How were the initial thresholds developed?
In developing the thresholds for what constitutes major industrial and commercial sources, EPA reviewed existing thresholds from other EPA regulations, relevant databases of waste energy projects, and existing analysis of waste energy projects by the EPA Combined Heat and Power Partnership. The proposed initial threshold for major industrial sources is 100 MMBtu/hr, which is based on the New Source Performance Standards regulation. The proposed initial threshold for major commercial sources is 1 MW average electric annual demand or 5 MMBtu/hr, which is reflective of the size of facilities associated with existing CHP in commercial applications.
