Dental Office Category Rule

What is the Dental Office Category Rule?

May contain: person, human, dentist, and clinic

The South Placer Municipal Utility District (District) is notifying dental offices within its service area of the publication of federal rules for dental offices (United States Environmental Protection Agency 40 Code of Federal Regulations Part 441 Dental Category) (Rule).  The purpose of the rule is to set a uniform, national standard that will reduce the release of mercury into the environment. 

What does the Rule require?

The Rule requires that a dental office install and maintain an amalgam separator, implement the waterline cleaner Best Management Practices (BMP) for the removal of particulate mercury and other metals from the discharge of wastewater into the sewer system, and submit a one-time report certifying compliance to the District.  The rule requires existing dental offices comply with the pretreatment standards, reporting, and recordkeeping requirements of the rule no later than July 14, 2020.  New dental offices subject to the rule must comply immediately upon discharging to the sewer system.

An exemption from the rule has been established for dental offices that do not place or remove amalgam, except under emergency situations.  Enclosed is a Frequently Asked Questions page for your reference.
