On August 21, 2012 the U.S. Court of Appeals for the D.C. Circuit issued its ruling on CSAPR.
On December 30, 2011, the U.S. Court of Appeals for the District of Columbia Circuit stayed the Cross-State Air Pollution Rule. Consistent with this decision, EPA will not be taking action to implement the rule pending further order of the court. If market participants wish to use the CAMD Business System to record transfers of the CSAPR allowances or to record other CSAPR related information, they may do so although they are not required to at this time. EPA will not take any further action to implement the rule, such as allocating allowances or conducting annual reconciliation, while the stay is in effect.AAEA is registered in EPA's Acid Rain credits trading program.
