Swiecicki, National Propane Gas AssociationComment on Proposal No:58-75Recommendation: Edit definition to read as follows: 3.3.47 Overpressure Shutoff Device. A device that shuts off the flow of LP-Gas vapor through a regulator when the outlet pressure of the regulator reaches a predetermined maximum allowable pressure.Substantiation: This editorial change will make clear that the term defined as an overpressure shutoff device refers to a part of the regulator and it shuts off the flow through the regulator.Committee Meeting Action: RejectCommittee Statement: The overpressure shutoff device can be a separate device, which would not be allowed under the proposed definition.Number Eligible to Vote: 30Ballot Results: Affirmative: 12 Negative: 15 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARDExplanation of Negative: BOGAN: Refer to Mr. McTierʼs comment. I feel that the committee needs to re-group and take a second look at this item. BRUNNER: Refer to McTierʼs comment. FAULHABER: I cite Sam McTierʼs arguments for reconsidering these items. HAYES: This should be looked at again and reconsidered. HOFFMAN: It is my understanding that significant issues exist with this item and it should be revisited. KEEPERS: Overpressure shutoff devices. This can be separate device not necessarily part of a regulator. This needs some review. LEWIS: I concur with Mr. McTier. MAXON: A separate device as opposed to integral part should be considered. MCTIER: This comment addressed the definition of an overpressure shutoff device as follows: “3.3.47 Overpressure Shutoff Device. A device that shuts off the flow of LP-Gas vapor through a regulator when the outlet pressure of the regulator reaches a predetermined maximum allowable pressure.” The Committee Meeting Action was to reject and the Committee statement was as follows: “The overpressure shutoff device can be a separate device, which would not be allowed under the proposed definition.” The reason for rejecting this comment by the Committee is not valid as a separate overpressure shutoff device that is installed downstream of a regulator shuts off the flow through the regulator when activated. An overpressure shutoff device shuts off the flow through the regulator whether it is integral with the regulator or is installed as separate device downstream of the regulator. This should be reconsidered by the Committee and 58-10 should be accepted. MISEL: Refer to Mr. McTierʼs comment. MORTIMER: This should be looked at again and reconsidered. PHILLIPPI: The reason for rejecting this comment is not valid. A separate overpressure shutoff device that is installed downstream of a regulator shuts off the flow through the regulator when activated. An overpressure shutoff device shuts off the flow through the regulator whether it is integral with the regulator or is installed as a separate downstream of the regulator. Acceptance should be reconsidered by the Committee. STANNARD: The code would be much improved if the commentorʼs original language had been accepted. STERNOLA: This comment addressed the definition of an overpressure shutoff device as follows: “3.3.47 Overpressure Shutoff Device. A device that shuts off the flow of LP-Gas vapor through a regulator when the outlet pressure of the regulator reaches a predetermined maximum allowable pressure.” The Committee Meeting Action was to reject and the Committee statement was as follows: “The overpressure shutoff device can be a separate device, which would not be allowed under the proposed definition.” The reason for rejecting this comment by the Committee is not valid as a separate overpressure shutoff device that is installed downstream of a regulator shuts off the flow through the regulator when activated.

The more common term for relief devices where the fluid pressure exceeds the set point is a ʻHydrostatic Relief Valveʼ. A description of this type of valve appears in 2.4.7 and 3.2.21. The striking of the word ʻfluid ̓will accurately describe the intent of the paragraph.Committee Meeting Action: AcceptNumber Eligible to Vote: 30Ballot Results: Affirmative: 27 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARD

The initial fill of LP-Gas in a transportation or storage system that has been converted from ammonia to LP-gas service shall be tested for ammonia contamination prior to being used or transferred from that system.Substantiation: The revised version that is similar to the requirement shown in 1-1.1 of the 1998 Edition explains what has to be done and why. What is vague is the revision to the code for the 2001 Edition of NFPA 58 that was not noticed by the Committee.Committee Meeting Action: AcceptNumber Eligible to Vote: 31Ballot Results: Affirmative: 27 Vote Not Returned: 4 KASTANAS, REZA, ZEPP, WARD

_______________________________________________________________58-21 Log #25 Final Action: Accept in Principle( 4.6 )_______________________________________________________________Submitter: Bruce J. Swiecicki, National Propane Gas AssociationComment on Proposal No:58-3Recommendation: Revise Committee Action as follows: Based on the Preprint in the ROP, insert a new Section 4.6 as follows: 4.6* Minimum Requirements. For any purpose or application addressed within the scope of this code, should the minimum requirements of the code be met, additional features or components of equipment not prohibited by the code shall be permitted to be used. Add a new paragraph in Annex A: A.4.6 The installation of safety enhancing equipment that is not otherwise required by this code is permitted by the code to be used. This includes any device that performs a safety related function even though the device is designed or named to perform a required function. For example, an “emergency shutoff valve” (ESV) is installed in a location where it is not required to provide all the safety functions of an ESV. Even though the installer uses it to provide a specific feature that may be common to all ESVʼs, the code would still not require compliance with all of the ESV provisions, for example the closing requirements, described in Section 2.4.5.4. Substantiation: The NFPA 58 Technical Committee is correct that Chapter 1 is not the appropriate place for this proposal. The text is proposed to be moved to the new chapter 4 to ensure it applies to the entire code and not just chapter 3. This proposal will support the long standing concept that the requirements of NFPA 58 do not prevent the use or installation of equipment which may exceed the performance required by the code. For example, a bulk plant operator may wish to install a device, such as a valve, that achieves a greater level of safety than the code requires for a particular installation. The bulk plant operator should be free to exceed the requirements of the code to the degree desired without being penalized by the authority having jurisdiction.Committee Meeting Action: Accept in Principle Add text to read as follows: 4.6* Minimum Requirements. For any purpose or application addressed within the scope of this code, where the minimum requirements of the code are met, additional features or components of equipment not prohibited by the code shall be permitted to be used.

Report on Comments — Copyright, NFPA NFPA 58 Substantiation: The chapters are reorganized to allign section numbers to cover the same subjects in chapter 6. No technical changes were made. This restructuring does not inculde revisions made in other comments and the NFPA editorial staff is requested to incorporate them.Committee Meeting Action: AcceptNumber Eligible to Vote: 30Ballot Results: Affirmative: 22 Negative: 3 Abstain: 2 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARDExplanation of Negative: MAXON: I feel this item needs further review by the full committee. PHILLIPPI: This comment covers matching Chapter 5 “Equipment Descriptions” with Chapter 6 “Installation Requirements” and was accepted by the Committee without receiving a finished product. Out of 156 potential matches of sections and subsections between Chapter 5 and Chapter 6, there are only 30 matches shown in the finished table that match equipment descriptions with installation requirements. Suggest reversal of the Committee decision and vote against this comment and reject it. STANNARD: See my comment on 58-10 (Log #253).Comment on Affirmative: FREDENBURG: The realignment was a tedious effort that I spent a lot of time on. Even then, not being able to see a printed version of the involved chapters and how this alignment works leaves some doubt in my mind, and I am the one most familiar with it. Sam makes a good point about the committee being asked to approve it without seeing it. I think it will work, but allowing the committee to see the realigned chapters would reassure everyone.Explanatin of Abstention: MCTIER: I have concerns over the renumbering of Chapters 5 and 6. Therefore I change my vote from negative to abstain. MIZEL: Concur with Mr. McTier.

(See 3.3.35, LP-Gas System.)Substantiation: As a matter of style throughout most of the code, Section titles are listed with no added copy on the same line. Copy is added in the next line below the title. This is also true in most cases for subsection titles when multiple paragraphs follow the title. We should be consistent in this style rather than going back and forth; therefore, sections and subsections where necessary have been corrected throughout the code. Also, after a colon the template automatically puts in parenthetical numbers for a listing.

Swiecicki, National Propane Gas AssociationComment on Proposal No:58-75Recommendation: Revise Section 5.2 as follows: 5.2 Containers. 5.2.1 General 5.2.1.1 Containers that show excessive denting, bulging, gouging, or corrosion shall be removed from service. 5.2.1.2 Repair or alteration of a container shall comply with the regulations, rules, or code under which the container was fabricated. 5.2.1.3 Field welding shall be permitted only on saddle plates, lugs, pads or brackets that are attached to the container by the container manufacturer. 5.2.1.4 Containers for general use shall not have individual water capacities greater than 120,000 gal (454 m3). 5.2.1.5 Containers in dispensing stations, not located in LP-Gas bulk plants, industrial plants, or industrial applications, shall have an aggregate water capacity not greater than 30,000 gal (114 m3). 5.2.1.6 Heating or cooling coils shall not be installed inside storage containers. 5.2.1.7* Containers shall be designed, fabricated, tested, and marked (or stamped) in accordance with the regulations of the U.S. Department of Transportation (DOT), the ASME Boiler and Pressure Vessel Code, Section VIII, “Rules for the Construction of Unfired Pressure Vessels,” or the API-ASME Code for Unfired Pressure Vessels for Petroleum Liquids and Gases, except for UG-125 through UG-136. (A) Adherence to applicable ASME Code Case Interpretations and Addenda that have been adopted and published by ASME 180 calendar days prior to the

