Subject: Application for Specific Use Permit & Site Plan Review
NuStar Southlake Terminal - New Tank 1M-2 Transmix
Dear Mr. Rothenberger:
NuStar Logistics, L.P. (NuStar) respectfully submits the enclosed permit
application package for Special Use Permit and associated Site Plan Review
related to the proposed construction of a new Transmix tank at NuStar’s existing
Southlake Terminal at 1700 Mustang Court, Grapevine, TX 76092.
NuStar proposes to install a 1250-barrel carbon steel transmix (refined product
mixture) tank and appurtenances at our existing Southlake Terminal to support the
receipt of the product via pipeline before loading onto trucks. This 15-foot
diameter by 40-foot tall vertical tank would be constructed within the existing
secondary containment area and would not impact the floodplain. This transmix
tank is necessary to support existing facility operations and contractual
obligations to customers regarding product movement. NuStar is not proposing to
expand the facility or otherwise change the existing use of the facility.
Through discussions with the City of Southlake (the City), NuStar understands
that historical land use documents were/are in place that would generally facilitate
this proposed accessory use of our existing facility, which may include Specific
Use Permit(s) for Petroleum Operations, Special Exception Use, and/or Site Plan
Review(s), but cannot be located by either party despite extensive searches.
Therefore, NuStar submits the enclosed applications for the City’s processing and
consideration of the proposed work to support our continued safe operations at
our Southlake Terminal.
To assist with this review, we have enclosed the following documents:
• Special Use Permit Application
• Site Plan Review Application
• Project Description & Details
• Plot Plan (SLPL-SOUT-21-101)
• Piping & Instrumentation Diagram (SLT TMIX Tank PIDs 4-6_JSMU)
