Inspection Report <br />and documentation or certification of return to compliance, as specified in each required <br />corrective action in the SOV, must be submitted to DTSC via certified mail, return <br />receipt requested, postmarked no later than 60 days from the date of the transmittal <br />letter accompanying this report. <br />VI. CONCLUSIONS <br />LC is an electroplating facility, and electroplating facilities typically generate large quantities of <br />RCRA waste. However, LC is a Conditionally Exempt Small Quantity Generator (CESQG). This <br />appears to be due to LC's use of "continuous flow" rinsing, where rinse water (i.e., industrial water) <br />enters the facility as fast as waste water is discharged from the facility. The continuous flow of rinse <br />water assures that hazardous constituents (e.g., chrome VI, and other metals) never reach or exceed <br />regulatory levels. Because waste rinse waters and waste residues from treatment of rinse waters <br />typically represent the majority of hazardous wastes generated by electroplating facilities, LC appears <br />to generate much less hazardous waste than other electroplating facilities. Even though the <br />continuous flow rinse system may result in an excessively high -rate of water use by the LC facility, <br />according to the local CUPA, LC is operating in compliance with city and county water -use <br />requirements. <br />While LC is a CESQG because LC does not generate any waste rinse waters or residues from <br />waste water treatment, LC nonetheless generates other wastes characteristic of metal finishing <br />operations, including sludges from process tanks, spilled plating bath chemicals including copper - <br />cyanide plating solution, and waste chrome polishing dust. These wastes must be managed safely to <br />protect human health and the environment. In general, the LC facility was not managing these <br />wastes adequately on the date of this inspection. In particular, the LC facility was allowing significant <br />quantities of spilled plating solutions and chrome polishing dust to accumulate on the concrete floor <br />of the facility. The spilled plating solutions are being allowed to remain on the floor for extensive <br />periods of time judging from the corrosion of the concrete floor. According to Mr. Mason, the floor of <br />the facility is not lined with any sort of barrier or impermeable coating to prevent migration of the <br />chemicals through the floor and into the surrounding soil. The circumstances significantly increase <br />the risk for release of hazardous chemicals to the soil under the facility. The spilled chrome polishing <br />dust may pose a threat to the safety of workers in the facility. <br />In addition to the more serious issues related to spilled plating bath chemicals and chrome <br />polishing dust, available documentation (i.e., this inspection report and the previous CUPA inspection <br />report contained in attachment 2) suggests that LC is a chronic and recalcitrant violator of hazardous <br />waste container management regulations. Specifically, LC has continuously failed to adequately <br />label containers holding hazardous waste, LC has failed to keep hazardous waste containers closed <br />except when adding or removing waste, and LC has failed to inspect containers holding hazardous <br />waste weekly to ensure the containers are not leaking. <br />In order to address the problems and issues raised during this inspection, it is suggested that <br />LC implement the following: Although spilled hazardous chemicals should be cleaned -up <br />immediately after they are spilled, LC should implement a routine maintenance schedule that <br />includes cleaning spilled chemicals from the plating room floor. LC should provide training for all LC <br />staff involved with hazardous waste management. Training should include facility -specific topics <br />such as responding to spills, facility maintenance, container management and labeling, and <br />documenting container inspections. It is also suggested that LC send staff involved with hazardous <br />waste management to California Compliance School for hazardous waste generators. California <br />Compliance School is provided at many locations throughout the State of California, and is an <br />excellent source of general information regarding California's hazardous waste management <br />requirements.
