EGU Workgroup Meetings

Held the 4th Thursday of the month at 2:00 p.m. Eastern. Registration URL:

April 19, 2018



1. Updated from MD and Ron Ryan (EPA) of development of 2016 crosswalk

2. Discussion of source groupings (ERTAC EGU leadership)

3. Timeline for 2016 EGU sector

4. Small EGU temporalization for 2011 platform - MD

3. Power sector modeling workshop (Serpil)


2. Discussion of source groupings (ERTAC EGU leadership)

Here are some flags for discussion that might be useful in the inventory to facilitate the use of alternative growth methodologies like ERTAC or the application of temporal profiles.

1: ERTAC EGU units-units grown and temporalized using ERTAC EGU tool. 2: Small EGUs- units that do not report to CAMD and are not grown by the ERTAC EGU tool but the application of a load following temporal profile may be appropriate. Concept based on MDE's work. 3: NonEGU CAMD units- 3A: NBTP units: these units report to CAMD for at least the ozone season but are not EGUs (> 250 mmbtu/hr fossil fuel fired units under the NBTP, for example). Modelers may want to use a temporal profile during the summer months based on reported activity or emissions in 2016. (Example - large steam providers at kraft mills, pharmaceutical companies, etc) 3B: Units converted from coal to biomass: These units report to CAMD but burn biomass, and therefore the ERTAC EGU tool does not currently have the ability to project these units. However, states may wish to use the BY temporal profile from CAMD 2016 data in the FY for modeling purposes as these units are generally load following and the data is readily available. 4: Municipal solid waste combustion-these units, when classified as "large," have CEMs but do not report to CAMD. These units burn primarily MSW. While their profiles may not be typically load following, CEM data may allow states or regions to assign specific or regional profiles appropriate for the category. They sometimes have significant emissions. 5: IPM- for those units that could be projected using IPM, in a situation where a region or state wishes to rely on those data.
