The State of Utah has permitted equipment for Kilgore Contracting, LLC on the portable

All equipment operating at this site must be in accordance with the current Bluffdale Asphalt

shall also be subject to Conditions II.B.7.a through II.B.7.c of this AO.

Approval is granted to relocate and operate this equipment at the new location for a period not to

This message originated from outside your organization
Hello, can you let me know how the relocated generators will be used at the Asphalt Materials' Bluffdale facility? I primarily need to determine if the generators will be subject to the hourly
limits specified for the topsoil equipment as per Condition II.B.5, or the recycle equipment hourly limits as per Condition II.B.6. I've attached the Bluffdale Approval Order for reference.

Thanks, let me know if you have any questions.
Susan Weisenberg,
