Inspection R2= Not applicable. r. Recycling Records: Did not review. s. Other: k 1 6 1 M 1 11 1010 — 6 ; On October 20, 2000, at approximately 0915 hours, Michael Kith of San Joaquin County Environmental Health and Barbara Heinrich, Robert Brushia and I representing the Department of Toxic Substances Control (Department) arrived at the Stockton Unified School District, Corporation yard (SUED). We were met by the receptionist. I asked to speak to either the Plant Manager or Environmental Coordinator. The receptionist went to get Mr. Steve Breakfield the Facilities Planner. We introduced ourselves to Mr. Breakfield and I explained to Mr. Breakfield the purpose of our inspection. I asked for Mr. Breakfield's permission to conduct the facility inspection, review records, and take photographs. Permission was granted by Mr. Breakfield. Mr. Breakfield said that he would call Mr. Butch Schmidt and Mr. Roy Knight to join us in the inspection because they were the ones familiar with hazardous waste management throughout the facility. Mr Knight and Mr. Schmidt showed up shortly. Mr. Breakfield handed the inspection over to Mr. Knight and Mr. Schmidt. We sat down in the conference room and I explained that the Department was the Lead Agency and that Michael Kith with San Joaquin County was participating as an observer. I explained that the inspection would be conducted in two parts: (1) a facility walk through, and (2) a document review. SUED is the corporation yard for the school district. Their main function is maintaining the school buses for the district. Parts washers are maintained by Safety Kleen. Waste antifreeze, used oil, and used oil filters are generated at the site. They also have a paint booth where they generate paint waste and spent solvent. They also generate some waste PCB ballasts. Each school site that generates hazardous waste has its own EPA Identification Number. Asbestos from floor tiles and asbestos covered boiler pipes are occasionally generated. After an overview of what goes on at the site and the hazardous waste generated, we proceeded with the facility walk through. We began our walk through outside the Lube Room area. On the west side of the Lube Room we observed one open container of crushed used oil filters that was unlabeled. On the north side of the Lube Room we observed three unlabeled containers. Mr. Schmidt identified the containers as two used transmission fluid containers and one waste antifreeze container. I explained to Mr. Schmidt and Mr. Knight that hazardous waste containers must be kept closed and the requirement for proper hazardous waste labeling on each container. In the same area we observed one used oil convault tank approximately 500 gallons without the start date of accumulation or the words, "Used Oil - Hazardous Waste" on the tank. We also observed approximately 40 used lead/acid batteries without the date when the used lead/acid battery was taken out of service. None of the batteries appeared to be broken, missing caps, or leaking acid. I let Mr. Knight and Mr Schmidt know that lead/acid batteries may be accumulated for up to a period of one year, provided you do not accumulate more than a ton of used lead/acid batteries at one time. We observed the steam cleaning rack for engines located east of the Lube Room. Mr. Schmidt stated that the city didn't have a problem with the water being discharged to the Publicly Owned Treatment Works. The steam cleaning rack has an oil/water separator. I explained to Mr. Knight and Mr. Schmidt that the oil/water separator is a treatment unit. I informed Mr. Knight and Mr. Schmidt that they need to make a waste determination on the steam cleaning liquid waste before it goes to the separator for treatment. If the waste liquid is a hazardous waste, a permit will be required for the treatment of the liquid waste. Mr. Schmidt stated that Evergreen picks up the sludge from the steam cleaning rack and the bus wash rack located near the fuel facility. Mr. Schmidt stated that the bus wash area recycles the water they use. We worked our way to the paint storage area. I observed a garbage bin that appeared to have empty one gallon paint cans along with an aerosol container that did not feel as though the can was completely empty. I informed Mr. Schmidt that non -empty aerosol containers that held hazardous materials that are no longer useable shall be managed as hazardous waste. I asked Mr. Schmidt to talk to the painters and submit to me their protocol for handling inoperable non -empty aerosol containers. Inside the paint storage building which is installed with secondary containment, I observed two open, not properly labeled DTSC (3/95) Page 3 of 16-
