Central Ohio residents breathed easier this year, with air quality improvements highlighted by the Mid-Ohio Regional Planning Commission’s (MORPC) latest End-of-Season Air Quality Report. Covering data from November 2023 through October 2024, the comprehensive analysis reveals promising trends, key changes in air quality standards, and innovative local initiatives aiming for cleaner air and healthier communities.
Major Reduction in Air Quality Alerts
The 2023-24 season saw a significant drop in Air Quality Alerts, with only three issued compared to 11 the previous year. This improvement largely stemmed from reduced wildfire smoke impacts, a relief for many residents sensitive to pollution, such as children, older adults, and individuals with respiratory conditions like asthma.
However, MORPC noted that thin layers of wildfire smoke were still periodically detected, underscoring the ongoing influence of distant fires on local air quality.
Central Ohio Enjoys More Good Air Days, But Challenges Remain
Throughout the ozone season from March to October, 72% of days were categorized as Good on the Air Quality Index (AQI), though this marked a slight decrease of 3% compared to the previous season. Despite this slight dip, the overall trend remains positive, demonstrating consistent efforts and community engagement in managing air quality.
“Our team works diligently to provide timely and accurate air quality information. This report underscores how regional and national factors, such as weather patterns and policy changes, continue to shape our air quality. Together we can ensure a safe and healthy future for our residents as our region grows,” said JR Diaz-Hernandez, MORPC’s Air Quality Coordinator. This year’s report underscores both our progress and the need for continued vigilance, especially during warmer, drier periods.
EPA Tightens Air Quality Standards for Fine Particulates
A significant regulatory change came on February 7, 2024, when the U.S. Environmental Protection Agency (USEPA) tightened the permissible annual average of fine particulate matter (PM2.5) from 12.0 to 9.0 micrograms per cubic meter (µg/m³). This stricter standard reflects increased understanding of the health risks posed by particulate pollution and signals a broader effort to enhance air quality nationwide.
Neighborhood-Level Monitoring Empowers Local Action
In response to evolving standards and the necessity for detailed local data, MORPC has significantly expanded its air monitoring network across Franklin County. Partnering with Franklin County Public Health, MORPC deployed 36 PurpleAir sensors providing real-time air quality readings at the neighborhood level.
“For the 2023-24 season, the majority of days in Central Ohio fell within the Good Air Quality Index (AQI) category; however, we saw a decline compared to the previous season. The data highlights the importance of ongoing monitoring and community action to maintain and improve our region’s air quality,” explained Brandi Whetstone, MORPC’s Director of Sustainability. Real-time monitoring data from these sensors is publicly accessible online at purpleair.com.
Proactive Steps for Better Air Quality
Recognizing the impact of transportation on air quality, MORPC continues its strong advocacy for sustainable travel options through its Air Quality Alert system and specialized programs like the emissions-reducing Gohio Commute. By promoting carpooling, biking, and public transit, MORPC encourages residents to contribute to cleaner air through practical everyday choices.
Staying Informed, Staying Healthy
As MORPC’s latest report highlights, community awareness and proactive measures are critical to sustaining air quality improvements. Residents are encouraged to sign up for MORPC’s Air Quality Alert notifications to stay informed and prepared during poor air quality events.
