One small area in downtown Omaha near the Asarco lead refinery did not meet the applicable National Ambient Air Quality Standard. The area was listed as non-attainment for lead. Since the facility shut down, ambient monitoring has shown a dramatic reduction in lead levels. The Department is confident that the area will soon be redesignated as attainment with the standard. As of March 1998, areas in Dakota County do not meet the state's ambient air quality standard for total reduced sulfur.
Efforts are ongoing to bring the area into compliance with the standard.
Below is an abbreviated example of an Annual Certification of Compliance . The terms and conditions to be specified in the certification are contained in your operating permit.
