The Port of Los Angeles provides $5.1 billion in state tax revenue, and generates 1.1 million jobs in California.
The Leighton Solution.
Because of our involvement with and knowledge of the project area, contaminants of concern, and construction plans, the contractor selected Leighton to provide daily construction monitoring during grading.
Prior to construction, our services included assisting Herzog with regulatory applications, Notice of Intent (NOI) submitted to the Los Angeles Regional Water Quality Control Board (RWQCB); and Rule 1166 Volatile Organic Compound (VOC) Emissions from soil in accordance with South Coast Air Quality Management District (SCAQMD) requirements. In addition, Leighton assisted Herzog in compiling required plans to comply with the Port’s requirements, including a Health and Safety Plan (HASP), Storm Water Pollution Prevention Plan (SWPPP), and a Waste Management Plan (WMP).
Daily activities included assessing freshly exposed soil for staining, VOC emissions, or other signs of contamination; assisting Herzog to manage site control devices in areas of potential soil or groundwater impact; monitoring dust levels and alerting Herzog when dust suppression is required; inspecting truck clean-off/wash-off areas to ensure that soil, mud, and debris is not being tracked off site.
Two undocumented underground storage tanks (USTs) were encountered during site trenching. The purpose, date of installation, and historic contents of the USTs were unknown. Leighton expedited the tank removal permit process through the Los Angeles Fire Department (LAFD) and removed the USTs in accordance with LAFD Division 5 permit requirements. The USTs and were loaded onto a flatbed truck and transported offsite for proper destruction.
