Air monitoring continues 24/7 both on the Ascon Site and at community locations, which includes dust data at upwind (offsite sources) and downwind stations on the Ascon Site documenting effective dust control measures.
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. 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 quality checks — click on “Community Involvement Documents” and scroll to “Updates and Information.”

DRONES: The community is asked to not fly drones over the Ascon when there is active work. This could create worker and Site safety issues. We appreciate the community’s assistance by preventing drone flights over sensitive onsite equipment and the power lines along the perimeter of Ascon.
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 next 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.
PHYSICAL DISTANCING: Work at Ascon is being conducted under Site safety protocols regarding COVID-19 and ongoing protocols and procedures to maintain job safety. These practices apply to air quality professionals and other team members who may be outside the fence conducting work. 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.
