A.  []{#__RefHeading___Toc503166849 .anchor}SITE DESCRIPTION AND
    OPERATIONS

    1.  []{#__RefHeading___Toc503166850 .anchor}Facility Location,
        Layout, and Operations

The facility is located in the Tualatin Mountains of Washington County,
Oregon, approximately 20 miles northwest of the Portland International
Airport (Figure 1). The nearest town is Scappoose, Oregon, approximately
4 miles northeast of the site. Figure 2 shows the layout of the
facility, including location of the 1,000-gallon aboveground storage
tank (AST) connected to two 250-gallon generator day tanks. The fuel in
the tanks is used to power an 80-kilowatt emergency backup power
(electric) generator. The surrounding area is undeveloped and wooded.

The estimated fuel usage is approximately 600 gallons per year. This
estimate is based on an automatic test of the generator once per week
for 45 minutes. Fuel consumption would increase based on the frequency
and duration of any power outages.

2.  []{#__RefHeading___Toc503166851 .anchor}Facility Storage

The main storage tank is a 1,000-gallon, ConVault^^ AST, rectangular in
shape. The primary steel tank is steel wrapped in styrofoam insulation
and an impervious barrier of 30-mil high-density polyethylene (HDPE)
membrane. This composite is then encased in a 6-inch thick concrete
vault. The tank has a primary and an emergency vent.

A supply line from the storage tank is encased in a polyvinyl chloride
pipe that exits the ConVault^^from its top and runs overhead into the
generator building. The fuel is transported to the west day tank by a
pump in the generator building.

The two, 250-gallon single-walled day tanks are rectangular in shape and
located inside the generator building. They are connected to each other
in two places via a 2-inch rubber line. Each tank has a vent pipe out
the top that merges together into one pipe that is vented out the side
of the generator building. The west tank is connected to the pump that
brings fuel from the storage tank and has a fuel supply and return lines
connect to the generator. The west tank also has a low-level sensor that
is remotely monitored at the Portland Weather Forecast Office and River
Forecast Center (WFO/WFC) located approximately 25 miles away.

Table 1 summarizes the pertinent information on the tanks at the
facility.

3.  []{#__RefHeading___Toc503166852 .anchor}Drainage Pathway and
    Distance to Navigable Waters

Any spilled fuel oil from the facility, regardless of initial direction,
would travel south down the relatively steep gravel access road toward
Dixie Mountain Road. There are no storm drain inlets along the access
road or Dixie Road, only open ditches. The site is located in the
headwaters of McKay Creek, a tributary to Dairy Creek that flows into
the Tualatin River, a tributary of the Willamette River.

4.  []{#__RefHeading___Toc503166853 .anchor}Spill History

[Reportable Spill events from March 1995 to present (date on cover of
this plan):]{.underline}

None.

5.  []{#__RefHeading___Toc503166854 .anchor}Spill Potential, Volumes,
    and Rates

The most probable causes for spills from the storage tank are from
overfilling or a ruptured hose during fueling. For this tank, spills
caused by failure of the fuel supply line, loss of structural integrity,
vehicle collisions, or earthquakes are low probability events. For the
day tanks, the probable causes of spills 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___Toc503166855 .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___Toc503166856 .anchor}SPILL PREVENTION

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

1.  []{#__RefHeading___Toc503166857 .anchor}Bulk Storage Tanks and
    Facility Transfer Operations

[Storage Tank:]{.underline} The tank construction shall be compatible
with the number 2 diesel fuel held by the tank. The tank shall have
secondary containment around the primary tank shell. A float-type level
gauge shall indicate the fuel level (from empty to full).

An automatic shut-off valve on the fill spout shall be set to close at
90 percent of the tanks capacity (900-gallons). The tank also shall have
an audible high-level alarm set at 85 percent of capacity (850‑gallons)
and interstitial monitoring device between the primary and secondary
tanks that is connected to the audible alarm system. A
10-gallon-capacity round spill container shall surround the fill spout.

> [Day Tanks:]{.underline} The tank construction shall be compatible
> with the number 2 diesel fuel held by the tank. The generator building
> is 9 ½ feet wide and 15 ½ feet long and has a 9-inch-high lip on the
> door. Excluding displacement from the equipment, there is
> approximately 825 gallons of capacity within the sealed concrete floor
> of the building for secondary containment.
>
> [Piping:]{.underline} An antisiphoning valve shall be located between
> the main storage tank and the pump to prevent unwanted fuel from being
> siphoned from the storage tank. The overhead piping shall be contained
> within another pipe and protected from damage.

2.  []{#__RefHeading___Toc503166858 .anchor}Tank 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 tank truck into the storage
> tank 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 [prior]{.underline} to fuel
> unloading:

-   Ensure that the audible high-level alarm system and the automatic
    shutoff valve are function properly.

-   A NWS representative should determine the available capacity
    (ullage) of the tank by converting the reading on the fuel gauge 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 tank truck wheels.

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

-   The NWS representative and the delivery driver ensure the fill
    nozzle is place in the appropriate tank appurtenance. In this case,
    the fill nozzle is placed in the fill pipe connected to the
    10-gallon-capacity round spill container.

> Both the NWS representative and the delivery driver shall remain with
> the vehicle at all times during unloading. Gauges on the tank and the
> truck shall be continuously monitored to ensure the ullage is not
> exceeded. If the audible high-level alarm sounds, the unloading of
> fuel shall be stopped as soon as possible.
>
> After fuel unloading is completed:

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

-   Drain the fill hose and then ensure that all drain valves are closed
    (if applicable) prior to removal of the hose from the tank

-   Pour any fuel in the drip pans, tank truck containment pool, or
    spill container on the fill pipe into the tank (if it has the
    capacity) or disposed of appropriately.

