[]{#__RefHeading___Toc502626682 .anchor}b. SITE DESCRIPTION AND
OPERATIONS

This section describes the site and its operations.

1.  []{#__RefHeading___Toc502626683 .anchor}Facility Location, Layout,
    and Operations

    The facility is located in Pulaski County, Arkansas, just northwest
    of the North Little Rock Municipal Airport (Figure 1). Figure 2
    shows the layout of the facility, including the location of a
    1,000-gallon aboveground storage tank (AST) and a 19-gallon
    aboveground day tank. The fuel in the AST is pumped to the 19-gallon
    aboveground day tank, which is connected to a emergency backup power
    (electric) generator. The day tank and generator are located in the
    enclosed generator building.

    The estimated fuel usage is approximately 360 gallons per month.
    This estimate is based on an average of the fuel purchased during
    the last 8 months of operation. Fuel consumption increases based on
    the frequency and duration of any power outages.

2.  []{#__RefHeading___Toc502626684 .anchor}Facility Storage

    The single-walled, welded steel plate AST is cylindrical in shape
    and horizontally situated. The AST is located in an open-top steel
    rectangular secondary containment bin. The secondary containment bin
    is equipped with a drain valve and has a total containment capacity
    of 1,300 gallons. This bin, when properly operated, should contain
    any overfills during refueling and, therefore, an automatic shut-off
    valve is not required.

    The AST is connected to a pump on top of the day tank via a single
    supply line. The supply line is constructed of steel pipe and is
    equipped with a shut-off valve and backflow preventer. The supply
    line is not equipped with any type of secondary containment system.
    This pump moves fuel from the AST into the day tank. The day tank is
    a single-walled rectangular steel tank set in an open top spill pan
    (rupture basin). The day tank is connected to the generator by
    flexible rubber supply and return lines. Table 1 summarizes the
    pertinent information on the tanks at the facility.

3.  []{#__RefHeading___Toc502626685 .anchor}Drainage Pathway and
    Distance to Navigable Waters

    Any fuel oil spilled from the AST or the day tank would flow
    northeast to the airport parking area (Figure 2). Drainage from the
    airport parking area flows north to an unnamed tributary of the
    Arkansas River.

4.  []{#__RefHeading___Toc502626686 .anchor}Spill History

    [Reportable Spill events from 1974 to the date on the cover of this
    plan:]{.underline}

    None

5.  []{#__RefHeading___Toc502626687 .anchor}Spill Potential, Volumes,
    and Rates

The most probable causes of spills from the AST are from either
overfilling, a ruptured hose during fuel unloading, or from failure of
the fuel supply line to the day tank. For the AST, spills caused by loss
of structural integrity, vehicle collisions, or earthquakes are
low-probability events. The probable causes of spills for the day tank
are from a failure of the pump to shut down or failure of the line from
the pump to the day tank.

Table 2 summarizes the potential type of failure, potential spill
volume, estimated rate, and direction of spill flow from the tanks.

[]{#__RefHeading___Toc502626688 .anchor}PART II - DESIGN COMPONENTS AND
OPERATIONAL PROCEDURES FOR SPILL PREVENTION AND CONTROL

This section discusses spill prevention and control measures that shall
be implemented at the facility.

A.  []{#__RefHeading___Toc502626689 .anchor}SPILL PREVENTION

This section describes design components and operating procedures that
shall be implemented at the facility to prevent oil spills.

1.  []{#__RefHeading___Toc502626690 .anchor}Bulk Storage Tanks and
    Facility Transfer Operations

    [AST:]{.underline} The AST construction shall be compatible with the
    diesel fuel held by the AST. The AST shall be located in a secondary
    containment bin with a capacity to store at least 110 percent of the
    volume of the AST.

    The AST shall not be filled to more than 90 percent of capacity. The
    filling of the AST shall be monitored full time by the fuel supply
    contractor and a NWS representative.

    [Day Tank:]{.underline} This tank shall have an open top spill pan
    (rupture basin) designed to hold 110 percent of the tank volume. It
    shall have a liquid level gauge to indicate the amount of fuel in
    the tank (empty to full) and a high-level float switch connected to
    the audible alarm to warn of overfilling. The rupture basin shall
    have a float switch designed to detect fuel that has spilled or
    leaked. The float switch shall be connected to the audible alarm
    system.

