Current through Register Vol. 63, No. 7, July 1, 2024
(1)
			 General criteria. To provide a reasonable assurance of compliance with emission
			 limitations or standards for the anticipated range of operations at a regulated
			 pollutant-specific emissions unit, monitoring under OAR
			 340-212-0200  through
			 340-212-0280  must meet the following general criteria:
(a)
			 The owner or operator must design the monitoring to obtain data for one or more
			 indicators of emission control performance for the control device, any
			 associated capture system and, if necessary to satisfy subsection (1)(b),
			 processes at a regulated pollutant-specific emissions unit. Indicators of
			 performance may include, but are not limited to, direct or predicted emissions,
			 including visible emissions or opacity, process and control device parameters
			 that affect control device and capture system efficiency or emission rates, or
			 recorded findings of inspection and maintenance activities conducted by the
			 owner or operator;
(b) The owner
			 or operator must establish an appropriate range or designated condition for the
			 selected indicator such that operation within the ranges provides a reasonable
			 assurance of ongoing compliance with emission limitations or standards for the
			 anticipated range of operating conditions. Such range or condition must reflect
			 the proper operation and maintenance of the control device and associated
			 capture system, in accordance with applicable design properties, for minimizing
			 emissions over the anticipated range of operating conditions at least to the
			 level required to achieve compliance with the applicable requirements. The
			 reasonable assurance of compliance will be assessed by maintaining performance
			 within the indicator range or designated condition. The ranges must be
			 established in accordance with the design and performance requirements in this
			 rule and documented in accordance with the requirements in OAR
			 340-212-0220.
			 If necessary to assure that the control device and associated capture system
			 can satisfy this criterion, the owner or operator must monitor appropriate
			 process operational parameters, such as total throughput where necessary to
			 stay within the rated capacity for a control device. In addition, unless
			 specifically stated otherwise by an applicable requirement, the owner or
			 operator must monitor indicators to detect any bypass of the control device or
			 capture system to the atmosphere, if such bypass can occur based on the design
			 of the regulated pollutant-specific emissions unit;
(c) The design of indicator ranges or
			 designated conditions may be:
(A) Based on a
			 single maximum or minimum value if appropriate, e.g., maintaining condenser
			 temperatures a certain number of degrees below the condensation temperature of
			 the applicable compound being processed, or at multiple levels that are
			 relevant to distinctly different operating conditions, e.g., high versus low
			 load levels;
(B) Expressed as a
			 function of process variables, e.g., an indicator range expressed as minimum to
			 maximum pressure drop across a venturi throat in a particulate control
			 scrubber;
(C) Expressed as
			 maintaining the applicable parameter in a particular operational status or
			 designated condition, e.g., position of a damper controlling gas flow to the
			 atmosphere through a by-pass duct;
(D) Established as interdependent between
			 more than one indicator.
