In accordance with the National Environmental Policy Act of 1969, as amended, and Federal Energy Regulatory Commission (Commission or FERC) regulations (18 CFR Part 380), Commission staff reviewed the application for a minor license for the Santa Felicia Hydroelectric Project and prepared this final environmental assessment (EA). The project is located on Piru Creek in Ventura County, California. The project occupies 174.5 acres of U.S. land that is administered by the U.S. Department of Agriculture, Forest Service (Forest Service) in the Los Padres and Angeles National Forests. Specifically, the project licensee, United Water Conservation District, requested Commission approval of the Santa Felicia Project for hydroelectric generation purposes. In the final EA, Commission staff analyze the probable environmental effects of relicensing the project and conclude that approval of the project, with appropriate staffrecommended environmental measures, would not constitute a major federal action significantly affecting the quality of the human environment. Copies of the final EA are available for review in Public Reference Room 2–A of the Commission’s offices at 888 First Street, NE., Washington, DC. The EA also may be viewed on the Commission’s Internet Web site (www.ferc.gov) using the ‘‘eLibrary’’ link. Additional information about the project is available from the Commission’s Office of External Affairs at (202) 502–6088, or on the Commission’s Web site using the eLibrary link.

The Federal Energy Regulatory Commission’s Office of Energy Projects has updated its prior guidelines and is making available for public comment a document entitled ‘‘Seismic Design Guidelines and Data Submittal Requirements for LNG Facilities’’. These draft guidelines apply to all proposed new LNG facilities and proposed significant changes to existing LNG facilities under the jurisdiction of the Federal Energy Regulatory Commission. The new guidelines update, replace and supersede ‘‘Data Requirements for the Seismic Review of LNG Facilities, NBSIR 84–2833’’ (18 CFR 380.12(h)(5) and (o)(15)). Federal regulations applicable to seismic design of LNG facilities are identified and summarized, and guidance is provided in a number of areas that may be subject to interpretation by technical experts. The guidelines provide a basis for uniform reviews of various LNG terminal structures, components and systems under FERC jurisdiction. This guidance is intended for those facilities to be constructed on land and is not intended for floating or offshore facilities. The scope of the guidelines includes all portions of the facility located within the facility security fence including loading docks. The document may be downloaded from the FERC Web site at: https:// www.ferc.gov/industries/lng.asp. A limited number of paper copies are available from the Commission’s Public Reference Room, or by contacting the FERC Project Manager identified below.

ACTION: Notice of availability. AGENCY: SUMMARY: This notice announces broadly applicable alternative test method approval decisions that the Environmental Protection Agency has made under and in support of the New Source Performance Standards and the National Emission Standards for Hazardous Air Pollutants. Although we have made both site-specific and broadly applicable alternative test method approvals in the past, most recently we have issued only site- or facility-specific approvals. This notice announces our plan to issue broadly applicable alternative test method approvals in the future. We will post these broadly applicable approvals on our technology transfer network Web site as well as announce them in the Federal Register. The publication of these broadly applicable alternative test method approvals on our Web site will provide information about options and flexibility for the regulated community. In addition, this information may reduce the burden on source owners and operators in making site-specific alternative test method requests and the permitting authorities and the EPA E:\FR\FM\30JAN1.SGM 30JAN1 4258 Federal Register / Vol. 72, No. 19 / Tuesday, January 30, 2007 / Notices I.

Does this action apply to me? This announcement will be of interest to entities regulated under 40 CFR parts 60, 61, and 63 and State, local, Tribal agencies, and EPA Regional Offices responsible for implementation and enforcement of regulations under 40 CFR parts 60, 61, and 63. B. How can I get copies of this information? You may access copies of the broadly applicable alternative test method approvals from the EPA’s Web site at https://www.epa.gov/ttn/emc/ tmethods.html#CatB. II. Background Broadly applicable alternative test method approval decisions that we have made in the past under the New Source Performance Standards (NSPS), 40 CFR part 60 and the National Emission Standards for Hazardous Air Pollutants (NESHAP), 40 CFR parts 61 and 63 are identified in this notice (see Table 1). Most of our prior alternative test method approvals have been on a facilityspecific basis, but we plan to issue more broad (i.e., source category-wide) alternative test method approvals in the future, and we will post these broadly applicable approvals on our technology transfer network Web site. We will also announce them in the Federal Register. Source owners or operators may voluntarily choose to use these broadly applicable alternative test methods. Use of these alternatives does not change the applicable emission standards.

