- Overfill Protection

Summary of Overfill Protection Device Analysis

January 26 , 200 9 1.0 Background This report summarizes the meth odologies and findings of three reviews of information relat ed to overfill protection devices. As part of the regulatory development process, EPA’s Office of Underground Storage Tanks ( OUST ) is gathering information on overfill protection devices (ball float valves, automatic shutoff devices, and overfill alarms), including use, cost, state regulations , and language contained in standard codes of practice
. Th is report includes summaries of the following three research tasks: 1. Equipment and installation costs for three overfill devices 2. Industry

standards on allowed use of and restrictions for the overfill protection devices 3. R egulatory

and policy

information on state requirements Four a ppendices are also included :  Appendix A : Detailed Equipment and In stallation Cost Data  Appendix B : In dustry Standards for Allowed Use and Restrictions on Use
 Appendix C : Im ages from Industry Standards
 Appendix D : State / Territorial Regulations and Policies In formation regarding the frequency of use will be provided in a separate summary document. 2.0 Equipment and Installation Cost Summary Methodology Using Internet sources and by contacting not more than nine vendors or installation contractors of overfill equipment 1 

### , the average equipment and installation costs of three overfill devices were estimated
. To the extent possible, c osts were intended to represent prices across the United States
. Overfill equipment vendors were located b y s earching online industry directories and conducting general Internet searches. Companies listed in the Petroleum Equipment Institute (PEI) member directory were re searched to confirm whether the vendors sold overfill equipment devices and if prices were available online . If manufacturer Web sites listed products but no t prices, additional online searches were conducted in order to

1 In order to comply with the Paperwork Reduction Act, no more than nine contract ors were contacted.

### 2

locate prices from other distributors. Additional device prices were obtained from www.petrodirect.com
. A list of i nstallation c ontractors w as comp iled from lists of companies o n vendor Web sites (e.g., Krueger Sentry Gauge’s list of preferred distributors) , lists of certified contractors on state underground storage tank (UST ) program Web sites, and results from general Internet searches. No contra ctor Web site s accessed i ncluded pricing information. N ine installation co ntractors (one from each EPA region) were contacted for pricing information. Each company ’ s Web site advertise s that they perform UST repairs, retrofits, and installations. Resu lts Interviewed contractors annually install more automatic shutoff valves on average (5 2) than ball float valves (33) or overfill alarms (15)
. Five of the nine contractors install automatic shutoff valves in approximately 100 percent of tanks. Four contractors reported installing ball float valves in all new tanks
. Interviewed c ontractors rarel y install overfill alarms. One contractor reported that all new tanks are installed with ball float valves, automatic shutoff valves, and overfill alarms. Convenience stores and commercial sites are the most frequent clients served by these contractors. See Table A4 for more details. P rices for 3 1 ball float valves were located online , while four of the contractors reported prices (see Table A1)
. These devic es were manufactured b y four different companies. The average cost of a ball float device was $ 8 1 (Table 1) . Prices ranged from $33 to $221. Average i nstallation costs for a new tank w ere estimated as $75 and retrofit installation costs estimated by contractors ranged from $2,000 to $10,000. Prices for 4 0 automatic shutoff valves were located online , while six of the contractors reported prices (see Table A1) . These devices were manufactured b y three different companies. The average cost of an autom atic shutoff valve was $5 67 (Table 1) . Prices ranged from $328 to $1, 400
. Average i nstallation costs for a new tank rang ed from $150 to $800 and one contractor estimated retrofit installation cost s as $5 0 0
. Prices for two overfill alarm units were loc ated online . These devices we re manufactured by two different companies and cost $41 5 and $434 (see Table A1)
. One contractor interviewed indicated they charge $700 for the device. Contractors reported that tank owners do not ty

picall y install independent overfill alarms, but rather install automatic tank gauge (ATG) s ys tems which include audible and visual overfill alarm components. The estimated average cost of installation reported for these ATG s ys tems was $3,433. Average i nstallation cost estimate s ranged from $1,000 to $10,000 , depending upon the number of tanks and the distance from the console
. Interviewed c ontractors did not perform retro fit installation of overfill alarms
.

