| (a) Flexible permit amendments. All representations
with regard to construction plans and operation procedures in an application
for a flexible permit or flexible permit amendment, as well as any
general and special conditions, become conditions upon which the subsequent
flexible permit is issued. Except as provided in §116.118 of
this title (relating to Construction While Permit Amendment Application
Pending), it shall be unlawful for any person to vary from such representation
or flexible permit provision if the change will cause a change in
the method of control of emissions or the character of the emissions,
will relax emission controls, or will result in a significant increase
in emissions unless application is made to the executive director
to amend the flexible permit in that regard and such amendment is
approved by the executive director or commission. Applications to
amend a flexible permit shall be submitted with a completed Form PI-1
and are subject to the requirements of §116.711 of this title
(relating to Flexible Permit Application).
(b) Flexible permit alterations.
(1) A flexible permit alteration is for any variation
from a representation in a flexible permit application or a general
or special provision of a flexible permit that does not require a
flexible permit amendment.
(2) All flexible permit alterations which may involve
a change in a general or special condition contained in the flexible
permit, or affect control equipment performance must receive prior
approval by the executive director. The executive director shall be
notified in writing of all other flexible permit alterations within
ten days of implementing the change, unless the permit provides for
a different method of notification. Any flexible permit alteration
request or notification shall include information sufficient to demonstrate
that the change does not interfere with the owner or operator's previous
demonstrations of compliance with the requirements of §116.711
of this title, including the protection of public health and welfare.
The appropriate commission regional office and any local air pollution
program having jurisdiction shall be provided copies of all flexible
permit alteration documents.
(3) Flexible permit alterations shall not be subject
to the requirements of best available control technology identified
in §116.711(2) of this title.
(c) Changes not requiring an amendment or alteration.
The following changes do not require an amendment or alteration, except
that an amendment is required if the change will cause a change in
the method of control of emissions or the character of the emissions,
will relax emission controls, will result in a significant increase
in emissions as determined under §116.718 of this title (relating
to Significant Emission Increase), or conflicts with an existing permit
condition:
(1) a change in throughput; or
(2) a change in feedstock.
(d) Permit by rule under Chapter 106 of this title
(relating to Permits by Rule) in lieu of permit amendment or alteration.
(1) Regardless of subsection (a) or (b) of this section,
no permit amendment or alteration is required if the changes to the
permitted facility qualify for a permit by rule under Chapter 106
of this title unless prohibited by permit provision as provided in §116.715
of this title (relating to General and Special Conditions). All such
changes permitted by rule to a permitted facility shall be incorporated
into that facility's permit at such time as the permit is amended
or renewed.
(2) Emission increases authorized by Chapter 106 of
this title at an existing facility authorized by a flexible permit
shall not cause an exceedance of the emissions cap or individual emission
limitation.
