Please be advised, that for Part 75 sources, beginning on March 27, 2012, testing as detailed in the rule must be conducted utilizing an Air Emission Testing Body (AETB). AETBs must be certified to operate in conformance with ASTM D7036. Except for a failure to have the testing overseen by a Qualified Individual (QI), a failure to conform to all of the ASTM D7036 requirements shall not be the sole reason to invalidate applicable Part 75 testing. Please see the Federal Register/Vol.76, No.59/Monday, March 28, 2011/Rules and Regulations. One important section is included below.

75.21

(f) Requirements for Air Emission testing. On and after March 27, 2012, relative accuracy testing under § 75.74(c)(2)(ii), section 6.5 of appendix A to this part, and section 2.3.1 of appendix B to this part, and stack testing under § 75.19 and section 2.1 of appendix E to this part shall be performed by an ''Air Emission Testing Body'', as defined in § 72.2 of this chapter. Conformance to the requirements of ASTM D7036*04 (incorporated by reference, see § 75.6), referred to in section 6.1.2 of appendix A to this part, shall apply only to these tests.
