Document Description
The RAW was prepared to address the removal of lead and PCB contaminated soil around the Main Building on the Burlingame High School campus. The removal action objective is to mitigate potential risk to human health and the environment through excavation and offsite disposal of the soil contaminated with lead and PCBs for unrestricted land use. The RAW proposes that approximately 90 cubic yards of soil will be excavated and transported offsite to an appropriate landfill. The excavation to prevent unauthorized entry to ensure worker safety. Access to the project site will be limited by an exclusion zone at least 20 feet from the excavation, stockpile area and excavation equipment.
Up to two truck loads of clean fill may be brought onto the site. The clean fill will be used to back fill and restore the site. The fill will be tested according to the DTSC's "Information Advisory Clean Imported Fill Material" guidance document of October 2001.
Confirmation sampling will be conducted to verify that all soils containing lead and PCB at concentrations of the CGs or above have been property removed, and the site is safe for occupancy as a school. Excavation will continue until the RAO has been achieved. Excavation and confirmation sampling activities will be completed in 14 days.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Section 15330
Reasons for Exemption
The project is consistent with this exemption since:
1. This removal action is intended to eliminate the threat of a release that could expose sensitive populations at a school site and will cost approximately $57,000 to implement.
2. The site is not on the Hazardous Waste and Substances Sites list compiled pursuant to Government Code section 65262.5 and is not in an area of biological or cultural resource significance.
3. This small removal action will not have a significant effect on the environment because:
a. Best Available Control Technology standards of the air quality management
district for excavations will be met by controlling and monitoring fugitive dust and
airborne lead during the remediation. No site specific air permit will be required.
Areas targeted for excavation will be watered down prior to and during excavation
activities to suppress dust. Work will be temporarily suspended if fugitive dust
emissions exceed the criteria established by the air pollution control district. The
monitoring levels for lead are 0.5 mg/m^3.
b. The soil will be stockpiled and placed on an impermeable barrier. The stockpiles
will be covered and fenced when not in use.
c. Approximately seven truckloads of contaminated soil will leave from the site. All
loaded trucks will be inspected, decontaminated and tarped prior to leaving.
Following characterization, wastes will be transported under manifest by a
registered hauler to an appropriate disposal facility.
d. Verification sampling will occur to assure that the removal cleanup levels set by
the screening risk assessment have been achieved in order to eliminate human
health risks.
