Little Tokyo Service Center vs the Los Angeles City Oil Field
As of April of this year Terra-Petra’s Geological Team has managed the handling, monitoring, reporting and disposal of contaminated soil for a unique project in downtown Los Angeles. The project is being developed by Little Tokyo Service Center, a well-respected developer of affordable housing projects throughout the Los Angeles area. The project in question sits in the Los Angeles City Oil Field, which back in the late 1800’s used to be littered with oil wells and derricks (see photo). There have been 3 oil wells already discovered on this site and potentially two more that may be encountered before the excavations are finished. The site has been affected by Total Petroleum Hydrocarbons (TPH), Volatile Organic Compounds (VOC), Tar, Metals and Methane. Much of this contamination is naturally occurring and typically for a site with oil well activities.
The Little Tokyo Service Center project falls under the management of many agencies; The Los Angeles County Fire Department Health Hazardous Materials Division, The Los Angeles City Fire Department Harbor Industrial Unit, South Coast Air Quality Management District, The Division of Oil Gas and Geothermal Resources and the Los Angeles Department of Building and Safety. We have been working diligently to make sure that the project is in complete compliance with the governing agencies listed above. Our experience and previous relationships with these agencies have served us well to expedite matters in a timely fashion on this project. The lead agency on this project being LA County Fire.
Our responsibilities on this project have included preparing and submitting administrative forms such as Work Plans, Health and Safety Plans, site maps, soil sampling and testing plans, soil gas monitoring logs, boring logs, excavation logs and waste manifests. We have been managing and maintaining general and site-specific requirements of a Contaminated Soil Mitigation Plan pursuant to the AQMD Rule 1166 guidelines. We are now in the process of conducting additional soil characterization and testing to determine the vertical extent of the contamination, ground water monitoring, complete soil gas survey and a Human Health Risk Assessment as directed by the LA County Fire Department.
Our Geological Team is led by our Petroleum Geologist Larry Barnes. He is supported by our Certified Hydrogeologist Steve Maddox and Brian Beltz, Professional Geologist.
