\a\ If you are conducting stack tests to demonstrate compliance and your performance tests for this pollutant
  for at least 2 consecutive years show that your emissions are at or below this limit, you can skip testing
  according to Sec.   63.7515 if all of the other provisions of Sec.   63.7515 are met. For all other pollutants
  that do not contain a footnote ``a'', your performance tests for this pollutant for at least 2 consecutive
  years must show that your emissions are at or below 75 percent of this limit in order to qualify for skip
  testing.
\b\ Incorporated by reference, see Sec.   63.14.
\c\ If your affected source is a new or reconstructed affected source that commenced construction or
  reconstruction after June 4, 2010, and before April 1, 2013, you may comply with the emission limits in Table
  11, 12, or 13 to this subpart until January 31, 2016. On and after January 31, 2016, but before October 6,
  2025 you may comply with the emission limits in Table 14 to this subpart. On and after October 6, 2025 you
  must comply with the emission limits in this Table 1.
\d\ An owner or operator may determine compliance with the carbon monoxide emissions limit using CO2 as a
  diluent correction in place of oxygen as described in Sec.   63.7525(a)(1). EPA Method 19 F-factors in 40 CFR
  part 60, appendix A-7, and EPA Method 19 equations in 40 CFR part 60, appendix A-7, must be used to generate
  the appropriate CO2 correction percentage for the fuel type burned in the unit and must also take into account
  that the 3-percent oxygen correction is to be done on a dry basis. The methodology must account for any CO2
  being added to, or removed from, the emissions gas stream as a result of limestone injection, scrubber media,
  etc. This methodology must be detailed in the site-specific monitoring plan developed according to Sec.
  63.7505(d).

\a\ If you are conducting stack tests to demonstrate compliance and your performance tests for this pollutant
  for at least 2 consecutive years show that your emissions are at or below this limit, you can skip testing
  according to Sec.   63.7515 if all of the other provisions of Sec.   63.7515 are met. For all other pollutants
  that do not contain a footnote a, your performance tests for this pollutant for at least 2 consecutive years
  must show that your emissions are at or below 75 percent of this limit in order to qualify for skip testing.

\c\ An owner or operator may determine compliance with the carbon monoxide emissions limit be determined using
  CO2 as a diluent correction in place of oxygen as described in Sec.   63.7525(a)(1). EPA Method 19 F-factors
  in 40 CFR part 60, appendix A-7, and EPA Method 19 equations in 40 CFR part 60, appendix A-7, must be used to
  generate the appropriate CO2 correction percentage for the fuel type burned in the unit and must also take
  into account that the 3-percent oxygen correction is to be done on a dry basis. The methodology must account
  for any CO2 being added to, or removed from, the emissions gas stream as a result of limestone injection,
  scrubber media, etc. This methodology must be detailed in the site-specific monitoring plan developed
  according to Sec.   63.7505(d).
\d\ Before October 6, 2025 you may comply with the emission limits in Table 15 to this subpart. On and after
  October 6, 2025], you must comply with the emission limits in this Table 2.

  oxygen level, if you conduct multiple performance tests, you must set the minimum oxygen level at the lower of
  the minimum values established during the performance tests. For maximum operating load, if you conduct
  multiple performance tests, you must set the maximum operating load at the lower of the maximum values

\a\ If you are conducting stack tests to demonstrate compliance and your performance tests for this pollutant
  for at least 2 consecutive years show that your emissions are at or below this limit, you can skip testing
  according to Sec.   63.7515 if all of the other provision of Sec.   63.7515 are met. For all other pollutants
  that do not contain a footnote ``a'', your performance tests for this pollutant for at least 2 consecutive
  years must show that your emissions are at or below 75 percent of this limit in order to qualify for skip
  testing.
\b\ Incorporated by reference, see Sec.   63.14.
\c\ An owner or operator may determine compliance with the carbon monoxide emissions limit using carbon dioxide
  as a diluent correction in place of oxygen as described in Sec.   63.7525(a)(1). EPA Method 19 F-factors in 40
  CFR part 60, appendix A-7, and EPA Method 19 equations in 40 CFR part 60, appendix A-7, must be used to
  generate the appropriate CO2 correction percentage for the fuel type burned in the unit, and must also take
  into account that the 3% oxygen correction is to be done on a dry basis. The methodology must account for any
  CO2 being added to, or removed from, the emissions gas stream as a result of limestone injection, scrubber
  media, etc. This methodology must be detailed in the site-specific monitoring plan developed according to Sec.
    63.7505(d).

\a\ If you are conducting stack tests to demonstrate compliance and your performance tests for this pollutant
  for at least 2 consecutive years show that your emissions are at or below this limit, you can skip testing
  according to Sec.   63.7515 if all of the other provision of Sec.   63.7515 are met. For all other pollutants
  that do not contain a footnote ``a'', your performance tests for this pollutant for at least 2 consecutive
  years must show that your emissions are at or below 75 percent of this limit in order to qualify for skip
  testing.
\b\ Incorporated by reference, see Sec.   63.14.

\c\ An owner or operator may determine compliance with the carbon monoxide emissions limit using carbon dioxide
  as a diluent correction in place of oxygen as described in Sec.   63.7525(a)(1). EPA Method 19 F-factors in 40
  CFR part 60, appendix A-7, and EPA Method 19 equations in 40 CFR part 60, appendix A-7, must be used to
  generate the appropriate CO2 correction percentage for the fuel type burned in the unit, and must also take
  into account that the 3% oxygen correction is to be done on a dry basis. The methodology must account for any
  CO2 being added to, or removed from, the emissions gas stream as a result of limestone injection, scrubber
  media, etc. This methodology must be detailed in the site-specific monitoring plan developed according to Sec.
    63.7505(d).
