SPCC Comments (POC: Fritz Miller, 656-3106, or frederick.j.miller42.civ@mail.mil)

Ensure all new oil storage tanks and fuel tanks are compliant with the Environmental Protection Agency’s Spill Prevention Controls and Countermeasures (SPCC) regulation found in 40 CFR

112. This includes, but is not limited to, secondary containment, overfill protection devices, and primary and emergency venting. USAG-HI SPCC Plan Appendix F, Design Construction and Installation Requirements for Factory/Shop Fabricated Aboveground Storage Tanks provides details of all fuel/oil tank requirements.

Consider constructing a permanent fuel truck/modular fuel system parking area to provide the secondary containment required by EPA regulations. The containment would need to hold 110% of largest tank (3300 gal) in the storage area. The containment would require a manually operated drain valve to release water after it is inspected to ensure there is no fuel.

3.0. Definitions.

3.1. Aboveground Storage Tank (AST). A tank or container designed to operate at pressures ranging from atmospheric pressure through a gauge pressure of one psig measured at the top of the tank. The tank may be sitting on the ground or set on supports, such as saddles, skids or legs, etc., and

(Am-0003)

Section 01 57 19 Attachment Page 15 https://www.garrison.hawaii.army.mil/sustainability/SpillPreventionResponse.aspx may be installed in a vault. Included are shop- abricated tanks, field-erected tanks, and portable containers with a capacity of 55 U.S. gallons (208 liters) or greater. [Ref.: STI SP001]

3.2. Anti-siphon valve. A device to prevent any siphoning due to damaged fuel lines, broken pumps, leaky or leaking fuel pumps. This device is not a check valve. [Ref.: STI SP001]

3.3. Continuous Release Detection Method (CRDM) – A means of detecting a release of liquid through inherent design. CRDM is passive because it does not require sensors or power to operate.

Liquid releases are visually detected by facility operators. The system shall be designed in accordance with good engineering practice. Several acceptable and commonly used CRDM systems are as follows:

• Release prevention barrier (RPB) (described in definition of release prevention barrier).

• Secondary containment AST, including double-wall AST or double-bottom AST.

• Elevated AST, with or without release prevention barrier. [Ref.: STI SP001]

3.4. Factory/Shop-fabricated AST - Is a welded metal AST fabricated in a manufacturing facility, or an AST not otherwise identified as field-erected, with a volume less than or equal to 50,000 U.S.

gallons (189,271 liters). [Ref.: STI SP001]

3.5. Double Wall AST (Secondary Containment Tank). A tank that has an inner and outer wall with an interstitial space (annulus) between the walls and that has a means for monitoring the interstitial space for a leak. The tank may also be constructed with an integral secondary containment dike such as pans, boxes or containers designed to contain the contents of the primary tank if the primary tank fails. A secondary containment AST may be open or closed to the atmosphere. If precipitation cannot readily enter the integral secondary containment, then the containment need only be sized for the primary tank volume. If precipitation can enter the secondary containment, then the secondary containment is sized to contain the primary tank volume and with sufficient freeboard to contain precipitation. [Ref.: 40 CFR 112.8(c)(2); 2015 NFPA 30.3.3.51.5; STI SP001]

3.6. Leak Gauge. A leak gauge is designed for use on AST’s that have a double wall containment.

The gauge top mounts to a monitoring pipe or over the top of the interstitial space, it is designed to monitor the bottom of that space and visually alert the owner/operator of any liquid that may get into the secondary containment. A standard float type gauge is acceptable. [Ref.: STI SP001]

3.7. Liquid Level Gauge. A device that is easily readable that automatically indicates the actual fuel level in the AST. A standard float type gauge is acceptable. [Ref.: STI SP001]

3.8. Overfill Protection Device (Spill Bucket). Systems, procedures, or devices used to prevent liquid in ASTs from running over or spilling out of the AST during the filling process. A person who is physically present and in control of a shutoff device during the entire tank filling process is an acceptable procedure to achieve overfill protection. For USTs, spill buckets shall have a 5-gallon minimum storage capacity and shall be double wall construction. [Ref.: 40 CFR 112.8(c)(8)(i-v); 40

CFR 280.30; HAR 11-281; STI SP001]

Section 01 57 19 Attachment Page 16

3.9. Release Prevention Barrier (RPB) – A liquid containment barrier that is installed under the

AST. Its purpose is to divert leaks toward the perimeter of the AST where they can be easily detected, as well as to prevent liquid from contaminating the environment. RPBs are composed of materials compatible with the liquid stored in the AST and meet appropriate engineering standards.

