AGENDA — NFPA 30 First Draft Meeting

NFPA 30 Technical Committee on Tank Storage and Piping Systems

National Fire Protection Association Quincy MA

Thursday, August 30, 2012, 1:00 PM to 5:00 PM

1. Call to Order. 2. Introduction of Attendees. Update of Committee Roster. [Attachment № A1] 3. Approval of Minutes of Last Meeting. [September, 2010, Rosemont IL]

[Attachment № A2] 4. Report of Committee Chair. 5. Report of Staff Liaison.

Technical Committee Scope. [Attachment № A3] Technical Committee Membership Status.

- Bud Slye has resigned from the Technical Committee. - Steve Haines has been recommended for the Chair position. - Special enforcer Emphasis Program. - Alternate Member Emphasis Program. - Balance of Interests. [Attachment № A3]

Document Revision Schedule for Annual 2014 Cycle. [Attachment № A4] 6. Member Reports on Current Issues . [As Necessary] 7. Review and Act on Public Input Proposed Amendments to NFPA 30-2012. [Attachment № A5] 8. Recent Correspondence.

Letters from CSB Recommending: - fully automated level control systems for storage tanks - enhanced protection from trespass for isolated tanks

9. Old Business.

Emergency Vent Reduction Factors – Reformat as Table. [Attachment № A6] Should Chapter 22 require special grounding provisions for aboveground storage tanks

located in areas protected by an impervious liner? Should 22.4 include separation distances from the tank shell to a rail siding that routinely

has tank rail cars thereon?


Should the shell-to-shell spacing provisions of Table 22.4.2 apply to tanks installed inside a building under the scope of Chapter 24?

Should Chapter 24 apply to any tank in any building? Should its scope speak to “storage tank buildings” and “storage tanks inside buildings”? Tanks installed per NFPA 30A, NFPA 31, and NFPA 37 would be exempt.

Should Chapter 24 specify a minimum sprinkler density at the ceiling? NFPA 13 would probably call for Extra Hazard Group 2.

10. New Business.

Should Chapter 21 contain an exemption for liquids with flash points, but no fire points? Subsection 21.7.1.5: Revise to require only one of the three options. Section 22.4: Add statement that a multi-compartment tank is treated the same as a single

compartment tank for purposes of siting. In 22.7.3.4, should “M” be defined as the “relative molecular weight of the vapor being

relieved”? Should Chapter 23 mandate that all pipe risers and vent pipes be electrically bonded and

grounded? [based on recent explosion incidents involving lightning strikes at underground storage tanks]

Situation: underground tank located on one side of a building and supplying fuel to a stationary engine on the other side of the building. Can piping be run through the basement?

Chapter 25: revise Scope to include Class III liquids. Subsection 25.13.1 conflicts with 27.8.2.6/7 for Class II and Class III liquids. Section 27.4: does it apply to all valves, regardless of whether they connect to the top of

the tank or below the liquid level? Paragraph 27.4.4.1(1): What is the criteria for “resistant to fire”? Equivalent to steel? Should not the provisions of 27.8.2.3 through 27.8.2.12.1 apply to aboveground tanks as

well as underground tanks? [from Jeff Shapiro] Subsection 28.4.1: Clarify to indicate these are fixed unloading stations. What is

appropriate distance for “direct transfer from tank vehicle to storage tank”? 11. Schedule Next Meeting(s). 12. Adjournment.

5. The Staff Liaison reported on the following:

Scopes of Technical Correlating Committee and Technical Committees. The Technical Committee agreed that the Committee scope is in need of change and directed the Staff Liaison to proceed with same.

Membership Status. The Staff Liaison reported on recent changes to committee membership and on the balance of interests on the committees.

Document Revision Schedule for NFPA 30-2012. The Staff Liaison reviewed the deadlines in the revision schedule for NFPA 30-2012.

6. There were no current issues to report to the Technical Correlating Committee. 7. The Technical Committee reviewed and took action on all public comments on the Report on

Proposals (ROP) for the 2012 edition of NFPA 30 that were received on those chapters of NFPA 30 within the Technical Committee’s jurisdiction. No correlation issues were evident. The Staff Liaison was directed to proceed with the letter ballot for the Report on Comments to NFPA 30-2012.