effective date of this code shall be considered as compliant with the ASME Code.(B) Containers fabricated to earlier editions of regulations, rules, or codes listed in 5.2.1.3 and of the ICC Rules for Construction of Unfired Pressure Vessels, prior to April 1, 1967, shall be permitted to be continued to be used in accordance with 1.4.shall be permitted to be continued to be used in accordance with 1.4. 5.2.1.8 Containers that have been involved in a fire and show no distortion shall be requalified for continued service before being used or reinstalled. (A) Cylinders shall be requalified by a manufacturer of that type of cylinder or by a repair facility approved by DOT. (B) ASME or API-ASME containers shall be retested using the hydrostatic test procedure applicable at the time of the original fabrication. (C) All container appurtenances shall be replaced. 5.2.2 Cylinders 5.2.2.1* Cylinders shall be continued in service and transported in accordance with DOT regulations. 5.2.2.2 Any cylinder where the with an expired requalification date has been passed shall not be refilled until it is requalified by the methods prescribed in DOT regulations. 5.2.2.3 DOT cylinders in stationary service that are filled on site and therefore which are not under the jurisdiction of DOT, shall either be requalified in accordance with DOT requirements or the following shall be visually inspected within 12 years of the date of manufacture and within every five years thereafter, in accordance with the criteria (A) through (C): (A)Any cylinder that fails one or more of the criteria in (C) shall not be refilled or continued in service until the condition is corrected. (B)Personnel shall be trained and qualified to perform inspections. Training shall be documented in accordance with Section 1.5. (C) Visual inspection shall be performed in accordance with the following: (1) The cylinder is checked for exposure to fire, dents, cuts, digs, gouges and corrosion according to CGA C-6, except that paragraph 4.2.1.1(1) of that standard (which requires tare weight verification), shall not be part of the required inspection criteria. (2) The cylinder protective collar (where utilized) and the foot ring are intact and are firmly attached. (3) The cylinder is painted or coated to retard corrosion. (4) The cylinder pressure relief valve indicates no visible damage, corrosion of operating components, or obstructions. (5) There is no leakage from the cylinder or its appurtenances that is detectable without the use of instruments. (6) The cylinder is installed on a firm foundation and is not in contact with the soil. (7) A cylinder that passes the visual examination shall be marked with the month and year of the examination followed by the letter “E” (example: 10-01E, indicating requalification in October, 2001 by the external inspection method). (8) The results of the visual inspection shall be documented and a record of the inspection shall be retained for a five year period. 5.2.1.82.4 DOT 4E specification (aluminum) cylinders involved in a fire shall be permanently removed from service. Substantiation: The editorial changes proposed above will greatly simplify the application of Section 5.2 because: 1. Requirements applicable to both ASME and DOT containers will appear under the “General” heading. 2. Requirements applicable to either ASME or DOT containers, but not both, will appear under each respective heading. 3. Other re-orderings to clarify the hierarchy of requirements appears in proposed Section 5.2.2.3. 4. The editorial clarifications proposed in 5.2.2.2 will improve the language. “Whose” is usually used as a personal pronoun and its use with equipment is archaic.Committee Meeting Action: AcceptNumber Eligible to Vote: 30Ballot Results: Affirmative: 27 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARD

These cylinders need to be hydrostatically tested like all other pressure vessels. A visual inspection is not enough to determine if the pressure vessel is safe. This subject was of great discussion at the meeting this document was voted on in the last cycle and was soundly defeated. There has been no new information brought forward that would change the previous action that would require hydrostatic testing to be eliminated from the code.Committee Meeting Action: Reject

Report on Comments — Copyright, NFPA NFPA 58 Committee Statement: The committee notes that NFPA 58 references the DOT cylinder requirements, including retest requirements. DOT allows 3 methods of requalification, and the committee also allows these 3 in NFPA 58. The committee was advised that the Propane Education and Research Council has sponsored a project, conducted by Battelle Laboratories in which the visual requalification was revalidated. The report of PERC project no. 10202 is available from the PERC web site, www.propanecouncil.orgNumber Eligible to Vote: 30Ballot Results: Affirmative: 26 Negative: 1 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARDExplanation of Negative: HAYES: It is my belief that a visual inspection is not enough. Cylinders need to be removed and tested. Cylinders are known to rust at the bottom, inside of the base ring (DOT), where a visual cannot be adequately performed. I think that damaged cylinders will be missed._______________________________________________________________58-26 Log #29 Final Action: Accept( 5-2.1.8 [2-2.1.7 Old] )_______________________________________________________________Submitter: Bruce J.

(See 5.3.2Substantiation: This section has been renumbered to comply with the manual of Style. It is our recommendation to delete 5.3.4.3 and Table 5.3.4.3 as they are not needed. The inlet and outlet connections are already covered in Table 5.3.4.1 and other sections of Chapter 5 and 6. We also changed Table 5.3.4.1 to cover 4000 gal water capacity containers in the 2001 Edition of NFPA 58. A short history of the changes proposed on Table 2.3.3.2(a) and 3.3.3.6 in the 2001 Edition are as follows:“When we changed old Table 2.3.3.2(a) (new Table 5.2.4.1) to cover ASME containers through 4000 gal water capacity instead of through 2000 gal water capacity, there was some concern as to how to fit up containers for bulk plant and industrial plant use where the aggregate capacity was between 2001 through 4000 gal water capacity. Since we had a bulk plant and industrial plant Section 3.3, we thought that we might address it in that location, and we attempted to separate this from bulk and industrial plants with an aggregate water capacity of more than 4000 gal. We ended up putting in redundant requirements that were covered in old 2.3.3.2 into 3.3.3.6 for bulk and industrial plants over 4000 gal water capacity and then we attempted to mix in the requirements for 2001 through 4000 gal into the same section, . As these small multicontainer plants generally utilized standard 1000 gal water capacity domestic ASME containers, there was nothing new to be drawn from separate coverage other than to give one the option of using internal valves, although not requiring it on these smaller plants. In addition there was really no good reason for duplicating what was stated in 2.3.3.2 in 3.3.3.6. With approval from NPGA and the NFPA Committee, our plan is to eliminate all of old 3.3.3.6 and reference new 5.3.4.2 and take no action on the small multicontainer bulk and industrial plants as it is already well covered in old Table 2.3.3.2(a) (new Table 5.3.4.1) New Table 5.3.4.3, and 5.3.7).”Committee Meeting Action: Accept in Principle1. Revise text to read as follows: 5.3.4 Container Connections and Appurtenances. 5.3.4.1 Containers of 2000 gal (7.6 m3) water capacity or less, shall comply with Table 5.3.4.1 .

(4) A backflow check valve that is designed for the intended application and is installed in the line upstream as close as practical to the existing positive shutoff valve

Substantiation: A table that would clearly state the detailed appurtenance requirements for containers over 4000 gal water capacity that includes the new installation of and the retrofit requirements for internal valves plus many other details makes it extremely difficult to accomplish. The rewriting of this paragraph on appurtenances and all of the alternative ways to fit up and retrofit these containers is also very difficult to write . The use of a table as without a written version is not a good idea for many of the people that read and use this code. If done correctly, the detail makes it as cumbersome as the the written version. If the editorial task force insists on putting in a table, it should then be included in addition to the written version. The proposed table shown above is inadequate and does not cover all of the details of the requirements. For instance, there is no mention of the requirement for including a remote shutoff on all of the internal valves in liquid service. It is not clearly stated that internal valves in liquid service that were installed prior to the requirement must be equipped with remote shutoffs and thermal protection by July 1, 2003. It also does not require emergency shutoff valves where they are used for retrofitting to be installed as close as practical to the positive shutoff valve of a combination shutoff valve and excess flow valve installed in the container, etc. I will be happy to vote for the inclusion of the new Table 5.3.4.3 that the editorial task force and I drew up together with the editorial task force doing most of the work. It covers most of the details of the written version, but I strongly believe that we need both. If we have to change the requirements to accommodate a table, we do not need it or want it.

RT: Equipping an existing internal valve for remote closure and automatic shutoff using thermal (fire) actuation within 5 feet of the internal valveSubstantiation: This is an editorial clarification. As currently worded (2001 edition), both Sections 2.3.3.2 and 3.3.3.6 are difficult, at best, to comprehend and apply. This table addresses all aspects of each section, whereas the tables (5.3.4.3 and 5.3.4.4) appearing in the preprint do not transfer all the necessary detail from the text, and are therefore substantive changes.Committee Meeting Action: Accept in Principle The table is combined with Table 5.3.4.3 in the preprint and is revised: (See Table 5.3.4.3 on the following page.) Add to the note, IV: “...or an Excess Flow Valve with a fail closed hydraulically or pneumatically actuated valve in compliance with API 607 Fire Test for Soft Seated Quarter-Turn Valves, equipped for remote closure and automatic shutoff using thermal actuation where the thermal element is located within five ft. (1.5 m) of the valve. “Committee Statement: The concept of the propossed table Table 5.3.4.3, combining 2 tables as shown in the preprint is accepted. A revised table combining the advantages of the preprint and the proposed table is substituted.

