during the period of air testing. The owner or operator of the source shall ensure that the equipment
or process being tested is operated at the production rate that best fulfills the purpose of the test. The
individual conducting the emission test shall describe the procedures used to obtain accurate process
data and include in the test report the average production rates determined during each testing
period.
4. Two copies of the final air emission test report shall be submitted to the Director not later than 30
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:
(1) 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.
(2) Prescribe alternate test procedures on an individual basis when he finds that the alternative
method is necessary to secure more reliable test data.
(3) 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 2D .2600 has precedence over all
other tests.

For permits modifications subject to 45-day review by the federal Environmental Protection Agency
(EPA), EPA's decision to not object to the proposed permit is considered final and binding on the
EPA and absent a third party petition, the failure to object is the end of EPA`s decision-making
process with respect to the revisions to the permit. The time period available to submit a public
petition pursuant to 15A NCAC 2Q .0518 begins at the end of the 45-day EPA review period.
