SIP - IDAHO - 58.01.01.133
SECTION 58.01.01.133. STARTUP, SHUTDOWN AND SCHEDULED MAINTENANCE REQUIREMENTS
The requirements in Subsection 133.01 shall apply in all cases where startup, shutdown, or scheduled maintenance of any equipment or emissions unit is expected to result or results in an excess emissions event. The owner or operator of the facility or emissions unit generating the excess emissions shall demonstrate compliance with all of the requirements of Subsection 133.01, as well as the development and implementation of procedures pursuant to Subsections 133.02 and 133.03 as a prerequisite to any consideration under Subsection 131.02. (4-5-00)
01. General Provisions. The following shall pertain to all startup, shutdown, and scheduled maintenance activities expected to result or resulting in excess emissions: (4-5-00)
a. No scheduled startup, shutdown, or maintenance resulting in excess emissions shall occur during any period in which an Atmospheric Stagnation Advisory and/or a Wood Stove Curtailment Advisory has been declared by the Department within an area designated by the Department as a PM-10 nonattainment area, unless the permittee demonstrates that such is reasonably necessary to facility operations and cannot be reasonably avoided and the Department approves such activity in advance, to the extent advance approval by the Department is feasible. This prohibition on scheduled startup, shutdown or maintenance activities during Advisories does not apply to situations where shutdown is necessitated by urgent situations, such as imminent equipment failure, power curtailment, worker safety concerns or similar situations. (3-20-97)
b. The owner or operator of a source of excess emissions shall notify the Department of any startup, shutdown, or scheduled maintenance event that is expected to cause an excess emissions event. Such notification shall identify the time of the excess emissions, specific location, equipment involved, and type of excess emissions event (i.e. startup, shutdown, or scheduled maintenance). The notification shall be given as soon as reasonably possible, but no later than two (2) hours prior to the start of the excess emissions event unless the owner or operator demonstrates to the Department’s satisfaction that a shorter advanced notice was necessary. The Department may prohibit or postpone any scheduled startup, shutdown, or maintenance activity upon consideration of the factors listed in Subsection 134.03. (4-5-00)
c. The owner or operator of a source of excess emissions shall report and record the information required pursuant to Sections 135 and 136 for each excess emissions event due to startup, shutdown, or scheduled maintenance. (3-20-97)
d. The owner or operator of a source of excess emissions must make the maximum reasonable effort, including off-shift labor where practicable to accomplish maintenance during periods of nonoperation of any related source operations or equipment. (4-5-00)
02. Excess Emissions Procedures. For all equipment or emissions unit from which excess emissions may occur during startup, shutdown, or scheduled maintenance, the facility owner or operator shall prepare, implement and file with the Department specific procedures which will be used to minimize excess emissions during such events. Specific information for each of the types of excess emissions events (i.e. startup, shutdown and scheduled maintenance) shall be established or documented for each piece of equipment or emissions unit and shall include all of the following (which may be based upon the facility owner or operator’s knowledge of the process or emissions where measured data is unavailable): (4-5-00)
a. Identification of the specific equipment or emissions unit and the type of event anticipated. (4-5-00)
b. Identification of the specific regulated air pollutants likely to be emitted in excess of applicable emission standards during the startup, shutdown, or scheduled maintenance period. (4-5-00)
c. The estimated amount of excess emissions expected to be released during each event. (3-20-97)
d. The expected duration of each excess emissions event. (3-20-97)
e. An explanation of why the excess emissions are reasonably unavoidable for each of the types of excess emissions events (i.e. startup, shutdown, and scheduled maintenance). (3-20-97)
f. Specification of the frequency at which each of the types of excess emissions events (i.e. startup, shutdown, and scheduled maintenance) are expected to occur. (3-20-97)
g. For scheduled maintenance, the owner or operator shall also document detailed explanations of: (4-5-00)
i. Why the maintenance is needed. (3-20-97)
ii. Why it is impractical to reduce or cease operation of the equipment or emissions unit during the scheduled maintenance period. (4-5-00)
iii. Why the excess emissions are not reasonably avoidable through better scheduling of the maintenance or through better operation and maintenance practices. (3-20-97)
iv. Why, where applicable, it is necessary to by-pass, take off line, or operate equipment or emissions unit at reduced efficiency while the maintenance is being performed. (4-5-00)
h. Justification to explain why the piece of equipment or emissions unit cannot be modified or redesigned to eliminate or reduce the excess emissions which occur during startup, shutdown, and scheduled maintenance. (4-5-00)
i. Detailed specification of the procedures to be followed by the owner or operator which will minimize excess emissions at all times during startup, shutdown, and scheduled maintenance. These procedures may include such measures as preheating or otherwise conditioning the emissions unit prior to its use or the application of auxiliary equipment or emissions unit to reduce the excess emissions. (4-5-00)
03. Amendments to Procedures. The owner or operator shall amend, and the Department may require amendments to, the procedures established pursuant to Section 133 from time to time and as deemed reasonably necessary to ensure that the procedures are and remain consistent with good pollution control practices. (4-5-00)
04. Filing Of Excess Emissions Procedures. (4-5-00)
a. Unless otherwise required by the Department, the failure to prepare or file procedures pursuant to Subsection 133.02 shall not be a violation of these Rules in and of itself. (4-5-00)
b. To the extent procedures or plans for excess emissions resulting from startup, shutdown, or scheduled maintenance are required to be or are otherwise submitted to the Department with any permit application, such submission, if deemed adequate by the Department, shall fulfill the requirement under this Section to file plans and procedures with the Department.