Stookey, Phoenix Fire DepartmentComment on Proposal No:58-44Recommendation: Revise Section 2.4.6.3(b) as follows: 5.4.6.4(2) Hose assemblies, after the applications of couplings connections, shall have a design capability of not less than 700 psig (4.9 Mpag). After the couplings are applied, hoses used for vapor service at a pressure of more than 15 PSIG or hoses used for liquid service shall be pressure tested. When if a pressure test is performed, such assemblies shall be leak pressure tested at 120 percent of the pressures between the operating pressure and the maximum working pressure [350 psig (24 Mpag) minimum] of the hose. Hose assemblies shall be leak tested at time of installation at not less than the operating pressure of the system in which they are installed.Substantiation: As written this proposal does not stipulate that any hoses require a pressure test - instead, it only offers the minimum criteria if it is

decided that a pressure test is warranted. When this issue was discussed several individuals raised concerns regarding the need for pressure testing hoses for vapor service. The proposed language offers criteria for when pressure testing is required for hose assemblies. The 15 PSIG value is based on the value used by the ASME Boiler & Pressure Vessel Code as to its applicability for the construction of unfired pressure vessels. Secondly, the 15 PSIG value allows hoses installed in low pressure service regulators to be assembled but not require a pressure test. Assembled hoses that are used for liquid service should be pressure tested due to LPGs expansion ratio.Committee Meeting Action: RejectCommittee Statement: The committee notes that DOT has required automatic or remote shutoff of cargo tank vehicles, which provides a safe means to shut off the flow of propane in the event of hose failure.

During the filling operation the pilot and main burner must be turned off. In 4.2.3.2 the distance from the point of transfer to the heater is 25 ft and in 3.6.4.6 the distance is 15 ft.. • Direct gas-fired tank heaters can be replaced with modern safe equipment such as direct-fired vaporizers which are installed15 ft from fill connections and 10 ft from container surfaces. • Electric vaporizers can be installed with zero clearances. • Multiple storage containers which will increase vapor capacity can easily be installed and will provide for a safe system. • The installation of a direct gas-fired tank heater poses a safety problem when the delivery driver transfers product directly into the container. The pilot and main burner must be extinguished. Accidents have occurred when this requirement is not followed. Good codes do not force personnel to perform unusual acts. In heavy snow conditions the direct gas-fired tank heater causes an area around the container to melt down resulting in a void around the tank. If the transfer personnel extinguishes the pilot and opens

the fixed liquid during the transfer operations, plus product released during the disconnect from the filler valve, propane gas can accumulate in the void area. Accidents have occurred after the delivery person restored the hose on the truck and returned to relight the pilot. On a 1000 gal. tank this requires the person to lay on the ground and create a point of ignition in a possible gas accumulation. • A major propane distributor, years ago, created a company policy not to install, service or refill any container that was equipped with a direct gas-fired tank heater. This was due to several serious accidents which occurred as described. • This code modification would not prohibit the use of existing units in use, but would not allow new installations.

MCTIER: I voted negative because the preprint version of this paragraph did not comply with the 2003 Manual of Style, and also was too broad in scope. The term “allowed in buildings only for the following applications:” should be changed to “permitted to be located inside of buildings in accordance with the following:”. Section 2.2.1 of the MOS specifically covers language for permitted uses and the term “shall be permitted (to be)” shall be used. This requirement is a re-write of paragraph 3.2.2.1 in the 2001 Edition of NFPA 58 that stated: “LP-Gas containers shall be located outside of buildings”. It then lists seven exceptions and the term “only” was not used with these exceptions. MORTIMER: This should be looked at again and reconsidered. STANNARD: See my comment on 58-10 (Log #253).

These distances shall be permitted to be reduced by one-half for ASME containers of 2001 gal through 30,000 gal water capacity used in systems complying with Section 6.25.Substantiation: The rewrite clarifies the intent of this Section. Suggested subparagraph (5) in the ROP above is a staff editorial change from the 1998 Edition of NFPA 58 that was inserted into the 2001 Edition. Subparagraph 3-2.2.2(h) of the 1998 Edition covering distance requirements for buildings with overhanging structures started at the tenth line and stated the following: “Under no circumstances shall the distances to the building wall be less than those specified except when the provisions of 3.11.3 and 3.11.4 are met. These distances shall be permitted to be reduced by one-half for ASME containers of 2001 gal through 30,000 gal water capacity used in systems complying with Section 3-11 (present 6.25).” This concept should be inserted in place of proposed subparagraph (5) in the ROP as shown above. This is a far cry from exempting the container systems that comply with 6.25 from all of the requirements of proposed subsection 6.3.12. The same dangers are involved with 2001 gal to 30.000 gal water capacity underground or mounded ASME containers as to how to deal with a building projection of more than 5 ft that is less than 50 ft above the pressure relief valve outlet. The same applies to aboveground ASME containers that have the redundant safety features of old Section 3.11 (6.25) or meet the low emission transfer requirements of old Section 3.11 (6.25). As a result of the above, the proposed subparagraph (5) in the ROP should be deleted and the language shown above with the new corrected paragraph numbers should be inserted.

(a) A stake or other marking shall be installed higher than the highest anticipated average snow cover depths, up to a height of 15 ft (4.6m). (b) The installation shall prevent moving of the container by the forces as a result of snow accumulation. (c) The average snow cover depths published by the National Weather Service, in the installation area, shall determine if 6.6.3.6 applies.Substantiation: These changes identify the Committee vote on a Formal Interpretation on Section 3.2.6.5. The question ʻWas it the intent of the committee that tanks completely covered by snow for less than 30 days be required to have snow stakes?” The answer to the ballot was No. The modifications to this section remove words in the Code which are difficult to interpret and enforce. The words like ʻheavyʼ, ʻanticipated ̓and ʻexpectedʼ. Local Codes may substitute additions to this section in an unusual geographic area. The present wording could result in an interpretation to require snow stakes on millions of containers in the snow belt, if a snow storm covered the container for one day in one hundred years. The original intent was to provide guidance in higher elevations where the container is covered 4 or 5 continuous months of the winter season. The new wording excludes below ground container installations, however does include mounded containers.Committee Meeting Action: Accept in Principle Revise 6.6.3.6 to read: 6.6.3.6 In locations where heavy the monthly maximum depth of snow accumulation, as determined from the National Weather Service or other published statistics, is more than can be expected to cover the height of aboveground containers, excluding the dome cover the following requirements shall apply: (1) A stake or other marking shall be installed higher than the highest anticipated average snow cover depths, up to a height of 15 ft (4.6m).

Additional installations on the same roof or terrace shall be located at least 50 ft (15.2 m) apart.Committee Statement: Accepted with an editorial revision.Number Eligible to Vote: 30Ballot Results: Affirmative: 26 Negative: 1 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARDExplanation of Negative: STOOKEY: This change to the standard is not editorial. It is a technical change that was not considered by the whole committee during the ROP phase. It was proposed as an editorial change. This proposal would allow multiple 4,000-gallon w.c. installations on the roofs of high-rise buildings of types 443 and 332 construction when each installation is separated by at least 50 feet. This is a significant increase in the permitted amount of LP-Gas on roofs of high rise buildings. The 2001 edition of NFPA 58 currently limits the maximum amount of LP-Gas in ASME containers on high-rise building roofs to 4,000 gallons. This editorial change would allow an unlimited volume of LP-Gas storage on building roofs so long as the separation distance between each container or manifolded containers is at least 50 feet and the total amount of LP-Gas in each manifolded or single container is 4,000 gallons w.c. or less. For example, consider a high-rise building that has a roof measuring 120 feet by 120 feet in length and width. The proposal approved by the majority of the NFPA 58 committee would permit 4-4,000 gallon w.c. LP-Gas container installations on a hypothetical roof because a 50 foot separation is provided. The majority of the Committee has now authorized the installation of LP-Gas bulk plants on building roofs. The predominance of U. S. fire service membership has never sanctioned the installation of ASME containers on the roofs of buildings. The Phoenix Fire Department deleted this section when it adopted the 2001 edition. The Railroad Commission of the State of Texas which is a regulatory agency for LP-Gas in the State of Texas, also deleted this section. The installation of ASME containers on the roofs of high-rise buildings places firefighters at even greater risk when compared to buildings without ASME containers on their roofs. This proposal has increased the potential threat to the fire service and the public that we serve. The requirements for ASME containers on the roofs of high-rise buildings have always been flawed. As a fire service professional and Committee member, the other members of the NFPA 58 committee are aware of my goal to have this entire section deleted from the standard. The actions of the majority of the Committee on this proposal further reinforces my desire that one day the minimum level of safety for the storage and handling of LP-Gas can be raised. That day will occur when the majority of the NFPA 58 Committee recognizes that these installations are hazardous to the health and safety of firefighters and high rise building occupants and are not acceptable to the U. S. fire service.

Stookey, Phoenix Fire DepartmentComment on Proposal No:58-59Recommendation: The following amendments are offered to the proposal: 6.8.4.1 Polyethylene pipe, tubing and fittings shall be installed outdoors underground only. Exception No. 1: Polyethylene or other approved nonmetallic thermoplastic tubing may be used outdoors above ground where: (1) The tubing is used as part of a safety shutdown system where LP-Gas is used as the working fluid. (2) Tubing size is limited to a maximum of 1/4 in. (6 mm) outside diameter OD. (3) Pressure is controlled to prevent the formation of liquid. (4) Under emergency conditions, tThe LP-Gas supply is limited to 20 cu ft per hr (.56 cu m), and (5) Any flame from the LP-Gas supply will not impinge on a container or permanent piping.Substantiation: The proposed language is a good first step for allowing this common practice. At every bulk LP-Gas plant in the City of Phoenix, LP-Gas in vapor service is used as the fluid for operating emergency shutoff valves. Three proposal changes are suggested. First, other nonmetallic thermoplastic tubing is acceptable for LP-Gas service. While the section is titled “Polyethylene Pipe, Tubing and Fittings,” the fact remains that other acceptable thermoplastics are available and neither the user nor the AHJ should be restricted in its application for this particular use.