Examples are steel (as in steel doublebottom tanks), concrete, elastomeric liners or other suitable materials, provided the above criteria are met. [Ref.: STI SP001]

3.10. Vents.

3.10.1. Emergency Relief Vent. An opening, construction method, or device that will automatically relieve excessive internal pressure due to an exposure fire. [Ref.: 2015 NFPA 30.3.3.60.1]

3.10.2. Normal (Primary) Vent. An opening, construction method, or device that allows the relief of excessive internal pressure or vacuum during normal storage and operations. As a minimum size, all normal vents shall be at least 1-¼ inches in inside diameter. It must have a bug proof, rain cap secured on top of the vent. The vent must be at least 3 feet higher than the highest point within a 10-foot radius of the ATS. [Ref.: 2015 NFPA 30.3.3.60.2; STI SP001]

4.0. Approval Process.

4.1. Underground Storage Tanks (USTs) and stationary Aboveground Storage Tanks (ASTs) shall not be installed on USAG-HI and its sub-installations without prior approval from the DPW.

4.2. Proponents of new constructions, repair or replacement of stationary storage tank projects must submit a Facilities Engineering Work Request (FEWR) to the DPW and a Record of Environmental

Consideration (REC), IMPC-HI-PW Form 29, Jul 07, to the DPW Environmental Division (ED) for review and approval before execution of the project. All designs, installations, replacements, upgrades and repairs of aboveground and underground storage tanks, their associated piping and monitoring equipment must be reviewed and approved by the DPW-ED as part of the REC process.

4.3. A copy of the tank system design and as built drawings must be provided to the DPW-ED for record keeping in accordance with 40 CFR 112.8 and the STI SP001 standard.

4.4. USAG-HI requires, whenever feasible, that preference to install elevated, double wall ASTs equipped with Continuous Release Detection Method (CRDM) instead of USTs be given in all new tank installations. While the short-term cost may be higher, the long-term total cost of ownership of

ASTs compared to USTs is typically much lower due to fewer incidents, environmental cleanups and regulatory citations. Furthermore, when comparing inspection requirements for underground tanks to aboveground tanks, the visual inspection of elevated ASTs is considerably simpler and less costly than conducting the tests required on USTs.

4.5. In accordance with Army Regulation (AR) 200-1, USAG-HI does not allow the installation of

USTs for the purpose of storing used oil. If permitted by the DPW for new POL products, USTs shall be double-walled steel fiberglass reinforced with interstitial monitoring and automatic tank gauging and cathodically protected. [Ref.: 40 CFR 280; HAR 281]

(Am-0003)

Section 01 57 19 Attachment Page 17

4.6. Used POL stored in ASTs must meet the requirements of this document plus additional applicable requirements of the Resource Conservation and Recovery Act (RCRA) regulation for used oil management and storage as codified in 40 CFR 279.22.

5.0. General AST Construction Requirements.

5.1. Aboveground petroleum fuel tanks shall conform to all Federal, State, Local regulations and guidelines, and with the requirements described in this document. This includes indoors and outdoors tanks for permanent placement as part of new construction, as replacement of existing storage tank systems, day tanks and base fuel tank on emergency standby generators, and tanks used for temporary storage by construction contractors and military units.

5.2. ASTs, including generator base tanks, must be made of steel and Underwriters Laboratories

(UL) listed. Acceptable UL standards for flammable liquids in ASTs are: UL 142, Standard for Steel

Aboveground Tanks for Flammable and Combustible Liquids; UL 2080 Standard for Fire Resistant

Tanks for Flammable and Combustible Liquids; or UL 2085, Standard for Protected Aboveground

Tanks for Flammable and Combustible. [Ref.: 2015 NFPA 30.21.4.2.1.1; 29 CFR

1910.106(b)(1)(i)(a); STI SP001]

5.3. Each major component of the tank system shall have a nameplate secured or stamped to the equipment with the manufacturer's name, type or style, model or serial number, storage capacity, and rating number.

1910.106(g)(3)(iv)(d); 2015 NFPA 30.22.11.4.7; 2015 NFPA 30.22.15]

8.0. Tank Containment.

8.1. ASTs and their associated external piping aboveground or underground must be secondarily contained. Double wall construction is preferred. [Ref.: 40 CFR 112.8(b)(3); 40 CFR 112.8(c)(2);

40 CFR 112.8(d)(1); 2015 NFPA 30.22.11].

Section 01 57 19 Attachment Page 19

8.2. ASTs shall be double-walled type tanks unless a single wall tank installation is approved by the

DPW. While single wall storage tanks designed with an external sized secondary containment is acceptable under 40 CFR 112.8, preference to double wall tanks will be given, whenever possible, in order to reduce the potential for a catastrophic tank failure and to also reduce the long term maintenance cost of the tank and secondary containment structure. Corrosion damage to tanks in

Hawaii is dramatically accelerated and the tank life expectancy is significantly reduced due to the

Island’s tropical climate which includes a combination of humidity/rain and constant exposure to salt-laden air. While the upfront cost of double wall ASTs is higher, the long-term potential risks to the environment and cost of ownership is significantly reduced and therefore preferred.

