Amalgam separators.
(1) All dental
					 facility waters likely to come into contact with dental amalgam waste must be
					 treated prior to discharge by an amalgam separator which is certified to ISO
					 11143 Standards (Dental equipment - amalgam separators) as incorporated by
					 reference in section
					 370.1(e) 
					 of this Title. The amalgam separator must achieve a minimum of 99 percent removal
					 efficiency of dental amalgam, by weight, in accordance with ISO 11143 test
					 procedures.
(2) Amalgam separators in
					 service at dental facilities prior to the effective date of this Subpart, must be
					 certified, but only need to achieve a minimum 95 percent removal efficiency of
					 dental amalgam, by weight, in accordance with ISO 11143 test
					 procedures.
(3) For large dental
					 facilities, the amalgam separator must meet or exceed the applicable ISO 11143
					 Standards set forth in paragraph (1) or (2) of this subdivision, but is not
					 required to be ISO certified. If such a separator is not ISO certified, then the
					 minimum removal efficiency certification must be made by a person or firm
					 licensed to practice professional engineering in the State of New York.
(4) All amalgam separators must be properly
					 sized for the volume and flow of the dental facility amalgam wastewater in
					 accordance with the manufacturer's specifications and recommendations. The
					 maximum allowable flow rate through the amalgam separator at the dental facility
					 may not exceed the maximum flow rate capacity that the separator was tested at
					 and passed in meeting the ISO standards.
(5) The amalgam separator must be installed,
					 operated, and maintained in accordance with the manufacturer's specifications and
					 recommendations. Amalgam separators must also be installed in accordance with any
					 applicable State and local building code requirements.
(6) The amalgam separator must be placed in
					 service in accordance with the requirements of this Subpart as follows:
(i) for dental facilities that begin operations
					 after the effective date of this Subpart, the amalgam separator must be placed in
					 service prior to beginning operation; or
(ii) for dental facilities operating on the
					 effective date of this Subpart, the amalgam separator must be placed in service
					 no later than two years after the effective date of this Subpart.
(7) Dental facilities where dental
					 amalgam is not placed or removed, including facilities where the specialties of
					 orthodontics, periodontics, prosthodontics and oral and maxillofacial surgery are
					 exclusively performed, are exempt from the requirements to install an amalgam
					 separator.