8. There was no recent correspondence requiring the Technical Correlating Committee’s attention. 9. Under “Other Old Business, the Technical Committee agreed that the emergency venting reduction

factors needs to be reformatted as a table. 10. Under New Business, the Technical Committee identified the following areas worthy of attention in

the future:

Devise a flowchart for Chapter 21 to assist users in proper application of the various storage tank chapters.

Does Chapter 22 need special grounding provisions for aboveground storage tanks located in areas protected by an impervious liner?

Should 22.4 include separation distances from the tank shell to a rail siding that routinely has tank rail cars thereon?

Should the shell-to-shell spacing provisions of Table 22.4.2 apply to tanks installed inside a building under the scope of Chapter 24?

Should Chapter 24 apply to any tank in any building? I.e., should its scope speak to “storage tank buildings” and “storage tanks inside buildings”?

Should Chapter 24 specify a minimum sprinkler density at the ceiling? NFPA 13 would probably call for Extra Hazard Group 2.

Should there be a chapter on special applications, e.g., storage tanks that supply fuel to stationary engines?

Should Section 22.12 address installation of pumps within the diked area? Is there a need for guidance / good practices on remotely controlled tank farms and pumping

stations? Can an emergency vent of a tank inside a building discharge inside the building? Need for a Task Group to address special requirements for skid-mounted emergency

generators/fuel tank combinations. 11. The Technical Committee deferred planning for the next meeting cycle until the production of the

2012 edition of NFPA 30 is completed. 12. The meeting adjourned at 10:05 AM.

_______________________________________________________________________________________________Richard S. Kraus, API/Petroleum Safety Consultants

Revise text to read:21.7.1* Prevention of Overfilling of Storage Tanks. Facilities with aboveground tanks larger than 1320 gal (5000 L)

storing Class I or Class II liquids shall establish procedures or in accordance with API 2350 Overfill Protection forStorage Tanks in Petroleum Facilities and shall provide appropriate equipment, or both as needed, to prevent overfillingof tanks.

To assist users in establishing an overfill protection program (OPP) in accoprdance with API 2350.(Copyright Note: API 2350 is already incorporated into NFPA 30 by reference). The change also provides for eithersystems or equipment (where needed) to comply with the requirements.




Revise text to read:21.7.1.1 Facilities with aboveground tanks that receive and transfer Class I liquids from mainline pipelines or marine

vessels shall establish and follow formal written procedures in accordance with API 2350, to prevent overfilling of tanks utilizing one of the following methods of protection:

API 2350 now contains a new chapter covering overfill prevention process (OPP) requiring formalmanagemant systems to better protect from overfills.

movement of fire-fighting personnel and fire protection equipment.The deleted text does not explain for what purpose the aisle serve and how they should be arranged.

The annex text points to NFPA 101 on design etc of aisles and the proposed text move that requirement to the body ofthe code for clarification.



_______________________________________________________________________________________________Scott J. Harrison, Marioff Inc.

Revise text to read as follows;24.6.2.3* Where the need is indicated by the hazards of storage or exposure as determined by 21.6.3, fixed

protection shall be required utilizing approved foam, foam-water sprinkler systems, sprinkler systems, water mistsystems, water spray systems, deluge systems, gaseous extinguishing systems, dry chemical extinguishing systems,fire-resistive materials, or a combination of these.

All other forms of fixed fire protection systems are listed except “water mist systems”. This is anaccepted, approved and listed form of fire protection that should be included in this list.If proposal 24.6.2.3* is accepted, to be consistent with the standards listed, a reference to NFPA 750, Standard on

Water Mist Fire Protection Systems should be included in this annex section. NFPA 750 is a performance basedstandard allowing the engineering, design and installation of an equivalent fixed fire protection system providingprotection suited to the need indicated by the hazard. NFPA 750 should be indicated to direct an AHJ, engineer,designer or end-user to this standard as an option.




Add new text to read as follows:(9) NFPA 750,

Add an entry for NFPA 750, Standard on Water Mist Fire Protection Systems. Since all other firecontrol systems are listed and NFPA 750 is missing, it should be added to the list. NFPA 750 is a performance basedstandard allowing the engineering, design and installation of an equivalent fixed fire protection system providingprotection suited to the need indicated by the hazard. NFPA 750 should be indicated to direct an AHJ, engineer,designer or end-user to this standard as another option.



