City of Philadelphia, Police Site 013 – Site Characterization

Philadelphia, Pennsylvania

Date of Service: 2009 to 2013
Services Performed: UST Removal Oversight, Site Characterization and PADEP Act 2 Site Remediation

The Police Site 013, Site Characterization project is currently being conducted by Oxford Engineering Company under the City of Philadelphia, Environmental Consultant Services contract. This site is utilized as a parking area and refueling site for the Police vehicles associated with the Philadelphia Police 26th District. As part of a city wide Memorandum of Agreement (MOA), more that twenty-five storage tank systems in the City of Philadelphia were upgraded. As part of the upgrade process, an on-site 10,000 gallon capacity gasoline underground storage tank system was identified as having a potential release in 2009. As a result, the PADEP required appropriate corrective action for the facility as regulated under Title 25, Chapter 245, subchapter D.

Oxford prepared and submitted USTIF claim documentation for this site on behalf of The City of Philadelphia. Oxford interfaced with USTIF for the claim submittals and was successful in securing partial reimbursement for the Site Characterization and Remediation. Oxford initiated the site characterization program in the fall of 2012. The site characterization program included advancement of soil borings with a conventional drill rig, screening and collection of soil samples for laboratory analyses. Groundwater monitoring wells were installed at locations that appropriately characterized the potential release. A vapor intrusion investigation was conducted through soil gas sampling and no vapor intrusion risks were identified. Quarterly groundwater monitoring, site characterization activities and reporting are continuing at this site.

City of Philadelphia, Fire Site 013 – UST Removal Oversite & Site Characterization

Philadelphia, Pennsylvania

Date of Service: 2010 to 2013
Services Performed: UST Removal Oversight, Site Characterization and PADEP Act 2 Site Remediation

The Fire Station 112, Site Characterization project is currently being conducted by Oxford under the City of Philadelphia, Environmental Consultant Services contract. The site is presently occupied by an active fire station (Station 112). As part of a citywide Memorandum of Agreement (MOA), more that twenty-five storage tank systems in the City of Philadelphia were upgraded. As part of the upgrade process, two underground storage tanks were identified and removed at the subject property. Initially, only one 550 gallon diesel fuel UST was believed to exist at the site. However, upon the removal process, a second 2000 gallon gasoline UST was found below the first tank. Soil samples collected by Oxford as part of the UST closure revealed regulated compounds exceeding the Act 2 statewide health standard. Based on this exceedance, further site characterization was required.

Oxford initiated a site characterization program in the winter of 2013. The site characterization program included advancement of soil borings with a geoprobe unit, collection screening and collection of soil samples for laboratory analyses. Groundwater was not encountered at the terminating depth(s) of the soil borings. Three (3) groundwater monitoring wells were installed at locations that appropriately characterized the potential release. Quarterly groundwater samples were collected from each well for laboratory analyses. Quarterly groundwater monitoring, site characterization activities and reporting are continuing at this date.

City of Philadelphia, Police Academy – UST Removal Oversight

Philadelphia, Pennsylvania

Date of Service: 2012
Services Performed: GPR Survey, UST Removal Oversight, Site Characterization and PADEP Reporting

The PoliceAcademy, UST Removal Oversight and Site Characterization project was conducted by Oxford Engineering Company in the summer of 2012 under the City of Philadelphia, Department of Public Property, Environmental Consultant Services contract. Oxford conducted an electromagnetic (EM) metal detection, conductivity and ground-penetrating radar (GPR) survey at the site in order to locate three (3) previously closed in place gasoline underground storage tanks (USTs) in close proximity to planned new construction at the site. Construction activities at the PoliceAcademy site required the access and removal of the three (3) previously closed in place USTs. The USTs were uncovered and found to have been filled with cement slurry during the closure process. During the UST removal activities the tanks were observed to be in deteriorated condition and localized petroleum impact to the soils adjacent to the tanks was evident. Groundwater was encountered in the base of the tank excavation and was also suspected to have been impacted. Oxford performed oversight of the UST and impacted soil/groundwater removal activities and collected confirmatory/characterization soil and groundwater samples to document the then current site conditions.

Oxford conducted a subgrade soil and groundwater investigation of the UST excavation in order to screen and collect regulatory compliant confirmatory soil and groundwater samples from the perimeter of the UST excavation. Geo-probe soil probes were advanced at the perimeter of the former UST excavation to evaluate soil conditions at the former excavation sidewalls. Temporary slotted PVC well points were established at two (2) of the probe locations. Grab groundwater samples were collected from each well and laboratory analysis revealed no exceedance of the PADEP Closure Site Water Standard/Action Levels for any of the target compounds analyzed. OEC prepared and submitted the required UST Closure Report, UST Registration Forms and Amended UST Registration Forms to PADEP on behalf of the City of Philadelphia.

City of Philadelphia, Pleasant Playground – UST Removal Oversight

Philadelphia, Pennsylvania

Date of Service: 2012 to 2013
Services Performed: GPR Survey, UST Removal Oversight, Site Characterization and PADEP Reporting

The Pleasant Playground, UST Removal Oversight and Site Characterization project was recently conducted by Oxford Engineering Company in 2012 under the City of Philadelphia, Department of Public Property, Environmental Consultant Services contract. During site grading and excavation activities for the construction of a new community center at the Pleasant Playground site, the general contractor encountered a previously unknown steel underground storage tank (UST). The tank was determined to have previously contained gasoline. Oxford conducted an electromagnetic (EM) metal detection, conductivity and ground-penetrating radar (GPR) survey at the site and the survey revealed four (4) additional steel tanks at approximately 1 to 3 feet below grade.

Oxford performed oversight of the UST systems removal activities and collected confirmatory/characterization soil samples to document the then current site conditions. Visual inspections revealed no evidence of holes in any of the steel tanks and no obvious contamination was observed in any of the tank excavations. Confirmatory soil samples were collected from beneath each tank and at the presumed locations of the former fill connection and the former product delivery line connection of each tank. Laboratory analytical results showed that there were no exceedances of the PADEP Closure Site Unsaturated Soil Standard Residential Action Levels for any of the target compounds analyzed. OEC prepared and submitted the required UST Closure Report, UST Registration Forms and Amended UST Registration Forms to PADEP on behalf of the City of Philadelphia.

City of Philadelphia, FDR Park Heating Oil UST – Site Remediation

Philadelphia, Pennsylvania

Date of Service: 2005 to 2012
Services Performed: UST Removal Oversight, Site Characterization and PADEP Act 2 Site Remediation and Reporting

Oxford recently completed the site characterization, remedial design and negotiation with PADEP to obtain PADEP Act 2 liability protection for the City of Philadelphia, FDRPark, Heating Oil UST removal site. In the spring of 2005, it was determined that a 1,000 gallon capacity UST used to store #2 heating oil had leaked resulting in localized soil and groundwater contamination at the FDR Park Recreation Maintenance Building. The fuel oil tank system and the associated contaminated soils were removed from the site. Confirmation sampling indicated that the full extent of the soil contamination proximate to the underground tank had been removed.

Based on the monitoring well network installed as part of the preliminary site characterization, it was determined that a small plume of dissolved phase and separate phase liquid (SPL) had migrated to the southwest of the former UST location. However, the extent of the plume was limited and based on eight (8) quarters of groundwater sampling and passive free product recovery, it was determined that the plume had not impacted a near by surface water body. It was determined that the site-specific remedial standards were the most applicable standards for the existing site conditions. To meet these standards Oxford instituted a scope of additional site characterization and prepared a formal site characterization document submitted to PADEP in March 2011 in accordance with the requirements set forth in the PADEP storage tank regulations (Act 32) and the Land Recycling Program (Act 2). In July 2011, the City of Philadelphia received PADEP confirmation that the site groundwater had been remediated to the nonresidential Statewide Health Standard and site soils had been remediated to a nonresidential Site-Specific Standard and attainment of Act 2 liability protection. In July 2012 the site monitoring wells were properly closed in accordance with PADEP requirements.
