    B.5.  Insignificant Activities List. Those activities listed
in the following table are approved by the permitting
authority as insignificant on the basis of size, emission or
production rate, or type of pollutant. By such listing,
the permitting authority exempts certain sources or types of
sources from the requirement to obtain a permit under this
Chapter unless it is determined by the permitting authority
on a site-specific basis that any such exemption is not
appropriate. The listing of any activity or emission unit as
insignificant does not authorize the maintenance of a
nuisance or a danger to public health or safety. Any activity
for which a federal applicable requirement applies is not
insignificant, even if the activity meets the criteria below.
For the purpose of permitting requirements under LAC
33:III.507, no exemption listed in the following table shall
become effective until approved by the administrator in
accordance with 40 CFR Part 70. For purposes of the
insignificant activities listed in this Paragraph, aggregate
emissions shall mean the total emissions from a particular
insignificant activity or group of similar insignificant
activities (e.g., A.1, A.2, etc.) within a permit per year.

D.  Exemptions Based on Emissions Levels
The owner or operator of any source may apply for an exemption from the
permitting requirements of this Chapter for any emissions unit provided
each of the following criteria are met. Activities or emissions units
exempt as insignificant based on these criteria shall be included in the
permit at the next renewal or permit modification, as appropriate.
   a.  The emissions unit emits and has the potential to emit no more
than 5 tons per year of any criteria or toxic air pollutant.
   b.  The emissions unit emits and has the potential to emit less than the
minimum emission rate listed in LAC 33:III.5112, Table 51.1, for each
Louisiana toxic air pollutant.
   c.  The emissions unit emits and has the potential to emit less than the
de minimis rate established pursuant to Section 112(g) of the federal Clean
Air Act for each hazardous air pollutant.
   d.  No new federally enforceable limitations or permit conditions are
necessary to ensure compliance with any applicable requirement.

  1State or federal regulations may apply.



    B.6.  Grandfathered Status. Those facilities which were under
actual construction or operation as of June 19, 1969, and granted
grandfathered status by DEQ may maintain such grandfathered
status, provided a current and accurate Emissions Inventory
Questionnaire is maintained on file with the permitting authority
and provided the owner or operator of such facility is not
required or requested to submit a permit application in
accordance with this Paragraph. Grandfathered status shall be
maintained until final action is taken by the permitting
authority on the permit application, provided such application is
submitted in a timely manner. A permit application shall be submitted in
accordance with LAC 33:III.517.A if any of the following criteria
are met or will be met by a planned change at the facility:
         a.  the facility is a major source of Louisiana toxic air
pollutants, as defined in LAC 33:III.Chapter 51;
         b.  the facility is a Part 70 source, as defined in LAC 33:III.502;
         c.  ownership of the facility has changed since grandfathered
status was granted;
         d.  emissions have been initiated or increased at the
facility, since the time grandfathered status was granted, as a
result of new construction, modification, change of process or
raw materials, or change of operating schedule; or
         e.  the facility is otherwise required to obtain a permit
based upon a determination by the permitting authority.

AQ102   §501.B.7;LAd51;LA048.04B;AQ102;LR20:1375(12/20/1994)
    B.7.  Research and Development Facilities. The permitting
authority may allow a research and development facility to be
considered as a separate source with regard to the
requirements of this Chapter, provided that the facility has a
different two-digit Standard Industrial Classification (SIC)
code from, and is not a support facility of, the source with
which it is co-located.

