CASCADE BOULEVARD nATE: DECEMBER 14, 1981 On December 8, 1961 , at the request of Mr. Wi 'iliarn Ford of Pargas of Portland, Incorporated, an inspection was made of the nei 30,000-gallon capacity propane storage tank currently being installed at the Tigard gas plant as noted above. This installation was the subject of cur letter of plans review dated Decem- ber 29, 1980. included in this file. The inspection revealed that the container was marked for above-ground installation, it had a water, capacity of 30,000 gallons, the design working pressure was 250 psi with the product being at 1250 F, that it had an outside surface area of 1 ,888 square feet. Three relief valvas are installed at the west end of the tank and are equipped with risers of 7 feet in height. Each relief valve has a capacity of 11 ,812 cubic feet per minute (air) making a total combined capacity of 35,436 cubic feet per minute (air) thus having a capacity of 9,389.7 cubic feet per minute (air) above that which is required for the surface area of the tank. At the time of this inspection, the plumbing of the piping to and from the container was in process. Pargas personnel at the container site advised that they would contact this office for a pressure test and final inspection of the piping once the plInrrbing has been completed. ! . q the aforementioned letter of plans review, items 1 , 2, 3, 4 and 5 h:!ve he n atisfied. Items 6 through 8 must be verified on final inspection. xc : I ld Wa l dr'n William Avery 'Ailliam Ford Fire prevention does no!cost it pays BUILDING PERMIT APPLICATION TIGARD DA*rr - -_-_ ts___ 3782 THf=UNDERSIGNED HEREBY APPLIES FOR A PERMIT FOR THE WORK HEREIN 114DICATED BUILDER PHONE ' OR AS SHOWN AND APPROVED IN THE ACCOMPANYIN,.3 PLANS AND SPECIFICATIONS.

Box. ?.3067 Portland, Oregon 97123 Dear Mr. Avery: Enclo_.ed herewith is a copy of a memorandum which I received this morning from Bill Walls of NFPA. Since you are in the process of installing a new container and since the subject matter of this memorandum will ultimately have an impact upon your facility on Cascade Boulevard, I thought it may be of interest to you. C:ery tr y yours, , I f(jN Y FIRE DIST! ( ' NO.

L. Walls, Gases Field Service Engineer �. I Subject: Installation of Emergency Shutoff Valves Date: January 9, 1981 According to NFPA records , you are Engaged in the promulgation and/or enforcement of regulat-,ons covering stationary LP-Gas facilities in your jurisdiction,. In most instanzes , you have used NFPA 58, Storagr: and Handlinu of Liquefied Petroleum Gases, in this activity - either by adopting it by reference or by incorporating its provisions in regu- lations developed by yourse' ves. By whatever approach yju have used, you have, of course, been required to adopt or inco,-porate a specific edit-on of NFPA 53. Where an approach other than strict adoption by reference has been used, some provisions in NFPA 58 may have been modified or even ornitted in the regulations. The purpose of this memo is to call your attention to one provision in NF"A 58 that is expected to have a great impact upon improved fire safety - so much so that you may wish to take irnmed-iate steps to implement it in your jurisdiction. In the mid-1970' s, a Joint Task Force of the NFPA Committee ort Liquefied Petroleum Gases (which is responsible for NFPA 58) and the National LP-Gas Association (the major trade association for the LP-Gas industry) conducted a study of the fire experience of the large instal- lations - concentra"ng on tile factors leading to explosive container failure (the Boiling Liquid-Expanding Vapor-Explosion , or BLEVE) . This study showed: 1 . In nearly all cases, the fire expnsure that caused the BLEVE was burning LP-Gas escaping from ruptured hoses or damaged piping or as a result of hose coupling failure. EXECUTIVE OFFICE:470 ATLANTIC AVENUE, BOSTON,MASSACHUSETTS,USA.02210- tFLEPHONE AREA -ODE(61 7)482.8755 - TELEX 94-0720 The non-pmfff We nanl and ndurahr l omon,ronpr.To Promoro Nr r;e<e ona­Pmro Ifie merf.