(i) An alternative reference test method or a deviation from a reference test method identified in this section may be approved as follows:
(A) The owner or operator of the Astaris-Idaho facility must submit a written request to the Regional Administrator at least 60 days before the performance test is scheduled to begin which includes the reasons why the alternative or deviation is needed and the rationale and data to demonstrate that the alternative test method or deviation from the reference test method:
(1) Provides equal or improved accuracy and precision as compared to the specified reference test method; and
(2) Does not decrease the stringency of the standard as compared to the specified reference test method.
(B) If requested by EPA, the demonstration referred to in paragraph (d)(5)(i)(A) of this section must use Method 301 in 40 CFR part 63, appendix A to validate the alternative test method or deviation.
(C) The Regional Administrator must approve the request in writing.
(ii) Until the Regional Administrator has given written approval to use an alternative test method or to deviate from the reference test method, the owner or operator of the Astaris-Idaho facility is required to use the reference test method when conducting a performance test pursuant to paragraph (e)(1) of this section.
(6) For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any requirement of this section, nothing in this section shall preclude the use, including the exclusive use, of any credible evidence or information relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or reference test or procedure had been performed.
