Crude Oil Pumping and Transmission Station—200-Acre Pump Station Facility


A pragmatic technical approach for characterizing the nature, and vertical and horizontal extent of, potential subsurface chemical constituents and asbestos debris.


Landmark successfully performed environmental project and program management at a 200-acre crude oil mainline pump station facility. This 10-year project included: excavation and removal of asbestos and petroleum contaminated soil; demolition and removal of above- and below-grade infrastructure; soil and groundwater investigations; subsurface infrastructure investigations using ground penetrating radar (GPR); site restoration; and ongoing asbestos operations and maintenance. Landmark successfully performed asbestos and environmental investigations and designed and managed soil remediation and demolition without safety incident.

Landmark developed and implemented a Soil Characterization and Management Plan (SCMP) for specific planned soil excavation activities in areas with asbestos. The SCMP allowed for flexibility and safety during site operations and became an established precedent during the development of evolving asbestos contaminated soil (ACS) regulations. Potential chemical impacts were accurately characterized and remedies were technically evaluated, including options for Voluntary Cleanup.

Project Highlights

  • Site Sampling and Characterization, Abatement Project Design, Contractor Specifications and Health and Safety Plans were successfully developed and implemented without safety incident.
  • Strategic air monitoring programs were performed to document compliance with regulations for airborne asbestos.
  • Performed technical review of safety and worker exposure assessments; managed emission control and respiratory protection programs.
  • Supported development of a pragmatic technical approach for characterizing the nature and vertical and horizontal extent of potential subsurface chemical constituents and asbestos debris.
  • Groundwater monitoring wells were installed along a drainage area within an identified paleochannel to assess the extent of groundwater contamination, gradient, and flow direction, and the potential for off-site migration of contaminated groundwater.
  • Characterization reports provided an interpretive link between the chemical data, geotechnical data, field observations, and the interpreted hydrogeologic and physical environment.
