Airports & Aviation Experience

Airports and airport-related businesses are complex and challenging facilities to manage in today's fast-paced and competitive climate. As we have done at hundreds of airports and Air Force bases, WESTON can provide services to help your business surpass the competition.

For the City and County of Denver (CCoD), Stapleton International Airport (SIA), Denver, CO, WESTON provided full environmental support services for CCoD for the redevelopment of SIA. From 1992-2004, WESTON performed site assessments, remediation, pilot testing, remedial design, regulatory negotiation and reporting, construction, operation and maintenance, asbestos management, waste management, emergency response, litigation support, cost estimating, scheduling, demolition support and oversight, data management, GIS, and Phase I activities.

WESTON maintained a GIS-compatible database containing all analytical data collected at the site to assist in assessment and remediation. Using GIS, WESTON produced maps for CCoD, potential property buyers, and tenants illustrating contaminant concentrations and sitewide hydrogeologic data. GIS was also used to show the locations of contaminant plumes relative to proposed demolition and infrastructure development.

In addition, the City and WESTON prepared a Voluntary Cleanup Plan (VCUP) under the Colorado Voluntary Cleanup and Redevelopment Act (1994) for an abandoned disposal site on Stapleton property. It was the first active VCUP submitted to CDPHE under the program and the third VCUP to be approved. In addition, it was the first plan approved for a site with groundwater impacts.

For Baltimore/Washington International (BWI), Baltimore, MD, WESTON developed standard operating procedures for hazardous waste management and delivered hazardous waste and pollution prevention training to maintenance employees. WESTON also prepared a comprehensive update to the Stormwater Pollution Prevention Plan and worked with tenant pollution prevention teams to ensure implementation of the plan. In addition, WESTON developed a Web-based geographic information system that links areas of environmental concern to relevant data tables, facilitating maintenance of stormwater management structures and helping to ensure NPDES permit compliance.

For Philadelphia International Airport, Philadelphia Division of Aviation, Runway 8-26 Design and Construction,Terminal E, Philadelphia, PA, WESTON provided comprehensive geotechnical/geoenvironmental services to support construction of the new 5,000-ft Runway 8-26. Because the proposed site of the new runway was the former Enterprise Avenue Landfill, a delisted Superfund site, WESTON prepared a National Environmental Policy Act (NEPA) environmental assessment (EA), which required the timely completion of geotechnical and geohydrological investigations to resolve any site geological issues and confirm site integrity for construction of the runway. WESTON also investigated soil contamination; provided National Pollutant Discharge Elimination System (NPDES) permitting services; prepared Safety, Health, and Emergency Response Plans (SHERPs), Spill Prevention, Control, and Countermeasures (SPCC) and Best Management Practices Plans; and developed surface-water/sediment sampling kits for DOA staff for use during implementation of operations associated with the new runway.

WESTON resolved difficult geotechnical engineering issues associated with placement of the new runway over the former Enterprise Avenue Landfill by conducting fast-track, comprehensive, geotechnical subsurface investigations and design. WESTON also conducted a wide range of geotechnical and geoenvironmental services for the construction of a $220 million commuter airlines runway at Philadelphia International Airport, the City’s largest public works project. In addition, WESTON facilitated a proactive partnership with the Philadelphia Division of Aviation (DOA), U.S. Environmental Protection Agency (EPA), the Pennsylvania Department of Environmental Protection (PADEP), and City officials to resolve regulatory obstacles, which resulted in project completion 1 year ahead of schedule.

• RCRA Inspections
• Spill Response Management
• National Guard Armory Site Investigations
• UST Management
• Wetlands Delineation and Mitigation
• Jet Fuel Response

For both Philadelphia International and Northeast Philadelphia Airports, WESTON developed a Pollution Prevention Control Plan that covered spill plans/procedures, materials handling, emergency response, and Best Management Practices to reduce pollutant discharge from both airport and tenant waste generators. We have also conducted annual hazardous material/hazardous waste training for airport management, maintenance, and operations staffs, including key components of RCRA, OSHA, and DOT requirements for regulatory compliance at these two airports.

For Chicago O'Hare and Midway Airports, WESTON has performed comprehensive hazardous waste materials and waste inventories and has conducted a training needs inventory aimed at accident prevention.
