The Division of Air Resource Management’s Office of Permitting and Compliance manages DEP's Prevention of Significant Deterioration (PSD) air permitting program. When a major stationary source of emissions is constructed or modified and it is projected to emit more than a certain amount of air pollutants, the facility must perform an air quality impact analysis to ensure that the project’s future emissions will not cause or contribute to an exceedance of an established air quality standard.
The Air Modeling and Data Analysis Group reviews these analyses to determine if the applicant has provided reasonable assurances that the facility will not cause or contribute to an exceedance of an established air quality standard.
DEP has written a PSD Air Quality Modeling Best Practices document to assist applicants in preparing a PSD air quality impact analysis as part of a PSD permit application in Florida. It is recommended that applicants follow this document and consult early and often with the Air Modeling Group to ensure a smooth application process.
