USEPAs Proposed Competency Requirements for
Performing Acid Rain, CAIR Mercury
RATAs(Includes Protocol Gas Verification Program
Presentation)
  • John Schakenbach, USEPA, CAMD
  • EPRI CEM Users Group Meeting
  • Phoenix, AZ
  • May 9 - 11, 2007

Background
  • 1970s stack test methods were developed
  • 1990s complaints on quality of stack testing
  • Dan Bivins worked on accrediting individuals and
    companies effort stalled
  • 1999 Dan restarted accreditation effort both SES
    and EPA wanted it NELAC wanted to be in charge
    of it
  • NELAC mainly involved in lab accreditation
  • Proposed a fee-based State-by-State program no
    individual qualification requirement

3
Background
  • 2001 Louisiana is only State with stack testing
    accreditation program
  • Currently no other States have plans to adopt
    NELAC approach
  • In 2001, to avoid State-by-State competency
    requirements and fees, ASTM got involved

4
Background
  • In 2004, ASTM D 7036-04 became final
  • Specifies general requirements for competence to
    perform air emissions tests of stationary sources
  • Consensus-based, developed by representatives
    from large and small stack testing companies,
    State and federal govs, private industry
  • Nationwide
  • Based largely on ISO 17025

5
Background
  • August 22, 2006 EPA proposed Part 75 rule
  • Any AETB conducting RATAs of CEMS or sorbent trap
    monitoring systems, or Appendix E testing, or
    deriving default emission rates for LME units
    under this part must conform to the requirements
    of ASTM D 7036-04
  • Not applicable to daily calibration error checks,
    daily flow interference checks, quarterly
    linearity checks or routine maintenance of CEMS
  • Comment period closed Oct 23, 2006

14
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment Will increase cost and difficulty.
  • Comment QSTI exams and accreditation are
    unavailable.
  • EPA Comment Accreditation is not required.
    STAC is providing accreditation if a company
    chooses to be accredited. SES is improving and
    expanding the QSTI examination process. If an
    external exam is not available, a company may
    provide internal exams.

15
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment Quality of data will not improve.
  • Comment Should exclude testing done by plant
    employees.
  • EPA Comment We are considering these and all
    other comments received.

16
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment How will compliance be determined?
  • EPA Comment
  • 6.1.2, Appendix A of the proposed Part 75 rule
    has two ways an AETB can certify compliance
  • A certificate of accreditation, or
  • A letter of certification signed by senior
    management
  • Every State has a field test observer program.
  • A standardized State observer checklist is being
    developed
  • EPA can use enforcement discretion.

17
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment What happens when test methods are
    created or revised?
  • EPA Comment
  • All Qualified Individuals must re-test every 5
    years.
  • If an external exam is unavailable, internal
    testing may be used to meet the requirements of
    D7036 until an external test is available.
  • 8.1, 8.2, 8.4, 12.6 and 12.9 of D7036 require
    an AETB to provide training to keep personnel
    up-to-date for any new or revised methods, and to
    evaluate the effectiveness of such training.

18
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment EPA should allow certification to other
    programs, e.g., Louisiana.
  • EPA Comment
  • LELAP was created before D7036 and was designed
    for Louisiana it is not a consensus standard.
  • Some stack test companies intend to comply with
    both D7036 and LELAP.
  • ASTM work group was trying to avoid
    State-by-State programs because companies would
    need to maintain and pay for the program in every
    State they do business.

19
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment One commenter suggested that the term
    documented quality system was unclear.
  • EPA Comment
  • The term is generally described in D7036,
    Sections 7.2.1, 7.2.2, and Note 7.
  • ANSI/ASQ E4-1994 defines a quality system as
  • a structured and documented system describing
    the policies, objectives, principles,
    organizational authority, responsibilities,
    accountability, and implementation plan of an
    organization for ensuring the quality in its work
    processes, products, items, and services. The
    quality system provides the framework for
    planning, implementing, and assessing work
    performed by the organization and for carrying
    out required QA and QC.

