DTSC approved an air monitoring pause for Memorial Day to allow our air quality professionals to be with their families. The brief pause is from approximately 7 a.m. on Friday, May 26 through approximately 7 a.m. on Tuesday, May 30.
Where to find 24/7 air monitoring data and live stream weather: Sitewide and neighborhood air monitoring data and live streaming weather conditions from the Ascon site are found on the Actively Monitoring Air Quality page on asconhb.com. Analytical data are first analyzed by a certified outside laboratory, then validated, and then submitted to DTSC and shared on their online document database, Envirostor. To view archived air monitoring results posted by DTSC on Envirostor — including weekly field inspections by DTSC that include air monitoring observations — click on “Community Involvement Documents” and scroll to “Updates and Information.”

DRONES: Drone flights over Ascon can create worker and Site safety issues. Please don’t fly drones over sensitive onsite equipment and the power lines along the perimeter of Ascon. We appreciate the community’s assistance.
ENTRANCE AND EXIT GATES: Entering the Ascon site is prohibited to those who are not authorized. The community is asked to keep a safe distance from both entrance and exit gates at Ascon, and refrain from parking, walking, or standing in these areas. The gates on Magnolia Street and Hamilton Avenue may open unexpectedly for workers conducting air monitoring and site inspections, as well as supply delivery and removal.
PEDESTRIANS: Your safety is important! Pedestrians have been observed walking next to Ascon along Magnolia and Hamilton streets (adjacent to the concrete fence base where there currently is no sidewalk). We encourage pedestrians to observe public pathway signage and use the sidewalks on the east side of Magnolia and the north side of Hamilton.
