Appendix D to Subpart UUUUU of Part 63 - PM CPMS Monitoring Provisions
40:16.0.1.1.1.8.214.29.46 : Appendix D
Appendix D to Subpart UUUUU of Part 63 - PM CPMS Monitoring
Provisions 1. General Provisions
1.1 Applicability. These monitoring provisions apply to
the continuous monitoring of the output from a PM CPMS, for the
purpose of assessing continuous compliance with an applicable
emissions limit in Table 1 or Table 2 to this subpart.
1.2 Summary of the Method. The output from an instrument
capable of continuously measuring PM concentration is continuously
recorded, either in milliamps, PM concentration, or other units of
measure. An operating limit for the PM CPMS is established
initially, based on data recorded by the monitoring system during a
performance stack test. The performance test is repeated annually,
and the operating limit is reassessed. In-between successive
performance tests, the output from the PM CPMS serves as an
indicator of continuous compliance with the applicable emissions
limit.
2. Continuous Monitoring of the PM CPMS Output
2.1 System Design and Performance Criteria. The PM CPMS
must meet the design and performance criteria specified in 40 CFR
63.10010(h)(1)(i) through (iii) and 40 CFR 63.10023(b)(2)(iii) and
(iv). In addition, an automated DAHS is required to record the
output from the PM CPMS and to generate the quarterly electronic
data reports required under section 3.2.4 of this appendix.
2.2 Installation Requirements. Install the PM CPMS at an
appropriate location in the stack or duct, in accordance with 40
CFR 63.10010(a).
2.3 Determination of Operating Limits.
2.3.1 In accordance with 40 CFR 63.10007(a)(3), 40 CFR
63.10011(b), 40 CFR 63.10023(a), and Table 6 to this subpart, you
must determine an initial site-specific operating limit for your PM
CPMS, using data recorded by the monitoring system during a
performance stack test that demonstrates compliance with one of the
following emissions limits in Table 1 or Table 2 to this subpart:
Filterable PM; total non-Hg HAP metals; total HAP metals including
Hg (liquid oil-fired units, only); individual non-Hg HAP metals; or
individual HAP metals including Hg (liquid oil-fired units,
only).
2.3.2 In accordance with 40 CFR 63.10005(d)(2)(i), you must
perform the initial stack test no later than the applicable date in
40 CFR 63.9984(f), and according to 40 CFR 63.10005(d)(2)(iii) and
63.10006(a), the performance test must be repeated annually to
document compliance with the emissions limit and to reassess the
operating limit.
2.3.3 Calculate the operating limits according to 40 CFR
63.10023(b)(1) for existing units, and 40 CFR 63.10023(b)(2) for
new units.
2.4 Data Reduction and Compliance Assessment.
2.4.1 Reduce the output from the PM CPMS to hourly averages, in
accordance with 40 CFR 63.8(g)(2) and (5).
2.4.2 To determine continuous compliance with the operating
limit, you must calculate 30-boiler operating day rolling average
values of the output from the PM CPMS, in accordance with 40 CFR
63.10010(h)(3) through (6), 40 CFR 63.10021(c), and Table 7 to this
subpart.
2.4.3 In accordance with 40 CFR 63.10005(d)(2)(ii), 40 CFR
63.10022(a)(2), and Table 4 to this subpart, the 30-boiler
operating day rolling average PM CPMS output must be maintained at
or below the operating limit. However, if exceedances of the
operating limit should occur, you must follow the applicable
procedures in 40 CFR 63.10021(c)(1) and (2).
3. RECORDKEEPING AND REPORTING.
3.1 Recordkeeping Provisions. You must keep the
applicable records required under 40 CFR 63.10032(b) and (c) for

Appendix D to Part 63 - Alternative Validation Procedure for EPA Waste and Wastewater Methods
40:16.0.1.1.1.46.325.36.125 : Appendix D
Appendix D to Part 63 - Alternative Validation Procedure for EPA
Waste and Wastewater Methods 1. Applicability
This procedure is to be applied exclusively to Environmental
Protection Agency methods developed by the Office of Water and the
Office of Resource Conservation and Recovery. Alternative methods
developed by any other group or agency shall be validated according
to the procedures in Sections 5.1 and 5.3 of Test Method 301, 40
CFR part 63, appendix A. For the purposes of this appendix, “waste”
means waste and wastewater.
2. Procedure
This procedure shall be applied once for each waste matrix.
Waste matrix in the context of this procedure refers to the target
compound mixture in the waste as well as the formulation of the
medium in which the target compounds are suspended. The owner or
operator shall prepare a sampling plan. Wastewater samples shall be
collected using sampling procedures which minimize loss of organic
compounds during sample collection and analysis and maintain sample
integrity. The sample plan shall include procedures for determining
recovery efficiency of the relevant compounds regulated in the
applicable subpart. An example of an acceptable sampling plan would
be one that incorporates similar sampling and sample handling
requirements to those of Method 25D of 40 CFR part 60, appendix
A.
2.1. Sampling and Analysis
2.1.1. For each waste matrix, collect twice the number of
samples required by the applicable regulation. Designate and label
half the sample vials the “spiked” sample set, and the other half
the “unspiked” sample set. Immediately before or immediately after
sampling (immediately after in the context of this procedure means
after placing the sample into the sample vial, but before the
sample is capped, cooled, and shipped to the laboratory for
analysis), inject, either individually or as a solution, all the
target compounds into each spiked sample.
2.1.2. The mass of each spiked compound shall be 40 to 60
percent of the mass expected to be present in the waste matrix. If
the concentration of the target compounds in the waste are not
known, the mass of each spiked compound shall be 40 to 60 percent
of the limit allowed in the applicable regulation. Analyze both
sets of samples (spiked and unspiked) with the chosen method.
3. Calculations
For each pair of spiked and unspiked samples, determine the
fraction of spiked compound recovered (R) using the following
equations.
where: mr = mass spiked compound measured (µ g). ms = total mass of
compound measured in spiked sample (µ g). mu = total mass of
compound measured in unspiked sample (µ g). where: S = theoretical
mass of compound spiked into spiked sample (µ g).
3.1. Method Evaluation
In order for the chosen method to be acceptable for a compound,
0.70≤R≤1.30 (R in this case is an average value of all the spiked
and unspiked sample set R values). If the average R value does not
meet this criterion for a target compound, the chosen method is not
acceptable for that compound, and therefore another method shall be
evaluated for acceptance (by repeating the procedures outlined
above with another method).
3.2. Records and Reports
Report the average R value in the test report and correct all
reported measurements made with the method with the calculated R
value for that compound by using the following equation:
3.3. Optional Correction Step
If the applicable regulation allows for correction of the mass
of the compound in the waste by a published fm value, multiply the
reported result calculated above with the appropriate fm value for
that compound.
