This document is intended to be a resource for understanding and performing economic analyses by OAQPS economists. This document should not be interpreted as guidance that will be followed exactly by OAQPS in its analyses. Each analysis performed by OAQPS presents unique features, so this guidance is only advisory in nature. This document will need to be revised to reflect changes in EPA's approach to implementing statutory or administrative requirements and to clarify and update text if the document is to continue to be a helpful resource.
