ABSTRACT

Environmental regulation of oil in stormwater discharges is becoming increasingly more stringent, especially in environmentally sensitive areas. When modifications were done to the Camarillo (Ventura County), California Airport in 1997, a high efficiency oil-water separator was installed to treat the stormwater runoff from the area where the trucks used to refuel the airplanes were filled.

The system includes a precast concrete separator vessel, provided with multiple angle enhanced gravity separator plate packs. Performance tests were performed on the system as part of the acceptance procedure, and results of the testing are presented, along with the results of three years of operation and maintenance.
