Amendments for Testing and Monitoring Provisions
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule: amendments.

-----------------------------------------------------------------------

SUMMARY: In this rule, we, the Environmental Protection Agency (EPA)  are making final minor amendments to our stationary source testing and  monitoring rules. These amendments include miscellaneous editorial  changes and technical corrections that are needed. We are also  promulgating Performance Specification 15, which contains the criteria  for certifying continuous emission monitoring systems (CEMS) that use  fourier transform infrared spectroscopy (FTIR). In addition, we are  changing the outline of the test methods and CEMS performance  specifications already listed in Parts 60, 61, and 63 to fit a new  format recommended by the Environmental Monitoring Management Council  (EMMC). The editorial changes and technical corrections update the  rules and help maintain their original intent. Performance  Specification 15 will provide the needed acceptance criteria for FTIR  CEMS as they emerge as a new technology. We are reformatting the test  methods and performance specifications to make them more uniform in  content and interchangeable with other Agency methods. The amendments  apply to a large number of industries that are already subject to the  current provisions of Parts 60, 61, and 63. Therefore, we have not  listed specific affected industries or their Standard Industrial  Classification codes here. 

DATES: Effective Date. This regulation is effective October 17, 2000. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of October 17, 2000.

 Why Were These Amendments Made?
         
     We have compiled miscellaneous errors and editions that are needed  for the test methods, performance specifications, and associated  regulations in 40 CFR Parts 60, 61, and 63. The corrections and  revisions consist primarily of typographical errors, technical errors  in equations and diagrams, and narrative that is no longer applicable  or is obsolete. Some of the revisions were brought to our attention by  the public. The major changes to the rule proposed on August 27, 1997  that resulted from public comments are discussed in Section III. Please  note that, although numerous technical corrections were made to Parts  60, 61, and 63 rules, none affected a compliance standard or reporting  or recordkeeping requirement. Revisions were only made to sections that  pertain to source testing or monitoring of emissions and operations.  

II. What Does the New EMMC Format for Methods Look Like?

    The new EMMC format we have adopted for analytical methods was  developed by consensus and will help integrate make consistent the test  methods written by different EPA programs. The test methods and  performance specifications being restructured in the new format are  shown in Table 1.

III. What Were the Significant Public Comments and What Resulting Changes Were Made Since Proposal?

    We asked that public comments on the August 27, 1997 proposal (62  FR 45369) be submitted by October 27, 1997. On November 18, 1997, we  reopened (62 FR 61483) the comment period to allow additional time for  review and comment. We received comments from facility owners and  operators, trade associations, State and Local air pollution control  agencies, environmental consultants, and private citizens. Their  comments were considered in developing this final action. A detailed  discussion of all comments are contained in the Summary of Comments and  Responses Document (see ADDRESSES section of this preamble). The major  public comments and the Agency's responses are summarized below. 

A. Update to ASTM Methods

    Several commenters supported our updating the references to ASTM  Standards to include the dates of the most recent versions. However,  some were concerned that updated standards not supplant the versions  previously allowed and those promulgated with the original regulation.  The ASTM recommended we follow the tradition of other governmental  agencies and list only the latest version of each standard. This would  present the latest, most improved standard. They felt that previously  approved versions would still be acceptable for future use, and this  could be noted in the preamble to the final rule.     

	On January 14, 1998, we published a supplementary Federal Register  notice to solicit public comments on this idea. We received three  comment letters. All commenters objected to the idea of listing only  the latest version of the ASTM standard. The commenters noted problems  that would be encountered with State Implementation Plans (SIP) wherein  only the specific ASTM standards listed in the subparts would be  allowed. They feared that listing only the latest version of the  standard would change the current allowance to use earlier versions.  This could potentially change the intent of the original emission  standard. Most commenters didn't think a preamble explanation was  sufficient assurance for continued allowance of earlier versions since  preambles are not published in the Code of Federal Regulations. There  were additional concerns for laboratories using currently acceptable  versions who would need to upgrade their practice to reflect the latest  version of a standard. The commenters were not amenable to only listing  the latest standard unless [[Page 61746]]language were added to the General Provisions of each part stating that  previously allowed versions of the standards were still allowed at the  discretion of the source. We feel the commenters have valid concerns  and have decided to continue the convention of listing all acceptable  versions of the ASTM standards including the new updates. The intent of  this action is to allow any of the yearly-designated versions of a  specific standard to be used in the applications where cited. 

