Rhode Island General Laws Title 23. Health and Safety § 23-24.9-9.3. Amalgam separators

No later than July 1, 2008, a dental office that, in the course of treating its patients, places or removes dental amalgam must install an amalgam separator system in the wastewater discharge line.  For the purposes of this section, “an amalgam separator system” means a device that removes dental amalgam from the waste stream prior to discharge into either the local public wastewater system or a private septic system located at the dental facility and that has been certified as conforming to the standards of ISO 11143, Dental Equipment--Amalgam Separators.  A dental office must demonstrate proper installation, operation, maintenance, and amalgam waste recycling or disposal in accordance with the manufacturer's recommendations by maintaining and submitting as necessary annual records on waste shipment and maintenance of the system and any other reporting required in this section.  Records of the previous three (3) years shall be maintained at all times.  Methods or technologies other than amalgam separators that achieve equivalent or greater dental amalgam discharge reductions and that are approved by the agency shall be deemed to comply with the requirements of this subsection.
