<br />9. Copies of current MPCA permits. current storm water pollution prevention <br />plan and current NPDES permit <br /> <br />The Storm Water Pollution Prevention Program concentrates on identifying potential <br />pollutants on the construction site and adopting management practices that eliminate their <br />contact with storm water. The following outline was used as a guideline to develop an <br />effective and functional program for pollution prevention. <br /> <br />I. Identify potential sources of storm water contamination on the construction site. <br />A). #2 Fuel Oil <br /> <br />1. Spills during equipment refueling <br />II. Bulk shipment deliveries - overfill <br />III. Broken or leaking fuel lines and hoses <br />B). Lubricating Oils <br /> <br />I. Overfilling gearboxes <br />II. Leaking seals on mechanical equipment <br />III. Engine breather pipes <br />IV. Spills during oil changes <br />V. Improper storage of oil inventory <br />C). Grease <br />I. Over greasing bearings and wear surfaces <br />II. Improper disposal of cleaning towels <br /> <br />D). Aggregates <br />1. Pile runoff not contained on site <br />II. Poor storage technique <br />E). Antifreeze <br />I. Leakage from damaged radiators <br />II. Overfill/spill <br /> <br />2. Run off <br /> <br />A). Whenever possible, plant location is chosen such that site runoff from the <br />immediate plant area is contained onsite by natural impounding. In cases <br />where natural impounding is not available, berms will be constructed to <br />provide containment from immediate plant area. <br /> <br />B). Whenever possible, aggregate piles will be located such that storm water <br />runoff from the pile area will flow into a settling impoundment to reduce <br />turbidity before exiting the site. <br /> <br />13 <br />
