RE: APPLICATION FOR PLANNING AND BUILDING APPROVAL
FOR AN ABOVEGROUND DIESEL FUEL STORAGE TANK.
LOCATION - RAZ TRANSPORTATION CO.
1.1655 S.W. PACIFIC HI WAY
TIGARD, OR.
DEAR MARK;
AS PER OUR PAST CONVERSATION REGARDING THE ABOVE, I AM NOW
• SUBMITTING A REQUEST FOR YOUR APPROVAL TO PROCEED WITH THIS
PROJECT.
AS WE DISCUSSED, THE PROPERTY IN QUESTION IS ZONED A GENERAL
COMMERCIAL DISTRICT, C -G, AS PER CHAPTER 18.62 OF THE TIGARD
MUNICIPAL CODE.
LOOKING AT THE TIGARD MUNICIPAL CODE, CHAPTER 18.104 - FUEL TANK
INSTALLATIONS, WE REQUEST THE FOLLOWING:
01 - THE CODE STATES THAT FLAMMABLE LIQUIDS (CLASS I) - GASOLINE -
MAY ONLY BE STORED IN INDUSTRIAL ZONES.
AS STATED: THE PURPOSE OF THESE REGULATIONS IS TO GUIDE THE
INSTALLATION OF STATIONARY FUEL TANKS WITHIN THE CITY LIMITS IN
RESIDENTIAL, COMMERCIAL AND INDUSTRIAL ZONES. THIS LEAVES US
TO BELIEVE THAT THE CODE WOULD ALLOW DIESEL FUEL TO BE SIORI'.I.D
WITHIN THIS ZONE, AS AN ACCESSORY USE TO THE PROPERTY. SOLELY
USED FOR THE PURPOSE OF SUPPORTING THE FUNCTIONS OF THE
PROPERTY USER. THIS WOULD NOT BE USED FOR ANY RETAIL
FUNCTIONS. DIESEL FUEL IS A CLASS 11 OR Ill COMBUSTIBLE LIQUID.
N.W. Distributor For Enviro -Care Used Oil Burner Systems
02 - THE ENTIRE PROPERTY IS FENCED AND SCREENED WITH
LANDSCAPING - TREES, SHRUBS, WOOD SOLID FENCING, BUILDINGS,
AND ECT. TO THE ADJOINING PROPERTIES AND STREETS.
03 - THE ENTIRE PERMIT PROCESS WILL BE FOLLOWED THROUGHOUT THIS
PROJECT.
•
04 - WE HAVE ALSO SUBMITTED THIS PROJECT TO THE T.V.F.R. FIRE
MARSHALS OFFICE FOR THEIR APPROVAL. WE DO NOT FORESEE ANY
PROBLEMS WITHIN THIS PROCESS, AS EVERYTHING THAT WE ARE
SUBMITTING/INSTALLING, MEETS AND /OR EXCEEDS THEIR NORMAL
REQUIREMENTS.
WE WILL BE FOLLOWING THE UFC `94 (AS STATE REVISED - YELLOW
PAGES). WITHIN THAT WE WILL FOLLOW ARTICLE 79 AND APPX II -F.
05 - WE WILL BE FOLLOWING THE LOCAL ELECTRICAL REQUIREMENTS,
WITH A STATE LICENSED ELECTRICIAN, PERMITS, AND INSPECTIONS.
06 - UPON YOUR APPROVAL WE WILL THEN SUBMIT THIS PACKAGE TO
THE CITY OF TIGARD'S BUILDING DEPARTMENT, FOR THEIR APPROVAL.
07 - THIS SYSTEM IS WITHIN LINE WITH THE E.P.A.'S TITLE 40 SPCC
PLAN REQUIREMENTS, ESTABLISHED IN MAY `92.
•
08 - WE ASSISTED THE CITY AND THE FIRE DIST. TO HELP WRITE THE
EXISTING CITY OF TIGARD CODES, ALLOWING THE USE OF ABOVE
GROUND FUEL TANKS. AT THAT TIME WE WERE WORKING UNDER THE
UFC `91 CODES, AS REVISED BY THE STATE FIRE MARSHALS OFFICE.
FOR THE PAST 20 YEARS I HAVE DONATED MY TIME TO THE STATE AND
LOCAL FIRE DEPARTMENTS, IN AIDING THEM TO UNDERSTAND FUELS
AND FUEL SYSTEMS. I HAVE SERVED FOR MANY YEARS ON THE STATE
FIRE MARSHAL OFFICE'S CODE COMMITTEE, FOR FUEL SYSTEMS.
