​Annual Emissions Reporting

A facility-wide annual emission report is due for each Mecklenburg County facility that has a currently active permit with Mecklenburg County Air Quality. The annual report must be submitted by April 30th of each year.

Each air quality permit contains specific conditions and limitations that detail applicable regulations for the facility’s permitted emission sources. Before you begin calculating annual air pollutant emissions for each of your emission sources, you will want to gather data on processes and equipment that will help in determining the pollutants emitted during the previous year.
