II. Summary of Petitioned-For Tolerance

    In the Federal Register of May 23, 2014 (79 FR 29729) (FRL-9910-
29), EPA issued a document pursuant to FFDCA section 408(d)(3), 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP
3F8214) by FMC Corporation, 1735 Market St., Philadelphia, PA 19103.
The petition requested EPA to amend the tolerances in 40 CFR 180.418
for residues of the insecticide zeta-cypermethrin, S-cyano (3-
phenoxyphenyl) methyl ())(cis-trans 3-(2-2-
dichloroethenyl)-2,2 dimethylcyclopropanecarboxylate, in or on alfalfa,
forage from 5.0 parts per million (ppm) to 15.0 ppm and alfalfa, hay
from 15.0 ppm to 30.0 ppm. That document referenced a summary of the
petition prepared by FMC Corporation, the registrant, which is
available in the docket, http://www.regulations.gov. Comments were
received on the notice of filing. EPA's response to these comments is
discussed in Unit IV.C.
    Instead of the proposed tolerances in alfalfa hay at 30.0 ppm and
alfalfa forage at 15.0 ppm, EPA is establishing these tolerances at 30
ppm and 15 ppm, respectively. The Agency establishes tolerances using
whole numbers for tolerances of 10 ppm or more, per the Organization
for Economic Cooperation and Development (OECD) User Guide ENV/JM/
MONO(2011)2 for the OECD tolerance calculation procedure.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
.''
    Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for zeta-cypermethrin including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with zeta-
cypermethrin follows.
    Zeta-cypermethrin is an enriched isomer of the pyrethroid
insecticide cypermethrin. In addition, alpha-cypermethrin is also an
enriched isomer of cypermethrin. Although cypermethrin, alpha-
cypermethrin, and zeta-cypermethrin are separate active ingredients
with different end-use products, they are included together in the
hazard evaluation for the purpose of human health risk assessment. The

toxicology database for the cypermethrins includes studies with
cypermethrin and both of its enriched isomers, and is considered
complete for the purpose of risk assessment.
    The aggregate risk assessment for zeta-cypermethrin must consider
potential exposure from all cypermethrins (i.e., cypermethrin, alpha-
cypermethrin, and zeta-cypermethrin), since the three active
ingredients are considered to be essentially the same from the
mammalian toxicity perspective. The revised tolerances associated with
the increased use rate on alfalfa forage and hay have no impact on the
existing dietary exposure assessment for the cypermethrins. Alfalfa
forage and hay are livestock feed items that are not directly entered
into the dietary exposure assessment. In addition, the increased
tolerances in the alfalfa forage and hay will not have an impact on the
existing livestock commodity tolerances; these tolerances were
established at levels determined largely due to the potential for
residues in other commodities (such as clover and trefoil) with higher
tolerances and which also constitute a greater percentage of the
estimated livestock diet for zeta-cypermethrin. Therefore, the proposed
increased use rates on alfalfa grown for hay and forage will not result
in the need to increase the tolerances in livestock commodities.
Consequently, the previously conducted dietary exposure assessment will
not be affected by the proposed increased use rate and corresponding
tolerances for alfalfa hay and forage. Furthermore, the drinking water
estimates used in the existing dietary exposure assessment are more
protective (higher) than those recently estimated based on the proposed
use pattern and using updated drinking water models.
    In the final rule published in the Federal Register of December 7,
2012 (77 FR 72975) (FRL-9371-7), EPA established tolerances for
residues of zeta-cypermethrin in multiple commodities. Since the
publication of that final rule, the toxicity profile of zeta-
cypermethrin has not changed and since the revised tolerances
associated with the increased use rate on alfalfa forage and hay have
no impact on the existing dietary and aggregate risk determinations,
the risk assessments that supported the establishment of the zeta-
cypermethrin tolerances published in the December 7, 2012 Federal
Register final rule remain valid. Therefore, EPA is relying on those
risk assessments in order to support the revised tolerances for zeta-
cypermethrin in alfalfa forage and hay.
    An updated aggregate risk assessment was not needed to support the
proposed increased tolerances for residues in alfalfa forage and hay,
since these are livestock feed items, and the increased tolerances will
not result in a change in the previously estimated dietary (food and
water) or residential exposure estimates for zeta-cypermethrin. For a
detailed discussion of the aggregate risk assessments and determination
of safety, please refer to the December 7, 2012 Federal Register final
rule and its supporting documents, available at http://www.regulations.gov in docket ID number EPA-HQ-OPP-2010-0472. EPA is
also relying on those supporting risk assessments and findings to
support of this final rule.
    Based on the risk assessments and information described in this
unit, EPA concludes that there is a reasonable certainty that no harm
will result to the general population, or to infants and children from
aggregate exposure to zeta-cypermethrin residues. Further information
can also be found in the document: ``Zeta-Cypermethrin--Human Health
Risk Assessment to Support Increased Tolerances and Use Rate on Alfalfa
Hay and Forage'' in docket ID number EPA-HQ-OPP-2014-0210.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate tolerance enforcement methods are available in Pesticide
Analytical Manual (PAM) Volume II for determining residues of alpha-
cypermethrin, cypermethrin, and zeta-cypermethrin in plant (Method I)
and livestock (Method II) commodities. Both methods are gas
chromatographic methods with electron-capture detection (GC/ECD), and
have undergone successful Agency petition method validations (PMVs).
These methods are not stereospecific; thus no distinction is made
between residues of cypermethrin (all 8 stereoisomers), alpha-
cypermethrin (enriched in 2 isomers), and zeta-cypermethrin (enriched
in 4 isomers). The January 1994 Food and Drug Administration (FDA)
PESTDATA database (PAM Volume I) indicates that residues of
cypermethrin are completely recovered (>80%) using multi-residue method
sections 302 (Luke), 303 (Mills, Onley, and Gaither), and 304 (Mills
fatty food).

