SOURCE INFORMATION
General Description
Tesoro Logistics Operations LLC (TLO) operates a Remote Tank Farm (RTF) and Truck Loading Rack
(TLR). The TLR is located on property adjacent to and south of the Tesoro Refinery but is fenced and
monitored so that authorized access is controlled independent from the refinery. The RTF is located
approximately one (1) mile northwest of the Tesoro Refinery.

The TLR is a fuel-loading facility for the distribution of products produced by the Tesoro Salt Lake City
Refinery. The facility includes five (5) truck transport load spots, each capable of delivering gasoline, jet
fuel, and distillate products to tank trucks. Ethanol and other additives are blended in line with refined
products during transfer to trucks. Runoff from the loading bays is routed through a catch basin and then
to the oil-water separator (OWS). Oil separated from the runoff is routed from the OWS to the refinery's
slop oil system, and the water phase is routed to the refinery's oily water sewer. A crude oil unloading
facility is also operated at the TLR. Crude oil is unloaded from tank trucks and transferred directly to the
refinery - there is no storage of crude oil at the TLR.

The RTF receives crude oil via pipeline, which is stored in storage tanks before being sent to the Tesoro
Refinery crude unit. The RTF also has bidirectional pipelines from the refinery and storage tanks, which
are used to supplement gasoline and diesel storage capacity at the Tesoro Refinery. In addition, gasoline
and diesel products are distributed to transportation pipelines from the RTF.

Project Description
During the issuance of AO DAQE-AN156590010-24, a typographical error was introduced into condition

and not subject to the external floating roof requirements of these two (2) conditions. The reference will
be removed. There are no changes in emissions from this correction.

REVIEWER COMMENTS

1. Comment regarding Administrative Amendment: This is an administrative amendment to correct a typographical error that appeared in the latest AO. Conditions II.B.1.a and II.B.1.b both reference "Tank 509". This is incorrect and was not part of the actual permitting of Tank 509. Tank 509 is an internal floating roof tank and thus is not subject to the gap measurement requirements associated with external floating roof tanks. The language has been reverted back to the original wording. [Last updated January 14, 2025]
