c. Monitoring Approach The key elements of the monitoring approach for particulate matter,including
parameters to be monitored,parameter ranges and performance criteria are presented in the following table.

Measurement Approach Visible emissions from the fabric filter Pressure drop across the fabric filter is

II. Indicator Range An excursion is defined as visible An excursion is defined as a pressure drop

or malfunction. Excursions trigger an
inspection,corrective action,and a
reporting requirement.
QIP Threshold The QIP threshold is an accumulation of None selected
excursions exceeding 1 percent duration
of the operating time for a six-month
rcpmrting period.
III. Performance Criteria

F. Avera in Periods NA NA
d. Justification
i. Background. The pollutant-specific emission units are the six identical stoker boilers used to produce
steam(a portion of which is sold to a nearby industrial facility for use in their process). The remainder
of the steam is used to drive a steam turbine connected to an electrical generator to generate electricity
for wholesale to the connected utility. The particulate matter emissions from each boiler are controlled
by fabric filters with approximately 16,800 square feet of filter area,each.
ii. Rationale for Selection of Performance Indicators. Visible emissions was selected as the performance
indicator because it is a good indicator of the proper operation and maintenance of the filter units.
When the filter units are operating properly,there will not be any visible emissions in the exhaust
outlet.Any increase in visible emissions indicates reduced performance of the filter units,therefore,the
presence of visible emissions in levels exceeding or equal to 15%(six-minute average),excluding
periods of start-up,shutdown or malfunction,is used as a performance indicator.

Air Quality Permit No. 05884T21
Page 17
In general,filters are designed to operate at a relatively constant pressure drop. Monitoring pressure
drop provides a means of detecting a change in operation that could lead to an increase in emissions.
An increase in pressure drop can indicate that the cleaning cycle is not frequent enough,cleaning
equipment is damaged/broken,the bags are becoming blinded,or the airflow has increased. A decrease
in pressure drop may indicate broken or loose bags,but this is also indicated by the presence of visible
emissions,indicator No. 1. A pressure drop across the filter unit also serves to indicate that there is
airflow through the control device.
iii. Rationale for Section of Indicator Ranges. Per operating knowledge of the systems,the facility has
selected an indicator range of greater than or equal to 15%opacity(six-minute average),excluding
periods of start-up,shutdown or malfunction. When an excursion occurs,corrective action will be
initiated,beginning with an evaluation of the occurrence to determine the action required to correct the
situation. All excursions will be documented and reported. This indicator range was selected because:
(1)an increase in visible emissions is indicative of an increase in particulate emissions;and(2)a
COMB is a well-established monitoring technique for these sources.
The selected QIP threshold for fabric filter visible emissions is an accumulation of excursions
exceeding 1 percent duration of the operating time for a six-month reporting period. If the QIP
threshold is exceeded in a semiannual reporting period,a QIP will be developed and implemented.
The indicator range chosen for the fabric filter pressure drop is greater than 9.5 inches water. An
excursion triggers an inspection,corrective action,and a reporting requirement. The pressure drop is
recorded daily. As the pressure drop approaches 9.5 inches water the bags are scheduled for
replacement.
Reporting[15A NCAC 02Q .0508(f)]
e. The Permittee shall submit a summary report of all monitoring activities postmarked on or before January
30 of each calendar year for the preceding six-month period between July and December and July 30 of
each calendar year for the preceding six-month period between January and June. The report shall also

(i) Summary information on the number,duration and cause(including unknown cause, if applicable)of
excursions or exceedances,as applicable,and the corrective actions taken;
(ii) Summary information on the number,duration and cause(including unknown cause,if applicable)for
monitor downtime incidents(other than downtime associated with zero and span or other daily
calibration checks,if applicable);and
(iii)A description of the actions taken to implement a QIP during the reporting period as specified in§64.8.
Upon completion of a QIP,the owner or operator shall include in the next summary report
documentation that the implementation of the plan has been completed and reduced the likelihood of
similar levels of excursions or exceedances occurring.
All instances of deviations for the requirements of this permit must be clearly identified.

H. Ambient Air Ouality Standards [15A NCAC 02D .0501(c)]
In addition to any control or manner of operation necessary to meet emission standards specified in this
permit, any source of air pollution shall be operated with such control or in such manner that the source
shall not cause the ambient air quality standards in 15A NCAC 02D .0400 to be exceeded at any point
beyond the premises on which the source is located. When controls more stringent than named in the
applicable emission standards in this permit are required to prevent violation of the ambient air quality
standards or are required to create an offset,the permit shall contain a condition requiring these controls.
JJ. General Emissions Testing and Regortin2 Requirements [15A NCAC 02Q .0508(i)(16)]
Emission compliance testing shall be by the procedures of Section .2600, except as may be otherwise
required in Rules .0524, .0912, .1110, .1111, or.1415 of Subchapter 02D. 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 Permittee shall perform such testing in accordance with 15A NCAC 02D
.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 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:
i. 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.
ii. Prescribe alternate test procedures on an individual basis when he finds that the
alternative method is necessary to secure more reliable test data.
iii. 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 02D .2600 has
precedence over all other tests.

KK.Reopening for Cause [15A NCAC 02Q .0517]
1. A permit shall be reopened and revised under the following circumstances:
a. additional applicable requirements become applicable to a facility with remaining permit term
of three or more years;
b. additional requirements(including excess emission requirements)become applicable to a
source covered by Title IV;
c. the Director or EPA finds that the permit contains a material mistake or that inaccurate
statements were made in establishing the emissions standards or other terms or conditions of the
permit; or
d. the Director or EPA determines that the permit must be revised or revoked to assure compliance
with the applicable requirements.
2. Any permit reopening shall be completed or a revised permit issued within 18 months after the
applicable requirement is promulgated. No reopening is required if the effective date of the
requirement is after the expiration of the permit term unless the term of the permit was extended
pursuant to 15A NCAC 02Q .0513(c).
3. Except for the state-enforceable only portion of the permit,the procedures set out in 15A NCAC
02Q .0507, .0521,or.0522 shall be followed to reissue the permit. If the State-enforceable only
portion of the permit is reopened,the procedures in 15A NCAC 02Q .0300 shall be followed. The
proceedings shall affect only those parts of the permit for which cause to reopen exists.
4. The Director shall notify the Permittee at least 60 days in advance of the date that the permit is to be

MM.Fugitive Dust Control Requirement[15A NCAC 02D .0540] - STATE ENFORCEABLE ONLY
As required by 15A NCAC 02D .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 02D.0540(f).
"Fugitive dust emissions"means particulate matter from process operations 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).

a. a description of the change at the facility;
b. the date on which the change will occur;
C. any change in emissions; and
d. any permit term or condition that is no longer applicable as a result of the change.
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.
00. Third Party Participation and EPA Review [15A NCAC 02Q .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 petition,the failure to object is the end of EPA's decision-making
process with respect to the revisions to the permit. The time period available to submit a public
petition pursuant to 15A NCAC 02Q .0518 begins at the end of the 45-day EPA review period.
