NuStar Energy L.P. Announces Open Season for Second Capacity Expansion of NuStar’s Permian Crude System

Shippers to Have More Capacity Available to Access Multiple End
Markets out of Permian Basin

SAN ANTONIO–(BUSINESS WIRE)–NuStar Energy L.P. (NYSE: NS) announced today the start of its Binding
Open Season involving a second capacity expansion of NuStar Permian
Transportation and Storage LLC’s Permian Crude System.

NuStar Permian Crude System Expansion No. Two

With crude oil throughput volumes to certain destinations on NuStar’s
Permian Crude System approaching the system’s capacity, the NuStar
Permian Crude System Expansion No. Two will provide shippers with
additional transportation capacity that is capable of reaching multiple
downstream markets through interconnects at Colorado City, Texas. The
NuStar Permian Crude System Expansion No. Two is currently expected to
consist of three phased-in expansion projects, including: Big Spring
South Inlet; Colorado City Mainline Expansion; and County Line Loop.
Once completed, these projects are expected to provide approximately
70,000 barrels per day of additional capacity on the Permian Crude
System, of which 90 percent of such additional capacity will be
available for volume commitments during the Open Season.

Under the NuStar Permian Crude System Expansion No. Two Open Season,
potential shippers will have the opportunity to make volume commitments
and sign a Transportation Services Agreement (TSA) from designated
origin point segments to NuStar’s Colorado City, Texas Terminal at
tiered-volume committed rates. Subject to the limitations set forth in
the TSA, shippers that execute a TSA during the Open Season will also
have the option to elect firm transportation rights on NuStar’s Permian
Crude System during periods of prorationing for those movements for
which shippers have made volume commitments.
