Ascon Project Progress
• The Ascon project team and DTSC met in technical exchanges to develop specific work to be piloted onsite to help determine the next steps towards completion of the cleanup. Workplans were approved in April/May 2023 to pilot test Engineered Misting Containment (EMC) and Soil Vapor Extraction (SVE) onsite.
• DTSC is hosting a community meeting, an in-person open house followed by a virtual presentation on Wednesday, May 31. The week of May 8th, a DTSC Community Update was mailed to approximately 10,000 households within a 1-mile radius around the Site and 2,200 Edison High School families. Ascon circulated an eblast to 380 email subscribers with the DTSC Community Update and links to technical explainers on the pilot work. • Pilot work is expected to begin in June and continue through August 2023. • Results from the pilot work will inform the final remediation work and schedule.
Update May 24, 2023, City of Huntington Beach Southeast Area meeting. For Discussion Only.
DTSC Open House, Virtual Community Meeting
Update May 24, 2023, City of Huntington Beach Southeast Area meeting. For Discussion Only.
• The open house is on Wednesday, May 31, at the Senior Center in Central Park, and the virtual (Zoom) meeting will take place that evening.
• Open House: 4–6 p.m.
• Virtual Meeting: 7–8:30 p.m.
• At the open house, information about the Site and the proposed work will be available. DTSC and the third-party technical advisor (Andrew Cherene) will be on hand to discuss the project and answer questions about the Ascon Site history, planned pilot work and next steps.
• The virtual presentation will focus on the planned work and is another opportunity for the community to ask questions.
During the April - May 2020 northwest berm
emergency repair, Ascon used Enhanced Odor
Mitigation (EOM) technologies, including Posi-Shell®
and CupriDyne® Clean, to successfully manage
odors during excavation. These enhanced
technologies were not previously used in work prior
to 2020.
EMC expands upon the EOM technologies by
adding mesh awnings, mesh walls and barrier walls
to minimize the amount of misted odor suppressant
that leaves the excavation area. The EMC method
enables more robust delivery of misted or sprayed
odor suppressants. CupriDyne® Clean being used during north berm emergency repair.
Pilot Test Work:
Engineered Misting Containment (EMC)
Update May 24, 2023, City of Huntington Beach Southeast Area meeting. For Discussion Only.
EMC pilot test work will include:
• Evaluating the capture of odor suppressant mist near the southern Site perimeter using a variety of mist capture configurations
• Ongoing air and odor monitoring at the Site and in the community • Analyzing air monitoring data and observations to confirm the overall effectiveness of odor-reducing strategies
EMC variations planned for pilot testing:
Update May 24, 2023, City of Huntington Beach Southeast Area meeting. For Discussion Only.
Pilot Test Work: EMC
Pilot Test Work:
Soil Vapor Extraction (SVE)
SVE uses a vacuum to remove vapors from the subsurface by drilling a well approximately four inches in diameter into contaminated soils, pulling vapors through the soil and up the well. The extracted vapors are cleaned with granular activated carbon (GAC) through a treatment system above ground, prior to being released to the air.

• This work will occur in parallel with the
EMC and SVE pilot work and is
expected to take approximately two
weeks.
• All concrete to be crushed has been
tested for asbestos, with none found.
• Dust and odor mitigation technologies,
including CupriDyne® Clean and Posi-
Shell®, will be utilized during this work.
• Air quality monitoring onsite, and in the
community, including odor monitoring
within the adjacent neighborhood, will
be ongoing during this work.

Planned Next Steps After Pilot Work
Update May 24, 2023, City of Huntington Beach Southeast Area meeting. For Discussion Only.
Ascon Pilot Work Technical Explainers
• Ascon has prepared technical explainers
as a community resource to provide
information on the odor technologies that
will be tested during upcoming pilot work.
• These explainers are posted on
asconhb.com and have been circulated
to our email subscribers list. We
encourage community members to share
these resources.

Ascon Stormwater Updates
Ascon has received validated results for the four stormwater samples collected in March 2023 (3/15, 3/17, 3/22, 3/23), and the results are posted online on SMARTS.
The validated sample results show that pH and turbidity (clarity of sample) for each of the four samples were within established permit limits.
Concentrations of Site Constituents of Concern (e.g., arsenic, copper, lead, and thallium) were similar to or less than what has been historically sampled. Semi-volatile organic compounds and Polychlorinated Biphenyls were not detected. There were low levels of two pesticides in the 3/17/23 sample collected at the southeast corner and a trace detection of one volatile organic compound (VOC) in the 3/23/23 sample collected at the same location. Ascon does not use these pesticides onsite.
The trace VOC detection in the 3/23 sample was for a compound that is known to be a laboratory contaminant.
Because this compound has not previously been detected in stormwater samples collected at Ascon and no other VOCs were detected in the 3/23 sample, it is suspected that the source of the trace VOC detection in the 3/23 sample is laboratory contamination and not runoff from Ascon.

Continue to circulate invitation and information on the May 31 DTSC community meeting.
Distribute pilot work informational resources through eblasts, weekly Site updates.
Mobilize equipment and crews for pilot work.