### Ball float valves have the lowest average device cost ($ 81 ) and installation cost for a new tank ($ 75 ) , but high retrofit installation costs ($2,000 to $10,000)

. Automatic shutoff val ves cost more than ball float valves ($5 67 ), but have the lowest average retrofit installation cost s of the three devices ($ 500 ) and w ere reported b y contractors as the most common choice among tank owners with existing tanks
. Overfill alarms have the lar gest average total cost for new tanks ($ 1 , 516 to $10, 516 ). Although the nine contractors were selected to provide information applicable across the United States, the results do not provide information for all overfill equipment. Most contractors conta cted only install either ball floats or automatic shutoff valves, causing less information to be available for equipment and installation estimates for each overfill device (Table 2)
. For example, the average retrofit installation costs for ball floats is based on estimates from only three contractors and new tank installation costs are based on two contractors. Combined with online pricing, the equipment cost estimates for ball floats and automatic shutoff valves are the most representative data gathered

3.0 Industry Standards Methodology Three industry standards were researched for information about the allowed use of and restrictions for the three overfill protection devices . The industry standards included: 1. American Petroleum Institute (API) Recommended Practice (RP) 1615. 1996. “Installation of Un derground Petroleum Storage Sy stems.” American Petroleum Institute and Strategies for Today ’s Environmental Partnership (STEP): Washington, D.C. Fifth edition; 2. National Fire Prevention Association (NFPA) 30 . 2008. “Flammab le and Combustible Liquids Code
. ” National Fire Protection Ass ociation: Quincy, Massachusetts; and 3. P etroleum E quipment Institute (PEI) RP100
- 05. 2005. “Recommended Practices for Installation of Underground Liquid Storage Sy stems.” Petroleum Equipment Institute: Tulsa, O klahoma
. All s pecific instances where automatic shutoff valves, ball float valves, overfill alarms, and any of their aliases or synonym ous names (e.g. , “flapper valves,” “vent
- restrictive valves”) appeared in the industry standards were copied verbatim into Appendix B
. Additionally , non - specific, general discussions usage of “overfill prevention” or related issues , such as electrical wiring, fill pipe, and vent placement restrictions, were also copied directl y. Except for NFPA 30, the industry standards documents also included images throughout with specific mentions of overfill devices. These diagrams show e xample s of device installation locations in a variety of situations, such as in single tanks or in an array of tanks. These images are included in Appendix C
. Results The three standards varied considerabl y in their discussion of overfill prevention devices. The PEIRP contains the greatest information about the three specific devices , including device
- specific information and warnings. The APIRP includes inf ormation regarding general overfill prevention, but does not explicitly mention any

of the three devices. The third standard , NFPA 30, also does not mention specific device s , but does include relevant information about electrical wiring, a topic that pert ains to installation aspects of overfill alarms. Automatic Shutoff Valves Automatic shutoff valves are also referred to as “flow shut
- off devices” and “flapper valves.” Due to the design of the valve mechanism, automatic shutoff valves for use with USTs should only

be used with gravity

deliveries (PEI/RP 100
- 05). Furthermore, they should only

be used where there are liquid
- tight connections between the delivery hose and the fill pipe (PEI/RP 100
- 05). The PEI RP 100
- 05 includes three major warnings regarding the use of automatic shutoff valves:

### 5

1. The gauge riser, above the automatic shutoff valve itself, must be properl y s ealed or else product will pour from the gauge opening when the valve closes. 2. Automatic shutoff valves should not be installed on tanks equipped with remote
fill pipes and a gauge riser located directl y above the valve. 3. If automatic shutoff valves are installed on tanks equipped with remote
- fill pipes and a gauge riser directl y above the valve, it is necessary to have installed a “trap do or,” a speciall y- designed fitting that automatically closes the gauge opening in the riser during delivery . The RP states that if “a trap door or equivalent device is not installed in the gauge riser, a properl y tightened, threaded pipe cap must be instal led in the riser above the flow shut
- off device and a separate gauge riser installed to permit manual gauging of the tank.” Ball Float Valves Ball float valves , often referred to as “ float
- vent valves ” or “ vent - restriction devices, ” are installed inside the UST just below the vent opening. These valves must be installed in an extractable fitting to allow access for inspection, maintenance, and tightness testing (PEI/RP 100
- 05). During normal operation of a ball float valve the tank becomes pressurized an d can creat e a hazardous condition (PEI/RP 100
- 05). The general remedy , to release flammable vapors at grade , is not recommended by the PEI RP. The PEI RP also does not recommend installing or continuing to use ball float valves due to this potentially h azardous maintenance concern . The PEIRP lists a series of additional warnings regarding the us e of ball float valves (see below). Most warnings directly limit the installation of ball float valves due to the concerns regarding their safety . Ball float valves tend to produce additional pressure in an already pressurized, confined, and potentiall y explosive atmosphere. Installation Warnings for ball float valves (PEI/RP 100
- 05):
 “ Ball float valves must not be installed in storage sy stems where there is any possibility

of a pumped delivery

into the tank. When an overfill occurs in conjunction with a pumped delivery and a tight
- fill connection, the tank becomes severel y over - pressurized and may rupture as a result. ”  “ Ball float valves must not be installed in storage sy stems that are equipped with suc tion pumps and air eliminators.”
 “ Ball float valves will not work when coaxial Stage I vapor recovery is used unless special fittings are installed. ”  “ Ball float valves must not be used on tanks equipped w ith remote
- fill pipes and gauge openings. If the vent
- restriction device closes during a delivery when the gauge opening is uncapped, product will pour from the gauge opening onto the ground. ”  “ When installing flow shut
- off devices, do not install a ball
- float valve unless the ball
- float activates at a level higher in the tank than the flow shut
- off device. ”
 

