This list represents the membership at the time the Committee was balloted on the text of this edition. Since that time, changes in the membership may have occurred.

Committee Scope: This Committee shall have primary responsibil- ity for documents on safeguarding against the fire and explosion hazards associated with the storage, handling, and dispensing of flammable and combustible liquids at automotive and marine service stations and with related activities such as lubrication, minor repairs, adjustments, and routine maintenance work.

The Report of the Technical Committee on Automotive and Marine Service Stations is presented for adoption.

This Report was prepared by the Technical Committee on Automottve and Marine Service Stations and proposes for adoption amendments to NFPA 30A-1993, Automotive and Marine Service Stations Code. NFPA 30A-1993 is published in Volume 2 of the 1995 National Fire Codes and in separate pamphlet form.

This Report has been submitted to letter ballot of tile Technical Committee on Automotive and Marine Service Stations which consists of 28 voting members; of whom 25 voted affirmatively, 1 abstained (Mr. Garlatti), and 2 ballot(s) were not returned (Messrs. Cunningham and Perkins).

Mr. Garlatti voted to abstain due to prior commitments and new job assignment that required relocation, and was not able to adequately review proposals.

The following two comments were received with affirmative votes:

Mr. Magera submitted the following comment on Proposal 30A-51 (Log #43): "The intent of the submitter as clearly stated in the original

proposal was that the valve stabilizer bar be mounted directly into the concrete foundation OR securely affixed to a dispenser mounting frame. The phrase "independently of the dispenser" adds unnecessary confusion since it couldbe interpreted to mean "independent of the dispenser mounting frame," which was not the intent of the submitter. The phrase should be dropped."

Mr. Bendle (/kit. to Mr. Davidson) submitted the following comment on Proposals 30A-50 (Log #16) and 30A-51 (Log #43): "I object to the literal translation of the verbiage regarding Logs 16

and 43. The emergencyvalve needs to be secured per the manufacturer's instructions and design so that it functions properly. The proposed verbiage is based on unreasonable restriction of competition, in my opinion."

(Log #44) 30A- 1 - (1-1.1): Accept in Principle SUBMITTER: Steven R. Shinners , Yellow Freight System, Inc. RECOMMENDATION: Revise text as follows:

"This code shall apply to automotive and mar ine service stations, service stations located inside buildings and fleet vehicle fueling facilities." SUBSTANTIATION: Many of the p resen t restrictions of NFPA 30A were directed toward public service stations d ispens ing Class I liquids. Non-public fuel ing facilities do not have the fire exposures that are i nhe ren t with public a t t ended and non-a t t ended service stations, I.E. Flammable fuels vs. combust ible fuels and fuel ing will be done by t ra ined employees vs. una t t ended publ ic fueling. A separate reference to fleet vehicle fuel ing facilities should be made. COMMITrEE ACTION: Accept in Principle.

Revise 1-1.1 to read: "This code shall apply to automotive service stations, mar ine service

stations, service stations located inside buildings, and fleet vehicle service stations." COMMITTEE STATEMENT: The Technical Commi t tee agrees with the in tent of this proposal and does include specific provisions for fleet refueling. Tbe Technical Commit tee wishes to keep the language consistent.

(Log #25) 30A- 2 - (1-1.3): Reject SUBMITTER: Rick Thornberry , ConVanlt RECOMMENDATION: Revise text to read as follows: ,1-1:3 This code shall !~ot app!y to fuelin.g facilities

on farms, in rural areas, and at isolated construct ion sites and isolated ear th-moving nroiects including gravel nits, ouarr ies and borrow nits. when such fa~cilities are ner~n~ltted by tbe '~uthori ty having iurisdiction to comolvwi th NFPA'395. S tandard for the Storage of Flammable and'C~ombustible Liouids at Farms and Isolated Sites. SUBSTANTIATION: NFPA 30A does no t properly correlate with the scope of NFPA 395-1993, Standard for the Storage of Flammable and Combust ible Liquids at Farms and Isolated Sites. In fact, it could be in terpre ted tha t NFPA 395 could no t be used for the storage of f lammable and combust ible liquids used to fuel motor vehicles at such locations based on the provisions in Section 1-1.2(a) of NFPA 395 without any correlative changes made to the NFPA 30A Scope wltich presently does not exempt farms and o ther isolated sites except for large off-the-road ear thmoving and construct ion vehicle locations. This p roposed revision to file scope of NFPA 30A will also provide some relief to the more restrictive provisions of NFPA 30A in those locations where the authori ty having jurisdict ion does no t d e e m it necessary to comply with tile more restrictive

, provisions because the hazard is reduced and isolated in accordance with NFPA 395. COMMITrEE ACTION: Reject. COMMITTEE STATEMENT: This subsect ion was not in t ended to apply to small tanks governed by NFPA 395. It was added to the 1990 edition of NFPA 30A to address larger tanks that otherwise were installed in accordance with NFPA 30. This would confuse these latter facilities with small ( m a x i m u m capacity: 1100 gallons) tanks at farms, etc. Also, the Technical Commit tee points out that NFPA 395 is being incorpora ted into NFPA 30 and NFPA 30 does include the appropriate language to correlate with NFPA 30A.

(Log #CP14) 30A-3- (1-2 Combust ible Liquid, Flammable Liquid): Accept SUBMITTER: Technical Commit tee on Automotive and Marine Service Stations RECOMMENDATION: After the definit ions of "Combustible Liquid" and "Flammable Liquid", add tile following parenthetical:

"(See Append ix B for informat ion about typical liquids f ound at service stations." SUBSTANTIATION: This provides the user with a reference to useful informat ion tha t is to be added to a new append ix being added to NFPA 30A by means o f ano the r proposal. COMMITTEE ACTION: AccepL

(Log #13) 30A- 4 - (1-2 Dispensing Device, Dispensing Device, Overhead Type (New)): Accept in Part SUBMITTER: Martin E. Magera, Underwri ters Laboratories Inc. RECOMMENDATION: Add new text:

Dispensing Device. Typically, a single enclosed assembly of electrical componen t s and fluid conf ining parts in tended to transfer fuel f rom one storage container to another , or f rom a storage conta iner to the fuel tank of a motor vehicle or self-propelled crate

Dispensing Device, Overhead Type. A dispensing device that may consist of one or more individual units in tended for installation in conjunct ion with each other, m o u n t e d above an automotive service station forecour t typicallywithin the service station canopy structure, and characterized by the use of an overhead hose reel.

NOTE: The above definit ion dist inguishes between Overhead Type Dispensing Devices and convent ional Dispensing Devices wbich may include integral co lumns and canopies and which may have the d ispens ing hose outlets located at the top of the dispenser enclosnre.

OR NOTE: The above definit ion dist inguishes between Overhead

Type Dispensing Devices and Dispensing Devices which may include integral co lumns and canopies and which may have the d ispensing hose outlets located at the top of the d ispenser enclosure. Such bigb hose units are to be treated as conventional Dispensing Devices. SUBSTANTIATION: The references to Overhead Type Dispensing Devices were added to the NEC in 1971 (See 1971 NEC 514-2e) in anticipation of the distribution of a d ispensing system m o u n t e d in and suspended f rom an overhead service station canopy. The references were eventually adop ted into NFPA 30A, but this unique dispensing system has yet to be marke ted in the U.S. Since Overhead Type is no t clearly defined, some authorit ies have assumed incorrectly that the te rm refers to high hose mult i -product dispensers, and this has resulted in a good a m o u n t of confusion in the field. The proposed definitions are in t ended to minimize this confusion. COMMITrEE ACTION: Accept in Part.

Accept only the definit ion of "Dispensing Device, Overhead Type", but replace "may consist" with "consists" and replace " m o u n ted above.. .forecourt" with "moun ted above a d ispensing area".

Add an appendix i tem to read: "This definit ion dis t inguishes between an overhead dispenser that

uses a retractable hose on an overhead reel and the now-common dispensing device that has one or more hose outlets located in a canopy at the top of the dispensing device. These "high-hose" units, also called "mult i-product dispensers," are treated by NFPA 30A as conventional d ispensing devices."

Do no t accept notes. COMMIT'FEE STATEMENT: The Technical Commit tee does not feel that the te rm "dispensing device" requires definition. All o ther cbanges are to effect clarity.

