2D.1110 or.1111),or the operating permit provides for periodic(e.g.,quarterly)reporting of excess emissions,

Permit 08179T07
Page 30
reporting shall be performed as prescribed therein.
2. If the source is not subject to NSPS(15A NCAC 2D.0524),NESHAPS(15A NCAC 2D.1110 or.1111),or these

unavoidable increases in emissions attributable to the emergency. An emergency shall not include noncompliance
to the extenZcaused by improperly designed equipment,lack of preventive maintenance,careless or improper
operaVk,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;