### “ Ball float valves should not be installed on emergency
- generat or or heating
- oil supply tanks.”

### 6

Overfill Alarms 

### Also referred to as “external sign aling devices,” overfill alarms are required by many authorities having jurisdiction as a necessary device in overfill prevention
. They operate in conjunction with an automatic tank gauging s ys tem and annunciate when the product in the tank reaches a cert ain level. T o remain effective , the alarm must “provide visual and audible signals to the delivery person” and “be located in close proximity to where the delivery

personnel stand during delivery” (PEI/RP 100
- 05). Alarms are recommended by all three ind

ustry standards. The PEI RP recommends that an alarm be clearly

labeled as a “tank overfill alarm,” or with similar language, so that it is easily recognizable
. T he PEI RP also recommends that power to all alarms be uninterrupted. General Notes on Ove rfill Prevention Information contained in the three industry standards relevant to overfill protection devices includes general discussion related to installation and operation. During installation, installers must consult manufacturer instructions and “refer to the gauging chart provided b y the tank manufacturer to determine the correct distance below the tank top for that device” (PEI/RP 100
- 05). As stated in NFPA 30, “electrical utilization equipment and wiring shall not constitute a source of ignition for any i gnitable vapor that might be present under normal operation or because of a spill.” Furthermore, the PEI RP suggests that overfill device installation be regulated as a percentage of tank capacity , not a percentage o f tank diameter. Additionall y, when applicable, the thickness of double
walled tanks and the height of manway covers above the tank primary wall must be taken in consideration by

installers when determining the appropriate distance below the tank top to install an overfill device (PE I/RP 100
- 05)
. In order to operate successfully , any overfill prevention device must operate when a tank is nearl y full in order to alert the operator (PEI/RP 100
- 05). Both federal regulations and industry standards recognize the importan ce of having overfill prevention equipment that will:
 Automatically

shut off the flow of liquid into the tank when the tank is no more than 95 percent full;
 Alert the transfer operator when the tank is no more than 90 percent full b y restricting the flow of liquid into the tank or triggering the high
- level alarm; or
 Operate via other approved methods (NFPA 30). “Spills, drips, and overfills that occur during transfer operations from a delivery truck to the underground tank must be prevented or contained” (API/RP 1615). In order to contain small spills around the tank fills , spill
- containment manholes must be installed (API/RP 1615). Containment manholes can be containers with drain s that route any spilled product back into the underground tank. “The required size of c ontainment manholes varies according to state and local regulations” (API/RP 1615). Other methods of fluid removal, such as hand pumping, siphoning, and/or bailing are also available but are seen as not as practical as drains (API/RP 1615).

### 7

Industry st andards do not cite federal regulations, but suggest installation practices that mirror federal standards , especiall y 40 CFR §280.30
. For example, t o prevent overfills, the APIRP suggests that equipment be installed that will severel y restrict or shut of f the flow of product automatically or alert the operator in timely a fashion when an overflow is imminent. “Before the transfer, the tank must be checked to ensure that sufficient volume is available” (API/RP 1615). During the transfer itself, the operation should be “monitored continuously” (API/RP 1615). A final consideration during filling recommends that “tank venting s ys tems [...] be provided with sufficient capacity to prevent blowback of vapor or liquid at the fill opening while the tank is being f illed” (NFPA 30). The PEI RP recommend s that remote - fills should only be used “when necessary ; ” that any and all piping should be “slope[d] uniformly to the tank” to ensure proper drainage ; and that owners, operators, and installers use “caution when sele cting overfill protection devices for use with remote fills.” 4.0 Summary of State and Territorial Regulations and Policies Methodology By comparing state and territorial rules and policies to the federal regulations, state and territory requirements or policies were anal yz ed to determine to what degree states and territories matched federal standards and for language that matched or exceeded federal standards that specifically included the three overfill protection methods. State and territorial regulations and policies were accessed through EPA’s “State and Territory UST/LUST Program Status and Contacts ” W eb page 4