Insert a new 6.11 & 6.11.1: 6.11 LP-Gas vapor shall be permitted to be used as a pressure source for activating the remote shutoff mechanisms of internal valves and emergency shutoff valves. 6.11.1 Polyethylene and polyamide tubing shall be permitted to be installed outdoors above ground as part of a safety shutdown system and shall meet the following requirements: (1) The tubing is compatible with LP-Gas. (2) Tubing size is limited to a maximum of 3/8 in. (9.0 mm) outside diameter. (3)*Supply pressure is controlled to prevent condensation of the LP-Gas vapor. (4) The LP-Gas supply maximum flow to the system shall not exceed that from a No. 54 drill orifice. A .6.11.1 If LP-Gas vapor is supplied at container pressure and there is no flow, an ambient temperature drop below the container liquid temperature will result in condensation of the LP-Gas vapor. If the system is activated, the presence of liquid may result in a delay or malfunction of the system operation.Substantiation: There are numerous bulk plant installations in the United States that are successfully using LP-Gas vapor as a pressure source for activating remote shutoffs. Any pressure source offers different characteristics that must be considered in the design of a remote shut down system. LP-Gas is inexpensive, readily available, free of moisture and provides a reliable pressure source. When a remote shut down system utilizing LP-Gas vapor is properly designed, the system provides an equivalent level of safety to other pressure sources. The proposed system may also increase the level of safety by providing a reliable and readily available pressure source for activating the remote shutoffs. The proposed maximum tubing size has been increased from 1/4 in. to 3/8 in. OD to allow greater flexibility in system design. The quantity of gas released in the event of tubing failure is limited by an inlet orifice. The proposal allows the current systems that have been operating with no accident history to continue. Guidance for designing LP-Gas systems is provided in the appendix. The proposed guidance recognizes different environmental conditions that must be considered during the design phase of the system.

Many internal valves were installed prior to the requirement for their use on liquid withdrawal connections on containers. The retrofit requirements for the installation of internal valves or, as an alternative, emergency shutoff valves with remote closure operation and automatic shutoff by thermal means have a compliance date of July 1,2011. The committee decided that we should require the installation of the remote and thermal shutoffs and identified emergency remote shutdown stations on existing internal valves by July 1, 2003 rather than wait till July 1, 2011. If we leave this out, there will be nothing in the requirements to indicate that we want these features installed by July 1, 2003 and many internal valves that were installed before the 2001 Edition will not be retrofitted with the remote and thermal shutoff protection and identified shutdown stations until July 1, 2011. In that 8 year period we might save a catastrophe by the use of the remote shutoff and automatic thermal shutoff protection. We should leave this alone until after July 1, 2011.

This shall be retroactive to all internal valves required by the Code.Substantiation: 1. The location of the remote shutdown station is now dimensioned in the Code from the liquid transfer point, not from the internal valve. If the liquid transfer point is within 25 to 100 ft of the internal valve, the shutdown station could be placed at the internal valve, entirely defeating the purpose of the remote shutdown. 2. If a plant owner elects to update their tank valves by installing Emergency Shutoff Valves instead of internal valves, the location of the remote shutdown station is dimensioned (via 6.10.10(2)) from the ESV not the transfer point. For emergency response personnel, the expected location of shutdown stations should be consistent regardless of the type of valve selected. Also, shutdown stations for tank valves should not be required to be located at the existing location for bulkhead shutdown stations because this location may not be appropriate or practical for all plants.Committee Meeting Action: Accept in Principle Revise text to read as follows: 6.9.3 At least one remote shutdown station for internal valves in liquid service shall be installed not less than 25 ft (7.6 m) or more than 100 ft (30 m) from the liquid transfer point.

Consider accepting. STANNARD: The Committee action should have been to accept, if the Committee statement is to be believed. STOOKEY: The majority of the Committee chose to reject this item. The Committee should recognize that the proposed specification for the construction of vehicle impact protection originated in the 1988 edition of the Uniform Fire Code. This particular specification has been in use for over 15 years and was developed based on criteria developed by the California Fire Chiefs ̓Association-North Carolina Fire Prevention Officers. There is good experience with this particular design. NFPA 58 is currently silent on the issue of vehicle impact protection. The proposed language is in the Annex so the requirement is not mandatory. However, the Committee chose not to accept it. This is an interesting position given the Committeeʼs desire to avoid the application of professional engineering skills when a Product Release Prevention and Incident Preparedness Review (PRPIPER) is required (see item number 58-178, Log number 21). How can a design professional develop a design for vehicle impact protection when no criteria are given? The NFPA 58 committee as a majority embraces specification design for LP-Gas installations. This proposed vehicle impact protection design is no different._______________________________________________________________58-171 Log #159 Final Action: Accept in Principle( 6.22.4 )_______________________________________________________________Submitter: Samuel E.

(d) The incident preparedness review shall include an evaluation of the capabilities of plant personnel and local emergency response agencies to deal with probable emergency scenarios involving the installation. Wherever the term “incident prevention review” is used or proposed, revise it to read “incident preparedness review”.Substantiation: It is felt that the use of the word “preparedness” better describes the purpose of the review than does the word “prevention”. There is basic agreement with the explanation of the negative vote by Stookey. The proposed revisions are intended to deal with the need for AHJ review and approval, as well as the need for the evaluation of the capabilities of plant and local agencies that respond to emergencies involving the installation. The local fire department is included.Committee Meeting Action: Accept in Principle in Part Revise text to read as follows: 6.24.3 Protection of ASME Containers. 6.24.3.1 Fire protection shall be provided for installations with an aggregate water capacity of more than 4000 gal (15.1 m3) and of ASME containers on roofs.

Committee Statement: Portions of the proposal are accepted with editorial revisions. The name of the review is changed to reflect its intent. The proposed requirement of a PE to conduct the review was not accepted because it has not been demonstrated that a PE is required to conduct the analysis. The proposed last paragraph is not accepted because the subject is adequately covered in the Annex. Number Eligible to Vote: 30Ballot Results: Affirmative: 26 Negative: 1 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARDExplanation of Negative: STOOKEY: The actions taken by the majority of the Committee have avoided considering the capabilities or limitations of emergency responders. In many communities a bulk LP-Gas installation will be the greatest quantity of hazardous materials in a single location. If a location does not have a reliable water supply and water application by the local fire department cannot occur within a reasonable time period, then special protection is warranted. What constitutes special protection is the responsibility of the authority having jurisdiction and bulk plant owner. This is why subparagraph (d) was

448

58-42

Report on Comments — Copyright, NFPA NFPA 58 so important. The capabilities and limitations of emergency responders must be considered, especially in locations with complications such as no water supply, inadequate firefighter training, or inadequate apparatus capable of delivering a reliable fire flow are present. This section should have never been in the Annex. It is appropriate to make subparagraph (d) a minimum code requirement. This proposed change attempts to avoid the application of professional engineering skills when a safety analysis of bulk LP-Gas installations is required. NFPA 1 & NFPA 5000 authorize the code official to require the seal of a design professional. In the case of an Incident Action Plan or a Written Fire Safety Analysis, both attempt to explain a design and in some cases, certain assumptions will be made. Regardless of what you call the final report, when assumptions are made about designs, the AHJ can and should require a registered Professional Engineer to verify that the design and its assumptions have been examined and justified.Comment on Affirmative: BELKE: On this comment, I vote affirmative with a comment. I believe that the last sentence of the proposal (which would have required that the incident preparedness review include an evaluation of the capabilities of plant personnel and emergency responders to deal with probably emergency scenarios) should also have been accepted. The committee statement notes that the language is already in the non-mandatory appendix, but I would think it would be an important addition as a mandatory requirement.

_______________________________________________________________58-180 Log #46 Final Action: Accept in Principle in Part( 6.24.3.3 [3.10.2.2 a Old] )_______________________________________________________________Submitter: Denis Gagne, Eastern Propane and OilComment on Proposal No:58-77Recommendation: Revise paragraph 6.24.3.3 (subsection 3.10.2.2(a) in the 2001 edition) as indicated below: (a) A primary consideration in any such prevention review shall be an evaluation of the total product control system. , including emergency shutoff and internal valves equipped for remote enclosure and automatic shutoff using thermal (fire) actuation pullaway protection, and the optional requirements of Section 6.25, if used. Add an appendix item as indicated below: A.6.24.3.3: The requirements for appurtenances, including product flow control valves, on individual ASME containers of water capacity up to and including 4000 gallons are indicated on Table 5.3.4.1 (Table 2.3.3.2(a) in the 2001 edition). Appurtenances requirements on inlet and outlet connections of containers of size range 2001 to 4000 gallons and above 4000 gallons water capacity are stipulated in Tables 5.3.4.3 and 5.3.4.4 (Section 3.3.3.6 in 2001 edition). It is evident that for tanks of 2000 gallon water capacity no emergency shut off and internal valves or automatic shut off valves with thermal actuation pull-away protection are required. Installations with multiple containers of each less than 2000 gallon capacity are used for both vapor service and