-d,of f,a Prow'non and pre.rn— io cbam and c.m Taro nformonon on If-.w fubR'QI and to wvre the coaperrnon of"members and Mro p,,blic in efrnblishing proms.ofegua.ti,agnma lots of life rind propeM by Ire. �r -2- 2. in nearly all cases, the LP-Gas escape was associated with liquid transfer operations involving cargo vehicles or rail- road tank cars a�. well as the stationary storage containers. 3. In cases where a cargo vehicle was involved, the damage to hoses and/or piping was the result of an attempt to move the vehicle while hoses were still connected. 4. Excess-flow check valves did not operate for a variety of reasons - including breakage not large enough to result in a flow "sufficiently" excessive for the rated closure point of the valve and damaged or inoperative valves. 5. The containers that BLEVE'd were those on the cargo vehicles and railcars as well as those in storage service. Based upon this study, it was concluded that the excess-flow check valve could not be relied upon as the sole means for providing the needed degree of safety in certain facilities covered by NFPA 58. On November 16, 1976, the 1976 edition of NFPA 58 was adopted by the NEPA. Par. 3168 was added in this edition. This paragraph specified the installation of a so-called "emergency shutoff valve" on certain LP-Gas systems - essentially t�•:� larger systems where the experienc- ce Fa-d clearly revealed a need. Par. "i168 stipulated a date of December 31 , 1978 by which all pertinent installations should be equipped with this protection. As regulators, you will recognize that such a retroactive provision is unusual and indicati .—e of the reed for such protection in the view of the Committee and the NFPA. This date was subsequently changed to December 31 , 1980 by a Tentative Interim Amendment. This was found to be necessary for valve development and listino. On May 17, 1979., the current (1979) edition was adopted by the NFPA. In addition to a date of December 31 , 1980, Par. 3168 was amended sub- sequently by two Tentative Interim Amendments. TIA 58-79-1 required immediate compliance with 3168 on new installations rather than by December 31 , 1980 (this TIA is published on page 181 of the 1979 edition) . This action is a further manifestation of the need for this protection. TIA 58-79-2 was published in the Mav/Jane 1980 issue of the NFPA "Fire News" and points out that: more than cne emergency shutoff valve may be needed in piping arrangements where more than one hose is used. December 31 , 1980 has now passed. While we know that many instal- lations are n;w in compliance with Par. 3168, it is extremely doubtful -3- that all of those that should be are in compliance. I firmly believe that it is in the best interests of those you serve to have this provision an accomplished fact in your ,jurisdiction as soon as possible. We all recognize that we must be pract cal in attaining this goal , There will undoubtedly be delays due, if to nothing else to problems with weather in the Northern areas of the USA and Canada. However, the initial problems of equipment availability, and design are behind us. One of the problems reported to NFPA is that some of you are encumbered with older editions of NFPA 58 (or provisions based upon them) on your statutes. From 18-Flus years of working with you, I am well aware of your problems o` keeping current with NFPA standards - especially if you have not adopted them by referr ice, Usually, a lag of an edition or two is not serious. However, from the standpoint of Par. 3168 alone, : urge each of you with editions of NFPA 58 older than the 1976 edition "on the books" (or provisions based upon them) to immediately take steps to update to the 1979 edition. To allay any concerns you might have about possible industry objections, I 'm assured that. the Safety Committee of the National LP-Gas Association will support such an action on your part. Finally, as I 'm sure you are aware, I ' ll he glad to assist you further in any way that I can. c,�: Skip Smith, Pat Jordan cc: Members of LPG COM I NGTON CSG 20665 S.W. Blanton St. P.O.

