appropriate rule unless the owner or operator of the sources demonstrates to the Director,that the excess emissions are
a result of a malfunction. The Director shall consider,along with any other pertinent information,the criteria
contained in 15A NCAC 2D.0535(c)(1)through(7).
2. 15A NCAC 2D.0535(g). Excess emissions during start-up and shut-down shall be considered a violation of the

J. Emergency Provisions[40 CFR 70.6(g)]
The Permittee shall be subject to the following provisions with respect to emergencies:
1. An emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the
facility,including acts of God,which situation requires immediate corrective action to restore normal operation,and
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 meta
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 pen-nit;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.

accordance with 15A NCAC 2D.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

Permit 09006T04 Crushing and Screening Plant
Page 38
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.

i
Permit 09006T04 Crushing and Screening Plant j
Page 39
operator may be required to submit a fugitive dust plan as described in 2D.0540(f).
"Fugitive dust emissions"means particulate matter from process operations that does not pass through a process stack or

In addition to this notification requirement,with the next significant modification or Air Quality Permit renewal,
the Permittee shall submit a page"E5"of the application forms signed by the responsible official verifying that the
application for the 502(b)(10)change/modification,is true,accurate,and complete. Further note that
modifications made pursuant to 502(b)(10)do not relieve the Permittee from satisfying preconstruction
requirements.
I
00. Third Party Participation and EPA Review[15A NCAC 2Q .0521,.0522 and.0525(7)]
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 j
petition, the failure to object is the end of EPA's decision-making process with respect to the revisions to the permit.
