JJ. General Emissions Testing and Reporting Requirements[15ANCAC 2Q.0508(i)(16)]
Emission compliance testing shalt be by the procedures of Section.2600,except as maybe otherwise required in Rules.0524,
.0912,.1110,.1111,or.1415 of Subchapter 2D.If emissions testing is required by this permit or the DAQ or if the Permittee
submits emissions testing to the DAQ to demonstrate compliance,the Pennittee shall perform such testing in accordance with
15A NCAC 213.2600 and follow the procedures outlined below:
1. The owner or operator of the source shall arrange for air emission testing protocols to be provided to the Director prior to
air pollution testing.Testing protocols are not required to be pre-approved by the Director prior to air pollution testing.
The Director shall review air emission testing protocols for pre-approval prior to testing if requested by the owner or
operator at least 45 days before conducting the test.
2. Any person proposing to conduct an emissions test to demonstrate compliance with an applicable standard shall notify
the Director at least 15 days before beginning the test so that the Director may at his option observe the test.
3. The owner or operator of the source shall arrange for controlling and measuring the production rates 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 fmds 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.
