Emissions Inventory

The Division of Air Resource Management is responsible for coordinating all activities related to the compilation and periodic updating of statewide air pollutant emissions inventories.

What is an emissions inventory?

An emissions inventory is a compilation of air pollutant emissions and their sources for a given area. Categories that are usually taken into consideration include the following:

  • Point Source - Point sources are large, identifiable sources of emissions that release pollutants into the atmosphere. Examples include electric generating plants, pulp and paper mills, chemical plants, and similar "smokestack" facilities.
  • Area Source - Area sources generally have smaller emissions on an individual basis than point sources and are often too numerous to be inventoried as individual sources. Examples include dry cleaners, gas stations, and open burning activities.
  • Mobile Source - Mobile sources can be on-road or non-road. On-road sources include cars, trucks, buses, and other vehicles that travel the highway. Non-road sources include lawnmowers, locomotives, boats, and construction equipment.
What are the uses of an emissions inventory?

The emissions inventory data have various uses including:

  • Air quality assessment - National Air Quality & Emissions Trend Report, National Air Toxics Assessment (NATA), State Implementation Plan (SIP) development, regional visibility (regional haze) planning, pollutant deposition studies, and analysis of issues of heightened public concern.
  • Air permitting - Air quality modeling for permit review (National Ambient Air Quality Standards analysis, prevention of significant deterioration (PSD) increment analysis, AQ-related values analysis for Class I areas) and verification of the "baseline actual-to-projected actual" applicability test for new source review.
  • Other - Performance-based budgeting, public information and strategic planning.
How is Florida's data collected and how can I view it?

Point source data are collected via the Annual Operating Report (AOR) (DEP form number 62-210.900(5)). The majority of the facilities submit their AORs using the Electronic Annual Operating Report (EAOR) software. The AOR data can be viewed using AirInfo Search. The AOR data are reviewed and submitted to the Environmental Protection Agency (EPA) by DEP for inclusion in the National Emissions Inventory. At this time, DEP does not submit area or mobile source emissions inventory data to EPA. Instead, the state uses the EPA-derived Florida inventory for each of these categories.
