Phase 1 Noise Monitoring

The monitoring data on this page reflects performance standard monitoring collected during Phase 1 dredging. Phase 1 dredging occurred from May 15, 2009 to October 26, 2009 and the data was collected from May 2009 to December 2009. EPA issued performance standards for Phase 2 dredging based on the knowledge gained during Phase 1 and input from the peer review panel.

Goal of the Phase 1 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 Phase 1 Standard?

The performance standard for noise requires regular monitoring of the sources of noise from the cleanup. 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 sets the following limits:

How Does the Phase 1 Standard Work?

  • Regular monitoring
  • Receive, investigate and respond to complaints
  • Take action to minimize noise
  • Reporting and notification by the cleanup team to EPA
