that causes the facility to exceed a technology-based emission limitation under the permit,due to unavoidable
increases in emissions attributable to the emergency. An emergency shall not include noncompliance to the extent
caused by improperly designed equipment,lack of preventive maintenance,careless or improper operation,or operator
error.
2. An emergency constitutes an affirmative defense to an action brought for noncompliance with such technology-based
emission limitations if the conditions specified in 3.below are met.
3. The affirmative defense of emergency shall be demonstrated through properly signed contemporaneous operating logs
or other relevant evidence that include information as follows:
a. an emergency occurred and the Permittee can identify the cause(s)of the emergency;
b. the permitted facility was at the time being properly operated;
c. during the period of the emergency the Permittee took all reasonable steps to minimize levels of emissions that
exceeded the standards or other requirements in the permit;and
d. the Permittee submitted notice of the emergency to the DAQ within two working days of the time when emission
limitations were exceeded due to the emergency. This notice must contain a description of the emergency,steps
taken to mitigate emissions,and corrective actions taken.

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.