### . The “Technical Standards and Corrective Action Requirements for Owners and Operators of Underground Storage Tanks (UST),” contained with in Title 40, Chapter I , Parts 280.10
- 280.230 of the Code of Federal Regulations are the federal regulations encompassing all applicable USTs. 40 CFR Parts 280.20 and 280.30 directly regulate spill and overfill prevention equipment and control measures for all other regulated tanks . These regulations require states and territories to maintain the federal minimum protection and prevention measures for spills, overfills, discharges, and releases of petroleum products from USTs at the time of product delivery and filling. Results Results were tracked according to whether a state or territory incorporated the exact language or nearl y identical language to the federal regulations, as broken down into the smallest discrete sections. State and territory regul ations that exceeded federal standards were also tracked for comparison. Appendix D contains detailed results of and hy perlinks to the regulatory information , as well as the exact regulatory and policy language for states with regulations that are different from the federal version
. The major findings of the policy

analy sis are shown in Table 3

### M any states have incorporated the entirety of 40 CFR 280.20 and 40 CFR 280.30, the portions of Title 40 that directly discuss USTs and overfill prevention devices. Far fewer states or territories on average include sections 40 CFR 280.30(a) o r (b). For example, in regards to section 40 CFR 280.30(b), 30 states or territories make no specific reference to any technical and industry

standard, including those specifically mentioned in the federal regulations. Six states or territories have entirel y adopted or incorporated b y reference the federal standards: Georgia, Michigan, North Carolina, Northern Mariana Islands, Oregon, and Utah. Whereas these states have incorporated both Subparts B (280.20) and C (280.30), Kentucky onl y incorporates Sub part C (280.30). S even states ( Maine, Rhode Island, Delaware, Pennsylvania, Il linois, Texas, and Nebraska) specificall y bar the installation of ball float valves ( “ vent - float valves ” or “ vent - restriction devices ” ) in suction sy stems. Nebraska bans ball floats entirely after the effective date of regulation (September 2007). These seven states are the only states to specificall y ban the use of an overfill prevention device in regulatory language. Rhode I sland allows the use of “vent whistles” as an al arm s ys tem under the following circumstances:
 When tight
- fill, pump
- off deliveries are made;
 When the vent whistle is s et to alarm when the tank is 90 percent full;
 When the vent whistle is installed in a manner that allows for eas y annual inspection; and
 Where the vent opening is located within eight feet, or as close as practically possible, to the fill pipe. New Hampshire requires that “ all new underground storage tank s ys tems utilizing suction piping and an air eliminator be equipped with a high
- l evel visual and audible alarm ” or

### 9

“ a device that [...] automatically and completel y s hut[s] off flow into the tank .” New Hampshire requires either an overfill alarm or an automatic shutoff valve, but does not require installation of both. Current New Hampshire regulations do not ban the use of ball float valves . Therefore, it appears as though the use or installation of a ball float valve would also require the upgrade or installation of an overfill alarm or an automatic shutoff valve. Pennsylvania s pecifically bans the b ypassing of overfill protection. In this ban, Pennsylvania includes two examples of by pass: 1) coaxial vapor recovery sy stems by passing the flow vent valve , and 2) the use of a spill bucket drain valve. Additionally , the regulations state that where ball float valves are used on non
- suction s ystems, they must be fitted with extractors and must be readil y accessible for "removal and operational verification." Some states meet most of the federal regulations, but differ in only one or two sections. For example, in regards to 40 CFR 280.20 (c)(1)(ii)(C), Maryland requires only that the alarm annunciate within one minute before overfilling. Maryland does not include the alternatives given in this federal standard, to either “restrict flow 30 minutes prior to overfilling ” or to “ automatically shut off flow into the tank so that none of the fittings are exposed to product. ” However, th e fact that these two alternatives are not present in the Maryland regulations is the only signific ant difference between the Maryland and federal regulations. In contrast, the District of Columbia , which does not seem to include any federal regulations, has a regul ation that mimics 40 CFR 280.20 (c)(1)(ii)(C) . This regulation does not specify an al arm time for the overfill alarm, but does indicate that an alarm must be installed on pressurized sy stems
. Similarly to DC, Florida is a state that also meets few of the federal regulations. Florida meets federal criteria only for sections 280.20(c)(1)(i i)(A) and (B). However, in contrast to DC, Florida establishes its own performance criteria for regulation that do not seem to mimic federal standards. Inone instance, i n place of 280.20(c)(1)(ii)(C), Florida regulates that the "transfer operator [be al erted] with a high
- level alarm set at 400 gallons below tank top, but no less than one minute before overfilling."

PEI/RP100 - 05. 2005. “Recommended Practices for Installation of Underground Liquid Storage Systems.” Petroleum Equipment Institute: Tulsa, OK. 

## 1. INTRODUCTION [Page 1] 1.3 Scope. These recommended practices apply to underground, atmospheric, shop
- fabricated tanks, associated piping, and equipment intended to dispense gasoline, diesel, and related petroleum products into motor vehicles at retail, commercial, and government vehicle
- fueling facilities. This document does not address practices associated with the installation of storage systems for liquefied petroleum gases, liquefied natural gases, or compressed natural gases. The practices recommended in this publication are limited to installation procedures. [...] 

