UPDATE as of January 25, 2021
The Department of Toxic Substances Control (DTSC) has approved a site-wide odor assessment at the Ascon Landfill Site. The purpose of the assessment is to identify areas of the Site that may have the potential to generate odor during future cleanup work at Ascon. The assessment work will begin in mid-January 2021 and will consist of collecting and analyzing soil and soil vapor samples in the areas of the Site that are planned for future excavation.

Huntington Beach residents have expressed significant concerns about the clean-up efforts going on at the long-closed Ascon Landfill site at the SW corner of Magnolia and Hamilton. Even though the City is not regulating this clean-up effort, many residents have attended Council meetings and other meetings, have asked questions and expressed concerns on social media, and have sought more information about community safety.
We at the City of Huntington Beach are concerned, too. The site needs to be cleaned, but cleaned in a manner that protects our residents and the many school children, parents, and teachers at neighborhood schools. More needs to be done by DTSC and the Ascon operators to assure us that the site clean-up activities are safe for all of us.
This section of our web page is intended to help our residents become more familiar with the site, the clean-up activities, the agencies that are overseeing the clean-up, and what residents can do to share information, ask questions, and express any concerns.
3rd Party Technical Advisor!
In an effort to help local residents understand the environmental cleanup process being conducted by Ascon at the landfill site, the City has hired Andrew Cherene with HDR to act as an independent, third-party technical advisor to any resident who may have questions about the cleanup. As part of our continued effort in transparency and ongoing outreach effort in addition to assisting residents to better understand the complicated science with the clean-up work, residents may submit Ascon questions directly to Andrew.

The Site and the Clean-Up Effort. According to the clean-up EIR, the Ascon Landfill was an active landfill operated between 1938 and 1984. Industrial and oil field wastes were disposed at the landfill from 1938 to 1971. After 1971, construction debris was disposed at the Site until it was closed in 1984. The Site contains various types of liquid and solid waste in buried pits, surface piles of concrete, rebar and other construction debris, and fenced, open lagoons (ponds).
The Site has undergone several changes of ownership and environmental investigations since 1984. In 2003, DTSC and some of the Ascon Landfill Site Responsible Parties (RPs) entered into a Consent Order with the State of California for the Site’s cleanup. Preliminary remediation work began in July 2017, and has continued with full-scale remediation starting earlier in 2019.
The Agency Overseeing the Clean-Up. Site cleanup is directed by the State of California’s Department of Toxic Substances Control (DTSC), which is a department within the California Environmental Protection Agency or Cal-EPA. DTSC has oversight over the final cleanup, including monitoring the work and mitigation measures, and providing community information. The City of Huntington Beach is not overseeing the clean-up, nor are we issuing permits for it.
Our Concerns, Community Concerns. The City has been concerned about the full-scale remediation, especially after hearing from area residents about dust and odors from the activities. As those concerns started coming in to us, we have been working with DTSC, the South Coast Air Quality Management District, and others on this important issue. Our concerns include:
How can I find out more? General project information can be found at www.AsconHB.com and at www.Envirostor.dtsc.ca.gov. We encourage you to contact them directly at [email protected] and [email protected].
The Ascon remediation group will work with DTSC, the City of Huntington Beach, South Coast Air Quality Management District (SCAQMD) and the Huntington Beach Unified High School District (HBUHSD) regarding actions directed by DTSC, which include:
What’s the latest information? Currently, the clean-up effort is stopped, as DTSC works with the Responsible Parties (RP) on a checklist of items that DTSC believes need to occur before clean-up can start again. A June 12, 2019 letter that DTSC sent to the RP is here. Please take a look at it, including the last page. As you can see from the letter, DTSC is recommending looking at a tenting system, increasing the height of the fencing, coverage of soil, additional air quality monitoring, and more. The remediation is not to start up again until DTSC has signed off on these “health and safety enhancements."
What if I have questions? A 24-hour NON-EMERGENCY public hotline has been established by the Ascon Landfill Site project team to ensure questions or concerns can be answered promptly. DTSC receives documentation of the calls made to the project hotline. The Ascon Landfill Site hotline number is 714-388-1825.