liquid service. In general, multiple containers are manifolded on the vapor withdrawal side but are liquid filled individually. Where liquid withdrawal pipes from multiple ASME containers each of 2000 gallon or less water capacity are manifolded to a common header, an emergency shut off valve (with thermal actuation and manual shut off features) may be installed on the liquid withdrawal header, downstream and as close as possible to last container connection to the header. This will ensure that product flow is shut off even if the excess flow valves in the containers are not effective (due to low flow from each manifolded container). It is noted that for the size of the liquid filler nozzle used in containers of 1000-gallon capacity it is impractical to have an internal valve with an excess flow shut off feature. For specific requirements for internal valves refer to Section 6.9 and for emergency shut off valves see Section 6.10 (Section 3.2.18 and 3.2.19, respectively in the 2001 edition). Substantiation: The requirements of this paragraph are applicable to installations with an aggregate water capacity of more than 4000 gallons, irrespective of how those greater than 4000 gallons are achieved. For example, if an installation has five 1000-gallon tanks manifolded together it will come under the purview of this section. However, the requirements of the code as written at present, cannot be complied with because the individual 1000-gallon tanks do not have internal valves nor do they have (bulk head) shut off valves with pull away protection. Therefore, the code is requiring what is impossible to meet. Our recommendation is to move the rest of the language in Section 3.10.2.2(a) to an Appendix and include additional information on the types of valves and protection required for various size ASME tanks.Committee Meeting Action: Accept in Principle in Part Revise text to read as follows: 6.24.3.3 A primary consideration in any such incident prevention review shall be an evaluation of the total product control system, including emergency shutoff and internal valves equipped for remote closure and automatic shutoff using thermal (fire) actuation pullaway protection, where installed, and the optional requirements of Section 6.25, if used.

Distances for all underground and mounded ASME containers shall be measured from the relief valve and the filling connection container surface. No part of an underground or mounded ASME container shall be less than 10 ft (3.0 m) from a building or line of adjoining property that can be built upon, and no part of a mounded ASME container that is installed above grade shall be less than 5 ft (1.5 m) from a building or line of adjoining property that can be built upon.Substantiation: Distances for underground and mounded container should be measured from the tank surface to be consistent with measurements for aboveground containers. The installer will make these measurements during the installation process. The distances for underground and mounded containers have the same safety considerations for spacing to buildings and property lines. Under the present code wording, the mounded container could be closer to the building and would present a greater hazard than the underground. Making this modification to this section will provide for the same spacing for both styles of containers. The mounded tank in excess of 2001 water gal. would require earth cover which would slope to the building wall unless the mounded container is installed with a retaining wall. There are no facts that support a lesser distance for mounded containers than underground containers. The last part of this section causes confusion as one part of the code allows the measurements to be made from the filler and relief connections and the last part of the code does not permit any portion of the container to be less than ten ft. Under the first provision of the Code, a 108 in. diameter, 30,000 gal. water capacity mounded storage tank could have the shell of the container 6 in. from the building wall.Committee Meeting Action: Accept in PartCommittee Statement: The proposed reduction of the separation distance of mounded containers is not accepted because of the inherent difference in the installation of underground and aboveground, mounded containers.

Swiecicki, National Propane Gas AssociationComment on Proposal No:58-59Recommendation: Revise Committee Action as follows: (1) Insert a new 7.3.1.2(7): Exception No. 7: Venting of LP-Gas vapor utilized as the pressure source in remote shutdown systems for internal valves and emergency shutoff valves. (2) Insert a new (8) to section 7.3.1.2: (8) Venting of LP-Gas vapor utilized as the pressure source in remoteshutdown systems for internal valves and emergency shutoff valves shall bepermitted.Substantiation: There are numerous bulk plant installations in the United States that are successfully using LP-Gas vapor as a pressure source for activating remote shutoffs. Any pressure source offers different characteristics that must be considered in the design of a remote shut down system. LP-Gas is inexpensive, readily available, free of moisture and provides a reliable pressure source. When a remote shut down system utilizing LP-Gas vapor is properly designed, the system provides an equivalent level of safety to other pressure sources. The proposed system may also increase the level of safety by providing a reliable and readily available pressure source for activating the remote shutoffs. The proposed maximum tubing size has been increased from 1/4 in. to 3/8 in. OD to allow greater flexibility in system design. The quantity of gas released in the event of tubing failure is limited by an inlet orifice. The proposal allows the current systems that have been operating with no accident history to continue. Guidance for designing LP-Gas systems is provided in the appendix. The proposed guidance recognizes different environmental conditions that must be considered during the design phase of the system.

Fredenburg, North Carolina Dept. of Agriculture & Consumer ServicesComment on Proposal No:58-87Recommendation: Add the following text to Chapter 4: 7.4.4.3* When a container of less than 200 lb water capacity (84 lb propane capacity) is filled by a pump with a rated capacity of 20 gpm or more, proper filling level shall be verified by weight or bleed valve after the filling connection has been removed. Any overfill amount shall be removed from the container before the container is released to the consumer. If releasing the overfill amount, the release shall take place at a location at least 10 ft from a source of ignition and follow training guidelines for filling containers. Add the following text to Appendix A: A.7.4.4.3 Small volume containers can be easily overfilled by high volume pumps, even, in some cases, where a fill valve is equipped with a stop-fill or overfill prevention device. It is important to verify the amount of fuel in the container before it is released to the consumer when high volume pumps are used. If an overfill portion of LP-Gas must be released from the container, here are some suggestions for how and where to do it: 1. Remove the container to a location away from sources of ignition and gatherings of people. Use of the separation requirements in Section 3.2.2.2 are good guidelines for determining how far to remove the container. 2. If possible, use a cylinder purging facility with an elevated release point. 3. Take precautions to prevent liquid LP-Gas from touching skin, eyes, and other body parts.Substantiation: A form of this comment was presented as Proposal 58-87 (Log #32). It was rejected, with the committee statement being that “The proposed text does not add new requirements to the Code.” I disagree. The new requirement is that an additional step must be taken after the filling hose is disconnected to verify proper filing before the container is released to the customer when a high flow rate pump is used to fill a small container. Nowhere else I know of in the Code is there a requirement to verify proper filling after the filling hose is disconnected. Having watched the filling of many smaller containers, it is evident that the response of the operator is not always as quick as it should be. If the pump is a high volume pump and the container is small, it is very easy to not respond fast enough and the container becomes overfilled quickly. This requirement would make the operator perform an additional check of the container to

Report on Comments — Copyright, NFPA NFPA 58 verify that it is not overfilled, or if it is, to remove some of the fuel to make it safe. This problem was emphasized by an accident on August 9, 2001. A 9.9 gallon ASME tank mounted on a van was filled at a dispensing station. Since they had no meter on the dispenser, they used a bobtail to fill the tank. The receipt showed that they put 9.7 gallons into the tank, clearly an overfill for this tank. The tank was equipped with a stop-fill device and the operator assumed it had one and that it was working. After disassembling the tank fittings, we verified as much as we could that the stop-fill action was working. It appeared to be working, as it shut off flow when using air as the test medium and the float was manually moved to the full position. We checked with a manufacturerʼs representative for this valve and he stated that filling at high flow rate on this valve disables the stop-fill function. This is not an intended consequence, but it does occur. The manufacturer would not state what the maximum permitted flow would be to prevent disabling the stop-fill function. Many of these valves have been installed on small ASME tanks. The result of this overfill was the complete loss of the vehicle and all of the equipment in it, putting the owner out of business until another van could be bought and equipped. The next part of the substantiation is less supportable. Our inspectors have been told by propane company representatives that the OPDs are breaking and that they donʼt work at high flow rates. None of the dealers making the statement wanted to be identified. I saw some broken OPD valves that were about to be installed in cylinders until the break was discovered. The manufacturer claims that filling cannot occur if the valve is broken this way. If one manufacturerʼs valve can break this way, this and other manufacturerʼs valves can break in other ways that may not be fail safe. One manufacturerʼs representative told me he has heard of some off-shore OPD valves that are incapacitated by high flow rates. We have situations at state and county fairs where cylinders from 5 pounds propane capacity to 420 pounds propane capacity are filled by bobtails brought onsite to fill any container the customer presents for filling. Most companies allow the driver to fill these containers. The OPD should work on the smaller cylinders, but there is a concern filling 50 and 60 pound cylinders, those not required to have an OPD. If the cylinder is overfilled due to not having an OPD, or if the OPD malfunctions at the high flow rate, the consequences at the fairs can be significant as it could easily involve many people since the population density at fairs is very high. This new requirement would not prevent use of high flow rate pumps to fill small containers, it would only add a minor step to verify that overfilling has not occurred. This is a very small impact on the activities of a dispenser operator.Committee Meeting Action: RejectCommittee Statement: This concept was rejected at the ROP stage. The added sentence in the comment does not add a new requirement as the 10 ft distance exists in Chapter 6.

NFPA 5000 is an occupancy based building code. The proposed maximum allowable quantities only give guidance for three occupancies - so in the case of an assembly or institutional occupancy, this proposal offers no assistance in establishing indoor quantity limits for liquefied petroleum gases. The other problem is that the section titled storage has a parenthetical citation stating the units. The committee did not indicate the units of measurement in the proposal. One can interpret that the values shown in the table are 200 pounds while another may interpret 200 gallons.