## 7. SPILL CONTAINMENT AND OVERFILL PROTECTION [Page 14] 7.3 Overfill prevention. Three types of overfill
-prevention devices are commonly used: alarms, flow shut
- off devices, and vent
-restriction devices. Overfill
-prevention devices should operate when the tank is nearly full. Consult the authority having jurisdiction to determine the level at which the overfill device should operate. Consult with the storage system owner to determine the delivery procedures that will be used to fill the tank. Select and install an overfill device that will be compatible with the anticipated delivery procedures. 7.3.1 Alarms. Alarms consist of an external signaling device that is typically connected to an automatic tank
- gauging system. To be effective, the alarm should:  provide visual and audible signals to the delivery person  be located in close proximity to where the delivery person stands during the delivery  be clearly labeled as a “tank overfill alarm” so that delivery personnel will recognize t

he device as an overfill alarm 7.3.2 Flow shut- off Devices. Flow shut
- off devices, often called “flapper valves,” are installed in the fill pipe of underground tanks and automatically stop the flow of product into the tank during a 

## [Page 15] delivery. After the main valve closes, various bypass mechanisms allow the contents of the delivery hose to be drained into the tank. In order to operate properly, shut
- off devices should be installed according to the manufacturer’s instructions, particularly with regard to attaching the shut
- off device to the drop tube and attaching the drop tube to the fill pipe. Shut
- off devices that are designed for use with underground tanks should only be used with gravity deliveries and where there are liquid
- tight connecti ons between the delivery hose and the fill pipe.

### B
- 3 In a remote
- fill installation, the gauge riser above the flow shut
- off device must be properly sealed or else product will pour from the gauge opening when the shut
- off device closes. WARNING: Do not ins tall flow shut- off devices on tanks equipped with remote - fill pipes and a gauge riser directly above the flow shut- off device unless a specially designed fitting (e.g., a “trap door”) that will automatically close the gauge opening is installed in the gaug e riser. If a trap door or equivalent device is not installed in the gauge riser, a properly tightened, threaded pipe cap must be installed in the riser above the flow shut - off device and a separate gauge riser installed to permit manual gauging of the ta nk. 7.3.3 Vent- restriction Devices. Vent
-restriction devices, often referred to as “float
-vent valves” or “ball
- float valves,” are installed inside the underground tank just below the vent opening. If, after considering all of the warnings listed below, a ball
- float valve is installed, it must be installed in an extractable fitting to allow access for inspection, maintenance, and tightness testing. When a ball float valve operates as designed, the tank becomes pressurized, creating a hazardous conditio n. The pressure is most often relieved by releasing flammable vapors at grade. For this reason, ball
- float valves are not recommended. WARNING: Vent - restriction devices must not be installed in storage systems where there is any possibility of a pumped delivery into the tank. When an overfill occurs in conjunction with a pumped delivery and a tight- fill connection, the tank becomes severely over- pressurized and may rupture as a result. WARNING: Vent - restriction devices must not be installed in storage systems that are equipped with suction pumps and air eliminators. WARNING: Vent - restriction devices will not work when coaxial Stage I vapor recovery is used unless special fittings are installed. WARNING: Vent - restriction devices must not be used on tanks equipped with remote - fill pipes and gauge openings. If the vent - restriction device closes during a delivery when the gauge opening is uncapped, product will pour from the gauge opening onto the ground. WARNING: When installing flow shut - off device s, do not install a ball- float valve unless the ball - float activates at a level higher in the tank than the flow shut- off device. WARNING: Vent - restriction devices should not be installed on emergencygenerator or heating - oil supply tanks. 7.4 Installa tion of Overfill Devices. Install overfill devices according to the manufacturer’s instructions. When installing an overfill
prevention device, refer to the gauging chart provided by the tank manufacturer to determine the correct distance below the tank t op for that device. Regulations specify that overfill devices may be installed at a percentage of tank capacity, not a percentage of tank diameter. When applicable, the thickness of double
-walled tanks and the height of manway covers above the tank primary

wall must be taken in consideration when determining the appropriate distance below the tank top to install an overfill device. [...] 

## 10. PIPING AND FITTINGS [Page20] [...] 10.13 Fill Piping. 

## [Page 24] Typically, 4
- inch diameter steel piping is used for fill
-pipe risers. Do not use nonmetallic piping for fill risers. If the fill riser or remote fill is isolated from ground, provide a grounding path for static electrical charges produced when fuel is delivered into the tank. Install a tight
- fill adapter on all fill pipes. Install the fill pipe so that the top of the fill cap will be between 4 and 6 inches below the manhole lid to allow the secure attachment of delivery adapters and clearance between the fill
pipe cap and the manhole cover. When inst alled, standard drop tubes should allow for at least 4 to 6 inches clearance from the tank bottom. If a flow diffuser is to be installed at the bottom of the drop tube, follow the manufacturer’s installation instructions. Remote fills should be used only when necessary. Remote
- fill piping should slope uniformly to the tank. Use caution when selecting overfill protection devices for use with remote fills. Refer to Sections 7.3.2 and 7.3.3 and manufacturer’s instructions. [...] 