B. Performance Requirements for Continuous Instrumental Methods of Part 
60--Methods 3A, 6C, 7E, 10, and 20

    Several commenters thought the preamble language for this proposal  gave inadequate notice of the changes being made. Commenters stated  that, in the proposal, we did not provide an adequate basis and purpose  statement and misled the readers into thinking that the proposal  contained no substantive changes to these test methods. Based on the  number of substantive changes in this proposal, and in light of the  Section 307(d) requirements, the commenters felt that we must address  these issues in a new proposal before the revisions can go final with  the rest of the package. We agree with the commenters that the preamble  to the proposed rule may not have given adequate public notice for some  of the revisions. The revisions to the continuous instrumental methods  (Methods 3A, 6C, 7E, 10, and 20) may be considered substantive, but  were not enumerated in the preamble nor was a supporting rationale  given. Therefore, the revisions to Methods 3A, 6C, 7E, 10, and 20 will  be reproposed as a separate rule. The comments already received on the  proposal of these methods will be held for consideration with any  future comments that result from the reproposal. 

C. Method 18 (Part 60, Appendix A)

    One commenter thought Method 18 was difficult to follow. The  commenter suggested that, to simplify organization of the method, we  should divide the method into five categories. Each title would begin  with ``Measurement of Gaseous Organic Compounds by Gas Chromatography''  but have the following subtitles: 
18A--Evacuated container sampling procedure.
18B--Bag sampling procedure.
18C--Direct interface procedure.
18D--Dilution interface procedure.
18E--Adsorption tube sampling procedure.

    Another commenter suggested dividing the method into two different  methods, one for the direct extractive technique, and the other for  sample collection into bags, flasks, or adsorbents.

    The method is currently divided according to the various sampling  procedures; for example, Section 8.2.2 is the Direct Interface Sampling  and Analysis Procedures, Section 8.2.3 is Dilution Interface Sampling  and Analysis Procedures, and so on. We do not believe that multiple  sampling procedures warrant dividing Method 18 into separate methods.  We feel a single method allowing different procedures offers the source  greater flexibility than citing specific procedures for particular  situations. One commenter noted that the proposed method requires  triplicate injections for analysis of the calibration standards used  for preparing the pre-test calibration curve, triplicate injections of  the test samples, and triplicate injections for construction of the  post-test calibration curve. The commenter questioned the additional  accuracy expected for the extra hours spent in sample analysis and  calibration while in the field conducting a source test compared to the  current method which requires two consecutive analyses for pre- and  post-test calibration and sample analyses meeting the same criteria for  acceptance. We are increasing the calibration requirement to triple  injections to tighten the method's quality assurance procedures.  Triplicate calibration injections is the normal procedure prevalent in  the analytical community, as well as in other Agency methodologies. It  is difficult to establish precision and accuracy with duplicate  injections. However, triplicate injections provide a reasonable measure  of analytical precision without being overly burdensome. We do not feel  the increase in time and costs associated with the third injection will  significantly affect a typical test, considering the added benefits to  data quality that are gained.

    Several commenters asked us to revise and clarify various aspects of Section 10. We have made these modifications to address their concerns.

    Regarding Section 13.1, one commenter noted that Method 18 is not a method in the general sense, but is more of a guideline on how to develop and document a test method. The commenter therefore felt that  any prospective method should be written up and submitted to us along  with the proper documentation that includes recovery study results. We  disagree with this commenter. Method 18, which has been cited and used  for many years, is a specific gas chromatography method with specific  sampling, analytical, and data quality requirements. The method was  written to accommodate many test sites having many possible target  compounds and gas matrices. The tester has been given numerous  sampling, separation, and analytical system options to make the method  adaptable to the needs of various compliance demonstrations.

