<br />Wrecked or ruined machinery is stored if it has salvage value <br />or hauled to disposal which may be recycling if appropriate. <br />Spare items such as pipe are ordinarily stored in locations <br />where it won't be damaged or destroyed in the course of operations. <br />This usually lends itself to reasonably neat and restricted areas. <br />Diesel fuel can be stored in a 2500 or 3000 gallon container <br />(seldom used because fuel is brought on site in a service vehicle <br />under most circumstances) with a bermed overflow or failure contain- <br />ment. Nearby are stored oil drums and lubricant containers. Approp- <br />riate containers (containing light fluids) have drip collectors. <br />The lubricant vessels will be under a roof to keep precipitation <br />from accumulating in the drip collectors. Refueling and lubrication <br />of equipment is conducted next to this storage location if conven- <br />ient. Collection containers or vessels are used when oil changes <br />are done and even during other maintenance when there is danger of <br />spill, loss, or overflow. Waste oil is collected and stored in <br />drums which are elevated off the ground. The drums are transported <br />for recycling as required or used in waste oil heating systems. <br />The only other occasion where lubricant loss might occur is <br />when a hose might break. This could be anywhere equipment might <br />operate and the only (though incomplete) remedy would be to keep, <br />some absorbent on the piece of equipment to soak up as much of the <br />spill as possible. Then it could be shoveled up and taken to waste <br />disposal. <br />Oil drums and other metal containers will be placed on pallets <br />or other raised surfaces so as to minimize corrosion of their bases <br />and will be covered or sealed so as to prevent accumulation of <br />water in the contents. <br />e.) Spill Prevention and Response Procedures - The only spills <br />that need to be guarded against are the fuel and lubricant spills <br />and the methods of handling them have been described in the prior <br />section. <br />f.) Best Management Practices <br />1.) Stormwater Diversion - The 3 Level portal and dump <br />area are not subject to stormwater runon which is naturally di- <br />verted because the structures are on a scree or talus slope. No <br />runon or runoff has ever been seen. <br />The 6 Level portal and dump area does have some runon <br />because the access road comes downhill to the dump. The road has <br />been water barred and those water bars need to be maintained. Prob- <br />ably placing a culvert just above the last steep slope onto the <br />dump would better insure that this source of runon will be checked. <br />Concern has been expressed that runon could occur from the slope <br />above the dump. This has never been seen to occur but a diversion <br />ditch could be constructed to direct such waters to the natural <br />drainage down Deadman Gulch. <br />The Deadman Gulch drainage and a small side drainage <br />merge right on the 6 Level dump. It is planned that a pipe with <br />a wye will be emplaced in a steeply inclined trench across the <br />dump with the pipe extending down Deadman Gulch at a gradient which <br />will put the discharge into the natural channel. This will divert <br />runon from the two natural drainages and pass it through the dump <br />(5.) <br />
