Air Quality Monitoring
Dredging occurred between June 6-November 8, 2011.
Click here to view air quality monitoring on the Quality of Life Monitoring Interactive Map. Monitoring was conducted daily during river operations, which have been completed. Daily monitoring at the Processing Facility will continue until all sediment is transported off-site. Phase 2 dredging will resume in spring 2012.

Legend:
Typical Operations: Daily total PCBs under 80% of the standard.
Control Level: Daily total PCBs within 20% of the standard.
Exceedance Level: Daily total PCBs exceed standard.
| Pollutant | Performance Standard | Monitoring Frequency |
|---|---|---|
| PCBs (Residential Areas) | 0.11 micrograms per cubic meter | Continuous Monitoring Daily (24-hour) basis |
| PCBs (Commercial/Industrial Areas) | 0.26 micrograms per cubic meter | Continuous Monitoring Daily (24-hour) basis |
Goal of the Standard
The goal of the air quality performance standard is to minimize the effects on people’s health and the environment from air emissions during the cleanup. Since PCBs are the primary pollutant in the sediment the performance standard, displayed at right, sets the limits for PCBs in the air.
How the Standard Works
- Regular monitoring at multiple locations
- Taking action to minimize air quality effects
- Reporting and notification by the cleanup team to EPA
