Figure: 30 TAC §117.320(c)(1)

Where:

     Cap_30day = the NO_X 30-day rolling average emission cap in pounds per day;

     i = each EGF in the electric power generating system;

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

     H_i =  (A)  the average of the daily heat input for each EGF in the emission cap, in million
                         British thermal units per day (MMBtu per day), as certified to the
                         executive director, for the system highest 30-day period in the nine months
                         of July, August, and September 1997, 1998, and 1999;

               (B) for an EGF exempt from the 40 Code of Federal Regulations (CFR) Part 75
                      monitoring requirements, if the heat input data corresponding to the system highest
                      30-day period (as determined for an EGF in the system subject to 40 CFR Part 75
                      monitoring) is not available, the daily average of the highest calendar month heat
                      input in 1997 - 1999 may be used;

               (C) the level of activity authorized by the executive director for the third quarter (July,
                      August, and September), until such time two consecutive third quarters of actual
                      level of activity data are available after the end of the adjustment period as defined
                      in §101.350 of this title (relating to Definitions), must be used for the following:

                      (i)  an EGF that the owner or operator has submitted, under Chapter 116 of this title
                           (relating to Control of Air Pollution by Permits for New Construction or
                           Modification), an application determined to be administratively complete by
                           the executive director before January 2, 2001;

                      (ii)  an EGF that qualifies for a permit by rule under Chapter 106 of this title
                           (relating to Permits by Rule) and have commenced construction before
                           January 2, 2001; and

                      (iii)  an EGF that was not in operation before January 1, 1997;

               (D) after two consecutive third quarters of actual level of activity data are available for
                      an EGF described in subsection (c)(1) of this section, variable (C) of this figure, the
                      owner or operator may calculate the baseline as the average of any two consecutive
                      third quarters in the first five years of operation. The five-year period begins at the
                      end of the adjustment period as defined in §101.350 of this title; and

               (E) in extenuating circumstances, the owner or operator of an EGF may request, subject
                      to approval of the executive director, up to two additional calendar years to
                      establish the baseline period described in subsection (c)(1) of this section, variable
                      (A) - (D) of this figure. Applications seeking an alternate baseline period must be
                      submitted by the owner or operator of the EGF to the executive director:

                      (i)  no later than December 31, 2001; or

                      (ii)  for an EGF that the baseline period as described in subsection (c)(1) of this
                           section, variable (A) - (D) of this figure is not complete by December 31, 2001,
                           no later than 90 days after completion of the baseline period; and

     R_i = the emission specification of §117.310(a) of this title.
