The in-place UST abandonment went well this past week with a current Terra-Petra project in the Downtown Los Angeles area. LAFD Inspector Sanchez was satisfied with the procedure. Next step in the process will be to follow through with the soil borings, sampling and testing, and the investigative results shall be compiled in the UST Closure Report to LAFD.
Approximately 558,000 underground storage tanks (USTs) nationwide store petroleum or hazardous substances. The greatest potential threat from a leaking UST is contamination of groundwater, the source of drinking water for nearly half of all Americans. EPA, states, and tribes work in partnership with industry to protect the environment and human health from potential releases.
Project directed by Dave Lucero for Terra-Petra Environmental Engineering. Here are some preliminary photos.
