In Title 40 of the Code of Federal Regulations, parts 50 to 51,
revised as of July 1, 1998, the text appearing on page 345 duplicates
the text on page 344 and should be removed. As corrected the text on
page 345 should read as follows:

high level of precision and accuracy for the purposes of this test.
This method is not meant to replace the calibration requirements of
test methods. In addition to the requirements in this method, all
the calibration requirements of the applicable test method must also
be met.
3.2.1 Prepare the gas dilution system according to the
manufacturer's instructions. Using the high-level supply gas,
prepare, at a minimum, two dilutions within the range of each
dilution device utilized in the dilution system (unless, as in
critical orifice systems, each dilution device is used to make only
one dilution; in that case, prepare one dilution for each dilution
device). Dilution device in this method refers to each mass flow
controller, critical orifice, capillary tube, positive displacement
pump, or any other device which is used to achieve gas dilution.
3.2.2 Calculate the predicted concentration for each of the
dilutions based on the flow rates through the gas dilution system
(or the dilution ratios) and the certified concentration of the
high-level supply gas.
3.2.3 Introduce each of the dilutions from Section 3.2.1 into
the analyzer or monitor one at a time and determine the instrument
response for each of the dilutions.
3.2.4 Repeat the procedure in Section 3.2.3 two times, i.e.,
until three injections are made at each dilution level. Calculate
the average instrument response for each triplicate injection at
each dilution level. No single injection shall differ by more than
2 percent from the average instrument response for that
dilution.
3.2.5 For each level of dilution, calculate the difference
between the average concentration output recorded by the analyzer
and the predicted concentration calculated in Section 3.2.2. The
average concentration output from the analyzer shall be within
2 percent of the predicted value.
3.2.6 Introduce the mid-level supply gas directly into the
analyzer, bypassing the gas dilution system. Repeat the procedure
twice more, for a total of three mid-level supply gas injections.
Calculate the average analyzer output concentration for the mid-
level supply gas. The difference between the certified concentration
of the mid-level supply gas and the average instrument response
shall be within 2 percent.
3.3 If the gas dilution system meets the criteria listed in
Section 3.2, the gas dilution system may be used throughout that
field test. If the gas dilution system fails any of the criteria
listed in Section 3.2, and the tester corrects the problem with the
gas dilution system, the procedure in Section 3.2 must be repeated
in its entirety and all the criteria in Section 3.2 must be met in
order for the gas dilution system to be utilized in the test.

Appendixes N-O [Reserved]
Appendix P to Part 51--Minimum Emission Monitoring Requirements
1.0 Purpose. This appendix P sets forth the minimum requirements
for continuous emission monitoring and recording that each State
Implementation Plan must include in order to be approved under the
provisions of 40 CFR 51.165(b). These requirements include the
source categories to be affected; emission monitoring, recording,
and reporting requirements for those sources; performance
specifications for accuracy, reliability, and durability of
acceptable monitoring systems; and techniques to convert emission
data to units of the applicable State emission standard. Such data
must be reported to the State as an indication of whether proper
maintenance and operating procedures are being utilized by source
operators to maintain emission levels at or below emission
standards. Such data may be used directly or indirectly for
compliance determination or any other purpose deemed appropriate by
the State. Though the monitoring requirements are specified in
detail, States are given some flexibility to resolve difficulties
that may arise during the implementation of these regulations.
1.1 Applicability. The State plan shall require the owner or
operator of an emission source in a category listed in this appendix
to: (1) Install, calibrate, operate, and maintain all monitoring
equipment necessary for continuously monitoring the pollutants
specified in this appendix for the applicable source category; and
(2) complete the installation and performance tests of such
equipment and begin monitoring and recording within 18 months of
plan approval or promulgation. The source categories and the
respective monitoring requirements are listed below.
1.1.1 Fossil fuel-fired steam generators, as specified in
paragraph 2.1 of this appendix,
[[Page 5189]]
shall be monitored for opacity, nitrogen oxides emissions, sulfur
dioxide emissions, and oxygen or carbon dioxide.
1.1.2 Fluid bed catalytic cracking unit catalyst regenerators,
as specified in paragraph 2.4 of this appendix, shall be monitored
for opacity.
