The Pollution Control Agency proposed to reissue the NPDES/State Disposal System MNG-490000 for Construction Sand & Gravel, Rock Quarrying, and Hot Mix Asphalt Production Facilities, which is set to expire September 30, 2011. The permit authorizes stormwater and wastewater discharges. Changes include adding the monitoring of stormwater discharges to surface waters and adding discharges from industrial sand and crushed stone mine and quarry areas to mine dewatering.
