Chapter 10A: Aboveground Storage Tank Management Procedure

1. Purpose

This procedure establishes the requirements for the management of aboveground storage tank (AST) systems at Fort Greely Alaska (FGA). Tanks are used to store petroleum, oil, lubricants and hazardous materials. This procedure assures that tank storage will be conducted in compliance with federal, state and U.S. Army requirements.

2. Scope

This procedure applies to all aboveground storage tanks at FGA to include inspections, maintenance, leak detection, spill and overfill prevention, corrosion protection, and construction and modification of tanks. The requirements of this procedure apply to aboveground tanks and containers ≥55 gallons (including mobile fueling sources) and to associated piping, secondary containment, and ancillary equipment. Fifty-five gallon drums have been added to this procedure to make it consistent with the U.S. EPA’s Spill Prevention, Control, and Countermeasure regulations which defines bulk storage containers (tanks) as containers ≥ 55 gallons. This procedure does not apply to the operational use of fluids (hydraulic systems, lubricating systems, gear boxes, machining coolant systems, heat transfer systems, transformers, circuit breakers, electrical switches, other systems containing oil solely to enable the operation of the device) and vehicle fuel tanks.

3. Responsibilities

a. Garrison Commander The Garrison Commander is the responsible official for environmental compliance at Fort Greely and provides overall policy and guidance associated with environmental compliance.

The Commander will consult regularly with FGA-ENV to ensure the installation’s environmental policies and procedures are consistent with federal, state and Army requirements and are properly implemented. The Commander will consult regularly with all installation tenant organizations and departments and facilitate resolution of conflicts regarding environmental matters that cannot be resolved at lower levels.

b. FGA Environmental Office (FGA ENV) The FGA Environmental Office, part of the Fort Greely Directorate of Public Works, is responsible for establishing environmental procedures that apply to all activities conducted at FGA. The FGA ENV:

(1) Oversees tank management operations for environmental compliance.

(2) Submits all required reports and documents to regulatory agencies and serves as

FGA’s primary point of contact on environmental compliance.

(3) Advises the garrison, tenants and contractors of environmental requirements and provides assistance achieving compliance.

(4) Provides annual tank management training.

(5) Maintains this procedure, the Spill Prevention Response Plan, and the FGA tank inventory (Attachment 1).

(6) Coordinates the internal and external tank, pipeline and cathodic protection system inspections and testing. (The DESC will schedule inspections and testing for tank systems within the FGA Bulk Fuel Farm)

c. Installation Management Command (IMCOM) – Pacific The IMCOM - Pacific oversees environmental management and compliance activities at FGA and provides resources for environmental program implementation. The IMCOM - Pacific ensures Fort Greely’s environmental program conforms to DoD and Army requirements and provides policy and programmatic guidance to FGA-ENV.

d. FGA Directorates, Tenants and Contractors FGA directorates, tenants and contractors will designate aboveground tank operators that are responsible for meeting the requirements of this procedure for all aboveground tank systems that are under their control. A listing of responsible directorates, tenants and contractors for each aboveground tank system is provided in Attachment 1. Directorates, tenants and contractors are responsible to provide adequate funding to operate and maintain aboveground fuel storage tank equipment in accordance with this procedure.

4. Spill Notification and Response

If a spill from a tank is discovered or suspected, the operator will immediately provide verbal notification to the FGA Fire Department at (907) 873-3473 (911 for on-base lines) and conduct response activities according to Chapter 5 of the FGA Environmental Procedures Manual.

5. Inspection and Testing

(1) Tank operators must conduct weekly tank inspections of all tanks ≥ 100 gallons using the inspection form in Attachment 2 (an inspection is not required for a tank that is permanently out of service). Copies of completed inspection forms should be regularly sent to the FGA Environmental Office.

(2) Small bulk oil storage containers (55 gallons to 100 gallons) must be inspected monthly using the inspection form in Attachment 3. Copies of the completed inspection forms should be regularly sent to the FGA Environmental Office.

(3) FGA ENV will ensure that external inspections, internal integrity testing and piping inspections are conducted by an Alaska Department of Environmental Conservation (ADEC) certified inspector according to the schedule in Attachment 1.

(4) For tanks in direct contact with the ground that have impressed current cathodic protection system, rectifier readings must be recorded monthly by the operator and tested annually by an ADEC certified tester.