Report on Comments — Copyright, NFPA NFPA 58 _________________58-215 Log #14 Final Action: Reject( 9-4.2.3 [6-3.2.2 Old] )_______________________________________________________________Submitter: Jim Griffin, Fisher Control International Inc.Comment on Proposal No:58-91Recommendation: I support code wording as presented in ROP 58-91. I would request that additional substantiation be added to ROP 58-91 for further clarification and reasoning for referring to the requirements of Section 2.4.5.4(1) and (2). The term “internal self-closing stop valve” is a term used by DOT, but is not defined in this code. The term “internal valve” is more technically accurate and should be used exclusively. The reference to Section 2.4.5.4(1) & (2) is necessary to clarify which method(s) of protection are provided by the Internal Valve in order to “protect” the hose. NFPA 58 9.4.2.3 has never required and should not require the internal valve excess flow function to provide hose protection as there are too many restrictions between the excess flow and the hose that will make excess flow closure an unreliable protection in this application. The addition of these paragraph clarifications result in the same level of protection that was required by the term “Internal Self Closing Stop Valve” in the 2001 edition and by “Emergency Valves” in 1998 and early editions of NFPA 58 for this paragraph which did not require excess flow function.Substantiation: • The reference to Section 2.4.5.4(1) and (2) is necessary to clarify what method(s) of protection are provided by the Internal Valve to “protect” the hose. NFPA 58 9.4.2.3 has never required excess flow closure to provide hose protection. Further reasoning is provided below. • NFPA 58, paragraph 9.4.2.3 tries to define the “protection” afforded a hose by valve terminology and not by describing the features needed to protect the hose. Users must look at the valve definition to determine the features that are supposed to “protect” the hose. Technically, no valve can protect (or as the dic tionary states “...defend, guard from attack, ...cover or shield from injury or danger”) the hose from damage, deterioration, overpressure or failure. What the valve can do is shut off the flow of product to the hose in the event that the pressure integrity of the hose is compromised. Using the term “internal valve” without restrictions adds new code requirements (excess flow function) which will not always activate to “protect” the hoses. Realistically, an excess flow located in the bottom of the tank can not be relied upon nor should it be expected to provide reliable closure in the event of hose separation or loss of pressure integrity. There are too many restrictions between the internal valve and the hose to make excess flow closure a reliable protection feature. • From about 1976 through the 1998 edition of this paragraph, an “Emergency Valve” defined the features desired. These features are found in 1.7.71.1 and 2.4.5.4. These features are summarized here as “Thermal Actuation”, “Manual Shutoff from a Remote Location”, and “Manual Shutoff at the Installed Location”. The most important part of the listed features is that excess flow protection is not included. In the wisdom of the original drafters to the first edition of this paragraph, they did not require excess flow protection because of the many system restrictions between an excess flow valve or function incorporated into an internal valve and the hose make it almost impossible for flow rate to exceed the excess flow closing rate. • However, the LP-Gas industry does not use an Emergency Valve on Cargo Tank Vehicles. Therefore, in the 2001 edition, “Emergency Valve” was replaced with the DOT terminology of “Internal Self-Closing Stop Valve”. But there is no definition in NFPA 58 for “Internal Self-Closing Stop Valve”. By DOTʼs definitions, an Internal Self-Closing Stop Valve does not have an excess flow feature or function, but it does include the same features as described in 1.7.71.1 and 2.4.5.4 for an Emergency Valve. So technically, there was no change in the code. However, the LP-Gas industry did not recognize this new valve terminology. • An Internal Valve is defined in 1.7.71.4 and includes the same features as found in 1.7.71.1 and 2.4.5.4 PLUS “excess flow function:. By definition then, if we define “protection” as being afforded ay an Internal Valve, we have added a new code requirement (excess flow) for the hose. In reality, the pump, meter, piping size changes, variations in inlet pressures, etc. found between the internal valve (including the excess flow function) and the hose will in most cases restrict flow to less than the required flow rate to activate the excess flow function in the internal valve. Therefore, without closure because of the many restrictions in the system, no “protection” is afforded the hose. It is these system features that make the excess flow function unreliable and an inappropriate choice for protecting the hose. For further explanations to excess flow limitations refer to NPGA 113 “The Limitations of Excess Flow Check Valves for LP-Gas” and to Fisherʼs Internal Valve Instructions Manuals.Committee Meeting Action: RejectCommittee Statement: The comment does not make a specific proposal as required in the NFPA Regulations Govern Committee Projects.

Acceptable code wording is presented in ROP 58-92 (9.4.2.3) (Log #63), which I support.Substantiation: • The root problem with 9.4.2.3 is that NFPA 58 tries to define the “protection” afforded the hose by valve terminology and not by describing the features we want.

For further explanations to excess flow limitations refer to NPGA 113 “The Limitations of Excess Flow Check Valves for LP-Gas” and to Fisherʼs Internal Valve Instruction Manuals. • The substantiation for ROP #91 is incorrect. The use of an internal valve to protect a hose is not part of the DOT code as negotiated in DOT HM225A. In fact it is contrary to what was agreed to in the negotiations between DOT and the industry. If ROP #91 were accepted into NFPA 58, it would directly conflict with the CFR49 code changes agreed to in HM225A. Considerable time was spent in the negotiations explaining to DOT that an excess flow valve could not be expected to function in the event of a hose failure. In HM225A, the protection afforded to a liquid hose separation is in the form of a “Passive Shutdown System” for transports and an “Off Truck Remote Shutdown System” for bobtail trucks. Not excess flow function. • One of the results of HM225A negotiations was to clarify CFR 49 code language as to the function that an excess flow valve, function or feature could provide in a Cargo Tank Vehicle, which is only shear protection at the outlet of the excess flow valve. The current CFR 49 code does not rely on excess flow equipment to stop the flow of product in the event of the loss of pressure integrity to the hose or for hose separation. • ROP #63 is acceptable because it defines {reference to 2.4.5.4(1) and (2)} in the code, those internal valve functions, that the code is relying upon to “protect” the hose. And more specifically, that protection is defined by those features in the internal valve that can used with confidence to shut off the flow of product upon the loss of pressure integrity in the hose whether it be a small leak or complete hose separation.Committee Meeting Action: Accept in PrincipleCommittee Statement: The committee thanks Mr. Griffin for his support of the committeeʼs action on proposal 58-92, however the statement provided in the comment goes well beyond the committeeʼs reason for rejection of the proposal, which was not to reprint DOT requirements in NFPA 58.Number Eligible to Vote: 30Ballot Results: Affirmative: 27 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARD

_______________________________________________________________58-238 Log #211 Final Action: Accept in Principle in Part( 11.3.3.2 )_______________________________________________________________Submitter: Samuel E. McTier, McTier Supply Co. / Rep. NPGAComment on Proposal No:58-1Recommendation: Revise text to read as follows: 11.3.3.2 Field welding on containers shall be limited to attachments to nonpressure parts, such as the following saddle pads, wear plates, lugs, and brackets installed by the container manufacturer. (A) Saddle pads (B) Wear plates (C) Lugs (D) Brackets installed by the container manufacturer 11.3.3.3 Containers showing excessive denting, bulging, gouging, or excessive corrosion exceeding limits established by the code of manufacture shall be removed from service.Substantiation: Correction to 11.3.3.2 says the same thing and is just as easy to read and saves about an inch of vertical space. Paragraph 11.3.3.3 is revised to make it the same as 5.2.1.11. There are many redundant paragraphs in Chapter 11 by design. Committee Meeting Action: Accept in Principle in Part 1. Revise 11.3.3.2 by substituting “nonpressure containing” for “nonpressure” 2. Revise 11.3.3.3 by deleting “excessive”.Committee Statement: The commenter is correct that this paragraph and 5.2.1.11 were identical in previous editions and should remain so. The committee will review the matter in the next edition. Reference to the code of manufacture is not accepted as the committee is advised that the ASME code does not contain limits of denting, bulging, gouging and corrosion.Number Eligible to Vote: 31Ballot Results: Affirmative: 26 Negative: 1 Vote Not Returned: 4 KASTANAS, REZA, ZEPP, WARDExplanation of Negative: GILBERT: I have studied the task force recommendations of the comments submitted for re-ballot and I agree with the task force recommendations on all items except item #18. 2. Revise 11.3.3.3 by deleting “excessive”. Comment: I realize that the word “excessive” is a subjective term that will not be eveny applied by everyone. but including this term is indicative that we are willing to accept an allowable amount of denting, gouging and corrosion. I do not want to be placed in a situation where we will not allow any amount of denting, gouging or corrosion (Iʼll agree to a prohibition of any bulging).

The items listed in series in the recommended version are all installed by the manufacturer and it so states. The recommended change in the Preprint version lists the items vertically which takes up valuable space with no increase in clarity. In fact, it is less clear as the phrase “installed by the manufacturer” as written in the Preprint only applies to the brackets which is inaccurate as it applies to all of the items; therefore, it should be changed. There is a “typo” in 11.3.3.3. The phrase “exceeding limits established by the code of manufacture” was deleted earlier in 5.2.1.1; therefore, it should have

been deleted in this comment rather than added. It should read as follows: “11.3.3.3 Containers showing excessive denting, bulging, or excessive corrosion shall be removed from service.” The Committee should reverse its action and approve the revised version of the comment as it does improve clarity in 11.3.3.2 and corrects 11.3.3.3.Explanation of Abstention: STANNARD: See my comment on 58-66 (Log #76).

_______________________________________________________________58-258 Log #27 Final Action: Accept( 11-14 [8-6 Old] )_______________________________________________________________Submitter: Bruce J. Swiecicki, National Propane Gas AssociationComment on Proposal No:58-106Recommendation: Make no revisions to the text.Substantiation: In response to the request of the NFPA Technical Committee on LP-Gas regarding the action taken on Proposal 58-106, the National Propane Gas Association offers the following for the consideration of the committee.

The current requirements of NFPA 58, and revisions already in progress for the 2004 edition of NFPA 58, do provide protection for propane fuel containers used on vehicles, including school buses. The committee made a revision to 8.2.3 (g) (Proposal 58-103) to enhance the integrity of all propane engine fuel systems. This change will require a valve in the liquid outlet connection of a propane engine fuel container, which is actuated both manually and automatically when the engine is not in operating mode, independent of the ignition switch position. This new requirement is in addition to the requirement for an excess flow valve in the liquid outlet of the vehicular propane container. In implementing this additional requirement the committee recognized that excess flow valves could not be relied upon to stop flow in all accident conditions. It must be noted that a propane engine fuel container is an ASME pressure vessel that provides a significantly greater level of protection than the tanks used for liquid fuels on vehicles (including school buses). ASME containers in propane service are required to have a design pressure of 250 psi. ASME containers in propane service as vehicular fuel containers are required to have a design pressure of 312 psi, a 25% increase in working pressure with a corresponding increase in shell thickness. The ASME code requires a design margin of 3.5, providing additional container thickness. In addition, the cylindrical shape of an ASME propane engine fuel container provides additional ability to withstand damage. Liquid fuel containers are thin wall vessels designed to contain the liquid only. Where installed on vehicles, they require protection not needed for propane containers. In contrast, as noted above, propane containers used on school buses for engine fuel applications have significant crash-worthiness due to their design characteristics. There have been crash tests of propane fueled vehicles that have confirmed an adequate level of protection exists in the case of an accident. A series of propane fueled bus tests was conducted by the Netherlands Organization for Applied Technical Research (TNO). A report issued in 1983 described four city bus crash tests that resulted in only one instance of a minor leak. It is noted that the leak was in the liquid outlet valve, which is addressed in the revision made to the 2004 edition of NFPA 58. In addition, TNO conducted tests involving propane fueled automobiles, showing only minor leakage following head-on and rear end crashes at 50 – 60 km/hr (31 – 37 mph). While these tests were conducted under conditions not as serious as the school bus incident investigated by NTSB, they do show a high level of safety in vehicle propane fuel container installations. Drop tests have been conducted by the propane industry on engine fuel tanks. In one series of tests, plastic gasoline tanks, steel gasoline tanks, and steel propane tanks were filled to their maximum permitted filling level and were dropped vertically from a height of 30 feet onto a steel plate mounted on a concrete slab, with the tanks striking the plate at varying angles. Both the plastic and steel gasoline tanks released their entire liquid contents upon impact and the steel propane tanks retained their contents with no leakage. The National Propane Gas Association will review any new information that becomes available on the subject.

4.0 FERROUS MATERIALS

4.1 Temperature Sensitive Materials

This section addresses steels - wrought and cast, including irons and martens-itic stainless steels which exhibit a loss in toughness and usable engineering properties as the temperature is lowered.

Most steels in this group are subjected to a decrease in toughness as the service temperature goes below -20oF. For usage below -200F, a reduction in allowable material stress in required to preclude the need for impact testing of these materials kin order to certify them for usage at these lower than -20oF service temperatures.

All weld and braze joints for these materials are similarly subjected to these lower temperature requirements. Structural steels are subjected to these require-ments.

NEW- Additional Limitation for Carbon Steel Pipe

1. The wall thickness for propane piping (Carbon Steel material classifica-tion Type P-1 with SMYS between 20 - 35 ksi) NPS 4 and smaller shall be Schedule 40 pipe. (ED - This allows usage down to -55oF without any impact

The application of welding or threading does not affect the low temperature restrictions) If thicker pipe (heavier pipe schedule), the system loses its flexibility and requires stress reductions be employed as its service temperature goes below -200F.

4.2 Temperature Insensitive Materials - Cast and Wrought, Ferrous and non-Ferrous

This section addresses both wrought and cast ferrous alloys which are suitable fur usage at temperatures down to -45oF and further, such as:Specially processed carbon and low alloy steels, Nickel Steels, Austenitic, Ferritic and Duplex Stainless SteelsHigh nickel - iron alloys, such as Invar, Aluminum and its alloys,Coppers, copper nickels, brasses, bronzes, beryllium coppers, Nickel and nickel alloys.

4.3 LISTING OF SUITABLE MATERIALS FOR LP SERVICE - FERROUS

The present ferrous materials listed in NFPA 58 all have a lower allowable temperature service limit of -200F.

The following tables address that limitation and greatly expand the allowable materials for -20oF and below. The usage of ASTM A53 - Type F piping is prohibited.

If ferrous piping is Classification P1 and has a SMYS range between 20 - 35 ksi and is 4-Inch NPS and less and is Schedule 40 or less, there is no usage restriction down to -55oF. (RAH- Note - all steel piping presently listed in NFPA 58 meets this requirement.)

Structural Welding

All welding of low-temperature sensitive ferrous materials for structural rea-sons and whose failure would affect the integrity of the piping or LP tankage / tankage support system shall be done by welders qualified to ASME IX of the B&PV Code or AWS-D1.1

The resulting weld joints shall be subjected to the same requirements as the material.

The minimum design material temperature shall be the governing factor. If the weld joint could be subjected to the –20oF to –50oF environment and the mate-rial being welded is a temperature sensitive ferrous material which is being used below its normal minimum design temperature, i.e., below –20oF, but above –50oF, then the joint shall be subjected to impact testing if the applied stress is greater than 70% of the allowable material stress “S” per the appli-cable governing design code or derated so it doesnʼt exceed the 70% allowable material stress level (S).

Oxy-fuel welding shall be prohibited from all applications that are to be used or installed in any LP-Gas facility.

Appendix – Oxyfuel welding in carbon steel is known to result in lower toughness welds when compared to current welding technology. For this reason it is being eliminated from this Standard.

13.5.2 Visual Inspection. Visual inspection shall be performed by a person who is qualified in welding inspection, is familiar with welding workmanship, and can review drawing requirements to determine what the finished welded product should be.

That person shall, on an audit basis, witnesses the fit-up, the welding process, and review the finished weld for conformance to good engineering practice or applicable engineering drawing and prepare a written report documenting those observations.

13.5.2 Brazing All brazing shall be in accordance with ASME B&PV Section IX. All brazing alloys shall be listed in SFA5.8 of ASME-Section IIC or AWS-A5.8 and shall have a melting point that exceeds 1000°F (538°C).

13.5.3 Soldering

(a) Soldering shall not be used on liquid, vapor or vent lines or product con-tainment surfaces where failure would result in product release.

(b) Soldering shall be permitted for hermetic or environmental sealing purposes, where the integrity or operational capability of the component is not detrimentally affected by the loss of solder joint because of unexpected heating.

(c) All solder alloys shall be listed in ASTM-B32 - Standard Specification for Solder Metal.

13.5.4 Bolting. All new and replacement bolting which is not part of a vendor approved or recommended component for LP service shall comply with Grade B-7 bolts in accordance with ASTM-A193 - Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for High-Temperature Service. Impact tests shall not be required for bolting material conforming to ASTM A193, Grade B-7, for use at temperatures above -50 ºF.

If the intended area of service in the facility cannot reach the -50oF for any pro-cess upset or environmental condition, then this requirement is not applicable.

All new and replacement ferrous (non stainless steel) bolting and washers shall be plated for corrosion protection.

13.5.5 Other Mechanical Connections Other connections, such as flaring, compression fittings, etc. shall be approved for use in LP systems and shall be

rated for the design pressure where the component is being used. If that is not known, the fitting shall be rated for 1250 psi.

9.0 CORROSION - DESIGN WORDS

3.2.15.7 Aboveground piping shall be supported and protected against physi-cal damage by vehicles. The portion of aboveground piping in contact with a support or a corrosion-causing substance shall be protected against corrosion.

3.2.15.9 Underground metallic piping shall be protected against corrosion as warranted by soil conditions (see 3.2.24).


13.7.0 CORROSION PROTECTION

A-13.7.0 The following paragraphs clearly direct that corrosion protec-tion is of paramount importance in an LP-Gas plant and systems. Since LP-Gas itself is not corrosive, the fluid is considered a normal fluid for corrosion pur-poses and ASME B31.3 data. Therefore, the ASME design allows the selection of a wall thickness based on the absence of any corrosion deterioration – from interior LP-Gas contact and exterior, from external environmental conditions. The exterior environmental corrosion must therefore be controlled.

Report on Comments — Copyright, NFPA NFPA 58 Substantiation:

1. Deletion of 2.4.4.3(c) (3):Some propane vapor systems being installed require pipe sizes larger than 2”. Three-inch pipe is used quite often and 4-inch pipe is not a rarity. 2.4.4.3 (3) sets the requirements for compression type mechanical fittings for polyethylene piping. ASTM D 2513, Standard Specification for Thermoplastic Gas Pressure Pipe, Tubing and Fittings is that requirement.

