Alaska Air Emissions Inventory & Reporting
An emission inventory is the reported actual emissions from sources within a specific time period, usually a calendar year. Inventories are developed, by sector, to provide the specific emission information used for Air Quality permitting and planning throughout the state. Emission inventory development is also required by the Environmental Protection Agency (EPA). Once developed, the various inventories are submitted to EPA. Each sector is required to be reported based on the schedule shown in the Federal Reporting Requirements Table. Major and minor point sources are categorized based on potential to emit from the previous calendar year.
