2008 California Statewide Truck And Bus Rule
The California Statewide Truck and Bus Rule was initially adopted in December 2008 by the California Air Resources Board (CARB) and requires all heavy-duty diesel trucks and buses that operate in California to retrofit or replace engines in order to reduce diesel emissions. All privately and federally owned diesel-fueled trucks and buses, and privately and publicly owned school buses with a gross vehicle weight rating (GVWR) greater than 14,000 pounds, are covered by the regulation. Implementation was originally scheduled for January 1, 2011 but recent amendments were considered in December 2010. The rule now requires the installation of particulate matter filters beginning January 1, 2012 and replacement of older engines beginning January 1, 2015. Nearly all applicable vehicles are required to have 2010 model year or the equivalent to 2010 engines by January 1, 2023. Background Diesel exhaust particulate matter (PM) was identified as a toxic air contaminant by the Air Resources ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California Law
The law of California consists of several levels, including Constitutional law, constitutional, Statutory law, statutory, and regulatory law, as well as case law. The California Codes form the general statutory law, and most state agency regulations are available in the California Code of Regulations. Sources of law The California Constitution, Constitution of California is the foremost source of state law. Legislation is enacted within the California Statutes, which in turn have been codified into the 29 California Codes. State agencies promulgate regulations with the California Regulatory Notice Register, which are in turn codified in the California Code of Regulations. California's legal system is based on common law, which is interpreted by case law through the legal opinion, decisions of the Supreme Court of California, California Courts of Appeal, and Appellate Divisions of the Superior Courts of California, and published in the ''California Reports'', ''California Appella ...

Government Of California
The government of California is the governmental structure of the U.S. state of California as established by the California Constitution. California uses the separation of powers system to structure its government. It is composed of three branches: the executive, consisting of the Governor of California and the other constitutionally elected and appointed officers and offices; the legislative, consisting of the California State Legislature, which includes the Assembly and the Senate; and the judicial, consisting of the Supreme Court of California and lower courts. There is also local government, consisting of counties, cities, special districts, and school districts, as well as government entities and offices that operate independently on a constitutional, statutory, or common law basis. The state also allows direct participation of the electorate by initiative, referendum, recall and ratification. Executive branch California's elected executive officers are: File:Gavin Newsom ...

Emission Standard
Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect human life. Different regions and countries have different standards for vehicle emissions. Regulated sources Many emissions standards focus on regulating pollutants released by automobiles (motor cars) and other powered vehicles. Others regulate emissions from industry, power plants, small equipment such as lawn mowers and diesel generators, and other sources of air pollution. The first automobile emissions standards were enacted in 1963 in the United States, mainly as a response to Los Angeles' smog problems. Three years later Japan enacted their first emissions rules, followed between 1970 and 1972 by Canada, Australia, and several Eu ...

Air Basin
An air basin is an area within a ring or partial ring of mountain A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and ...s that in the absence of winds holds air and smog within the area.

Diesel Exhaust
Diesel exhaust is the gaseous exhaust produced by a diesel type of internal combustion engine, plus any contained particulates. Its composition may vary with the fuel type or rate of consumption, or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator or other application. Diesel exhaust is a Group 1 carcinogen, which causes lung cancer and has a positive association with bladder cancer. It contains several substances that are also listed individually as human carcinogens by the IARC. Methods exist to reduce nitrogen oxides (NOx) and particulate matter (PM) in the exhaust. So, while diesel fuel contains slightly more carbon (2.68 kg CO₂/litre) than petrol (2.31 kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower due to higher efficiency. In use, on average, this equates to around 200 g CO₂/km for petrol and 120 g CO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Particulate Filter
A diesel particulate filter (DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.Tom Nash (May 2003) "Diesels: The Smoke is clearing", ''Motor '' Vol.199 No. 5, p. 54, Hearst Business Publishing Inc. Mode of action Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%. Some filters are single-use, intended for disposal and replacement once full of accumulated ash. Others are designed to burn off the accumulated particulate either passively through the use of a catalyst or by active means such as a fuel burner which heats the filter to soot combustion temperatures. This is accomplished by engine programming to run (when the filter is full) in a manner that elevates exhaust temperature, in conjunction with an extra fuel injector in the exhaust stream that injects fuel to react with a catalyst element to burn off accumulat ...

Best Available Control Technology
A State Implementation Plan (SIP) is a United States state plan for complying with the federal Clean Air Act, administered by the Environmental Protection Agency (EPA). The SIP, developed by a state agency and approved by EPA, consists of narrative, rules, technical documentation, and agreements that an individual state will use to control and clean up polluted areas. Lowest achievable emissions rate The Lowest achievable emissions rate (LAER) is used by the EPA to determine if emissions from a new or modified major stationary source are acceptable under SIP guidelines. LAER standards are required when a new stationary source is located in a non-attainment air-quality region. It is the most stringent air pollution standard above the best available control technology and reasonably available control technology standards. Best available control technology Best available control technology (BACT) is a pollution control standard mandated by the Clean Air Act: :..an emission limitation ...

United States Environmental Protection Agency
The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tr ...