## 13. ELECTRICAL INSTALLATI ON [Page 30] 13.1 Importance of Electrical Work. Performing electrical work associated with underground tank installations is critical to the prevention of environmental problems for the following reasons.  The defective installation of tank monitoring or leak
- detection system wiring may allow a release to remain undetected.  Conduit or other electrical apparatus placed against a surface that is protected against corrosion may cause damage to the coating or cathodic protection.  Electrical
- equipment install ers may damage the tank or piping while excavating, driving stakes, or otherwise performing their work.  Galvanic cathodic protection of metallic tanks or piping is impaired by grounding.  Failure to make the entry point of electrical conduit into tank
- top and dispenser sumps liquid tight can result in the release of product into the environment or the infiltration of water into the sump, causing leak
- detection systems to false alarm. 13.2 General Requirements. Ensure that all electrical equipment is instal led in accordance with applicable national, state, and local codes, including:  National Electrical Code , NFPA 70, National Fire Protection Association

### B
- 5

 Flammable and Combustible Liquids Code , NFPA 30, National Fire Protection Association  Automotive and Marine Service Station Code , NFPA 30A, National Fire Protection Association  Uniform Fire Code , Uniform Fire Code Association  International Fire Code , International Code Council Refer to Appendix C for more information concerning these documents. Equipment manufacturers may have electrical requirements that are more stringent than applicable electrical codes. Refer to the manufacturer’s electrical requirements before beginning electrical instillation. Separate electrical conduit and piping by at least 6 inches to avoid interference or damage cause by abrasion. Whenever possible, route electrical conduit away from piping. WARNING : Before working on any electrical circuit, be sure that the circuit is deenergized. Following Occupational Safety and Health Ad ministration (OSHA) lockout/tagout procedures as stated in 29 CFR 1910.147 to prevent accidental energizing of the circuit. 13.3 Leak- Detection and Cathodic - Protection Systems. Disconnecting power to an impressed
current cathodic
-protection system, or t o an electronic leak
- detection device, nullifies their effectiveness. Therefore, power provided to leak
- detection and impressed
- current cathodic
protection systems should not be normally be controlled by conventional switches. Nor should switches require for servicing these systems be readily available to unauthorized personnel. Power to the annunciator panels, alarms, controls, and other devices should also be protected from unauthorized disconnection. 

## 14. TESTING [Page 31] 14.1 System Tests. Tank an d piping tightness should be proven at various stages during the installation process. Recommended procedures for testing during installation are summarized in Tables 14
- 1 and 14
- 2. Also, establish that tanks, piping, secondary containment systems, leak
detection systems, overfill
-protection systems, [...] and line
- leak detectors are operating satisfactorily before the system is placed in operation. Recommended procedures for system start -up testing are summarized in Table 14
- 3. [...]

## 15. DOCUMENTATION AND TESTING [PAGE 32] 15.1 “As - Built” Drawings . Provide the owner with installation drawings (as
-builts) or photographs showing the location of underground piping, conduit, monitoring, equipment, and other significant system components. The owner should maintain these documents on file for as long as the storage system is in service.

API Recommended Practice 1615. 1996. “Installation of Underground Petrol eum Storage Systems.” American Petroleum Institute and Strategies for Today’s Environmental Partnership (STEP): Washington, D.C. Fifth edition. SECTION 1

– INTRODUCTION [PAGE 1] [...] 1.2 Purpose and Scope [...] 1.2.4 The primary application of this recommen ded practice is in connection with the underground storage of bulk petroleum products or used oil at retail and commercial facilities. It is not intended to cover specialized installations, such as fuel storage systems at marinas or airports, heating oil storage systems (residential or bulk), or systems installed inside buildings. This recommended practice does not apply to the installation of in ground of aboveground bulk storage. [...] 1.3 Defintions [PAGE 1] [...] [PAGE 3] 1.3.42 storage: The holding of a petroleum product in a container for later use. The term does not include collection of (a) overflows, drips, or spills in auxiliary containers (for example, sumps, catch basins, and drip
- collection devices) or (b) hydraulic fluids or similar substances w ithin machines (for example, hydraulic lifts and elevators). [...] [PAGE 4] 1.3.47 underground product pipes: Buried product lines connected to an underground storage tank. As used in this publication, underground product pipes do not include vent pipes, f ill pipes, or vapor recovery pipes. [...] SECTION 6

– EQUIPMENT PLACEMENT, ANCHORAGE, SECONDARY CONTAINMENT, AND BALLASTING [PAGE 13] [...] [PAGE 15] 6.3.2 Secondary containment can be provided by the following means: a. Impervious liners in the tank excav ation area. b. Impervious liners under lines (which should be drained to a sump in the tank excavation). c. Containment under dispenser (see Figure 6). d. Containment around submerged pumps (see Figure 6). e. Containment around fill manholes (see Figure 1 4, Section 9). [...] SECTION 7

– CORROSION PROTECTION [PAGE20] 7.1 General 7.1.1 In general the Environmental Protection Agency’s underground storage tank regulations contain the following requirements for each new tank and its piping: a. Underground storage tank system components that routinely carry product must be cathodically protected or constructed of noncorrosive material (for example, fiberglass or steel fiberglass
reinforced
-plastic composite). b. Cathodic protection systems must be designed, operated, and maintained in accordance with sound engineering practices and guidelines established by the authority having jurisdiction (see 7.6.2 and 7.6.3).