(Log #26) 30A- 5 - (1-2 Enclosed Secondary Conta inment , Protected Aboveground Tank (New)): Reject SUBMITTER: Rick Thornberry , ConVault RECOMMENDATION: Add the following new definitions:

Enclosed Secondary Conta inment : A liquid-tight enclosure des igned to provide supplementa ry con ta inmen t of the contents of an above g r o u n d storage tank by completely enclosing the tank so as to create an interstitial space capable of being moni to red for a leak in the tank; which is no t open to the a tmosphere except for normally closed open ing provided for emergency venting, inspec- t ion and leak detection.

Protected Aboveground Tank. A storage tank assembly co n s i s fn g of an aboveground storage tank encased by construct ion providing fire-resistive protection to the tank and its contents f rom a high- intensity liquid pool fire and protect ion of the tank f rom physical damage.

Also, delete the definit ion for Fire Resistant Tank. SUBSTANTIATION: The proposed definit ion for "Enclosed Secondary Conta inment" is necessary in order to allow the use of enclosed secondary con ta inmen t within the s tandard as it relates to p roposed requi rements for protected aboveground tanks which are in a compan ion proposal to revise Section 2-4.5. This definit ion describes the attributes believed necessary to indicate what enclosed secondary con ta inmen t is.

The definit ion for "protected aboveground tank" is based on a similar definit ion conta ined in Appendix II-F of the 1994 Uni form Fire Code. This definit ion is being provided so that protected aboveground tanks can be recognized in NFPA 30A an d appropriate

460

N F P A 3 0 A - - A 9 6 R O P

criteria established for their use. Compan ion proposals have been submi t ted to revise various sectiqns of NFPA 30A to recognize and regulate protected aboveground tanks.

The defini t ion for "FireResis tant Tank" is p roposed to be dele ted since it would no t be n e e d e d if the definit ion for "Protected Aboveground Tank" is accepted. Fire resistant tanks are a subset of protected aboveground tanks.

Protected aboveground tanks achieve a h igher level of fire safety and overall protect ion compared to that for fire resistant tanks. The major differences are ms follows. The tempera ture limits on file pr imary tank are m u c h lower for protected aboveground tanks in order t o p r e v e n t the anto-ignit ion of the tank contents. The p ro t ec t edaboveg round tank is also subjected to a hose s t ream test at the end of the fire test. Additional criteria are provided for vehicle impact protect ion and ballistic impact protection which are not a part of file listing for fir(: resistant tanks. A protected aboveground tank provides the h ighes t level of fire safety for the category of aboveground tanks used in accordance with NFPA 30A. COMMITTEE ACTION: Reject. COMMITrEE STATEMENT: This proposed definit ion correlates with Proposal 30A-26 (Log #34). Since Proposal 30A-26 (Log #34) was not accepted, there ~s no need for dais definition.

(Log #4) 30A- 6 - (1-2 Fire Resistant Tank): Reject SUBMITTER: Jon v. Brannan , Underwri ters Laboratories, Inc. RECOMMENDATION: Revise text as follows:

Fire Resistant Tank. A listed tank assembly that provides fire resistive protection f rom exposures to a high intensity liquid pool fire (see 24.5) . SUBSTANTIATION: 1. The Fire Resistive Tank ~ should be listed no t necessarily jus t tile aboveground tank conta ined within the insulation system. In many cases, the primary tank may no t be a separately listed aboveground tank as now required.

2. Would allow for a non-metal l ic aboveground tank encased within an insulation system that provided protection f rom exposure to a high intensity liquid pool fire. COMMITrEE ACTION: Reject. COMMITrEE STATEMENT: It was never this Technical Commi t t ee ' s in ten t tha t the entire assembly be listed, only the primary (liquid holding) vessel.

(Log #10) 30A- 7 - (1-2 Fire Resistant Tank): Accept SUBMITTER: Jon V. Brannan, Underwri ters Laboratories, Inc. RECOMMENDATION: Revise text to read:

Fire Resistant Tank. A Listed Aboveground Tank tha t provides fire resistive protection f rom exposures to a high intensity liquid pool fire (see 2-4.5). SUBSTANTIATION: I The Fire Resistant Tank assembly should be Listed as a uni t and no t necessarily jus t the aboveground tank conta ined within the insulat ion system. A Listing of the Fire Resistant tank would indicate that the 2 h r fire exposure was covered as part of the Listing a long with o ther requi rements for Aboveground Storage Tanks.

2. A Steel Aboveground Tank conta ined within an insulation system, to provide a 2 hr fire rating, may not and in all probability will no t be ~ Listed as required b y t h e cur rent definit ion unde r Section 1-2.

3. Would allow for a non-metal l ic Aboveground Tank encased within an insulat ion system that provides protect ion f rom exposure to a high intensity liquid pool fire. COMMITTEE ACTION: Accept.

(Log #45) 30A- 8 - (1-2 Fleet Vehicle Fuel ing Facility (New)): Accept in Principle SUBMITTER: Steven F~ Shinners , Yellow Freight System, Inc. RECOMMENDATION: Add new definit ion as follows:

Fleet Vehicle Fueling Facility. A fueling facility, including dispensers and storage tanks, at which fuel ing is l imited to vehicles in the service of the opera t ing entity(ies) occupying the premises, with addit ional access restricted to author ized vehicles and visitors. SUBSTANTIATION: Many o f the present restrictions of NFPA 30A were directed toward pnblic service stations d ispensing Class 1 liquids. Non-public fuel ing facilities do no t have the fire exposures

that are i nhe ren t with public a t t ended and non-a t t ended service stations, I.E. Flammable fuels vs. combust ible fuels and fueling will be done by t ra ined employees vs. una t t ended publ ic fueling. A separate reference to fleet vehicle fueling facilities should be made. COMMITrEEACTION: Accept in Principle.

Refer to Commit tee Action on Proposal 30A-9 (Log #CP1). COMMITTEE STATEMENT: The in tent of this proposal is me t by the definit ion drafted by the Technical Commit tee . This latter is more accurate and more consistent with the language now in NFPA 30A~

(Log #CP1) 30A-9 - (1-2 Fleet Vehicle Service Station (New)): Accept SUBMITI'ER: Technical Commit tee on Automotive and Marine Service Stations RECOMMENDATION: Add a new definit ion as follows:

Fleet Vehicle Service Station. Tha t por t ion of a commercial , industrial, governmenta l , or manufac tu r ing property where liquids used as fuels are s tored and d ispensed into the fuel tanks of motor vehicles that are used in connect ion with such businesses, by persons within the employ of such businesses. SUBSTANTIATION: This definit ion is necessary to allow NFPA 30A to properly address refueling of fleet vehicles. COMMITrEE ACTION: Accept.

(Log #40) 30A- 10 - (2-1.1 (d), 9-3.5): Reject SUBMITTER: Rick Thornberry , ConVault RECOMMENDATION: Delete Section 2-1.1 (d) in its entirety. Also delete Section 9-3.5. SUBSTANTIATION: This section has been used inappropriately to allow unpro tec ted steel tanks in close proximity to buildings, property lines, and public ways. However, this was no t the in tent of dais section when it was first incorporated into this s tandard. The key to this section is the r equ i r emen t for a "listed tank system" which was based on a manufac tu re r o f a n aboveground tank assembly provided with a water jacket to give it a degree of fire resistive protect ion who was to obtain a specific listing for this in t ended purpose. However, that listing was never obta ined and, therefore, no specific pe r fo rmance criteria were established to imp lemen t dais part of the section. Fur thermore , new Section 2-4 adequately covers the installation o f a b o v e g r o u n d storage tanks. A compan ion proposal which has been submi t ted on behal f of ConVault to revise Section 1-1.3 will address tank installations at farms and isolated sites to allow the use of unpro tec ted steel tanks when permi t ted by the authori ty having jurisdict ion. Delet ing this section simplify the use of this s tandard and el iminate the potential for the misapplication of this section which circumvents the requi rements of Section 24. COMMITrEE ACTION: Reject. COMMITrEE STATEMENT: The Technical Commit tee has de t e rmined tha t existing "9-3.5" systems can remain in service. The submit ter provides no justification tha t use of such systems to date has posed problems.