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
    Currently established U.S. tolerances for cypermethrin, alpha-
cypermethrin, and zeta-cypermethrin are included in the same part in
title 40 of the Code of Federal Regulations (CFR), but have separate
sections and different crops listed. There are multiple Codex MRLs for
zeta-cypermethrin, but all are in conjunction with MRLs for total
cypermethrin isomers (no MRLs have been established solely for zeta-
cypermethrin). However, although the definitions differ formally, they
are effectively harmonized since the tolerance-enforcement methods are
not stereospecific, and thus do not distinguish between residues of
cypermethrin, alpha-cypermethrin, and zeta-cypermethrin. For
enforcement purposes, the same moiety is being regulated.
    There is a Codex MRL established in alfalfa fodder at 30 ppm, which
would be harmonized with the proposed tolerance in alfalfa hay. Codex
has not established an MRL in alfalfa forage.

C. Response to Comments

    One comment was received from the general public urging the Agency
to tighten regulations for pesticides tolerances and uses. The
commenter particularly addressed carcinogenic chemicals and their
effects on children's health.
    Cypermethrin is classified as a ``Possible human carcinogen'' based
on the presence of benign tumors (lung adenomas) in an adequate mouse
carcinogenicity study with cypermethrin. The presence of common benign
tumors (lung adenomas), in one species (mice) and one sex (female),
with no increase in the proportion of malignant tumors or decrease in
the time-to-tumor occurrence, together with the lack of mutagenic
activity, was not considered strong enough to warrant a linear or no-
threshold approach to quantitation of human cancer risk. Quantification
of risk using a non-linear

approach (i.e., acute population adjusted dose (aPAD), acute reference
dose (aRfD)) will adequately account for all chronic toxicity,
including carcinogenicity that could result from exposure to
cypermethrin. The Agency is using the acute dietary endpoint because,
due to the rapid reversibility of the most sensitive neurotoxicity
endpoint used for quantifying risks, there is no increase in hazard
with increasing dosing duration; therefore, the acute dietary endpoint
is protective of the endpoints from repeat dosing studies, including
cancer dietary exposures.
    No evidence of carcinogenicity was observed in carcinogenicity
studies in rats with cypermethrin or in mice with alpha-cypermethrin.
Carcinogenicity studies are not available for zeta-cypermethrin;
however, based on the structural and toxicological similarities to
alpha cypermethrin and cypermethrin the carcinogenic potential is
expected to be similar. Therefore, the Agency considers conclusions
regarding the carcinogenic potential of cypermethrin to be applicable
to alpha-cypermethrin and zeta-cypermethrin.
    The Agency has considered all the available data, including all
available data concerning the potential for carcinogenicity and
concluded after conducting a risk assessment, that there is a
reasonable certainty that no harm will result from aggregate human
exposure to zeta-cypermethrin. EPA gives special consideration to the
potential susceptibility and exposures of infants and children to
pesticide chemical residues and is confident that it has chosen
endpoints, points of departure, and uncertainty factors that are
protective for all populations, including infants and children, and
that have a strong scientific foundation. In addition, there are
ongoing efforts to develop data to gain more information concerning the
potential sensitivity of infants and young children to pyrethroids as a
class.

V. Conclusion

    Therefore, tolerances are amended for residues of zeta-
cypermethrin, S-cyano(3-phenoxyphenyl)methyl ())(cis-
trans3-(2-2-dichloroethenyl)-2,2dimethylcyclopropanecarboxylate,
including its metabolites and degradates in or on alfalfa, forage at 15
ppm and alfalfa, hay at 30 ppm.

VI. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA section 408(d) in
response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
    This action directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this action. In addition, this
action does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
(UMRA) (2 U.S.C. 1501 et seq.).
    This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).

    DRAFT VERSION FOR COMMENT ONLY - NOT INTENDED FOR FIELD IMPLEMENTATION

                      DRAFT PERFORMANCE SPECIFICATION ??
PERFORMANCE SPECIFICATION FOR HCl CONTINUOUS EMISSION MONITORING SYSTEMS IN STATIONARY SOURCES

1.0 Scope and Application.

0.1 Analytes. This performance specification is applicable for measuring gaseous concentrations of HCl on a continuous basis in the units of the applicable standard or in units that can be converted to units of the applicable standard(s) regulated under Title III of the 1990 Clean Air Act Amendments. The specification includes requirements for initial acceptance including (1) instrument accuracy and (2) stability assessments.

0.2 Applicability. A source that demonstrates their continuous emission monitoring system (CEMS) meets the criteria of this performance specification may use the system to continuously monitor gaseous hydrogen chloride (HCl). If your HCl CEMS is capable of reporting the HCl concentration in the units of the existing regulation, no additional CEMS components are necessary. If your HCl CEMS does not report concentrations in the units of the existing standard, then other CEMS components (e.g., oxygen, temperature, and pressure) are necessary to convert the units reported by your HCl CEMS to the units of the standard. This specification is not designed to evaluate the installed CEMS performance over an extended period of time. The Administrator may require the operator under Section 114 of the Act, to conduct CEMS performance evaluations at other times besides the initial test to evaluate the CEMS performance. See 40 CFR Part 60, §60.13(c).

