Background
Federal emissions standards typically specify performance test methods and monitoring
Specific source, or other stakeholder group, may need or want to use alternative to required test method or monitoring

Relevant Regulations, cont.
Administrator’s authority to approve alternatives to test methods and monitoring requirements is codified in General Provisions to Parts 60, 61, & 63Test Methods - §§60.8(b), 61.18(h), 63.7(f)Monitoring - §§60.13(l), 61.14(g), 63.8(f)

Test Method vs. Monitoring
Section 63.2 defines test method as a “validated procedure for sampling, preparing, and analyzing for an air pollutant specified in a relevant standard as the performance test procedure.”
In actuality, the test procedure used to determine compliance could be a test method or a monitoring procedure E.g., Subpart Da SO2 and NOx CEMS
performance specifications and QA procedures

Definition: Minor Change to Test Method
Site-specific No national significance No effect on stringency of standard Made to accommodate site-specific
constraints
![Page 10: Alternative Test Method and Monitoring Approval Robin Segall Measurement Technology Workshop December 6 – 8, 2010](https://reader035.vdocuments.net/reader035/viewer/2022062619/5518c21655034638098b4992/html5/thumbnails/10.jpg)
Definition:Intermediate Change to Test Method
Modification involves proven technology
Site-specific, but could have national significance
Potential to decrease stringency of standard, but demonstrated that will not

Definition: Major Change to Test Method
Modification is an entirely new method and/or involves unproven technology
May be site-specific, but will usually set a national precedent
Broadly applicable

Delegation to States/Locals
Policy codified in 40 CFR 63, Subpart ERegions may delegate to S/L approval
authority for:• Minor changes to test methods and
monitoring - typically done• Intermediate changes to test methods
and monitoring, where appropriate

Criteria for Approval of Alternative Test Methods Must produce results adequate for the
Administrator’s determination of compliance From definition of alternative method in General
Provisions to 40 CFR Parts 60, 61, and 63
That has been demonstrated to the Administrator’s satisfaction using Method 301 From definition of alternative test method in General
Provisions to 40 CFR Part 63 Applies to intermediate and major changes
![Page 19: Alternative Test Method and Monitoring Approval Robin Segall Measurement Technology Workshop December 6 – 8, 2010](https://reader035.vdocuments.net/reader035/viewer/2022062619/5518c21655034638098b4992/html5/thumbnails/19.jpg)
Criteria for Approval of Alternative Monitoring Like an alternative method, alternative
monitoring must allow the Administrator to make adequate determination of compliance
Examples of approvable alternative monitoring are included in §§60.13(l), 61.14(g), and 63.8(f)
New approvals should be consistent with prior approvals Applicability Determination index Consultation with other Regions and OECA
