Washington HFC regulations in development

The Washington State Department of Ecology continues its work on Chapter 173-443 WAC, Hydrofluorocarbons. Until the new rule is final, Washington has required manufacturers, importers and distributors to notify Ecology about their products and equipment that contain HFCs since Dec. 31, 2019. Reporting requirements are here. Ecology held an online public hearing July 21 to discuss the proposed rule language.