1.0 Summary of Performance Specification.

0.1 This specification covers two basic topics: (1) the instrument requirements for an HCl CEMS and (2) the requirements that each HCl CEMS must meet during the performance specification test.

0.2 The technology used to measure gaseous HCl must provide a distinct response and address any appropriate interference correction(s). It must accurately measure HCl in a representative sample (path or point sampling) of stack effluent.

0.3 Relative accuracy (RA) may be established against a reference method. Alternatively, accuracy tests require a secondary source of certified calibration standard which is spiked through the sampling probe.

0.4 Calibration drift and calibration error tests are also required.

3.0 Definitions.

 3.1 Batch Sampling occurs when a gas cell is alternately filled and evacuated and a measurement of each cell fill is performed.

 3.2 Calibration Cell is a gas containment cell that is placed in the optical path of a CEM instrument to perform precision and bias checks. The cell can be evacuated and purged to remove calibration gas. When charged it contains a known concentration of HCl calibration gas.

 3.3 Calibration Drift (CD) is the difference in the CEMS output readings between the established reference value and the output after a stated period of operation during which no unscheduled maintenance or adjustment took place. A separate CD determination must be performed for the pollutant and diluent analyzers in concentration and for the CEMS in the units of the emission standard.

 3.4 Calibration Error (CE) is the mean difference between the concentration indicated by the CEMS and the known concentration generated by a calibration source, divided by the span, when the entire CEMS, including the sampling interface is challenged. A CE test is performed to document the accuracy of the CEMS.

 3.5 Centroidal Area means a concentric area that is geometrically similar to the stack or duct cross section and is no greater than 1 percent of the stack or duct cross-sectional area.

 3.6 Certified Gas Standard: is a EPA protocol compressed gas standard with known concentration certified by the supplier to be accurate to  2 percent of the value. Note: If protocol gas standards are not available vendor supplied compressed gas standards certified to be accurate to  2 percent of the value may be used.

 3.7 Constant emissions occurs when the composition of the emissions remains stable within 5% over a measurement cycle so that a single analytical procedure and instrument algorithm or program is suitable for analyzing all of the sample spectra.

 3.8 Continuous Emission Monitoring System (CEMS) means the total equipment required for the determination of a gas concentration or emission rate as a continuous operation. The sample interface, pollutant analyzer, diluent supply/analyzer, and data recorder can be major subsystems of the CEMS.

 3.9 Continuous Operation is the time between periodic maintenance when an instrument and sampling system operates without user intervention, continuously samples flue gas, records measurement data, analyzes the data for HCl, and saves the results to a computer file. User intervention is permitted for initial set-up of sampling system, initial calibrations, and periodic maintenance.

 3.10 Continuous Sampling occurs when sample gas is continuously flowing through a measurement path. Measurements of the flowing sample are made at regular intervals.

 3.11 Data Recorder is the portion of the CEMS that provides a record of analyzer output. The data recorder may record other pertinent data such as effluent flow rates, various instrument temperatures or abnormal CEMS operation.

 3.12 Diluent Analyzer means that portion of the CEMS that senses the diluent gas (e.g., O2) and generates an output proportional to the gas concentration.

 3.13 Dynamic Spiking is the procedure used to document the precision and bias of the CEMS by quantitatively spiking a certified gas into the measurement system while sampling.

 3.14 Gas Cell. For extractive CEMS, a gas containment cell that can be evacuated. It contains the sample enabling the optical beam to pass from the instrument through the sample, and to the detector. The gas cell may have multi-pass optics depending on the required detection limit(s) for the application.

 3.15 High-level drift is the absolute difference between a high-level calibration gas and the CEMS response over a specified period of time divided by the span in units of the applicable standard.

 3.16 Independent Measurement means two independent one minute averages of CEMS data taken during sample gas analysis separated by a complete flush of the measurement system with sample gas.

            3.16.1 For continuous flow extractive measurement systems the interval between independent measurements must be sufficient to pass at least 7 measurement cell volumes of sample gas through the system. Estimate the residence time empirically by: (1) filling the system to ambient pressure with a known analyte concentration gas standard, (2) measuring the gas standard, (3) purging the system with zero gas at the sampling rate and performing a measurements until the gas standard is less than or equal to twice the system detection limit (LOD).

            3.16.2 For in-situ optical systems, independent measurements are separated by the time required to obtain a single one-minute average measurement.

 3.17 Interference is a compound or material in the sample matrix whose characteristics bias the instrument signal (positively or negatively). The interference may not prevent the sample measurement, but could increase the analytical uncertainty in the measured concentration.

 3.18 Instrument Measurement Range is the range of concentrations the instrument can reliably measure from the lowest concentration to the span.

 3.19 Intercept is the average instrument response at zero HCl concentration.

 3.20 Integrated Path Sampling CEMS (IPS-CEMS) is a CEMS that samples the source effluent along a path greater than 10 percent of the equivalent diameter of the stack or duct cross section.

 3.21 Level of Detection (LOD) is defined by the procedure in Section 15 of Method 301. The LOD is specific to the measured test gas matrix. The LOD is a calculated value and must be determined before conducting a test to ascertain whether the technique can meet the sensitivity requirements of the CEMS data.

