Federal regulations [40 CFR 441.50(a) (1)] requires the City to obtain a One-Time Compliance Report from new dental sources. New sources will be required to submit a one-time compliance report within 90 days, following the commencement of discharging wastewater into the POTW (public owned  treatment works). Existing Dental Dischargers or sources will have until October 2020 or 90 days after transfer of ownership to submit this report.

Dental amalgam non-users will not be required to install a separator while users will be required to do so. This will help prevent amalgam from making its way into the environment from the POTW.

If you have any questions concerning this rule, please contact Environmental Services at 972-466-3060