(Log #27) 30A- 11 - (2-1.1(g)): Reject SUBMITTER: Rick Thornberry , ConVanlt RECOMMENDATION: Revise text to read as follows:

(g) A b o v e . r o u n d storage tanks located ~Lv.~ ~ . . . . . d at au tomo- tive service s~tations with tThe approval of the authori ty having jurisdict ion ~ d a~ v ' ,,v~d~d ,%; in accordance with Section 2-4. SUBSTANTIATION: This proposed change accomplishes two things. First, it clarifies that this section applies to aboveground storage tanks ra ther than tanks located aboveground since one m e t h o d of installation includes aboveground storage tanks located within below grade vaults. Second, it clarifies that the approval of the authori ty having jurisdict ion is to be in accordance with Section 2-4 ra ther than a blanket approval for any type of installation.

Ano the r compan ion proposal revises Section 2-4.1 to clarify how the authori ty having jurisdict ion makes his approval of the aboveground storage tank installation at automotive service stations in his jurisdiction. This allows the authori ty having jurisdict ion to de te rmine which type of aboveground storage tank installation he will allow in his jur isdict ion once he decides to allow such installa- tions. As presently s t ructured Section 2-1.1 (g) only gives the authori ty having jurisdict ion the option to allow aboveground

461

N F P A 3 0 A - - A 9 6 R O P

storage tank installation is acceptable should he chose to allow aboveground storage tanks. This is a subtle but significant differ- ence in concept. Some authorities having jurisdiction have been reluctant to approve the use of above ground storage tanks in accordance with Section 2-4 since they believed they did not have the option of limiting the application of Section 2-4 to the type of aboveground storage tank installation they believe to be acceptable for their jurisdiction. COMMI'['rEE ACTION: Reject. COMMITrEE STATEMENT: This proposal offers no improvement over the current text. The existing language is clear.

(Log #46) 30A- 12 - (2-1.3): Reject SUBMITTER: Steven R. Shinners, Yellow Freight System, Inc. RECOMMENDATION: Revise text as follows:

"Aboveground tanks located at a Bulk Plant, storing Class I liquids, shall not be connected by piping to service station tanks. Aboveground tanks located a a Bulk Plant, storing Class II and IlIA liquids, may be connected by piping to other dispensing tanks located at fleet vehicle fueling facilities." SUBSTANTIATION: Large fleet vehicle fueling facilities require bulk storage and dispensing of Class II and IIIA liquids into motor vehicle tanks. The code should allow for direct dispensing from Bulk Plants, storing Class II or IliA liquids, into motor vehicle tanks or connection to a smaller "Day Tank' for dispensing into motor vehicle tanks. Paragraph 2-1.7 provides protection of fuel flow between Bulk Plant tanks and dispensing or day tanks. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: Subsection 2-1.3 does not apply to fleet vehicle refueling. Nothing in NFPA 30A prohibits what is proposed by the submitter.

(Log #CP11) 30A- 13 - (2-3.2): Accept SUBMITTER: Technical Committee on Automotive and Marine Service Stations RECOMMENDATION: Replace the words "Table 7" with the words "Chapter 7". SUBSTANTIATION: Editorial clarification. COMMITTEE ACTION: Accept.

(Log #GP10) 30A- 14- (2-4 Title): Accept SUBMITTER: Technical Committee on Automotive and Marine Service Stations RECOMMENDATION: Delete the word "Automotive" from the title of this section. SUBSTANTIATION: This section applies to any aboveground tank used within the scope of NFPA 30A. COMMITrEE ACTION: Accept.

(Log #28) 30A- 16- (2-4.1): Reject SUBMITTER: Rick Thornberry, ConVanlt RECOMMENDATION: Delete the sentence contained within parentheses and relocate to Appendix A as a new Section A-2-4.1:

2-4.1" Except as modified by the provisions of this section, aboveground storage tanks shall comply with the applicable provisions in Chapters 2 and 3 of NFPA 30, Flammable and

Ve'~:,-l,- Fu,AI.,~, v; 6,;d,.~ k,,%i ,i~,,d6,, 6i~ thls ~ubjcc~.) SUBSTANTIATION: This sentence only provides information and is not enforceable. Thus, it belongs in Appendix A. By accomplish- ing this proposed revision, this sections will also be brought into compliance with BOCA's policy on standards. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The document referenced, PEI RP200, is the only document that provides any guidance for installation of aboveground tanks and fueling systems. It is referenced here in such a manner that it is clear the reference is not mandatory. The Technical Committee notes that many NFPA documents have similar references.

(Log #29) 30A- 17- (2-4.1 (New)): Reject SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Add a new Section 2-4.1 to read as follows and renumber the remaining sections accordingly.

2-4.1 Approval Required. With the specific approval of the authority having jurisdiction, aboveground storage tanks shall be permitted to be located at automotive service stations in accordance with this section. The authority having jurisdiction shall determine which type of aboveground storage tank installation regulated by this section shall be permitted. SUBSTANTIATION: The purpose of this proposal is to give the authority having jurisdiction the ability to approve the particular type of aboveground storage tank installation he believes to be acceptable for use in his jurisdiction. As presently structured, once the authority having jurisdiction approves the concept of allowing aboveground storage tanks at automotive service stations, he does not have the authority to limit the type of aboveground storage tank that can be used as long as it meets the requirements of Section 2-4. This proposal gives him that authority so that he will not be reluctant to approve the use of aboveground storage tanks at automotive service stations when he has the ability to control the

~yp e of aboveground storage tank installation in his jurisdiction ased on the requirements in Section 2-4. This new section also provides charging language to indicate that

aboveground storage tanks at automotive service stations are required to comply with the requirements of Section 2-4 when they are allowed in accordance with the approval of the authority having Jcurisdiction.

OMMITrEE ACTION: Reject. COMMITTEE STATEMENT: The Technical Committee notes that NFPA 30A specifically intends to provide alternative means to provide aboveground storage at service stations. To accept this proposal would negate the flexibility originally intended by the Teclmical Committee.

(Log #22) 30A- 15 - (2-4.1): Reject SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Revise text to read as follows:

and Combustible Liquids Code excent as modified herein. (PEI RP200-92, Recommended Practices for Installation of Aboveground Storage Systems for Motor Vehicle Fueling, provides information on this subject.) SUBSTANTIATION: This proposal provides charging language that clearly indicates aboveground storage tanks are required to comply with Section 2-4 and Chapter 2 and 3 of NFPA 30 as modified by Section 2-4. COMMITI'EE ACTION: Reject. COMMITTEE STATEMENT: This proposal offers no improvement over the current language.

(Log #30) 30A- 18 - (2-4.1.2 (New)): Reject SUBMITTER: Rick Thornberry, GonVault RECOMMENDATION: Add a new Section 2-4.1.2 to read as follows:

2-4.1.2 Aboveground storage tanks shall be installed in vaults in accordance with 2-4.4 or shall comply with the requirements for

~ rotected aboveground tanks in 2-4.5. UBSTANTIATION: The purpose of this proposal is to limit the

use of aboveground storage tanks at automotive service stations when approved by file authority having jurisdiction to either tanks installed in vaults or protected aboveground tanks. This will eliminate the use of unprotected aboveground steel tanks which are presently permitted based on separation distances greater than those allowed for tanks in vaults or fire resistant tanks in accordance with Section 2-4.2.2. A companion proposal to Section 1-1.3 will allow the use of

unprotected aboveground steel tanks on farms, in rural areas, in isolated construction sites and isolated earth-moving projects such as gravel pits, quarries, and bottom pits when approved by the authority

462

N F P A 3 0 A ~ A 9 6 R O P

having jur isdict ion and they comply with NFPA 395, S tanda[d for the Storage of Flammable a n d Combust ible Liquids at Farms and Isolated Sites. We believe that the only appropria te allowable use for unpro tec ted aboveground steel storage tanks for fueling automotive motor vehicles is within the scope of NFPA 395 and not NFPA 30A.