 3.22 Linear Regression is a method of finding a mathematical formula that relates two variables (e.g., concentration and instrument response) that are linearly related.

 3.23 Path Length. For extractive CEMS, the distance in meters of the optical path within the gas measurement cell. For cross stack IPS-CEMS, the distance in meters of the optical path that passes through the sample gas.

 3.24 Point Sampling CEMS is a CEMS that samples the source effluent at a single point.

 3.25 Pollutant Analyzer means that portion of the CEMS that senses quantifies and generates an output proportional to the stack gas HCl concentration.

 3.26 Reference Analyzer is an instrument with a separate sampling and sample conditioning system that can be used for comparison measurements such as stratification tests.

 3.27 Reference Value (R) is the certified concentration of a vendor supplied gas or the known concentration of a generated calibration gas in ppmv. For in-situ integrated path (IP) CEMS, the reference value will be calculated such that, when introduced into the optical path of the CEMS, will provide the equivalent concentration at the stack temperature, pressure, and line strength factor (at the stack temperature). The line strength factor is derived from the HITRAN database.

 3.28 Relative Accuracy is the absolute mean difference determined by the CEMS between a) the gas concentration spiked through the sampling probe and the certified value of the spiked gas divided by the certified spike gas concentration or b) the reference method (RM) plus the 95 percent confidence coefficient divided by the average RM value or the applicable emission standard.

 3.29 Relative Response Factor (RRF) the response of an instrument detector to an analyte compared to the known concentration of a standard gas.

            8.0 CEMS Installation and Measurement Location Specifications

              8.1 CEMS Installation.

  0.6.1 Install the CEMS at an accessible location where HCl measurements are representative. Select a representative measurement point or path for monitoring in locations that avoid gas stratification as described in Section 11.5.

  0.6.2 You may locate the instrumental analyzer portions of your HCl CEMS any distance from the sampling point provided the transmission efficiency from the sampling point to the instrumental analyzer point meets the criteria outlined in Section 11.6.

              2.1 Measurement Location.

  0.6.3 The sampling location of the HCl CEMS should be downstream of all pollution control equipment at a position where the HCl concentration is directly representative of total emissions from the stationary source.

  0.6.4 You may use either point or integrated path sampling technology.

                              <IP_ADDRESS> For a path integrated sampling CEMS the effective measurement path must be:

                                    <IP_ADDRESS>.1 Totally within the inner area bounded by a line 1.0 meter from the stack or duct wall, or

                                    <IP_ADDRESS>.2 Have at least 70 percent of the path within the inner 50 percent of the stack diameter or duct cross section, or be centrally located over any part of the stack or duct centroid area.

            7.0 Quality Control.

              7.1  The CEMS operating range (zero to span) must encompass the response of the HCl CEMS for all expected HCl concentrations, including the applicable emission limit, if practicable.

              7.2  All CEMS must operate continuously without repairs, unscheduled maintenance, or non-routine adjustments during the performance specification tests to determine calibration drift, error, and RA.

            8.0 Calibration and Standardization

              8.1 The source owner or operator is responsible to calibrate, maintain, and operate the CEMS properly.

              8.2  The calibration error test and seven day drift test must be performed by flooding calibration gas through the sampling probe for this performance specification.

              8.3 Limit of Detection (LOD) Determination. You must determine the instrument specific LOD following the procedure in Section 15 of Method 301. This is accomplished by measuring the standard deviation of a calibration gas standard within 2 times the expected LOD or by measuring the noise limited instrument signal with no additional HCl spike. You may not use a CEMS whose LOD is greater than 20 percent of the regulatory limit or the intended use of the data.

            9.0 Performance Specification Test Procedure.

              9.1 The performance testing is used for initial validation upon installation of a new system. After completing the CEMS installation, setup and calibration you must complete the test procedures in this section.

              9.2 Validation is performed by meeting the RA requirements against a reference method or by dynamically spiking certified HCl gas standards through the sampling probe. Note: Figure 3 provides an overview of a typical dynamic spiking arrangement.

              9.3 Pretest Preparation

  0.6.5 Prior to the start of your initial performance specification tests, you must ensure that the HCl CEMS is installed according to the manufacturer's specifications and the requirements in Section 8.

  0.6.6 After the installation, we recommend you check the zero and high-level drift as described in Section 11.8 and the calibration error as described in Section 11.7 to verify that the instrument is functioning properly.

              6.1  CEMS and Data Recorder Scale Check

  0.6.7 Record and document the measurement range of the HCl CEMS. The CEMS operating range (zero to span) and the range of the data collection device must encompass all expected HCl concentrations and the applicable emission limit, if practicable. The CEMS and data collection device output range must include zero and the span value.

              7.1 Stratification Test

A stratification test must be conducted when the facility is operating during normal operation. The purpose of this test is to verify that excess stratification of the target pollutant does not render sampling point of the CEMS non-representative.

  0.6.8 If an isokinetic reference method (RM) is used for the RA testing required in section 11.8.3 you may determine whether effluent stratification exists using a CEMS while traversing the stack following the requirements in 40 CFR Part 60 Method 1.

                              <IP_ADDRESS> One probe, located at the stack or duct centroid, is used as a stationary reference point to measure the change in the effluent concentration over time (Ci).

