While amalgam separators are already required in all dental offices in WA that use mercury-containing amalgams, dental offices must submit a new one-time compliance report by Oct. 12, 2020.
Under a
federal rule adopted by the Environmental Protection Agency in 2017, many dental practices will need an installed amalgam separator by July 14, 2020. The new standards under the Clean Water Act are consistent with the state level Amalgam Rule and aim to prevent the mercury contained in dental amalgam from entering the air, water, and land.
While amalgam separators are already required in all dental offices in Washington state that use mercury-containing amalgams, to comply with the rule, dental offices must submit a new one-time compliance report by October 12, 2020. The report and details on how to submit the report can be found through the
Department of Ecology.
Dental offices starting business after July 14, 2017, must complete and submit the report within 90 days of accepting patients.
All dental offices that use mercury amalgam separators and discharge wastewater to a publicly owned sewer must fill out the compliance report. However, offices that do not place dental amalgam, and do not remove dental amalgam except in limited emergency or unplanned, unanticipated circumstances are exempt from further requirements as long as they submit a one-time compliance report attesting their exempt status. The following dental specialties are exempt from the rule: oral pathology, oral and maxillofacial radiology, oral and maxillofacial surgery, orthodontics, periodontics, and prosthodontics.
