Is stack testing required for emissions determinations?
No. While a source may choose to conduct stack testing to determine regulated toxic air pollutant (RTAP) emissions, it is not required. Other methods such as the use of engineering calculations, published emission factors, etc. may be adequate. If you choose to conduct stack testing to determine RTAP emissions, you should send DES a description of the proposed test methods, procedures, operating parameters and proposed test date prior to conducting the test, and request DES approval.
