Salt Lake City has some of the worst air quality in the US, with the area ranked 7th for poor air quality among large metropolitan areas in 2020. The west side of Salt Lake County is considered to have the valley's worst air quality due to several factors, including interstate highways, industries, rail lines, jet engines, and warehouses. The city's bowl-shaped topography, surrounded by mountain ranges, also traps particulates and smog. The Jordan River was once thought to protect the city's east side from air pollution, but this assumption proved false, and the west side continues to lag behind in terms of environmental buffers. The health impacts of poor air quality are significant, with increased respiratory and cardiovascular issues, and even cases of severe pneumonia, affecting the young, elderly, and those with pre-existing health conditions.

Salt Lake City's air quality is among the worst in the nation
The poor air quality in Salt Lake City is due to a combination of geographical and human factors. The city's location in a valley surrounded by mountain ranges contributes to the accumulation of pollutants, particularly during winter inversions when smog becomes trapped in the valley. In addition, Salt Lake City experiences frequent wildfires, both within the state and in neighbouring states, which significantly reduce air quality as smoke drifts into the city. The high number of vehicles, particularly older gasoline and diesel-powered models, also contributes to the city's poor air quality. About 50% of air pollution in Salt Lake County is attributed to vehicle emissions.
Certain areas within Salt Lake City have been identified as having worse air quality than others. The west side of Salt Lake County, including West Valley City, has been noted for its poor air quality due to the presence of interstate highways, industries, rail lines, and the concentration of warehouses. Additionally, the historical practice of redlining has resulted in the placement of minority populations in these areas, exposing them to higher levels of pollution. The west side also has fewer natural buffers, such as trees, which help filter out particulate matter.
The health impacts of Salt Lake City's poor air quality are significant. Emergency room visits for respiratory issues increased by 40% during pollution episodes in 2014. Fine particulate matter in the air has been linked to increased rates of respiratory and cardiovascular diseases, stroke, cancer, and autoimmune disorders, as well as reduced life expectancy. Individuals with pre-existing respiratory conditions are advised to limit their physical exertion and outdoor activity during periods of high pollution.
To address the air quality issues, Salt Lake City has implemented several measures. Anti-idling ordinances have been passed, with fines imposed on those who idle their vehicles for prolonged periods. The Utah Indoor Clean Air Act, a statewide smoking ban, also helps reduce indoor air pollution. The city is also taking steps to increase the number of trees and develop parks in the west side of the city to improve air quality. Additionally, the Utah Legislature has been working to identify strategies to reduce pollution, including the adoption of cleaner technologies and improved transportation planning.

Interstate highways, industries, rail lines, and jet engines contribute to pollution
Salt Lake City's air pollution has been a long-standing issue, with climate scientist Logan Mitchell attributing the problem to decisions made by Utahns in the 1890s. The west side of Salt Lake County, in particular, has been identified as having poorer air quality compared to other areas. Interstate highways, industries, rail lines, and jet engines are significant contributors to the pollution in this region.
Interstate highways, such as I-15, I-80, and I-215, crisscross and traverse the area, bringing with them a constant flow of vehicular traffic. These highways serve as major transportation arteries, connecting various parts of the city and facilitating the movement of people and goods. However, the sheer volume of vehicles, including heavy-duty diesel trucks and cars, contributes significantly to air pollution through emissions. The expansion of highways, such as the possible widening of Interstate 15, is a concern for residents as it is expected to bring even more pollution to their communities.
Industries and warehouses located in the west side of Salt Lake City also play a role in the region's poor air quality. These industrial facilities, some of which are required to have permits from the state due to their emissions, release pollutants directly into the air. Additionally, the operations associated with these industries and warehouses, such as transportation and the use of diesel vehicles, further contribute to indirect pollution. The concentration of these polluting sources in the west side of the city exacerbates the issue, impacting the health and quality of life of residents.
Rail lines are another factor in the pollution equation. Trains, particularly those running on diesel, emit pollutants that contribute to the poor air quality in the area. The combination of rail lines and the concentration of warehouses in the region results in a significant number of diesel-powered trains and trucks operating in Salt Lake City, particularly on the west side.
Lastly, jet engines from planes flying into and out of the Salt Lake City International Airport contribute to the air pollution. The revving jet engines release emissions that become more concentrated during stagnant events, such as inversion, affecting the air quality in the surrounding areas.
While efforts are being made to improve air quality, such as adding more trees to the west-side canopy, the impact of these measures may take time to be fully realized. The historical decisions that led to the concentration of polluting sources in the west side of Salt Lake City continue to affect the health and well-being of residents, highlighting the need for long-term solutions that address the root causes of the problem.

