DEQ acknowledges public concern regarding how proposed increases in pollution emitted from Intel might impact health, particularly the health of vulnerable populations such as children and older adults.
There are two regulatory mechanisms that DEQ has for ensuring that Intel's air quality permit is protective of public health. The first regulatory requirement, and the one used for approval of this permit modification, is based on what are called “criteria pollutants," such as particulate matter, sulfur dioxide (SO2), and nitrogen oxides (NO2), as examples. These pollutants are regulated by the U.S. Environmental Protection Agency's New Source Review program.
One component of New Source Review is a requirement that Intel performs an air quality modeling analysis that is intended to protect public health by ensuring federal air quality standards, called National Ambient Air Quality Standards, for the criteria pollutants, will not be exceeded. EPA sets these standards at levels that protect public health, including sensitive populations such as children and older adults. Part of DEQ's review of the permit application is to ensure that these standards are not exceeded when facilities increase emissions.
EPA's process for the establishment and revision of the NAAQS is based on health science, epidemiological studies, and the deliberations of health professionals. DEQ determined the modeling analysis provided by Intel demonstrates that Intel's increased emissions will not cause or contribute to an exceedance of the federal air quality standards.
However, the modeling shows that both NO2 and PM 2.5 emissions may result in levels that get close to the standards. As result, DEQ has added the following conditions to the permit:
A PM2.5 emissions testing program to take place in 2027.
Adding PM2.5 monitoring to the previously proposed NO2 ambient monitoring at the Ronler Acres fence line. Intel will be required to submit a monitoring plan for DEQ's review and approval. For more information about air quality monitoring, please see the “Response to Comments" document above.
The second regulatory requirement is DEQ's Cleaner Air Oregon Program that analyzes a larger number of toxic air contaminants against health-based criteria. DEQ established this program in 2018 to assess the potential health risks posed by emissions of toxic air contaminants from industrial and commercial facilities to nearby communities. The program requires that all facilities – both existing and new – with air quality operating permits in the state perform a risk assessment and be regulated to health-based standards.
Cleaner Air Oregon uses the latest toxicological science to set regulatory thresholds for risk on over 200 toxic air contaminants. DEQ has developed reference values for each toxic air contaminant for determining cancer and noncancer risk to all members of the public, including sensitive and vulnerable populations such as children. DEQ anticipates calling Intel into Cleaner Air Oregon in April of 2025, when Intel will perform a risk assessment as required under the rules of the program.
