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 the 

Environmental Protection Agency (EPA) 

made under and in support of New 

Source Performance Standards (NSPS) 

and the National Emission Standards for 

Hazardous Air Pollutants (NESHAP) 

between January 1, 2020, and December 

31, 2020. This notice also announces the 

removal of a previously approved 

broadly applicable alternative test 

method. 

FOR FURTHER INFORMATION CONTACT: An 

electronic copy of each alternative test 

method approval document is available 

at https://www.epa.gov/emc/broadlyapplicable-approved-alternative-testmethods. For questions about this 

notice, contact Mrs. 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 document(s). 

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 59, 60, 

61, 63 and 65; state, local, and tribal 

agencies; and the EPA Regional offices 

responsible for implementation and 

enforcement of regulations under 40 

CFR parts 59, 60, 61, 63, and 65. 

B. How can I get copies of this 

information? 

You may access copies of the broadly 

applicable alternative test method 

approval documents at https://

www.epa.gov/emc/broadly-applicableapproved-alternative-test-methods. 

II. Background 

This notice identifies broadly 

applicable alternative test methods that 

the EPA approved in 2020 under the 

New Source Performance Standards 

(NSPS), 40 CFR part 60, and the 

National Emission Standards for 

Hazardous Air Pollutants (NESHAP) 

programs, 40 CFR parts 61 and 63. See 

Table 1 of this notice for the summary 

of these test methods. Source owners 

and operators may voluntarily use these 

broadly applicable alternative test 

methods in lieu of otherwise required 

test methods or related testing 

procedures. Use of these broadly 

applicable alternative test methods are 

not intended to and should not change 

the applicable emission standards. This 

notice also announces the removal of 

ALT–109 as an approved broadly 

applicable alternative test method given 

our subsequent revisions to certain 

requirements in Method 22. 83 FR 

56713 (November 14, 2018). 

The Administrator has the authority 

to approve the use of alternative test 

methods for compliance with 

requirements under 40 CFR parts 60, 61, 

and 63. This authority is found in 40 

CFR 60.8(b)(3), 61.13(h)(1)(ii), and 

63.7(e)(2)(ii). Additional and similar 

authority can be found in 40 CFR 

59.104(f) and 65.158(a)(2). The criteria 

for approval and procedures for 

submission and review of broadly 

applicable alternative test methods are 

explained in a previous Federal 

Register notice published at 72 FR 4257 

(January 30, 2007) and located at 

https://www.epa.gov/emc/broadlyapplicable-approved-alternative-testmethods. As explained in this notice, 

we will announce approvals for broadly 

applicable alternative test methods at 

https://www.epa.gov/emc/broadlyapplicable-approved-alternative-testmethods as they are issued and publish 

an annual notice that summarizes 

approvals for broadly applicable 

alternative test methods during the 

preceding year. 

As also explained in the January 30, 

2007 notice, our approval decisions 

involve 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 modifications 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 equitable and efficient to 

simultaneously approve its use for all 

appropriate sources and situations. 

Use of approved alternative test 

methods are not mandatory but rather 

permissive. Sources are not required to 

employ such a method but may choose 

to do so in appropriate circumstances. 

As specified in 40 CFR 63.7(f)(5), 

however, a source owner or operator 

electing to use an alternative method for 

40 CFR part 63 standards must continue 

to use the alternative method until 

otherwise authorized. Source owners or 

operators should, therefore, review the 

specific broadly applicable alternative 

method approval decision at https://

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 ALT–109 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 ALT–109 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, ALT–109 is 

no longer an alternative test method. 

Dated: January 15, 2021.

Director, Office of Air Quality Planning and 

Standards.

Certain New Chemicals or Significant 

New Uses; Statements of Findings for 

August 2019 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: Section 5(g) of the Toxic 

Substances Control Act (TSCA) requires 

EPA to publish in the Federal Register 

a statement of its findings after its 

review of TSCA section 5(a) notices 

when EPA makes a finding that a new 

chemical substance or significant new 

use is not likely to present an 

unreasonable risk of injury to health or 

the environment. Such statements apply 

to premanufacture notices (PMNs), 

microbial commercial activity notices 

(MCANs), and significant new use 

notices (SNUNs) submitted to EPA 

under TSCA section 5. This document 

presents statements of findings made by 

EPA on TSCA section 5(a) notices 

during the period from August 1, 2019 

to August 31, 2019.
