The Template What-If / Checklist worksheet used to guide PHA Studies has been modified.
- The Identification and Review of Past Incidents section has been renumbered with some new questions concerning the performance of the Incident Investigation element added before the example / industry What-If incident questions.
- We’ve added a new 57-question Revalidation Considerations Checklist to the current list of What-If questions. This new section is to be used as an additional check on PHA revalidations.
These changes are available immediately to anyone using the Google Shared Drive.
Note: These additions are partially based on an EPA-provided example of typical questions asked during a PHA revalidation. It has always been our practice to FULLY revalidate the PHA by reviewing all the previous answers; however, during a revalidation, this new section should help highlight areas of the existing PHA study that demand extra attention.
