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) and the National Emission Standards 
for Hazardous Air Pollutants (NESHAP) under the Clean Air Act (CAA) in 
2012.

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: melton.lula@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 notice apply to me?

    This notice will be of interest to entities regulated under 40 Code 
of Federal Regulations (CFR) parts 60, 61, and 63, state, local, and 
tribal agencies, and the 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 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 2012 under the NSPS, 40 CFR part 60 and the NESHAP, and 
40 CFR parts 61 and 63 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). 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 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.
    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 on the EPA's Web site 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, 2012, through 
December 31, 2012. 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 from the EPA's Web site at www.epa.gov/ttn/emc/approalt.html as Table 1 serves only as a brief summary of the 
broadly applicable alternative test methods. In addition to alternative 
decisions listed in Table 1, we received comments and updated 
Alternative-082, which was approved the previous year in 2011. This 
alternative approval letter can also be viewed at www.epa.gov/ttn/emc/approalt.html.
    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 on the EPA's Web site 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

[[Page 11175]]

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.