Method 2, Determination of Stack Gas Sources required to use Method 2 Velocity and Volumetric Flow Rate under 40 CFR parts 60, 61, or 63. (Type S Pitot Tube). Alternative test methods and procedures are necessary for various reasons. In some cases, there are inherent restrictions in test methods which warrant a deviation from a specific requirement in the method. For example, the sampling equipment specified in Method 5 is not appropriate at stack temperatures greater than 1200 degrees Fahrenheit, and in such cases, water-cooled probes are necessary. As another example, it is problematic to measure volatile organic compounds (VOCs) at concentrations below 50 parts per million (ppm) using Method 25 (40 CFR part 60, appendix A), so other methods (notably Method 25A) have been approved for this situation. Also, new and improved testing techniques are developed over time. As pollution controls improve and emissions decrease, it may be necessary or desirable to utilize newer methods with advantages such as lower detection limits. The EPA Administrator has the authority to approve the use of alternative test methods to comply with requirements under 40 CFR parts 60, 61, and 63. This authority is found in §§ 60.8(b)(3), 61.13(h)(1)(ii), and 63.7(e)(2)(ii). In 40 CFR part 63, § 63.2, VerDate Aug<31>2005 For . . . 15:36 Jan 29, 2007 Jkt 211001 test method is defined as ‘‘the validated procedure for sampling, preparing, and analyzing for an air pollutant specified in a relevant standard as the performance test procedure. The test method may include methods described in an appendix of this chapter, test methods incorporated by reference in this part, or methods validated for an application through procedures in Method 301 of appendix A of this part.’’ The term ‘‘reference method’’ is used in 40 CFR parts 60 and 61 instead of the term ‘‘test method.’’ In 40 CFR part 60, reference method means ‘‘any method of sampling and analyzing for an air pollutant as specified in the applicable subpart.’’ The definition in 40 CFR part 61 is similar. For simplicity, we use the term ‘‘test method’’ in this notice to refer to both ‘‘test methods’’ under 40 CFR part 63 and ‘‘reference methods’’ under 40 CFR parts 60 and 61. Citations and definitions in all three of these parts refer to the use of alternatives to test (or reference) methods. Under 40 CFR part 60, alternative method means ‘‘any method of sampling and analyzing for an air pollutant which is not a reference or equivalent method but which has been demonstrated to the EPA Administrator’s satisfaction to, in PO 00000 Frm 00030 Fmt 4703 Sfmt 4703 Use Method 316 to measure formaldehyde emissions in lieu of Method 18. Use CARB Method 431 in lieu of procedures (including Method 18) in 40 CFR § 63.365. Use NCASI Chilled Water/Impinger/ Silica Gel Tube Test Method in lieu of Method 308 Use SCAQMD Method 205.1 in lieu of Method 306. Use Method 2G (three-dimensional probe), Method 2F (two-dimensional probe), or Method 2H (taking into account velocity decay near stack wall) in lieu of Method 2, as appropriate. specific cases, produce results adequate for his determination of compliance.’’ Again, 40 CFR part 61 contains a similar definition. 40 CFR part 63 defines alternative test method as ‘‘any method of sampling and analyzing for an air pollutant that is not a test method in this chapter and that has been demonstrated to the EPA Administrator’s satisfaction, using Method 301 in appendix A of this part, to produce results adequate for the EPA Administrator’s determination that it may be used in place of a test method specified in this part.’’ Over the years, we have performed thorough technical reviews of numerous requests for alternatives and modifications to test methods and procedures. Based on these experiences, we have found that often, these changes or alternatives would be equally valid and appropriate to apply to other sources within a particular class, category, or subcategory. Consequently, we have concluded that where a method modification or a change or alternative is clearly broadly applicable to a class, category, or subcategory of sources, it is both more equitable and efficient to approve its use for all appropriate sources and situations at the same time. E:\FR\FM\30JAN1.SGM 30JAN1 ycherry on PROD1PC64 with NOTICES