When the allowed use of polyethylene compression type mechanical fittings was first included in NFPA 58, the 2-inch IPS size fittings were the largest size that were approved, marketed and manufactured. Since that time, both 3-inch and 4-inch IPS size fittings that meet the requirements of Category 1 of ASTM D 2513 are being manufactured, marketed and safely used. 2. Changes to 3.2.15.1 and 3.2.15.3:This proposal implements the formal interpretation of December 8, 1995, and provides clear directions for welded and brazed piping systems. NFPA formal interpretation 95-2 reads:

Reference: 3.2.15.1

Question No. 1: Is it the intent of NFPA 58, 3.2.15.1 to apply to welded piping only?Answer: Yes. When the current 3.2.15.1 was added to the standard in the 1995 edition, the committee discussions were centered on concerns over welding quality, and the addition was intended to pro-vide standards for welding.

Question No. 2: Is it the intent to classify LP-Gas as a normal fluid when using ASME B 31.3?Answer: YesIssue Edition: 1995Reference: 3-2.15.1Issue Date: December 8, 1995Effective Date: December 28, 1995

Considering the above interpretation, all the requirements of B31.3 no longer belong in 3.2.15.1. The use of qualified personnel performing welding and brazing, the inspection of the processes, and the examination of welds will ensure joint quality.

3. Endorsement of the Technical Committee Action to Reject the Proposal

The NPGA supports the action of the Technical Committee to reject Proposal 58-137. The following analysis provides further substantiation for that action.

Next, a line-by-line compare the proposal to the current requirements was made. This was difficult because the proposal did not use legislative text to identify existing existing requirements had not been referenced or deleted and the content had been re-ordered with new requirements mixed in.

For example, an analysis of the proposed sections on corrosion produced the following (comments are indicated):

13.4.4 Stainless Steel Piping, Components and Fittings. Stainless steel piping, components and fittings shall not be buried without corrosion protection. (Comment: Section 3.2.24 requires ALL metallic equipment and components to be protected.)

13.5.4 Bolting. All new and replacement bolting shall comply with Grade B-7 bolts in accordance with ASTM-A193 - Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for High-Temperature Service. Impact tests shall not be required for bolting material conforming to ASTM A193, Grade B-7, for use at temperatures above -50 ºF.

All new and replacement ferrous (non stainless steel) bolting and washers shall be plated for corrosion protection. (Comment: New Requirement)

13.7.0 CORROSION PROTECTION

A-13.7.0 The following paragraphs clearly direct that corrosion protection is of paramount importance in an LP-Gas plant and sys-tems. (Comment: Language not consistent with Manual of Style for Standards) Since LP-Gas itself is not corrosive, the fluid is consid-ered a normal fluid for corrosion purposes and ASME B31.3 data. Therefore, the ASME design allows the selection of a wall thick-ness based on the absence of any corrosion deterioration – from interior LP-Gas contact and exterior, from external environmental conditions. The exterior environmental corrosion must therefore be controlled.

13.7.2 LP-Gas systems and facilities shall be protected from atmo-spheric and water-based corrosion, including galvanic or dissimilar metals corrosion, atmospheric and faying surface (surfaces in close contact with each other that may be exposed to water or moisture contact) corrosion. (Comment: Based on 2nd sentence of 3.2.24 “Corrosion protection of all other materials shall be in accordance with accepted engineering practice.”)

13.7.3 All aboveground surfaces that are subject to natural deterio-ration shall be protected. (Comment: 3.2.4.4 requires above ground containers to be painted. 3.2.15.7 requires portion of aboveground piping in contact with a support or a corrosion-causing substance to be protected. 3.8.2.8 references 3.2.15 and indicates exposed piping should be protected and includes vehicle piping. 8.2.8.6 indicates exposed piping should be protected.)

A-13.7.3 This may consist of painting in accordance with the Steel Structures Painting Council (SSPC) guidelines for steel surfaces or otherwise protecting the surfaces by preventing moisture contact. (Comment: Reference to SSPC guidelines is new. Reference to cur-rent A3.2.4.4 (light colors) is missing.)

13.7.4 All buried, mounded, or otherwise below-surface compo-nents shall be protected from corrosion. (Comment: 3.2.9.1(h), 3.2.9.2(a), 3.2.9.3(d), 3.2.15.9, 3.2.16.3, 3.2.16.10 (details missing), 3.2.24, 3.10.3.2, 3.10.3.3)

(a) Ferrous materials shall be protected in accordance with NACE RP-01-69. (Comment: From A3.2.24 – Reference incorrect. Should be NACE RP0169-02)

(b) All buried ferrous components shall be both coated and have an impressed cathodic or sacrificial anode protection system applied. Appropriate test stations shall be installed to verify the operability of these cathodic protection systems. (Comment: NEW REQUIREMENT)

13.7.5 No metallic material shall be direct buried. All burying or mounding shall be in accordance with NACE RP-01-1969. (Comment: Same as 13.7.4? – why repeated?)

13.7.6 Non-ferrous materials installed underground shall be protect-ed from underground corrosion by the installer. This includes, but is not limited to, the valves, fittings, regulators installed in the dome of a buried container and piping. (Comment: Same as 13.7.4? – why repeated?)

A-13.7.6 The corrosion protection of any buried or below-grade component is of paramount importance.

(Comment: Items that currently appear in NFPA 58 but are omitted from the proposal:

• Corrosion protected enclosure for connections for pres-sure relief valves on containers (2.2.3.5)

• Nameplate corrosion protection on containers (2.2.6.3)• Corrosion protection for part of container in contact with

saddles or foundations or masonry (3.2.6.4)• Corrosion protection for valves per 3.2.24 (2.4.5.5,

3.2.16.15, 6.3.3.1)• Corrosion protection for wire braid on hose, hose con-

nections and flexible connectors (2.4.6.1)• Details of enclosing polyethylene piping in gas tight fit-

tings protected from corrosion (3.2.16.10)• Specific references that exposed vehicle piping be pro-

tected (3.8.2.8 and 8.2.8.6))

The analysis of the welding sections was prepared in a slightly different format, where CAPITAL LETTERS were used to highlight differences between the proposed Chapter 13 and the existing NFPA 58. The analysis is as follows:

Those areas which are new requirements, such as the –50° temperature require-ment, were more difficult to document. In trying to determine the validity of this new requirement, the following are some of the items that were investi-gated:

• The Charpy impact test and reliance on it was developed prior to the availability of fracture mechanics theory.

• The nuclear industry addressed this problem back in the early 80ʼs with regard to stress fractures from liquid nitrogen at -200° F (much colder than LPG). They developed computer programs to do the design analysis, using fracture mechanics theory, that are now com-mercially available.

• ASME B31.4 – Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids specifically addresses brittle and ductile fractures propagation (cold temperature fractures) for carbon dioxide piping – but NOT for LPG (402.5), although LPG piping is clearly addressed by the Standard. Carbon dioxide flashes at a much colder temperature than LPG.

One standard used by the European Pressure Equipment Directive in the evaluation of pressure vessels, which includes LP-Gas vessels, is EN1252-2:2001 - Cryogenic vessels - Materials - Part 2: Toughness requirements for temperatures between -80C and -20C. It is not consistent with the proposal contained in 58-137.

NPGA was also concerned about developing new, unsubstantiated requirements for existing technologies. There is an international emphasis on harmonization, therefore, mandating that existing standards be reviewed and considered before new requirements are developed.

There was not sufficient time to read all of the standards, worldwide, on the topics in the proposed Log #86. There are many international standards that have a bearing on the materials and equipment used in the propane industry. Though too numerous to list here, the list of such standards is available from NPGA.

Standards were obtained and read, and details were noted where inconsisten-cies were present with Log #86. Many such inconsistencies were present and NPGA has developed a list of them for just one comparison between the proposal 58-137 and ASME B31.4 – Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids. Too voluminous to include here, it is available from NPGA staff should the need arise to review it. The analysis clearly indicates that it was not always obvious where the requirements in the proposal 58-137 originated. The process of analyzing where the requirements came from and whether any proposed changes were reasonable and necessary has been ongoing.

Unfortunately, due to the time frame within which NPGA has had to respond on this issue and the enormous amounts of material that need to be reviewed to substantiate the necessity and validity of proposed changes, we have only been able to complete two areas of the proposal that we believe are ready for inclu-sion in NFPA 58. Those proposals are for Joining and Polyethylene Pipe.

These are proposed above for your review. NPGA is committed to continuing to work through this proposal, document the existing versus proposed changes, and develop alternate proposals, on an issue-by-issue basis. Separate task force groups will probably be necessary to tackle the larger issues. We are confident that the NFPA Technical Committee on Liquefied Petroleum Gases recognizes the need to document and understand new requirements prior to adopting them and will continue to work with us to ensure that NFPA 58 continues to safe-guard the public.

Committee Meeting Action: Accept in Principle in Part 1. Accept item number 1. 2. Do not accept the deletion of item number 2, and revise 6.8.3.1 as follows: 6.8.3.1 All metallic LP-Gas piping shall be installed in accordance with ASME B 31.3, Process Piping or Section 6.8. Committee Statement: Item 1 recognizes that compression fitting for larger sizes of plastic pipe are availible and are being used. Item 2, as revised, provides a clear alternate for installers. The remainder of the proposal is incomplete and would leave omissions in the Code.Number Eligible to Vote: 30Ballot Results: Affirmative: 27 Vote Not Returned: 3 BOGOSIAN, KASTANAS, WARD
