Cleanup and Abatement Order R6T-2022-(PROPOSED) for Big O Tires

The Lahontan Water Board intends to issue Cleanup and Abatement Order Number R6T-2022-PROPOSED (proposed CAO) within the year. The proposed CAO names David and Kathleen Barnett, CAD Enterprises LLC, CAMCO, and Lightning II as “Dischargers” and orders cleanup of discharges of solvent wastes from the former Big O Tires (Site). The discharges have resulted in violations of prohibitions contained in the Water Board’s Water Quality Control Plan.

The proposed CAO is being issued to assess, cleanup and abate discharges originating from the Site. The Lahontan Water Board previously issued an Order to Submit Technical Reports in Accordance with Section 13267 of the California Water Code on May 10, 2019, to investigate and cleanup contamination originating from the Site. The proposed CAO requires the Dischargers to (1) Develop and Submit a Conceptual Site Model, (2) Prepare and Submit a Sampling and Analysis Plan, (3) Develop, Submit, and Implement a Site Assessment Work Plan(s) to Assess, Characterize and Delineate the Extent of Wastes in Soil, Soil Vapor, and Groundwater, (4) Prepare and Submit a Human Health and Ecological Risk Assessment, (5)Conduct Remedial Actions, (6)Public Participation, and (7) Conduct Groundwater Monitoring. These actions are needed to protect human health and the environment, and existing and potential beneficial uses, including the restoration of the drinking water aquifer for human consumption.
