Mississippi's Fight Against Air Pollution: Strategies And Initiatives

Mississippi has been taking steps to improve its air quality and reduce air pollution, which has been a persistent issue in the state. According to the American Lung Association's 2024 State of the Air report, Jackson, the state's capital, ranked as the 29th worst city in the nation for air pollution for the second year in a row. However, there are signs of improvement, as the city received a failing grade in the 2024 report, while it ranked 118th worst in the previous year. Mississippi is working to address this issue through various measures, including the implementation of the Clean Air Act and the Mississippi Air and Water Pollution Control Act, which aim to control, prevent, and abate air pollution. The state is also taking steps to improve indoor air quality, which can be as dangerous as outdoor pollution, by encouraging the use of air purifiers and fresh air machines. Additionally, Mississippi is providing real-time air quality data and notifications to help residents make informed decisions about their health and wellbeing.

The Mississippi Department of Environmental Quality's Air Division is working to improve air quality

The Air Division provides several resources to the public to help improve air quality. For instance, the Air Notice Distribution Webpage offers notifications on Air Division notices and air-related updates. Additionally, the Environmental Permits Division provides information on air permits and related application forms, while the Environmental Compliance and Enforcement Division addresses air compliance and enforcement issues.

The Air Division also proposes and implements rules and regulations to reduce air pollution. For example, they have proposed rules affecting new and existing crude oil and gas facilities, as well as infrastructure for new HAP additions. Furthermore, they have implemented the Clean Air Mississippi Project and the Diesel Emission Reduction Grant Program to actively work towards cleaner air.

The Air Division also provides an Air Quality Forecast and monitors air quality through initiatives like the Cherokee Air Quality Monitoring. They encourage the use of the "AQI Air Quality App" to help individuals track the air pollution levels in their area and take necessary precautions.

Overall, the Mississippi Department of Environmental Quality's Air Division is actively working to improve air quality in the state by enforcing regulations, providing resources and information to the public, implementing initiatives and projects, and encouraging individuals to take an active role in monitoring and improving air quality.

The Clean Air Act is being enforced to reduce air pollution

The Clean Air Act (CAA) is a comprehensive federal law that regulates air emissions from stationary and mobile sources. The Act authorises the Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) to protect public health and the environment. The EPA also regulates common air pollutants, including nitrogen oxides (NOx), sulfur dioxide (SO2), particulate matter (PM10 and PM2.5), carbon monoxide (CO), volatile organic compounds (VOCs), ozone (O3), and lead (Pb).

In Mississippi, the Clean Air Act is enforced by the Mississippi Department of Environmental Quality and EPA Region 4. The state has developed State Implementation Plans (SIPs) to achieve the NAAQS, which include emission reduction strategies. These strategies aim to reduce air pollution and protect public health and welfare.

One of the goals of the Clean Air Act is to address the health and welfare risks posed by certain widespread air pollutants. The 1977 amendments to the Act set more rigorous requirements for reducing emissions in areas that do not meet the NAAQS, and established the Prevention of Significant Deterioration (PSD) regulations for areas that already meet the standards. The PSD regulations aim to prevent any significant deterioration in air quality above an established baseline level.

The Clean Air Act also requires the EPA to establish emission standards for "major sources" and "area sources" of hazardous air pollutants. "Major sources" are stationary sources that emit or have the potential to emit 10 tons or more of a hazardous air pollutant per year. These emission standards are known as "maximum achievable control technology" or "MACT" standards. The EPA is required to review and revise these standards as necessary to address any residual risk.

By enforcing the Clean Air Act, Mississippi is taking important steps to reduce air pollution, protect public health, and improve the environment. The Act's regulations, standards, and implementation plans provide a comprehensive framework for reducing air pollution and its negative impacts on communities.

The EPA is proposing stricter limits on ozone pollution

I could not find specific information on how Mississippi is reducing air pollution. However, I can provide information on the EPA's proposal to impose stricter limits on ozone pollution.

The Environmental Protection Agency (EPA) is proposing stricter limits on ozone pollution, also known as smog, which is formed when air pollution from cars, power plants, and other sources mixes with sunlight. The EPA's Clean Air Scientific Advisory Committee and the White House Environmental Justice Advisory Council have urged the agency to lower the current standard of 70 parts per billion, as scientific evidence suggests that the current level is inadequate to protect public health and welfare.

