DFW Airport recognized they did not have a firm grasp on the extent of contamination at the site nor a mechanism for managing this material. Complicating the construction effort was an enforcement action received from the Texas Commission on Environmental Quality (TCEQ) alleging discharges of jet fuel at the airport. As a result of this enforcement action, TCEQ sought to stop all construction.
The initial goal of the environmental program was to assist with addressing the state’s environmental concerns while ensuring that the development program was not delayed by these issues. Argus worked with the TCEQ to develop protocols and strategies that would ensure that environmental issues were addressed during construction. Argus established institutional controls, allowing clean-up goals based on true exposures. Approval was obtained for reuse of impacted soils on airport property and for developing a recycling program of impacted cement treated base (CTB) and concrete rubble. This resulted in substantial cost savings by eliminating delays in the construction project and disposal costs for over 124,000 tons of soil and all generated CTB and concrete. In the end, TCEQ allowed the construction to continue under Argus’ oversight and guidance.
