[]{#__RefHeading___Toc502625690 .anchor}B. SITE DESCRIPTION AND
OPERATIONS

This section describes the site and its operations.

[]{#__RefHeading___Toc502625691 .anchor}1. Facility Location, Layout,
and Operations

The facility is located approximately 1 mile southeast of the
intersection of Interstate Highway 820 and Interstate Highway 35W in
Fort Worth, Tarrant County, Texas (Figure 1). Figure 2 shows the layout
of the facility, including the location of a 2,034‑gallon aboveground
storage tank (AST). The fuel in the AST is pumped to a 25‑gallon day
tank connected to an emergency backup power (electric) generator. The
day tank and generator are located in the enclosed generator building.

The estimated fuel usage is approximately 40 gallons per month. This
estimate is based on the current practice of running the generator once
per week for approximately 2 hours. Fuel consumption would increase
based on the frequency and duration of any power outages.

[]{#__RefHeading___Toc502625692 .anchor}2. Facility Storage

The double-walled, welded steel plate AST is rectangular in shape and
horizontally situated. The primary tank is completely contained within a
secondary steel tank. The 6‑inch interstitial space between the primary
and secondary tanks is filled with concrete. A leak monitor is installed
between the inner tank and a surrounding polyethylene liner.
Additionally, a concrete dike with a capacity of approximately 450
gallons surrounds the AST. The dike is provided with a gate valve to
drain rainwater. The fill spout on the AST is equipped with a
rectangular 7‑gallon spill container. The AST is equipped with a vent.

The AST is connected to an Auto Stick Series 950 Model 7021 monitor. The
automatic unit continuously monitors the fuel level in the AST and
provides low- and high-level alarms, water level alarm, and leak
detection. The unit is currently set for low alarm at 150 gallons, high
alarm at 2,010 gallons, water alarm at 3 inches, and leak detection at
0.20 gallon per hour. The tank is located within a concrete containment
dike with a capacity of approximately 450 gallons. This dike, 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, a siphon breaker, and a 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.
Table 1 summarizes the pertinent information on the tanks at the
facility.

[]{#__RefHeading___Toc502625693 .anchor}3. Drainage Pathway and Distance
to Navigable Waters

Any fuel oil spilled from the AST or from the generator day tank would
flow northeast across the concrete to the edge of the fenced area, east
across the grass area, through drainage pipes under the concrete
sidewalk, then east across the grass area to one of two storm water
inlets that convey storm water under the existing concrete slabs (Figure
2). Spills entering the north storm water inlet would discharge to the
grassy area east of the slab and then flow south toward Northern Cross
Boulevard, where they would enter the storm water system east of the
site. Spills entering the south storm water inlet would discharge
upgradient from a drop inlet to the storm sewer system. Any spills
reaching the storm water system would be conveyed east to a
concrete-lined drainage channel approximately 1,000 feet east of the
facility. This ditch discharges to Little Fossil Creek, approximately
7,000 feet south of the facility. Little Fossil Creek combines with Big
Fossil Creek, a tributary of the West Fork of the Trinity River.

[]{#__RefHeading___Toc502625694 .anchor}4. Spill History

[Reportable spill events from 1993 to the date on the cover of this
plan:]{.underline}

None.

[]{#__RefHeading___Toc502625695 .anchor}5. Spill Potential, Volumes, and
Rates

The most probable causes of spills from the AST are from either
overfilling or a ruptured hose during fuel unloading. The pump that
conveys fuel from the AST to the day tank is located with the generator
building. The line between the AST and the day tank operates under
suction, which would minimize leaks in case the line failed. For the
AST, spills caused by loss of structural integrity or vehicle collisions
are low-probability events. The most probable cause of spills from the
day tank is from a failure of the pump to shut down.

