DRAFT <br />QBR=s main warehouse building. Core calipers are sorted and stored by part <br />number in the Caliper Core Storage Yard (see Figure 1), located in QBR=s <br />Manufacturing Yard. The inspected and sorted calipers are stored in covered racks <br />in storage bins (i.e., 55 -gallon metal drums staged horizontally in the storage racks) <br />until scheduled for assembly and packaging. <br />The remaining manufacturing, packaging and storage activities for processing of the <br />core and new calipers are conducted inside QBR=s main manufacturing and <br />warehousing building, where there will be no direct or indirect exposure to <br />stormwater or surface drainage. New caliper components typically go directly to the <br />caliper assembly area, where the units are assembled, air tested, packaged and <br />stored as finished product. <br />Core caliper units are first dis-assembled and drained of residual brake fluids. The <br />recovered caliper components are washed in the Caliper Division=s water-based <br />Parts Washer. The washwater from the Caliper Parts Washer is stored in 55 -gallon <br />drums inside the main manufacturing warehouse and managed as a RCRA <br />hazardous wastes <br />The cleaned caliper housings are bead -blasted, using metal shot, inspected then <br />treated with a rust inhibitor. The surface of the smaller caliper components are <br />prepared for painting by a rotary tumbler and/or by bead blasting using garnet media. <br />The cleaned and treated caliper components typically go to the caliper assembly <br />area, where the units are assembled, air tested, packaged and stored as finished <br />product. <br />1.5.2: Materials and Waste Management <br />A description of the chemical materials used at QBR, and regulated wastes <br />generated by QBR, is provided in the facility=s Hazardous Materials Management <br />Plan and Inventory (see Section 5: Appendisces). Incoming chemical materials are <br />stored either inside the main manufacturing building or are stored in the <br />Manufacturing Yard undercover, on a bermed concrete pad equipped with <br />secondary containment. <br />The type of wastes generated at QBR include the following: <br />C:\TEMP\SMPREV2.doc Section 1-12 <br />
