DID YOU KNOW?

The Department of Toxic Substances Control (DTSC) has approved pausing portions of Ascon’s onsite air monitoring while there is no active earthwork. This pause began Friday, February 23, 2024. Monitoring of total VOCs and PM10 dust will be conducted onsite during this inactive phase, as will weekly reporting. Both onsite and offsite sampling will resume when work restarts at the Site.

Air quality monitoring data consistently shows air quality has been safely below health-protective screening levels, including during active work. Air monitoring data collected both on and offsite is available on our Actively Monitoring Air Quality webpage. We will continue to keep the community updated as we work towards the remediation restart.

SITEWIDE ACTIVITIES

  • MAINTENANCE: Regular maintenance and stormwater management is being conducted within the Site and around the perimeter fence areas, including gate areas.

  • INSPECTIONS:

    • DTSC is the lead regulatory agency for the Ascon project and conducts regular inspections at Ascon and independent air monitoring checks in nearby neighborhoods. Their inspection reports can be found on the online DTSC database, Envirostor.
    • The City of Huntington Beach continues its regular stormwater inspections of Ascon. Ascon remains in compliance with stormwater pollution prevention requirements.
    • 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. Active mitigation measures by Vector Control are protective of the community, as well as onsite workers, to prevent mosquitoes.

  • SECURITY: 24-hour onsite security continues. Security is not always visible at the entrance gates. In addition to 24/7 onsite security, there are regular visits by air quality technicians, Site inspectors, and Site maintenance personnel. Unannounced visitors without official business or agency oversight of Ascon are not permitted to enter the Site. Trespassers will be reported to the Huntington Beach Police Department and DTSC.
