DE MINIMIS EXEMPTIONS:
Sources with potential to emit less than 5 tons per year of any criteria pollutant or 500 pounds per year of
a hazardous pollutant and less than 2,000 pounds per year of any combination of hazardous air pollutants are exempt from permitting.
MINOR SOURCE PERMITTING:
Any project that exceeds the exemption level and does not trigger Title V is subject to minor source permitting.
In the nonattainment areas of the state, offsetting and controls are likely. State BACT is required in nonattainment
areas for NOx, PM and SO2. For small engines the BACT requirement is 3 grams per horsepower hour of NOx and CO. For turbines in nonattainment areas, BACT requires attainment of 15 ppm or less for NOx and CO. For turbines in attainment areas the BACT requirement for pollutants is 25 ppm for NOX and CO.
Each individual owner can determine what type of technology he/she wants to utilize to meet BACT pollutant measures. If a unit is close to the Major Source threshold it may be required to complete some
modeling to determine the impact on the ambient air. If modeling shows the impact of the unit will be greater than
1.0 micrograms per cubic meter at a one year average or greater than 3.0 micrograms per cubic meter over a 24-hour
average for any combination of PM-10, SO2 and NOx, then LAER will be required. For CO, if modeling shows a 1-hr average higher than 2000 micrograms per cubic meter then LAER will also be required. If a unit is located in an attainment
area and it does not trigger the above ambient impacts no additional emission controls will be required. All new
sources must meet an opacity limit of 20% for all others.
MAJOR NSR/PSD PERMITTING:
250 tons per year of any criteria pollutant triggers PSD in attainment areas. Potential to emit 100 tons of CO,
PM, SO2, NOx or VOCs in nonattainment or maintenance areas triggers NSR.
TREATMENT OF EMERGENCY ENGINES:
Emergency units can only operate during emergencies. Potential to emit calculations are based on 500 hours of operation per year however, the state does not impose
an hourly limit on operation. If any facility exceeds 2 hours of operation for any reason they must notify the state but are not necessarily required to obtain a permit.
The Public Service Commission of Utah does not have any authority over the siting of electrical generation
facilities. However, local and county authorities need to be consulted in addition with the Department of
Environmental Quality.
