days after sample collection unless otherwise specified in the specific conditions. The owner or
operator may request an extension to submit the final test report.The Director shall approve an
extension request if he finds that the extension request is a result of actions beyond the control of the
owner or operator.
a. The Director shall make the final determination regarding any testing procedure deviation and
the validity of the compliance test.The Director may:
i. Allow deviations from a method specified under a rule in this Section if the owner or
operator of the source being tested demonstrates to the satisfaction of the Director that the
specified method is inappropriate for the source being tested.
ii. Prescribe alternate test procedures on an individual basis when he finds that the alternative
method is necessary to secure more reliable test data.
iii. Prescribe or approve methods on an individual basis for sources or pollutants for which no
test method is specified in this Section if the methods can be demonstrated to determine
compliance of permitted emission sources or pollutants.
b. The Director may authorize the Division of Air Quality to conduct independent tests of any
source subject to a rule in this Subchapter to determine the compliance status of that source or to
verify any test data submitted relating to that source.Any test conducted by the Division of Air
Quality using the appropriate testing procedures described in Section 02D .2600 has precedence
over all other tests.
