Item #206 HSC 25200.3(c)(6)(7) <br />Hazardous Waste Treatment records attached. <br />The waste water pretreatment system is designed to treat(neutralize) all <br />wastewater as produced. "Storage" is sufficient only to cover short periods of <br />imbalance between production (wash rack) and treatment flows. The cone bottom <br />tank is emptied daily to ensure that all particulates pass through the system to the <br />sewer without collection. Thus, the only residuals will be recovered oil/diesel <br />from the API separator, which are picked up periodically by a registered oil <br />disposal company for disposal. <br />The pretreatment system is fully automated requiring the operator only to start the <br />mixers in the neutralizers (pre and final) and the hose pump feeding the pre - <br />neutralizer. All systems operate automatically to control the p H of the <br />wastewater. The operator checks the p H meters periodically, along with the <br />operation of mixers, pumps, levels, tec. Should the p H move outside the control <br />range requiring system shut down, an alarm sounds to alert the operator. <br />During the operator inspections, the operator also looks for leaks/spills, of <br />wastewater within or outside of the containment, signs of deterioration or stress of <br />tanks, piping, pumps, etc. which could result in leaks/spills. Any leaks or spills <br />must be evaluated as to be a threat to people or the environment and appropriate <br />action imitated. (alarm, notify supervisor, regulatory agencies, etc) <br />Item #207 HSC 25200.3 (c) <br />Inspection records attached <br />Inspection logs are maintained both by the operator and the facility manager. <br />Typically, the operator records are monthly check sheets requiring daily entries <br />(i.e. Wash Rack Maintenance log) and the Facility Manager records are kept in a <br />log which he maintains. Both of these records are maintained daily. <br />Item #3210 HSC25200.C(2) <br />Hazardous Waste cannot be minimized without reducing or eliminating the <br />business activity which produces it (trailer washing). This requirement is not <br />applicable to this operation. <br />
