Counts cover active sites in the Facility Registry Service; inspections, formal actions and penalties cover the last five years, quarters in violation the last three years. The EPA attributes a case that covers several facilities to each of them; area penalty totals here count an amount shared through the same federal case once, facility figures show the amount attributed to that facility.
