                                  1.0 Introduction
Background and Program Goals

The basic principles of the U.S. Environmental Protection Agency's (EPA) Traceability Protocol
for the Assay and Certification of Gaseous Calibration Standards (EPA, 1997)1 were developed
jointly by EPA, the National Bureau of Standards (now National Institute of Standards and
Technology [NIST]), and specialty gas producers over 30 years ago.  At the time, commercially-
prepared calibration gases were perceived as being too inaccurate and too unstable for use in
calibrations and audits of continuous source emission monitors and ambient air quality
monitors2. The protocol was developed to improve their quality by establishing their traceability
to NIST Standard Reference Materials (SRMs) and to provide reasonably priced products. This
protocol established the gas metrological procedures for measurement and certification of these
calibration gases for EPA's Acid Rain Program under 40 Code of Federal Regulations (CFR)
Part 75, for the Ambient Air Quality Monitoring Program under 40 CFR Part 58, and for the
Source Testing Program under 40 CFR Parts 60, 61, and 68. EPA required monitoring
organizations implementing these programs ("the regulated community") to use EPA Protocol
Gases as their calibration gases. EPA revised the protocol to establish detailed statistical
procedures for estimating the total uncertainty of these gases. EPA's Acid Rain Program
developed acceptance criteria for the uncertainty estimate3.

Specialty gas producers prepare and analyze EPA Protocol Gases without direct governmental
oversight.  In the 1980s and 1990s, EPA conducted a series of EPA-funded accuracy assessments
of EPA Protocol Gases sold by producers.  The intent of these audits was to:

    •   increase the acceptance and use of EPA Protocol Gases as calibration gases;
    •   provide a quality assurance (QA) check for the producers of these gases; and
    •   help users identify producers who can consistently provide accurately certified gases.

Either directly or through third parties, EPA procured EPA Protocol Gases from the producers,
assessed the accuracy of the gases' certified concentrations through independent analyses,  and
inspected the accompanying certificates of analysis for completeness and accuracy. The
producers were not aware that EPA had procured the gases for these audits.

The accuracy of the EPA Protocol Gases' certified concentrations was assessed using SRMs as
the analytical reference standards. If the difference between the audit's measured concentration
and the producer's certified concentration was more than +/- 2.0 percent or if the documentation
was incomplete or inaccurate, EPA notified the producer to resolve and correct the problem.

-------
The results of the accuracy assessments were published in peer-reviewed journals and were
posted on EPA's Technology Transfer Network website. The accuracy assessments were
discontinued in 1998.

In 2009, the Office of the Inspector General (OIG) published the report EPA Needs an Oversight
Program for Protocol Gases4.  One of the report's findings suggested that EPA "does not have
reasonable assurance that the gases that are used to calibrate emissions monitors for the Acid
Rain Program and continuous ambient monitors for the nation's air monitoring network are
accurate".  OIG recommended that OAR implement oversight programs to assure the quality of
the EPA Protocol Gases that are used to calibrate these monitors.  It also recommended that
EPA's ORD update and maintain the document Traceability Protocol for Assay and Certification
of Gaseous Calibration Standards to ensure that the monitoring programs' objectives are met.

In order to address the OIG findings for ambient air monitoring, OAQPS, in cooperation with
EPA Region 2 and 7 developed an Ambient Air Protocol Gas Verification Program (AA-PGVP).
The program establishes gas metrology laboratories in Regions 2 and 7 to verify the certified
concentrations of EPA Protocol Gases used to  calibrate ambient air quality monitors.   The
program is expected to ensure that producers selling EPA Protocol Gases participate in the AA-
PGVP, and provide end users with information about participating producers and verification
results.

The EPA Ambient Air Quality Monitoring Program's QA requirements 40 CFR Part 58,
Appendix A require:

    2.6 Gaseous and Flow Rate Audit Standards.  Gaseous pollutant concentration
    standards (permeation devices or cylinders of compressed gas) used to obtain test
    concentrations for CO, SO 2, NO, and NO 2 must be traceable to either a National
    Institute of Standards and Technology (NIST) Traceable Reference Material (NTRM),
    NIST Standard Reference Materials (SRM) and Netherlands Measurement Institute
    (NMi) Primary Reference Materials (valid as covered by Joint Declaration of
    Equivalence) or a NIST-certified Gas Manufacturer's Internal Standard (GMIS),
    certified in accordance with one of the procedures given in reference 4 of this appendix.
    Vendors advertising certification with the  procedures provided in reference 4 of this
    appendix and distributing gases as "EPA  Protocol Gas " must participate in the EPA
    Protocol Gas Verification Program or not use "EPA " in any form of advertising.

