Stack testing is not required for the emission points described in this "Collection of Air Permits" this time.

If stack testing is required by a construction permit, the owner or the owner's authorized agent shall use the test method and run time listed in the "Compliance Demonstration Table" unless another testing methodology is approved by the Department prior to testing. 

Each emissions compliance test must be approved by the Department. Unless otherwise specified by the Department, each stack test shall consist of three (3) separate runs.  The arithmetic mean of three (3) acceptable test runs shall apply for compliance, unless otherwise indicated by the Department.  

Per 567 IAC 25.1(7)"a", at the Department's request, a pretest meeting shall be held not later than fifteen (15) days before the owner or operator conducts the compliance demonstration.  A testing protocol shall be submitted to the Department no later than fifteen (15) days before the owner or operator conducts the compliance demonstration.  Representatives from the Department shall attend this meeting, along with the owner and the testing firm, if any.  It shall be the responsibility of the owner to coordinate and schedule the pretest meeting.  A representative of the Department shall be allowed to witness the test(s).  The Department shall reserve the right to impose additional, different, or more detailed testing requirements.

2. Compliance Demonstration(s) (Continued)

The owner shall be responsible for the installation and maintenance of test ports.  The unit(s) being sampled shall be operated in a normal manner at its maximum continuous output as rated by the equipment manufacturer, or the rate specified by the owner as the maximum production rate at which this unit(s) will be operated. In cases where compliance is to be demonstrated at less than the maximum continuous output as rated by the manufacturer, and it is the owner's intent to limit the capacity to that rating, the owner may submit evidence to the Department that this unit(s) has been physically altered so that capacity cannot be exceeded, or the Department may require additional testing, continuous monitoring, reports of operating levels, or any other information deemed necessary by the Department to determine whether this unit(s) is in compliance.

3.  Emission Point Characteristics

These permits are for the construction and operation of specific emission unit(s), control equipment, and emission point(s) as described in these permits and in the applications for these permits.  The permit holder, owner, and operator of the facility shall assure that the installation of the equipment listed in these permits conform to the design in the application (i.e. type, maximum rated capacity, etc.).  No person shall construct, install, reconstruct or alter any of the emission unit(s), or emission point(s), or the associated control equipment without the required amended permit(s).

Any owner or operator of the specified emission unit(s), emission point(s), or associated control equipment, including any person who becomes an owner or operator subsequent to the issuance date of the affected permit(s), is responsible for assuring that the installation, operation, and maintenance of the equipment listed in the permit(s) is in compliance with the provisions of the permit(s) and all other applicable requirements  and that adequate operation and maintenance is provided to ensure that no condition of air pollution is created.

9.  Transferability

Unless the equipment is portable, these permit(s) are not transferable from one location to another or from one piece of equipment to another.  See Condition 12.A.(2) for notification requirements for relocating portable equipment (567 IAC 22.3(3)"f").  

10.  Construction

 General Requirements:
      It is the owner's responsibility to ensure that construction conforms to the final plans and specifications as submitted.  
      
      In permit amendments, all provisions of the original permit remain in full force and effect unless they are specifically changed by the permit amendment.  If a proposed project is not timely completed, the owner or operator shall seek a permit amendment in order to revert back to the most recent previous version of the permit.  The previous, unchanged permit provisions are included in the amendment for your convenience only and are unappealable.
      
      The permit or amendment shall become void if any one of the following conditions occurs:
 the construction or implementation of the proposed project, as it affects each emission point permitted herein, is not initiated within eighteen (18) months after the permit issuance date; or
  the construction or implementation of the proposed project, as it affects each emission point permitted herein, is not completed within thirty-six (36) months after the permit issuance date; or
 the construction or implementation of the proposed project, as it affects each emission point permitted herein, is not completed within a time period specified elsewhere in the permit.

 Changes to Plans and Specifications:
The owner or operator shall amend the permit or amendment prior to startup of the equipment if:
 Any changes are made to the final plans and specifications submitted for the proposed project; or
 The permit becomes void.

Changes to the final plans and specification shall include changes to plans and specifications for permitted equipment and control equipment and the specified operation thereof.

 Amended Permits:
The owner or operator may continue to act under the provisions of the previous permit for the affected emission unit(s) and emission point, together with any previous amendment to the permit, until one of the following conditions occurs:
          The proposed project authorized by this amendment is completed as it affects the emission unit(s) and emission point permitted herein; or
          This current amendment becomes void.

11.  Excess Emissions

Per 567 IAC 24.1(1), excess emissions during a period of startup, shutdown, or cleaning of control equipment are not a violation of the emission standard if it is accomplished expeditiously and in a manner consistent with good practice for minimizing emissions except when another regulation applicable to the unit or process provides otherwise.  Cleaning of control equipment, which does not require the shutdown of process equipment, shall be limited to one (1) six-minute period per one (1) hour period.