### B
- 8

c. The EPA allows for alternate methods on condition that the system is as protective of the enviro nment as other listed systems. One such system recently approved by the EPA and several state agencies is a tank system that isolates any unprotected corrosive metallic components from contact with the soil and/or groundwater. Note: Prior approval by th e authority having jurisdiction is required. 

### Corrosion protection is required for all parts of an USTS that are made of metal, that are in contact with the ground, and that routinely carry product, unless a corrosion expert certifies that it is not necess ary. Field
- installed cathodic protection systems must be designed by a corrosion expert. Inspection and recordkeeping requirement must be met (Refer to NACE RP 0285
- 95). [...] 7.4 Insulation of Exposed Surfaces [PAGE 22] 7.4.1 After all piping has been tested and found to be tight (see 10.2), all exposed threads of steel pipe should be coated with an appropriate dielectric material (see 7.3.5). This reduces the prospect of corrosion at threaded areas and premature pipe failure. Where a sacrificial
- anod e system has been installed, nonmetallic (for example, nylon) tank bushings may be installed in tank openings at all connection points to the tank (including pipe, gauge, and release detection equipment) to isolate said piping from separately protected tanks (see 7.3.4). [...] SECTION 9

– PIPING [PAGE 29] [...] 9.2.5 The vent piping for tall tanks should be adequately sized. This is necessary to prevent excessive pressure build up while the tank is being filled and to prevent vapor or liquid blowing back at t he fill opening when the unloading [PAGE 30] hose is disconnected. The maximum fill rate can be limited by the diameter of the vent line. Vents that are 2 inches in diameter (for up to 150 feet in length) should be adequate for flow rates incurred using 4
- inch delivery equipment (see NFPA 30). 9.7 Overfill Protection and Containment of Fill- Pipe Spills 9.7.1 Spills, drips, and overfills that occur during transfer operations from a delivery truck to the underground tank must be prevented or contained. 9 .7.2 To contain small spills around the tank fills, spill
- containment manholes must be installed (see Figure 14). Containment manholes can be purchases with a drain that routes any spilled product back into the underground tank. Other methods of fluid re moval are also available but are not as practical (for example, use of a hand pump, siphon, and/or bailing). The required size of containment manholes varies according to state and local regulations. 9.7.3 To prevent overfills, equipment must be installe d that will severely restrict or shut off the flow of product automatically or alert the operator in timely a fashion when an overflow is imminent. 9.7.4 Before transfer, the tank must be checked to ensure that sufficient volume is available. During tran sfer, the operation must be monitored continuously. [...] FIGURE 13 [PAGE 35] and [PAGE 36]: FIGURE 14 [PAGE 37] FIGURE 16 [PAGE 41]: [...]

## NewYork §613.3 Overfill prevention and secondary containment systems (a) Responsibility for transfer. The operator, w hen on the premises or when in control of a petroleum transfer, shall be responsible for transfer activities. If the operator is not on the premises or not in control of a petroleum transfer, the carrier will be responsible for transfer activities. The operator or carrier must em ploy practices for preventing transfer spills and accidental discharges. Prior to the transfer, the operator or carrier must determine that the receiving tank has available capacity to receive the volume of petroleum to be transferred. The operator or carrier must monitor every aspect of the delivery and must take immediate action to stop the flow of petroleum when the working capacity of the tank has been reached or should an equipment failure or emergency occur. (b) Color coding of fill ports. (1) Beginning five (5) years from the e ffective date of these regulations, the owner or operator must permanently mark all fill ports to identify the product inside the tank. These markings must be consistent with the color and symbol code of the American Petroleum Institute which follows. (2) The colors to be used are: (i) High gasoline Red (ii) Middle gasoline Blue (iii) Lower gasoline White (iv) High unleaded gasoline Red w /white cross (v) Middle unleaded gasoline Blue w/white cross (vi) Lower unleaded gasoline White w/black cross (vii ) Vapor recovery Orange (viii) Diesel Yellow (ix) #1 fuel oil Purple w

