Thanks for this wonderful summary.

I am specifically interested in what you mention about appropriate accounting for secondary (as it pertains to EPDs anyways) impacts, like leaks, during the extraction process. How do we know if the EPDs are accounting for this appropriately?

Maybe @cheryl.smith can chime in, since that is her realm.
