Counted by distinct business name from the business address on the state list (3 license entries). Contractors often serve areas beyond their home base, so also check the full Illinois list. We don’t show an EPA zone here because the state list gives a city, not a county, and we only show zones we can match to EPA’s county data. Source: Illinois Emergency Management Agency (IEMA-OHS).
