Kentucky's Efforts To Reduce Air Pollution

Kentucky is taking steps to address air pollution, which poses serious health risks, including asthma attacks, impaired lung development in children, and even death. With a population of around 4.46 million, the state faces challenges from industrial activities, vehicular emissions, and exportation, which contribute to elevated pollution levels. Notably, the Rubbertown industrial complex in West Louisville has been a particular area of concern, with community groups like REACT advocating for environmental justice and monitoring air quality. However, a recent Kentucky bill, House Bill 137, has been criticized for potentially hindering efforts to combat air pollution by restricting data sources for enforcing airborne contaminant restrictions. Despite these challenges, Kentucky's cities have maintained air quality within the WHO's target rating, showcasing a commitment to improving the air Kentuckians breathe.

Community-led air monitoring groups like REACT are fighting for environmental justice

REACT's work involves community air monitoring to protect neighbourhoods from air pollution, including pollutants coming from the Rubbertown industrial complex, where companies have sent toxic materials airborne for decades. They have used various methods for air sampling, including simple buckets with a vacuum mechanism, PurpleAir monitors, and handheld particulate matter monitors. These methods are relatively low-cost and allow community members to monitor their neighbourhoods for dangers and push for improvements.

However, a proposed House Bill 137 in Kentucky could disqualify these low-cost methods and limit the type of tools available for ensuring safer communities. The bill aims to ensure that only data collection methods, emissions tests, or monitoring methods approved by the U.S. Environmental Protection Agency are used in cases enforced by the Louisville Metro Air Pollution Control District and the Kentucky Energy and Environment Cabinet. While the bill's sponsor, Republican Rep. Jim Gooch Jr., has stated that the goal is to ensure quality data, critics argue that it will make it harder for community groups like REACT to fight air pollution and advocate for environmental justice.

Despite the potential challenges posed by the bill, Eboni Neal Cochran, the leader of REACT, has stated that the group will continue its work and fight for environmental justice. They may have to change their approach, but they remain dedicated to air monitoring and using that data to tell their story. REACT's efforts are crucial in addressing the serious health threats posed by air pollution, which can trigger asthma attacks, harm lung development in children, and even lead to premature deaths and serious illnesses.

House Bill 137 could disqualify low-cost community methods of monitoring air quality

Kentucky is known for its horse racing, bourbon, coal, state and national parks, and its world-famous Kentucky Fried Chicken. The state has about 4.46 million inhabitants, making it the 26th most populous state in the US. While Kentucky has a respectable level of air quality throughout the year, there are certain months with sudden spikes in pollution. The state has to deal with the issue of vehicular emissions, which is a constant problem both in the US and worldwide. Exhaust fumes from cars and other personal vehicles release chemical pollutants and hazardous particulate matter into the air. The use of larger vehicles, such as trucks and lorries, further compounds the issue.

In February 2025, West Louisville advocates expressed concerns about a Kentucky bill that could make it harder to fight air pollution. House Bill 137 could disqualify low-cost community methods of monitoring air quality. The bill would restrict the Louisville Metro Air Pollution Control District and the Kentucky Energy and Environment Cabinet from using certain data sources to enforce restrictions on airborne contaminants. Specifically, it would limit the types of tools that can be used to ensure safer communities. Under the proposed legislation, agencies could base cases only on data collection methods, emissions tests, or monitoring methods approved by the US Environmental Protection Agency (EPA). The bill's sponsor, Republican Rep. Jim Gooch Jr., stated that the goal is to ensure quality data is used because businesses face severe penalties for violating air pollution rules.

However, members of grassroots groups like Rubbertown Emergency ACTion (REACT) in West Louisville oppose House Bill 137. REACT has been fighting to protect West Louisville neighbourhoods from air pollution, including pollutants from the Rubbertown industrial complex. They have been using low-cost community air monitoring methods, such as simple buckets with a vacuum mechanism to collect air samples, PurpleAir monitors, and handheld particulate matter monitors. These methods have helped them determine what pollutants are present in the air and in what concentrations. REACT leader Eboni Neal Cochran stated that House Bill 137 would be detrimental to their work, but they will continue fighting for environmental justice and adapting their methods to meet the new requirements.

Kentucky's bourbon industry and exportation contribute to rising pollution levels

Kentucky is known for its bourbon, with the industry generating $9 billion for the state's economy each year. The state produces 95% of the world's bourbon supply, and the demand for Kentucky bourbon has seen a 465% increase since 2000. The bourbon industry is also a major employer, creating over 23,100 jobs and generating an annual payroll of over $1.63 billion. The industry has also boosted tourism, with over 74% of visitors to the Kentucky Bourbon Trail travelling from out of state.

However, the bourbon industry's rapid growth and high demand have led to increased exportation, which contributes to rising pollution levels in Kentucky. The increased use of vehicles, especially large trucks and lorries, for the transportation of bourbon contributes to vehicular emissions, a significant source of pollution in the state. The large vehicles used for transportation often run on fossil fuels like diesel, emitting larger amounts of pollutants than smaller vehicles.

In addition to vehicular emissions, the bourbon industry itself has an environmental impact. The production process requires energy, and the distilleries release pollutants into the air. While the exact emissions from bourbon production are unclear, the industry's energy consumption and waste generation likely contribute to air pollution.