This program is considered a verification program because its current level of evaluation does
not allow for a large enough sample of EPA Protocol Gases from any one specialty gas  producer
to yield a statistically rigorous assessment of the accuracy of the producer's gases. It will not
provide end users with a scientifically defensible estimate of whether gases of acceptable quality
can be purchased from a specific producer.  Rather, the results provide information to end users
that the specialty gas producer is participating  in the program and with information that may be
helpful when selecting a producer.

                        2.0 Implementation Summary
Since program implementation started in 2010, when most of the initial preparation work took
place, there were no major "new" implementation activities in 2013. The following provides a
brief explanation of the 2013 implementation process.

Producer Information Data Collection - In 2010 EPA sent out an Excel spreadsheet to each
monitoring organization in order to obtain information on the gas standard producers being used
by the monitoring organization and to determine their interest in participating in the program. In
2011, EPA worked with Research Triangle Institute to develop a web-based survey that one
point of contact for each monitoring organization could access. This made recording and
evaluation of the survey information much easier for the monitoring organizations and EPA.
Based on the information obtained from monitoring organization surveys, EPA developed a list
of the specialty gas producers being used by the monitoring organizations. From this list, EPA
identified at least one point of contact for each producer. Most of the producers were the same as
listed the previous year but a few new producers were added.

AA-PGVP Verification Dates - OAQPS  worked with the Region 2 and 7 Regional Analytical
Verification Laboratories (RAVLs) to establish verification dates as indicated in Table 1.  The
dates were posted on the AMTIC website6. Monitoring organizations would contact the Regions
to schedule cylinder verifications.

RAVL Open House - Based on the information gained from monitoring organization surveys,
EPA contacted the producers by email to invite them to visit the RAVLs. The Region 2 open
house was December 3 - 5, 2013; the Region 7 open house was November 19-21, 2013.
Neither open house received any visitors for 2013.

1.  EPA sends emails to the monitoring organization's points of contact to complete the AA-
   PGVG Survey. EPA compiles information on specialty gas producers and the monitoring
   organizations that plan to participate. EPA tries to schedule the monitoring organization
   in an appropriate verification quarter based on delivery of standards from the specialty
   gas producer.
2.  The monitoring organizations order gas standards from specialty gas producers during the
   normal course of business. If EPA cannot get a cylinder from the monitoring
   organization, and that producer is being used, EPA will invite the producer to send a
   cylinder directly to an RAVL.
3.  The monitoring organizations send a new/unused standard,  specialty gas certification and
   chain of custody form to the RAVLs.
4.  The RAVLS analyze the cylinders and provide the validated results to OAQPS and the
   monitoring organizations.
5.  OAQPS reviews the data and  sends verification results to the specialty gas vendors.
6.  At the end of the year, OAQPS compiles final results into a report,  sends the report out to
   the specialty gas vendors and posts it on the AA-PGVP AMTIC web page.

                      3.0 Survey and Verification Results
Monitoring Organization Survey

Based upon the maximum capability of 40 gas cylinders per RAVL per year, the AA-PGVP
selection goal, in the following order, is:

    1)  One gas standard from every specialty gas producer being used by the monitoring
       community
    2)  Three standards per specialty gas producer
    3)  Weight additional standards by producer market share in ambient air monitoring
       community

In order to determine what specialty gas producers were being used by monitoring organizations,
EPA asked each monitoring organization to complete a web-based survey.  Unfortunately, due to
the transition from RTI as the support contractor to Battelle as the support contractor for the
program, in 2013, EPA received surveys from only 9 of a possible 120 monitoring organizations.
This low response was the result of training Battelle on the program, and transit!oning control of
the website over to them.  As a result, the majority of the cylinders submitted for verification in
2013 came from the gas producers.

Survey Results

Figure 2 identifies, as a percentage of the total responses,  how often the monitoring organizations
listed a particular specialty gas producer. As mentioned above, only 9 of the monitoring
organizations responded,  so this cannot be considered a complete survey.

Figure 2. Specialty Gas Producer Use
         PQAO/RO Specialty Gas Producer Use
                                        Six specialty gas producers were identified in the
                                        survey. However, some gas producers have more
                                        than one production facility and it is the intent of the
                                        AA-PGVP to try and receive one gas cylinder from
                                        every production facility being used by monitoring
                                        organizations (see Table 3).

                                        Participation in the AA-PGVP is voluntary. The
                                        survey asked whether a monitoring organization was
                                        receiving new gas standards during the year and,
also, whether they would like to participate by sending a cylinder to one of the RAVLs.  Of the 9
respondents, 5 sent cylinders to EPA. Table 2 lists the cylinders verified in CY2013. Some of
these cylinders contained multiple pollutants so, although 50 cylinders were sent to the RAVLs,
59 verifications were performed.

Specialty Gas Producers
EPA contacted all the specialty gas producers in the survey to:
                                  AA-PGVP 2013 Report 4/2014
                                               7

-------
   •   make them aware that EPA was starting the AA-PGVP,
   •   describe the details of the program and the website where they could find additional
       information,
   •   ask them to identify all of their production facilities so we could determine how to select
       cylinders from each production facility used, and
   •   make them aware that EPA would be scheduling an open house toward the end of the
       year.

