Review all recorded chain of title, deed, environmental cleanup liens, other real property records, utility systems, or other available documents to ascertain prior uses of the real property that may have involved hazardous substances or petroleum that may have contaminated the property, or created environmental risks. Conduct a visual or physical inspection of adjacent properties (may be on or adjacent to the installation) to assess current and former property use(s) to the extent possible. Review of all available surveys or inspection reports regarding asbestos, polychlorinated biphenyl's (PCBs), lead (including lead -based paint), radon, underground storage tanks and piping systems, solid waste management units, air pollution emission inventories, Environmental Compliance Evaluation Program (ECE) reports, environmental engineering work place surveys, bio-environmental engineering and annual industrial hygiene surveys. The project team updated the lead risk assessment and attached to the ECP Checklist Additionally, the KMEA team identified asbestos -containing material (ACM). The following building components suspected of containing ACM including: thermal system insulation (TSI), vinyl floor tile, mastics (roof, tile, baseboard, and basecove, roofing material, acoustic ceiling tiles, spray -applied acoustic ceiling material, and drywall were surveyed and documented. At the conclusion of the project, a Draft Final and Final ECP Checklist was prepared including the following: a) A preliminary site characterization summary b) Professional data presentation (including tabulated data, graphics, and interview summaries) c) Copies of California certifications for the lead -based paint risk assessors. d) Presentation (in an appendix) of the regulatory database search report. The reports summarized the status of long-term solid waste activities and included a Master Schedule of all planned and anticipated environmental response activities. The project was completed within the designated budget and schedule and the Navy has since successfully transferred the property as intended. Title — Environmental Due Diligence Site Characterization and Phase II Environmental Site Assessments in Support of the San Ysidro Land Port of Entry Expansion Project Location — San Ysidro, CA Date Completed - 2014 Client — General Services Administration (GSA) Total Value - $180,000 Client Reference — Damon Yee, (415) 522-3168, damon.yee@gsa.gov Project Description - The U.S. General Services Administration is conducting a $741 million -dollar complete reconfiguration and expansion of the San Ysidro Land Port of Entry (LPOE). The San Ysidro Land Port of Entry (LPOE) is the busiest land border crossing in the Western Hemisphere. As part of this multiphase project, Phase I and Phase II Environmental Assessments and due diligence studies were conducted in accordance with American Society for Testing and Materials (ASTM) Standard E1527. These studies were performed to evaluate the environmental condition of properties within the footprint of the planned construction prior to the transfer of the real estate ownership to the GSA. Scope of work included initial coordination meetings with the project designers, architects, construction team and the GSA project management to develop strategies for timely and cost-efficient methods for acquiring environmental information. The information would then be used by the GSA to make informed decisions regarding the selection and acquisition of real estate for the planned LPOE reconfiguration. Scope also consisted of permitting process through the application of the Clean Water Act and State Water Resources Control Board Conditional Waiver 10 for Waste Discharge to Land to allow transfer and reuse of construction related excavated soils at nearby private land under development instead of shipping to the local Otay Mesa landfill. The environmental investigations involved the collection of soil and groundwater samples and analytical laboratory testing to check for presence of target chemicals of potential concern, evaluation and interpretation of the chemical data acquired and reporting and presentation to the GSA and the Regional Water Quality Control Board (RWQCB) technical staff. Statistical analyses were performed on soil chemical data obtained from several thousand tons of materials excavated as part of the reconfiguration project.