_______________________________________________________________________________________________Wayne B. Geyer, Steel Tank Institute (STI/SPFA)

Add new text to read as follows:Emergency vents on protected aboveground tanks complying with UL 2085 containing Class II and Class III

liquids are allowed to discharge inside the building.UL 2085 protected aboveground tanks are designed and constructed to withstand a two-hour fire test

of 2000°F during which no single point temperature may exceed 400°F and the average temperature rise throughout theinternal tank can be no greater than 260°F. Given the stringent testing requirement, activation of the emergency vent islikely only under extreme fire conditions over an extended period of time. Further, NFPA 30 requires that emergencyvents placed on vent pipes that extend beyond twelve inches from the tank be reengineered to account for the potentialback pressure and ensure activation at the appropriate pressure. It is not unusual to see vent lines extending 30 or 40feet or more through a building in order to achieve the exterior discharge. Allowing the emergency vent to dischargeinside eliminates the need to reengineer the venting and ensures proper sizing and activation of the emergency vent.




Revise text to read: A.21.7.4.1 For further information, see API 2015, and API 2015A, A Guide for

Controlling the Lead Hazard Associated with Tank Entry and Cleaning; and API 2015B, Cleaning Open Top andCovered Floating Roof 2016, .

API 2015A and 2015B are no longer in publication or use. The information provided in thesedocuments is not provided in API 2016.




Revise text to read as follows:A.24.6.2.3 See NFPA 13,

NFPA 15, and NFPA 16,for information on these subjects.

For certain fuel types, such as ketones, esters, and alcohols, the minimum required densities established in the listingcriteria for foam discharge devices are often higher than the general densities specified for protection of flammable andcombustible liquids. When determining the design criteria for extinguishing systems using foam, it is important to ensurethat the listing criteria, which are typically based on empirical data from fire tests, are not overlooked. Otherwise, the fireprotection system design can be inadequate for proper protection.

All other forms of fixed fire protection systems are listed except “water mist systems”. This is anaccepted, approved and listed form of fire protection that should be included in this list.If proposal 24.6.2.3* is accepted, to be consistent with the standards listed, a reference to NFPA 750, Standard on

Water Mist Fire Protection Systems should be included in this annex section. NFPA 750 is a performance basedstandard allowing the engineering, design and installation of an equivalent fixed fire protection system providingprotection suited to the need indicated by the hazard. NFPA 750 should be indicated to direct an AHJ, engineer,designer or end-user to this standard as an option.


Replacement for 22.7.3.5 Reduction Factors for Emergency Relief Venting

22.7.3.5 For tanks containing stable liquids, the required emergency relief venting capacity determined by 22.7.3.2, 22.7.3.3, or 22.7.3.4 shall be permitted to be multiplied by one of the reduction factors shown in Table 22.7.3.5 when protection is provided as indicated. Only one reduction factor shall be used for any one tank. Protection measures shall meet 22.7.3.5 (1) through (4), as appropriate. (1) Drainage shall meet the requirements of 22.11.1 and the reduction factor shall only be applicable to tanks with wetted area greater than 200 ft2 (19 m2). (2) A manually actuated water spray protection system shall meet the requirements of NFPA 15, Standard for Water Spray Fixed Systems for Fire Protection and shall include drainage that meets the requirements of 22.11.1. (3) An automatically actuated water spray system shall meet the requirements of NFPA 15, Standard for Water Spray Fixed Systems for Fire Protection. (4) Tank shell insulation shall meet the requirements of 22.7.3.8. 22.7.3.5.1* Water-miscible liquids whose heats of combustion and rates of burning are equal to or less than those of ethyl alcohol shall be allowed an additional 50 percent reduction in the required emergency relief venting capacity, as given in the appropriate column of Table 22.7.3.5. Drainage shall not be required to obtain this reduction. In no case shall the combined reduction factor be less than 0.15. There shall be no fire exposure from liquids other than from those liquids covered by this provision. 22.7.3.5.2* Liquids whose heats of combustion and rates of burning are equal to or less than those of ethyl alcohol (ethanol), but are not water-miscible shall be allowed an additional 50 percent reduction in the required emergency relief venting capacity, as given in the appropriate column of Table 22.7.3.5. No further reduction shall be allowed for protection by means of water spray. [Needs to be explained!] Drainage shall not be required to obtain this reduction. In no case shall the combined reduction factor be less than 0.15. There shall be no fire exposure from liquids other than from those liquids covered by this provision.