Federal Register / Vol. 72, No. 19 / Tuesday, January 30, 2007 / Notices This approach would not change the practical outcome of whether any specific request would or would not be approved. However, approving broadly applicable alternative test methods would expedite the approval process, provide additional flexibility for the regulated community, and reduce the burden on source owners and operators, the permitting authorities, and the EPA Administrator. Where technically appropriate, we will continue, as always, to approve the use of an alternative test method or modification to a test method for a specific source only. It is important to clarify that alternative methods are not mandatory but permissible. That is, no source is required to employ such a method but may choose to do so in appropriate cases. By electing to use an alternative method, the source owner or operator consents to thereafter demonstrating compliance with applicable requirements based on the results of the alternative method until approved to do otherwise. If you are aware of reasons why a particular alternative test method approval that we issue should not be broadly applicable, we request that you make us aware of the reasons within 60 days of the Federal Register notice announcing the broad approval, and we will revisit the broad approval. Approvals for broadly applicable alternative test methods will be announced on our technology transfer network Web site https://www.epa.gov/ ttn/emc/tmethods.html#CatB soon after they are issued, as well as through periodic notices of this kind. Likewise, any objection to a broadly applicable alternative test method as well as the resolution to that objection will be posted on the same Web site and announced in the subsequent Federal Register notice. If we should decide to retract a broadly applicable alternative test method, we would continue to grant case-by-case approvals, as appropriate, and would (and States should) consider the need for an appropriate transition period for users either to request caseby-case approval or to transition to an approved method. Section 63.90(a) of 40 CFR part 63 defines three categories of alternatives or changes to test methods: minor changes, intermediate changes, and major changes. A major change to a test method includes modifications using ‘‘unproven technology or procedures’’ (those not generally accepted by the scientific community), entirely new methods, or changes that apply to a category or subcategory of affected sources. Such changes will almost always set a national precedent. Under VerDate Aug<31>2005 15:36 Jan 29, 2007 Jkt 211001 40 CFR part 63, § 63.91(g), a State may ask EPA to delegate the authority to approve minor and intermediate, but not major alternatives to test methods. The Agency’s policy has been to retain the authority to approve major changes to test methods at the national level to assure uniformity and technical quality in the test methods used for enforcement of national standards. Likewise, broad approvals to alternative test methods would be made only at the national level or as part of a revision to a State or Tribal implementation plan. A. Criteria for Approval of Alternative Methods The definitions of ‘‘alternative method’’ in 40 CFR parts 60 and 61 and ‘‘alternative test method’’ in 40 CFR part 63, establish the principal criterion for approval of an alternative test method: The EPA Administrator or his authorized representative must be satisfied that the test method alternative will produce results adequate to determine compliance. In other words, the EPA Administrator or authorized representative, such as a State having delegated authority, generally must be assured that a test method change provides a determination of compliance status at the same or greater stringency as the test method specified in the applicable regulation. The General Provisions to 40 CFR part 63 provide a number of specifications regarding the content and process for alternative test method requests. In particular, § 63.7(f)(2)(i) stipulates that the source owner or operator must notify the EPA Administrator of the intent to use an alternative test method at least 60 days before the performance test is scheduled. Section 63.7(f)(2) clarifies that a written application is required for approval of