The state of Kentucky has taken some steps to address air pollution, and despite the presence of polluting sources, all 11 cities in Kentucky met the WHO's target rating for the best quality of air in 2020. However, there were periods in 2020 when the PM2.5 count was considerably higher, indicating that certain months experience sudden spikes in pollution.

While the bourbon industry contributes to rising pollution levels in Kentucky, it is important to note that other factors also play a role. Industrial activities, human-based activities, and coal production are additional sources of pollution in the state.

Vehicular emissions are a constant problem, especially from large vehicles using diesel

Kentucky is known for its horse racing, bourbon, coal, state and national parks, and, of course, Kentucky Fried Chicken. With a population of around 4.46 million people, it is the 26th most populous state in the US. While Kentucky has a respectable level of air quality year-round, there are still issues with pollution that need to be addressed. Vehicular emissions are a constant problem, and this is especially true for large vehicles that use diesel.

Cars and other personal vehicles are a major contributor to air pollution in Kentucky, as they release exhaust fumes that contain various chemical pollutants and hazardous particulate matter. The situation is exacerbated by the presence of large vehicles such as trucks and lorries, which are necessary for the state's import and export industry. These larger vehicles often run on diesel and, due to their size and weight, can emit much higher levels of pollution than smaller cars.

Diesel-powered vehicles produce a range of pollutants, including nitrogen oxides (NOx), particulate matter (PM), volatile organic compounds (VOCs), and toxic air contaminants. NOx emissions contribute to the formation of ground-level ozone, which is a major component of smog and has harmful effects on human health. PM2.5, which refers to particulate matter less than 2.5 micrometres in diameter, is of particular concern as it can penetrate deep into the respiratory system and cause serious health issues.

To combat vehicular emissions, Kentucky can implement a range of strategies. Encouraging the use of electric or hybrid vehicles, improving public transportation to reduce the number of cars on the road, and enforcing stricter emissions standards for diesel vehicles can all help to reduce pollution levels. Additionally, regular maintenance and emissions testing for diesel vehicles can ensure that they are operating as cleanly as possible.

Kentucky can also invest in technologies to mitigate the impact of diesel emissions. This includes the use of diesel particulate filters, which can capture and reduce the amount of PM2.5 released into the atmosphere. Selective catalytic reduction systems can also be employed to lower NOx emissions by injecting a reducing agent into the exhaust stream, converting NOx into harmless nitrogen gas and water vapour.

While vehicular emissions, especially from diesel-powered large vehicles, remain a challenge for Kentucky, a combination of policy measures, technological advancements, and behavioural changes can help the state make significant strides in improving air quality and protecting the health of its citizens.

Particle pollution from wildfires can cause serious illnesses and even premature death

Kentucky is known for its horse racing, bourbon, coal, state and national parks, and Kentucky Fried Chicken. With its prominence in bourbon production and exportation, as well as its industrial factors and human-based activities, Kentucky faces challenges in maintaining good air quality. Vehicular emissions, for instance, are a constant problem, with cars, trucks, and lorries contributing to air pollution through their exhaust fumes and the use of fossil fuels like diesel.

While Kentucky has shown a respectable level of year-round air quality, with all of its cities meeting the WHO's target rating for the best quality of air as of 2020, there are still concerns about air pollution, particularly in Louisville. Louisville experienced its highest pollution readings at the end of 2020, coinciding with the start of winter.

Community groups like Rubbertown Emergency ACTion (REACT) in West Louisville have been actively fighting to protect their neighborhoods from air pollution, including pollutants from the Rubbertown industrial complex. REACT conducts community air monitoring and advocates for environmental justice. However, proposed legislation like House Bill 137 could potentially hinder their efforts by limiting the types of data sources that can be used to enforce restrictions on airborne contaminants.

In the context of Kentucky's efforts to combat air pollution, it is important to understand the impact of particle pollution from wildfires, which can have serious health consequences. Wildfire smoke is a mixture of gaseous pollutants, hazardous air pollutants (HAPs), water vapor, and particle pollution. Particle pollution, or particulate matter (PM), refers to a mixture of solid and liquid droplets suspended in the air, with sizes ranging from micrometers to those only visible under an electron microscope. Fine particles (PM2.5), with diameters of 2.5 micrometers or less, are of particular concern and make up approximately 90% of the total particle mass in wildfire smoke.

The health effects of particle pollution from wildfires can vary in severity. Exposure to particle pollution can cause eye and respiratory tract irritation, exacerbation of asthma, and heart failure. Fine particles act as respiratory irritants, leading to persistent coughing, phlegm, wheezing, and difficulty breathing. Even healthy individuals can experience transient reductions in lung function and pulmonary inflammation. Particle pollution may also impair the body's ability to remove inhaled foreign materials, such as viruses and bacteria, from the lungs. In more severe cases, particle pollution has been linked to triggering asthma attacks, heart attacks, strokes, and even premature death. Studies have shown that children in California who breathed smoky air during wildfires experienced increased coughing, wheezing, bronchitis, colds, and hospital visits for respiratory issues. Additionally, wildfire smoke can contain carbon monoxide (CO), which reduces oxygen delivery to the body's organs and tissues, leading to headaches, nausea, dizziness, and potentially death at high concentrations.
