Effluent limits and exceedances

EPA’s single-event violation file, as loaded, holds no violation for NPDES IL0066362.

Velarion’s copy of EPA’s ICIS-NPDES files does not include the inspections, formal enforcement actions and informal enforcement actions files, so this page shows none of them. EPA’s free Detailed Facility Report on ECHO lists this permit’s inspections, enforcement actions and penalties.
