Process: In the machine shop, hand tools were used to take apart turbine engines and repair or rebuild them. Parts were ordered and shipped to the facility for rebuilding as necessary. Occasionally parts were spray painted with primer after repair. Concrete floors in the warehouse area were in good condition with no cracks or chips. SECOR observed absorbent pads around the bottom of the parts washer indicating a possible recent spill. Mr. Sam Mingua, Shop Supervisor advised SECOR that the pads are placed to collect possible drippage from the cleaned parts and prevent a trip and fall hazard to workers. Mr. Mingua also advised SECOR that Safety-Kleen empties and refills the parts washer with the QSOL 300 cleaning solvent as needed. According to Mr. Deprater, the waste oil and hydraulic fluid were picked up periodically for off-site recycling by Safety-Kleen of Plano, Texas. Mr. Deprater indicated that copies of all waste disposal manifests were maintained on file in the office at the facility. Since SECOR's investigation of January 19, 2005, EnXco has vacated 17401 W. Commerce Way. According to Ms. Kathy Tani, Property Manager for Building #6, as of April 1, 2005, EnXco moved out and restored the warehouse and office areas to their original condition. Ms. Tani advised that the concrete flooring in the warehouse area was in excellent condition, and that no staining or evidence of release was observed. Ms. Tani also advised that the warehouse area was renovated and that Bunzl is currently occupying the space. The office space is in the process of being renovated to accommodate Bunzl. 3.5.3 Hazardous Materials SECOR observed 160 pounds of SHC 460 lube oil, 20 gallons of Mobile DTE 11 hydraulic oil, 15 gallons of ISO 32 hydraulic oil, twenty-four 16-ounce cans of Parts Cleaner, twelve 16-ounce cans of Primer Paint, two 55-gallon drums of ISO-320 Ultra Gear lube, and one 55-gallon drum of QSOL 300 cleaning solvent stored within secondary containment in the warehouse area of EnXco at the time of inspection. Waste oil was collected in 55-gallon drums and disposed of by Safety-Kleen, who also serviced the parts washers at the facility. EnXco also utilized propane in its forklifts and for a portable heater used in the warehouse area. SECOR observed five cases of low-grade detergent stored in the warehouse area of Bunzl at the time of inspection. Title III of the 1986 Superfund Amendment and Reauthorization Act (SARA), also known as the Emergency Planning and Community Right-to-Know Act (EPCRA), requires notification to the public of potentially hazardous chemicals in their communities. A facility that is required under the Occupational Safety and Health Administration (OSHA) Act of 1970 and associated regulations to prepare or have available material safety data sheets for hazardous chemicals present at the facility may also be subject to additional requirements under EPCRA if: • The facility also has hazardous chemicals present at any one time in quantities exceeding 10,000 pounds.
