Abstract

On October 5, 2006, Holly Refining and Marketing Company submitted a Notice of Intent for several 

modernization changes at their refinery in Davis County. As part of those changes several storage 

tanks which had been covered under DAQE-AN0123021-05 have been incorporated within the 

approval order covering those changes (DAQE-AN0123023-07). The purpose of this approval order 

change is to remove the duplicate tanks so that only one approval order governs the operation of those 

tanks. No physical or operational changes will take place. No public comment period is required for 

this administrative change.

The project has been evaluated and found to be consistent with the requirements of the Utah 

Administrative Code Rule 307 (UAC R307). No public comment period is required for this 

administrative change. This air quality Approval Order (AO) authorizes the project with the following 

conditions, and failure to comply with any of the conditions may constitute a violation of this order.

General Conditions:
