Primary Copper Smelting Area Sources: National Emissions Standards for Hazardous Air Pollutants (NESHAP)
On this page:
On January 23, 2007, the U.S. Environmental Protection Agency (EPA) promulgated final air toxics standards for the Primary Copper Smelting Area Source category. Primary copper smelting is the industry which refines copper sulfide ore concentrate from mined ore to produce anode grade copper, using pyrometallurgical processes. Pyrometallurgical processes use high temperature furnaces to smelt or refine ores to produce pure metals or metal oxides. This final rule requires existing primary copper smelters that are area sources to control air toxic emissions by assuring they limit particulate matter emissions.

01/23/2007 - Final rule.
