CHAPTER 101GENERAL AIR QUALITY RULES
SUBCHAPTER FEMISSIONS EVENTS AND SCHEDULED MAINTENANCE, STARTUP, AND SHUTDOWN ACTIVITIES
DIVISION 2MAINTENANCE, STARTUP, AND SHUTDOWN ACTIVITIES
RULE §101.211Scheduled Maintenance, Startup, and Shutdown Reporting and Recordkeeping Requirements

    (F) the date and time of the scheduled maintenance, startup, or shutdown activity, and the duration of any maintenance activity;

    (G) the duration of the emissions from the scheduled maintenance, startup, or shutdown activity;

    (H) the compound descriptive type of the individually listed compounds or mixtures of air contaminants, in the definition of RQ in §101.1 of this title, that are known through common process knowledge, past engineering analysis, except for boilers or combustion turbines referenced in the definition of RQ in §101.1 of this title and that were unauthorized. Compounds or mixtures of air contaminants, that have an RQ greater than or equal to 100 pounds and the amount released is less than ten pounds in a 24-hour period, are not required to be specifically listed in the record instead these compounds or mixtures of air contaminants may be identified together as "other;" and

    (I) the estimated total quantities and the authorized emissions limits for those compounds or mixtures described in subparagraph (H) of this paragraph. Good engineering practice and methods must be used to provide reasonably accurate representations for emissions and opacity. Estimated emissions from compounds or mixtures of air contaminants that are identified as "other" under subparagraph (H) of this paragraph are not required for each individual compound or mixture of air contaminants, however, a total estimate of emissions must be provided for the category identified as "other."

(c) For any scheduled maintenance, startup, or shutdown activity for which an initial notification was submitted under subsection (a) of this section, which does not provide all the information required in subsection (b) of this section or if the information has changed from the prior notification, the owner or operator of the regulated entity shall submit a final record as required by subsection (b) of this section to the commission office for the region in which the regulated entity is located and to appropriate local air pollution agencies with jurisdiction no later than two weeks after the end of the scheduled activity. If the owner or operator does not submit a record under this subsection, the information provided under subsection (a) of this section will be the final record of the scheduled activity.

(d) The owner or operator of a boiler or combustion turbine as defined in §101.1 of this title fueled by natural gas, coal, lignite, wood, or fuel oil containing hazardous air pollutants at a concentration of less than 0.02% by weight, that is equipped with a continuous emission monitoring system that completes a minimum of one operating cycle (sampling, analyzing, and data recording) for each successive 15-minute interval, and is required to submit excess emissions reports by other state or federal rules, is exempt from creating, maintaining, and submitting final records of scheduled maintenance, startup, and shutdown activities with unauthorized emissions under subsections (b) and (c) of this section, if the notice submitted under subsection (a) of this section contains the information required under subsection (b) of this section.

(e) The executive director may specify the amount, time, and duration of emissions that will be allowed during the scheduled maintenance, startup, or shutdown activity. The owner or operator of any source subject to the provisions of this section shall submit a technical plan for any scheduled maintenance, startup, or shutdown activity when requested by the executive director with a copy to the appropriate local air pollution agencies with jurisdiction. The plan must contain a detailed explanation of the means by which emissions will be minimized during the scheduled maintenance, startup, or shutdown activity. For those emissions that must be released into the atmosphere, the plan must include the reasons such emissions cannot be reduced further.

(f) For annual scheduled maintenance, startup, and shutdown activity reporting on or before March 31, of each calendar year, beginning in calendar year 2007, or as directed by the executive director, each owner or operator of a regulated entity site, as defined in §101.1 of this title that is subject to reporting under §101.10 of this title (relating to Emissions Inventory Requirements), that experienced at least one scheduled maintenance, startup, and shutdown activity during the calendar year must report to the executive director, and all appropriate local air pollution control agencies with jurisdiction:

  (1) the number of reportable and non-reportable scheduled maintenance, startup, and shutdown activities experienced at the regulated entity; and

  (2) the estimated total quantities for all compounds or mixtures, by compound or mixture, of air contaminants, in the definition of RQ in §101.1 of this title that, by facility, emitted during scheduled maintenance, startup, and shutdown activities at the regulated entity. Compounds or mixtures of air contaminants, that have an RQ greater than or equal to 100 pounds and the amount released is less than one pound in a 24-hour period, are not required to be included in the report. Good engineering practice and methods must be used to provide reasonably accurate representations for emissions and opacity. This paragraph does not apply to boilers and combustion turbines referenced in the definition of RQ in §101.1 of this title, that must report only the estimated opacities during emissions events and duration of unauthorized opacity; and

  (3) owners and operators of regulated entities that are subject to reporting under §101.10 of this title shall provide the information required by this subsection as part of their reporting under §101.10 of this title.
