Air Emissions Reporting Requirements (AERR)

The United States Environmental Protection Agency (EPA) has long required states to submit emission inventories containing information regarding the emissions of criteria pollutants and their precursors. In a Federal Register notice dated December 17, 2008 [73 FR 76540] EPA promulgated a final rule referred to as the Air Emissions Reporting Requirements (AERR).

The purpose of the AERR is to harmonize reporting requirements under the NOx SIP Call and the Clean Air Interstate Rule (CAIR) which requires inventories to be submitted 12 months after the beginning of each calendar year, and Consolidated Emissions Reporting Rule (CERR) which requires inventories to be submitted 17 months after the beginning of each calendar year. It also removes and simplifies some existing emissions reporting requirements which the EPA believes are not necessary or appropriate; allows states to better track changes in source emissions, shutdowns, and startups over time by using the 40 CFR 70 definition of major source for point source reporting (which defines sources based on potential to emit); deletes a requirement for states to report biogenic emissions; and offers states the option of reporting emissions for certain source categories.

Also involved in this action, the Department of Health and Environmental Control (DHEC) proposes to amend Regulation 61-62.1, Definitions and General Requirements, which currently specifies that major hazardous air pollutants (HAP) sources need only submit a summary sheet and calculations showing the source wide emissions of all HAPs emitted in excess of 200 pounds/year. DHEC proposes to delete this specification so that more detailed HAP data can be collected to insure that the National Emissions Inventory (NEI) maintained by EPA contains the best available data. DHEC is also specifying reporting from sources with greater than 10 tons per year (tpy) for a single HAP and 25 tpy for combined total HAP emissions. While DHEC originally proposed to consider changing the date that facilities need to submit annual emission data, the final revision will not change and the date within the regulation will remain at March 31st.
