bagfilter) and vents from a building that encloses affected PM Method 5
facilities (except for a system that controls an individual
enclosed storage bin)
Affected facilities with dry capture systems (i.e., Visible Method 9
bagfilter) and a building that encloses affected facilities Emissions
=Emins
Crushers Feth:o�d�
Fugitive-emissions from conveyor belts, screening Visible Method 9
operations, and other affected facilities Emissions
i. All performance tests shall be conducted in accordance with EPA Reference
Methods, contained in 40 CFR 60, Appendix A;
ii. The EPA Administrator retains the exclusive right to approve equivalent and
alternative test methods, continuous monitoring procedures, and reporting
requirements;
iii. Within 60 days after achieving the maximum production rate at which the
affected facility(s)will be operated,but not later than 180 days after the
initial start-up of the affected facility(s),the Permittee shall conduct the
required performance test(s) and submit two copies of a written report of the
test(s)to the Regional Supervisor, DAQ;
iv. The Permittee shall be responsible for ensuring,within the limits of
practicality,that the equipment or process being tested is operated at or near
its maximum normal production rate or at a lesser rate if specified by the
Director or his delegate;

Permit No. 09987R02
Page 12
V. All associated testing costs are the responsibility of the Permittee;
vi. The Permittee shall.arrange for air emission testing protocols to be provided
to the DAQ prior to testing. Testing protocols are not required to be pre-
approved by the DAQ prior to testing. The DAQ shall review testing
protocols for pre-approval prior to testing if requested by the Permittee at
least 45 days before conducting the test; and
vii. To afford the Regional Supervisor, DAQ,the opportunity to have an observer
present,the Permittee shall PROVIDE the Regional Office, in WRITING, at
least 7 days notice of any required performance test(s)that involve only
Method 9. All other tests require a 30 day notice.
viii. When determining compliance with the visible emissions limit for a dry
capture system(i.e., bagfilter)that controls an individual enclosed storage
bin,the duration of the Method 9 test shall be one (1)hour (ten 6-minute
averages).
ix. When determining compliance with the visible emissions limit from fugitive
emissions from crushers, conveyor belts, screening operations, and other
affected facilities (as described in 60.672(b) or 60.672(e)(1)), the duration of
the Method 9 test must be 30 minutes (five 6-minute averages). Compliance
with the fugitive visible emissions limits must be based on the average of the
five 6-minute averages.
X. For any affected facility that commenced construction, modification, or
reconstruction on or after April 22, 2008 that does not use wet suppression to
control emissions,the Permittee shall repeat the performance tests within five
(5) years of the previous test.
A. If an affected facility relies on water carryover from upstream wet
suppression to control fugitive emissions,then that affected facility is
exempt from the 5-year repeat testing requirement provided that the
Permittee conducts periodic inspections of the upstream wet
suppression that is responsible for controlling fugitive emissions from
the affected facility and designates which upstream wet suppression
systems will be periodically inspected at the time of the initial
performance test.
xi. If a building encloses affected facilities that commenced construction
modification, or reconstruction on or after April 22, 2008,the Permittee must
conduct an initial Method 9 performance test.
xii. If a building encloses only affected facilities that commenced construction,
modification, or reconstruction before April 22, 2008, and the Permittee has
not previously conducted an initial visible emissions performance test,then
the Permittee must conduct an initial Method 9 performance test to show
compliance with the above limits.

conditions, shall:
a. Notify the Director or his designee of any such occurrence by 9:00 a.m. Eastern time
of the Division's next business day of becoming aware of the occurrence and
describe:
i. the name and location of the facility,
ii. the nature and cause of the malfunction or breakdown,
iii. the time when the malfunction or breakdown is first observed,
iv. the expected duration, and
V. an estimated rate of emissions.
b. Notify the Director or his designee immediately when the corrective measures have
been accomplished.

Environmental Management Commission Regulations.
10. FUGITIVE DUST CONTROL REQUIREMENT -As required by 15A NCAC 2D .0540
"Particulates from Fugitive Dust Emission Sources," the Permittee shall not cause or allow
fugitive dust emissions to cause or contribute to substantive complaints or excess visible
emissions beyond the property boundary. If substantive complaints or excessive fugitive
dust emissions from the facility are observed beyond the property boundaries for six minutes
in any one hour(using Reference Method 22 in 40 CFR,Appendix A),the owner or
operator may be required to submit a fugitive dust plan as described in 2D .0540(f).
"Fugitive dust emissions" means particulate matter that does not pass through a process
stack or vent and that is generated within plant property boundaries from activities such as:
unloading and loading areas,process areas stockpiles, stock pile working,plant parking lots,
and plant roads (including access roads and haul roads).

down the engine in order to perform the management practice requirements
on the schedules required in Sections b.i., b.ii., and b.iii., above, or if
performing the management practice on the required schedules would
otherwise pose an unacceptable risk under federal, state or local law,the
management practices can be.delayed until the emergency is over or the
unacceptable disk under federal, state, or local law has abated. The
management practice shall be performed as soon as possible after the
emergency has ended or the unacceptable risk has abated. The Permittee shall

including associated air pollution control equipment and monitoring
equipment, in a manner consistent with safety and good air pollution control
practices for minimizing emissions. The general duty to minimize emissions
does not require the Permittee to make any farther efforts to reduce emissions
if levels required by this standard have been achieved. Determination of
whether such operation and maintenance procedures are being used will be
based on information available to DAQ which may include,but is not limited
to, monitoring results,review of operation and maintenance procedures,
review of operation and maintenance records, and inspection of the source.

Permittee shall change the oil within two (2) business days of receiving the results of
the analysis. If the engine is not in operation when the results of the analysis are
received,then the oil must be changed within two (2) business days or.before
commencing operation, whichever is later.
i. Total base number is less than 30 percent of the total base number of the oil
when new; or
ii. Viscosity of the oil has changed by more than 20 percent from the,viscosity
of the oil when new; or
iii. Water content(by volume) is greater than 0.5%.
If all of the above limits are not exceeded,the Permittee is not required to change the
oil before continuing to use the engine.