an alternative test method and specifies that the submittal to the EPA Administrator must include the results of the Method 301 validation process as well as justification for not using the test method specified in the applicable subpart. The 40 CFR parts 60 and 61 General Provisions are less specific. Nevertheless, based on our experience in responding to hundreds of alternative test method requests over the last 30 years, we ask that alternative test method requests include the applicable Federal regulation and test method, a description of the process and controls to which the alternative method will be applied, a description of the alternative testing procedures as well as the justification for use of the alternative and Method 301 validation data required under 40 CFR part 63. PO 00000 Frm 00031 Fmt 4703 Sfmt 4703 4261 B. Procedures for Submission and Review of Alternative Methods Considering that the different levels of alternatives or changes to test methods (minor, intermediate, and major) may be acted on by differing levels of government (e.g., State, local, and Tribal agencies; EPA Regional Offices; or EPA Headquarters), we recommend that the owner/operator of an affected source consult with the responsible agency to determine how and to whom a request for a particular request for an alternative method should be submitted. Review processes may vary depending on the agency involved. The process described here is typical of how EPA Headquarters might handle a request for an alternative test method. Upon our receipt of a written request, the request is recorded in our tracking system. Within a few days of receipt of the request, a technical expert determines whether or not the request is complete (i.e., contains sufficient supporting data and information). The technical expert then acknowledges receipt of the request and notifies the requester that we are evaluating the request. The reviewer evaluates the request and supporting information to confirm that the proposed alternative is justified, technically sound, and that it will produce results adequate to determine compliance with the emission standards. The reviewer analyzes all necessary information to check the accuracy and repeatability of the alternative method. As previously noted, § 63.7(f)(2)(iii) of 40 CFR part 63 specifies that the results of a Method 301 validation and justification for not using the specified method must accompany a request for approval to use an alternative test method. Method 301, Validation of Pollutant Measurement Methods from Various Waste Media includes procedures for determining and documenting the systematic error (i.e., bias) and random error (i.e., precision) of a measurement system. The procedures involve introducing known concentrations of an analyte or comparing the test method against a validated test method to determine the method’s bias and collecting multiple or co-located simultaneous samples to determine the method’s precision. Method 301 validation testing or data in a form responsive to § 12 of Method 301 should also accompany requests for major changes to test methods under parts 60 and 61. During the review process, all relevant documents (emails, letters, and other supporting materials) are retained and filed. Once the review process has been completed, we issue an official letter providing E:\FR\FM\30JAN1.SGM 30JAN1 4262 Federal Register / Vol. 72, No. 19 / Tuesday, January 30, 2007 / Notices written notification of approval/ disapproval of the alternative test method request under § 63.7(f)(3), § 60.8(b), or § 61.13(h)(1). C. Recording and Publication As noted earlier, approvals for broadly applicable alternative test methods will be announced on the EPA’s Web site at https://www.epa.gov/ ttn/emc/tmethods.html#CatB as soon as they are issued. The notification on our Technology Transfer Network (TTN) Web site will clearly indicate each class, category, or subcategory of sources for which the change or alternative test method is approved. We intend to publish a notice annually that summarizes approvals for broadly applicable alternative test methods. Table 1 in this notice includes a summary of broad approvals that have been posted to the TTN. Complete copies of these documents may be obtained at https://www.epa.gov/ttn/ emc/tmethods.html#CatB.

