Environmental Management Assistance Program (EMAP)’s Post

On February 7, 2024, the U.S. Environmental Protection Agency (EPA) introduced a final rule that tightens the National Ambient Air Quality Standards (NAAQS) for fine particle pollution, also known as PM2.5 or soot. EPA is setting a new benchmark for the annual PM2.5 standard at 9.0 micrograms per cubic meter (μg/m3) based on the latest scientific findings regarding the health effects associated with particle pollution. In simple terms, fine particles (PM2.5), measuring 2.5 micrometers or less in diameter, can come from various sources such as vehicles, smokestacks, fires, and reactions in the atmosphere from power plants and engines. Additionally, there are larger particles (PM10), with diameters ranging from 2.5 to 10 micrometers, originating from road dust, construction, industrial processes, and more. EPA’s analysis of particle pollution involves research on air pollution controls, considering the cost, emissions changes, and other impacts. However, it’s important to note that the EPA recognizes certain limitations and uncertainties in their findings. For instance, EPA faces challenges in accounting for regional or local variations in capital and annual cost components like energy, labor, or materials. Control efficiency estimates assume perfect installation and maintenance, not accounting for potential discrepancies in individual applications. The use of a uniform value for each control may lead to operational disparities, and reflecting the scale of control application variability for small area sources of emissions proves difficult. As air quality standards evolve, there may be changes that impact your small operations. We recommend staying tuned for updates and, if needed, consider reaching out to the Environmental Management Assistance Program (EMAP) for guidance on navigating these changes. At EMAP, we are committed to supporting small businesses in Pennsylvania through changes in environmental regulations and air quality issues.
