iCLE/NFELOER &gMhnPh.Pi9htfolufnm. • Various truck repair related chemicals (new/used oil, transmission fluid, antifreeze, grease) are present throughout the repair/maintenance areas of the building on Parcel 1. These chemicals were observed to be stored in 55-gallon capacity (or less) drums and ASTs. Paint containers (less than 1 gallon capacity) are stored in a paint mixing room of the body shop area of the building on Parcel 1. Minor staining was observed throughout the repair/maintenance areas. The areas of staining are considered to be a de minimis environmental condition, and not a REC likely to have impacted soil, soil vapor or groundwater beneath the Site. • A three-stage, closed loop oil/water separator is located outside the northern portion of the building on Parcel 1. This oil/water separator receives run-off from truck wash bays located north of the building. Filtered water from the separator is sent to an onsite evaporator where the water is evaporated out. The remaining sludge in the separator is periodically cleaned and stored in 55-gallon drums prior to be hauled offsite by an outside contractor. A three-stage, closed loop oil/water separator is also located near the northeast corner of the building on Parcel 3. Wastewater from truck washing activities on the east side of the shop building was reportedly captured through strip drains along the perimeter of the building and the wash rack area, and routed to the oil/water separator. The potential exists for undocumented releases to occur from subsurface features, such as oil/water separators, which represents a REC. • The Site consists of septic tanks and associated leach lines. Parcel 1 consists of a septic tank and leach lines on the southern portion, near the entrance to the parcel from East Transportation Court. Parcel 3 consists of two septic systems consisting of tanks and leach lines on the northeastern portion of the parcel. The septic system on this parcel consists of a permitted sewage package treatment plant, which includes two tanks (approximately 8,000-gallons each) and two associated three-stage clarifiers. This treatment plant was installed and used by Schneider to capture wastewater from bathrooms, showers and a clothes washer located in the office area of the building. A septic tank in this same area was used as a pump station for the treatment system. The septic tanks, leach lines, and treatment systems are located outside the areas of truck repair/maintenance areas and are not considered RECs likely to have impacted soil, soil vapor or groundwater beneath the Site. 20172543.001A/STO16R49461 Page 49 of 54 November 2, 2016 02016 Kleinfelder �.kleinfelderxom