It is unrealistic to expect that increased separat ion distances will provide adequate fire safety for up to 40,000 gal of Class I liquids s tored in unpro tec ted aboveground steel s torage tanks. The separat ion distances in Section 2-4.2.2 may be adequate for property protect ion and the prevent ion of exposure f r e s and exposure to the public, bu t they do not solve the p rob lem of fire f ighter safety. W h e n an aboveground rank becomes involved in a fire, the local fire d e p a r t m e n t will a t t empt to ext inguish that fire. Thus , die fire d e p a r t m e n t is at risk and is exposed to the unpro tec ted steel tanks involved in fire. Should the emergency vent no t operate properly or it be locked down for some reason, there is a high probability that the tank may explode and endange r the lives of the fire fighters. COMMITTEE ACTION: Reject. C O M M I T r E E STATEMENT: This proposal correlates with Proposal 30A-26 (Log #34). Since Proposal 30A-26 (Log #34) was not accepted, there is no need for this new requirement . Also, i twas the specific intent of the Technical Commit tee to allow the opt ion of a traditional abovegrouncl storage tank for these systems.

(Log #31) 30A- 19 - (2-4.2.1): Reject SUBMITTER: Rick Thornberry , ConVault RECOMMENDATION: Revise text to read as follows:

2-4.2.1 Tanks s tor ing (3lass I and Class II liquids at an individual site shall be limited to a m a x i m u m individual capacity of 12,000 gal (45,600 L) and aggregate capacity of 407000 48 000 gal (152,~00 L) ( 182,400 L). SUBSTANTIATION: This change will allow a total of four 12,000 gal tanks instead of four 10,000 gal tanks or three 12,000 gal tanks and a 4,000 gal tank. This allows for more economical fuel deliveries without a significant increase in the fire hazard. C O M M I T r E E ACTION: Reject. C O M M I T r E E STATEMENT: Tile m a x i m u m aggregate capacity of 40,000 gallons tha t is now established by paragraph 2-4.2.1 was deliberately chosen so ~-s no t to exceed the 42,000 gallon capacity that would trigger implementa t ion of file U.S. Environmental Protection Agency 's Spill Prevention Control and Counte rmeasures rules for u n d e r g r o u n d tanks. The Technical Commit tee did not want to see die provisions of 2-4.4 used as a means of avoiding compliance with these federal requirements .

(Log #47) 30A- 20 - (2-4.2.1): Accept in Part SUBMITTER: Steven R. Shinners , Yellow Freight System, Inc. RECOMMENDATION: Revise text as follows:

"Tanks storing Class I and Class II liquids at a service station shall be limited to a m a x i m u m individual capacity of 12,000 gal (45,600 L) and an aggregate capacity of 48,000 gal (182,400 L). Tanks storing Class II and Class IlIA liquids at a fleet vehicle fuel ing facility shall be limited to a m a x i m u m individual fueling capacity of 20,000 ~ (76,000 L) and an aggregate capacity of 80,000 gal (304,000 L)."

BSTANTIATION: The fire exposure is m u c h less than service stations where Class I fuel is d ispensed by the public. Utilizing larger individual tanks allows fleet fuelers to eliminate multiple tanks where applicable. Larger aggregates should be allowed due to Class II and Class IIIA liquid restrictions. NFPA 30 also increases property line and bui lding set backs for tanks based on tank capacity. COMI~f lTrEEACTION: Accep t in Part.

SUBStI'ANTIATION: Tiffs proposal is based on a compan ion proposal tha t revises Section 2-4 to limit its application to tanks installed in vaults or protected aboveground tanks. The proposed reduct ion in separat ion distances is based on relating the separation distances to Table 2-6 in NFPA 30-1993. The distances in that table which vary in accordance with the capacity of the tank have been doubled on tile assumpt ion that the i nhe ren t fire resistive protection

~ rovided by tanks in vaults or protected aboveground tanks should e adequate to allow reduced separat ion distances which still

provide a 100 percent safety factor above the separat ion distances allowed for unpro tec ted aboveground storage tanks.

It is also interest ing to compare these separat ion distances to those specified in Table 2-1 of NFPA 30. ff tile tank is provided with an approved inert ing system or an approved foam system, the m i n i m u m distances specified in Table 2-6 for an unpro tec ted aboveground storage tank can be reduced in ha l l Certainly, the hazard repre- sented by aboveground storage tanks is greater at automotive service stations than at tank storage facilities where the public does riot generally have access. This justifies some increase in the m i n i m u m separat ion distances specified in Table 2-6 of NFPA 30 but the present separat ion distances appear to be too excessive.

Exception No. 2 has been modif ied to allow a fur ther reduct ion in the m i n i m u m separation distances where the fueling operat ion occurs in a controlled env i ronmen t which is generally no t accessible to the public. In those cases the hazard represented is m u c h less severe than at a public service station. Thus, it would be reasonable to allow for furdaer reduct ions in the required separat ion distances especially where the tanks are protected aboveground tanks or are installed in vaults.

It should also be no ted that the Separation distances presently specified in Section 2-4.2.2 are entirely arbitrary and were based on the assumpt ion that unpro tec ted aboveground storage tanks could be allowed. An arbitrary reduct ion factor of 50 percent was allowed for fire resistant tanks or tanks installed in vaults. This proposal provides some rationale related to the separat ion distances required in NFPA 30. It also recognizes the special passive fire resistive protection provided to aboveground storage tanks which are either installed in vaults or are protected aboveground tanks. COMMITI 'EE ACTION: Reject. COMMITTEE STATEMENT: It was the Technical Commit tee ' s specific intent to allow the option of a traditional aboveground storage tank for these systems. Also, the separat ion distances imposed by 2-4.2.2 were deliberately chosen to limit the option of aboveground tanks to relatively large sites. To adopt this proposal would negate dlis philosophy.

SUBSTANTIATION: At many fleet fueling facilities, 50 ft separa- tion distance is no t available between fuel d ispenser and tank. Fire exposure is less with Class II and IlIA liquids and dispensing directly f rom the tank should be allowed without 2 hour fire resistive tanks. COMMITI 'EE ACTION: Reject.

SUI~TANTIATION: This proposal recognizes protected aboveground tanks as newly def ined in a compan ion proposal with ,~lPropriate installation requ i rements in a new Section 2-4.6. It

ows such tanks to be installed at reduced separat ion distances which are comparable to those allowed by NFPA 30 for aboveground storage tanks at locations other than automotive service stations. A reduced separat ion distance of 15 ft for dispensers related to these tanks is also proposed which is less than the 25 ft separat ion distance allowed for fire resistant tanks. Due to the addit ional protect ion provided by protected aboveground tanks, this reduced separat ion distance appears reasonable. COMMITTEE ACTION: Reject.

2-4.5 Fire Resistant Tanks. Fire resistant tanks shall comply with the following:

(a) The construct ion tha t provides the required fire resistive protect ion shall prevent release of liquid, failure of the primary tank, failure of the suppor t ing structure, and i mpa i rmen t of vent ing for a period of no t less than 2 h r when tested using the fire exposure env i ronmen t described in UL 2085, Out l ine of Investigation for Insulated Aboveground Tanks for Flammable and Combust ible Liquids, or equivalent test procedure , unless the tank is nrotected with a device that neutralizes the ootentlal for auto-iuinition in which case t empera tu re rise s h a l l ~ o t apply, v SUBSTANTIATION: U-FUEL IGNITION SUPPRESSION SYSTEM (PATENT PENDING)

1. U-Fuel cont inues to strive to build the "World's Best" Aboveground Fuel Systems and is known for its innovative features that increase the safety, reliability, a n d envi ronmenta l fr iendliness of fuel systems. The U-Fuel Internal Ignition Suppress ion System (IS2) is a result of an effort to logically study the factors necessary for ignition in an a b o v e g r o u n d storage tank engulfed in fire, and de te rmine the most effective way to negate the potential for combust ion.

2. Many fire jur isdict ions are conce rned about the potential for ignition in an aboveground tank and are requir ing tanks be insulated to prevent the steel of any empty tank f rom reaching an

average tempera ture of 260 ° above amb ien t and the ignition tempera ture of hep tane at 400°F f rom being exceeded in a two hour period. The problem with this approach is that it disregards the ASTME D4814-92c composit ion of gasoline, the ignition require- ments of gasoline and similar fuels, and the dynamics involved in the hea t ing of gasoline in an aboveground tank involved in a fire.

