3. ANNUAL FEE PAYMENT-Pursuant to 15A NCAC 2Q .0203(a), the Permittee shall pay the annual
permit fee within 30 days of being billed by the DAQ. Failure to pay the fee in a timely manner will
cause the DAQ to initiate action to revoke the permit.
4. ANNUAL EMISSION INVENTORY REQUIREMENTS—The Permittee shall report by June 30 of
each year the actual emissions of each air pollutant listed in 15A NCAC 02Q .0207(a) from each
emission source within the facility during the previous calendar year. The report shall be in or on such
form as may be established by the Director. The accuracy of the report shall be cert' d by the
responsible official of the facility.
5. EQUIPMENT RELOCATION-A new air permit shall be obtained by the itt prior
establishing,building, erecting,using, or operating the emission sourc air ng equi ent at a
site or location not specified in this permit. op
6. This permit is subject to revocation or modification by the DA upon a ermination that information
contained in the application or presented in the support thereof i incorrect, conditions under which
this permit was granted have changed, or violations of conditions contained in this permit have
occurred. The facility shall be properly operated and maintained at all times in a manner that will
effect an overall reduction in air pollution. Unless otherwise specified by this permit,no emission
source may be operated without the concurren operation of its associated air cleaning device(s) and
appurtenances.
7. REPORTING REQUIREMENT -Any ofthe llowing h ould result in previously unpermitted,
new, or increased emissions must be reported to't e Re onal Supervisor, DAQ:
a. changes in the information submitted in the ication regarding facility emissions;
b. changes that modify equipment or processes of existing permitted facilities; or
c. changes in the quantity quality of materials processed.an