THE 1991 UFC CODE HELD THAT THE USE OF ABOVE GROUND TANKS
SHOULD BE LIMITED TO SIX THOUSAND GALLONS, TIMES THREE TANKS,
FOR A TOTAL OF 18,000 GALLONS. HOWEVER, THE STATE REVISED CODES
ALLOWED FOR CLASS II AND III COMBUSTIBLE LIQUIDS, WITH THE
APPROVAL OF THE FIRE CHIEF AND JURISDICTION, TO BE RAISED IN
CAPACITY TO ANY SIZE THAT WAS REQUESTED AND APPROVED BY THE
LOCAL CHIEF. WE HAVE INSTALLED HUNDREDS OF 15,000 TO 30,000
GALLON FUEL TANKS, THROUGHOUT THE NORTHWEST, WITH FULL
APPROVALS. THE THREE SIX THOUSAND GALLON BASIC STORAGE TANKS
2
•
USE WAS ORIGINALLY DESIGNED FOR THE USE IN RETAIL, OPEN TO TI -IF
PUBLIC, SERVICE STATIONS. THESE TANKS WOULD OF STORED MOSTLY
GASOLINE.
AS WE WERE BUILDING THE 1994•UFC, WE LOOKED AT WHAT REALLY WAS
NEEDED AND HAPPENING, WITHIN A SAFE PERIMETER TO THE
PRESERVATION OF LIFE, PROPERTY, AND THE ENVIRONMENT. WE WERE
LOOKING AT THE SIZE OF A NORMAL LOAD OF FUEL THAT WAS COMING
INTO THE STORAGE SYSTEMS. THAT AVERAGED 10,000 TO 12,000 GALLONS
OF FUEL, ON TODAY'S MODERN TANKERS. IT WAS OUR BELIEF THAT IT
WAS MUCH SAFER TO STORE THE LARGER AMOUNT OF FUEL IN ONE
TANK, SO AS TO NOT CAUSE THE DELIVERY DRIVER TO RUN THE
INCOMING FUEL UP AGAINST THE 90% LIMITING VALVE, IN AT LEAST TWO
IF NOT THREE OF THE TANKS. THIS IN TIME WOULD CAUSE AT LEAST ONE
OF THE LIMITING VALVES TO FAIL, AND WOULD ALLOW THE FUEL TO
THEN JUST RUN OVER THE TOP OF THE TANK, AND TO WHERE EVER THAT
MIGHT TAKE IT. THIS WAS DEEMED TO BE AN UNSAFE PRACTICE, AND WE
CHANGED IT. THE `94 UFC RAISED THE STORAGE LIMIT TO 10,000
GALLONS, AND UP TO 40,000 COMBINED STORAGE. THIS AGAIN WAS
INTENDED TO LIMIT THE RETAIL SERVICE STATION SIZE OF STORAGE.
THE COMMERCIAL, INDUSTRIAL USERS WERE AGAIN LEFT UP TO THE
LOCAL CHIEF AND JURISDICTION. WITHIN THE T.V.F.R. AREA,
THEY HAVE ALLOWED UP TO A 30,000 GALLON DIESEL, SINGLE
COMPARTMENT TANK, WITH OTHER TANKS, WITHIN THE SAME
FUELING AREA, TO BE INSTALLED.
ANOTHER DECIDING PART OF THIS DECISION, TO ALLOW THE LARGER
TANKS, WAS TO ONLY HAVE THE FOUR SIDES OF ONE TANK TO COOL,
IN PLACE OF THE SIXTEEN SIDES OF THE FOUR TANKS, IN THE EVENT OF
A FIRE THAT MIGHT ALSO INVOLVE THE TANKS. THE LARGER FUEL TANK
ACTS AS AN INSULATING FACTOR TO THE STORED FUEL.
MY PAST EXPERIENCE INCLUDES BUILDING AND MAINTAINING BULK
PLANTS AND SERVICE STATIONS, WITH THIRTY FIVE YEARS OF IT BEING
WITH CHEVRON USA. OVER THE PAST FORTY PLUS YEARS THAT I HAVE
BEEN WITHIN THIS BUSINESS, I DO NOT KNOW OF ANY INSTANCES THAT
THE FUEL SYSTEM HAS CAUSED ANY FIRES. WE HAVE HAD SOME TANKS
THAT WERE EXPOSED TO CLOSE BUILDING OR EQUIPMENT FIRES. THE
TANKS THAT WERE EXPOSED, BUILT AFTER 1984, UNDER EDITION SIX U/L
142 STANDARDS, DID NOT ADD TO THE FIRE. THEY JUST STAYED
DORMANT, AND AFTER THE FIRE THEY WERE CHECKED OUT, TESTED,
REPAINTED, AND PLACED BACK INTO FULL SERVICE.
FROM THE ABOVE INFORMATION, WE THEREFORE ARE ASKING THE CITY
OF TIGARD TO ALLOW US TO USE ONE FIFTEEN THOUSAND GALLON TANK,
3
FOR THE STORAGE AND DISTRIBUTION OF DIESEL FUEL INTO THEIR
• EQUIPMENT.