                              <IP_ADDRESS> The second probe is used to determine the concentration over the traverse points specified in Method 1 (Cref). The traverse points are sampled for a minimum of five minutes at each point or as required by the reference method. You may test for stratification using either:

a)	Velocity tests as described in Method 2,
b)	HCl concentrations using Method 320 or
c)	an acceptable alternative (i.e., Method 10 for CO or Method 7E for NOx).

                              <IP_ADDRESS> Select traverse points that assure acquisition of representative samples over the stack or duct cross section" (40 CFR 60 Appendix B PS2 Section <IP_ADDRESS>).

                              <IP_ADDRESS> To determine stratification, compare the fixed reference CEMS effluent concentrations (Ci) to the reference method effluent concentration, (Cref), using Eq. 1. You must identify and use a fixed sampling location where the percent stratification differences, St, is within 10% of the reference method.

  0.6.9 If dynamic spiking is used for the determination required in section 11.8.4 you may determine whether effluent stratification exists using a dual probe system and two identical HCl CEMS.  One probe is used to make HCl measurements at a fixed reference point and the second is used to make HCl measurements of effluent concentration at each traverse point as specified in 40 CFR Part 60 Method 1. Both systems must be prequalified following the requirements in Section 11.5 before testing.

                              <IP_ADDRESS> Install a temporary CEMS equivalent to the permanent installation. The second CEMS must allow sampling while traversing the stack or duct following 40 CFR Part 60 Method 1.
                              <IP_ADDRESS>  Use the HCl CEMS and the first probe to make measurements at the CEMS fixed reference point (e.g., at the stack or duct centroid).

                              <IP_ADDRESS> Use the temporary equivalent CEMS and the second probe to make measurements of effluent concentration at each traverse point as specified in 40 CFR Part 60 Method 1.

                              <IP_ADDRESS> To determine stratification, compare the fixed probe effluent concentration, (Ci) to the measurements of the traverse points, (Cref) using Eq. 1. You must identify and use a fixed sampling location where the percent stratification differences, St, is within 10% of the reference method measurement.

  6.6 Response Time Determination

1.0.1 Determine the average upscale and downscale response times from three repetitions of each test. You will report the greater of the average upscale or average downscale response times as the response time for the system.

      <IP_ADDRESS> Determine the upscale response time by injecting zero gas into the measurement system at the probe inlet.

      <IP_ADDRESS> When the system output has stabilized (no change greater than 1 percent of full scale for 30 sec), introduce an upscale calibration gas and wait for a stable value.

      <IP_ADDRESS> Record the time (upscale response time) required to reach 95 percent of the final stable value.

      <IP_ADDRESS> Next, reintroduce the zero gas and record the time required to obtain a stable downscale response time (Section <IP_ADDRESS>).

      <IP_ADDRESS> For CEMS that perform a series of operations, (purge-blow back, sample, analyze, etc.) you must time the injection of calibration gases to produce the longest response time.

      <IP_ADDRESS> Repeat the entire procedure three times and determine the mean upscale and downscale response times. The slower or longer of the two means is the system response time.

2.0.2 The HCl CEMS must complete one cycle of operation (sampling, analyzing, and data recording) at least once every 15-minutes, (i.e., a minimum of four samples per hour).

  2.6 Calibration Error Check

3.0.3 The percent calibration error is the mean difference between the certified HCl calibration gas value, (R), and the CEMS response at each calibration point, (A), calculated using Eq. 2. Calibration Error must be less than 5 percent of CEMs span.

4.0.4 Calibration curves, (linear or quadratic) must demonstrate an intercept equal to or less than 15 percent of the instrument span.

5.0.5 Extractive CEMS calibration error check is performed by flooding the probe and instrument with known concentrations of HCl gas.

      <IP_ADDRESS> Vendor certified HCL calibration gas is introduced at a minimum of three levels (low, mid, high). Refer to Table 1 for required calibration gas levels. Verify that the measurement is stable by collecting two consecutive independent measurements, at least 2 minutes apart.

      <IP_ADDRESS> The percent relative difference of the reference gas concentration to the measured concentration may not exceed 10 percent. Table 1 provides guidance on the certified HCl concentrations for use as low-, mid-, and high levels.

6.0.6 In-situ, cross stack CEMS calibration check is performed by addition of known concentrations of HCl gas into a calibration cell of known volume and path length. Calculate the equivalent concentration of the Vendor certified HCl calibration gas at the stack conditions.

  6.6 Calibration Drift (CD) Test

7.0.7 Prior to the start of the initial accuracy tests, you must begin a calibration drift test for a period of seven consecutive days.

8.0.8 The calibration drift test must be conducted during normal facility operations. The purpose of this test is to verify that the instrument operation is stable.

9.0.9 The calibration drift tests must be performed using certified calibration gases or a NIST traceable calibration transfer standard.

10.0.10 High concentration certified standard may be diluted and used to measure high-level calibration drift. Use of this method requires documenting the quantitative introduction of HCL gas into the system; such as a Method 205 or similar procedure.

11.0.11 During the calibration drift test period you must determine the magnitude of the zero-level calibration drift and the high-level calibration drift at least once each day (at 24-hour intervals)using Eq. 2.

12.0.12 During the intervals between drift tests, no adjustments or calibrations may be made to the CEMS. If periodic automatic or manual adjustments are made to the CEMS zero-level and calibration settings, conduct the CD test immediately before these adjustments, or conduct it in such a way that the CD can be determined.