The EPA's scientific advisory panel has recommended a limit of 55 to 60 parts per billion, stating that this range is more likely to be protective and provide an adequate margin of safety. However, the EPA Administrator, Michael Regan, has decided to delay the implementation of new ozone pollution standards until after the 2024 election, citing the need for additional evaluation and review. This decision has been met with disappointment from public health advocates and Democratic lawmakers, who argue that inaction threatens public health, especially for those with underlying conditions such as asthma or lung disease.

The EPA's delay marks the second time in 12 years that a Democratic administration has postponed new ozone standards before an election year. The current standard was reaffirmed in December 2020 under the Trump administration and has not been changed since 2015. The EPA plans to gather more information through workshops in the spring of 2024 and release a review plan for action by the end of the year, with a final decision potentially years away.

Individuals are encouraged to use public transport or carpool

The state of Mississippi is taking steps to improve its air quality and reduce air pollution. One key recommendation is for individuals to use public transportation or carpool when travelling. This strategy is particularly relevant for office workers, who are encouraged to leave their personal vehicles at home and opt for shared modes of transport. This approach can significantly reduce vehicle emissions, which are a primary source of outdoor air pollution.

Using public transportation or carpooling can lead to a notable decrease in the number of cars on the road, thereby lowering the overall amount of harmful gases released into the atmosphere. This is especially important in urban areas, where a high density of vehicles can contribute to elevated levels of air pollution. By consolidating passenger trips, public transportation and carpooling reduce the total number of vehicles on the road, minimising emissions and improving air quality.

For those who live in close proximity to their destinations, walking or biking are also excellent alternatives to driving alone. These active modes of transportation not only benefit the environment but also promote personal health and well-being. By choosing to walk or bike, individuals can reduce their carbon footprint, improve their cardiovascular fitness, and minimise their exposure to polluted air within vehicles.

To further encourage the use of public transportation and carpooling, individuals can advocate for improved infrastructure and services. This may include lobbying for more frequent and reliable public transportation options, dedicated bike lanes, and carpool incentives such as high-occupancy vehicle (HOV) lanes or reduced toll rates for carpool vehicles. By making these sustainable options more accessible and appealing, more people will be inclined to leave their cars at home, contributing to a collective effort to reduce air pollution in Mississippi.

Additionally, individuals can take proactive steps to reduce their overall contribution to air pollution. This includes limiting their personal fossil fuel consumption, participating in local energy conservation programs, and monitoring local air quality through websites like AirNow.gov. By staying informed and making conscious choices, individuals can play a crucial role in improving air quality and protecting their health, as well as the health of their communities and the environment.

The Air Compliance Dashboard provides data on environmental compliance

The Air Compliance Dashboard is a useful tool for anyone looking to understand the state of Mississippi's air quality and the actions taken to improve it. The dashboard provides an easy-to-use summary of environmental compliance and enforcement activities, offering answers to important questions that impact the state's air quality.

For instance, users can learn about the facilities that are regulated, how many have been inspected or evaluated, and how many have alleged violations and have been subject to enforcement. This information is crucial for holding businesses and organizations accountable for their impact on the environment and public health.

The dashboard is part of a broader effort by Mississippi to address air pollution and protect its citizens. The state's Department of Environmental Quality has an Air Division specifically tasked with ensuring that air quality is protective of public health and welfare. This division works to control, prevent, and reduce air pollution to comply with various regulations, including the Mississippi Air and Water Pollution Control Act and the federal Clean Air Act.

Additionally, Mississippi residents can take advantage of resources like MyAir, which provides data on various air quality metrics for the state. MyClimate is another useful tool, offering insights into greenhouse gas emissions by sector and other climate data. These platforms, along with the Air Compliance Dashboard, empower citizens with knowledge about their local air quality and the actions needed to improve it.

Mississippi still faces challenges, as evident by Jackson's poor ranking in the American Lung Association's "State of the Air" report. However, with continued efforts from state agencies, individuals, and communities, Mississippi is taking steps towards reducing air pollution and improving the health and well-being of its residents.
