EPA has released Update #12 to the Acid Rain Program Policy Manual which includes over eighty new policy questions. Update #12 introduces two new sections to the Manual: (1) Section 22: Subtractive Stack Configurations and (2) Section 24: Common Stack NOx Emission Rate Monitoring and Apportionment. Update #12 also formally incorporates many of the previously issued questions and answers from the October 1999 Implementation Conference and the November 1999 ESC Users Group Meeting. The contact list provided in Appendix A, as well as the "Quarterly Report Review Process for Determining Final Annual Data" in Appendix C has also been revised. A copy of Update #12 is located in our FTP Library.
