In California, a gross polluter is a vehicle that emits a disproportionate and significant amount of air pollution. These vehicles are typically those with disconnected emission control equipment or poor maintenance. California has strict new car emission standards and a smog check programme, which means that most cars produce very little pollution. However, a small percentage of automobiles are responsible for a large amount of the state's air pollution. California's air is the most polluted in the nation, and automobiles are the largest source of that pollution. To tackle this issue, new technologies such as remote sensing are being used to identify gross polluters, allowing law enforcement to stop and inspect these vehicles and promote the development of incentives for repairs.

California's air pollution
California has some of the worst air quality in the United States. The state's air pollution is caused by a combination of human activity, mountainous terrain, and a warm climate. The activities of over 39 million people contribute to the pollution, and the mountains trap the pollution, preventing it from dispersing. The warm climate also contributes to the formation of ozone and other pollutants.
The state's air pollution has been a long-standing issue, with the first instances of smog occurring in 1943. In response to the severe air pollution, the Mulford-Carrell Air Resources Act was created in 1967, establishing the California Air Resources Board (CARB). CARB sets health-based ambient air quality standards to protect the public from unsafe levels of outdoor pollutants. They have established standards for eight "traditional pollutants," such as ozone and particulate matter, and identify other pollutants as toxic air contaminants (TACs).
Despite these efforts, air pollution in California continues to harm people's health and the environment. Studies have linked pollutants in California to various health issues, including asthma, lung cancer, birth complications, and premature death. In 2016, Bakersfield, California, recorded the highest level of airborne pollutants of any city in the United States.
The San Joaquin Valley, a region known for its oil, agriculture, and warehouse distribution, has been out of compliance with Environmental Protection Agency standards for 25 years. Residents and activists have criticized the lack of significant progress in improving air quality in the region, attributing it to the influence of polluting industries on policy-making.
To address these concerns, environmentalists and lawmakers are working to strengthen air quality regulations and reduce the impact of dirty air on the health and well-being of Californians. Assembly Bill 2550 aims to empower CARB further and involve community groups in strategizing new ways to combat air pollution.

Stringent new car emission standards
California has long struggled with air pollution. In the mid-20th century, the state's rapid economic growth after the Great Depression was accompanied by a significant increase in air pollution. As a result, smog started to form in the valleys of Southern California, causing respiratory issues for humans and damaging crops.
Dutch chemist Arie Jan Haagen-Smit identified the pollutants responsible for the smog as carbon monoxide, hydrocarbons, and nitrogen oxides emitted from cars and factories through inefficient fuel combustion. In response, the California Air Resources Board (CARB) was established in 1967 with Haagen-Smit as its first chairman. CARB set stringent vehicle emission standards to combat air pollution in the state.
California's vehicle emission standards are the most stringent in the nation. The state has the authority to enforce these stricter standards due to a waiver granted by the Environmental Protection Agency (EPA) under Section 209 of the Clean Air Act (CAA). This waiver allows California to implement its own emission standards for new motor vehicles, provided they are at least as stringent as federal standards.
The state's efforts to reduce vehicle emissions have been supported by new technologies such as remote sensing, which can identify high-emitting vehicles on the road. This enables law enforcement to stop and inspect these vehicles, promoting the repair of gross polluters. Additionally, California has approved rules to phase out the sale of new fossil fuel-powered vehicles, including lawn mowers, large trucks, and diesel-powered trains.
However, California's stringent emission standards have faced legal challenges. In 2019, the Trump administration revoked the state's ability to enforce its own standards, but this decision was later reversed by the Biden administration. More recently, there have been attempts by other states, led by Ohio, to block California's authority, arguing that it violates the U.S. Constitution and federal government authority. Despite these challenges, California continues to lead the nation in setting rigorous vehicle emission standards to improve air quality and protect public health.

Vehicle inspection
In California, a gross polluter vehicle is one that significantly contributes to air pollution. These are typically vehicles with disconnected emission control equipment or those that are poorly maintained. California has stringent new car emission standards and a vehicle inspection programme (smog check) to ensure that most cars produce very little pollution.
The California Health and Safety Code defines gross polluter standards to identify and designate such vehicles. During an initial inspection, if a vehicle's emissions levels exceed the ASM 5015 and ASM 2525 gross polluter standards for HC, CO, or NO, it is deemed a gross polluter. The Bureau of Automotive Repair (BAR) may adjust the emission standards by 30% or apply specific tolerances for HC, CO, and NO if test data indicates the need for changes.
The California Environmental Protection Agency, along with the state board and the department, undertakes a pilot demonstration programme to determine the effectiveness of alternative loaded mode emission tests compared to the IM240 test in reducing emissions. This programme also aims to quantify the additional emission reductions achievable from a remote sensing-based programme that identifies gross polluting vehicles and requires their immediate repair and retest.
The California Highway Patrol assists in conducting roadside auditing, which includes stopping vehicles, traffic management, and issuing notices of non-compliance to gross polluters. When the ownership of a non-compliant vehicle is transferred, the new owner is responsible for bringing the vehicle into compliance and may be subject to an administrative fee.

Remote sensing
California has the most stringent new car emission standards in the nation, and while most cars produce very little pollution, a small percentage of automobiles, or gross polluters, cause a disproportionate amount of air pollution. These vehicles are typically older cars or heavy-duty diesel trucks that lack modern emission control technologies and exhibit signs of neglect, such as visible smoke during acceleration.
In addition to remote sensing, other methods to identify gross polluters include onboard diagnostics, visual inspections, emission testing at designated facilities, and data analytics. Onboard diagnostic systems can reveal malfunctions in a vehicle's emission control system, while visual inspections can spot modifications that may lead to increased emissions. Emission testing at designated facilities ensures compliance with regulations, and data analytics helps assess vehicle emission patterns over time.
Through the use of remote sensing and other detection methods, California can effectively target and mitigate gross polluters. This enables the implementation of solutions to improve air quality, such as providing financial incentives for repairing or scrapping high-emitting vehicles and offering incentives for electric vehicle adoption. By addressing gross polluter vehicles, California can reduce air pollution, mitigate health risks, and work towards a cleaner and healthier future.

Gross polluter vehicle standards
California has strict vehicle emission standards, and a small percentage of automobiles cause a significant amount of the state's air pollution. These "gross polluters" are vehicles with disconnected emission control equipment or poor maintenance. New technologies such as remote sensing can identify these vehicles, enabling authorities to stop, inspect, and cite them.
The Gross Polluter Vehicle Standards are used to identify and designate a vehicle as a gross polluter. During an initial inspection before any repairs, if a vehicle's emissions levels exceed the ASM 5015 and ASM 2525 gross polluter standards for HC, CO, or NO, it is deemed a gross polluter. The Bureau of Automotive Repair (BAR) may adjust the emission standards by 30% or apply specific tolerances if test data indicates the need for changes.
The California Environmental Protection Agency, the state board, and the department work together with the Environmental Protection Agency to implement a pilot demonstration program. This program aims to determine the emission reduction effectiveness of alternative loaded mode emission tests compared to the IM240 test. It also quantifies the achievable emission reductions from a remote sensing-based program that identifies gross polluters and requires their immediate repair and retest.
Owners of gross polluter vehicles face consequences such as citations and fines. They are required to make necessary repairs to their vehicles to bring them into compliance with emission standards. The administrative fee associated with non-compliance may be waived if the vehicle is brought into compliance before transferring ownership.
