Air monitoring continues 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 Pit F telemetry air monitoring data: As the Pit F active work and final demobilization actions are completed, the near real-time air monitoring has been paused. The Pit F Telemetry Air Monitoring data and webpage are in the process of being archived for the public on the asconhb.com website. The 24/7 air monitoring onsite and offsite continue
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 submitted to DTSC and shared on their online document archive, Envirostor. To view archived air monitoring results posted by DTSC on Envirostor, click on “Community Involvement Documents” and scroll to “Updates and Information.”
DRONES: The community is asked to not fly drones over the Ascon Site and over the Pit F tent during this work. This could create worker and Site safety issues. We appreciate the community’s assistance by preventing drone flights over the occupied tent structure, sensitive equipment onsite, tall equipment such as cranes, and moving vehicles and workers conducting work onsite, as well as the power lines along the perimeter of Ascon.
ENTRANCE AND EXIT GATES: 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 departing vehicles during Pit F demobilization. There will be a flag person at the gate when vehicles are departing through the demobilization phase of Pit F, as a public safety practice.
PEDESTRIANS: 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 use the sidewalks on the east side of Magnolia and the north side of Hamilton to avoid walking near or in front of entrance and exit gates.
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.
