B. New NFPA Document Revision Process (Attachment A)

C. Revision Cycle Review and timeline (Attachment B)

5. New Business

A. Review of Public Input (Sent under separate cover)

B. Formal Interpretations (FIs). NFPA policy regarding FIs has changed. FIs cannot be renewed for subsequent editions. The committee must review the FIs issued for the 2014 edition (Attachment C) and take appropriate action. The committee is

required to create First Revisions or Committee Inputs to address the FIs by section 6.6 of the Regulations Governing the Development of NFPA Standards.

C. Conflict between 6.4.3.2 and 6.4.1.2. In the last revision cycle, renumbering resulted in subsection 6.4.3 becoming independent of the underground containers subsection, resulting in it being applicable to all containers. This created an internal conflict between 6.3.4.2 and 6.4.1.2. The committee should determine appropriate action to resolve this conflict.

D. Report of the Editorial Task Group. B. Swiecicki (chair); R. Hoffmann; S. McTier; L. Woodward. The Editorial Task Group recommendations are included in Attachment D.

E. Conflict between Table 6.5.2.1 and Table 8.4.1.2 column (5). Table 6.5.2.1 requires that points of transfer be located at least 10 ft from containers other than those being filled. Table. 8.4.1.2 has graduated distances required between cylinders and dispensing stations based on how much LP-Gas is in storage. The committee should review the two sections and take appropriate action.

F. Security and Accessibility. Committee member Richard Fredenburg has requested that the committee review of 5.7.8.1(F) and 6.19.4, specifically related to the use of locked gates that prevent “ready access” to control valves on containers during normal and emergency operations.

G. Hot Air Ballooning. A Formal Interpretation (FI) request was received by NFPA asking if ground operations associated with hot air ballooning (i.e. ground transportation and filling of cylinders) is excluded from NFPA 58 by 1.3.2(7). The FI cannot be processed because the committee has never discussed the topic. The FAA “Approved Parts List” permits cylinders with international markings that are not recognized by NFPA 58. The FAA Balloon Flying Handbook permits filling of cylinders installed in hot air balloons by volume. The committee should determine if ground operations related to hot air ballooning is under the scope of NFPA 58 or take appropriate action to clarify 1.3.2(7).

6. Old Business - S. Gentry Information Request. Mr. Gentry requested information regarding the shipping and handling of propane as a refrigerant. Mr. Lemoff indicated that when (9) was added to the code, it was the intent of the committee that NFPA 58 would continue to cover handling and container construction requirements. Mr. Gentry requested committee members to research the application and consider whether additional requirements or special connector requirements should be developed for this application.

7. Other Items?

8. Date/Location of Next Meeting. (The next meeting must take place between May 15 and Oct 30, 2015.)

9. Adjournment.

Chapter 15 Pipe and Tubing Sizing Tables Delete “Undiluted” in front of “Propane” in the Sizing Tables’ “Gas” titles. Substantiation:There is a new docket on this issue as commercial propane is diluted with other hydrocarbons as shown in ASTM D 1835. As this table was from NFPA 54, their committee was probably concerned about propane-air systems. We do not address propane-air systems in NFPA 58. Figure A.6.3.1.1 Change “1000 gal (3.8 m3 ) tank” to “1000 gal (3.8 m3 ) container” in five places. FIGURE I.1(a) Change “bulk truck” to “cargo tank vehicle” in drawing and in Note 2. FIGURE I.1(b) Add “Nearest line of adjoining property that can be built upon” to the property line that is shown on the drawing

3.3.25 (New) Fixed Piping System. Piping, valves, and fittings permanently installed in

a location to connect the source of the LP-Gas to the utilization equipment.

Substantiation: This definition is needed because the term “fixed piping system” is used

throughout the code and it is not clearly understood what is meant by it.
