- Ontario Airport Fueling System
Burn & McDonnell is performing a Phase II environmental investigation at the request of the state and Los Angeles World Airports (LAWA) to evaluate and delineate environmental conditions in the area where underground storage tanks (UST) were removed. The objective is to evaluate the existence of hydrocarbon contamination around the former UST area. This will involve utility locating, drilling of soil borings, soil sampling, analytical laboratory testing and compilation of a report containing the investigation results, conclusions and recommendations.
Coordination with LAWA, San Bernardino County, the city of Ontario, the state of California and Aircraft Service International Inc. (ASII) is complex and requires numerous updates and meetings regarding the progress of this project. Close coordination with the airport construction management is ongoing to limit the impact on airport operations.
- Engineering, compliance and permitting
- Design-build services for modification of existing fueling storage system
- Underground storage tank (UST) removal
- Assessment of environmental conditions post-UST removal
Burns & McDonnell was retained by ASII to perform the assessment of the on-airport fuel system. After conducting an engineering and compliance assessment, Burns & McDonnell acted as the prime construction contractor for the installation of a surge suppressor, pressure relief valve, 5,000-gallon UL2085 above-ground product recovery tank (PRT), and relocation of existing sump separator. The PRT is to receive fuel from the pressure relief valve, filter vessel relief lines and the sump separator. When sufficient fuel has accumulated in the PRT, or as desired by ASII, the PRT is discharged through the existing filter vessels and out to the fueling islands, where the fuel can be loaded into refuelers.
The second phase of the project consisted of the removal of one 20,000-gallon underground gasoline storage tank (UST), one 20,000-gallon underground diesel storage tank, and five 40,000-gallon underground jet fuel storage tanks from the ASII fueling facility at Ontario International Airport. After UST removal, about 2,800 tons of petroleum-contaminated soil were removed from the excavation and transported to Thermal Remediation Solutions in Azusa, Calif., for off-site treatment and disposal by low-temperature thermal desorption. Field observations and laboratory analyses of soil samples taken during the UST removals indicated that a release of petroleum hydrocarbons had occurred at the site.
