Edison High School is a neighbor of the Ascon landfill located at Magnolia and Hamilton, on the southwest side. Because the school is a neighbor, not an owner or an oversight agency, the District has no authority other than advisement, but shares the concerns of Edison parents and staff as well as community residents regarding potential health threats from the proposed "cleanup" of the waste pits. The health and safety of students and staff are our primary concern, therefore the District has tested the air quality at the school using an independent firm and has received findings that the environmental risk data collected during field investigations are well within safety standards as set by the California Air Resource Board and American Industrial Hygiene Association. In addition, drinking water and the swimming pool have been tested by independent firms with results that are also well within safety standards.
You may know that the operator of the cleanup, Project Navigator, has been ordered by the California Department of Toxic Substances Control (DTSC) to suspend the clean-up until enhanced safeguards are implemented. As a result, cleanup stopped June 7. In a letter from the DTSC, these future safeguards "include measures to address odors emanating from the site onto Edison High School and the nearby community." Mitigation efforts to meet these new required mandates are underway now. The DTSC plans a public meeting before any further clean-up is resumed, and will continue to monitor the air around the school on an ongoing basis.
The District is presently meeting with all agencies involved, including South Coast Air Quality Management District (SCAQMD), DTSC and the City of Huntington Beach, and will review and respond to all actions taken by the parties conducting the cleanup of the closed landfill site as a result of the mandates from regulatory oversight agencies. We will continue to ensure student and staff safety and respond immediately to any recommendations from these agencies.

Additional Precautions Taken on Hamilton Ave and on North Berm
Large equipment and traffic barriers are being delivered today at the Hamilton Avenue gate. Traffic barriers are planned for placement along the south shoulder of Hamilton Avenue adjacent to Ascon.
A condition known as tension cracking is being monitored along the earthen berm parallel to Hamilton Avenue, known as the North Berm. This area of the 70-year-old berm is unexcavated and is approximately 20-feet in elevation from street level. Ascon's technical team considers this area a medium to high risk for potential slope failure, and has instituted 24-hour inspection to track cracking and settlement.

Vandalism of Air Monitoring Trailer Near Eader Elementary School
The air monitoring trailer near Eader Elementary School was vandalized on Thursday, January 23, with equipment stolen and trailer apparatus damaged. Air monitoring personnel contacted the Huntington Beach Police Department, and an officer came to the scene to make a report. The Department of Toxic Substances Control was also notified.
Due to the loss of monitoring equipment and damage to the trailer, no air monitoring data will be available for January 24 until replacement equipment can be obtained and installed. We will post an update when air monitoring at this location resumes.

The installation of a 16-foot barrier fence at the Ascon landfill has begun. The work includes clearing vegetation and existing fencing, and placing temporary fence panels until the final barrier is installed.
Beginning on September 3, traffic will be redirected at the intersection of Hamilton and Magnolia to allow work trucks direct access to the area under construction. This traffic control is under the direction of the City of Huntington Beach, and we expect that the work could impact drivers around the school, particularly around drop off and pick up times. We have been assured that uniformed flagmen will be in the streets ensuring driver safety, and expect the work to take up to eight weeks. The bike lane along Magnolia will be closed during this time, as well as one of the Magnolia southbound lanes.
We are continuously monitoring driver safety around the school and in our student lots, and we will stay aware of any issues related to this work and keep you informed.

The Ascon Landfill Site project is preparing to install a 16-foot high barrier fence along two residential-facing public streets, Magnolia Street and Hamilton Avenue. Construction is scheduled to begin in mid to late July 2019 and continues through late August 2019. This work is being done to provide an additional shield for the community during the excavation phase of the final cleanup of the landfill. For more information, visit the Ascon website.

Representatives from South Coast Air Quality Management District, California Department of Toxic Substances Control (DTSC), Ascon, the Huntington Beach Union High School District, Huntington Beach City Elementary District, the City of Huntington Beach, and the office of Assemblywoman Cottie Petrie-Norris met this week at City Hall.
The parties discussed DTSC's required health and safety enhancements at the Ascon landfill site to control odors, including tenting, as well as additional safety testing being planned.
A schedule for all future action on the site is expected in the next few weeks, which will be posted on the Ascon website. A 16 foot barrier fence along parts of Hamilton and Magnolia streets, across from Edison High School, will be constructed as part of this schedule. Currently, a landscape cleanup is in progress to prepare the site's perimeter for the barrier fence, which is not part of the mitigation work.
The agencies agreed to meet regularly to discuss upcoming plans, address concerns, and ensure effective communication strategies aimed to keep the neighboring community informed. We will keep parents and staff updated through this website, with links to the Ascon plans and schedules as they are approved.