[FRL-8273-6]


Notice of Broadly Applicable Alternative Test Methods

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

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

SUMMARY: This notice announces broadly applicable alternative test 
method approval decisions that the Environmental Protection Agency has 
made under and in support of the New Source Performance Standards and 
the National Emission Standards for Hazardous Air Pollutants. Although 
we have made both site-specific and broadly applicable alternative test 
method approvals in the past, most recently we have issued only site- 
or facility-specific approvals. This notice announces our plan to issue 
broadly applicable alternative test method approvals in the future. We 
will post these broadly applicable approvals on our technology transfer 
network Web site as well as announce them in the Federal Register. The 
publication of these broadly applicable alternative test method 
approvals on our Web site will provide information about options and 
flexibility for the regulated community. In addition, this information 
may reduce the burden on source owners and operators in making site-
specific alternative test method requests and the permitting 
authorities and the EPA

[[Page 4258]]

Administrator in processing those requests.

FOR FURTHER INFORMATION CONTACT: Broadly applicable alternative test 
method approvals may be accessed from the EPA's Web site at https://
www.epa.gov/ttn/emc/tmethods.html#CatB. For questions about this 
notice, contact Robin R. Segall, Air Quality Assessment Division, 
Office of Air Quality Planning and Standards (E143-02), Environmental 
Protection Agency, Research Triangle Park, NC 27711; telephone number 
(919) 541-0893; fax number (919) 541-0893; e-mail address: 
segall.robin@epa.gov. For technical questions about individual 
alternative test method decisions, refer to the contact person 
identified in the individual approval documents.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    This announcement will be of interest to entities regulated under 
40 CFR parts 60, 61, and 63 and State, local, Tribal agencies, and EPA 
Regional Offices responsible for implementation and enforcement of 
regulations under 40 CFR parts 60, 61, and 63.

B. How can I get copies of this information?

    You may access copies of the broadly applicable alternative test 
method approvals from the EPA's Web site at https://www.epa.gov/ttn/emc/
tmethods.html#CatB.

II. Background

    Broadly applicable alternative test method approval decisions that 
we have made in the past under the New Source Performance Standards 
(NSPS), 40 CFR part 60 and the National Emission Standards for 
Hazardous Air Pollutants (NESHAP), 40 CFR parts 61 and 63 are 
identified in this notice (see Table 1). Most of our prior alternative 
test method approvals have been on a facility-specific basis, but we 
plan to issue more broad (i.e., source category-wide) alternative test 
method approvals in the future, and we will post these broadly 
applicable approvals on our technology transfer network Web site. We 
will also announce them in the Federal Register. Source owners or 
operators may voluntarily choose to use these broadly applicable 
alternative test methods. Use of these alternatives does not change the 
applicable emission standards.

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

    Alternative test methods and procedures are necessary for various 
reasons. In some cases, there are inherent restrictions in test methods 
which warrant a deviation from a specific requirement in the method. 
For example, the sampling equipment specified in Method 5 is not 
appropriate at stack temperatures greater than 1200 degrees Fahrenheit, 
and in such cases, water-cooled probes are necessary. As another 
example, it is problematic to measure volatile organic compounds (VOCs) 
at concentrations below 50 parts per million (ppm) using Method 25 (40 
CFR part 60, appendix A), so other methods (notably Method 25A) have 
been approved for this situation. Also, new and improved testing 
techniques are developed over time. As pollution controls improve and 
emissions decrease, it may be necessary or desirable to utilize newer 
methods with advantages such as lower detection limits.
    The EPA Administrator has the authority to approve the use of 
alternative test methods to comply with requirements under 40 CFR parts 
60, 61, and 63. This authority is found in Sec. Sec.  60.8(b)(3), 
61.13(h)(1)(ii), and 63.7(e)(2)(ii). In 40 CFR part 63, Sec.  63.2, 
test method is defined as ``the validated procedure for sampling, 
preparing, and analyzing for an air pollutant specified in a relevant 
standard as the performance test procedure. The test method may include 
methods described in an appendix of this chapter, test methods 
incorporated by reference in this part, or methods validated for an 
application through procedures in Method 301 of appendix A of this 
part.'' The term ``reference method'' is used in 40 CFR parts 60 and 61 
instead of the term ``test method.'' In 40 CFR part 60, reference 
method means ``any method of sampling and analyzing for an air 
pollutant as specified in the applicable subpart.'' The definition in 
40 CFR part 61 is similar. For simplicity, we use the term ``test 
method'' in this notice to refer to both ``test methods'' under 40 CFR 
part 63 and ``reference methods'' under 40 CFR parts 60 and 61. 
Citations and definitions in all three of these parts refer to the use 
of alternatives to test (or reference) methods. Under 40 CFR part 60, 
alternative method means ``any method of sampling and analyzing for an 
air pollutant which is not a reference or equivalent method but which 
has been demonstrated to the EPA Administrator's satisfaction to, in 
specific cases, produce results adequate for his determination of 
compliance.'' Again, 40 CFR part 61 contains a similar definition. 40 
CFR part 63 defines alternative test method as ``any method of sampling 
and analyzing for an air pollutant that is not a test method in this 
chapter and that has been demonstrated to the EPA Administrator's 
satisfaction, using Method 301 in appendix A of this part, to produce 
results adequate for the EPA Administrator's determination that it may 
be used in place of a test method specified in this part.''
    Over the years, we have performed thorough technical reviews of 
numerous requests for alternatives and modifications to test methods 
and procedures. Based on these experiences, we have found that often, 
these changes or alternatives would be equally valid and appropriate to 
apply to other sources within a particular class, category, or 
subcategory. Consequently, we have concluded that where a method 
modification or a change or alternative is clearly broadly applicable 
to a class, category, or subcategory of sources, it is both more 
equitable and efficient to approve its use for all appropriate sources 
and situations at the same time.