Box 23067 Portland, Oregon 97223 Dear Mr. Avery: The plans for the installation of the new 30,000 gallon capacity propane storage tank which we requested in our letter to your firm of November 24, 1980, were received in this office on December 2 and have now been examined with reference to applicable fire safety regulations. The scope of the submitted plans and the information which they contain is e�gdin �i ed. No doubt all of the following requirements are eing provided for in the actual installation. However, we were unable to determine that they were being provided for in the drawings which we received. In any case, we are listing as follows requirements which must be addressed during the course of installation and for which we found no provisions in the construction documents submitted to us. 1 . The container must bear the following markings: a. the service for which the container is designed; i .e. underground or above ground service or both. b. the name and address of the supplier. c. the water capacity of the containers in U.S. gallons. d. the design pressure of the container in pounds per square inch gauge. e. wording prohibiting the filling of the container with a product having a vapor pressure in excess of the maximum design pressure of the container at 100 degrees Fahrenheit. f. the outside surface area of the container in square feet. Fire prevention does not cost...it pays Mr. William Avery December• 29, 1980 Page 2 2. The container must be fitted with a safety relief valve or valves set to discharge at not less than 88 percent and not more than 120 percent of the design pressure of the container. The safety relief valve or valves must be located to be in constant contact with the vapor space of the container and must be fitted with dis-:harge pipes to the effect that they will discharge upward and away from the container at a point not less than 7 feet above the top of the container shell . The discharge pipes must be fitted with rain caps to prevent rain, snow, ice, wind born debris, etc. from collecting within them and from obstructing the discharge capacity in any way. Provisions must be made for draining condensate from the relief valve discharge in such a manner as to protect the container against flame impingement which might result from ignited products escaping from the drain opening. The relief valve or valves must have a discharge capacity (or aggregate discharge capacity) to effectively provide relief from internal pressures within the container based upon the surface area of the container. The required discharge capacity or aggregate discharge capacity in cubic feet per minute (air) may be calculated by taking the surface area of the container, in square feet, to the 0.82 power and multiplying the results by the constant of 53.632. Thus, for example, a container having a total surface area of 3,000 square feet (according to our cal- culations) would be required to have a relief valve discharge capacity of 38,077 cubic feet per minute (air) or 3,000 to the 0.82 power equal 709.969 times 53.632 equal 38,077.061. Each container relief valve must be fitted with a permanently attached plate or marking indicating the start to discharge pressure in pounds per square inch gauge and the actual discharge rate in cubic feet of air per minute at 60 degrees Fahrenheit and 14.7 pounds per square inch atmospheric pressure. 3. All container openings exclusive of those used for safety relief valves, liquid level gauging devices, pressure gauges, and plugged openings must be equipped with a positive shutoff valve and either an excess flow or back flow check valve, depending upon the function of the opening. Excess flow and back flow check valves must be located between the contai^er and shut off valves either inside the container or at a point immediately outside where the line enters or leaves the container, as the case may be. If outside, the installation must be made fir. W 11 iam Avery Decemher 29, 1980 Page 3 so that any endue strain beyond the excess flow or back- flow check valve will not cause breakaan hetween the container or the valve. All connection lead- ing to or from any individual opening f eh an excess flow valve must have a capacity g, an the rated flow of the valve. All valves, gauges and other appurtenances must protected against. damage. All container inlet ar connections except for safety relief valves, liquid level gauging devices and pressure gauges must be labeled to designate whether they coruminicate with the vapor or the liquid space viithin the container. Labels may be attached to the valves controlling the inlets or outlets. 4 . The container must be provided with a liquid level gauging device which may be of the -1 ;N Lube, rotary tube or float types and in addit=un, if the container under discussion was constructed aster Decemier 31 , 1965, it must be equip- ped with a fi:;ed liquid level gauge to indicate the maximum filling level for the service to which the ontainer is einp i o2ted. If the gauging devices, as mention bleeding of product to atmosphere, nc have a maximum opening equivalent . o that of grill size or less unless equipped with an excess i uv. eve. S. The container must be fitted with a pressure gauge attached directly to a container opening or to a valve or fitting which is directly attached to a container opening. If the opening will permit a flow greater than that of a No. 54 drill size, an excess flow check valve (Dust be provided for the pressure gauge opening. 6. All piping, fittings , valves , etc. used in connection with this installation must be constructed of steel , ductile iron, malleable iron or brass. All such devices must be listed by UL Incorporated or A.G.A. for LP ga.; service and must have a design working pressure of not less than 250 psig except where subjected to pressures in excess of 2.50 psig such as on the discharge side of transfer pumps, in which case they must have a designed working pressure of 350 psig. Gaskets must be of metal having a melting point of not less than 1500 degrees Fahrenheit or 'Dust be protected against fire exposure. Mr. William Avery December 29, 1980 Page 4 At all points in the liquid piping system where LP gas in the liquid state may be trapped between shutoff valves, pressure relief valves must be provided. Said pressure relief valves must be set to discharge at not less than 400 psig and not over 500 prig. 7. Ali piping must be suitably supported, protected and braced or fitted with flexible connections to prevent strain to the piping system arising from settling, heaving, vibration, expansion, contraction, etc. 8. Prior to the placing of the piping system and container in service, all joints, fittings and valve connections must be tested and proven leak-free in the presence of a representative of this office. Subject to the foregoing comments and stipulations, the plans under dis- cussion are hereby approved.
