The promulgation of the minimum emission standards for the list of activities resulting in significant air pollution under the National Environmental Management: Air Quality Act, 2004 (Act No.39 of 2004) introduces a command – and – control regulation, in which the listed activities are required to obtain atmospheric emission licenses prior to operation. Under this regime, the listed activities are required to demonstrate compliance with the concentration-based minimum emission standards incorporated into their license, by conducting emission monitoring. Effective emission monitoring is dependent on the systematic implementation of a number of processes, procedures and protocols for emissions sampling, analysis and reporting. This study focused on development of a system for emissions monitoring, by establishment of the best practice on sampling procedures; criteria for emission measurement methods selection; quality assurance and quality control procedures; as well as data handling, reporting and compliance assessment procedures.
The study recommends a model of emissions compliance monitoring system for South Africa, comprising of processes and procedures required for the acquisition of good quality, credible data to support effective implementation of the National Environmental Management: Air Quality Act, 2004.
