Federal Register / Vol. 86, No. 24 / Monday, February 8, 2021 / Notices
before electing to employ any alternative method.
III. Approved Alternative Test Methods and Modifications To Test Methods This notice specifies four broadly applicable alternative test methods that the EPA approved between January 1, 2020, and December 31, 2020. The alternative method decision letter/
memo designation numbers, test methods affected, sources allowed to use this alternative, and method modifications or alternative methods allowed are summarized in Table 1 of this notice. A summary of approval documents was previously made available on our Technology Transfer Network between January 1, 2020, and December 31, 2020. For more detailed information, please refer to the complete copies of these approval documents
available at https www.epa.gov/emc/
broadly-applicable-approvedalternative-test-methods.
As also explained in our January 30, 2007 notice, we will revisit approvals of alternative test methods in response to written requests or objections indicating that a particular approved alternative test method either should not be broadly applicable or that its use is not appropriate or should be limited in some way. Any objection to a broadly applicable alternative test method, as well as the resolution of that objection, will be announced at https
www.epa.gov/emc/broadly-applicableapproved-alternative-test-methods and in a subsequent Federal Register notice.
If we decide to retract a broadly applicable test method, we will likely consider the need for an appropriate transition period for users either to
request case-by-case approval or to transition to an approved method.
This notice also announces our removal of ALT109 as a broadly applicable alternative test method from the Broadly Applicable Approved Alternative Test Methods web page. In the February 10, 2016 Federal Register notice 81 FR 7092, we announced the approval of ALT109 as an alternative method that would allow the use of digital photographs as a compliance option for specific recordkeeping requirements in Method 22. On November 14, 2018, we incorporated this compliance option into Method 22
83 FR 56713. Therefore, ALT109 is no longer an alternative test method.
Dated: January 15, 2021.
