Large-Scale Remedial Excavation Adjacent to Freeways of Former Printing Plant
- Significant lead and hydrocarbon soil impact
- Excavation Area located adjacent to Major Freeway embankment
- Due to the excavations, depth and location shoring was required to support the embankment and allow excavation to 25-ft below grade
- Excavated approximately 5,264 cubic yards of soil
- Transported offsite for disposal 3,516 tons of lead-impacted soil to a Class I disposal facility and 2,541 tons of hydrocarbon impacted soil to a Class II disposal facility
- Stockpiled and backfilled soil for native backfill and imported clean backfill for compaction
- Performed 1166 air monitoring and T-1 Trench monitoring
- Acquired City approval and performed remedial excavation under expedited status due to property transfer
EEC Environmental (EEC) was retained by a major telecommunication company for environmental assistance. The Printing Plant had been in operation for since the 1930’s. During a due diligence investigation prior to a property transfer, an area located adjacent to a Freeway was identified as containing lead and hydrocarbon contamination above regulatory limits.
EEC conducted a soil investigation and determined that an area located adjacent to the freeway had been impacted by semi-volatile organic compounds, diesel, gasoline, oil, volatile organic compounds, and lead. Due to an upcoming property transfer; remedial excavation was selected as the appropriate means to remedy the impacted area to achieve the necessary timeline.
EEC prepared a Remedial Action Plan and acquired the necessary city permits for shoring and grading along the property boundary. The area was excavated and the site was issued closure from the County within 9-weeks of the start of the project.
