Mercury and TSCA: US EPA Proposes SNUR

The US EPA is proposing a significant new use rule (SNUR) under TSCA for elemental mercury used in flow meters, natural gas manometers, and pyrometers. Persons who intend to manufacture, import or process elemental mercury for use in flow meters, natural gas manometers and pyrometers would be required to notify the EPA at least 90 days before commencing the activity. The notification would enable the EPA with the opportunity to evaluate the intended use and if necessary, prohibit or limit it. The SNUR is open for comment until November 10, 2009.
