in accordance with 15A NCAC 2D .2600 and follow the procedures ou d below:
1. The Permittee shall submit a completed Protocol Submittal Form to th Regional Supervisor at least

Regional Supervisor.
2. The Permittee shall notify the Regional Supervis r of the spe - st dates at least 15 days prior to testing
in order to afford the DAQ the opportunity to have an obse a n-site during the sampling program.
3. During all sampling periods,the Permittee shall operate the mission source(s)under maximum normal
operating conditions or alternative ope n �testrepport
eemed appropriate by the Regional Supervisor
or his delegate.
4. The Permittee shall submit two coppiie�s of t e to the DAQ. The test report shall contain at a
minimum the following information:
a. a description of the trap mg and air testing'experience of the person directing the test;
b. a certification of th est results by sampling team leader and facility representative;
c a summary of e issions results anMext detailing the objectives of the testing program,the applicable
state and fede regulations,ix conclusions about the testing and compliance status of the emission
source(s);
d. a detailed description of th tested emission source(s)and sampling location(s)process flow diagrams,
engineering drawings, and sampling location schematics should be included as necessary;
e. all field, analytical, and calibration data necessary to verify that the testing was performed as specified
the�ppplicable test methods;
f example calculations for at least one test run using equations in the applicable test methods and all test
results including intermediate parameter calculations;and
g. documentation of facility operating conditions during all testing periods and an explanation relating
ese Aerating conditions to maximum normal operation. If necessary,provide historical process data
to verify maximum normal operation.
5. Th sting requirement(s)shall be considered satisfied only upon written approval of the test results by
the DAQ.
6. The DAQ will review emission test results with respect exclusively to the specified testing objectives as
proposed by the Permittee and approved by the DAQ.
KK.Reopening for Cause [15A NCAC 2Q .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

requirements as prescribed by the permit shall brim emented within the monitoring period.
MM. Fugitive Dust Control Requirement [15A NCAC 2 - STATE ENFORCEABLE ONLY
As required by 15A NCAC 2D .0540"krfticulates from Fugitive Dust Emission Sources,"the Permittee shall
not cause or allow fugitive dust emis ns to cause or contribute to substantive complaints or excess visible
emissions beyond the property boundary. hf 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). IF
"Fugitive dust emissions"means panic e matter from process operations that does not pass through a