[[Page 4261]]

This approach would not change the practical outcome of whether any 
specific request would or would not be approved. However, approving 
broadly applicable alternative test methods would expedite the approval 
process, provide additional flexibility for the regulated community, 
and reduce the burden on source owners and operators, the permitting 
authorities, and the EPA Administrator. Where technically appropriate, 
we will continue, as always, to approve the use of an alternative test 
method or modification to a test method for a specific source only. It 
is important to clarify that alternative methods are not mandatory but 
permissible. That is, no source is required to employ such a method but 
may choose to do so in appropriate cases. By electing to use an 
alternative method, the source owner or operator consents to thereafter 
demonstrating compliance with applicable requirements based on the 
results of the alternative method until approved to do otherwise.
    If you are aware of reasons why a particular alternative test 
method approval that we issue should not be broadly applicable, we 
request that you make us aware of the reasons within 60 days of the 
Federal Register notice announcing the broad approval, and we will 
revisit the broad approval. Approvals for broadly applicable 
alternative test methods will be announced on our technology transfer 
network Web site https://www.epa.gov/ttn/emc/tmethods.html#CatB soon 
after they are issued, as well as through periodic notices of this 
kind. Likewise, any objection to a broadly applicable alternative test 
method as well as the resolution to that objection will be posted on 
the same Web site and announced in the subsequent Federal Register 
notice. If we should decide to retract a broadly applicable alternative 
test method, we would continue to grant case-by-case approvals, as 
appropriate, and would (and States should) consider the need for an 
appropriate transition period for users either to request case-by-case 
approval or to transition to an approved method.
    Section 63.90(a) of 40 CFR part 63 defines three categories of 
alternatives or changes to test methods: minor changes, intermediate 
changes, and major changes. A major change to a test method includes 
modifications using ``unproven technology or procedures'' (those not 
generally accepted by the scientific community), entirely new methods, 
or changes that apply to a category or subcategory of affected sources. 
Such changes will almost always set a national precedent. Under 40 CFR 
part 63, Sec.  63.91(g), a State may ask EPA to delegate the authority 
to approve minor and intermediate, but not major alternatives to test 
methods. The Agency's policy has been to retain the authority to 
approve major changes to test methods at the national level to assure 
uniformity and technical quality in the test methods used for 
enforcement of national standards. Likewise, broad approvals to 
alternative test methods would be made only at the national level or as 
part of a revision to a State or Tribal implementation plan.

