Sec. 63.7120  How do I monitor and collect data to demonstrate continuous 

compliance?



    (a) You must monitor and collect data according to this section.

    (b) Except for monitor malfunctions, associated repairs, required 

quality assurance or control activities (including, as applicable, 

calibration checks and required zero adjustments), and except for PSH 

operations subject to monthly VE testing, you must monitor continuously 

(or collect data at all required intervals) at all times that the 

emission unit is operating.

    (c) Data recorded during the conditions described in paragraphs 

(c)(1) through (3) of this section may not be used either in data 

averages or calculations of emission or operating limits; or in 

fulfilling a minimum data availability requirement. You must use all the 

data collected during all other periods in assessing the operation of 

the control device and associated control system.

    (1) Monitoring system breakdowns, repairs, preventive maintenance, 

calibration checks, and zero (low-level) and high-level adjustments;

    (2) Periods of non-operation of the process unit (or portion 

thereof), resulting in cessation of the emissions to which the 

monitoring applies; and

    (3) Start-ups, shutdowns, and malfunctions.
