Q165. What is an industry standard practice, and when can one be used? How should I report an industry standard practice? Is "third party verification" or "delivery record" an industry standard practice?

A165. A delivery record itself is a record and not a quantity determination method or standard practice. The appropriate method or practice followed to determine the quantity cited in a delivery record must be reported. Third party verification is also not a quantity determination method or standard practice. The appropriate method or practice followed by the third party to determine quantity must be reported.A165.  An industry standard practice is an approach to determine quantity that achieves a precision which most members of your industry would consider reasonable for the particular product, conditions, and circumstances. You may only use an appropriate industry standard practice to determine quantity if no standard method published by a consensus-based organization exists or would be appropriate to measure the particular product under the particular conditions and circumstances. When you report the industry standard practice to EPA in your annual report, you must describe the equipment and procedures such that EPA can understand how you obtained your quantity measurements, and you must document the method in your monitoring plan.
