Under DTSC oversight, waste material from Pit F was Jessica.Anderson65Wtsc.ca.gov
successfully excavated and removed from the Ascon _
Site. The excavation of the former Pit F was
completed in 31 days of work and included
excavation of approximately 2,600 cubic yards of r, -.
waste material. 258 truckloads of waste were Ar - -per■
transported to a permitted state landfill in Central
California. This work was performed with approvals
and permits from several agencies, including DTSC ems.
and the SCAQMD. Air monitoring was conducted for

The tent was cleaned, dismantled, and removed from the Ascon Site. Remaining soils in the former
Pit F area were sealed following active work with a hardened cement-like slurry material between
two to three feet thick and then covered with Posi-Shell®, a clay-based sealant that dries to form a
hard crust to prevent soil erosion.
The removal of Pit F waste was a key step towards completing the future remediation at Ascon and
as a part of the final remediation, this area will be covered by an engineered cap which is explained
in the Remedial Action Plan (RAP) on Envirostor. To learn more about the Pit F excavation work,

Milestones and Current Status of Ascon
• Perform ongoing community air monitoring in neighborhood and school locations to establish an
offsite baseline of air data.
• Completed emergency repair of the North Berm slope parallel to Hamilton Avenue to ensure
public and environmental safety.
• Established a near-real time air monitoring telemetry system for use during active onsite work,
with ongoing data posted on the project website.
• Completed Pit F excavation, removal, and demobilization work.
• Completed a Sitewide Odor Assessment analysis to inform future odor management at the Site.
• Conducted winterizing measures for the 2021-2022 wet season following stormwater best
management practices.
• Increased community outreach, with comprehensive project website, weekly Site activities
updates, explainers on technical topics, and ongoing air quality monitoring results with live-
streaming weather data.
• Introduced AsconAlert, an opt-in notification system that can send emergency and informational
notifications to the community via text or email.

Next Steps at Ascon
Before the start of final cleanup at the Ascon Site, DTSC is reviewing an interim work proposal for
the Site. The work will include construction of an unpaved internal access road, crushing onsite
concrete, and transporting the crushed concrete to the northern area of the Site. The concrete is to
be reused as a cover over a woven geotextile fabric to form a reinforcement layer over the lagoon
that will enable construction of the engineered cap.

Why is this work being done?
The excavation and removal of waste materials in Pit F is a key step in completing the
remediation of the Ascon Site. The Pit F work is discussed in the DTSC-approved Remedial
Action Plan (RAP), Environmental Impact Report, Remedial Design Report, and Remedy
Implementation Plan.
When is this work taking place?
This remedial work is scheduled to start in June 2021 and continue through August 2021.
Workers will be arriving at the site as early as 6 a.m. for daily worker safety briefings, with work
taking place Monday through Friday 7 a.m. — 6 p.m., and Saturday if required. Waste haul
trucks may arrive prior to 7 a.m. and will stage inside the Ascon site. Security guards will be
present at Ascon 24/7 with nighttime patrols. Pit F equipment monitoring personnel will be
present during night hours.
What safety measures are in place?
Work will take place within the Pit F tent in a vacuum environment, in which a blower system
pulls potential odor and VOCs into an air treatment system. The air will be treated with carbon
filters that will trap and hold the contaminants. This air treatment system is included in the
permit from SCAQMD for the Pit F work.
A multi-layered air monitoring network will monitor air quality in the work zone, around the Site
and in the surrounding neighborhood. In addition to 24/7 air monitoring conducted at the
perimeter of the Site and at neighborhood stations, a telemetry-based air monitoring network
will collect additional data during work hours. Air quality data will be posted to the Ascon
website at asconhb.com/air-monitoring.

Odor Assessment Field Investigati
Ascon Landfill Site g0'1

.r�
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.
The onsite and offsite air monitoring, since January 2019, has shown that air quality data has been below
health-protective screening levels.
What is the purpose of the Odor Assessment Analysis?
The odor assessment will identify areas of the Site that may
N have the potential to generate odor, collect information on
Hamilton Ave odor characteristics, concentration, and identify specific
compounds. This investigation will provide additional
technical data as part of the final evaluation of the feasibility
of odor management technologies. Better understanding the
actual odor driving compounds and where they are
Q concentrated on the Site will provide invaluable knowledge
a to better manage odors at the Site during future work.
N How will this work be conducted?
ASCON SITE A team of up to 20 people will be at the site for the duration
of the work. A series of borings will be established in a grid
across the Ascon Site in the remaining areas planned for
excavation. Each boring will be advanced to the planned
excavation depth. The samples will be collected using direct-
push or hand augering methods. The field investigation work
is not expected to generate odor. Air quality technicians will
Sampling to be conducted be present during sampling. Samples will undergo a
in future excavation areas chemical analysis and/or professional odor panel testing to
describe the odor, determine concentration, and help map
areas that have the potential to generate significant odors.
A Public Hotline, (714) 388-1825, has been established by the Ascon project team to ensure questions or
concerns from the public can be addressed promptly. Calls received by the Ascon project team and their
responses are documented and shared with the DTSC.

Department of Toxic Substances Control
Why is this work being done?
The community raised concerns about odors. The Ascon project team conducted a localized odor assessment
during the north berm emergency repair work in spring 2020 to gather more information about potential odor
causing compounds in that area of Ascon. Gathering this type of information across the Site provides critical
information to better inform future work and address concerns raised by community members.
When will this work take place?
The field investigation is anticipated to begin in mid-January 2021. The duration of the field investigation is
expected to be up to three months between the hours of 7 a.m. and 6 p.m.
Milestones and current status of Ascon
Since the work suspension in June 2019, all directed investigations and enhancements have been completed
including:
• Construction of a barrier fence along Magnolia and Hamilton streets with an interim fence at the
intersection.
• Independent field investigations confirming no evidence of asbestos.
• Additional community air monitoring to establish an offsite baseline of air data.
• The use of new odor suppressant products.
• The Ascon project also funded a third-party technical advisor, managed by the City of Huntington Beach
and independent of the project and DTSC, to respond to community questions.
The odor assessment is part of the analysis for the feasibility of additional odor management proposed by
ASCON. Details of the odor management plan and schedule to restart the remaining cleanup will be more
certain later in 2021.
