TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 60_STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES--Table of
Contents
Subpart A_General Provisions
Sec. 60.13 Monitoring requirements.
(a) For the purposes of this section, all continuous monitoring
systems required under applicable subparts shall be subject to the
provisions of this section upon promulgation of performance
specifications for continuous monitoring systems under appendix B to
this part and, if the continuous monitoring system is used to
demonstrate compliance with emission limits on a continuous basis,
appendix F to this part, unless otherwise specified in an applicable
subpart or by the Administrator. Appendix F is applicable December 4,
1987.
(b) All continuous monitoring systems and monitoring devices shall
be installed and operational prior to conducting performance tests under
Sec. 60.8. Verification of operational status
[[Page 71]]
shall, as a minimum, include completion of the manufacturer's written
requirements or recommendations for installation, operation, and
calibration of the device.
(c) If the owner or operator of an affected facility elects to
submit continous opacity monitoring system (COMS) data for compliance
with the opacity standard as provided under Sec. 60.11(e)(5), he shall
conduct a performance evaluation of the COMS as specified in Performance
Specification 1, appendix B, of this part before the performance test
required under Sec. 60.8 is conducted. Otherwise, the owner or operator
of an affected facility shall conduct a performance evaluation of the
COMS or continuous emission monitoring system (CEMS) during any
performance test required under Sec. 60.8 or within 30 days thereafter
in accordance with the applicable performance specification in appendix
B of this part, The owner or operator of an affected facility shall
conduct COMS or CEMS performance evaluations at such other times as may
be required by the Administrator under section 114 of the Act.
(1) The owner or operator of an affected facility using a COMS to
determine opacity compliance during any performance test required under
Sec. 60.8 and as described in Sec. 60.11(e)(5) shall furnish the
Administrator two or, upon request, more copies of a written report of
the results of the COMS performance evaluation described in paragraph
(c) of this section at least 10 days before the performance test
required under Sec. 60.8 is conducted.
(2) Except as provided in paragraph (c)(1) of this section, the
owner or operator of an affected facility shall furnish the
Administrator within 60 days of completion two or, upon request, more
copies of a written report of the results of the performance evaluation.
(d)(1) Owners and operators of a CEMS installed in accordance with
the provisions of this part, must check the zero (or low level value
between 0 and 20 percent of span value) and span (50 to 100 percent of
span value) calibration drifts at least once daily in accordance with a
written procedure. The zero and span must, as a minimum, be adjusted
whenever either the 24-hour zero drift or the 24-hour span drift exceeds
two times the limit of the applicable performance specification in
appendix B of this part. The system must allow the amount of the excess
zero and span drift to be recorded and quantified whenever specified.
Owners and operators of a COMS installed in accordance with the
provisions of this part, must automatically, intrinsic to the opacity
monitor, check the zero and upscale (span) calibration drifts at least
once daily. For a particular COMS, the acceptable range of zero and
upscale calibration materials is as defined in the applicable version of
PS-1 in appendix B of this part. For a COMS, the optical surfaces,
exposed to the effluent gases, must be cleaned before performing the
zero and upscale drift adjustments, except for systems using automatic
zero adjustments. The optical surfaces must be cleaned when the
cumulative automatic zero compensation exceeds 4 percent opacity.
(2) Unless otherwise approved by the Administrator, the following
procedures must be followed for a COMS. Minimum procedures must include
an automated method for producing a simulated zero opacity condition and
an upscale opacity condition using a certified neutral density filter or
other related technique to produce a known obstruction of the light
beam. Such procedures must provide a system check of all active analyzer
internal optics with power or curvature, all active electronic circuitry
including the light source and photodetector assembly, and electronic or
electro-mechanical systems and hardware and or software used during
normal measurement operation.
(e) Except for system breakdowns, repairs, calibration checks, and
zero and span adjustments required under paragraph (d) of this section,
all continuous monitoring systems shall be in continuous operation and
shall meet minimum frequency of operation requirements as follows:
(1) All continuous monitoring systems referenced by paragraph (c) of
this section for measuring opacity of emissions shall complete a minimum
of one cycle of sampling and analyzing for each successive 10-second
period and
[[Page 72]]
one cycle of data recording for each successive 6-minute period.
(2) All continuous monitoring systems referenced by paragraph (c) of
this section for measuring emissions, except opacity, shall complete a
minimum of one cycle of operation (sampling, analyzing, and data
recording) for each successive 15-minute period.
(f) All continuous monitoring systems or monitoring devices shall be
installed such that representative measurements of emissions or process
parameters from the affected facility are obtained. Additional
procedures for location of continuous monitoring systems contained in
the applicable Performance Specifications of appendix B of this part
shall be used.
(g) When the effluents from a single affected facility or two or
more affected facilities subject to the same emission standards are
combined before being released to the atmosphere, the owner or operator
may install applicable continuous monitoring systems on each effluent or
on the combined effluent. When the affected facilities are not subject
to the same emission standards, separate continuous monitoring systems
shall be installed on each effluent. When the effluent from one affected
facility is released to the atmosphere through more than one point, the
owner or operator shall install an applicable continuous monitoring
system on each separate effluent unless the installation of fewer
systems is approved by the Administrator. When more than one continuous
monitoring system is used to measure the emissions from one affected
facility (e.g., multiple breechings, multiple outlets), the owner or
operator shall report the results as required from each continuous
monitoring system.