    [Piping:]{.underline} The portion of piping located underground
    shall be wrapped or coated to prevent corrosion. An antisiphoning
    valve shall be located between the AST and the pump to prevent
    unwanted fuel from being siphoned from the AST.

2.  []{#__RefHeading___Toc502626691 .anchor}Tanker Truck Unloading
    Operations

All delivery drivers shall have U.S. Department of Transportation
hazardous material transportation training as required by Federal law.

The remainder of this section discusses the procedures that shall be
used during unloading of fuel from the tanker truck into the AST to
prevent spills. This procedure shall be documented every time refueling
occurs using the form found in Appendix A. Copies of this form shall be
kept for 3 years.

The following procedure shall be used [before]{.underline} fuel
unloading:

-   Ensure that the high-level alarm system is functioning properly.

-   A NWS representative should determine the available capacity
    (ullage) of the AST by measuring the depth of the fuel in the AST
    and converting the reading to gallons (See Appendix A). This ullage
    is communicated to the fuel supply contractor and marked in the
    fueling log.

-   Move spill containment equipment such as booms or spill barriers
    into the unloading area.

-   Block the tanker truck wheels.

-   Place drip pans under all pump hose fittings (if applicable) before
    unloading.

-   The NWS representative and the delivery driver ensure the fill
    nozzle is placed in the appropriate AST appurtenance.

    Both the NWS representative and the delivery driver shall remain
    with the vehicle at all times during unloading. Gauges on the truck
    shall be continuously monitored to ensure the ullage is not
    exceeded.

    The following procedure shall be used after fuel unloading is
    completed:

-   Record the amount of fuel transferred to the AST in the log
    (Appendix A).

-   Drain the fill hose and then ensure that all drain valves are closed
    (if applicable) before removal of the hose from the AST.

-   Pour any fuel in the drip pans, tanker truck containment pool, or
    secondary containment bin into the AST (if it has the capacity) or
    dispose of appropriately.

-   Inspect the tanker truck before removing the blocks to ensure the
    lines have been disconnected from the AST.

-   Remove the blocks from truck wheels.

-   Place a copy of the fuel-unloading checklist in the SPCC plan.

    []{#__RefHeading___Toc502626692 .anchor}3. Inspections and Records

[Inspection and Maintenance of Tanks]{.underline}: The AST and generator
day tank shall be inspected weekly for any oil outside the tank,
especially at seams (including the underside). The outside of exposed
piping shall also be inspected weekly, especially at the joints such as
gasketed fittings. Monthly and annual inspections shall follow the
checklists shown in Appendix B.

[Record Keeping]{.underline}: The Environmental/Safety Focal Point
(person responsible for spill prevention at the facility) shall be
responsible for completing the ullage logs and documentation of fuel
unloading procedures. These records as well as records of all
inspections shall be maintained for at least 3 years from the time of
inspection.

[]{#__RefHeading___Toc502626693 .anchor}4. Site Security

The AST shall have adequate lighting to detect spills at night and a
security fence with a locked gate to prevent tank damage or spills
caused by vandalism. The generator building shall be kept locked.
Signage around the AST shall warn of the presence of a combustible
liquid, that the combustible liquid is diesel fuel, and that smoking is
not permitted near the AST. A fire extinguisher shall be located in the
adjacent generator enclosure. The AST is not located in the direct line
of parking lot traffic; therefore, no guard posts are required.

[]{#__RefHeading___Toc502626694 .anchor}5. Training

The Environmental/Safety Focal Point and an alternate shall be trained
in the intent of applicable oil spill regulations and methods for
implementing the inspection and maintenance procedures outlined in the
previous paragraph. Spill control and countermeasure shall also be
included in the training. An outline for the training is found in
Appendix C.

Training shall be repeated once per year. All new personnel responsible
for implementing this SPCC plan shall be properly trained before
beginning the new position. A record of who was trained, when, and by
whom, shall be filed with this SPCC plan and kept for a period of 3
years.

