Anatomy Of A Retail Site Tank Installation
Arco AM/PM jobsite, Thorp WA, July 2008

              
                                            Ready To Go
        This site along I-90 in central Washington is utilizing Containment Solutions
        doublewall fiberglass tanks.  Tank capacities:  30,000, 22,000 and 20,000
        gallons.


                                                                   Prepping The Hole
Employees of the installing contractor work on preparation of the final destination for the tanks. Many sites
have water issues that must be dealt with before tank installation can proceed.

                                 
                                                  Placement And Anchoring
                            Installers examine a concrete anchor adjacent to one of the fiberglass tanks.
                            Straps over the top of the tank will tie to the anchor on either side of the tank
                            to keep the tank buried in an area of a high water table.

                                A view of the site with the tanks partially buried. Still to come: Bonding
                                of sumps to  the round fiberglass  rings atop the  tanks,  installation  of
                                tank-related accessories, and piping runs from tanks to the dispensers.

Your source for above- and underground tanks

Discover that there is such a thing as The Mascott Difference.
In addition to providing all of the 'bells and whistles' for most any fueling application, Mascott Equipment works with numerous
tank fabricators providing UL approved fuel storage for private
consumer, commercial and retail situations.

UL codes addressed by our suppliers:


UNDERGROUND TANKS:
•UL-58 — For horizontal steel atmospheric tanks, intended for underground storage of flammable and combustible liquids.
This code covers singlewall tanks and secondary-contained
tanks, both single compartment and multiple compartment.
These tanks are intended for use as permitted by the Uniform
Fire Code published by the International Fire Code Institute,
NFPA 30 (the Flammable and Combustible Liquids Code),
NFPA 30A (the Automotive and Marine Service Station Code),
NFPA 31 (Standard for the Installation of Oil-Burning
Equipment) and NFPA 37 (Standard for the Installation and
Use of Stationary Combustion Engines and Gas Turbines).


•UL-1316— For glass-fiber-reinforced plastic (FRP)
atmospheric single and doublewall tanks, covering
underground storage of petroleum-based flammable and combustible liquids. Such labeled tanks are intended for
installation and use in accordance with NFPA 30 (the
Flammable and Combustible Liquids Code) and NFPA 31 (Standard for the Installation of Oil-Burning Equipment).


•UL-1746 — For atmospherically-vented tanks with pre-
engineered corrosion protection systems (factory-installed
galvanic-type cathodic protection, factory-assembled
composite systems, factory-assembled jacket systems and
factory-assembled coated systems). Such systems are
intended to be completely installed at the manufacturing
facility on carbon steel underground tanks.


ABOVEGROUND TANKS:
•UL-80 — Covers steel primary, steel secondary and
steel dike-type atmospherically vented tanks from 60 to
660 gallons. Intended primarily for the storage and the
supply of heating fuels for oil burning equipment or
alternately for the storage of diesel fuels for compression
ignition engines and motor oils (new and used) for
automotive service stations in aboveground applications.


•UL-142 — For steel primary, secondary and diked-type
atmospherically-vented storage atanks intended for
non-corrosive, stable flammable and combustible liquids
that have a specific gravity not exceeding 1.0 in
aboveground applications.


•UL-2080 — Regulations covering shop fabricated,
atmospherically-vented Fire-Resistant tanks intended for
storage of stable flammable or cumbustible liquids that
have a specific gravity not greater than 1.0 and that are
compatible with the material and construction of the tank.


•UL-2085 —  Regulations covering shop fabricated,
atmospherically-vented Fire-Protected tanks intended for
storage of stable flammable or cumbustible liquids that
have a specific gravity not greater than 1.0 and that are
compatible with the material and construction of the tank.


•UL-2244 — For factory fabricated, pre-engineered above-
ground atmospheric-vented tank systems intended for
dispensing flammable or combustible liquids, such as
gasoline or diesel fuel, into motor vehicles, aircraft or
generators.

Among the tank manufacturers Mascott Equipment
enjoys a working relationship with:

•Brown-Minneapolis Tank (BMT): Aboveground
          steel tanks, field-erected AWWA and API
          tanks.
•Containment Solutions: FRP underground tanks,
          oil/water separators
•Greer Steel: Steel and aluminum tanks.
•Modern Welding: Aboveground and under-
          ground tanks.
