Field work at the Ascon Landfill Site during the week of June 22:

EASTERN ZONE: Maintenance and repairs of the “Pit F” tent (near Magnolia Street) will be conducted. This work is expected to start Monday, June 22, and the anticipated duration of the work is three to five days.

You may see:

  • Workers at various elevations next to the walls and top of the Pit F tent, using a man lift and hand tools.
  • You may hear a periodic back up alarm when the man lift is moved, which is an important safety measure for our onsite workers.

SAFETY MESSAGE: Work at Ascon is being conducted under Site safety protocols regarding COVID-19. These practices also apply to air quality professionals and other team members who may be outside the fence conducting work and at air monitoring locations in the community. We ask for the community’s support of these safety practices by maintaining physical distancing to allow these professionals to focus on their work and stay safe.

SITEWIDE: Regular inspections are conducted by Orange County Vector Control of the onsite detention basins and other areas of the Ascon site where water may be detained. These inspections are typically conducted monthly. Active mitigation measures by Vector Control are protective of the community, as well as onsite workers, while preventing mosquitoes and other pests.

SITEWIDE: Stormwater management is subject to inspection by the City stormwater inspector. Ascon conducts stormwater inspections in advance of forecasted rain as an ongoing essential activity which continues under the current State Executive Order. There will be continued inspection and maintenance of stormwater management measures to maintain compliance with Ascon’s stormwater permit.
