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) in 2009.

FOR FURTHER INFORMATION CONTACT: An electronic copy of each alternative 
test method approval document is available on EPA's Web site at http://www.epa.gov/ttn/emc/approalt.html. For questions about this notice, 
contact Jason M. DeWees, 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-
9724; fax number: 919-541-0516; e-mail address: dewees.jason@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 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 http://www.epa.gov/ttn/emc/approalt.html.

II. Background

    This notice identifies EPA's broadly applicable alternative test 
method approval decisions issued between January 1, 2009, and December 
31, 2009, under the NSPS, 40 CFR part 60, and the NESHAP, 40 CFR parts 
61 and 63 (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 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

[[Page 7594]]

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 the 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). EPA will continue to announce approvals for 
broadly applicable alternative test methods on the EPA's Web site at 
http://www.epa.gov/ttn/emc/approalt.html and intends to publish a 
notice annually that summarizes approvals for broadly applicable 
alternative test methods.
    This notice comprises a summary of fourteen such approval documents 
added to our technology transfer network from January 1, 2009, through 
December 31, 2009. The alternative test method number, the reference 
method affected, sources allowed to use this alternative, and 
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 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 the 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.
