Source Sampling

Source sampling activities include Emissions Testing, Relative Accuracy Test Audits (RATAs), Cylinder Gas Audits (CGAs), Opacity Audits, and Leak Detection Audits (LDA). The Emissions Measurement Section (EMS) at ADEM ensures these tests are conducted in accordance with state and federal regulations by reviewing test plans, observing emissions tests, and evaluating the test reports. In addition, the EMS has a test team that performs stack tests around the state.
