ECS conducted a Phase I Environmental Site Assessment (ESA) of the site in 2014 (ECS Project No. 09-24723). The site is an approximate 2.55 acre area that contains four parcels. The subject site contains a three-story former manufacturing building that has been up fitted with office/business spaces. The building is currently occupied by numerous businesses. The building is cooled with a chiller system and several of the individual units are heated with electrical heat pumps. During the site reconnaissance, what appeared to be a pit was observed below the surface of the chiller room in the basement of the building. This pit appeared to be filled with a water/oil mixture. Site Photographs are included in Appendix A. The potential for a release from this pit was considered to be a recognized environmental condition (REC) of the site. ECS estimated that the pit was approximately 20 feet long, 10 feet wide, and 10 feet tall with an estimated 1,250 gallons of liquid. To remove the liquid in the pit as a potential source of ongoing contamination, ECS was contracted by Mr. Paul Loukas with Cape Fear Commercial to remove the existing liquid from the pit and clean the floor and walls of the pit. Project information is based on a conversation between Mr. Loukas EDG and Mr. Randy Cavallier of ECS and the previously cited report. 2.0 FIELD ACTIVITIES 2.1 Introduction to Scope of Work The project consisted of collecting a sample of the liquid from the pit for laboratory analysis to determine if the material was to be handled as hazardous or non-hazardous waste. Following the waste determination, ECS contracted with Zebra Environmental and Industrial Services, Inc. (Zebra) to remove and dispose of the liquid and clean the floors and walls of the pit. 2.2 Waste Determination On January 13, 2016, ECS personnel collected a sample of the liquid from the pit. The sample was collected using a disposable polyethylene bailer and new length of nylon cord. The sample consisted of clear liquid and very viscous oil. The sampler wearing a new pair of nitrile gloves placed the samples in laboratory prepared containers, labeled them, and placed them into a cooler with ice to maintain the samples at a temperature of 4°C. The samples were transported to Research and Analytical Laboratories, Inc. (R&A) to be analyzed for volatile organic compounds (VOCs) using EPA Method 8260, semi-volatile organic compounds (SVOCs)using EPA 8270BNA (base neutral and acid extractable), and RCRA metals using the Toxic Characteristic Leachate Procedure (TCLP). The analysis was required by Zebra for their disposal determination (hazardous or non-hazardous). A COC was maintained during the sample collection and transportation process and is included in Appendix B. Waste Removal and Disposal Report West Salem Square 1001 South Marshall Street Winston Salem, Forsyth County, North Carolina ECS Project 49.1119 March 21, 2016 2 Laboratory analytical results did not detect target VOCs, SVOCs or metals above the laboratory quantitation limits; therefore, the liquid was considered non-hazardous. The laboratory analytical data sheets are included in Appendix B. 2.3 Liquid Removal and Disposal On January 29, 2016, ECS and their environmental contractor, Zebra Environmental Services (Zebra) mobilized to the site. Zebra utilized a vacuum truck to remove the liquid. Upon removal of approximately 6,000 gallons of liquid from the pit, Zebra personnel were able to access the pit and determined that the pit was in fact a much larger boiler/mechanical room, complete with a boiler and associated piping. The boiler room was also connected to a room of unknown size. The boiler room was measured to be 60 feet long, 10 feet wide, and 10 feet tall. The adjoining room was measured to be 12 feet long, 12 feet wide, and 10 feet tall (See Photographs, Appendix A and Figure 3). At that time, 6,800 gallons of liquid and 75 gallons of sludge had been removed by Zebra. The Material Manifests for the waste is included in Appendix C. Between February 4 and February 8, 2016, ECS and Zebra returned to the site to complete the project. Upon further inspection, the material coating the boiler, piping, walls, and floor was a semi-solid material that could not be removed using the vacuum truck. Zebra physically scraped the material off the floors, walls and equipment and placed it into drums for disposal. There was also wood debris and old piping, pumps, and motors that were removed and disposed of. Following the removal of the liquids, sludge, and debris, Zebra cleaned the walls, floors and ceilings of the rooms and the boiler equipment and associated piping using a high-pressure steam cleaner, degreasers, and scrapers. The wash water was removed using the vacuum truck. An additional 5,400 gallons of liquid and 893 gallons of sludge were removed and transported for disposal during this phase of the project. The Material Manifests for the waste is included in Appendix C. A vault and/or tank of unknown size was discovered beneath the smaller room. The tank was full of liquid. On March 7 and March 8, 2016, Zebra returned to the site to pump out the vault/tank and to access it for cleaning. The vault was constructed of concrete and measured 10 feet long, 10 feet wide, and 5 feet tall. An 18-inch diameter 4-foot deep sump was located directly beneath the opening in the floor of the smaller room above (See photos). Approximately 3,900 gallons of liquid, 125 gallons of sludge, and 725 pounds of metal and concrete debris was removed from the vault. The Material Manifests for the waste is included in Appendix C. 3.0 CONCLUSIONS Laboratory analytical results of the material which had accumulated on the boiler room floor did not detect target VOCs, SVOCs or metals above the laboratory quantitation limits; therefore, the liquid was considered non-hazardous. Zebra removed a total of 16,100 gallons of liquid, 1,093 gallons of sludge, and 725 pounds of metal and concrete debris for off-site disposal from the site. Zebra did not report and photographs do not show breaches, cracks, or holes in the concrete floors or walls of the vault.
