CEMS installation procedure

The figure below (Figure 2.1 of the Guidelines) summarizes the entire procedure required to install CEMS. Plant operators shall refer to the CEMS equipment and consultants registered with the Department of Environment Malaysia (DOE), select the appropriate one, and apply the detailed information to the DOE. After that, the functional test of CEMS (calibration and variability) shall be conducted. If there are no problems with the test results, the data shall be connected to the DOE server to check the status of the transmission of the data measured by the CEMS. Finally, a Quality Assurance Plan (QAP) that stipulates the maintenance and performance evaluation of the CEMS shall be prepared and approved by the DOE.
