Q26. Is there a simple way for facilities with stationary fuel combustion units to determine if they will be required to report?

A26. Yes.  In order to reduce burden on small emitters, EPA is not including any facility that has an aggregate maximum rated heat input capacity of the stationary fuel combustion units of less than 30 mmBtu/hr and no other emission sources within their boundary. Stationary combustion units include among others boilers, combustion turbines, engines, incinerators, and process heaters. According to our analysis, a facility with stationary combustion units that has a maximum rated heat input capacity of less than 30 mmBtu/hr will not exceed the threshold of 25,000 metric tons of carbon dioxide equivalent (mtCO₂e) per year.  In the event that the aggregate maximum rated heat input capacity of the stationary combustion units at the facility exceed 30 mmBtu/hr, then the facility will need to do further calculations to determine if it meets the threshold for reporting.  EPA has developed an on-line applicability tool to help facilities assess if they are required to report.  This tool is available on the Greenhouse Gas (GHG) Reporting Rule website.
