**B. SITE DESCRIPTION AND OPERATIONS**

The San Angelo Weather Station is located in San Angelo, Texas. The
mission of the Weather Station is to forecast weather and issue severe
weather warnings. The location of the facility is shown on Figure 1.
Figure 2 shows the layout of the facility, including the location of a
500-gallon aboveground storage tank (AST), a 65-gallon day tank, and two
250-gallon Radar Data Acquisition (RDA) tanks.

The tanks are used to supply fuel to two emergency generators on the
site. The 500-gallon AST and 65-gallon day tank store fuel that is used
to power a 175-kilowatt (kW) Weather Station office's emergency
generator. The day tank and 175-kW generator are inside the generator
room immediately northeast of the office and are not exposed to
precipitation. The 500-gallon AST is located immediately outside and
northeast of the generator room. The two 250-gallon RDA tanks store fuel
that is used to power the facility's RDA emergency generator, which
supplies backup electricity to the RDA tower and equipment located
approximately 700 feet northeast of the Weather Station office. The RDA
tanks and RDA generator are located in the RDA generator room.

The 500-gallon AST is a shop-built, welded, steel plate tank enclosed
inside a steel outer shell that provides sufficiently impervious
containment and protects the AST and the containment area from
precipitation. A float-type level gauge indicates the fuel level (from
empty to full) in the AST. A 5-gallon rectangular spill container
surrounds the fill spout. The AST is equipped with an audible high-level
alarm and an automatic shut-off valve on the cam-lock fitting fill
spout. An interstitial monitoring device between the primary steel tank
and steel outer shell (secondary containment) is connected to the
audible alarm system. The AST has a 2-inch-diameter vent and a
6-inch-diameter emergency vent. The AST is connected to a pump on top of
the 65-gallon day tank via a 1-inch diameter steel pipe. The pump moves
fuel from the AST into the day tank. The 1-inch diameter steel pipe is
encased by a 4-inch diameter poly-vinyl chloride (PVC) pipe from the top
of the AST to the exterior wall of the generator room.

The 65-gallon day tank is a single-walled rectangular steel tank located
within the generator room. The day tank is equipped with a liquid level
gauge to indicate the amount of fuel in the tank (from empty to full),
and is also equipped with an overflow basin. The tank is connected to
the generator by flexible rubber supply and return lines.

The two 250-gallon RDA tanks are shop-built rectangular, single-walled,
welded steel plates located inside the RDA generator building that is
designed to provide sufficient containment of potential spills. Fuel for
the RDA generator is fed directly from the RDA tanks via rubber supply
lines.

The estimated fuel usage is approximately 30 gallons per month. This
estimate is based on an automatic test of the generators once per week
for 1 hour. Fuel consumption may increase depending on the frequency and
duration of any power outages.

Fuel spilled from the area of the 500-gallon AST could travel to the
grassy areas surrounding the concrete pad on which the AST is located.
Fuel spilled from the RDA area could travel to the gravel and grassy
areas surrounding the RDA generator building. Spills from either tank
locations may eventually travel to the drainage ditch paralleling
Knickerbocker Road.

The facility should maintain spill kits designed to absorb diesel fuel
and which can prevent discharged oil from reaching nearby water bodies.
Two spill kits that include oil absorbent socks, pads, and booms
contained in a 85-gallon polyethylene containers that can be used as a
disposal container are located between the 500-gallon AST and the
generator room.

**PART II - OPERATIONAL PROCEDURES FOR SPILL PREVENTION AND CONTROL**

**1. Fuel Unloading**

The fueling tank trucks are staged near the tanks when fueling in the
adjacent paved areas. The fueling trucks typically fill the tanks at a
rate of about 40 gallons per minute.

a.  Appendix A includes a Tank Ullage and Fueling Log (Appendix A-1)
    that should be used when fuel is delivered; and

b.  Fuel Unloading Procedure Checklist (Appendix A-2) that includes a
    list of procedures that should be implemented when fuel is
    delivered.

2.  **Inspections and Records**

> [Inspection and Maintenance of Tanks]{.underline}: All of the tanks
> should be inspected weekly for any oil outside the tanks, especially
> at seams (including the underside). The outside of any exposed piping
> should be inspected weekly, especially at the joints such as gasket
> fittings. Monthly and annual inspections should follow the checklists
> presented in Appendix B.
>
> [Record Keeping]{.underline}: The designated person responsible for
> spill prevention or alternate representative is responsible for
> completing the ullage logs and documenting fuel unloading procedures.
> These records, as well as records of all inspections, should be
> maintained for at least 5 years from the time of inspection.

**PART III - SPILL COUNTERMEASURES AND REPORTING**

A.  **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 countermeasures will be undertaken until
conditions are safe for workers. The **[SWIMS]{.underline}** procedure
should be implemented as countermeasures as follows:

**S** - Stop the leak and eliminate ignition sources.

> a\. Attempt to seal or some how stop leak if it can be done safely.
>
> b\. Attempt to divert flow away from the drainage ditch with a spill
> barrier or the contents of spill kit. The spill kit is located in the
> generator building.
>
> c\. Eliminate all ignition sources in the immediate area.

**W** - Warn others.

> a\. Yell out "SPILL." Inform the person in-charge at your facility.
>
> b\. Account for all personnel and ensure their safety.
>
> c\. Notify contacts and emergency response contractor as described in
> the following section for assistance in control and cleanup.

**I** - Isolate the area.

a\. Rope off the area.

**M** - Minimize your exposure. Stay upwind.

**S** - Stand by to assist the emergency response contractor, if
necessary.

**B. SPILL REPORTING**

**1. General Notification Procedures for All Spills**

> Within 24 hours, the responsible person or designee (DRO on this plan
> title page) is directly charged with reporting [all]{.underline} oil
> spills that result from facility operations as follows