The west side has worse air quality due to systemic placement of minority populations
Salt Lake City has been ranked among the top 10 worst places for short-term air pollution in the United States, with the air quality reaching dangerous and even deadly levels. The west side of Salt Lake County, in particular, has been identified as having significantly worse air quality than the east side. This disparity can be attributed to a combination of historical factors and systemic inequalities that have contributed to the concentration of pollutants in certain areas.
One of the primary reasons for the west side's poor air quality is the placement of industries and highways in the area. Interstate highways run through and past the west side, and the region is home to numerous industries, rail lines, and warehouses. Additionally, the jet engines at Salt Lake City International Airport contribute to the air pollution in this area. The concentration of these pollution sources is partly due to a historical mistake made in the 1890s. Experts assumed that the Jordan River would act as a natural barrier, carrying away the smoke and pollution from factories located west of the river. As a result, the west side was left without a natural buffer against air pollution, leading to a buildup of pollutants.
However, another critical factor that cannot be ignored is the impact of redlining. For more than a century, minority populations were systematically placed on the west side of Salt Lake County, around these polluting sources. Redlining, made illegal in 1968, refers to the practice of concentrating minority groups in specific areas, often near sources of environmental hazards. In Salt Lake City, the aftereffects of this discriminatory practice linger, as the west side continues to have a higher proportion of minority residents. According to 2020 census data, while Utah's population is 75% white, about 56% of West Valley City's residents are members of ethnicities other than white, with 39% being Hispanic.
The disparity in vegetation between the east and west sides of Salt Lake County further exacerbates the air quality issue. The east side, typically home to wealthier communities, has older, larger trees and established regional parks, creating a more extensive urban canopy. In contrast, the west side has more built spaces and less vegetation to help filter out particulate matter. This disparity in green spaces is directly linked to income and race, with wealthier and predominantly white communities having easier access to natural buffers against air pollution.
The consequences of this unequal distribution of pollution are severe, with west-siders experiencing a range of negative health impacts. During pollution episodes, emergency room respiratory-related visits in Salt Lake City have increased significantly, and about 200 Utahans are hospitalized with severe pneumonia due to particulate pollution each year. The poor air quality also puts the health of millions of people in the region at risk, especially those under 18 or over 65 and individuals with pre-existing health conditions.

Wildfires from California and other states can drastically reduce air quality
Salt Lake City has historically struggled with poor air quality, with the west side of the city experiencing worse pollution than the east side. This is due to several factors, including the interstate highways, industries, rail lines, jet engines at the airport, and warehouses that are located on the west side. Redlining, the systemic placement of minority populations near polluting sources, has also contributed to the disproportionate pollution on the west side.
Wildfires from California and other states, such as Oregon, Arizona, Nevada, Idaho, and Washington, can drastically reduce air quality in Salt Lake City. The smoke from these wildfires can travel long distances and affect cities as far as Salt Lake City. The particulate matter in wildfire smoke, known as PM2.5, can have significant health impacts, including increased blood pressure, inflammation, and rates of heart attacks and strokes. During August 2020, smoke from California fires caused PM2.5 levels in Cache County, Utah, to exceed 90 mg m−3, more than double the federal threshold.
In recent years, Salt Lake City's air quality has shown some improvement, with a decrease in the number of unhealthy air days. However, data from 2019 to 2021 shows a worrying increase in PM2.5 levels, with the city's air quality exceeding the World Health Organization's annual limits on 37% of days during that period. This trend is attributed in part to wildfires, which are expected to increase in frequency and intensity due to climate change.
To address the air quality issues in Salt Lake City, various measures have been implemented, including anti-idling ordinances, restrictions on burning wood fires, and incentives for cleaner technologies and better transportation planning. The city is also taking steps to increase the number of trees and develop regional parks on the west side, which can help mitigate the pollution.
While Salt Lake City has made some progress in improving its air quality, the impact of wildfires from California and other states remains a significant concern. The city continues to be vulnerable to the effects of wildfire smoke, which can quickly deteriorate air quality and pose serious health risks to its residents.

Salt Lake City has anti-idling ordinances to reduce vehicle emissions
Salt Lake City has gained a notorious reputation for its poor air quality, with the Salt Lake City-Provo-Orem area ranked as the 9th worst city for ozone air quality in the United States. The city's unique topography, with its mountainous landscape, tends to cause pollutants to build up near the surface, especially during inversions. This, combined with emissions from gasoline and diesel vehicles, wood fires, industry, and agriculture, has led to a significant air quality crisis.
To tackle this issue, Salt Lake City has implemented anti-idling ordinances aimed at reducing vehicle emissions. In 2011, the city passed an Idle Free Ordinance, prohibiting unnecessary vehicle idling for more than two minutes within city limits. This ordinance was the result of a proposal from Mayor Ralph Becker, and it received unanimous approval from the Salt Lake City Council. The ordinance is enforceable on both public and private property open to the public, such as drive-through windows and parking lots.
The anti-idling regulations in Salt Lake City are among the strictest in the nation, with fines ranging from $50 to $210 for violations. The city has also implemented a public awareness campaign and provided a six-month grace period to educate residents and visitors about the new law before issuing any fines. These efforts to reduce idling are crucial as vehicle exhaust accounts for over 50% of air pollution in Utah during a typical winter day.
The Idle Free Ordinance in Salt Lake City is part of a broader strategy to improve air quality in the region. Other initiatives include encouraging carpooling and the use of public transportation, promoting the use of newer and clean fuel vehicles, and reducing the use of gas-powered equipment and materials with high volatile organic compound emissions. Additionally, the city is working to add 1,000 trees to the west-side canopy annually and develop a regional park in Glendale to enhance air quality further.
While the anti-idling ordinances in Salt Lake City have resulted in few citations, they have successfully raised awareness and changed social norms around idling. The city's efforts to reduce vehicle emissions are a crucial step towards improving the health and well-being of its residents, especially children and vulnerable populations.