[]{#__RefHeading___Toc502626695 .anchor}B. sPILL CONTROL

This section describes control measures that shall be implemented to
prevent any spilled oil from entering navigable waters or adjoining
shorelines.

1.  []{#__RefHeading___Toc502626696 .anchor}Secondary Containment
    Designs, Construction Material, and Volume

    The secondary containment structures for the AST and the generator
    day tank shall be sized to contain a minimum of 110 percent of the
    tank volumes. The AST secondary containment shall have a drain valve
    that is normally closed for the drainage of storm water from the
    containment area. The day tank rupture basin shall have a float
    switch designed to detect fuel that has spilled or leaked. The float
    switch shall be connected to the audible alarm system.

2.  []{#__RefHeading___Toc502626697 .anchor}Spill Kits Type and Location

The facility shall have spill kits designed absorb diesel fuel and to
divert a spill from navigable waters. These items shall be stored in the
generator shed or nearby. The kit shall include oil absorbent socks and
mats in a polyethylene container that doubles as a disposal container.
In addition, urethane spill barriers that can divert or contain a
relatively small spill and prevent it from reaching navigable waters
should be included with the spill kit.

[]{#__RefHeading___Toc502626698 .anchor}PART III - SPILL COUNTERMEASURES
AND REPORTING

The primary emphasis of this SPCC plan is prevention. The spill
countermeasures presented do [not]{.underline} constitute a contingency
plan detailed in Title 40 of the Code of Federal Regulations (40 CFR)
Part 109, nor is one required. Such a plan is only required under 40 CFR
Part 112.7(d) if it is impracticable to provide containment,
diversionary structures, or equipment to prevent the discharge of oil to
navigable waters. In addition, this facility is not required to have a
facility response plan under 40 CFR Part 112.20 since at least one of
the following statements is true:

-   The facility does not transfer oil over water from vessels and have
    a total oil storage capacity of greater than or equal to 42,000
    gallons

-   The facility does not have a total storage capacity over 1 million
    gallons.

Should a spill occur, the following measures would be implemented:

A.  []{#__RefHeading___Toc502626699 .anchor}SPILL COUNTERMEASURES

> This section presents countermeasures to contain, clean up, and
> mitigate the effects of an oil spill that impacts navigable waters or
> adjacent shorelines.
>
> A spill containment and cleanup activity will never take precedence
> over the safety of personnel. No countermeasure activities will be
> undertaken until conditions are safe for workers. The following
> general procedures should be implemented as countermeasures:

1.  Account for all personnel and ensure their safety.

2.  Eliminate all ignition sources in the immediate area.

3.  Attempt to divert flow from leaving the facility with a spill
    barrier or the contents of spill kit.

4.  Attempt to seal or somehow stop leak if it can be done safely.

5.  Notify contacts and emergency response contractor as described in
    the following section for assistance in control and cleanup.

[]{#__RefHeading___Toc502626700 .anchor}B. SPILL REPORTING

This section discusses the reporting procedures for spills of diesel
fuel at the facility. The people and organizations notified vary based
on the quantity of the spill, whether it reaches navigable waters or
adjoining shorelines, and the frequency of spills.

A spill reporting form that requests the information to be reported to
all agencies (to the extent known) is included in Appendix D. Copies of
the completed form should be sent to the NWS Environmental Compliance
Officer and the National Oceanic and Atmospheric Administration (NOAA)
Southern Regional Compliance Officer (see following section).

1.  []{#__RefHeading___Toc502626701 .anchor}General Notification
    Procedures For All Spills

The responsible person or designee is directly charged with reporting
**[all]{.underline}** oil spills that result from facility operations as
follows:

-   First, call **9-1-1** (or the local emergency agency) if there is an
    immediate emergency

-   Next, notify the appropriate persons within the NWS:

```{=html}
<!-- -->
```
-   **Mike Jacob, (301) 713-1838 Ext. 165, NWS Environmental Compliance
    Officer.**

-   **Olga Kebis, (301) 713-1838 Ext. 173, NWS Safety Officer**

-   **Terry Brisbin, (817) 978-2367 Ext. 139, NWS Southern Regional
    Environmental/Safety Coordinator**

