125 S. San Marcos Road Contaminated Soil Excavation

The project involves the excavation, loading, and hauling of up to approximately 1,750 cubic yards of arsenic-contaminated soil from the Tatum Property in Santa Barbara, California, with strict measures in place to control environmental exposure. Stockpiles of contaminated soil will be covered with continuous heavy-duty plastic sheeting or treated with Soil-Sement, a soil binder designed to suppress fugitive particulates and Reactive Organic Compound emissions. All transported soil will be moved using covered dump trucks to prevent airborne release during transit. The Santa Barbara County Air Pollution Control District is the contracting agency overseeing compliance with local air quality regulations, ensuring that all excavation activities align with permitted protocols to minimize emissions. Environmental Health Services Site Mitigation Unit holds primary authority for soil investigation and cleanup under the approved Corrective Action Plan and has authorized the work, while the County of Santa Barbara serves as the Lead Agency under CEQA for the broader Tatum Multifamily Housing Development Project. The contract is forecasted under the title 125 S. San Marcos Road Contaminated Soil Excavation, with Carly Barham, Air Quality Specialist, listed as the primary point of contact for inquiries regarding permit compliance and operational details. Ron Wu from RTACQ serves in a secondary advisory role. The work is scheduled for execution following the projected posting date of June 24, 2026, and is confined to the specific parcel identified by APN 065-040-026. All activities are designed to meet both regulatory standards for hazardous material handling and the district's air quality requirements, emphasizing containment, emission control, and environmental protection throughout the excavation, transport, and disposal phases.
