Air Resources Board’s “Air Quality Improvement Program”
- ~$30M for Bureau of Automotive Repair’s “Enhanced Fleet Modernization Program”(e.g. the voluntary retirement of high-polluting passenger vehicles and light- and medium-duty trucks)
AB 233: the Healthy Heart and Lung Act.
Sierra Club CA co-sponsored this bill (with American Lung Association) in 2007 and we are pleased to report that Governor Schwarzenegger signed the bill into law on Oct. 13, 2007. The author was Assemblymember Dave Jones of Sacramento.
AB 233 addresses the greatest source of toxic emissions in the state – older diesel vehicles — by increasing enforcement of existing regulations. In addition, operators of commercial motor vehicles will be required to clear their citations for violating emissions rules before having their registrations renewed.

AB 1007: Air quality: alternative fuels
The purpose of this 2005 law, authored by noted environmentalist, Assemblywoman Fran Pavley, and sponsored by the Natural Resources Defense Council, is to increase the use of ‘alternative fuels’ in California, thereby making the state less petroleum-dependent. Unlike other air quality laws, this law will be implemented by the State Energy Resources Conservation and Development Commission, though in partnership with the Air Resources Board.
The law states “to develop and adopt a state plan to increase the use of alternative fuels” not later than June 30, 2007.
The plan is available on the Energy Commission’s website.
The Sierra Club position is to ensure that there is accurate life-cycle assessment of fuels, assurances of no deterioration in air quality, and that sustainability standards for biofuels be developed. We will also follow the adoption of the Low Carbon Fuel Standard (a 2007 Governor’s Executive Order incorporated into the plan) closely related to AB 1007. Funding for the implementation of the state alternative fuels plan is expected to come from AB 118. (See below)
By participating in the Clean Air Dialog, a working group of the California Environmental Dialog, Sierra Club will keep abreast of actions taken by the Energy Commission and provide meaningful input.
The Air Quality Committee will collaborate with the Global Warming and Energy Committee as it follows the implementation of the adopted State Alternative Fuels Plan.
“If there ever was a “common sense” clean air bill, this was it. Heretofore, as incredible as this may sound, a vehicle could be emitting visible smoke from its tailpipe during the smog check, yet still pass!! This 2006 bill, sponsored by Assemblywoman Sally Lieber, sponsored by Sierra Club California, the Bay Area Air Quality Management District and the California Council for Environmental and Economic Balance, won bi-partisan support in the state legislature along with the support of health experts at the American Lung Association, air pollution control officers, and automobile and oil companies.
Another important aspect of the bill was to “require the Bureau of Automotive Repair pay an owner of a motor vehicle that has failed its most recent smog check who retires the vehicle at a dismantler, up to $1,500 and authorizes a higher payment if it determines that the payment is cost-effective.”
AB 1229: Nation: Air pollution – new motor vehicles: air pollution label.
This 2005 law took effect January 1, 2009 – it applies to all new vehicles sold in California and will be of great benefit to anyone purchasing a new vehicle who wants to lower BOTH their vehicle’s greenhouse gas and smog-forming emissions.
The law requires that an Environmental Performance (EP) label showing both a ‘global warming’ and a ‘smog’ score is placed on the vehicle.

We thank both former Marin County Assemblyman Joe Nation and the Union of Concerned Scientists for this helpful new law.
AB 2522: Vehicle Registration Fee
We thank Assemblyman Juan Arambula (Fresno) for one of the few air quality laws made in 2008. AB 2522 authorizes the San Joaquin Valley Unified Air Pollution Control District to increase the existing vehicle registration fee from $6 to up to $30 for incentive-based programs to achieve state and federal air quality standards and requires at least $10 million of the revenues to be used to mitigate air pollution in disproportionately impacted communities in the San Joaquin Valley.

AB 2683, Lieber. Air pollution: smog check (2004)
We thank Mountain View Assembly woman Sally Lieber for writing this necessary law in 2004 that ended the ‘thirty-year, rolling exemption’ from smog check for vehicles. As a result of her efforts, all 1976 and newer model vehicles are subject to smog check. Considering that older vehicles are the most polluting because they lack the smog controls found a newer vehicles, this law is undoubtedly keeping our air cleaner.
AB 2683 was sponsored by the Planning and Conservation League, the Bay Area Air Quality Management District, and the California Council for Economic and Environmental Balance. It quickly became a Sierra Club California priority and was included as one of only four bills that volunteers advocated to their legislators during the Sierra Club CA Lobby Day on August 9, 2004.
SB 719: Reform of San Joaquin Valley Unified Air Pollution Control District.
We are delighted to report that this bill, authored by Senator Michael Machado of Stockton, was signed by Governor Schwarzenegger on Oct. 14, 2007. The law adds two city appointees and two experts to the Air District’s governing board, increasing membership to 15, thus providing more representative and qualified leadership to the body that is responsible for air quality in the Central Valley.
