Acid Rain Program: Continuous Emission Monitoring

On May 17, 1995, EPA published direct final amendments to the Continuous Emission Monitoring (CEM) rule in the Acid Rain Program for the purpose of making implementation of the program simpler, streamlined, and more efficient. The amendments to the original January 11, 1993 rule became final and effective on July 17, 1995. During the public comment period on the direct final rule and its companion proposed rule, EPA received significant, adverse comments on those amended provisions that related to notifications for periodic relative accuracy test audits. EPA is removing the provisions added in the direct final rule related to notifications. EPA will address the removed provisions in a future final rule. EPA is also extending the public comment period on the removed provisions for 15 days to allow the public to respond to the significant, adverse comments. All other provisions of the direct final rule remain final. In addition, EPA is publishing technical corrections of typographical and similar inadvertent errors in the final rule, as promulgated May 17, 1995.