THIS TANK IS U/L 142 WITI -I: MONITORED 100% + FULLY SECONDARY
CONTAINMENT, WITH A SEISMIC FOUR FREE STANDING RATING,
THE REQUIRED PRIMARY AND SECONDARY EMERGENCY VENTING,
THE REQUIRED HIGH LEVEL.90% LIMITING TO FULL VALVE, THE
REQUIRED ANTI - SIPHON VALVES, AND ALL OF THE REST OF THE
REQUIRED EQUIPMENT. THE TANK, BY FIRE CODE DIRECTION, IS
PAINTED WHITE, FOR THE REFLECTION OF ALI.. INCOMING RADIATED
HEAT.
THIS SYSTEM IS VERY NEAT, ORDERLY, NON -BUSY LOOKING. IT IS
CONSIDERED BY BOTH. FIRE AND PLANNING DEPARTMENTS, TO HAVE
AN ACCEPTABLE EYE APPEAL, AND LOOKS LIKE IT BELONGS THERE.
THEREFORE, IT DOES NOT STAND OUT LIKE A SORE EYE. THE ONE TANK
WILL TAKE UP LESS SPACE AND WILL BE TEN FOOT I- IIGI -I, THIRTY -TWO
FEET LONG, AND IN A CYLINDRICAL DESIGN, BUILT ON SADDLE
SUPPORTS. A THREE TANK SYSTEM LOOKS VERY BUSY, HARD TO KEEP
THE TANK AND AREA CLEAN, AND HAS A TANK FARM EYE APPEAL.
AS YOU CAN SEE, WE COULD GO ON AND ON ABOUT THIS AND THESE
SYSTEMS. THEREFORE, I WOULD REQUEST THAT YOU REVIEW THE
THE ABOVE, AND REQUEST ANY INFORMATION THAT I MAY HAVE
OVERLOOKED.
WE DO APPRECIATE YOUR OPEN MINDED APPROACH TO WORKING WITH
US TO PROVIDE THE SAFEST, GOOD LOOKING SYSTEM, THAT IS
AVAILABLE TODAY.
THANKS AGAIN, IT IS INDEED A PRIVILEGE TO WORK WITH YOU AND
YOUR CITY.
RESPECTFULLY SUBMITTED;

RE: Rax Transportation New A/G Fuel Tank
PC #: 4 -96c BUP #: 97 -0204
Dear Art:
•
As you verbally requested, this letter is in response to the May 1, 1997 letter to you
from the City of Tigard regarding the installation of an aboveground storage tank at
the Rax Transportation facility in Tigard.
The project includes the installation of a 15,000 gallon aboveground fuel tank on an
existing concrete slab on grade. The tank will be manufactured by Brown- Minneapolis
Tank.
1. Plans, Specifications and calculations
a. On May 2 I visited the facility to observe the existing concrete pad. Ron Hamilton
with Rax stated that the slab was constructed in 1949. Buses were parked on the
slab. The slab measured approximately 20 feet by 32 feet by 8- inches thick. The slab
thickness was determined by excavating the ground adjacent to the slab in three
locations. Subsurface soils were a very compact silty sand. A level was used to
measure that the grade of the slab was flat. A crack was observed in the slab that
separated the slab into two 10 by 32 foot sections. No displacement was observed
and the crack is considered a normal shrinkage type crack as control joints are not
present. These observations indicate that the slab has been considerably pre - loaded,
observable settlement has not occurred and the concrete appears in good condition.
Calculations were performed in order to check the tensile and shear stress in the
concrete and the bearing pressure of the subgrade. These calculations assumed that
the slab is eight inches thick, has a compressive strength of 3,000 pounds per square
inch and that reinforcing steel is not present. These calculations indicate that a
baseplate is needed under the saddle supports in order to reduce the tensile stress in
the bottom of the concrete under the saddles to a reasonable stress. The required
base plate area is 30 inches by 140 inches. The required baseplate thickness is 1/2-
inch (36 ksi yield strength, see attached work sheets]. Each corner of the baseplate
should be bolted to the slab with 3/8 -inch bolts having a minimum of 2- inches of
embedment.
•
The edge of the tank saddle support (not the added baseplate) should be a minimum of
2 feet away from the edge of the slab.
b. The tank overturning review indicates that the tank will not overturn (see attached
worksheets).
c. The foundation bolting may performed using six 1.25 inch diameter Parabolts or
nine 1.00 inch Parabolts per each of tie two saddle supports (see attached
worksheets). Bolt in accordance with manufacturer's instructions. Bolt through both
. the saddle and added base plate.
d. You reported that welding tabs will not be used and that other structural field
welding will not be performed. Therefore, welding tab information is not needed.
2. Special Inspections
1. The special inspection program is required for the tank saddle to slab bolting. We
discussed that I would perform the special inspection.
2. I have assumed that you will have the owner sign the Structural Special Inspection
form.
If you have any questions or need additional information please call me at 503 -803-
9163.
