Noise Monitoring
Dredging occurred between June 6-November 8, 2011.
Click here to view noise monitoring on the Quality of Life Monitoring Interactive Map. Monitoring was conducted daily during dredging operations. Phase 2 dredging will resume in spring 2012.

Legend:
Typical Operations: The noise level is in compliance with the control level and standard.
Control Level: Noise levels are above the control level.
Exceedance Level: Exceedance of the noise standard.
| Location | Performance Standard | |
|---|---|---|
| Short-term | ||
| Residential (nighttime) | 65 decibels | |
| Residential (daytime) | 75 decibels (control level)* 80 decibels |
|
| Commercial/Industrial (daytime and nighttime) | 80 decibels | |
| Long-term | ||
| Residential (daytime and nighttime) | 65 decibels | |
| Commercial/Industrial (daytime and nighttime) | 72 decibels | |
| *Control level is the level at which measures are recommended or required | ||
Goal of the Standard
The goal of the standard is to minimize the effects of noise from the project on the quality of life in the surrounding communities.
What is the Standard?
During Phase 2, the performance standard for noise requires monitoring the sources of noise from the cleanup at the beginning of any operations that could result in increased noise levels compared to Phase 1 operations or compared to previously implemented in Phase 2, or in response to complaints. It establishes standards for short-term operations (construction, dredging, and backfilling) and long-term operations (sediment processing/transfer facilities). The standards vary depending on the time of day (daytime or nighttime) and whether the noise occurs in a residential or commercial/industrial area. The performance standard, displayed at right, sets limits on noise.
How Does the Standard Work?
- Monitoring occurs at the beginning of any operations that could result in increased noise levels compared to Phase 1 operations or compared to previously implemented in Phase 2, or in response to complaints.
- Receive, investigate and respond to complaints
- Take action to minimize noise
- Reporting and notification by the cleanup team to EPA
