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 that EPA has made under and in support of New 
Source Performance Standards (NSPS) and the National Emission Standards 
for Hazardous Air Pollutants (NESHAP) in 2010.

FOR FURTHER INFORMATION CONTACT: For questions about this notice, 
contact 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; e-mail address: melton.lula@epa.gov.

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 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?

    Copies of the broadly applicable alternative test method approval 
documents are available from EPA's Web site at http://www.epa.gov/ttn/emc/approalt.html.

II. Background

    Broadly applicable alternative test method approval decisions made 
by EPA in 2010 under the NSPS, 40 CFR part 60 and the NESHAP, 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 EPA's Web site at http://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 experiences, 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 EPA's Web site at http://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 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 EPA's Web site at http://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 sixteen such approval documents 
added to our technology transfer network from January 1, 2010, through 
December 31, 2010. The alternative method decision letter or 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 EPA's Web site at 
http://www.epa.gov/ttn/emc/approalt.html as the table 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 issue 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 EPA's Web site at http://www.epa.gov/ttn/emc/approalt.html 
and in the subsequent Federal Register notice. If we should 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 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.

    Dated: February 15, 2011.

Acting Director, Office of Air Quality Planning and Standards.
