Figure: 30 TAC §117.3020(c)

The equation for calculating the annual average emission cap in tons per year for all electric generating facilities in the system cap.

Where:

     Capannual = the NOX annual average emission cap in tons per year;

     i = each unit in the electric power generating system;

     N = the total number of units in the emission cap;

     Hi = the average of the annual heat input for each unit in the emission cap, in million British
            thermal units per year, as certified to the executive director, for 1996, 1997, and 1998;
            and

     Ri = the emission specification of §117.3010 of this title.
