Procedure for Unloading River Dock Barge of Ethanolinto Refinery Tank 80:

DateTimeInitials

1.______Verify that Tank 80 has sufficient room to hold the volume of product that will be unloaded from barge and remain below the safe fill height of the tank.

2.______Verify that all line-ups are correct for unloading the Barge.

3.______Sample Barge

3.1An Independent Inspector shall collect the following samples:

a)One (1) one-gallon marine vessel multiple compartment composite sample in an epoxy lined can from each barge according to General Sampling Procedure.This sample will be retained.

b)One (1) one-quart marine vessel multiple compartment composite sample in a plastic coated clear glass Boston round bottle from each barge according to General Sampling Procedure.

c)The one quart sample shall be inspected for visual appearance by the Inspector. (Clear & Bright and free of sediment and suspended matter).

Caution: If the sample does not meet the visual appearance standard the River Dock PIC should be notified immediately and the barge will not be unloaded until approved by the Scheduler and Tank Farm Superintendent or Shift Superintendent.

3.2All samples will be transported to the Lab for analysis.

3.3The #2 Pumper will check with the River Dock PIC to ensure the sampling has been completed and the barge is authorized to unload.

4.______Gauge Tank 80.

4.1If the gauging is to be done by an outside Inspector, the #2 Pumper will:

a) Pick-up the outside Inspector from the River Dock and take them to Tank 80.

b)Witness the Inspector getting the Tank gauge and Tank temperature to verify that the information obtained is accurate.

c)Return the Inspector to the River Dock and have the information recorded on the Barge Transfer Sheet.

4.2If the gauging is not to be done by an outside Inspector, the #2 Pumper will obtain a Tank gauge and Tank temperature and record on the Barge Transfer Sheet.

5.______Call the River Dock (ext. 8825) and advise them the Tank farm is ready to receive Ethanol from the Barge.

6.______Within 1 hour of the start of transfer or prior to shift change, a check gauge is performed to insure flow is proceeding properly into the correct tank.

Note: When any tank is receiving or transferring product beyond a shift change – a check gauge must be performed within 1 hour of the shift-change by the off-going Pumper and communicated to on-coming Pumper to alert the next shift of active tanks.

Tank Farm Actions after Transfer is Complete

Date TimeInitials

1.______Close out the transfer after the Barge unloading is complete

1.1If the opening Tank gauging was done by an outside Inspector, the #2 Pumper will:

a)Pick-up the outside Inspector from the River Dock and take them to the Destination Tank.

b)Witness the Inspector getting the closing Tank gauge, and Tank temperature to verify that the information obtained is accurate.

c)Return the Inspector to the River Dock and record the gauge and transfer information on the Barge Transfer Sheet.

1.2If the opening Tank gauge was not done by an outside Inspector the #2 Pumper will:

a)Obtain a Destination Tank closing gauge, and Tank temperature.

b)Give the closing Tank information to the River Dock Operator.

c)Record the transfer on the Barge Transfer Sheet. Include gauges, temperatures, and times.

2.______Open and close valves in system as necessary for desired or normal line-up.

PROCEDURE INFORMATION

PURPOSE

This procedure provides steps to follow to safely and efficiently unload a River Dock Barge of Ethanol into Refinery Tank 80

PREREQUISITES

The information on the shipment must have been communicated to the Refinery Tank Farm and the Refinery River Dock. The appropriate orders must have been written in the Refinery Tank Farm Log Book concerning the shipment.

RESPONSIBILITY

It is the responsibility of the Pumper Number 2 and the River Dock PIC to carry out this procedure in a safe and timely manner.

MATERIALSAND EQUIPMENT

No special materials and / or equipment are required to carry out this procedure.

SAFETY

Special or Unique Hazards:. The receiving tank, tank 80, must not be overfilled. If a Tank overflows it will create safety and environmental problems. It could result in a fire.

Engineering Controls:N / A

Administrative Controls:This procedure is a control to ensure that the Barge is unloaded safely and efficiently.

Personal Protective Equipment (PPE):Normal Tank Farm personal protective equipment must be worn at all times. This includes hard hats, steel-toed footwear, fire retardant clothing and safety glasses. Additional protective equipment may be required per permit requirements.

SAFETY SYSTEMS

Shutdowns: N/A

Other Safety:The Refinery Tank Farm, the River Dock and West Memphis Terminal Control Rooms are equipped with computer interface terminals to allow monitoring of the shipping process.

QUALITY AND INVENTORY

Inventory:The Refinery Ethanol Destination Tank must have sufficient room to hold the volume of product that will be unloaded.

Quality:Product being unloaded should meet the quality specifications of the product that was previously given to the refinery.

OPERATING LIMITS:

Description / Limits / Consequences of Deviation / Corrective and Avoidance Steps
Tank Maximum Level / Tk 80: 34 Ft. / If a Tank is overfilled and Ethanol is released to the atmosphere it will create a safety and environmental problem as well as loss of product. Overflowing a Tank can result in fires and explosions. / Prior to unloading the Barge check the Destination Tank gauge to ensure there is sufficient room in the Tank to hold the volume of product that will be unloaded.
Minimum Unloading Rate / Dependent on the Barge Unloading Pump. / Product may overheat in the pump and flash with resulting damage to pump. Could cause safety and environmental problems. / The flow rate needs to be maintained above the minimum pump design rate to avoid the product from overheating in the pump and flashing. If problems are encountered due to low flow rate, the unloading rate should be increased or the unloading shutdown.

CHEMICAL SAFETY:

General information is provided here. Additional information is available from the MSDS sheets for individual chemicals.