20
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment Several commenters suggested that a
    transition period should be provided before D7036
    is required.
  • EPA Comment
  • As of May 1, 2007, 54 QSTI (passed exam and
    experience requirements, and represent 34
    companies)
  • Group 1 43
  • (Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 2H, 3, 3B,
    4, 5, 5B, 5D, 5E, 5F 17)
  • Group 2 18
  • (3B, 6, 6A, 6B, 7, 7C, 8, 11, 13A, 15A, 16A, 26,
    26A, 202)
  • Group 3 34
  • (3A, 6C, 7E, 10, 10B, 20 25A, and PS2, PS3,
    PS4, PS4A, PS5, PS6 PS7)
  • Group 4 2
  • (12, 29, 101, 101A, 102 Ontario Hydro Method)

21
Summary of Significant Comments on Proposed Part
75 AETB Provision
  • Comment (Contd) Several commenters suggested
    that a transition period should be provided
    before D7036 is required.
  • EPA Comment (Contd)
  • SES is taking steps to improve and expand
    testing.
  • Many AETBs are going through STAC accreditation
    others will choose senior management
    certification.
  • If external exam not available, internal testing
    may be done until external exam is available.
  • We understand the need for a transition period,
    especially for the new mercury test methods which
    are not yet available.

24
USEPAs Proposed Protocol Gas Verification Program
25
What is the Problem?
  • Historically, blind audits of calibration gases
    have shown poor quality initially.
  • SO2 RATA using plants incorrect cal gas (low by
    15). Source could underreport SO2 by 15 and be
    undetected for at least 6 months.

26
Why is Accurate Cal Gas Important?
  • Only daily assurance CEM is really working
  • Reference Method analyzers need accurate
    calibration gases to produce accurate RATA
    results.

27
Purpose of Blind Audits
  • Help vendors improve gas quality
  • Help sources identify good vendors

28
Background
  • 1970s -1996, 2003, and 2006 EPA audited gases
  • Posted results (except for 2006)
  • In 1995, one vendor off by -16.3 (CEM would
    underreport)
  • Strong utility and vendor support
  • Auditing strongly correlated with improved gas
    quality

29
Audits Can Be Effective
1992 1993 1994 1995 1996 2003
30
Background
  • August 22, 2006 EPA proposed Part 75 rule
  • Any specialty gas company advertising,
    distributing, or certifying gas as EPA Protocol
    Gas must participate in the Protocol Gas
    Verification Program.
  • Comment period closed Oct 23, 2006

31
EPA Protocol Gas Verification Program
  • Created by EPA and specialty gas vendors
  • Funded by specialty gas vendors
  • Guided by an Advisory Group
  • EPA
  • Gas vendors
  • ICAC
  • EPRI
  • SES
  • NACAA (STAPPA/LAPCO)
  • Administered by ICAC

32
EPA Protocol Gas Verification Program
  • Institute of Clean Air Companies
  • Annually
  • Solicits gas producers to participate
  • Collects sufficient funds for program operation
    and disburses funds
  • Develops list of participants
  • Helps communicate results
  • Advisory Group
  • Negotiates contracts with third party sampling
    agent and lab and ICAC administrative costs
  • Sub group recommends gases to be audited

33
EPA Protocol Gas Verification Program
  • Third Party Sampling Agent
  • Obtains sample of unused, unexpired, EPA Protocol
    Gas cylinders sample is blind to gas producers
  • Ships cylinders to lab following chain of custody
    procedures
  • Third Party Analytical Verification Lab
  • Analyzes cylinders and reviews certificates of
    analysis
  • Reports results to EPA
  • Assists gas vendors upon request
  • Ships cylinders and certificates of analysis back
    to owner following chain of custody procedures

34
EPA Protocol Gas Verification Program
  • EPA
  • Provides overall technical oversight
  • Final selection of gases to be audited each year
  • Informs ICAC and gas vendors of audit results
  • Posts final audit results on web site
  • Specialty Gas Producers
  • Follow the EPA traceability protocol in making
    EPA Protocol Gas
  • Participate in and fund the PGVP if they
    advertise, distribute, or certify EPA Protocol
    Gas

35
Summary of Comments on Proposed Part 75 PGVP
Provision
  • Council of Industrial Boiler Owners was concerned
    about effects on gas supply and cost, and
    suggested at least a one year transition period
    before the PGVP takes effect.
  • One gas vendor submitted late comments against
    the program and several organizations submitted
    late supportive comments.

36
Next Steps
  • The proposed Part 75 rule is expected to become
    final late summer.
  • EPA will get the word out.
  • Once rule takes effect, utilities should
    remember
  • Anyone performing Part 75 RATAs, Appendix E or
    LME testing must comply with ASTM D 7036.
  • Any EPA Protocol Gases used must be from vendor
    participating in the PGVP.
