Goal of the Standard

The goal of the 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 sets the following limits for PCBs in the air:

How the Standard Works

  • Regular monitoring
  • Taking action to minimize air quality effects
  • Reporting and notification by the cleanup team to EPA
