Wayne Sowards of Trapper Mining Inc. reported <br />to you a spill of diesel fuel. This spill occurred on the Trapper Mine and <br />resulted in the loss of approximately 6500 gallons of fuel. <br />The spill was the result of accidental flow from the fueling nozzle that <br />mounted on a bracket. The bracket allowed for the nozzle flow control handle <br />and safety plunger to be depressed simultaneously. Sometime between Wednesday <br />noon (the 8th) and Friday forenoon, the nozzle was left hanging on its bracket <br />while the fuel was flowing. The bracket was positioned just outside the crest <br />of the safety berm on [he metal stairs which go up and over the berm. We view <br />the event as being highly unlikely to reoccur. However, all similar nozzle <br />brackets will be modified to direct the flow of fluid back within the safety <br />berm. This should be adequate to prevent any reoccurrence of the situation. <br />The spilled material is currently in No-name drainage and may eventually <br />reach Trapper's sediment control structures. The sediment control structures <br />consist of a series of three dams and one sediment basin. However, the drainage <br />is presently intercepted by an active pit. Additionally, most of the contami- <br />nated area of the drainage will be mined through in the near future. In the <br />event the diesel fuel appears capable of reaching our sediment control ponds, <br />corrective measures will be taken. These could include diversion of drainage <br />flows on to spoils, chemical treatments, skimming and/or pumping of sediment <br />pond water. <br />Presently, the portion of the spill <br />is being contained and will be disposed <br />sources of surface and/or ground water. <br />GMS/js <br />cc: Floyd Nichols (EPA) <br />F.
