EPA entered into a proposed administrative settlement agreement for remedial investigation addendum/focused feasibility study under CERCLA associated with the Smeltertown site near Salida, Colorado. 

EPA proposed to revise regulations that allow for the open burning and detonation (OB/OD) of waste explosives by reducing OB/OD of waste explosives and increasing control of air emissions.
