2. Describe specific erosion control measures to be installed prior to land disturbing activities and during mining to
prevent offsite sedimentation(include specific plans for sediment and erosion control for mine excavatioWnl, waste
piles, access/mine roads, and process areas), and give a detailed sequence of installation and schedule for
maintenance of the measures.Locate and label all sediment and erosion control measures on the mine maps)and
provide typical cross-sections/construction details of each measure.Engineering designs and calculations are required
to justify the adequacy of any proposed measures.
1. Install temporary sediment fence
2. Install gravel construction entrance/exit
3. Install pipe inlet protection & rip rap apron
4. Construct berm and provide seeding & mulching
5. Temporary seeding and mulching of any waste/stockpile remaining in place
for 21 days or more.
3. A)Will the operation involve washing the material mined, recycling process water,or other wastewater handling?
FIYES IN NO
If yes, briefly describe all such processes including any chemicals to be used.
B)Will the operation involve discharging fresh or wastewater from the mine or plant as a point discharge to the waters
of the State?
YES NO
If yes, briefly describe the nature of the discharge and locate all proposed discharge points(along with their method of
stabilization)on the mine map(s).
This site will have 2 de-watering basins installed independently as each phase of
the mine is started. They will be located on the south of the mine and will
discharge storm water/wastewater into an existing farm ditch that currently flows
into existing wetlands. The outlets will be stabilized with rip rap aprons. (See
calculations enclosed for the de-watering basins and rip rap aprons.)
