Murray State University is required under the Clean Water Act to prepare a Spill Prevention Control and Countermeasures Plan. Electrical substations that must comply are located in two areas of the main campus. This plan addresses spill prevention control and countermeasures in the event of potential releases from these large oil-filled electrical transformers. The requirements of the Act also mandates a control and countermeasures plan for the ethanol fueling station located on the main campus.

 

 

Location of substations and fueling station are as follows:

  • Facilities Management Compound
  • Central Heating and Cooling Plant
  • Transportation Ethanol Fueling Station, Facilities Management Compound
  • Transportation Used Oil Storage Tank, Facilities Management Compound

 Spill Prevention and Security

 Prevention:

  • Facilities Management personnel shall maintain electrical substation equipment in good working order, including periodic painting, thus providing corrosion control.
  • Facilities Management personnel shall wipe off seepage during maintenance operations.
  • Facilities Management personnel shall control leaks and seepage through repair and maintenance.
  • The fueling station shall be regularly inspected by the motor pool and maintained by Facilities Management.

 Security:

  • All substations are enclosed with gated entry 8’ high cyclone, barbed-wire perimeter fences. Management personnel shall lock gates when equipment servicing is completed and conduct periodic checks to ensure that security has not been compromised.

 

Detection and Notification

Detection:

Large leaks are rare in this type of equipment. It should be noted however, that substantial leaking would cause the uncovering of the transformer core and result in catastrophic transformer failure. The failure of any one of the large transformer reservoirs would result in an approximate release of 1,500 gallons of oil. Electric Shop or Heating and Cooling personnel would most likely discover seepage or a spill.

 

Seeping oil and Small Incidental Spill:

  • Facilities Management personnel shall wipe up seeping non-PCB oil and/or small leaks, from transformers at the time of the discovery and/or when the equipment is de-energized.
  • Seepage is apt to occur around insulators or fittings in the transformer cases. Facilities Management personnel shall carefully observe seepage.

Notification of Contacts:

Facilities Management personnel should report the spill immediately to: Mr. Jeff Steen, Assistant Director of Emergency Management Office of Environmental Safety and Health, Department for Facilities Management or Ms. Gay Wellinghurst, Laboratory Safety Officer for Environmental Safety and Health.

The Kentucky Cabinet for Environmental Protection shall be notified within one hour of determining that more than 75 gallons of oil has been released. Mr. Steen or Ms. Wellinghurst shall contact the Kentucky Department of Natural Resources and Environmental Protection. Should both contacts be unavailable, the first available Facilities Management staff member should be contacted and that individual should call the Environmental Protection Agency.

I.    FACILITIES MANAGEMENT COMPOUND SUBSTATION-CONTROL PLANS

Quantity of Oil – 3,000 Gallons in two transformers

A large spill from this substation would likely flow N or S initially and then W toward the Hazardous Materials storage building located approximately 40 yards NW of the substation.

  • V-Dike(s) may be constructed to prevent the spread of the oil, unless the spill has reached the drainage ditch located due north of the substation. This ditch drains from E to W into a larger underground storm water tunnel.
  • Dams to block impending spills from entering the storm water tunnel should be constructed by using shovels, and/or a backhoe.
  • A siphon dam may be built using PVC piping (see page 10), if the ditch contains flowing water at the time of the spill. This will allow water to continue flowing toward the storm tunnel while blocking the transformer oil (not miscible, specific gravity >1.0), from entry.
  • Deploying skimming booms if sheen is visible on water that has passed through the dam. Skimming booms are located in the hazardous materials storage building and on the ESH box truck or in the Hazardous Waste Storage Building.
  • Sand, which can serve as additional V-dike material, is often available at the S end of the Facilities Management Grounds Department Building.
  • Place plywood over the culverts under the access road to the hazardous materials storage building, and/or the entrance to the storm ditch as an alternative to the above methods.
  • Call suction trucks to pick up and dispose of the oil.

II.     CENTRAL HEATING AND COOLING PLANT SUBSTATION – CONTROL PLANS

Quantity of Oil- 10,390 Gallons

 This substation is located N of the Murray State University’s Central Heating and Cooling Plant. A storm water tunnel is located underneath the substation yard. The substation has 2 grated drain and 3 manhole covered entrances into this tunnel. The 2 largest transformers located here contain 5,390 gallons of oil each. The total amount of oil for the remaining 12 transformers at the Central Heating and Cooling Plant equals 5,000 gallons.

