resulted in approximately three million pounds of carbon dioxide emissions.
Therefore, the project objectives were to identify an on-Site, sustainable remediation technology capable of meeting RWQCB cleanup objectives to allow for soil reuse at a competitive cost and within a timeframe consistent with property redevelopment goals. Based on a feasibility study (FS) and technology screening process, an integrated bioremediation approach was selected for pilot testing.
The approach integrates three technological elements including: (1) a proprietary blend of Pseudomonas spp. bacteria engineered in the laboratory to degrade hydrocarbons, (2) an Environmental Protection Agency (EPA) approved “bacteria-friendly” surfactant, and (3) a mobile, customized soil processing system (SPS).
To evaluate bioremediation as the remedial approach for the Site, a pilot test was conducted on 300 tons of TPH-impacted soil. Post-treatment sampling and analysis confirmed a nearly 90% reduction in TPH C6-C40 and more than 95%

reduction in TPH gasoline range organics (GRO) after one month of treatment.
Near asymptotic reductions were documented during the second and third months of the pilot test. The pilot test results demonstrated that the bioremediation approach could meet the RWQCB cleanup criteria of 1,000 milligrams per kilogram (mg/kg) for TPH diesel- and motor oil-range organics (DRO and ORO) and 100 mg/kg for TPH GRO over a short time period. Full scale implementation included stockpiling the treated soil in windrows lined with 30-mil high-density polyethylene and covered with 6-mil plastic. The soil treatment stockpiles were engineered and constructed with a vapor collection and treatment system required for the air permit. The air permit also required installation of a vapor mitigation system on the SPS during application of the bacteria solution.

A former Department of Defense bulk fuel distribution facility (Site) located in an urban, residential setting required cleanup under California Regional Water Quality Control Board (RWQCB) oversight for redevelopment as a retail center and city park. Contaminants of concern (COC) were total petroleum hydrocarbons (TPH) primarily in the diesel range (C13-C22) with lesser amounts in the C4-C12 and C23-C40 ranges. During the public participation process and in consultation with city officials, it was determined that an alternative to large scale trucking through the city was desired. The excavation and off-Site disposal alternative would have resulted in ~8,000 truck trips transporting contaminated soil through city neighborhoods and returning with clean fill based on the ~100,000 tons of TPH-impacted soil requiring remediation. During the California Environmental Quality Act-required evaluation, it was also determined that an alternative to large scale trucking through the city was desired.
