The project involves approval of a Removal Action Workplan (RAW) for the planned 22-acre elementary school to be located at the northeast of North Fowler and East McKinley Avenue Alignment (Site). The RAW includes a detailed engineering plan for conducting the removal action, a description of the on-site contamination, and the
goals to be achieved by the removal action. The recommended removal action remedy combines excavation with off-site disposal of the impacted soil. The activities that would be conducted to implement the removal action include:
• Excavating approximately 970 bank cubic yards of impacted soil (approximately 1,550 tons) from identified locations;
• Stockpiling excavated soils on-site and perform waste-profile testing of the stockpiled soil;
• Conducting confirmation sampling, comparing confirmation data to the cleanup goals (CGs), and if necessary, over-excavating additional volume until the CGs are met;
• Loading and transporting approximately 1,550 tons of impacted soil to an appropriate disposal facility;
• Conducting perimeter air monitoring to ensure dust is not migrating off site;
• Implementing dust suppressant measures; and
• Backfilling the excavation areas up to level with the surrounding grade using soil derived from non-impacted portions of the project site.
It is estimated that the removal of 1,550 tons of impacted soil would require approximately 60 truck trips to remove. After the waste-profile laboratory testing is complete, an appropriate permitted landfill will be selected based on the results of
the testing. If the soil is determined to be non-hazardous waste, it will likely be disposed of at the Republic Services, Forward Landfill, 9999 South Austin Road, Manteca, California. If the soil is determined to be RCRA hazardous waste or
hazardous waste, it will likely be disposed of at the Clean Harbors Buttonwillow Landfill, 2500 West Lokern Road, Buttonwillow, California, or at the Chemical Waste Management Disposal Site, 35251 Old Skyline Road, Kettleman City, California. After the disposal facility is determined, the soil will be loaded into end-dump trailers/trucks that will be covered with tarps prior to leaving the site for the disposal facility.
The Department of Toxic Substances Control (DTSC) utilized information and analysis in the Fowler-McKinley Elementary School Project Initial Study/Mitigated Negative Declaration (IS/MND) and Addendum to support a final determination about the type of environmental document required to be prepared for the proposed Removal Action Workplan for the Planned Elementary School Site 22 Acres Northeast of Fowler & McKinley Avenue Alignment as provided by Sections 15162, 15163, and 15164 of the CEQA Guidelines. The IS/MND was adopted by the Clovis Unified School District Board of Education on January 16, 2019. The Addendum evaluated the potential environmental effects of the RAW. The revisions incorporate changes in the previously approved project to include the cleanup and haul away associated with
the proposed remediation action of the Site.