A. Criteria for Approval of Alternative Methods

    The definitions of ``alternative method'' in 40 CFR parts 60 and 61 
and ``alternative test method'' in 40 CFR part 63, establish the 
principal criterion for approval of an alternative test method: The EPA 
Administrator or his authorized representative must be satisfied that 
the test method alternative will produce results adequate to determine 
compliance. In other words, the EPA Administrator or authorized 
representative, such as a State having delegated authority, generally 
must be assured that a test method change provides a determination of 
compliance status at the same or greater stringency as the test method 
specified in the applicable regulation.
    The General Provisions to 40 CFR part 63 provide a number of 
specifications regarding the content and process for alternative test 
method requests. In particular, Sec.  63.7(f)(2)(i) stipulates that the 
source owner or operator must notify the EPA Administrator of the 
intent to use an alternative test method at least 60 days before the 
performance test is scheduled. Section 63.7(f)(2) clarifies that a 
written application is required for approval of an alternative test 
method and specifies that the submittal to the EPA Administrator must 
include the results of the Method 301 validation process as well as 
justification for not using the test method specified in the applicable 
subpart. The 40 CFR parts 60 and 61 General Provisions are less 
specific. Nevertheless, based on our experience in responding to 
hundreds of alternative test method requests over the last 30 years, we 
ask that alternative test method requests include the applicable 
Federal regulation and test method, a description of the process and 
controls to which the alternative method will be applied, a description 
of the alternative testing procedures as well as the justification for 
use of the alternative and Method 301 validation data required under 40 
CFR part 63.

B. Procedures for Submission and Review of Alternative Methods

    Considering that the different levels of alternatives or changes to 
test methods (minor, intermediate, and major) may be acted on by 
differing levels of government (e.g., State, local, and Tribal 
agencies; EPA Regional Offices; or EPA Headquarters), we recommend that 
the owner/operator of an affected source consult with the responsible 
agency to determine how and to whom a request for a particular request 
for an alternative method should be submitted. Review processes may 
vary depending on the agency involved. The process described here is 
typical of how EPA Headquarters might handle a request for an 
alternative test method. Upon our receipt of a written request, the 
request is recorded in our tracking system. Within a few days of 
receipt of the request, a technical expert determines whether or not 
the request is complete (i.e., contains sufficient supporting data and 
information). The technical expert then acknowledges receipt of the 
request and notifies the requester that we are evaluating the request. 
The reviewer evaluates the request and supporting information to 
confirm that the proposed alternative is justified, technically sound, 
and that it will produce results adequate to determine compliance with 
the emission standards. The reviewer analyzes all necessary information 
to check the accuracy and repeatability of the alternative method. As 
previously noted, Sec.  63.7(f)(2)(iii) of 40 CFR part 63 specifies 
that the results of a Method 301 validation and justification for not 
using the specified method must accompany a request for approval to use 
an alternative test method. Method 301, Validation of Pollutant 
Measurement Methods from Various Waste Media includes procedures for 
determining and documenting the systematic error (i.e., bias) and 
random error (i.e., precision) of a measurement system. The procedures 
involve introducing known concentrations of an analyte or comparing the 
test method against a validated test method to determine the method's 
bias and collecting multiple or co-located simultaneous samples to 
determine the method's precision. Method 301 validation testing or data 
in a form responsive to Sec.  12 of Method 301 should also accompany 
requests for major changes to test methods under parts 60 and 61. 
During the review process, all relevant documents (e-mails, letters, 
and other supporting materials) are retained and filed. Once the review 
process has been completed, we issue an official letter providing

[[Page 4262]]

written notification of approval/disapproval of the alternative test 
method request under Sec.  63.7(f)(3), Sec.  60.8(b), or Sec.  
61.13(h)(1).

C. Recording and Publication

    As noted earlier, approvals for broadly applicable alternative test 
methods will be announced on the EPA's Web site at https://www.epa.gov/
ttn/emc/tmethods.html#CatB as soon as they are issued. The notification 
on our Technology Transfer Network (TTN) Web site will clearly indicate 
each class, category, or subcategory of sources for which the change or 
alternative test method is approved. We intend to publish a notice 
annually that summarizes approvals for broadly applicable alternative 
test methods.
    Table 1 in this notice includes a summary of broad approvals that 
have been posted to the TTN. Complete copies of these documents may be 
obtained at https://www.epa.gov/ttn/emc/tmethods.html#CatB.
