Hawaii Air Permitting Issues

The state requires an air permit prior to construction, reconstructing, modifying or operating a stationary air pollution source or air pollution control equipment. There are two types of air permits: Covered Source Permits and Uncovered Source Permits. All permits are submitted to the Director of Health.

In general, covered sources include major sources of air emissions and sources subject to a federal performance or control technology standard. Noncovered sources are all other stationary sources that are not covered sources." "Noncovered source" means a stationary source constructed, modified, or relocated after March 20, 1972, that is not a covered source.

Facilities are exempt from the permitting requirements if potential annual emission are less than 500 pounds per year of any hazardous air pollutant, except lead; or two tons per year of VOCs.
