Culver City, California
Project Description:Kleinfelder performed a fast-track, U.S. Environmental Protection Agency (USEPA) funded brownfields site assessment and cleanup, touted by USEPA and the client as an excellent brownfields success story. The project was performed for Culver City under County and USEPA oversight. Located within Inglewood Oil Field, the site had a long history of oil production activity. Based on the site assessment and cleanup results, regulators concluded that the planned use of the site — a public, unleashed dog park — was appropriate, and the dog park subsequently was constructed.
Kleinfelder prepared a Quality Assurance Project Plan and performed both Phase I and Phase II ESAs. Soil samples were collected from multiple locations and source areas including former ASTs, an oil water separator, pumps, piping and apparent crude oil seeps. Kleinfelder also performed vapor sampling. Results indicated impacts to be limited in vertical and lateral extent. During the subsequent cleanup phase of the project conducted by Kleinfelder under a USEPA-approved cleanup plan, 12 soil excavations were sampled and backfilled; 650 feet of abandoned cast iron piping was exposed, clean in place and removed; 1,200 tons of hydrocarbon-impacted soils were excavated for recycling via thermal desorption and confirmation soil samples were collected from excavations and piping trenches. Kleinfelder’s work was in compliance with federal, state and local laws and regulations. The firm was responsible for coordinating activities with the applicable regulatory agencies and for obtaining all the necessary approvals and permits.
Client Issues
- There was a fixed project budget and a tight schedule both for expenditure of USEPA grant funds and dog park construction. The client also requested Kleinfelder’s assistance with preparation of quarterly progress reports required by USEPA.
Kleinfelder's Role
Environmental site assessment and remediation services.
Client Benefits
Kleinfelder successfully demonstrated to USEPA and the County that hydrocarbon concentrations detected in one area of the site were caused by naturally occurring oils from a nearby eucalyptus tree canopy. We thereby avoided having to remediate this portion of the site, saving the city time and money. The project was completed on time and within budget.
