Dental offices in the City of Carrollton are all required to complete the One Time Compliance Form based on the Dental Rule set forth by the Environmental Protection Agency (EPA).  

It is important for us to obtain this information from dentists as dental offices are the main source of mercury discharge into Publicly Owned Treatment Works (POTW’s). This is because many fillings are made of something called amalgam, and this amalgam contains mercury. By ensuring that dental offices are taking proper precautions and installing amalgam separators to capture the mercury, it is limiting the mercury being discharged. 

 If you are a dental office please fill out the One Time Compliance Form and either bring it into City Hall or mail it to our office at 1945 E Jackson Rd. Carrollton, TX 75006. Wet/original signatures are required on these documents. 

The One Time Compliance form is available here.