13.0.13 For Extractive CEMS, determine the zero-level drift by introducing certified zero gas into the CEMS sampling probe (24 hours after the last calibration or calibration drift test). Record the CEMS response. Determine the high level calibration drift by introduction certified calibration gas into the CEMS sampling probe. (24 hours after the last calibration or calibration drift test). Record the CEMS response.

14.0.14 For IP-CEMS, calibration drift checks, introduce certified zero or calibration gas into a permanently mounted calibration cell located in the optical path of the instrument Verify that the measurement is stable by collecting two consecutive independent measurements, at least 2 minutes apart. Calculate the equivalent reference value, Ri, at the stack conditions. See section 12.1 for nomenclature of Ri.

15.0.15 The zero-level and high-level drift each must be less than 5% of span for each of seven consecutive days. Each zero- and high-level drift check must be recorded daily and reported for the seven day drift check tests.

  15.6 Accuracy Test

16.0.16  The accuracy of the HCl CEMS may be determined by performing either a relative accuracy comparison to a reference method or by dynamic spiking.

17.0.17 Sampling Strategy for RM Tests. Conduct the RM tests in such a way that they will yield results representative of the emissions from the source and can be correlated to the CEMS data. Conduct the diluent (if applicable), moisture (if needed), and pollutant measurements simultaneously. However, diluent and moisture measurements that are taken within an hour of the pollutant measurements may be used to calculate dry pollutant concentration and emission rates. In order to correlate the CEMS and RM data properly, record the beginning and end of each RM  run (including the exact time of day) with the permanent record of CEMS output.

18.0.18 Conduct the RA test while the affected facility is operating during normal operation, or as specified in an applicable subpart.

19.0.19 Relative Accuracy Using a Reference Method

      <IP_ADDRESS> Reference Methods (RM). Unless otherwise specified in an applicable subpart of the regulations, Methods 26A or Method 320, or their approved alternatives, are the reference methods for HCl. Other reference methods for moisture, oxygen, etc. may be necessary.

      <IP_ADDRESS>  Number of RM Tests. Conduct a minimum of nine sets of all necessary RM test runs.

NOTE: More than nine sets of RM tests may be performed. If this option is chosen, a maximum of three sets of the test results may be rejected so long as the total number of test results used to determine the RA is greater than or equal to nine. However, all data must be reported, including the rejected data.

      <IP_ADDRESS> Correlation of RM and CEMS Data. Correlate the CEMS and the RM test data as to the time and duration by:

(a). Determining from the CEMS final output of the integrated average pollutant concentration or emission rate for each pollutant RM test period. Consider system response time, if important, and confirm that the pair of results are on a consistent moisture, temperature, and diluent concentration basis and

(b). Comparing each integrated CEMS value against the corresponding average RM value.

      <IP_ADDRESS> If the RM has an integrated sampling technique (e.g., Method 320), make a direct comparison of the RM results and CEMS integrated average value for each test period.

      <IP_ADDRESS> Calculate the mean difference between the RM and CEMS values in the units of the emission standard, the standard deviation, the confidence coefficient, and the relative accuracy according to the equations in Section 12.

20.0.20  Accuracy Determination Using Dynamic Spiking

      <IP_ADDRESS> Dynamic spiking may be used to determine and document the accuracy, precision, and bias of the HCl CEMS. Figure 3 provides an overview of a typical dynamic spiking arrangement.

      <IP_ADDRESS> To meet the dynamic spiking criteria, you must perform validation of your HCl CEMS by measuring spiked and unspiked sample gas. You must introduce the spike gas into the permanent CEMS probe, upstream of the particulate filter and as close to the sampling head as practical. A known quantity of calibration gas is spiked into the sample gas and measured by the CEMS during normal facility operation.

Note: For cases where the emission standard is expressed in units of lb/MM Btu or corrected to a specified O2 or CO2 concentration, an absolute accuracy specification equivalent to 5 ppm must be calculated using an average or typical diluent concentration and applicable conversion factors. The appropriate procedures for use in cases where a percent removal standard is more restrictive than the emission standard are the same as in PS-2.

      <IP_ADDRESS> Dynamic Spiking Procedure for Extractive CEMS

<IP_ADDRESS>.1	You must collect at least 6 sets of 1 minute average independent parallel unspiked and spiked sample measurements evenly spaced over no less than an hour for a complete accuracy test.

<IP_ADDRESS>.2	The HCl concentration of the flue gas must be determined during each spiking trial.

<IP_ADDRESS>.3 Install a temporary CEMS equivalent to the permanent installation that can perform a stack traverse.  You may use this system to confirm that stratification of HCL meets the requirements of Method 11.5.

<IP_ADDRESS>.4 Begin collecting measurements of 2 independent unspiked samples with the temporary CEMS and two spiked sample measurements with the permanent CEMS.

<IP_ADDRESS>.5 While the permanent HCl CEMS is sampling flue gas, HCl reference gas at the regulatory standard or at five times the LOD is introduced into the CEMS sample interface using a mass flow controller (or equivalent).

<IP_ADDRESS>.6 Introduce the spike gas into the back of the probe, upstream of the particulate filter. Collect measurement data from the spiked gas stream until sequential measurements are within 5% of each other. Then collect measurements of 2 independent spiked samples.

<IP_ADDRESS>.7 The target ratio of the flue gas sampling rate (Qs) to the HCl reference gas is > 9:1. The HCl concentration is quantified by the HCl CEMS.

<IP_ADDRESS>.8 Turn off the spike flow and collect data until sequential unspiked measurements are within 5% of each other.