GASOLINE IS A MIXTURE OF LIQUID HYDROCARBON WITH MULTIPLE BOILING POINTS.I ,2

A. ASTM D4814-92c sets forth the distillation specifications for ghasoline and provides for five volatility classes rang ing f rom "A" for

ot weather to "E" for cold weather. The "E" class is the mos t volatile, with a m a x i m u m of 10 percent of the gasoline being distilled at 122°F. Class "A" is least volatile, having a m a x i m u m of 10 percent distillation at 158°F. The m a x i m u m end point for all volatility classes is 437°F. 1

B. For gasoline vapors to ignite there mus t be a supply of oxygen, in most cases air.3 "l'his airYvapor mixture mus t be propor t ioned accurately within the limits of f lammabili ty or ignition, even if a t t empted deliberately byspark, will not occur?t, 5 The gasoline vapor mus t be in the range of 1.4 to 7.4 percen t of the air for the mixture to be f lammable.6 Below 1.4 percen t the mixture is too lean and will not ignite. Above 7.4 percent the mixture is too rich.7 Those who have tried to start an engine which is "flooded" have exper ienced a gasol ine /a i r mixture above 7.4 percent , too rich to ignite.

C. Aboveground tanks are now required to have vents that are normally closed except when vent ing u n d e r a pressure or vacuum condit ion.8 This restricts the free flow of air into the tank. This restriction of air flow with the h igher molecular weight and density of gasoline vanors creates an env i ronmen t in the tank that is difficult to ignite.6,7,9 '

D. If an aboveground tank is involved in a fire, regardless of design, whether a single wall steel tank, double walled, UL-2085, UFC79-7, or SwRI 93-01, the gasoline inside will absorb the h e a l

Jus t as when water can only be hea ted to its boil ing point of 212°F until it is all boiled off, the same th ing occurs with each hydrocarbon tha t makes up gasoline. As the tempera ture of gasoline increases to the boiling poin t of the first liquid fraction, the gasoline tempera- ture stabilizes at that boiling point, say 122°F, until that fraction is boiled off. T h e n the t empera tu re of the gasoline increases to the boiling poin t of the next fraction where it stabilizes until tha t fraction is boiled off.10,11 As long as heat is appl ied to the tank this process cont inues to repeat itseff until all the fractions are boiled off and there is no gasoline left in the tank at a m a x i m u m of 437°F.10,1 While this process is happen ing the vapors of the different fractions are being vented and burn like a large "Bic" lighter. Tim gasoline vapors within the tank become more and more concent ra ted and above the flammability limit, far ther away f rom the ability to ignite.4,12

E. In an a t t empt to create a scenario in which ignition could occur in an aboveground tank due to rapid hea t rise, the possibility of induct ing air into a tank after a fire, du r ing the cooling phase, was studied. Using Charles Law on the proport ional expansion of gases with temperature ,13 the percentage of air that could en ter a tank when cooled was calculated:

Beginning Ending Percent air en te r ing Percent Temp T e m p (After cool down) Difference 800 70 58 42

1,000 70 64 36 2,000 70 79 21

The worst possible condition, hea t ing a tank to 2,00O°F and cooling it down to 70 ° would allow for 79 percen t of air to enter the tank on cool down. The resul t ing difference is nearly three t imes greater than the uppe r f lammabili ty limit.

3. The U-Fuel Ignition Suppress ion System was developed to fur ther limit the potential for ignition. It works by injecting an inert material into the tank which due to its chemical, dilution, and diffusion properties, limits possible ignition of gasoline vapors. This process also decreases the hea t inside the tank.

4. The inert material used by U-Fuel is a combina t ion of water and biode~ra.dable propylene glycol, a d d e d for freeze protection. Water is used since it expands 1,673 t imes its volume when it forms steam.14 It only takes 7.2 gal of water to generate en o u g h s team to fill a 12,000 gal tank. And when water becomes s team it absorbs a large a m o u n t of heat, 970.4 Btu/ lb. 15

5. In actual tests of the U-Fuel T h e r m o Tank with Ignition Suppression System, s team was rapidly genera ted a n d d i s p e r s e d t h roughou t the tank, causing a significant d rop in all thermal couple sensors moni to r ing the internal tank temperature .16

6. Anyone who has exper ienced eng ine problems due to wet fuel can attest to the ignition suppress ion capability of water and water vapor. With the U-Fuel Ignition Suppression System s team displaces tile gases in the tank and limits possible ignition. Steam is widely

(Log #34) 30A- 26 - (2-4.5): Reject SUBMITTER: Rick Thornberry , ConVault RECOMMENDATION: Delete present Section 2-4.5 and substitute a new Section 2-4.5 as wording the following:

2-4.5 Protected Aboveground Tanks. Protected aboveground tanks shall comply with the following:

(a) Each protected aboveground tank shall be labeled to show compliance with SwRI 93-01, Test ing Requi rements for Protected Aboveground Flammable Liquid/Fuel Storage, UL2085, Standard for Insulated Aboveground Tanks for Flammable and Combust ible Liquids; or an approved equivalent test procedure.

(b) The re shall be no openings in the aboveground storage tank except those necessary for access to, inspe~ection of, filling, emptyin g and vent ing of the tank. All openings shall be located in the top of ' the tank.

(c) In locations subject to uplif t ing by g r o u n d water or flooding, each protected aboveground tank shall be anchored to resist the uplift forces.

(d) Each protected aboveground tank shall be resistant to damage f rom impact of a motor vehicle as de t e rmined in accordance with SwRl 93-01 or UL 2085 or shall be protected by collision barriers des igned to resist the impact force specified in SwRI 93-01 or UL 2085.

(e) Vent pipes provided for normal tank vent ing shall te rminate at least 12 ft (3.6 m) abow~ g r o u n d level.

(f) Paragraph 2-3.5.7 of NFPA 30, Flammable and Combustible Liquids Code, shall no t be used to reduce the size of the emergency vent provided for the aboveground storage tank.

(g) Each protected aboveground tank shall be provided with enclosed secondary con ta inmen t having emergency vent ing installed in accordance with NFPA 30, F lammable and Combust ible Liquids Code.

(h) Where projectile protect ion is requi red by the authori ty having jurisdict ion, each protected aboveground tank shall be bullet resistant as de t e rmined in accordance with SwRI 93-01 or UL 2085. SUBSTANTIATION: A new section for protected aboveground tanks which have been tested and evaluated in accordance with SwRI 93-01, Test ing Requi rements for Protected Aboveground Flammable Liquid/Fuel Storage Tanks, or the p roposed new UL 2085, Standard for Insulated Aboveground Tanks for F lammable and Combustible

Liquids, is p roposed to recognize such tanks whicb provide greater protect ion to the primary tank and its contents than fire resistant tanks presently regulated by Section 2-4.5. In particular, protected aboveground tanks have a h igher level of fire resistive protect ion based on the tempera ture rise criteria conta ined in SwRI 93~1 and UL 2085 as compared to UL Subject 2085 for fire resistant tanks. Both SwRI 93-01 and UL 2085 limit the tempera ture rise of the primary tank to 260°F above ambien t and the m a x i m u m thermo- couple on the surface of the primary tank to 400°F as compared to UL Subject 2085 which limits the average t empera tu re rise of the steel tank to 800°F above ambien t with a m a x i m u m tempera ture rise of any the rmocoup le l imited to 1,000°F above ambient . A hose s tream test is also requi red after the fire test by SwRI 92-01 and UL 2085 for protected aboveground tanks but is no t inc luded in UL Subject 2085 for fire resistant tanks. SwRI 93-01 and UL 2085 also have per formance criteria for vehicle impact resistance and bullet impact resistance for protected aboveground tanks.

The proposed requi rements for protected aboveground tanks are very similar to those conta ined in Appendix II-F of the 1994 Uni form Fire Code and also parallel those in Section 2-4.5 of NFPA 30A for fire resistant tanks. An option is provided for the authori ty having jurisdict ion to require bullet impact resistance in those jurisdict ions where there is a concern about such tanks being subject to projectile impacts such as drive-by shootings, stray hun te r s ' bullets, or o ther acts of vandalism. COMMITI'EE ACTION: Reject. COMMITI'EE STATEMENT: This would create a new category of aboveground tank tha t is actually a subset of "Fire Resistant Tanks," as def ined in NFPA 30A, and are thus already allowed. The proposal fur ther incorporates terminology tha t is no t recognized by NFPA 30A, but is directly related to another , different code. This will only lead to confusion.

