The two air monitoring programs at Indiana Harbor & Canal (IHC) Confined Disposal Facility (CDF) collect data, establish safety levels, and develop protocols to ensure that possible airborne emissions from the CDF and dredging activities are safe.
Ambient Air Monitoring
Collects long-term air quality data at the CDF and in the surrounding community, and assesses the impact of weather and seasonal variations on air quality data
Note: In July 2021, USACE began the Phase 2 dike project to expand the CDF exterior dikes by 11 feet to maintain sufficient storage capacity for the intended project life, consistent with the original project authorization and plan. Dredging is not being performed while construction is underway. As a result, PID monitoring and turbidity monitoring are on hold. Real-time air monitoring continues in temporary locations off dike at onsite northeast and southeast stations using the M1 and M2 monitors (AM1 and AM2). The M3 and M4 monitors are not operating during dike expansion. Ambient air monitoring continues in one southwest location off dike (CON-SOUTH) and at the school. Dredging activities are anticipated to resume in 2024. More information »
5 stations during dredging: 4 on the CDF perimeter (North-CDF, East-CDF, South-CDF, and West-CDF) and 1 at the East Chicago High School
2 stations during dike construction: 1 off dike (Construction-South) and 1 at the East Chicago High School
5 stations during dredging: 4 on the CDF perimeter (M1-M4) and 1 photoionization detector (PID) near the off-loadingbarge 2 stations during dike construction: 2 off dike (AM1, AM2)
Monitors
