Onsite Pilot Work Telemetry Air Monitoring
A telemetry air monitoring system is collecting near real-time data during working hours while Ascon tests two odor mitigation technologies onsite, Engineered Misting Containment (EMC) and Soil Vaper Extraction (SVE). Work hours are from 7 a.m. to 6 p.m., Monday through Friday.
Telemetry-based air monitors around the active work areas capture air monitoring data in near real-time. The telemetry network records total volatile organic compounds (VOCs) and dust data upwind and downwind of the work area. Site contributions, concentrations detected downwind of the work area excluding upwind or background, are displayed and compared to the Site action levels, confirming air concentrations are below action levels.
If a brief telemetry reading is above an action level it does not mean that there was a harmful exposure or that the community’s health is at risk. Air monitoring action levels are used during the work at Ascon to guide mitigation actions, stop work actions, and prompt increased actions to control potential odor, emissions, or dust. For the purposes of evaluating potential community exposures air data are evaluated over 24-hour periods and longer. The air data are submitted to the California Department of Toxic Substances Control (DTSC), available for review by the South Coast Air Quality Management District (SCAQMD), and shared on our Actively Monitoring Air Quality webpage.
