12 EXCAVATION, HANDLING AND CAPPING OF CONTAMINATED MATERIAL SECTION SECTION EXCAVATION, HANDLING AND CAPPING OF CONTAMINATED MATERIAL 1.1 DESCRIPTION This section presents a description of remedial excavation activities and contaminated material handling to address areas of concern (AOC) associated with the proposed athletic field development area, including: Excavation and management of contaminated soils identified in connection with the Moore Cartridge waste piles (AOCs 25B and 25C) to address the direct contact and impact to ground water pathway; and Excavation and onsite consolidation of contaminated soils with construction of an engineering control to address the direct contact pathway for the impacted former agricultural areas (AOC 36). Arsenic and lead were reported at concentrations exceeding the Residential Direct Contact Soil Remediation Standard (RDCSRS) at AOC-25B. Arsenic was also reported at concentrations exceeding the site-specific Impact to Ground Water Soil Remediation Standard (IGWSRS) at this location. The contaminated soil was successfully delineated to applicable standards in the north and south directions, but not fully delineated to the east, west, and vertically. Remediation of soil is required to address the direct contact and impact to ground water pathways for this AOC. AOC-25B contaminated soils will be excavated, loaded out and appropriately managed by an offsite facility (i.e. disposed, recycled). Based on the findings of investigations conducted to date it is anticipated that the excavation area will be on the order of 1,700 square feet in area and extend to a depth of 3.0 feet bgs, generating an estimated volume of 190 cubic yards. The extent of the excavation area will be determined based on the results of postexcavation soil samples collected at the frequencies prescribed in NJDEP Technical Guidance for Remedial Action Verification Sampling for Soil (one soil sample for every 30 linear feet of excavation sidewall and one soil sample for every 900 square feet of excavation bottom). Post-excavation soil samples will be analyzed for arsenic, lead and mercury. Soils will be excavated until arsenic, lead and mercury concentrations are at or below the RDCSRS and/or IGWSRS, as appropriate, or until such a time that it is determined that the remaining concentrations do not represent a direct contact or impact to ground water threat. Polynuclear aromativc hydrocarbons (PAHs) and lead were reported at concentrations exceeding the RDCSRS and default Impact to Ground Water Soil Screening Level (IGWSSL) at AOC-25C. In addition, several metals including aluminum, cadmium, manganese, mercury and zinc were reported at concentrations exceeding their IGWSSL and/or site-specific IGWSRS. PAHs have not been delineated in the horizontal or vertical direction. Lead was successfully delineated to the RDCSRS in the west and northwest directions, but was not fully delineated to the RDCSRS in the south or vertical directions. Remediation is required to address the direct contact and impact to ground water pathways for this AOC. AOC-25C Contaminated soils will be excavated, loaded out and appropriately managed by an offsite facility (i.e. disposed, recycled). Based on the findings of investigations conducted to date it is anticipated that the excavation area will be on the order of 760 square feet in area and extend to a depth of 3.0 feet bgs, generating an estimated volume of 85 cubic yards. The extent of the excavation area will be determined based on the results of postexcavation soil samples collected at the frequencies prescribed in NJDEP Technical Guidance for Remedial Action Verification Sampling for Soil (one soil sample for every 30 linear feet of excavation sidewall and one soil sample for every 900 square feet of excavation bottom). Post-excavation soil samples will initially be analyzed for PAHs, aluminum, arsenic, cadmium, lead, manganese, mercury and zinc. Samples may also be analyzed for the same contaminants using SPLP methods. Soils will be excavated until contaminant concentrations are at or below the RDCSRS, IGWSSL and/or IGWSRS, as appropriate, or until such a time that it is determined that the remaining concentrations do not represent a direct contact or impact to ground water threat. Excavation, Handling And Capping of Contaminated Material Section

13 EXCAVATION, HANDLING AND CAPPING OF CONTAMINATED MATERIAL SECTION Pesticides and metals were reported at concentrations exceeding the RDCSRS in surface and near surface soils at AOC-36. Based on sampling conducted to date, the following contaminants were identified on the property: Lots 1 and ,4 -DDT, arsenic, and lead were reported at concentrations exceeding the RDCSRS. Dieldrin, beta-bhc, arsenic, and lead were reported at concentrations exceeding the IGWSSL. No vertical profile sampling has been conducted on Lots 1 and 1.01 to date. Lot 2 No soil contamination associated with historically applied pesticides has been identified based on the findings of investigations conducted to date. Lot 3 Arsenic and lead were reported at concentrations exceeding the RDCSRS and IGWSSL. Dieldrin was reported at a concentration exceeding IGWSSL. Vertical profile sampling conducted on Lot 3 indicates that soil contamination associated with historically applied pesticides extends to a maximum depth of 2.5 feet bgs. Lot 4 Dieldrin was reported at concentrations exceeding the RDCSRS and IGWSSL. Dieldrin also exceeded the site-specific IGWSRS. Vertical profile sampling conducted on Lot 4 indicates that soil contamination associated with historically applied pesticides extends to a maximum depth of 1.0 foot bgs. The proposed development grading design includes excavation of AOC-36 surface and near surface soils from the north portions of Lots 3 and 4 with placement of the excavated soils in the lower lying south portion of Lots 3 and 4. The proposed cut/fill is intended to level the site to facilitate construction of the athletic fields. The proposed development grading plan is presented on Figures 8A through 8C of the Site Investigation/Remedial Investigation (SI/RI) Report Remedial Action Workplan (RAW). As discussed above and as shown on the cross sections presented on Figure 9, the soils with concentrations exceeding the RDCSRS on Lots 3 and 4 extend to a maximum depth of 2.5 feet bgs and 1.0 feet bgs respectively. These soils will be excavated from the north portions of Lots 3 and 4 and placed in the lower lying south portions of Lots 3 and 4 in accordance with proposed development grading plan. Pursuant to the NJDEP s draft Historically Applied Pesticide Guidance consolidated contaminated soils will be placed such that they are not in close proximity to the water table. A minimum two foot buffer between the consolidated contaminated soils and the water table will be maintained. An engineering control will be constructed at the ground surface in areas where the results of investigations identified AOC-36 soil contaminants at concentrations exceeding the RDCSRS. The engineering control will also prevent runoff to surface water features and deciduous wetland areas identified along the banks of Plank Run. The engineering control will be constructed on the south portions Lot 3 and 4 where contaminated soils have been consolidated. Materials utilized to construct the engineering control will meet the requirements for clean fill described in the NJDEP Alternative and Clean Fill Guidance for SRP sites. The engineering control in the consolidation area will consist of a twelve-inch clean fill cap underlain by geotextile for the purposes of visual demarcation. In addition, the engineering control will include the proposed access driveway and parking area. The engineering control in these areas will consist of two inches of crushed stone and six inches of dense graded aggregate obtained from an undisturbed geologic formation. Details including historic investigation activities, physical characteristics, and sampling information for AOC 25B, 25C, and 36 are included in the Site Investigation Remedial Investigation Report (SI/RIR) and Remedial Action Workplan (RAWP) provided with the Supporting Documents. 1.2 GENERAL REQUIREMENTS General conditions and requirement detailed in the Rowan University West Campus Athletic Fields Installation Project Specifications as prepared by Taylor, Wiseman, and Taylor (TWT) are to be incorporated and followed in the execution of this Work Scope.