6. Operations, Maintenance and Repair

(1) Operators must ensure that the drain valves permitting direct outward flow of the container's contents have adequate security measures (locks, controlled access) so that they remain in the closed position when not in use.

(2) Operators will label tanks with contents and place "No Smoking", "Authorized Personnel Only" and the ADEC-approved spill reporting sign (Attachment 4) on or near the aboveground tank system and replace faded or illegible signs.

(3) Tank operators must coordinate all tank system repairs, beyond preventative maintenance, with the FGA ENV to ensure the repairs will take precautions to prevent a release and retrofits will meet regulatory and Army requirements.

(4) Metal pipe sections and fittings that have leaked as a result of corrosion or other damage must be replaced.

7. Filling or Off-loading

(1) Operators will ensure tank level is tested before filling to make certain adequate capacity exists.

(2) The operator or refueler must check all fittings before filling or off-loading tanks.

Aboveground Storage Tank Management Procedure January 2008

[Printed Copies of this Document for Operational Use Only – Controlled Electronic Document Available from DPW Environmental Office]

Vents must be checked for icing that would prevent proper ventilation.

(3) The operator or designated refueler will monitor transfer operations to ensure that:

(a) A release due to spilling or overfilling does not occur;

(b) The volume available in the tank is greater than the volume of petroleum to be transferred to the tank before the transfer is made;

(c) The transfer operation is constantly monitored to prevent overfilling or spilling; and

(d) Any spill or overfill is reported immediately.

(4) To prevent spilling and overfilling during transfer operations, the operator will use the following spill and overfill prevention equipment:

(a) Spill prevention equipment, such as a spill catchment basin, that will prevent release of the petroleum to the environment when the transfer hose is detached from the fill pipe; and

(b) Overfill prevention equipment that will automatically shut off flow into the tank when the tank is no more than 95 percent full; or alert the transfer operator when the tank is no more than 90 percent full by restricting the flow into the tank or by triggering a high-level alarm.

(5) After filling or off-loading fuel, the fueler or operator will cap all truck manifolds.

(6) Refuelers that are stored at Ft. Greely with fuel must be parked in a containment area.

(7) Loading/unloading stands must be constructed with a volume of containment greater than or equal to the largest tanker fuel compartment.

8. Tank Construction, Modification, Change in Service and Closure

(1) All tank construction, modification and closure must be preapproved by the FGA

ENV. Also, if a tank is taken out of service for more than three months, the FGA ENV must be notified.

(2) New tanks installed at Ft. Greely that are <10k gallons must meet the following requirements:

(a) New tanks will be aboveground, unless conditions exist that make aboveground construction impractical or cost prohibitive.

(b) Tanks must be constructed to prevent a release caused by corrosion or structural failure for the operational life of the system.

(c) Tanks must have a means of secondary containment. (To the extent economically and technically feasible, new tanks should be of double walled

(d) Cathodic protection must be installed to protect tank bottom if installed on the soil.

(e) Each tank must be constructed with at least one of the following devices to avoid discharges: high level alarm, high level pump cutoff device, direct audible communication between the container gauger and the pumper, and/or a fast response system for determining the liquid level.

(f) Facility lighting is necessary if needed to discover discharges occurring during hours of darkness.

(g) Piping should be aboveground to the extent possible to allow visual leak detection. If buried piping is necessary, it must be off all welded construction and protected from corrosion by a cathodic protection system.

(h) Piping supports must be designed to be seismically stable and composed of materials to minimize corrosion and prevent chafing and allow for expansion and contraction.

(i) Aboveground piping must be protected from damage by vehicles.

(3) In addition to the requirements above, new tanks installed at Ft. Greely that are

≥10k gallons must additionally meet the following requirements:

(a) Each tank must have a leak detection system that an observer from outside the tank can use to detect leaks in the bottom of the tank.

(b) Each tank must have an overfill prevention system which can be a high level alarm to signal personnel conducting a transfer or a high level automatic pump shutoff device to stop flow at a predetermined tank content level or both.

(c) Fuel spills from overfilling must be directed to the tank’s interstitial space or secondary containment structure.

(d) Fuel can not be added to the tank until the tank has been added to the Ft.

Greely Spill Prevention and Response Plan and approved by the ADEC.

(e) Field built tanks must be constructed and installed using:
