VOC/NOx Screening for Ozone Standards

***
The Scheffe memo has been used as a screening method to demonstrate compliance with ozone standards based on a facility's VOC and NOx PTEs. The first link below is a poor-quality scanned version of the memo with "draft" stamped on several pages. The second link is from a Nevada web site; it's cleaner and doesn't have the draft markings, but it cautions that it's a recreation of the original and they don't guarantee its accuracy.

Cleaned version on Nevada web site

Here's a table and chart based on the Scheffe method that was used for permitting a previous incarnation of the Montana Advanced Biofuels project (stored in project folder ACT203382).