/yellow bar (x) #2 fuel oil Green (xi) Kerosene Brown (3) The symbols to be used are: (i) a circle for gasoline products and vapor recovery lines; (ii) hexagon for other distillates; and (iii) a border must be painted around fuel products containing extenders such as alcohol. The border will be black around a white symbol and white around all other colors. (4) Monitoring wells must be permanently marked and identified as a "moni toring well". (c) Requirements for valves, gauges and secondary containment systems. Within five (5) years of the effective date of these regulations, the owner must install the following. (1) Shutoff valves for remote pumping units at motor fuel dispens ers. All dispensers of motor fuel under pressure from a remote pumping system must be equipped with a shear valve (impact valve) which is located in the supply line at the inlet of the dispenser. This valve must be designed to close automatically in the ev ent that the dispenser is accidentally dislodged from the inlet pipe. A valve meeting the standards set forth in NFPA No. 30A, section 4
- 3.6 (see subdivision 613.1(g)) meets the requirements of this subdivision. (2) Shutoff valves for gravity
- fed motor fu el dispensers. All tanks which cause a gravity head on a dispenser of motor fuels must be equipped with a device such a s a solenoid valve which is positioned adjacent to and dow

nstream from the operating valve required in paragraph 613.3(c)(5). The valve m ust be installed and adjusted so that liquid cannot flow by gravity from the tank in case of piping or dispenser hose

failure. A valve meeting the standards set forth in NFPA 30A, section 2
- 1.7 (see subdivi si on 613.1(g)) meets the requirements of this subd ivision. (3) Gauges for aboveground storage tanks (i) All aboveground petroleum tanks must be equipped with a gauge which accurately shows the level of product in the tank. The gauge must be accessible to the carrier and be installed so it can be conveni ently read. (ii) The design capacity, working capacity and identification number of the tank must be clearly marked on the tank and at the gauge. (iii) A high level warning alarm, a high level liquid pump cutoff controller or equivalent device may be use d in lieu of the gauge required above. (4) Check valve for pump
- filled tanks. All fill pipes leading to a pump
- filled petroleum tank must be equipped with a properly functioning check valve or equivalent device which provides automatic protection against backflow. A check valve is required only when the piping arrangement of the fill pipe in such that backflow from the receiving tank is possible. (5) Operating valves for gravity
- drained tank. Each tanks connection through which petroleum can normally flow must be equipped with an operating valve to control the flow. A valve which meets the standards set forth in NFPA No. 30, section 2
- 2.71.1 (see subdivision 613.1(g)) meets the requirements of this paragraph. (6) Secondary containment system for abovegr ound tanks. (i) A secondary containment system must be installed around any aboveground petroleum storage tank which: (a) could reasonably be expected to discharge petroleum to the waters of the state, or (b) which has a capacity of ten thousand (10,000 ) gallons or more. The secondary containment system must be constructed so that spills of petroleum and chemical components of petroleum will not permeate, drain, infiltrate or otherwise escape to the groundwaters or surface waters before cleanup occurs. T he secondary containment system may consist of a combination of dikes, liners, pads, ponds, impoundments, curbs, ditches, sumps, receiving tanks and other equipment capable of containing the product stored. Construction of diking and the storage capacity o f the diked area must be in accordance with NFPA No. 30, section 2
- 2.3.3 (see subdivision 613.1. (g)). (ii) If soil is used for the secondary containment system, it must be of such character that any spill onto the soil will be readily recoverable and wil l result in a minimal amount of soil contamination. (iii) Storm water which collects within the secondary containment system must be controlled by a manually operated pump or siphon, or a gravity drain pipe which has two manually controlled dike valves, o ne on each side of the dike. All pumps, siphons and valves must be properly maintained and kept in good condition. If gravity drain pipes are used, all dike valves must be locked in a closed position except when the operator is in the process of draining c lean water from the diked area. (iv) Storm water or any other discharge at a facility must be uncontaminated and free of sheen prior to discharge. Storm water which is contaminated must be treated to reduce petroleum concentration to 15 parts per million o r less and to remove any visible sheen prior to discharge. Additional requirements may be imposed under 6 NYCRR Parts 751
- 758 for protection of the state's waters. (d) Maintenance of spill prevention equipment. The owner or operator must keep all gauges, valves and other equipment for spill prevention in good working order.

- level alarm; or (C) Restrict flow thirty minutes prior to overfilling, alert the operator with a high level alarm one minute before overfilling, or automatically shut off flow into the tank so that none of the fittings located on top of the tank are exposed to regulated substances due to overfilling. Note: Overflow prevention equipment that will automatically shut off or restrict flow into the t ank should not be used where a pressurized fuel transfer system may be employed since an overflow may occur when the flow is suddenly shut off or restricted. (b) Owners and operators are not required to use the spill and overfill prevention equipment speci fied in subsection (3)(a) of this section if: [12] (i) Alternative equipment is used that is determined by the department or delegated agency to be no less protective of human health and the environment than the equipment specified in subsection (3)(a)(i ) or (ii) of this section; or (ii) The UST system is filled by transfers of no more than twenty
- five gallons at one time. [12] 173
