Mercury Information

State and EPA Guidelines for Control of Mercury Wastes

Golden’s wastewater program currently implements a voluntary mercury waste control program emphasizing responsible good housekeeping practices for those businesses that use mercury containing products. The Environmental Protection Agency offers guidance that requires local pretreatment programs to require and enforce “Best Management Practices” as a means to control mercury wastes in the sanitary sewer system. Specifically, these “BMPs” are a requirement of local dentist and orthodontic offices in Golden. The American Dental Association signed a Memorandum of Understanding to promote the voluntary installation and use of mercury amalgam separators in member establishments.
