corrected. <br /> On December 26, 1996, 1 conducted a routine hazardous waste inspection at Valley <br /> Industries. Fred Baumbach was the representative from Valley Industries who <br /> accompanied me during the inspection. During the inspection I noted that a waste <br /> stream referred to as "wheelabrator waste" was previously managed as a hazardous <br /> waste, but was currently being managed as a nonhazardous waste, scrap metal. I <br /> asked Mr. Baumbach why this waste was no longer being managed as a hazardous <br /> waste. He explained their metal recycler told him they could handle this waste <br /> stream. I noted the management of the wheelabrator waste as a violation and <br /> documented it as with several other violations of the California Health and Safety <br /> Code, and Title 22, California Code of Regulation, on the Notice to Comply issued to <br /> Baumbach, on December 26, 1996 . <br /> On December 27, 1996, 1 faxed Baumbach sections 25143.10, 25160 (b) (3) and <br /> 25244.19 of the California Health and Safety Code. I also included the phone <br /> numbers of where he could call to get copies of Title 22, and the California Health <br /> and Safety Code. <br /> On January 6, 1996, 1 faxed to Baumbach, section 66262.42 of Title 22, CCR. <br /> On March 6, 1997, 1 received a Certification of Return to Compliance for the <br /> violations noted on the notice to comply issued to Valley Industries on December 26, <br /> 1996. A letter was attached to the certification statement explaining what was done, <br /> or was planned to be done to correct the violations. <br /> On March 25, 1997, 1 sent a memo to Baumbach identifying the corrections that <br /> needed to be made regarding the December 26, 1996, notice to comply. I did not <br /> receive a response to this memo. <br /> On November 14, 1997, Kasey Foley and I conducted a routine hazardous waste <br /> inspection at Valley Industries. During the inspection I followed up on the items <br /> noted on the memo I sent to Baumbach on March 25, 1997. When I asked <br /> Baumbach about the analysis of the waste stream referred to as "wheelabrator <br /> waste", he gave me analytical results for Total Threshold Limit Concentration (TTLC), <br /> of three waste streams that were analyzed on June 18, 1997. The results showed <br /> that the waste stream referred to as "polishing bag house fines" exceeded the TTLC <br /> of 2500mg/kg value for copper. <br /> Baumbach also gave me a copy of analytical results for two other waste streams <br /> referred to as "FAB Center Bag House Fines", and "Wheelabrator Bag House Fines". <br /> The analysis showed that the results were within the Soluble Threshold Limit <br /> Concentration (STLC), and the TTLC. Further analytical testing was required to <br /> determine if these wastes were hazardous wastes. Baumbach also gave me a copy <br /> 4 <br />