<IP_ADDRESS>.9 Repeat the procedure in <IP_ADDRESS>.1 through <IP_ADDRESS>.8 a minimum of 6 times. Simultaneously collect data from the temporary unspiked monitoring system.

<IP_ADDRESS>.10  Calculate the dilution ratio of certified gas to stack gas using either:

(1) quantitative introduction of the HCl calibration gas with total flow measurement or

(2) a dynamically spiked tracer in the HCl calibration gas.

<IP_ADDRESS>.11 Total probe flow measurement requires measurement of HCl spike flow plus total flow through the instrument detector.

<IP_ADDRESS>.12 Measure the spike gas flow and the total flow with a calibrated flow monitor capable of NIST traceable 2 percent accuracy. Use of this method requires documenting the quantitative introduction of HCl gas into the system such as a Method 205 or similar procedure.

<IP_ADDRESS>.13 You may use a tracer gas to determine the dilution ratio and amount of spike as an alternative and you must measure tracer gas flow to an accuracy of 2 percent.

<IP_ADDRESS> Dynamic Spiking Procedure for Integrated Path CEMS.

<IP_ADDRESS>.1	For in-situ IP-CEMS, you must perform an accuracy test using a calibration cell mounted in the optical path of the instrument. Fill the calibration cell in the optical path with a calibration gas at the regulatory limit or five times the LOD. Sequential measurements are performed with calibration gas and zero gas in the calibration cell.

         <IP_ADDRESS> Analyze the results from the dynamic spiking relative accuracy tests using equations in Sections 12. Calculate the mean difference between the instrument response and the reference value (certified gas) for each injection using Eq. 3 and 4. Calculate the equivalent reference value, Ri at the stack conditions. The RA for the average of three independent measurements may not exceed 15 percent of span.

<IP_ADDRESS>.1 If the statistical analysis passes the validation criteria, then the accuracy evaluation is completed.

Note: If the results do not pass the criteria, temporal variations in the sample gas may be excessive relative to the interval between measurements. Temporal variation may be reduced by:
          *       Averaging the measurements over long sampling periods and using the averaged results in the statistical analysis,

          *       Reducing the total system response time for extractive CEMS sampling systems, for example, using a smaller volume cell or increasing the sample flow rate.

          *       Using two separate sampling lines (and pumps) for extractive CEMS; one line to carry unspiked flue gas and the other line to carry spiked flue gas to decrease the equilibration time in the lines. Both sampling lines include independent flow measurement and are continuously purged. Even with two sampling lines the variation in unspiked concentration may be fast compared to the interval between consecutive measurements.

  20.10 Reporting

1.0.1 Record and summarize in tabular form the results of the calibration drift, response time, calibration error, and RA test or alternative spiking procedure, as appropriate. Include all data sheets, calculations, CEMS data records (i.e., charts, records of CEMS responses), and cylinder gas or reference material certifications necessary to confirm that the performance of the CEMS met the performance specifications.

2.0.2 Record and report supporting dilution system data including standard cylinder gas flow, total gas flow, and the results of the test measurements.

3.0.3 You must check with the appropriate regional office, State, or Local agency for additional requirements, if any.

4.0.4 5.0.5 All data and records associated with the HCl CEMS performance acceptance must be retained for 5 years.

0.5 Relative Accuracy using Dynamic Spiking Test Data. If quantitative HCl calibration gas introduction and total flow was used to calculate reference HCl challenge concentration, calculate the accuracy and precision of the HCl CEMS measurements, the correlation between the HCl challenge gas concentration (HClref) and the average measured HCl concentration (HClmeas) is determined as follows:

1.0.1 Calculate the arithmetic mean difference of the one minute RA measurements using equation 4.

				davg= 1ndi  			Eq. 4

where:
				di= Ri-yi 			Eq. 5

For in-situ IP-CEMS, use equation 5a.

				di=HCl - ref-yi			Eq. 5a

2.0.2 Calculate the standard deviation of the differences (Sd) of measured and reference method results calculated using equation 6.

			Sd=1ndi2-1ndin2n-11/2			Eq. 6

3.0.3 Calculate the confidence coefficient, (CC) for the relative accuracy tests using equation 7.

			CC=t0.975*Sdn1/2 			Eq. 7

4.0.4 Calculate the relative accuracy (RA) for the CEMS using equation 8.

	RA=davg+CC/RMavg*100		Eq. 8

0.4 Relative Response (RRF). Calculated RRF using equation 9.

		RRF= (yi)(Ri) 					Eq. 9

      12.0 Method Performance

0.1 Calibration drift for the HCl CEMS must not drift or deviate from the reference value of the gas cylinder by more than 5 percent of the span value for 7 consecutive days (Eq. 2).

0.2 Calibration Error Check, (linear or quadratic)

      <IP_ADDRESS> Calibration intercept must be equal to or less than 15% of the instrument's span.

      <IP_ADDRESS> The relative response factor (RRF) of the instrument calibration must be greater than 0.85 for all calibration check points (Eq. 9).

      <IP_ADDRESS> The mean percent difference between the known calibration gas value and the CEMS measured concentration at each of the three points (Eq.5) must be less than 5 percent of span.

0.3  Relative Accuracy Check  -  Reference Method

      <IP_ADDRESS> The  RA of the CEMS compared to a reference method in the units of the emission standard, must be less than or equal to 20 percent (Eq. 8) of the reference method when RMavgis used in the denominator of Eq. 8 or

      <IP_ADDRESS> In cases where the average emissions for the test are less than 50 percent of the applicable standard, substitute the emission standard value in the denominator of Eq. 8 in place of RMavg and the  RA must be less than or equal to 10 percent.

