53. Provisions concerning modification 

of such methods by users are specified 

under Section 2.8 (Modifications of 

Methods by Users) of Appendix C to 40 

CFR Part 58. 

In general, a method designation 

applies to any sampler or analyzer 

which is identical to the sampler or 

analyzer described in the application for 

designation. In some cases, similar 

samplers or analyzers manufactured 

prior to the designation may be 

upgraded or converted (e.g., by minor 

modification or by substitution of the 

approved operation or instruction 

manual) so as to be identical to the 

designated method and thus achieve 

designated status. The manufacturer 

should be consulted to determine the 

feasibility of such upgrading or 

conversion. 

Part 53 requires that sellers of 

designated reference or equivalent 

method analyzers or samplers comply 

with certain conditions. These 

conditions are specified in 40 CFR 53.9. 

Aside from occasional breakdowns or 

malfunctions, consistent or repeated 

noncompliance with any of these 

conditions should be reported to: 

Director, Human Exposure and 

Atmospheric Sciences Division (MD– 

E205–01), National Exposure Research 

Laboratory, U.S. Environmental 

Protection Agency, Research Triangle 

Park, North Carolina 27711. 

Designation of these new equivalent 

methods is intended to assist the States 

in establishing and operating their air 

quality surveillance systems under 40 

CFR Part 58. Questions concerning the 

commercial availability or technical 

aspects of the method should be 

directed to the applicant.