 

  • Sewer blockers, located in the substation switchgear building, or six-mil plastic sheeting, stored in the ESH service truck, should be used to block a spill from entering the storm water tunnel.
  • Create a depression by digging the ground area immediately surrounding drain entrances in an effort to inhibit oil spillage into the tunnel.
  • Skimming booms, stored in the hazardous materials storage building and the ESH service truck, should be deployed if oil has entered the storm water tunnel. If water in the tunnel is low, skimming booms should be deployed at the Central Heating and Cooling Plant Substation and the Industry and Technology Building. If water is moving through the tunnel, skimming booms should be deployed at its exit, located at the N side of Highway 121 near University Church of Christ.
  • The MSU Confined Space Entry Program shall be in effect whenever entry is made into the storm water tunnel.

 

III.     TRANSPORTATION ETHANOL FUELING STATION- CONTROL PLANS

 

Quantity of Ethanol- 3,000 Gallons

The ethanol fueling station is located at the transportation department within the Facilities Management compound. It is approximately 80’ E of the transportation garage and approximately 95’ N of the Hazardous Materials storage building. The above ground tank is a 3,000 gallon, double steel-wall package type with one fueling pump and hose. The system uses an electrically operated pump. An automatic shut-off on the pump nozzle and an emergency shut-off switch near the nozzle deactivates the power to the pump. Crash posts erected around the tank provide protection.

 

  • Large ethanol releases of 25 gallons or more may be addressed by calling in a Hazardous Material contractor, (see resources). In the event of a spill, the product would flow S toward the storm water drainage ditch due S form the fueling station.
  • It should be noted that ethanol is a Class I B flammable liquid with a flash point of 55 F. A catastrophic release would be unlikely.
  • A small spill of 5 gallons or less should be addressed by using he absorbent pads located in close proximity to the fueling pump.
  • Used absorbents should be placed in an appropriate container for disposal.
  • A V- Dike die S of a spill may ne constructed to prevent or reduce the flow of ethanol into the drainage ditch. A portable spill dike is located at the fueling station.
  • Sand, which can serve as additional V-Dike material, is often available at the Facilities Management Grounds Department Building approximately 50 yards W of the ethanol tank.
  • Vapor suppression, whenever necessary, can be achieved by the application of foam available from the Murray Fire Department.

 Additional containment may be achieved by:

  • The placement of sandbags at the storm drain points of entry to culverts. Sandbags located in the mechanical room of the hazardous material building can be used to block ethanol from flowing into the storm water tunnel located underneath the Facilities Management compound.

 If the ethanol has already entered the storm water tunnel:

  • Extreme care should be taken to eliminate ignition sources around the storm water/sewer tunnel. Areas N of the ethanol fuel tank to Hwy 121, and S of the tank to Chestnut Street should be considered. Additional ignition sources isolation may be necessary pending evaluation.
  • Ethanol is water-soluble, so flushing the storm water tunnel with water should greatly reduce the potential for fire or explosion.

 

IV.     TRANSPORTATION USED OIL STORAGE – CONTROL PLANS

 

Quantity of Used Oil – 350 Gallons

The oil reserve tank is located at the Southwest corner of the transportation garage within the Facilities Management compound. It is approximately 200’ northwest of the hazardous materials storage building. The above ground tank is a 350 gallon composite plastic.

 

  • Large oil releases of 25 gallons or more may be addressed by calling in a Hazardous Material contractor, (see resources). In the event of a spill, the product would flow S toward the storm water drainage ditch due S form the fueling station.
  • A small spill of 5 gallons or less should be addressed by using he absorbent pads located in close proximity to the fueling pump.
  • Used absorbents should be paced in an appropriate container for disposal.
  • A V- Dike die S of a spill may ne constructed to prevent or reduce the flow of ethanol into the drainage ditch. A portable spill dike is located at the fueling station.
  • Sand, which can serve as additional V-Dike material, is often available at the Facilities Management Grounds Department Building approximately 15 yards W of the oil tank.