(h) Owners or operators of all continuous monitoring systems for
measurement of opacity shall reduce all data to 6-minute averages and
for continuous monitoring systems other than opacity to 1-hour averages
for time periods as defined in Sec. 60.2. Six-minute opacity averages
shall be calculated from 36 or more data points equally spaced over each
6-minute period. For continuous monitoring systems other than opacity,
1-hour averages shall be computed from four or more data points equally
spaced over each 1-hour period. Data recorded during periods of
continuous system breakdown, repair, calibration checks, and zero and
span adjustments shall not be included in the data averages computed
under this paragraph. For owners and operators complying with the
requirements in Sec. 60.7(f) (1) or (2), data averages must include any
data recorded during periods of monitor breakdown or malfunction. An
arithmetic or integrated average of all data may be used. The data may
be recorded in reduced or nonreduced form (e.g., ppm pollutant and
percent O2 or ng/J of pollutant). All excess emissions shall
be converted into units of the standard using the applicable conversion
procedures specified in subparts. After conversion into units of the
standard, the data may be rounded to the same number of significant
digits as used in the applicable subparts to specify the emission limit
(e.g., rounded to the nearest 1 percent opacity).
(i) After receipt and consideration of written application, the
Administrator may approve alternatives to any monitoring procedures or
requirements of this part including, but not limited to the following:
(1) Alternative monitoring requirements when installation of a
continuous monitoring system or monitoring device specified by this part
would not provide accurate measurements due to liquid water or other
interferences caused by substances in the effluent gases.
(2) Alternative monitoring requirements when the affected facility
is infrequently operated.
(3) Alternative monitoring requirements to accommodate continuous
monitoring systems that require additional measurements to correct for
stack moisture conditions.
(4) Alternative locations for installing continuous monitoring
systems or monitoring devices when the owner or operator can demonstrate
that installation at alternate locations will enable accurate and
representative measurements.
(5) Alternative methods of converting pollutant concentration
measurements to units of the standards.
(6) Alternative procedures for performing daily checks of zero and
span
[[Page 73]]
drift that do not involve use of span gases or test cells.
(7) Alternatives to the A.S.T.M. test methods or sampling procedures
specified by any subpart.
(8) Alternative continuous monitoring systems that do not meet the
design or performance requirements in Performance Specification 1,
appendix B, but adequately demonstrate a definite and consistent
relationship between its measurements and the measurements of opacity by
a system complying with the requirements in Performance Specification 1.
The Administrator may require that such demonstration be performed for
each affected facility.
(9) Alternative monitoring requirements when the effluent from a
single affected facility or the combined effluent from two or more
affected facilities is released to the atmosphere through more than one
point.
(j) An alternative to the relative accuracy (RA) test specified in
Performance Specification 2 of appendix B may be requested as follows:
(1) An alternative to the reference method tests for determining RA
is available for sources with emission rates demonstrated to be less
than 50 percent of the applicable standard. A source owner or operator
may petition the Administrator to waive the RA test in Section 8.4 of
Performance Specification 2 and substitute the procedures in Section
16.0 if the results of a performance test conducted according to the
requirements in Sec. 60.8 of this subpart or other tests performed
following the criteria in Sec. 60.8 demonstrate that the emission rate
of the pollutant of interest in the units of the applicable standard is
less than 50 percent of the applicable standard. For sources subject to
standards expressed as control efficiency levels, a source owner or
operator may petition the Administrator to waive the RA test and
substitute the procedures in Section 16.0 of Performance Specification 2
if the control device exhaust emission rate is less than 50 percent of
the level needed to meet the control efficiency requirement. The
alternative procedures do not apply if the continuous emission
monitoring system is used to determine compliance continuously with the
applicable standard. The petition to waive the RA test shall include a
detailed description of the procedures to be applied. Included shall be
location and procedure for conducting the alternative, the concentration
or response levels of the alternative RA materials, and the other
equipment checks included in the alternative procedure. The
Administrator will review the petition for completeness and
applicability. The determination to grant a waiver will depend on the
intended use of the CEMS data (e.g., data collection purposes other than
NSPS) and may require specifications more stringent than in Performance
Specification 2 (e.g., the applicable emission limit is more stringent
than NSPS).
(2) The waiver of a CEMS RA test will be reviewed and may be
rescinded at such time, following successful completion of the
alternative RA procedure, that the CEMS data indicate that the source
emissions are approaching the level. The criterion for reviewing the
waiver is the collection of CEMS data showing that emissions have
exceeded 70 percent of the applicable standard for seven, consecutive,
averaging periods as specified by the applicable regulation(s). For
sources subject to standards expressed as control efficiency levels, the
criterion for reviewing the waiver is the collection of CEMS data
showing that exhaust emissions have exceeded 70 percent of the level
needed to meet the control efficiency requirement for seven,
consecutive, averaging periods as specified by the applicable
regulation(s) [e.g., Sec. 60.45(g) (2) and (3), Sec. 60.73(e), and
Sec. 60.84(e)]. It is the responsibility of the source operator to
maintain records and determine the level of emissions relative to the
criterion on the waiver of RA testing. If this criterion is exceeded,
the owner or operator must notify the Administrator within 10 days of
such occurrence and include a description of the nature and cause of the
increasing emissions. The Administrator will review the notification and
may rescind the waiver and require the owner or operator to conduct a RA
test

Editorial Note: At 65 FR 61749, Oct. 17, 2000, Sec. 60.13 was
amended by revising the words ``ng/J of pollutant'' to read ``ng of
pollutant per J of heat input'' in the sixth sentence of paragraph (h).
However, the amendment could not be incorporated because the words ``ng/
J of pollutant'' do not exist in the sixth sentence of paragraph (h).
