Compliance Report for Dental Dischargers
On June 14, 2017, the United States Environmental Protection Agency (EPA) published Effluent Limitations Guidelines and Standards for the Dental Category (40 CFR Part 441) to reduce discharges of mercury from dental offices into publicly owned treatment works (POTWs). The regulation, which became effective on July 14, 2017, requires dental offices that place or remove amalgam to operate and maintain amalgam separator(s) and must not discharge scrap amalgam or use certain kinds of line cleaners. Existing dental offices (existing sources, whose first discharge to a POTW occurred on or before July 14, 2017) must comply by July 14, 2020. New dental offices (new sources, whose first discharge to a POTW occur after July 14, 2017) are required to comply within 90 days of the first discharge to the sewer. A copy of the regulation can be found on the Electronic Code of Federal Regulations website.
In accordance with this regulation, the Sanitation Districts have a dental office certification program. All existing and new dental offices that are connected to a sewer in the Sanitation Districts’ service area are required to complete a form called the “One-time Compliance Report for Dental Dischargers,” which can be found here.
The Sanitation Districts do not charge a fee in relation to the dental office certification program.
