1. What is the Ascon Landfill Site?

    The Ascon Landfill Site is a 38-acre property located at the southwest corner of Magnolia Street and Hamilton Avenue in Huntington Beach. It was utilized as a licensed facility from 1938 to 1984, when the landfill was closed.

  2. What was dumped at the Ascon Landfill Site?

    The landfill originally received drilling waste from oil production in the Huntington Beach area, during the region’s oil boom. Industrial and oil field wastes were disposed of at the landfill until 1971. From 1971 to 1984 construction debris was disposed of at the site. The landfill was closed in 1984.

  3. Who is responsible for the cleanup?

    The original owners of the property who started the landfill in 1938—the Garrish Brothers—and the subsequent owners are no longer able to participate in the cleanup. In 2003, the State of California and Cooperating Parties, known as Responsible Parties, entered into a Consent Order to clean up the landfill. The Responsible Parties never owned the landfill, but had predecessors who utilized the landfill.

    No public funds or tax dollars are used for the cleanup. The cleanup is funded by the Responsible Parties, including costs for oversight by the California Department of Toxic Substances Control (DTSC).

  4. Has anything been done since the landfill closed?

    Since the 2003 Consent Order, there have been three major remedial work efforts that have significantly changed the physical nature of the landfill through removal of over 160,000 tons of waste materials.

    These remedial actions include the Emergency Action (2005-2006), the Interim Removal Measure (2010-2011), and the Early Remedial Action and Lagoon Solidification (2017-2018). Information about those remedial actions is available on this website and on DTSC’s Envirostor.

  5. When does the work start?

    The Final Remedy is anticipated to mobilize in January 2019, with some deliver of equipment or materials and minor Site preparation work in December 2018.

  6. Who oversees this work?

    The work is conducted under a Work Plan and remedial design approved by DTSC, which also certified the Final Environmental Impact Report (EIR) and approved the Remedial Action Plan (RAP) in June 2015 after public review and comment.

    Additional permits for aspects of the field work are obtained from the South Coast Air Quality Management District (SCAQMD), California Division of Oil, Gas and Geothermal Resources (DOGGR), Huntington Beach Fire Department and the City of Huntington Beach, who also approves the coastal zone work on behalf of the California Coastal Commission.

  7. What happens when the Final Remedy is done?

    We anticipate this work will be completed in mid-2020. After the construction of the environmental cap in the final phase, the property will be planted with drought tolerant vegetation native to California, and the permanent perimeter fence will be installed.

    The companies involved in the cleanup and the companies who own the property are still responsible for monitoring the site after the cleanup is completed. They will provide ongoing maintenance and Site security after the project is completed.

  8. Will the Ascon Site be developed?

    There are no immediate development plans. Any future development consideration would be a separate and public Environmental Impact Review process before the City of Huntington Beach, with DTSC certifying allowable uses.

  9. Where can I find more information?

    The fact sheets and documents for the work conducted at the Ascon Landfill Site are available on this website and on the DTSC website, Envirostor.
