Introduction
Air quality significantly impacts public health and the environment. In the United States, nearly 46% of the population—approximately 156 million people—live in areas with unhealthy levels of air pollution, as reported in the American Lung Association’s 2025 “State of the Air” report. (lung.org)
Understanding local air quality standards and knowing how to monitor and report violations are crucial steps toward improving air quality in your community.
Local Air Quality Standards
National Ambient Air Quality Standards (NAAQS)
The Environmental Protection Agency (EPA) sets NAAQS to protect public health and the environment. These standards specify acceptable concentrations of pollutants in the air. In February 2024, the EPA revised the annual standard for fine particulate matter (PM₂.₅) from 12 to 9 micrograms per cubic meter (µg/m³), acknowledging that the previous standard did not sufficiently protect human health.

State and Local Regulations
States and localities may implement stricter air quality standards based on regional needs. For instance, New Mexico has recently tightened regulations on ozone-precursor pollutants and methane emissions as part of its climate and clean air policy initiatives. (apnews.com)
Monitoring Air Quality
Air Quality Monitoring Stations
Air quality monitoring stations measure pollutant levels in the atmosphere. However, a significant number of Americans lack access to local air quality data. In 2024, over 50 million people lived in counties without any air quality monitoring stations. (news-medical.net)
Personal Air Quality Monitors
Individuals can use personal air quality monitors to assess pollution levels in their immediate surroundings. These devices can provide real-time data and help identify pollution sources.
Reporting Air Quality Violations
Identifying Violations
Violations occur when pollutant levels exceed established standards. Common pollutants include ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.
Reporting Mechanisms
- Local Environmental Agencies: Contact your city’s or state’s environmental protection agency to report violations.
- EPA’s National Response Center: For immediate threats to public health or the environment, call 1-800-424-8802.
- Online Platforms: Some regions offer online portals for reporting air quality issues.
- Location: Specific address or coordinates.
- Date and Time: When the violation was observed.
- Description: Details of the observed pollution, including any visible emissions or odors.
- Evidence: Photos or videos, if possible.
- In 2024, over 50 million Americans lived in counties without air quality monitoring stations.
- The EPA revised the annual PM₂.₅ standard from 12 to 9 µg/m³ in February 2024.
- In 2024, New Mexico imposed a record $47.8 million fine on Targa Resources for excessive air pollution.

Information to Provide
When reporting a violation, include:
Community Involvement
Educating the Public
Raising awareness about air quality standards and monitoring can empower communities to take action. Educational programs and workshops can provide valuable information.
Collaboration with Local Authorities
Engaging with local environmental agencies can lead to collaborative efforts in monitoring and improving air quality. For example, in 2024, New Mexico reached a record $24.5 million settlement with Ameredev over air pollution violations tied to excessive natural gas flaring in the Permian Basin. (apnews.com)
Conclusion
Monitoring and reporting air quality violations are essential for safeguarding public health and the environment. By understanding local air quality standards and actively participating in monitoring efforts, individuals can contribute to cleaner air in their communities.
