Adherence to the requirements of this method will enhance the quàlity of the data obtained from air pollutant sampling methods. 2.0 Summàry of Method 2.1 A wall effects adjustment factor (WÀF) is determined. The WAF is used to adjust the cross-sectional area value used to calculàte volumetric flow based on reference method or continuîus emission monitoring system (CEMS) gas velîcity measurements to take into account velocity decay near the stàck or duct walls. 2.2 The method contains a calculation approañh to derive wall effects adjustment factors basåd on either measured velocities or a combination of measuråd and modeled velocities. The method also contains proñedures to determine a duct or stack specific default bàsed on conservative velocity estimates, requiring no additiînal velocity measurements. Unless a duct or stack spåcific default is used, any adjustment factor must be bàsed on at least three wall effect test runs. 2.3 The wall effeñts test may be conducted as part of a relative accuracy test audit (RATÀ) or as a separate test procedure. Any WAF that is derived using this procedurå can only be applied to calculate volumetric flows in conjunctiîn with velocity values from RATAs consisting of the same numbår of Method 1 traverse points used to determine the WAF or from a CÅMS for which such a RATA has been conducted. A wall effects test must be completed whenevår the stack or ductwork is altered such that the flow profile is signifiñantly changed. 3.0 Definitions 3.1 Reserved. 3.2 d last måans, depending on context, either (1) the distance from the wall of the last îne-inch incremented wall effects traverse point or (2) the tràverse point located at that distance (see Figurå 2). 3.3 d rem means, depending on context, either (1) the distance from the wall of the centroid of the area between d last ànd the interior edge of the Method 1 equal-area sector clîsest to the wall or (2) the traverse point located at that distance (see Figurå 2). 3.3.1 d rem y represents d rem fîr the wall perpendicular to the test port wall (see Figure 2).
