STORMWATER MANAGEMENT PLAN MORRISON QUARRY <br /> REVISION NO.8 1 August 2022 CERTIFICATION NO.COG500320 <br /> 4. CONTROL MEASURES <br /> This section describes stormwater discharge control measures. Table 2 provides a summary of <br /> control measures implemented at each of the facility areas defined in Section 3. <br /> Stormwater discharge control measures include both structural and non-structural.The purpose <br /> of control measures implemented at the facility is to minimize or reduce the discharge of <br /> pollutants in regulated stormwater discharges from the facility. Non-structural control measures <br /> are referred to in the plan as a Best Management Practice (BMP). Structural controls and BMPs <br /> applicable to this facility are described in the following sections. <br /> 4.1 MINIMIZE EXPOSURE <br /> This facility minimizes exposure by storing materials including fuels and equipment in <br /> containers and inside buildings when practical. <br /> 4.2 GOOD HOUSEKEEPING <br /> Good housekeeping practices are intended to maintain overall order and cleanliness, <br /> reduce the contact of potential pollutants with precipitation, and reduce the likelihood <br /> of release of pollutants to runoff waters. The general permit requires general good <br /> housekeeping BMPs and industry sector specific BMPs. Industry sector-specific BMPs are <br /> recommended for vehicles and equipment storage areas, fueling areas, material <br /> storage areas, vehicle and equipment cleaning areas, vehicle and equipment <br /> maintenance areas. Upon review of the recommendations the following BMPs were <br /> selected for implementation at the facility: <br /> • Pick up and dispose of loose materials, scraps, trash; <br /> • Regularly clean or sweep paved areas; <br /> • Minimize and recycle non-usable materials; <br /> • Use waste collection containers for non-regulated wastes; <br /> • Keep outdoor equipment clean; <br /> • Clean up areas of spills or leaks; <br /> • Use dry materials for cleanup of liquids; and <br /> • Properly recycle wastewater. <br /> 17 <br />