(Log #35) 30A- 27 - (2-4.5(a)): Accept in Principle SUBMITTER: Rick Thornberry , ConVault RECOMMENDATION: Delete the wording presently conta ined in Section 2-4.5(a) and substi tute the following:

2-4.5(a) Each fire resistant tank shall be labeled to indicate that the tanks has been evaluated in accordance with SwRI 93-01 or an approved equivalent test s tandard. SUBSTANTIATION: Since there is now available a full test s tandard des ignated as Southwest Research Institute Test Procedure 93-01, Test ing Requi rements for Protected Aboveground Flammable Liquid/Fuel Storage Tanks, there is no longer a need to describe the per formance aspects of a test protocol which references a UL Subject Out l ine of Investigation.

This proposal will no t el iminate the use of UL Subject 2085 where the authori ty having jurisdict ion approves it as an equivalent test s tandard. At this t ime tile UL Subject 2085 Outl ine of Investigation for Insulated Aboveground Tanks for Flammable and Combust ible Liquids is a moving target since it is unde r revision and has not yet been finalized as a full UL standard. With such a state of flux, it would be preferable to reference a full test s tandard such as SwR193- 01 so that the authori ty having jurisdict ion can rely on a label to assure h im that the fire resistant tank has been properly tested and evaluated to mee t the in t ended per formance of this section of NFPA 30A. COMMITI'EE ACTION: Accept in Principle.

Revise 2-4.5 as follows: 2-4.5* Fire Resistant Tanks. Fire resistant tanks shall be listed for

the use in tended and shall comply with all of the following: [ Rest of 2-4.5 to remain the sam e. ] Add an Appendix to 2-4.5 to read: A-2-4.5 NFPA 30A requires a "fire resistant tank" to survive a two-

hou r fire test us ing the fire exposure env i ronmen t described in UL 2085, Standard for Insulated Aboveground Tanks for Flammable and Combust ible Liquids, or an equivalent fire test protocol. It should be no ted that o ther similar fire test procedures are used, such as the Uni form Fire Code 's Appendix II-F, (title), and Southwest Research Insti tute 's 93-01, Test ing Requi rements for Protected Aboveground Flammable Liquid Fuel Storage Tanks, both of which use the same fire exposure. It should also be noted that the Uni form Fire Code uses the te rm "protected tank" to describe tanks that mee t Appendix II-F or SWRI 93-01.

Because of these differences, tanks will commonly be listed to both sets of criteria. Where this is no t the case, a tank labeled as "protected", in accordance with Appendix II-F or SWRI 93-01, can be considered to mee t the requi rements of 2~.5(a) . However, the opposite migh t no t be the case. In o ther words, a "fire resistant tank", as def ined in 2-4.5 (a), migh t no t mee t all the criteria for a "protected tank", as def ined by the Uni form Fire Code."

SUBSTANTIATION: This proposal adds a reference to SwRI 93491, a test s tandard fo rp ro tec t ed aboveground tanks, which is equivalent to UL Subject 2085present ly re fe renced in dais section. A copy of this test p rocedure has been forwarded to NFPA along with this code change proposal and is available for anyone who requests it.

This SwRI s tandard was developed to mee t the requi rements of the 1994 1 ~niform Fire Code, Appendix II-F and UFC Appendix Standard II-F-I for protected aboveground tanks. Tanks tested and evaluated in accordance with this s tandard will mee t or exceed the per formance criteria out l ined in UL Subject 2085. Thus , it should be an acceptable test m e t h o d for reference in this section. COMMITrEE ACTION: Reject. COMMITI'EE STATEMENT: It is no t possible to mee t this requi remen~ ff subjected to a serious fire, the fuel in the tank will be heated, will vaporize (at least gradually, over t ime), and the vapors will ignite as they are discharged f rom tbe vent.

COMMITrEE ACTION: Reject. COMMITI'EE STATEMENT: A Formal Interpretat ion has been issued on this paragraph that confirms that it was the Technical Commit tee ' s in tent tha t the interstitial space be provided with emergency venting.

(Log #23) 30A- 32- (2-4.5(g) (New)): Reject SUBMITTER: Rick Thornberry , ConVault RECOMMENDATION: Add a new Section 2-4.5(g) to read as follows:

2-4.5(g) Tanks having a top fill with a direct connect ion for a fuel- delivery hose or nozzle shall be provided with a noncombust ib le spill conta iner at the fill connect ion, fixed to the tank, and equipped with a manua l drain valve that drains into the primary tank. The spill conta iner shall have a m i n i m u m capacity of 5 gal (18.9 L). SUBSTANTIATION: This proposal requires a spill conta iner to be

~ rovided for top fill tanks having a connect ion for a fuel delivery ose or nozzle. The purpose of the spill conta iner is to capture any

incidental spills that may occur dur ing the connect ion an d disconnect ion of the fuel delivery hose or nozzle or any leaks that may occur dur ing the fuel delivery process. This will prevent an accidental release of fuel onto the g r o u n d and provide additional fire safety at a very minimal cost.

This proposal also specifies tha t the spill conta iner have a manua l drain valve that connects to the primary tank so that the spilled liquid would not be redirected to an enclosed secondary contain- men t vessel provided for the primary tank when a double wall type tank system is provided. Again, this will provide and addit ional level of fire safety and prevent the unnecessary contaminat ion of the secondary con ta inmen t when provided. This r equ i r em en t is very similar to the provisions in Section 5.7 of Appendix II-F of the 1994 I Jniform Fire Code. COMMrlq'EE ACTION: Reject. COMMITTEE STATEMENT: This would appear to endorse a

~ ractice that the Technical Commit tee deems unsafe: d ra in ing the ose into a spill conta iner in the open. To the extent possible, the

SUBSTANTIATION: This proposal is in tended to clarify the application of this section to the sizing of the emergency vent. As originally in tended, the purpose of this section was not to permi t a reduct ion in the size of the required emergency vent for a fire resistant tank in order to provided an added safety factor for the passive fire protection achieved with the fire resistive insulation encasing the primary tank.

N F P A 3 0 A ~ A 9 6 R O P

SUBSTANTIATION: This proposal reduces the percent limits of capacity at which the alarm is t r iggered and the fuel is shu t off or the flow restricted dur ing the filling process for aboveground storage tanks. The p roposed lower limits are consistent with the 1993 BOCA National Fire Prevent ion Code, the 1994 IFCI Uni form Fire Code, Appendix II-F, and the 1994 SBCCI Standard Fire Prevention Code. These lower limits provide a reasonable factor of safety for prevent- ing overfilling of aboveground tanks. The present limit of 98 percent for automatically shut t ing off the fuel flow into the tank

lows for no safety factor especially in areas with very warm days such as in the southwest part of the U.S. It is quite conceivable tha t a tank filled to 98 percent capacity in the early m o r n i n g in Phoenix could have a spill at the end of a ho t s u m m e r day due to the expansion of the liquid in the tank. The 98 percent capacity limit is

~ resently allowed for u n d e r g r o u n d storage tanks which appears to e reasonable for those installations since the tempera ture of the

liquid in the tank does no t vary significantly. The proposed addit ional factor of safety is well worth the slight sacrifice in holding

a~acity of these aboveground tanks. MMITTEE ACTION: Reject.

COMMITI'EE STATEMENT: The Technical Commit tee feels that its action on Proposal 30A-33 (Log #15) provides an adequate degree of safety.

(Log #14) BOA- 35 - (2-4.7.1): Reject SUBMITTER: Bruce L. Watts, Nantucke t Fire Dept., MA RECOMMENDATION: Insert the following sentence:

"Separation distance of chain link protective fencing located at commercial , industrial, governmenta l , manufac tu r ing establish- ments , construct ion sites, or o ther business sites, no t open to the general public, and in tended for fuel ing motor vehicles or mar ine craft, used in connect ion with their business, may be reduced to less than 10 ft (3 m) with the approval of the head of the fire depart- ment ." SUBSTANTIATION: In my capacity as Chief of this depa r t men t for 15 years, and dur ing my 17 previous years working as a call firefighter, I fully unde r s t a nd the impor tance of public safety in areas such as those in quest ion. However, my under s t and ing also extends to the safety of firefighters who, with the requi rements of security fencing, will be asked to enter a cage in order to f ight af i re . One can only speculate as to the hor ror and tragedy which may result dur ing such a fire which gets out of control, t rapping public servants within a caged area, leaving t hem defenseless and unable to escape.

