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?

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 Standard Work?

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