PRIVILEGED AND CONFIDENTIAL PREPARED AT DELPHI CORPORATION'S COUNSEL'S REQUEST Elimination System (NPDES) Permit (#CAS000001). A copy of the general stormwater permit as well as the most recent stormwater discharge analytical data were reviewed by CRA as was a recent (8/2002) RWQCB inspection report. The facility had corrected the deficiencies as noted by the RWQCB and is now in compliance. The last exceedance of the 0.050 mg/L RWQCB stormwater benchmark for lead was in January 2001. 3.11 AIR EMISSIONS The Delphi facility has air pollution control permits for approximately 76 different sources of air contaminants (Table 4). Most of the exhaust of the entire building passes through baghouses with the exception of heat exhausters in the Barton Pod area, the warehouses, and the new cell area in the facility. The principal emissions from the Delphi facility are lead and sulfuric acid. Delphi maintains three Site perimeter air samplers from which samples are collected every six days. These samplers have not recorded ambient air concentrations of lead in excess of the ambient air quality standard of 1.5 ug/m3. In addition to the perimeter air sampling, Delphi conducts air emission calculations based on facility production, processes and materials used. This information is used to document permit compliance. CRA reviewed these data and the facility is in compliance with the permit requirements. All permits are current. Site personnel interviewed during the course of the Site inspection were not aware of any adverse impacts to the Site related to the operation of air emission equipment by Delphi. No adverse impacts to the Property from air emission sources were observed by CRA during the Site inspection. 3.12 ASBESTOS CONTAINING MATERIALS (ACM) The presence of ACM at the Site was investigated through discussions with facility personnel and visual observations made by CRA. No intrusive investigations were conducted to examine areas of concealed space and no samples were collected. Facility representatives were aware of ACM being present in the buildings, primarily in association with the boilers and associated steam lines. They were not aware of any ACM surveys that had been conducted at the Site. Facility representatives indicated that to their knowledge, only small amounts of asbestos have been removed from the Site. 37616 -01(2) 25 CONESTOGA-ROVERS & ASSOCIATES
PRIVILEGED AND CONFIDENTIAL PREPARED AT DELPHI CORPORATION'S COUNSEL'S REQUEST This is documented by August 1998 and October 1989 reports, which document asbestos removal activities. An ACM survey was not conducted as part of this ESA. Based on observations during the Site inspection and due to the age of the buildings, it is likely that ACM is present. Potential ACM observed by CRA was limited to ceiling tile and floor tile in office areas. For the production and warehouse areas, suspect ACM consisted of bricks, roof mastic, drywall joint compound, floor tiles, piping insulation, spray on fire proofing, furnace and boiler insulation, and other mastics. All materials were observed to be in good condition. 3.13 POLYCHLORINATED BIPHENYLS (PCBs) Electrical service to the Site is provided by Anaheim Public Utility through two separate lines that feed 7 on-Site transformers. According to Site personnel, these transformers do not contain PCBs and a PCB survey of the facility had been conducted. Documentation of this was not available and the transformers were not labeled. No leaks from the transformers were observed. There is also an out-of-service electrical transformer stored outside the production area. The transformers are reportedly owned by Delphi. According to Site personnel, no PCB-containing equipment has been or is currently being used, stored, or handled at the Site. At the time of the Site inspection, potential PCB-containing equipment observed by CRA included the electrical transformers. Site personnel were unable to provide documentation of the age of the transformers or analytical testing for PCBs in the dielectric fluid. Potential PCB equipment also included the ballasts in the fluorescent lighting and high intensity discharge fixtures in the buildings. With the exception of the out-of-service transformer, the potential PCB-containing equipment observed by CRA was in operation and appeared to be in good working condition. 3.14 IONIZING RADIATION According to Site personnel, the Site has not used any sources of ionizing radiation in plant operations. No labeled radiation sources were observed by CRA during the Site inspection. Site personnel were unaware of any radon gas testing having been 37616 -01(2) 26 CONESTOGA-ROVERS & ASSOCIATES