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

[]{#__RefHeading___Toc502625696 .anchor}PART II - DESIGN COMPONENTS AND
OPERATIONAL PROCEDURES\
FOR SPILL PREVENTION AND CONTROL

This section discusses spill prevention and control measures that have
been implemented at the facility.

[]{#__RefHeading___Toc502625697 .anchor}A. SPILL PREVENTION

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

1.  []{#__RefHeading___Toc502625698 .anchor}Bulk Storage Tanks and
    Facility Transfer Operations

[AST:]{.underline} The AST is constructed of steel, which is compatible
with diesel fuel held by the AST. The AST is double-walled so that any
failure of the primary tank will be contained within the secondary tank.
Additionally, the AST is located within a concrete secondary containment
dike with an approximate capacity of 450 gallons. The current practice
is to refill the AST when the level drops approximately 500 gallons, so
most overspills encountered during refueling would be contained within
this dike. The concrete containment dike is provided with a gate valve
to drain accumulated rain water. A 7‑gallon spill container surrounds
the tank fill spout. The AST is currently connected to an Auto Stik
continuous monitor. An interstitial monitor between the primary and
secondary tanks is also connected to this system. The AST is not
currently equipped with an external gauge that would allow the fueler to
determine the level in the AST without entering the building.

[Day Tank:]{.underline} This tank is an enclosed steel tank equipped
with a liquid level gauge to indicate the amount of fuel in the tank
(empty to full) and a float switch connected to the transfer pump.

[Piping:]{.underline} An antisiphoning valve is located on the
aboveground piping between the AST and the pump to prevent unwanted fuel
from being siphoned from the AST.

[]{#__RefHeading___Toc502625699 .anchor}2. 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 will determine the available capacity (ullage)
    of the AST. This ullage will be 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 place in the appropriate AST appurtenance. In this case,
    the fill nozzle shall be connected to the cam-lock fitting on the
    4-inch pipe within the spill container.

Both the NWS representative and the delivery driver shall remain with
the vehicle at all times during unloading. Gauges on the AST and 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
    spill container on the fill pipe 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 tank.

-   Remove the blocks from truck wheels.

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

[]{#__RefHeading___Toc502625700 .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. On a monthly basis the operation of the day tank
float switch shall be checked. 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___Toc502625701 .anchor}4. Site Security

The AST has adequate lighting to detect spills at night and a security
fence with a locked gate to prevent tank damage or spills caused by
vandalism. Additionally, a security camera is mounted in the storage
area. 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 number 2, and that smoking is not
permitted near the AST. The AST is not located in a traffic area, so no
guard posts are required.

[]{#__RefHeading___Toc502625702 .anchor}5. Training

The Environmental/Safety Focal Point and at least one alternate shall be
trained in the intent of applicable oil spill regulations and how to
implement 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___Toc502625703 .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___Toc502625704 .anchor}Secondary Containment
    Designs, Construction Material, and Volume

The AST is constructed of steel, which is compatible with diesel fuel
held by the AST. The AST is double walled so that any failure of the
primary tank will be contained within the secondary tank. Additionally,
the AST is located within a concrete secondary containment dike with an
approximate capacity of 450 gallons. The concrete containment dike is
provided with a gate valve to drain accumulated rain water. A 7‑gallon
spill container surrounds the tank fill spout. The tank is currently
connected to an Auto Stik continuous tank monitor. An interstitial
monitor between the primary and secondary tanks is also connected to
this system.

[]{#__RefHeading___Toc502625705 .anchor}2. Spill Kits Type and Location

The facility has a spill kit designed to absorb diesel fuel and to
prevent spills from reaching navigable waters. The kit is stored in the
fenced area behind the building near the AST. The kit includes oil
absorbent socks and mats in a polyethylene container that doubles as a
disposal container. In addition, the kit contains a polyurethane pad
that can be used to block small drain inlets.

