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.
