The Department of Toxic Substances Control (DTSC) is overseeing soil sampling at the Ascon Landfill Site, in order to proceed with completion of the corner of the 16-foot barrier fence near the intersection of Magnolia Street and Hamilton Avenue. During future activity, about 100 cubic yards of soil will be excavated at the northeast corner of the Ascon site to install the 16-foot barrier fence. This is required due to the limited space between the existing earthen berm and the traffic signal at the southwest corner of the Hamilton Avenue and Magnolia Street intersection. The majority of the 16-foot barrier fence is already installed along Hamilton and Magnolia streets.
Soil Screening:
Before the future soil excavation activity to complete the fence, a soil screening investigation will be conducted in the earthen berm to confirm the nature of the materials, screen for total Volatile Organic Compounds (VOCs), and the potential for the materials to produce odor. Samples will be collected via hand-auger borings in nineteen locations. Laboratory samples collected will undergo data validation and quality control and in accordance with the U.S. Environmental Protection Agency’s Test Methods for Evaluating Solid Waste: Physical/Chemical Methods.
Air & Dust Monitoring:
Air monitoring for VOCs and dust will be conducted, both in the immediate area of the soil investigation work and at perimeter locations. Wind direction and wind speed will be recorded throughout the duration of this activity with an on-site meteorological station. Ascon site meteorological data is live streaming on Weather Underground at https://www.wunderground.com/dashboard/pws/KCAHUNTI165. The earthen berm will be watered prior to the soil investigation and the work will include active dust mitigation. No odor is anticipated, however, odor mitigation materials will be utilized if needed.
Work Notice:
Sampling activities will begin the week of October 28, between 7 am and 6 pm, and are expected to be completed within four (4) days. There will be no street or lane closures.
