What is the Emergency Repair Work?
The Department of Toxic Substances Control (DTSC) will oversee the emergency repair work to an
earthen berm at the Ascon Landfill Site scheduled to start on April 20, 2020. This partially excavated
berm runs parallel to Hamilton Avenue at the northern portion of the Site across from the Edison
Community Park. Work will be conducted under a managed excavation, utilizing an excavator with a long-
reach bucket and onsite transport or dump trucks. Soil will be removed from the top of the berm in
incremental amounts and moved to treatment areas within the interior of the Site, with continual
application of odor and dust suppressants. Removal of this soil will flatten the berm, reduce the weight on
the berm, and the risk of the berm failing and the potential of soils sliding onto Hamilton Avenue past the
barrier fence. The work will be conducted with appropriate safety measures in place.

Concern
DTSC continues to work with the Huntington Beach
Union High School District, Huntington Beach City
School District, South Coast Air Quality
Management District, City of Huntington Beach,
and the California Department of Public Health to
listen and respond to public health concerns that
are communicated to DTSC. Edison High School and
Eader Elementary School continue to be safe.
A Public Hotline, (714) 388-1825, has been established for this work by the Responsible Parties to ensure
questions or concerns from the public can be addressed promptly. This is not an emergency number.
Calls received by the Ascon project team and their responses are documented and shared with DTSC.
Emergency calls should be directed to 911.
Why Conduct the Emergency Work Now?
Regular inspections have identified stress cracks in the berm that indicate the potential for soils to slough
off or slide down into the barrier fence or potentially onto Hamilton Avenue, creating a public safety
hazard. Recent and upcoming rains further increase this risk, so prompt action is warranted. In the
interim, a 24-hour geotechnical monitoring and alert system is currently in place, and regular physical
inspections are conducted as an early warning system in the event the slope condition worsens before
the emergency field work is done.
Will Community Members Be Protected?
Yes. All work will be conducted with the utmost care for the safety of the community and on-site workers.
To minimize dust and odors, several tested applications, including new products now in use at Ascon, will
be utilized. Air quality professionals will be monitoring and reporting on air quality throughout the duration
of the work. Air monitoring and sampling will be performed in compliance with requirements approved by
DTSC and the South Coast Air Quality Management District (SCAQMD).

Quality. Look for the link to Monitoring Air Quality During Remedial Fieldwork on the bottom right of
the page.
When Will the Emergency Work Be Conducted?
Work will begin on April 20, 2020 and conducted between 7:00 a.m. to 6:00 p.m. There will be regular
updates on AsconHB.com as the work proceeds. This work is expected to take between two to five
weeks. The duration can change due to unforeseen weather events or above-and-beyond actions to
prevent dust and odor for the community.
