The general NPDES permit NPDES No. ILG84 for non-coal mines can cover operations that mine or process: construction sand and gravel, crushed stone or industrial sand. The mine owner or operator must submit a permit application or Notice of Intent (NOI) to the Illinois EPA prior to initiating mining activities to obtain coverage under the general NPDES permit.
After the Illinois EPA reviews the permit application or notice of intent and determines that the mining operation could be covered by the general NPDES permit, a notice will be posted on the Illinois EPA's webpage that the mining operation may be covered by the general NPDES permit for non-coal mines 30 days after the posting date. Coverage under the general NPDES permit will be by letter issued by Illinois EPA.
Interested parties may contact the Illinois EPA, Bureau of Water, Permit Section at (217) 782-0610 regarding the mining operations covered by the general permit. Permit application or facility information may be obtained by request in accordance with the IEPA's FOIA rules.
