Congress established the program in title IV of the 1990 Clean Air Act (CAA) Amendments to address acid deposition by reducing emissions of sulfur dioxide (SO2) and nitrogen oxides (NOX). This renewal generally outlines programmatic aspects as established in the previous ICR with adjustments to reflect current labor costs and estimates of the numbers of respondents and transactions. To reduce SO2 emissions, the Acid Rain Program uses a cap-and-trade system applicable to most large fossil fuel-fired electricity generating units in the contiguous United States. Affected sources are required to hold one tradable allowance for each ton of SO2 emitted, and the total number of allowances issued is capped. In addition to affected sources, any person or entity may establish an account to buy and sell allowances. EPA is required to conduct an allowance auction each year to promote market liquidity and price transparency. To reduce NOX emissions, the Acid Rain Program applies NOX emission rate limits to a subset of affected units. Each such unit may either meet its standard emission rate limit, arrange to comply on a group basis under an averaging plan, or seek approval for an alternative emission limitation (AEL) based on demonstrated inability to meet its otherwise applicable standard limit. Affected units under the Acid Rain Program are required to monitor opacity and SO2, NOX, and carbon dioxide (CO2) emissions using continuous emission monitoring systems (CEMS) or alternative monitoring methods approved by the EPA Administrator. All affected units are also required to obtain and periodically renew permits that identify their plans for complying with the programs applicable SO2 and NOX requirements. As in previous Acid Rain Program ICRs, most of the topical discussions in this ICR renewal are organized around the main program elements established under different CAA sections: Allowance transfers (CAA section 403); Permits (CAA section 408); Emissions monitoring (CAA section 412); Auctions (CAA section 416); NOx permitting (CAA section 407).

Overall, the estimated annual respondent burden hours decreased by approximately 3.6% from the previous ICR and the estimate respondent capital/O&M costs decreased by approximately 4.8%. These decreases are largely attributed to the reduction in the number of Acid Rain affected units due to unit retirements. It is also due to a shift towards less burdensome monitoring methodologies. As units shift to burning natural gas this provides opportunities to use alternative monitoring methods which require less costly equipment and require less labor hours. Additionally, with the abundance of available Acid Rain allowances there are less allowance transactions occurring and less participation in the Acid Rain auction.
