The EPA recently tightened the air quality standard for fine particulate matter (PM2.5), impacting millions in violation areas. While this stricter standard is beneficial, many states lack crucial data to develop effective control plans.
Test & Tackle: Regularly check air quality and clean thoroughly to remove dust and allergens. Ensure good ventilation by opening windows or using air purifiers.
This data gap stems from funding cuts and dismantled programs, leaving them "flying blind." Additionally, the EPA's focus on local control options overlooks the significant contribution of upwind sources.
States like Texas, particularly border counties and Houston, lack both detailed data and comprehensive studies to address their specific issues. Similar problems exist in various states facing the new standard for the first time.
A narrow focus on local control could lead to less effective and more expensive solutions. A broader approach that considers upwind sources, like ammonia from agriculture and emissions from coal plants, can offer more significant air quality improvements.
Investing in better data collection and implementing broader controls on upwind sources are key to helping states meet the new standard efficiently and save lives. This will require collaboration and a shift towards comprehensive strategies.