It is my sincere belief that by giving the local fire chiefs the authori ty to to use their own s o u n d j u d g m e n t in de te rmin ing adequate fencing distance requirements , the needs for both public safety and the of the firefighters will be addressed, especially knowing that these areas are restricted from the general public. COMMI'I'TEE ACTION: Reject. COMMITrEE STATEMF3~IT: T he required separat ion between the tank and the fence increases safety by main ta in ing some distance between the tanks and vehicles. The authori ty having jurisdict ion can reduce the separat ion u n d e r the equivalency concept.

(Log #39) 30A-37- (2-4.7.1 Exception No. 2 (New)): Reject SUBMI'Iq'ER: Rick Thornberry , ConVault RECOMMENDATION: Add a new Exception to Section 2-4.7.1 as follows:

2-4.7.1 Tanks that are no t enclosed in vaults shall be enclosed with a chain link fence at least 6 ft (2 m) high. The fence shall be separated f rom the tanks by at least 10 ft (3 m) and shall have a gate that is properly secured against unau thor ized entry. Aboveground tanks shall be protected against vehicular collision by suitable barriers.

Exception ~[_Q~_: Tanks are not required to be enclosed within a fence if the property on which the tanks are located ~ has a per imeter security fence.

in tended function. SUBSTANTIATION: Presently tanks in vaults are no t required to be enclosed within a fence. This proposal allows fire resistant tanks to also be exempt f rom the fence enclosure unde r certain condi- tions. P ro t ec t edaboveground tarlks are very similar to tanks in vaults. The proposed exception for protected aboveground tanks allows those tanks located at facilities generally no t accessible to the public which are provided for fuel ing operat ions used in connect ion with their business to be located without a fence enclosure when the openings into the tank including the vents are secured against t amper ing without impair ing their function. The purpose of the fence is to prevent unau thor ized t amper ing with the tanks and their appur tenances . Protected aboveground tanks are des igned to be of substantial construct ion in order to provide the required fire resistive protection for the primary tank and resistance to vehicle impact. If the openings into the tank are properly secured to prevent tamper ing, then it appears reasonable to allow an exception for such tanks at locations tha t are generally no t accessible to the Pcublic.

"The delivery vehicle shall be separated f rom any aboveground tank by at least 25 ft (Class I liquid storage) or 10 ft (Class II or IliA liquids) ." SUBSTANTIATION: The fire exposure is m u c h less with Class II or IliA liquids. Many smaller aboveground tanks are filled by a pressurized delivery hose into the top of the tank. Twenty five foot hose would be required to fill tatlk which would increase potential of hose breakage and release of fuel. COMMITI'EE ACTION: Reject.

(Log #24) 30A- 39 - (2-4.9.2 Exception (New)): Accept in Principle SUBMITTER: Rick Thornberry , ConVanlt RECOMMENDATION: Add a new Exception to Section 2-4.9.2 as follows:

2-4.9.2 The delivery vehicle shall be separated f rom any aboveground tank by at least 25 ft (7.6 m).

Exception N o . l : No m i n i m u m separat ion distance shall be requi red for tanks tha t are filled by gravity.

Exception No. 2: The reouired m i n i m u m separat ion distance shall be ner'rnitted to be reduced to 10 ft (3 m~ where the fuel bein~ delivered is n o t a Class I liouid. SUBSTANTIATION: Thi sp roposa l allows a reduct ion in e required separat ion distance between the deliveryvehicle and an aboveground storage tank where the fuel being delivered is no t a Class I liquid. T h e p r o p o s e d dis tance reduct ion is f rom 25 ft to 10 ft. The in tent of the 25 f t separat ion distance was to provide for adequate dispersion of vapors du r ing the filling process so that they could not be ignited by the delivery vehicle engine and the engine

467

N F P A 3 0 A i A 9 6 R O P

air intake would not pick up the f lammable vapors which would cause the engine to race and overpressure the fill hose or cause other problems. However, with Class II liquids vapors shou ld not be a significant problem and the m i n i m u m separat ion dis tance could be significantly reduced while still providing a m i n i m u m 10 ft separat ion to prevent an inadver tent spill f rom becoming ignited and involving the delivery vehicle.

The 1994 IFCI Uni form Fire Code Appendix II-F allows the tank vehicle to be parked within any distance from a protected aboveground tank when the tank is being filled from the tank vehicle. Tlms, a 10 ft separat ion for the filling of tanks conta in ing Class II liquids appears to be a reasonable compromise and will still achieve an acceptable level of safety. COMMITTEE ACTION: Accept in Principle.

(Log #8) 30A- 43 - (4-2.3): Reject SUBMITTER: Gerald Holton, WI Dept of Industry, Labor & H u m a n Relations RECOMMENDATION: I propose dlat code section NFPA 30#- 4-2.3 be a m e n d e d to read:

"A control shall be provided tha t will permi t the dispensing device to be placed in operat ion only after the nozzle has been removed f rom it's normal nond i spens ing position. This control shall be manual ly ac tuated and shall no t be incorporated into the action of removing tile nozzle f rom its bracket. A control shall also be provided that will allow the dispenser to be s topped prior to die nozzle be ing placed in it's normal nond i spens ing position. This control shall be manual ly ac tuated and shall no t be incorporated into the action of placing the nozzle in its normal nondispens ing position. These controls shall be clearly identified and easily accessible at each fueling position." SUBSTANTIATION: The State of Wisconsin interprets this paragraph (as currently publ ished) , to require a dispenser to have two positive actions pe r fo rmed by the customer. On e action would place the d ispenser in operation (allow product flow) and the second would stop dispenser operation. These actions mus t be taken in addit ion to the removal or r ep lacement of the nozzle f rom its holder.

Please note that the term "dispenser" refers to all devices that dispense fuel. There are two types of dispensers. A self conta ined dispenser is a uni t with a suction p u m p in the above grade cabinet. This configurat ion pulls product f rom the tank. Tile more c o m m o n type of d ispenser is die "remote dispenser". This device is suppl ied

~ roduct f rom die tank by a submerged p u m p located in the tank el ow produc t level. All dispensers of a given product are suppl ied

by one "pump". The section of the code referenced has not changed since 1987.

The dispensers in use at that t ime normally required the removal of the nozzle f rom its bolder before a control handle could be moved to actuate a switch within the dispenser to allow product to flow. The cus tomer would then fill the t a n k a n d then have to move the control

(deactivating the switch and s topping p roduc t flow) in order to replace tile nozzle.

A c o m m o n issue is the m e a n i n g of two key words, switch and control. Thei r relat ionship to the operat ion of a dispenser (dispens- ing device) is critical to this code section. A control or control handle is used to actuate a switch in the dispenser. The switch, t h rough various relays, allows or stops p roduc t flow th rough the dispenser. We acknowledge that when all controls for a given product are placed in die off posit ion that the subm erg ed p u m p supplying product would he stopped. In die case of a serf conta ined dispenser die suct ion p u m p would stop when all controls for that p u m p uni t where placed in the off position.

The definit ions of switch and control are no t given in NFPA 30A. We have instead referenced Webster ' s Unabr idged Dictionary. The definit ions given do no t directly apply to the devices in question.

At issue here is the installation of electronic dispensers that require a cus tomer to remove file nozzle then push a but ton (dais would equal the dispenser control handle) to actuate the dispenser switch. Upon complet ion of d ispensing file only action that can deactivate the switch is to re turn the nozzle to it's holder. This m e t h o d of tu rn ing a dispenser off is clearly a single action.

A hose failure or drive off could cause the nozzle to be removed f rom the hose, in such a case, there would be no mean s of s topping the dispenser at the island as the re would be no nozzle. Ano the r problem could occur i f a nozzle locked open. In this instance a person would have to force a nozzle tha t is d ispensing product up into the cabinet. The purchas ing public has no idea as to how the single action configurat ion of d ispenser operates and would no t readily know how to stop the dispenser. The dispenser configurat ion tha t the public is most familiar with has a of control o ther than the nozzle that can be manual ly actuated to tu rn off the dispenser.