     Several commenters asked us to clarify the 5 to 10 percent relative standard deviation (RSD) requirement for calibration standards in Section 13.1.

    We have added clarity to Section 13.1. The 5 to 10 percent RSD is not a precision criterion for calibration standards but a typical precision range for analyzing field samples. Five percent RSD is required for triplicate injections of calibration standards.

D. Method 25 (Part 60, Appendix A)

    One commenter noted that Method 25 has limitations due to  conditions that may exist in stack gas. If such conditions exist, the  commenter recommends interfacing a nonmethane analyzer directly to the  source or use Method 25A or 25B to measure the emissions. The commenter  recommended modifying Method 25 to allow instruments that are able to  determine the methane and nonmethane portions using components  different from those described by Method 25 when the analyzer is  directly interfaced to the source. The commenter feels that Method 25  would be more practical for determining methane/nonmethane emissions at  the field site if the method could be modified to allow these other  analyzers. The commenter feels that it will also be necessary that  fixed performance specifications be defined in the method, such as  those for Method 6C. We believe these comments address method changes  that are beyond those covered in the proposal and are, therefore,  beyond the scope of this action. The commenter is encouraged to pursue  these method changes through other appropriate channels such as  submitting a request to use them as an alternative method. 

E. Performance Specification 15 (Part 60, Appendix B)

    One commenter noted that the statement of applicability for the  demonstration is limited to the criteria we gave. The commenter stated  that, with performance based measurement systems, the focus is on data  quality objectives (DQO) where the performance specifications are  coupled with the DQO. We believe the purpose of reference methods and,  in this case  [[Page 61747]]  performance specifications, is to provide standard procedures for  sources to follow in order to provide quality emission data. However,  we do provide latitude to sources by publishing performance-based  methods and PS whenever possible. This performance specification is one  such procedure; as long as an FTIR sampling system meets the  requirements of the performance specifications, it can be used for any  regulated pollutant.

     Based on public comments and upon further deliberation, we have  removed the system calibration requirement from Section 10.3 of PS-15.  Since both a system calibration and the calibration transfer standard  measurement basically test instrument function, having both of these  requirements in the performance specifications is redundant.

    One commenter felt that the number of runs should be given as  ``guidance'' rather than made a requirement. We set the requirement for  nine runs (when comparing the FTIR to a reference method) and 10 runs  (when comparing the FTIR to a reference monitor) because these are standard procedures for performance specifications. We note that this  performance specification also allows analyte spiking as an option;  therefore, a revision on this point is not necessary.

    One commenter noted that Section 11.1.1.4.3 states ``if the RM is a CEM, synchronize the sampling flow rates of the RM and the FTIR CEM.'' The commenter noted that instrumental analyzers are currently used for reference methods. EPA Methods 6C, 7E, 3A, and 10 measure SO2, NOX, O2, CO2, and CO on a continuous basis for a short period of time and are referred to as instrumental analyzers and not CEMs. The commenter felt the statement should read ``if the reference method is an instrumental analyzer, synchronize the sampling flow rates of the RM and the FTIR.'' We agree with the commenter and have made the noted change.

IV. What Revisions Were Made That Were Not in the Proposed Rule?

    A revision was made to Section 6.6 of Method 21 of Part 60 to  clarify the VOC monitoring instrument specifications. The requirement  for the instrument to be intrinsically safe for Classes 1 and 2,  Division 1 conditions has been amended to require them to be  intrinsically safe for Class 1 and/or Class 2, Division 1 conditions,  as appropriate. The performance test provisions of Sec. 60.754(d) for  determining control device efficiency when combusting landfill gas were  amended to allow the use of Method 25 as an alternative to Methods 18  and 25C. The tester has the option of using either Method 18, 25, or  25C in this case. These amendments were not published in the proposed  rule.
