3. Stonrnwater Quality Controls -Best Management Practices <br />1 3.1. Burro Area Mlnes (Reference Maps 2,4,5,6) <br />' 3.1.1. Burro Adit Waste Piles (Reference Map 4) <br />SWMP: Grade the waste pile leaving it slightly concave in the center to control <br />stormwater migration. Where necessary, the construction, installation and/or <br />' <br />application of contours, berms, silt fences, straw bales, water bars, 1`ertilizatioNre- <br />vegetation will be initiated to mitigate stomtwater surface erosion and stormwater <br />' migration. All mitigation measures will be done on the original foot-print (affected area) <br />and in accordance with Federal and State Regulations. <br /> <br />1 <br /> <br /> <br />1 <br /> <br />3.1.2. Burro No. 3 Waste Pile (Reference Map 5) <br />SWMP: Grade the waste pile leaving it slightly concave in the center to control <br />stormwater migration. Where necessary, the construction, installation and/or <br />application of contours, berms, silt fences, straw bales, water bars, 1'ertilizatioNre- <br />vegetation will be initiated to mitigate stormwater surface erosion and stormwater <br />migration. All mitigation measures will be done on the original foot-print (affected area) <br />and in accordance with Federal and State Regulations. <br />3.1.3. Bunco No. 5 Waste Pile (Reference Map 5) <br />SWMP: Grade the waste pile leaving it slightly concave in the center to control <br />stormwater migration. Where necessary, the construction, installation and/or <br />application of contours, berms, silt fences, straw bales, water bars, fertilizatioNre- <br />vegetation will be initiated to mitigate stormwater surtace erosion and stormwater <br />migration. Atl mitigation measures will be done on the original foot-print (.affected area) <br />and in accordance with Federal and State Regulations. <br />3.1.4. Burro No. 7 Waste Pile (Reference Map 6) <br /> <br />1 <br />ll <br />1 <br /> <br />t <br />1 <br /> <br />SWMP: Grade the waste pile leaving it slightly concave in the cenl:er to control <br />stormwater migration. Where necessary, the construction, installation and/or <br />application of contours, berms, silt fences, straw bales, water bars, fertilizatioNre- <br />vegetation will be initiated to mitigate stormwater surface erosion and stormwater <br />migration. All mitigation measures will be done on the original foot-print (affected area) <br />and in accordance with Federal and State Regulations. <br />3.2. Sunday Area Mines (Reference Maps 3,7,8,9,10,11) <br />3.2.1. Sunday Mine Waste Piles (Reference Map 7) <br />SWMP: Where necessary, the construction, installation and/or application of contours, <br />berms, silt fences, straw bales, water bars, fertilizatioNre-vegetation will tie initiated to <br />mitigate stormwater surface erosion and stormwater migration. On final rat;lamation the <br />the waste pile will be graded, leaving it slightly concave in the cent~3r to control <br />stormwater migration. All mitigation measures will be done on the original foot-print <br />(affected area) and in accordance with Federal and State Regulations. <br />7 <br />
