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 at 
                    *www.epa.gov/​ttn/​emc/​approalt.html.* II. Background Broadly applicable alternative test method approval decisions made by the EPA in 2015 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 in lieu of otherwise specified reference test methods. 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 located 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 source-specific 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 circumstances. Source owners or operators should review the specific broadly applicable alternative method approval decision at 
                    *www.epa.gov/​ttn/​emc/​approalt.html*
                     before electing to employ it. As per section 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 publish a notice annually that summarizes approvals for broadly applicable alternative test methods. This notice comprises a summary of five such approval documents posted to our Technology Transfer Network dated between January 1, 2015, and December 31, 2015. 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 or that its use should in some way be limited, 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. Dated: January 19, 2016. Stephen D. Page, Director, Office of Air Quality Planning and Standards.