0.4 Accuracy Check - Dynamic Spiking

      <IP_ADDRESS>  The accuracy of the CEMS compared to a reference method in the units of the emission standard or to a dynamic spike, must be less than or equal to 20 percent when TMavg is used in the denominator of Eq. 8 or

1.0.1 In cases where the average emissions for the test are less than 50 percent of the applicable standard, you may substitute the emission standard value in the denominator of Eq. 8 in place of TMavg.  The accuracy must be less than or equal to 10 percent when the applicable emission standard is used in the denominator of Eq. 8.

SUPPLEMENTARY INFORMATION:

I. Statutory Background

    Under section 513 of the Federal Food, Drug, and Cosmetic Act (the
FD&C Act) (21 U.S.C. 360c), FDA must classify devices into one of three
regulatory classes: Class I, class II, or class III. FDA classification
of a device is determined by the amount of regulation necessary to
provide a reasonable assurance of safety and effectiveness. Under the
Medical Device Amendments of 1976 (1976 amendments) (Pub. L. 94-295),
as amended by the Safe Medical Devices Act of 1990 (Pub. L. 101-629),
devices are to be classified into class I (general controls) if there
is information showing that the general controls of the FD&C Act are
sufficient to assure safety and effectiveness; into class II (special
controls), if general controls, by themselves, are insufficient to
provide reasonable assurance of safety and effectiveness, but there is
sufficient information to establish special controls to provide such
assurance; and into class III (premarket approval), if there is
insufficient information to support classifying a device into class I
or class II and the device is a life-sustaining or life-supporting
device or is for a use which is of substantial importance in preventing
impairment of human health or presents a potential unreasonable risk of
illness or injury.
    Most generic types of devices that were on the market before the
date of the 1976 amendments (May 28, 1976) (generally referred to as
preamendments devices) have been classified by FDA under the procedures
set forth in section 513(c) and (d) of the FD&C Act through the
issuance of classification regulations into one of these three
regulatory classes. Devices introduced into interstate commerce for the
first time on or after May 28, 1976 (generally referred to as
postamendments devices), are classified through the premarket
notification process under section 510(k) of the FD&C Act (21 U.S.C.
360(k)). Section 510(k) of the FD&C Act and the implementing
regulations, 21 CFR part 807, require persons who intend to market a
new device to submit a premarket notification (510(k)) containing
information that allows FDA to determine whether the new device is
''substantially equivalent'' within the meaning of section 513(i) of
the FD&C Act to a legally marketed device that does not require
premarket approval.
    On November 21, 1997, the President signed into law FDAMA (Pub. L.
105-115). Section 206 of FDAMA, in part, added new section 510(m) to
the FD&C Act. Section 510(m)(1) of the FD&C Act requires FDA, within 60
days after enactment of FDAMA, to publish in the Federal Register a
list of each type of class II device that does not require a report
under section 510(k) of the FD&C Act to provide reasonable assurance of
safety and effectiveness. Section 510(m) of the FD&C Act further
provides that a 510(k) will no longer be required for these devices
upon the date of publication of the list in the Federal Register. FDA
published that list in the Federal Register of January 21, 1998 (63 FR
3142).

    Section 510(m)(2) of the FD&C Act provides that, 1 day after the
date of publication of the list under section 510(m)(1), FDA may exempt
a device on its own initiative or upon petition of an interested
person, if FDA determines that a 510(k) is not necessary to provide
reasonable assurance of the safety and effectiveness of the device.
This section, as amended by the 21st Century Cures Act (Pub. L. 114-
255), requires FDA to publish in the Federal Register a notice of
intent to exempt a device, or of the petition, and to provide a 60-day
comment period. Within 120 days of publication of this document, FDA
must publish in the Federal Register its final determination regarding
the exemption of the device that was the subject of the notice. If FDA
fails to respond to a petition under this section within 180 days of
receiving it, the petition shall be deemed granted.

II. Criteria for Exemption

    There are a number of factors FDA may consider to determine whether
a 510(k) is necessary to provide reasonable assurance of the safety and
effectiveness of a class II device. These factors are discussed in the
guidance the Agency issued on February 19, 1998, entitled ''Procedures
for Class II Device Exemptions from Premarket Notification, Guidance
for Industry and CDRH Staff.'' That guidance is available through the
internet at https://www.fda.gov/downloads/MedicalDevices/DeviceRegulationandGuidance/GuidanceDocuments/UCM080199.pdf or by
sending an email request to [email protected] to receive a copy
of the document. Please use the document number 159 to identify the
guidance you are requesting.

III. Proposed Class II Device Exemptions

    FDA has received the following petition requesting an exemption
from premarket notification for a class II device: Paul Hyman, Hyman,
Phelps & McNamara, PC, 700 13th St. NW., Suite 1200, Washington, DC
20005-5929, for OTC denture repair kits, classified under 21 CFR
872.3570.

IV. Paperwork Reduction Act of 1995

    This notice refers to previously approved collections of
information found in FDA regulations. These collections of information
are subject to review by the Office of Management and Budget (OMB)
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The
collections of information in 21 CFR 807, subpart E, regarding
premarket notification submissions, have been approved under OMB
control number 0910-0120.
