Current through Reg. 50, No. 13; March 28, 2025
You must keep records of eight items.
(1) Records of monitoring data. Document six
parameters measured using continuous monitoring systems:
(A) All 6-minute average levels of
opacity.
(B) All 1-hour average
concentrations of sulfur dioxide emissions.
(C) For Class I municipal waste combustion
units only, all 1-hour average concentrations of nitrogen oxides
emissions.
(D) All 1-hour average
concentrations of carbon monoxide emissions.
(E) All 1-hour average load levels of your
municipal waste combustion unit.
(F) All 1-hour average flue gas temperatures
at the inlet of the particulate matter control device.
(2) Records of average concentrations and
percent reductions. Document five parameters:
(A) All 24-hour daily block geometric average
concentrations of sulfur dioxide emissions or average percent reductions of
sulfur dioxide emissions.
(B) For
Class I municipal waste combustion units only, all 24-hour daily arithmetic
average concentrations of nitrogen oxides emissions.
(C) All 4-hour block or 24-hour daily block
arithmetic average concentrations of carbon monoxide emissions.
(D) All 4-hour block arithmetic average load
levels of your municipal waste combustion unit.
(E) All 4-hour block arithmetic average flue
gas temperatures at the inlet of the particulate matter control
device.
(3) Records of
exceedances. Document three items:
(A)
Calendar dates whenever any of the five pollutant or parameter levels recorded
in paragraph (2) of this section or the opacity level recorded in paragraph
(1)(A) of this section did not meet the emission limits or operating levels
specified in this division.
(B)
Reasons you exceeded the applicable emission limits or operating
levels.
(C) Corrective actions you
took, or are taking, to meet the emission limits or operating levels.
(4) Records of minimum data.
Document three items:
(A) Calendar dates for
which you did not collect the minimum amount of data required under §
113.2134 and §
113.2149 of this title (relating
to What is the minimum amount of monitoring data I must collect with my
continuous emission monitoring systems and is the data collection requirement
enforceable? and What is the minimum amount of data I must collect with my
continuous parameter monitoring systems and is the data collection requirement
enforceable?). Record those dates for five types of pollutants and parameters:
(i) Sulfur dioxide emissions.
(ii) For Class I municipal waste combustion
units only, nitrogen oxides emissions.
(iii) Carbon monoxide emissions.
(iv) Load levels of your municipal waste
combustion unit.
(v) Temperatures
of the flue gases at the inlet of the particulate matter control
device.
(B) Reasons you
did not collect the minimum data.
(C) Corrective actions you took or are taking
to obtain the required amount of data.
(5) Records of exclusions. Document each time
you have excluded data from your calculation of averages for any of the
following five pollutants or parameters and the reasons the data were excluded:
(A) Sulfur dioxide emissions.
(B) For Class I municipal waste combustion
units only, nitrogen oxides emissions.
(C) Carbon monoxide emissions.
(D) Load levels of your municipal waste
combustion unit.
(E) Temperatures
of the flue gases at the inlet of the particulate matter control
device.
(6) Records of
drift and accuracy. Document the results of your daily drift tests and
quarterly accuracy determinations according to Procedure 1 of 40 Code of
Federal Regulations Part 60, Appendix F. Keep those records for the sulfur
dioxide, nitrogen oxides (Class I municipal waste combustion units only), and
carbon monoxide continuous emissions monitoring systems.
(7) Records of the relationship between
oxygen and carbon dioxide. If you choose to monitor carbon dioxide instead of
oxygen as a diluent gas, document the relationship between oxygen and carbon
dioxide, as specified in §
113.2133 of this title (relating
to What must I do if I choose to monitor carbon dioxide instead of oxygen as a
diluent gas?).
(8) Records of
calendar dates. Include the calendar date on each record.
