Recent Postings of Broadly Applicable Alternative Test Methods

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.


SUMMARY: This notice announces the broadly applicable alternative test 
method approval decisions the EPA has made under and in support of New 
Source Performance Standards (NSPS), the National Emission Standards 
for Hazardous Air Pollutants (NESHAP), and the Consolidated Federal Air 
Rule under the Clean Air Act (CAA) in 2013.

FOR FURTHER INFORMATION CONTACT: An electronic copy of each alternative 
test method approval document is available on the EPA's Web site at 
www.epa.gov/ttn/emc/approalt.html. For questions about this notice, 
contact Ms. Lula H. Melton, 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-
2910; fax number: 919-541-0516; email address: [email protected]. For 
technical questions about individual alternative test method decisions, 
refer to the contact person identified in the individual approval 


I. General Information

A. Does this notice apply to me?

    This notice will be of interest to entities regulated under 40 Code 
of Federal Regulations (CFR) parts 60, 61, 63, and 65, state, local, 
and tribal agencies, and the EPA Regional Offices responsible for 
implementation and enforcement of regulations under 40 CFR parts 60, 
61, 63, and 65.

B. How can I get copies of this information?

    You may access copies of the broadly applicable alternative test 
method approval documents from the EPA's Web site at www.epa.gov/ttn/emc/approalt.html.

II. Background

    Broadly applicable alternative test method approval decisions made 
by the EPA in 2013 under the NSPS, 40 CFR part 60, the NESHAP, 40 CFR 
parts 61 and 63, and the Consolidated Federal Air Rule, 40 CFR part 65 
are identified in this notice (see Table 1). Source owners and 
operators may voluntarily use these broadly applicable alternative test 
methods subject to their specific applicability. Use of these broadly 
applicable alternative test methods does not change the applicable 
emission standards.
    As explained in a previous Federal Register notice published at 72 
FR 4257 (January 30, 2007) and found on the EPA's Web site at 
www.epa.gov/ttn/emc/approalt.html, 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 sections 60.8(b)(3), 61.13(h)(1)(ii), and 63.7(e)(2)(ii). A similar 
authority is granted in 40 CFR part 65 under section 65.158(a)(2). In 
the past, we have performed thorough technical reviews of numerous 
requests for alternatives and modifications to test methods and 
procedures. Based on these reviews, we have often found that 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 an 
alternative method is 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 
    It is important to clarify that alternative methods are not 
mandatory but permissive. Sources are not required to employ such a 
method but may choose to do so in appropriate cases. Source owners or 
operators should review the specific broadly applicable alternative 
method approval decision on the EPA's Web site at www.epa.gov/ttn/emc/approalt.html before electing to employ it. As per 63.7(f)(5), by 
electing to use an alternative method for 40 CFR part 63 standards, the 
source owner or operator must continue to use the alternative method 
until approved otherwise.
    The criteria for approval and procedures for submission and review 
of broadly applicable alternative test methods are outlined at 72 FR 
4257 (January 30, 2007). We will continue to announce approvals for 
broadly applicable alternative test methods at www.epa.gov/ttn/emc/approalt.html and annually publish a notice that summarizes approvals 
for broadly applicable alternative test methods.
    This notice comprises a summary of seven such approval documents 
added to our Technology Transfer Network from January 1, 2013, through 
December 31, 2013. The alternative method decision letter/memo number, 
the reference method affected, sources allowed to use this alternative, 
and the modification or alternative method allowed are summarized in 
Table 1 of this notice. Please refer to the complete copies of these 
approval documents available at www.epa.gov/ttn/emc/approalt.html as 
Table 1 serves only as a brief summary of the broadly applicable 
alternative test methods.
    If you are aware of reasons why a particular alternative test 
method approval that we issued should not be broadly applicable, we 
request that you make us aware of the reasons in writing, and we will 
revisit the broad approval. Any objection to a broadly applicable 
alternative test method, as well as the resolution of that objection, 
will be announced at www.epa.gov/ttn/emc/approalt.html and in the 
subsequent Federal Register notice. If we decide to retract a broadly 
applicable test method, we would continue to grant case-by-case 
approvals, as appropriate, and would (as states, local and tribal 
agencies and the EPA Regional Offices 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.

Acting Director, Office of Air Quality Planning and Standards.