-   **Sherilyn Villegas, (816) 426-3925 Ext. 263, NOAA Central Regional
    Compliance Officer**

    []{#__RefHeading___Toc502626702 .anchor}2. Federal Notifications

    The Federal Clean Water Act, as described in 40 CFR Part 110.6,
    requires notifying the U.S. Environmental Protection Agency (EPA)
    National Response Center (or the U.S. Coast Guard \[USCG\]) as soon
    as anyone has knowledge of any discharges of oil in quantities that
    "may be harmful." 40 CFR Part 110.3 defines "may be harmful" as a
    discharge for which one of the following applies:

```{=html}
<!-- -->
```
-   Violates applicable water quality standards

-   Causes a film or sheen upon or discoloration of the surface of the
    water or adjoining shorelines or cause a sludge or emulsion to be
    deposited beneath the surface of the water or upon adjoining
    shorelines

    If either of these criteria is met, contact the following:

-   The National Response Center (EPA and USCG): **(800) 424-8802.**

    Under the SPCC regulations, spill information listed in 40 CFR Part
    112.4(a) must be reported to the regional EPA office within 60 days
    if [either]{.underline} of the following occurs:

-   A discharge of more than 1,000 gallons of oil into or upon navigable
    waters or adjoining shorelines in a single event

-   Two spill events that cause visible sheens upon navigable waters or
    adjoining shorelines within any 12-month period

    Diesel fuel is not listed as a hazardous substance under the
    Comprehensive Environmental Response, Compensation, and Liability
    Act; therefore, no other notification to the EPA is required for
    discharges of diesel fuel other than those listed previously.

    []{#__RefHeading___Toc502626703 .anchor}3. State Notification

As required by the Arkansas Pollution Control and Ecology Commission any
spill of refined petroleum product (gasoline, diesel, oil, etc.) be
reported to the **Arkansas Department of Emergency Management** at
**(800) 322-4012.**

[]{#__RefHeading___Toc502626704 .anchor}4. Cleanup Contractor
Notification

An emergency response contractor should also be notified to assist with
the cleanup if necessary. NWS has identified the following contractors
that are available for an emergency response:

-   **{To be provided by facility}**

[]{#__RefHeading___Toc502626705 .anchor}PART IV - RECOMMENDED
IMPROVEMENTS

In accordance with 40 CFR Part 112.7, this section presents physical
upgrades or procedural changes not yet fully operational but called for
in the plan.

A.  []{#__RefHeading___Toc502626706 .anchor}PHYSICAL UPGRADES

```{=html}
<!-- -->
```
1.  []{#__RefHeading___Toc502626707 .anchor}Tanks

    An audible high-level alarm shall be installed set to sound at 90
    percent capacity (900 gallons) to help prevent overfills.

2.  []{#__RefHeading___Toc502626708 .anchor}Secondary Containment Bin
    Valve

The valve used to drain rainwater from the concrete secondary
containment bin shall be sealed in the closed position at all times
except to release clean rain water. Once the rain water is released, the
valve should be closed again.

[]{#__RefHeading___Toc502626709 .anchor}B. PROCEDURAL CHANGES

1.  []{#__RefHeading___Toc502626710 .anchor}Inspections and Preventative
    Maintenance

    The inspection checklists in Appendix B should be followed. This
    requirement is found in 40 CFR Part 112.7(e)(8). Visual inspections
    of the outside of the AST and the day tank should serve to signal a
    potential problem with their integrity.

2.  []{#__RefHeading___Toc502626711 .anchor}Training

The Environmental/Safety Focal Point and an alternate should be trained
in the intent of the applicable oil spill regulations and methods for
implementing the inspection and maintenance procedures outlined in the
previous section. Spill control and countermeasures should also be
included in the training. The alternate should be designated in case the
primary person is off site at the time of a spill. A recommended outline
for the training is found in Appendix C.

Training should be repeated once per year. All new personnel responsible
for implementing the SPCC plan should be properly trained before
beginning the new positions. A record of who was trained, when, and by
whom should be filed with the SPCC plan and kept for a period of 3
years. This requirement is found in 40 CFR Part 112.7(e)(10).
