The D7520-13 was arbitrarily limited to stacks less than 7 diameter on its original publication because an EPA Method 301 comparison of DCOTs to EPA Method 9 (human readers) had not been performed. This comparison has now been performed. Thus the objective of this Work Item is to remove the 7 diameter limit, and align D7520-13 with its EPA published peer Alternative Method 082.
