During its November 4-5, 2026 board meeting, the Lahontan Water Board may consider Cleanup and Abatement Order Number R6-2026-PROPOSED (2026 Proposed CAO) for the Lake Tahoe Laundry Works. The Advisory Team recently proposed a schedule for document review and public comment for the 2026 Proposed CAO after being informed of a stalemate in confidential settlement negotiations. Further instructions to interested parties as to the public comment period are planned on or before July 3, 2026 by the Advisory Team.

Fast Facts

  • It is proposed to clean up and abate the regional perchloroethylene (PCE) groundwater plume originating from the Site.
  • The current draft is built from previously issued final and proposed draft CAOs.
  • It names Seven Springs Limited Partnership, Fox Capital Management Corporation, Bobby Pages, Inc. and Connolly Development, Inc. as “Dischargers”
  • It orders cleanup of discharges of solvent wastes from the former Lake Tahoe Laundry Works (Site).
  • It describes discharges that have violated prohibitions in the Water Board’s Water Quality Control Plan and impacted local public drinking water sources.

Additional History

The Lahontan Water Board previously issued Cleanup and Abatement Order R6T-2017-0022 on May 12, 2017, to investigate and cleanup contamination originating from the Site and evaluate the Site’s contribution to the regional PCE groundwater plume. On June 16, 2022, the Cleanup Team provided Cleanup and Abatement Order R6T-2022-Proposed (2022 Proposed CAO) for consideration. The 2022 Proposed CAO required cleanup and abatement of the regional PCE groundwater plume after data did not indicate separation between the Site and the regional PCE groundwater plume. The Cleanup Team circulated the 2022 Proposed CAO and received public comments. On August 17, 2023, the Cleanup Team provided the Markup of R6T-2022-Proposed and the Response to Comment documents (2023 Revised CAO). The 2023 Revised CAO included consideration of all comments received on the 2022 Proposed CAO and, where appropriate, proposed revisions.

Prior to the consideration of the 2023 Revised CAO by the Lahontan Water Board, the “Performing Parties” expressed to Lahontan Water Board Cleanup Team staff that they would like to pursue settlement negotiations regarding the issues raised in the 2023 Revised CAO. These settlement negotiations involve the “Performing Parties”, Lahontan Water Board Cleanup Team, Lukins Brother Water Company, and Tahoe Keys Water Company. On April 3, 2026, the Cleanup Team informed the Advisory Team of a potential stalemate. On April 8, 2026, the Advisory Team indicated that the Lahontan Water Board will consider a cleanup and abatement at the November 4-5, 2026 board meeting. The Advisory Team further requested “markup” documents which show the potential changes between the 2022 Proposed CAO and 2026 Proposed CAO. The Cleanup Team provided the requested documents on June 26, 2026.

Highlighted changes and requirements

The 2026 Proposed CAO has been updated from the 2023 Revised CAO. The 2026 Proposed CAO now includes (1) a new Executive Summary and (2) data collected since 2023. The Executive Summary describes the procedural history of the 2026 Proposed CAO and relevant court rulings after El Dorado County Superior Court’s remand of the 2017 CAO which apply to the Order. The updated data includes additional SCAP Regional PCE Contamination activities, routine groundwater monitoring, and on-Site remediation system operational data. The updated data does not change any interpretations or conclusions with respect to the Site’s contribution to the Regional PCE Contamination as described in the 2022 Proposed CAO.

The 2026 Proposed CAO requires the Dischargers to (1) Develop and Submit a Conceptual Site Model, (2) Prepare and Submit a Sampling and Analysis Plan and Quality Assurance Project Plan, (3) Develop, Submit, and Implement Site Investigation Work Plan(s), (4) Develop, Submit, and Implement a Monitoring Well Installation Work Plan, (5) Develop, Submit, and Implement a Vapor Intrusion Investigation Work Plan, (6) Prepare and Submit a Human Health and Ecological Risk Assessment (HHERA), (7) Conduct Remedial Action, (8) Prepare and Submit a Public Participation Plan, and (9) Conduct 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.
