Counts come from EPA's Enforcement and Compliance History Online (ECHO) and cover the last five years for inspections, enforcement actions and penalties, and the last 12 quarters for violations. Most inspections and actions are carried out by state and local agencies, and how often they report to EPA varies by state and program. A formal action or penalty is a record of an enforcement step, not a finding about current conditions at a facility. Facility pages list only active businesses and government facilities with a formal action or penalty; facilities that appear to be private homes or individuals are counted in totals but not listed.