Table 3 provides the information gathered in surveys from 2010 through 2013.  Since the
Emissions Monitoring Protocol Gas Verification Program7 and the AA-PGVP share the same
producer listing and coding scheme, Table 3 identifies the producers on both lists. The
producers shaded in green were identified on the AA-PGVP surveys.  The facilities shaded in
yellow were the facilities that the RAVLs received a cylinder for verification from monitoring
organization while those shaded in blue were provided directly from producers.  The facilities
shaded in red were identified on the monitoring organization surveys, but a standard from that
facility was not provided in the RAVLs in 2013. For 2013, of the six producers identified on the
surveys, only Norco was not verified. In addition, EPA performed verifications on five
producers that were not identified in the surveys as being  used in 2013.

                                AA-PGVP 2013 Report 4/2014

-------
Verification Results
As indicated in 40 CFR Part 75 Appendix A, EPA Protocol Gases must have a certified
uncertainty (95 percent confidence interval) that must not be greater than plus or minus (+) 2.0
percent of the certified concentration (tag value) of the gas mixture. This acceptance criterion is
for the Acid Rain Program. The AA-PGVP adopted the criteria as its data quality objective and
developed a quality system to allow the RAVLs to determine whether or not an individual
protocol gas standard concentration was within + 2% of the certified value. The Ambient Air
Program has never identified an acceptance criterion for the protocol gases.  Since the AA-PGVP
has not been established to provide a statistically rigorous assessment of any specialty gas
producer, the RAVLs report all valid results as analyzed but it is suggested that any difference
greater than 4-5% is cause for concern.  Information related to the analytical reference standards,
analytical instruments and methods used, the data reduction procedures and the data assessment
procedures are all found in the AA-PGVP QAPP and SOP and are not repeated in this report8.
Table 4 is the measurement quality objectives table that is included in the AA- PGVP QAPP
(Table 7-1 in QAPP).  The acceptance criteria  in Table 4 were met for each day of verification.
In addition, conformance to these requirements can be found in the measurement data
worksheets (MDW) that are generated for each comparison run and are available upon request.
Appendix A provides a report of the quality control  (QC) checks associated with each
verification run. Table 5 provides the verification results for CO and SO2, and Table 6 provides
the NOX results.

                                                     verified by both laboratories.  Region 7 did not
                                                     perform any NO/NOx verifications for AA-PGVP in
2013.  Although shown here, the QC cylinders were not part of the totals given in Table 2. The
internal QC results for CO and SO2 showed very good agreement, and all were well within the
2% RPD measurement quality objective.  As important as the agreement of the QC sample to the
certified concentration, equally important is the  comparability of the concentrations of the two
RAVLs. Table 7 provides the relative percent differences (di) of the paired QA sample
concentrations,  and is defined as:
                                                                 -•100
Where Xi = Region 2 RAVL concentration and
         Yt = Region 7 RAVL concentration

Selecting which lab was Xi and 7, was arbitrary.

Out of the 59 verification results,  only three were greater than the +2% Acid Rain Program
criteria and no value was greater than AA-PGVP 4-5% criteria.

Summary and Conclusions

In general, the AA-PGVP 2013 verifications were successful. The quality system, standard
operating procedures, analytical equipment and standards maintained the data quality of the
program. Results show that of the 59 verifications, 59 (100%) were within the + 4-5% AA-
PGVP criteria, and 56 (95%) were within the + 2% Acid Rain Program criteria.

The following lists some areas of the program that need improvement:

Survey Improvement - As mentioned earlier in the report, support contractor transition
significantly impacted survey completness in 2013. Now that the transition is completed, EPA
hopes to acheive 100% completeness on surveys in 2014. Repeated reminder email messages on
a two-week basis will be started once again and, if necessary, phone calls may be required to
meet the completeness goals.

Participation Improvement - Since the program is voluntary, EPA can not force participation.
Due to the budget/resource issues, many monitoring organization are more resource constrained
and, since the AA-PGVP is optional, it is treated as a lower priority. Since the only added
expense to monitoring organization is the shipping of cylinders to the RAVL, in 2014 will offer
monitoring organizations struggling with shipping costs a way to use EPA as a third-party payer.
This option will hopefully encourage greater participation from the various organizations.

Quarterly Intel-laboratory QC  Checks - The analysis of the same standard by both RAVLs
proved to be a useful tool for checking the quality of the AA-PGVP results. Up until now, the
RAVLS performed one check each.  Due to the interruption in 2013, the Regions were not able
to conduct the check in two quarters as previously planned.  Also, Region 7 is experiencing a
manpower issue, and may not be available for every quarter in 2014. Efforts will be made to
ensure their continued contribution to the program in the future.
