Major Source Boiler MACT Reporting Requirements for Natural Gas Units: How to Submit Electronic Compliance Reports

Major Source Boiler MACT (40 CFR 63 Subpart DDDDD) requires the submittal of electronic compliance reports for affected boilers and process heaters, including units that are subject to work practices (tune-ups), but not emission limits under the rule.  Facilities with affected “Gas 1” units (natural gas boilers/process heaters) and other units not subject to emission limits are required to submit compliance reports for these units at the same frequency as their required tune-up.  For many “Gas 1” units, the first required compliance report under the Boiler MACT is due January 31, 2017. These reports are required to be submitted in the Compliance and Emissions Data Reporting Interface (CEDRI) located on U.S. EPA’s Central Data Exchange (CDX).
