A source may appoint an Alternate Designated Representative to act on behalf of the Designated Representative. Permitting The Designated Representative for each source is required to file an acid rain permit application for the source and a compliance plan to the Title V permitting authority for each affected unit at the source. The Acid Rain permits and compliance plans are simple, allow sources to fashion a compliance strategy tailored to their individual needs, and foster trading. For example, they allow sources to make real-time allowance trading decisions through the use of automatic permit amendments. Acid rain permits, which are also issued by the relevant Title V permitting authority, require that each unit account hold a sufficient number of allowances to cover the unit's SO2 emissions in each year, comply with the applicable NOx limit, and monitor and report emissions.
Permits are subject to public comment before approval.
For more information, see the acid rain permits page . Freedom to Choose The Acid Rain Program allows sources to select their own compliance strategy. For example, to reduce SO2 an affected source may repower its units, use cleaner burning fuel, or reassign some of its energy production capacity from dirtier units to cleaner ones. Sources also may decide to reduce electricity generation by adopting conservation or efficiency measures. Most options, like fuel switching, require no special prior approval, allowing the source to respond quickly to market conditions without needing government approval.
