The South Coast Air Quality Management District, also using the acronym South Coast (AQMD), formed in 1976, is the air pollution agency responsible for regulating stationary sources of air pollution in the South Coast Air Basin and the Coachella Valley portion of the Salton Sea Air Basin, in Southern California. The separate California Air Resources Board is responsible for regulating mobile sources (e.g. vehicles) in the air basin.

Basin geography

The South Coast AQMD includes all of Orange County; and the non-desert regions of Los Angeles County, San Bernardino County, and Riverside County including the Coachella Valley.

The South Coast Air Basin area encompassed by the South Coast AQMD amounts to about 10,750 square miles (27,850 square kilometres) and is the second most populated area in the United States. This area has a severe problem with smog, and the South Coast AQMD has been a leader in the nation's efforts to reduce air pollution emissions. The main office is located in the city of Diamond Bar.

Operations

South Coast AQMD develops, adopts and implements an Air Quality Management Plan for bringing the area into compliance with the clean air standards established by national and state governmental legislation.

Air quality and permissible air pollutant emission "rules" are promulgated to reduce emissions from various sources, including specific types of equipment, industrial processes, paints, solvents and certain consumer products. Permits are issued to the pertinent industries and businesses to enforce compliance with the air quality and emission rules, and South Coast AQMD staff conducts periodic inspections to ensure such compliance.

South Coast AQMD's rules apply to businesses ranging from large oil refineries and power plants to gasoline (petrol) fueling stations and dry cleaning plants. There are about 30,000 such businesses operating under South Coast AQMD permits. In general, the agency is limited to establishing rules for regulating stationary sources. Emission standards for mobile sources (automobiles, trucks, buses, railroads, airplanes and marine vessels) are established by the U.S. Environmental Protection Agency and the California Air Resources Board.

Air quality monitoring network

South Coast AQMD also operates an extensive network of air quality monitoring stations (about 40 stations) and issues daily air quality forecasts. The forecasts are made available to the public through newspapers, television, radio, its award-winning smartphone application, social media, its website, and a toll-free Smog Update telephone line.

Air quality and air pollution dispersion modeling

The air quality modeling activities of the South Coast AQMD are one of the functions of the Planning, Rule Development and Area Sources section. That section is also responsible for oversight and commenting upon air pollution dispersion modeling [3] studies performed as part of any environmental impact studies that may be reviewed by or requested by South Coast AQMD. The models that may be utilized include: [4]

Indirect source rule

The SCAQMD has authority to regulate stationary sources of air pollution. These include warehouses which induce truck trips, and thus qualify as indirect sources of air pollution. In 2021, the SCAQMD board voted to authorize the Indirect Source Rule, which requires warehouses larger than 100,000 square feet to take steps to cut pollution, fund similar air pollution mitigation projects, or face penalties. The Inland Empire has experienced substantial development of warehouses which serve the e-commerce industry. [5]

The indirect source rule's main program is the Warehouse Actions and Investments to Reduce Emissions (WAIRE). Under WAIRE, affected warehouses must earn WAIRE points to provide incentives to reduce emissions from trucks which serve them. They can earn points by operating electric trucks or other zero-emissions vehicle, installing charging station or solar panels, or paying to install particulate filters at local schools. Warehouse operators that do not earn sufficient points must pay mitigation fees. [6]

On August 2, 2024, the air district board unanimously voted to authorize a new indirect source rule to reduce nitrogen oxide emissions from railyards in the district. The rule would apply to 25 facilities and would require the facility or all facilities operated by the same operator in the state of California to reduce emissions a specified percentage over the projected baseline or demonstrate that through reduced throughput the facility had a reduced Aggregate Emission Factor. [7] The rule builds upon the CARB In-Use Locomotive rule and the Advanced Clean Fleet rule that have yet to be approved by the EPA and thus the rule cannot go into effect until those are approved. The rule is expected to prevent 300 premature deaths and 2100 hospitalizations annually. [8] [9] [10]

Governing board

South Coast AQMD has a Governing Board of 13 members. Ten of the members are county supervisors and city council members. The remaining three are appointed by California state officials. Current members of the Governing Board include: [11]

†South Coast AQMD member to the California Air Resources Board

The representative for Orange County cities is chosen by the 34 members of the Orange County City Selection Committee. [12] Appointment requires both a majority vote of the committee and a majority vote when weighted by population. [13] In November 2015, Republicans blocked reappointment of Santa Ana Mayor Miguel Pulido, a Democrat, to the board, voting to replace him with Republican Lake Forest Councilman Dwight Robinson. [13]

Administration

The chief Executive Officer of the South Coast AQMD reports to the Governing Board. The following departments report to the Executive Officer:

Administrative departments

Operational departments

Funding for South Coast AQMD

South Coast AQMD utilizes a system of evaluation fees, annual operating fees, emission fees, Hearing Board fees, penalties/ settlements and investments that generate around 73% of its revenue. The remaining 27% of its revenue is from federal grants, California Air Resources (CARB) subvention funds, and California Clean Air Act Motor Vehicle fees. [14]

The California Environmental Quality Act is a California statute passed in 1970 and signed in to law by then-governor Ronald Reagan, shortly after the United States federal government passed the National Environmental Policy Act (NEPA), to institute a statewide policy of environmental protection. CEQA does not directly regulate land uses, but instead requires state and local agencies within California to follow a protocol of analysis and public disclosure of environmental impacts of proposed projects and, in a departure from NEPA, adopt all feasible measures to mitigate those impacts. CEQA makes environmental protection a mandatory part of every California state and local (public) agency's decision making process.

Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems. Health problems attributed to air pollution include premature death, cancer, organ failure, infections, behavioral changes, and other diseases. These health effects are not equally distributed across the U.S. population; there are demographic disparities by race, ethnicity, socioeconomic status, and education. Air pollution can derive from natural sources, such as wildfires and volcanoes, or from anthropogenic sources. Anthropogenic air pollution has affected the United States since the beginning of the Industrial Revolution.

<span class="mw-page-title-main">Pollution in California</span> Overview of pollution in the U.S. state of California

Pollution in California relates to the degree of pollution in the air, water, and land of the U.S. state of California. Pollution is defined as the addition of any substance or any form of energy to the environment at a faster rate than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The combination of three main factors is the cause of notable unhealthy levels of air pollution in California: the activities of over 39 million people, a mountainous terrain that traps pollution, and a warm climate that helps form ozone and other pollutants. Eight of the ten cities in the US with the highest year-round concentration of particulate matter between 2013 and 2015 were in California, and seven out of the ten cities in the US with the worst ozone pollution were also in California. Studies show that pollutants prevalent in California are linked to several 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.
