One is a central mix plant while the other is a dry batch plant. Ready -mix concrete is produced in an enclosed area in the central mix plant. The dry batch plant depends upon trucks to mix the concrete Ready mix concrete is produced at the site by combining sand, gravel, cement, fly ash, water, and admixtures. Some of the raw materials are stored in stockpiles while other materials are stored in silos to protect them from slormwater runoff. The chemical admixtures are stored in bulk chemical storage tanks. After the ready -mix concrete is produced, the product is removed from the site by truck and distributed to off -site construction projects. Cam fiance Histo The permitteelfacility does not have any prior compliance issues with the NC Division of Water Quality and the following was found in the Charlotte Mecklenburg Storm Water Services (CMSWS) compliance files. On August 16, 2004, CMSWS investigated a discharge into an unnamed tributary of Stewart Creek from Southern Concrete Materials State Street facility. During the investigation, CMSWS personnel observed a gray colored plume entering Stewart Creek from an unnamed tributary of Stewart Creek. There was also a build up of concrete residue on the stream bed of both the tributary and main channel of Stewart Creek. The discharge was identified to be from Southern Concrete Materials. Southern Concrete Materials addressed the discharge by repairing the impacted storm drain system at the site. On November 29. 2007 CMSWS investigated a complaint from the City of Charlotte Street Maintenance group regarding a discharge of concrete slurry to the municipal storm drain system from Southern Concrete Materials State Street facility. No discharge was observed by CMSWS personnel during a site inspection on November 30, 2007. CMSWS personnel noted that the stormwater management practices implemented by Southern Concrete Materials in October 2004 appeared to be working properly. Industrial Operations/City of Charlotte Stormwater Ordinance Review; Central Mix Concrete Plant — Ready mix concrete is produced in a covered area in the central mix plant. The plant consists of overhead aggregate bins, cement and fly ash silos, and conveying and weighing equipment. Fine and coarse aggregates are delivered by trucks, dumped into a drive -over hopper or stockpiled an site. Materials from stockpiles are loaded into the hopper and conveyed to the concrete plant. Cement and fly ash are delivered to the site by railcar and/or tanker trucks and pneumatically pumped into the overhead silos. Admixtures used in the concrete are delivered to the site in tanker trucks and pumped into bulk chemical storage tanks in a covered area. Admixtures are then pumped into the concrete in varying proportions depending upon the mix design requirements. Once the raw materials are fed into the mixer and combined to form ready mix concrete, the final product is removed from the site by truck and distributed to off -site construction projects, Dry Batch Concrete Plant -- The dry batch plant uses the same raw materials as the central mix plant. However, the dry batch plant depends upon the ready mixed concrete trucks to mix the concrete. The admixtures for the dry batch plant are located in an outdoor storage area with secondary containment. The cement, fly ash, sand, stone, water, and admixtures are proportioned by weight and discharged into the concrete trucks for mixing and subsequent delivery. Truck Wash Area — After loading, drivers wash dried products from the trucks in the truck wash area. The truck wash water discharges into a collection basin, which allows the solids to settle. The wash water is recycled for reuse in plant operations.

The stormwater BMPs (storm drain inlet protection, silt fencing in drainage channel, etc.) should also be identified on the site plan. Southern Concrete has installed 18-inch risers around the storm drain inlets at the site to prevent process water from entering the storm sewer system. The area around the risers should be routinely checked and cleaned as needed. Qualitative MOnitorin Yes No NA NE Has the facility conducted its Qualitative Monitoring semi-annually?

The silt fencing appeared to be working effectively to prevent excess concrete residue from entering the tributary to Stewart Creek during storm events. The storm drainage channel and the area in front of the silt fencing should be routinely checked and cleaned as needed. Rage: 5 Michael F. Easley, Govmor e William G.