8.3. In cases where a single wall tank construction is approved, USAG-HI requires that the external secondary containment/dike be impervious and capable of holding the entire content of the largest container plus an additional ten percent to allow for rain if precipitation can enter the secondary containment. Secondary containment can also serve as overfill spill protection for tank fill ports not equipped with a spill bucket. [Ref.: 40 CFR 112.8(c)(2)]

8.4 The containment drainage shall be equipped with traps or separator if it discharges into public waterways or if it is connected to the public sewers. [Ref.: 29 CFR 1910.106(e)(3)(iv)(b); 29 CFR

9.0. Tank Foundation and Support.

9.1. ASTs shall rest on the ground or on foundations made of concrete, masonry, piling, or steel.

Tank foundations shall be designed to minimize the possibility of uneven settling of the tank and to minimize corrosion in any part of the tank resting on the foundation. The bearing capacity of the foundation for the tank must be designed in accordance with the manufacturer’s recommendations and must be able to support the tank plus the weight of the maximum amount of product the tank will be storing. [Ref.: 2015 NFPA 30.22.5.2.1; 2015 NFPA 30.22.5.2.2]

9.2. The tank must be securely anchored with hold down restraints to resist natural disasters. [Ref.:

2015 NFPA 30 4.2.4.3; 2015 NFPA 30.19.7.3.2.2; 2015 NFPA 30.21.6.3(2); 2015 NFPA 30.22.5.1.3;

29 CFR 1910.106(b)(5)(vii); STI SP001 Para 1.6, Para 10.3]

9.3. The tank foundation design must include provisions for draining surface water away from the tank to minimize corrosion and the risk of fuel accumulation under the tank from an overfill or spill.

[Ref.: 2015 NFPA 30.15.3.5.1; 29 CFR 1910.106(d)(6)(iii)]

10.0. Leak Detection.

10.1 Double wall tanks and piping must be provided with means to detect leaks such as a direct vision leak gauge and/or leak sensor/alarm. Note: Elevated single wall ASTs do not require a release prevention barrier (in addition to secondary containment) to qualify as a Category 1 tank, as leaks from elevated tanks are visible.

13.2. Single wall ASTs must have one normal atmospheric vent and one emergency vent or other acceptable form of construction or device that will relieve excessive internal pressure caused by exposure to fires. This requirement also applies to each compartment of a compartmented tank and tanks with closed top dike construction. Double wall ASTs must have an emergency vent for the interstitial space in addition to the normal and emergency vents required for the primary tank. [Ref.:

2015 NFPA 30.21.4.3.3.1 through 30.21.4.3.3.12; 2015 NFPA 30.22.7.1.1.1]

13.3. Emergency venting device for secondary containment (interstice) is not required on Convault tank per the manufacturer’s tank form of construction and design. Acceptable under 2015 NFPA

30.22.7.1.1. [Ref.: 2015 NFPA 30.21.4.3.4; 2015 NFPA 30.22.7.1.1.1]

13.4. Normal/primary vents shall be sized in accordance with either API Standard 2000, Venting

Atmospheric and Low-Pressure Storage Tanks, or another approved standard. Alternatively, the normal vent shall be at least as large as the largest filling or withdrawal connection, but in no case shall it be less than 1.25 in. (32 mm) nominal inside diameter. [Ref.: 2015 NFPA 30.21.4.3.3; STI

Where vent pipe outlets are adjacent to building or public ways, they shall be located so that the vapors are released at a safe point outside of buildings and not less than 12 ft. above the adjacent ground level. In order to aid their dispersion, vapors shall be discharged upward or horizontally away from closely adjacent walls. Vent outlets shall be located so eaves will not trap the flammable vapors or other obstructions and shall be at least 5 ft. from building openings and at least 15 ft. (4.5 m) from powered ventilation air intake devices. [Ref.: 2015 NFPA 30.27.8.1.1 through NFPA 30.27.8.1.3]

15.4. Anti-siphon valve must be provided to prevent a release from the tank by siphon flow where the liquid level in the tank is higher than the elevation of the dispenser thereby producing gravity head on the dispending unit or any of the product piping. Such a valve must be positioned in the tank’s discharge pipe, downstream from the block valve that is located just outside the tank shell and so adjusted that liquid cannot flow by gravity from the tank in case of piping or hose failure. Anti-siphon valves must be designed to remain in a closed position, thus preventing the flow of liquid except when some positive action, such as turning on the pump, is taken. An anti-siphon valve may operate on the solenoid principle. Others are spring-loaded check valves. Both shall be designed to open only when the pump is operating.
