1 3.1. Burro Area Mlnes (Reference Maps 2,4,5,6)
' 3.1.1. Bwrro Adit Waste Pilea (Reference Map 4)
SWMP: Grade the waste pile leaving it slightly concave in the center to control
' stormwater migration. Where necessary, the construction, installation and/or
application of contour::, berms, silt fences, straw bales, water bars, fertilizatioNre-
vegetation will be initiated to mitigate stormwater surface erosion and stormwater
migration. All mitigation measures will be done on the original foot-print (affected area)
and in accordance with Federal and State Regulations.

3.1.2. BUITO No. 3 Waste Pile (Reference Map 5)
SWMP: Grade the waste pile leaving it slightly concave in the center to control
stormwater migration. Where necessary, the construction, installation and/or
application of contours., berms, silt fences, straw bales, water bars, fertilizationlre-
vegetation will be initiated to mitigate stormwater surface erosion and stormwater
migration. All mitigation measures will be done on the original foot-print (affected area)
and in accordance with Federal and State Regulations.
3.1.3. Bu1T0 No. 5 Waste Pile (Reference Map 5)
SWMP: Grade the waste pile leaving it slightly concave in the center to control
stormwater migration. Where necessary, the construction, installation and/or
application of contours, berms, silt fences, straw bales, water bars, fertilization/re-
vegetation will be initiated to mitigate stormwater surface erosion and stormwater
migration. All mitigation measures will be done on the original foot-print (affected area)
and in accordance with Federal and State Regulations.
3.1.4. Burro No. 7 Waste Pile (Reference Map 6)
SWMP: Grade the waste pile leaving it slightly concave in the center to control
stormwater migration. Where necessary, the construction, installation and/or
application of contours, berms, silt fences, straw bales, water bars, fertilization/re-
vegetation will be initiated to mitigate stormwater surface erosion and stormwater
migration. All mitigation measures will be done on the original foot-print (affected area)
and in accordance with IFederal and State Regulations.
3.2. Sunday Area Mines (Reference Maps 3,7,8,9,10,11)
3.2.1. Sunday Mine Waste Piles (Reference Map 7)
SWMP: Where necessary, the construction, installation and/or application of contours,
berms, sift fences, straw bales, water bars, fertilizatioNre-vegetation will be initiated to
mitigate stormwater surface erosion and stormwater migration. On final reclamation the
the waste pile will be graded, leaving it slightly concave in the center to control
stormwater migration. All mitigation measures will be done on the original foot-print
(affected area) and in accordance with Federal and State Regulations.