   C.  Scope
MM002   §501.C.1;LAd51;LA048.10H;MM002;LR33:2082(10/20/2007)
    C.1.  For each source to which this Chapter applies, the
owner or operator shall submit a timely and complete permit
application to the Office of Environmental Services as
required in accordance with the procedures delineated
herein. Permit applications shall be submitted prior to
construction, reconstruction, or modification unless
otherwise provided in this Chapter.
    C.2.  No construction, modification, or operation of a
facility which ultimately may result in an initiation increase
in emission of air contaminants as defined in LAC 33:III.111
shall commence until the permit application has been approved, an
appropriate permit fee paid (in accordance with LAC 33:III.Chapter 65
[now Chapter 2]) and a permit (certificate of approval)
has been issued by the permitting authority.
    C.3.  Notwithstanding Subsection C.2 of this Section, prior
to issuance or revision of a permit, the permitting authority may
issue authorization to construct to an owner or operator in
appropriate circumstances where there is a positive human health
or environmental benefit, provided such an authorization is not
precluded by any federally applicable requirement or by 40 CFR Part 70.
    C.4.  The owner or operator of each source to which this
Chapter applies shall have a general duty to operate under a
permit, unless an exemption to the source applies or has been
granted in accordance with this Chapter. The source shall be
operated in accordance with all terms and conditions of the
permit. Noncompliance with any term or condition of the permit
shall constitute a violation of this Chapter and shall be grounds
for enforcement action, for permit revision or termination, or
for denial of a permit renewal application.
    C.5.  The owner or operator of each source to which this
Chapter applies shall comply with any federally applicable
requirement, as defined in LAC 33:III.502, established under the
federal Clean Air Act as amended or promulgated by the
administrator pursuant to the federal Clean Air Act as amended.
    C.6.  The permitting authority shall incorporate into each
permit sufficient terms and conditions to ensure compliance with
all state and federally applicable air quality requirements and
standards at the source and such other terms and conditions as
determined by the permitting authority to be reasonable and
necessary. It is the intent of this regulation that suitable
controls be applied to new installations and relocations and in
cases where modifications are to be made or where significant
changes in emissions are anticipated.
    C.7.  The terms and conditions of the permit shall be
enforceable by the administrative authority and may be utilized
to implement and enforce all requirements and standards
incorporated therein. Any terms and conditions of the permit
issued pursuant to the State Implementation Plan or to LAC 33:III.507
are enforceable by the administrator unless specifically designated
in the permit as not being federally enforceable.
    C.8.  Each permit issued shall fulfill the requirements to
obtain both a preconstruction and an operating permit in
accordance with state and federal air quality programs. Permit
issuance, amendments, revisions, and renewals shall be issued in
accordance with the procedures established in this Chapter.
    C.9.  When a single site includes more than one process, a
single permit may be issued to include all processes at the site.
Conversely, multiple permits may be issued each of which may
address one or more processes at the site.
    C.10.  NOT IN SIP – EPA has never acted on this paragraph

AQ240   §501.C.11;LAd51;LA048.09G;AQ240;LR32:1842(10/20/2006)
    C.11. Emissions shall be calculated in accordance with
LAC 33:1II.919.C.


AQ240   §501.C.12;LAd51;LA048.09G;AQ240;LR32:1842(10/20/2006)
    C.12. Emissions estimation methods set forth in the
Compilation of Air Pollution Emission Factors (AP-42) and
other department-accepted estimation methods may be
promulgated or revised. As a result of new or revised AP-42
emission factors for sources or source categories and/or
department-accepted estimation methods, changes in
calculated emissions may occur. Changes in reported
emission levels as required by LAC 33 :III.919.B.2.a due
solely to revised AP-42 emission factors or department-
accepted estimation methods do not constitute violations of
the air permit; however, the department may evaluate
changes in emissions on a case-by-case basis, including but
not limited to, assessing compliance with other applicable
Louisiana air quality regulations.


AQ240   §501.C.13;LAd51;LA048.09G;AQ240;LR32:1842(10/20/2006)
    C.13. If the emission factors or estimation methods for
any source or source category used in preparing the Annual
Emission Statement required by LAC 33:III.918 and 919
differ from the emission factors or estimation methods used
in the current air permit such that resulting "calculated"
emissions reflect a change as defined in LAC33:III.919.B.2.a,
notification of the use of updated emission
factors or estimation methods shall be included in the Title V
Annual Certification, as specified in the affected permit. The
notification shall include the old and new emission factor or
estimation method reference source and the date, volume,
and edition (if applicable); the raw data for the reporting
year used for that source category calculation; and
applicable emission point and permit numbers that are
impacted by such change. The notification shall include any
other explanation, as well as the facility's intended time
frame to reconcile the emission limits in the applicable
permit. The department reserves the right to reopen a permit
pursuant to LAC 33:III.529.
