Oregon Administrative Rules › Chapter 340 - DEPARTMENT OF ENVIRONMENTAL QUALITY › Division 212 - STATIONARY SOURCE TESTING AND MONITORING › Section 340-212-0250 - Operation of Approved Monitoring

Current through Register Vol. 63, No. 7, July 1, 2024
(1) Commencement of operation. The owner or
			 operator must conduct the monitoring required under OAR
			 340-212-0200  through
			 340-212-0280  upon issuance of an Oregon Title V Operating Permit that includes such
			 monitoring, or by any later date specified in the permit pursuant to
			 340-212-0240(4).
(2) Proper maintenance. The owner
			 or operator must at all times maintain the monitoring equipment, including but
			 not limited to, maintaining necessary parts for routine repairs of the
			 monitoring equipment.
(3)
			 Continued operation. Except for monitoring malfunctions, associated repairs,
			 and required quality assurance or control activities including, as applicable,
			 calibration checks and required zero and span adjustments, the owner or
			 operator must conduct all monitoring in continuous operation, or must collect
			 data at all required intervals, at all times that the regulated
			 pollutant-specific emissions unit is operating. Data recorded during monitoring
			 malfunctions, associated repairs, and required quality assurance or control
			 activities cannot be used for purposes of OAR
			 340-212-0200  through
			 340-212-0280,
			 including data averages and calculations, or fulfilling a minimum data
			 availability requirement, if applicable. The owner or operator must use all the
			 data collected during all other periods in assessing the operation of the
			 control device and associated control system. A monitoring malfunction is any
			 sudden, infrequent, not reasonably preventable failure of the monitoring to
			 provide valid data. Monitoring failures that are caused in part by poor
			 maintenance or careless operation are not malfunctions.
(4) Response to excursions or exceedances:
(a) Upon detecting an excursion or
			 exceedance, the owner or operator must restore operation of the regulated
			 pollutant-specific emissions unit, including the control device and associated
			 capture system, to its normal or usual manner of operation as expeditiously as
			 practicable in accordance with good air pollution control practices for
			 minimizing emissions. The response must include minimizing the period of any
			 startup, shutdown or malfunction and taking any necessary corrective actions to
			 restore normal operation and prevent the likely recurrence of the cause of an
			 excursion or exceedance, other than those caused by excused startup or shutdown
			 conditions. Such actions may include initial inspection and evaluation,
			 recording that operations returned to normal without operator action, such as
			 through response by a computerized distribution control system, or any
			 necessary follow-up actions to return operation to within the indicator range,
			 designated condition, or below the applicable emission limitation or standard,
			 as applicable;
(b) Determination
			 of whether the owner or operator has used acceptable procedures in response to
			 an excursion or exceedance will be based on information available, which may
			 include but is not limited to, monitoring results, review of operation and
			 maintenance procedures and records, and inspection of the control device,
			 associated capture system, and the process;
(c) Documentation of need for improved
			 monitoring. After DEQ approves the monitoring plans under OAR
			 340-212-0200  through
			 340-212-0280,
			 if the owner or operator identifies a failure to achieve compliance with an
			 emission limitation or standard for which the approved monitoring did not
			 indicate an excursion or exceedance while providing valid data, or if the
			 results of compliance or performance testing document a need to modify the
			 existing indicator ranges or designated conditions, the owner or operator must
			 promptly notify DEQ and, if necessary, submit a proposed modification to the
			 Oregon Title V Operating Permit to address the necessary monitoring changes.
			 Such a modification may include, but is not limited to, reestablishing
			 indicator ranges or designated conditions, modifying the frequency of
			 conducting monitoring and collecting data, or the monitoring of additional
			 parameters.
