Field work at the Ascon Landfill Site during the week of March 23 is planned to include:
TO OUR VALUED NEIGHBOR: We are thinking of you and your family as we are all adjusting to the challenges related to the coronavirus. The health and safety of our community and our employees remains our top priority and we’re committed to protecting those around us.
As part of the effort to protect against the spread of coronavirus, we are following the guidance of public health officials. What that looks like for us right now is: support personnel are working from home, project personnel remain on the job to maintain Site critical operations, maintenance, security, and to protect public safety. Those working on Site critical operations are following all recommended best practices guidelines for social distancing, hand washing, and sanitized work spaces.
Our safety commitment to you has not changed: Nothing is more important to our team than the health and safety of the Huntington Beach community. The situation with coronavirus is quickly evolving. We will keep you updated as this situation moves forward and regarding onsite actions.
HAMILTON AVENUE: Traffic barriers were placed on the south side of Hamilton Avenue beginning March 13 to prevent pedestrian and bicycle access adjacent to the 16-foot barrier fence. This action was taken in an abundance of caution due to cracking of the earthen berm parallel to Hamilton Avenue (more information under “Northern Zone” below).
NORTHERN ZONE: Twenty-four hour inspection is ongoing for an unexcavated area of Ascon’s earthen berm parallel to Hamilton Avenue. Future action is anticipated in this area to stabilize the 70-year-old berm. Nine potential berm repair or stabilization options were submitted to DTSC for review and direction.
A reinforced plastic cover is placed over this area in advance of rain, with inspections after rain events. This precaution has been implemented before prior rain events, following the first observation of cracking and notification to DTSC in January.
ONSITE AND OFFSITE: Sampling for the ongoing groundwater monitoring program will be conducted on Thursday, March 26, including at offsite monitoring well locations in the community both north and east of Ascon. This is routine sampling with field professionals briefly opening dedicated monitoring wells to conduct sampling.
Groundwater monitoring is an essential activity during the statewide “stay at home” order issued by the Governor as of March 19. The professionals conducting the groundwater sampling follow guidelines for social distancing, hand washing, and other best practices to ensure their safety and public safety. Results of all groundwater sampling are provided to DTSC.
SITEWIDE: Ascon conducted a stormwater inspection in advance of forecasted rain. Rain-related activity may include pumping out stormwater from onsite some ponded areas to other areas of the Ascon site.
There will be continued inspection and maintenance of stormwater management measures to maintain compliance with Ascon stormwater permit. Stormwater management is subject to inspection by the City stormwater inspector.

SITEWIDE AND OFFSITE: Air quality monitoring continues, both on the Ascon site and at offsite community locations. Air quality monitoring data are posted under the Actively Monitoring Air Quality tab and also on the Ascon Landfill Site web page on the California Department of Toxic Substances Control (DTSC) website, Envirostor.
EASTERN ZONE: Regular inspection of the “Pit F” tent will be conducted.
SITEWIDE: Weed abatement will be conducted as needed throughout the Site as part of stormwater management and fire protection. Plant overgrowth is removed near silt fences as part of necessary weed abatement, leaving roots in place to help prevent erosion.
Equipment used for this work may include:
- Small power equipment, such as a weed wacker or mower
SITEWIDE: Dust and odor mitigation measures continue to be implemented. This includes applying a non-toxic odor suppressant material in excavated and graded zones which forms a hard clay-based shell, covering excavated materials with reinforced plastic covers, and also use of a water truck to mist interior roadways and areas where field work is occurring. Learn more about these ongoing activities and other activities conducted to maintain a safe cleanup project under the Our Safety Commitment tab.
SITEWIDE: Soil sealant will be applied to access and interior roads as a routine dust control action.
HAMILTON AVENUE AND MAGNOLIA STREET: Workers will conduct routine cleanup and removal of trash and debris thrown at and between the concrete base for the 16-foot fence around the outside of Ascon.
SITEWIDE: Supplies needed for ongoing Site maintenance may be expected for delivery.
SITEWIDE: 24-hour onsite security continues.
