Massachusetts S3154 amends regulations on combined sewer overflows, requiring reporting, metering, and predictive modeling for water quality.

Massachusetts S3154 amends existing laws to enhance oversight and management of combined sewer overflows. The bill mandates that permittees report discharge volumes, assists in installing metering equipment, and issues public advisories. It also requires the Department of Environmental Protection to create a predictive model for water quality following overflows, using data from permittees. The bill sets standards for testing water bodies for bacteria and pollutants, and defines a 25-year, 24-hour storm event. It prohibits untreated combined sewer overflows during such events.
