Maryland Air Permitting Issues
Written October 17, 2019
In Maryland, all facilities with more than one ton per year of uncontrolled emissions are required to obtain a permit to construct if adding or modifying equipment. The state may or may not require the facility to obtain an operating permit.
If a facility's emissions of VOCs, before controls, are less than 1 ton per year, then there is no requirement for registration or permitting. The state does have an approved Title V permit program in place. Sources with the potential to emit 50 tons per year must comply with the new Title V permit requirements. Facilities located in Calvert, Charles, Frederick, Montgomery, or Prince Georges, counties with total actual VOC emissions of 25 tons per year must obtain a Title V permit. The Department has a policy for synthetic minor permits that impacts facilities with actual emissions of each regulated air pollutant less than 50% of the applicability threshold. All facilities with emissions of 25 tons of VOCs per year must file an annual emission statement by April 1 of each year.
