The American Thoracic Society opposes the EPA’s final rule on Data Transparency issued in the waning days of the Trump Administration. The final rule, which is the focus of a press conference today, is a continuation of the Trump Administration’s persistent attack on the science showing the adverse health effects of environmental pollution. This rule would exclude vital scientific data from future EPA decision-making and make patient confidential information more vulnerable to public disclosure.
• Exposure to higher amounts of fine particulate air pollution was associated with a greater likelihood of having chronic kidney disease.
• This link was stronger in urban areas, males, younger adults, and adults without comorbid diseases.
Since 2014, the University of Utah has maintained research-grade suites of air quality instruments installed on light rail trains. These mobile sensors cover the same area as 30 stationary sensors, providing the Salt Lake Valley with a highly cost-effective way to monitor its greenhouse emissions and fill in gaps in emissions estimates.

The American Thoracic Society is extremely concerned with today’s announcement about changes in how the EPA evaluates the costs and benefits of environmental policy. While the details of economic analysis of environmental regulations are complex, the guiding principle is remarkably simple: compare all the costs and benefits of agency actions. The proposed changes in how costs and benefits are evaluated will sufficiently degrade the credibility of economic analysis conducted at the EPA to the point that it is no longer able to function as an objective policy analysis tool.
Salt Lake County, Utah’s air pollution is at times the worst in the United States. Underserved neighborhoods—and their schools—experience the highest concentrations. A new study utilized nearly 200 PM 2.5 sensors through the Air Quality and U network and revealed persistent social inequalities in Salt Lake County schools.
