Amalgam discharge deadlines approaching

Be aware of the approaching deadlines for the amalgam separator rule, a requirement of the Clean Water Act covering dental offices that discharge wastewater into publicly owned treatment water works.

Offices open before July 14, 2017 must provide a compliance report by July 14, 2020. Newly purchased or built offices since July 14, 2017 must comply within 90 days of taking ownership. There are certain practices that are exempt as well.

The Illinois State Dental Society has more information about the rule, existing separators as well as an approved list of Illinois pretreatment wastewater plants on their website
