In November 2001, the University of Arizona (U of A) was issued Title V Air Quality Permit #2371 by the Pima County Department of Environmental Compliance (PDEQ). This permit governs the U of A's operation of equipment and activities that generate regulated air emissions. The majority of the permit addresses equipment and operations under the control of Facilities Management. Other sections of the permit address equipment under the control of, and activities coordinated by, the Student Unions, University Animal Care and Residence Life.
The University is expected to keep current the Potential-to-Emit declarations expressed in tons per year. The following pollutants are included: nitrogen oxides, carbon monoxide, particulate matter, sulfur dioxide, volatile organic compounds and other hazardous air pollutants. The U of A was considered a "Major Source" for nitrogen oxides and carbon monoxide and a minor source for all other criteria and hazardous pollutants in 2001. The major source threshold is 100 tons per year calculated as Potential-to-Emit, not actual emissions. Subsequent permit revisions have downgraded U of A carbon monoxide emissions from major to minor source.
The U of A must re-apply to PDEQ prior to permit expiration every five years. Regulated equipment and activities included but are not limited to: natural gas fired turbines, emergency generators, boilers, gasoline fired equipment, fuel storage tanks, incinerators, surface coating operations, cooling towers, storage piles, demolition/renovation, and non-vehicle air conditioner maintenance. Visible emissions from all activities are also regulated. In addition, the evaporation of waste solvent in a laboratory is not allowed under best management practices.
If you have institutional knowledge of pollutant emitting equipment or activities on campus that may need to be included or removed from the permit, please call the Department of Risk Management & Safety at 621-1790 and share the information.
