Withdrawal of direct final rule.

# SUMMARY:

                        The EPA published a direct final rule titled “Quality Assurance Requirements for Continuous Opacity Monitoring Systems at Stationary Sources” in the                         **Federal Register**                         on February 14, 2012. Because we received adverse comments to the parallel proposed rule issued under the same name on February 14, 2012, we are withdrawing the direct final rule.