-   Inspect the tank truck prior to 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.

    2.  []{#__RefHeading___Toc503166859 .anchor}Inspections And Records

> [Inspection and Maintenance of Tanks]{.underline}: The storage tank
> 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
> 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.

3.  []{#__RefHeading___Toc503166860 .anchor}Site Security

> The tank 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 and
> be the status of the door lock shall be remotely monitored from the
> Portland WFO/RFC. Signage around the tank 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 tank. A fire
> extinguisher shall be located in the adjacent generator building. The
> tank is not located in the direct line of parking lot traffic;
> therefore no guard posts are required.

4.  []{#__RefHeading___Toc503166861 .anchor}Training

> The Environmental/Safety Focal Point (person responsible for spill
> prevention at the facility) and an alternate shall be trained in the
> intent of applicable oil spill regulations and how to implement
> the inspection and maintenance procedures outlined in paragraph 3,
> above. 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,

> of 3 years.

B.  []{#__RefHeading___Toc503166862 .anchor}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___Toc503166863 .anchor}Secondary Containment
    Designs, Construction Material, and Volume

> The secondary containment tank on the storage tank and the sealed
> floor in the generator building beneath the day tanks shall be sized
> to contain 110 percent of the tank volumes. Both of these secondary
> containment features shall be enclosed to prevent precipitation from
> entering. An interstitial monitoring system that can detect fuel of 1
> inch or more in the secondary shell of the storage tank shall be
> included.

2.  []{#__RefHeading___Toc503166864 .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 building 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___Toc503166865 .anchor}PART III - SPILL COUNTERMEASURES
AND REPORTING

The primary emphasis of this SPCC plan is on prevention. The spill
countermeasures presented do [not]{.underline} constitute a contingency
plan detailed in Title 40 CFR Part 109, nor is one required. Such a plan
is only required under Title 40 CFR 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 Title 40 CFR Part
112.20 since it does [not:]{.underline}

-   Transfer oil over water from vessels and have a total oil storage
    capacity of greater than or equal to 42,000 gallons, or

-   Have a total storage capacity over 1 million gallons.

Should a spill occur the following measures would be implemented:

A.  []{#__RefHeading___Toc503166866 .anchor}SPILL COUNTERMEASURES

> This section presents countermeasures to contain, cleanup, 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 drainage ditches 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 next section for assistance in control and cleanup.

B.  []{#__RefHeading___Toc503166867 .anchor}SPILL REPORTING

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

A spill report form that requests the information to be reported to all
agencies in written form (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 NOAA Western Regional Compliance Officer (see
next section).

1.  []{#__RefHeading___Toc503166868 .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:

> Worker security and safety needs improvement around the storage tank.
> The tank shall have a "NO SMOKING" sign and a "CAUTION -- COMBUSTIBLE
> LIQUID" sign clearly posted. The tank should have a sign that reads
> "DIESEL FUEL." These signs are required by the state Fire Marshall.

3.  []{#__RefHeading___Toc503166876 .anchor}Spill Kits

> NWS shall purchase adequately sized spill kits and store them near the
> tanks. The current kit in the generator building is for spills up to 4
> gallons. NWS shall purchase a kit capable of handling at least
> 40-gallons. The kit should include oil absorbent socks and mats in a
> polyethylene container that doubles as a disposal container. In
> addition, it is highly recommend that the facility have urethane spill
> barriers available. These barriers can direct or contain a relatively
> small spill and prevent it from reaching navigable waters. This
> requirement is found in Title 40 CFR Section 112.7(c)(1)(iv) and
> (vii).

```
1.  []{#__RefHeading___Toc503166878 .anchor}Tank Truck Unloading
    Procedure

> The current tank truck unloading area does not drain into a catchment
> basin or a treatment facility designed to handle spills. However,
> since unloading of fuel occurs only approximately once per year on
> average, the following procedural improvement should be implemented.
> Containment booms and spill barriers from the spill kit described in
> Part IV, Section A.3. of this plan shall be made easily accessible
> during tank truck unloading. The containment booms and spill barriers
> combined with constant monitoring of the fuel unloading process by NWS
> personnel will meet the substantive requirements of Title 40 CFR
> Section 112.7(e)(4).

2.  []{#__RefHeading___Toc503166879 .anchor}Inspections and Preventative
    Maintenance

> The inspection checklists found in Appendix B should be followed. This
> requirement is found in Title 40 CFR Section 112.7(e)(8). The
> interstitial monitoring device in the storage tank is designed to
> monitor the integrity of the primary tank. Visual inspections of the
> outside of the secondary wall of the storage tank and the primary wall
> of the day tanks should serve to signal a potential problem with their
> integrity. However, if a problem is suspected with any tank, tightness
> testing should be initiated soon after discovery.

3.  []{#__RefHeading___Toc503166880 .anchor}Training

> The Environmental/Safety Focal Point (person responsible for spill
> prevention at the facility) and an alternate should be trained in the
> intent of the applicable oil spill regulations and how to implement
> 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 position. A record of who was trained, when,
> and by whom, should be filed with this SPCC plan and kept for a period
> of 3 years. This requirement is found in Title 40 CFR 112.7(e)(10).

                         2               Determine the available capacity (ullage) of     
                                         tank by converting the reading on the fuel gauge 
                                         to gallons (See Appendix A, Page A-1). This      
                                         ullage should then be marked in the fueling log  
                                         and communicated to the tank truck unloading

                         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   
                                         tank and before unloading.                       

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

  **During unloading:**                                                                   

                                    7    Ensure that the NWS representative and the tank  
                                         truck operator remain with the vehicle at all    
                                         times 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    
                                         possible.
