a change that in the commissioner's judgment significantly affects the ability of the system to measure or record the pollutant concentration, volumetric gas flow, or opacity.

Subp. 3.

Changes to a CEMS or COMS which do not invalidate certification.

software modifications in the automated data acquisition and handling system, where the modification is only for the purpose of generating additional or modified reports.

Subp. 4.

Notification of changes requiring recertification.
