SITEWIDE ACTIVITIES
MAINTENANCE: Regular maintenance will be conducted within the Site and around the perimeter fence areas. Workers and equipment will be in the southeast area of the Site installing sound mitigation panels.
You may see: Workers will conduct minor grading in select onsite areas for sound mitigation features and as part of Pit F excavation work preparations.
PIT F EXCAVATION PREPARATIONS: Workers inside the large white tent on the east side of Ascon near Magnolia Street are preparing for excavation of Pit F. The air treatment system, which will operate 24/7 during excavation, may be turned on and off as sound mitigation is completed. Site security continues 24/7 and personnel that monitor Pit F equipment and systems will be on location overnight.
You may see: You may see flashlights or headlights from a limited number of vehicles at night conducting inspections and providing security at the 38-acre Site. Workers, materials, and large equipment, like manlifts, small cranes, water trucks, forklifts, materials storage bins, may be arriving or be removed from the Site. This includes turning on equipment like the air treatment system for operational checks.
You may hear: A low-level hum for the air treatment system, which has been mitigated with 20-foot and 8-foot sound panels and sound blanketing in addition to the 16-foot sound wall along Magnolia Street. This is tested to confirm compliance with local ordinances for residential areas. This system is required to operate 24/7 during the duration of Pit F work to maintain a vacuum environment and treat air inside the tent for workers and our neighbors. You may hear periodic sounds during work hours, like vehicle backup signaling required for worker safety. Workers will minimize backing up vehicles when possible and when it is safe for workers and equipment.
SECURITY: 24-hour onsite security continues. Security is not always visible at the entrance gates. The Ascon security personnel patrol within the Site conducting nighttime patrols of the 38-acre property, and also provide gate security during work hours. In addition to 24/7 onsite security, there are regular visits by air quality technicians, Site inspectors and Site maintenance personnel. During Pit F active work there is overnight equipment monitoring personnel onsite.
