“Assessment year” refers to the year for which assessment data were collected.
“Release date” is when results were posted to EPA’s website.
“HAPs included” shows how many of the Clean Air Act’s list of hazardous air pollutants (HAPs) were included in each assessment. Each assessment also includes one additional air toxic, diesel particulate matter, which was assessed for noncancer results only.
