We are writing to inform you that the new IL General NPDES Industrial Storm Water Permit (ILR00) was recently passed by the IEPA and went into effect on April 5, 2017. Permittees have been given 180 days from this date to comply with new permit requirements. There are significant changes in this permit from the previous version. Changes include new inspections, new storm water sampling requirements, and regular SWPPP (Storm Water Pollution Prevention Plan) updates based on sampling results. Facilities will now be required to submit storm water samples to a lab for analysis.