The a r g u m e n t that has been presented to me is that the station emergency shutof f meets the in tent of this section. This shutoff clearly is no t available to the customer. Tile normal location of this shu tof f i s the control console inside the station. A cus tomer would have a hard t ime get t ing file a t tent ion of the station a t t endan t at most self serve stations. The cus tomer would t hen have to convince the a t t endan t to shu t down all the dispensers in operat ion as that is tile funct ion of the emergency control. My exper ience is that often it is difficult to see the a t t endan t m u c h less get their a t tent ion and have the d ispenser shu t off.

The commenta ry provided in the handbook makes direct reference to a single act ion dispensing nozzle failing to provide a positive p u m p shutoff. The Commit tee apparent ly rejected one proposal to allow single action dispensing for the reasons stated in the co m m en - tary. The dispenser configurat ions in ques t ion appear to mee t the in tent of the code at the point of start ing the d ispensing process. These same dispensers, however, fall into the category of single action at the complet ion of die d ispensing operation.

The State of Wisconsin recognizes that allowing nozzle p lacement in the holder as a m e t h o d of control is user friendly and a conve- nience to the customer. Dispensing devices will be allowed that have this feature, provided tha t a clearly marked stop control but ton is installed or retro-fit at each fueling station or on each side of a

468

N F P A 3 0 A - - A 9 6 R O P

multiple p roduc t dispenser. This bu t ton would be considered as the control to provide positiw." dispenser shu t down. This stop control button, a l though no t mee t ing the letter of the code language as it currently exists, would seem to mee t the intent.

Our goal is to make a positive means of dispenser shu t off immediate ly available to the customer• We do not in tend to require that the same control but ton be redes igned to per form both the start and stop funct ion as dais would probably require a major wiring change. Manufacturers of dispensers, of the single action configura- tion, have indicated tha t the control bu t ton and labeling are available for new units, and as a retrofit package.

NOTE: Suppor t ing material is available for review at NFPA Headquarters . COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The text p roposed by the submit ter does no t clearly address the concerns discussed in the substantiation. Thus, the Technical Commit tee is no t certain what problem is being addressed. The Technical Commit tee points out that it is the deliberate in tent of subsect ion 4-2.3 that emergency controls be located a safe distance away f rom the d ispensing devices and remote pumps .

A stabilizer bar is used to position the valves in tire relatively large opening under the dispenser. The valve itself and not the flexible connector or product piping should be moun ted to the stabilizer bar.

7-1 Scope. This Chapter shall apply to the installation of electrical wiring and electrical utilization equipment in areas here liquids are stored, handled, or dispensed.

7-2 General Requirements. 7-2.1 All electrical wiring and electrical utilization equipment shall

be of a type specified by and shall be installed in accordance with NFPA 70, National Electrical Code.

7-2.2 All electrical wiring and electrical utilization equipment shall be suitable for the locations in which they are installed.

7-3 Installation in Hazardous (Classified) Locations. 7-3.1 Table 7-3 shall be used to delineate and classify areas for the

purpose of installation of electrical wiring and electrical utilization equipment. The designation of classes and divisions of hazardous (classified) locations is def ined in Chapter 5, Article 500, of NFPA 70, National Electrical Code.

7-3:1.1 In designated a classified area, a classified area shall not extend beyond a solid floor, wall, roof, or other partition that has no communicating openings.

7-3.2 The area classifications given in Table 7-3 shall be based on the premise that the im~dlation meets the applicable requirements of this code in all respects. Should this not be the case, the authority havingjurisdictinn shall be permitted to determine the extefit of the classified area.

7-3.3 All electrical wiring and electrical utilization equipment that is integral with the dispensing hose or nozzle shall be suitable for use | in Class I, Division 1 hazardous (classified) locations.

CLog #7) 30A- 58 - (Table 7): Accept in Principle S U B ~ Detlev E. Hasselmann, Hasstech, Inc. RECOMMENDATION: Delete the reference to Vacuum-Assist Blowers from Table 7.

"This action will not c h ~ g e the safety requirements for vacuum assist blowers since they are covered under paragraph 4-5.1, which requires them to be individually listed for use in a specified manner." SUBSTANTIATION: Thejusfiflcation for this change is that there is presently a dual standard. Anumber of dispenser manufacturers have obtained UL listing for their vacuum assmt blowers located in the canopy of dispensers. This location is in a non.classified area according to UL Standard 87 because it is above 4 ft from grade. An inspection of the UL listed dispensers with vacuum assist blowers in the canopy will show that nonexplosion proof components such as switches and neon lights are located next to the blowers.

If the same blower was located outside of the dispenser, it would create a Division 2 area for 18 in. all around the blower and up to 18 in. above grade level within 10 ft around the blower because of Table 7. Thus the exclusion of a sizable area provided by the dispenser section of Table 7 (which places the area dassificatinn within dispensers under UL 87) is not available to a vacuum assist blower that is external to a dispenser. A vacuum assist blower should have the same area classification

whether it is inside a dispenser or not. If the committee wants to retain the Table 7 requirement~ for area classification of vacuum assist blowers, then it should also insist that UL 87 comply with the same requirements. If UL 87 does not want to change, then the NFPA 30A committee should remove the reference to that standard in Table 7.

I am requesting this as an emergency action item because this dual standard'is having a significant financial impact upon our company. Some dispenser manufacturers are making the claim that their vacuum assist blowers do not require a classified area around the blowers while pointing out that our vacuum assist blowers require an extensive classified area, even though they are of sinailar design. Potential customers are impressed by these claims and purchase equipment based upon them. This is unfair competition allowed by a dual standard. We are also encountering inspectors who are requiring explosion-

proof electrical fittings within a 10 ft radius for roof mounted installations of our sealed blowers because of Table 7. This is ridiculous in view of the fact that if we took our blower from the well ventilated canopy or roof location and located it inside an enclosed dispenser next to neon lights, there is no requirement for the neon ligfits to be explosion-proof. The inspectors state that since the dispensers are UL listed, they have no concern after the electrical wiring enters the dispensers.

We have contacted several listing agendes, and they have all stated they are bound by NTPA 30A to require Our sealed blowers to coml?lywith the Table 7 requirements for the dassitied areas. This in spite of the fact that we have used our blower design for 17 years without problems or leaks. The listing agencies and the local inspectors have indicated they would reconsider their position if Table 7 would allow them to do so. We, therefore, request your careful consideration of our proposal. COMMITrEEACTION: Accept in Prindple. Add an exception to Section 7-3 to read: "The extent of the classified area around a vacuum-assist blower

shall be permitted to be reduced if the blower is specifically listed for such reduced distances." C o M M r r r ] ~ b ~ r A ~ : The Technical Committee does not agree that this information presented by the submitter jnstlfies deleting the area classification requirements for all such listed equipment, only those whose listings indicate that the area classifica- tion can be safely reduced.

10. Only approved containers may be filled from these tanks and dispensers. No vehicles may be fueled by these units.

11. All other applicable provisions of Chapter 9 shall apply. SUBSTANTIATION: To allow dispensing of combustible liquids from above ground integral storage tanks at public service stations into approved containers without having to met NFPA 30A TIA 90-1 distance rules.

It has come to our attention that the code does not recognize above ground tanks at public service stations that dispense fuel oil or kerosene to approved containers for the purpose of home heating unit fuels.

We must allow these type tanks for use by the public at service stations because: (a) kerosene is the sole form of home heating for many people in the United States; (b) the safety record is excellent; (c) Steel Tank Institute's F911-91, R912-91 and Petroleum Equip- ment Institute's RP200-92 and UL 142 all indicate safe engineering practices for dike tanks; (d) the public is not allowed to dispense from these tanks to motor vehicles due to price differences.

"9-3.5 The provisions of 2-1.1 shall no t prohibi t the dispensing of Class I and Class II liquids n the open from a fuel dispensing system supplied by an ~ aboveground tank, not to exceed 6000 gal..." SUBSTANTIATION: It has been documented that the majority of fires involving aboveground tanks have occurred during the refilling operation. Therefore, dae smaller tanks that have to be refilled more often are in my opinion a greater risk. Section 2-4 of the code adequately regulates spill control, tank location, piping and ancillary equipmenL If the fleet operator has limited space, the operator may use a fire resistive tank or vault to reduce spacing requirements.

Currently 9-3.5 is being misunders tood by some authorities having jurisdiction. Byadding the word "existing", all previously approved small aboveground tanks can remain in use.
