AIR EMISSIONS REGULATIONS:

Air Quality Status The county is in serious nonattainment for PM10 and serious nonattainment for CO.
EPA's Nonattainment Areas
Major Source Threshold 70 tons of PM10 or 100 tons of CO triggers NSR. 250 tons of any other criteria pollutant triggers PSD
Minor Source Permitting Exemption None
Minor Source Treatment BACT
Emergency Generating Limits Hourly limit and BACT

DE MINIMIS EXEMPTIONS:

The county does not exempt any units.

MINOR SOURCE PERMITTING:

All units must obtain a permit. BACT is required for all criteria pollutants. The county does not have a BACT cost threshold established, rather permitting officials will look for a "breaking point" in the cost of controls. This is a point where the cost of an additional control becomes significantly more expensive then each addition before it, this is the "breaking point." Sources with potential emissions above the following must complete LAER:

PM10: 5 tons per year or 20 pounds per day
CO: 25 tons per year or 150 pounds per day or 15 pounds per hour
VOCs: 40 tons per year or 300 pounds per day or 30 pounds per hour

The length of the permitting process can vary widely, there is a no official time restriction.

MAJOR NSR/PSD PERMITTING:

70 tons of PM-10 or 100 tons of CO triggers NSR. 250 tons of any other criteria pollutant triggers PSD. However, BACT and LAER are triggered at lower levels (see above).

TREATMENT OF EMERGENCY ENGINES:

Emergency generators will typically be permitted at 52 hours per year or less and must complete a BACT analysis.

BUILDING, ZONING AND FIRE CODES:

All stationary sources in Clark County must complete a Fire Department Survey Form.
