Ll <br />1 � l <br />11 <br />AT & S was identified as a hazardous wste generator in 1987, producing 140.31 tons of hazardous <br />waste. There have been no previous contact with this facility. <br />V. GENERAL DESCRIPTION OF FACILITY: <br />The AT & S, Diamond & E. Worth site, conducts train repairs, truck maintenance, freight car loading <br />and classification. AT & S is a 15 acre site and the facility employs 75 people. <br />Water is used to clean the train engines and is pumped into box cars and shipped to AT&S facility <br />in Barstow where it is put into an oil/water separator. In 1988 and 1989, contaminated soil from <br />underground tank removals was hauled under manifest to Casmalia (a Class -I Landfill). <br />VI. HAZARDOUS WASTE ACTIVITY DESCRIPTION: <br />A. The bulk of hazardous waste generated at this site is waste water derived from train engine <br />cleaning. In the past, waste water from the service rack area was pumped into a sump (an <br />underground tank box car) on site. The facility at the time of inspection was preparing the <br />closure plan to remove the box tank car. <br />B. From 1988 to 1989, contaminated soil was manifested off site to Casmalia Landfill. This was <br />a one time generation of hazardous waste soil from tank removals (104.75 cubic yards). <br />VII. OBSERVATIONS: <br />Kasey Foley and I arrived at AT & S at 1000 hours. Upon arriving, we met with Dave Irwin, the Site <br />Manager. We identified ourselves and explained the nature of our business. Dave Irwin explained <br />he was taking over the duties of Mac Stahlheber (former Environmental Affairs Manager for this site) <br />Mr. Irwin showed us material safety data sheets and various hazardous waste manifests for <br />contaminated soil and waste water. Mr. Irwin then escorted Kasey and myself to the engine cleaning <br />area where the large diesel engines are washed with water. This waste water is contained in a large <br />sump (12,000 gallons) where it is pumped to a waiting box car and shipped to Barstow to be <br />separated. Several unlabeled 55 gallon drums where observed to contained product oil. Mr. Irwin <br />explained that they no longer change engine oil on this site, however, the oil changes previously <br />performed on the site were for the large "piggy back' lifts and incoming/outgoing semi -trucks storing <br />loads for trains. These oil changes are contracted out to a company called Interminal Services, 1001 <br />S. "B" Street, Stockton, CA. Interminal Services works on site and transports recycled oil to All <br />American Oil, P.O. Box 625, Pleasanton CA. <br />Mr. Irwin was unsure of the exact type and amount of hazardous waste generated in 1989. He <br />referred us to Dave Clark (AT&S P.E. Manager, Environmental and Hazardous Material Control, <br />5770 S. Eastern Avenue, Los Angeles, CA. 90040) for more information regarding hazardous waste <br />generation at the Diamond & E. Worth (AT&S) site. I contacted Dave Clark by phone several times <br />regarding hazardous waste generation information (manifest, amounts of waste, types of waste). On <br />May 20, 1990, PHS-EHD received hazardous waste manifests for contaminated soil, waste oil, and <br />waste oil/water generated from 1987 to 1990. <br />2 <br />
