If I have multiple emission units that meet one of the Rule 201 Exemption List criterion on Emissions Unit Instructions do I have report them individually?
No. In general, if you have several Rule 201 exempt emission units that must be reported in MAERS, they can be reported together as long as they have similar rated capacities and all units are subject to an identical state or federal regulation (see exception below). It is acceptable to report multiple pieces of equipment (such as space heaters) as one emission unit when the equipment is listed in the Rule 201 Exemption List on Emissions Unit Instructions and there is an aggregate throughput threshold for reporting to MAERS. Be certain to fully describe the equipment on the “Operator’s Emission Unit Description” field. Note: Emissions from other Rule 201 exempt emission units having common activities may be combined and reported at the Reporting Group level. However, sometimes it may not be a good idea to combine them together. For example, some facilities are tempted to aggregate boilers found in Rule 282(b) into one emission unit. Some of these boilers could be subject to a federal s