[]{#__RefHeading___Toc502625706 .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___Toc502625707 .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 away from the storm drainage system 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___Toc502625708 .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 Southern Region Facility
Engineer and the National Oceanic and Atmospheric Administration (NOAA)
Mountain Administrative Support Center Environmental Engineer (see
following section).

1.  []{#__RefHeading___Toc502625709 .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

```{=html}
<!-- -->
```
-   Next, notify the appropriate persons within the NWS:

    Observation and Facilities.**

-   **Mark George, (303) 497-3064, NOAA Mountain Region Compliance
    Officer**

1.  []{#__RefHeading___Toc502625710 .anchor} 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 110.3 defines "may be harmful" as a discharge for which one of
the following applies:

-   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___Toc502625711 .anchor}3. State Notification

As required by the Section 26.039 of the Texas Water Code and Texas
Administrative Code Sections 327.1 through 327.5, any spill of refined
petroleum product (gasoline, diesel, oil, etc.) of 25 gallons or more on
onto land any spill or discharge directly to water in the state must be
reported to the **Texas Natural Resource Conservation Commission
(TNRCC)** at one of the following**:**

-   The State Emergency Response Center at 1-800-832-8224

-   During business hours (8:00 a.m. to 5:00 p.m., Monday through
    Friday), contact the TNRCC Region 4 Regional Office at 817-469-6750

-   At the 24-hour spill reporting number at 1-512-239-2507 or
    1-512-463-7727

[]{#__RefHeading___Toc502625712 .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___Toc502625713 .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___Toc502625714 .anchor}PHYSICAL UPGRADES

```{=html}
<!-- -->
```
1.  []{#__RefHeading___Toc502625715 .anchor}Tanks

The AST shall be provided with a gauge to indicate the level of fuel in
the AST that is visible from outside where refueling operations will
occur. This will assist in determining the ullage before fuel unloading.
Also, the high-level alarm shall be set to sound at 90 percent capacity
(approximately 1,831 gallons) to help prevent overfills.

1.  []{#__RefHeading___Toc502625716 .anchor}Secondary Containment Drain
    Valve Seal

The valve used to drain rainwater from the concrete secondary
containment 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___Toc502625717 .anchor}B. PROCEDURAL CHANGES

[]{#__RefHeading___Toc502625718 .anchor}1. 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). The interstitial
monitoring device in the AST is designed to monitor the integrity of the
primary tank. Visual inspections of the outside of the secondary wall of
the AST and the primary wall of the day tank should serve to signal a
potential problem with their integrity. If a problem is suspected with
any tank, however, tightness testing should be initiated soon after
discovery.

The Environmental/Safety Focal Point and at least one 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 countermeasure
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).

[]{#__RefHeading___Toc502625720 .anchor}3. Draining Inspection and
Record Keeping

Before rainwater is drained from the diked area, the water in the diked
area will be inspected. If the water contains visible fuel or a sheen,
the water will not be discharged but will be disposed of properly. If no
fuel or sheen is observed, the seal on the gate valve will be removed,
and the valve will be opened to allow the water to drain. Once the water
has drained, the valve will be reclosed and resealed. This inspection
and drainage will be recorded on the form in Appendix F and maintained
in the SPCC plan for 3 years.

                         2                Determine the available capacity (ullage) of   
                                          the aboveground storage tank (AST) by          
                                          converting the reading on the fuel gauge to

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

                         4                Block the wheels of the tank truck.            

                         5                Place drip pans under all pump hose fittings   
                                          (if applicable) after the hose is hooked up to 
                                          the AST and before unloading.                  

                         6                Ensure the fill nozzle is placed in the        
                                          appropriate AST appurtenance. In this case,    
                                          the fill nozzle is placed in the fill pipe     
                                          connected to the round spill container.        

  **During unloading:**

                                    8     Monitor the gauges on the AST and the truck    
                                          continuously to ensure the ullage is not       
                                          exceeded. If the audible high-level alarm      
                                          sounds, stop the unloading of fuel as soon as
