General Construction Sequence
1. Prior to earth disturbance activities, appropriate erosion and sedimentation controls will be
in place to prevent sediment from leaving the subject property.
2. Seed any former cropland areas that do not have a permanent dense vegetative cover.
Install the proposed 25-foot tree planting area along the northern and western perimeters.
3. Install interceptor channel downslope of areas to be stripped. Interceptor channel will be
extended as overburden stripping progresses.
4. Commence overburden removal.
5. Concurrent with the beginning of overburden removal, commence construction of the berm
along 106th Street to provide a sediment barrier. This berm should be seeded (temporary
or permanent depending on the weather) immediately upon completion. Silt fence will be
installed, if necessary, until berm outslopes are stabilized.
6. Continue overburden removal activities.
7. Seed all berms and other affected areas that are not active mining areas as soon as final
grade is attained.
8. Temporary erosion and sediment controls, such as the channels and silt fences, will remain
in place until the contributing drainage areas are stabilized. These controls may be
removed after the upslope areas are vegetated or the drainage area is eliminated by the
progression of mining activities.
9. Upon completion of all mining activities, final grade side slopes not inundated at no steeper
than 3 to 1 (horizontal to vertical).
10. Concurrent with reclamation sloping and grading activities, install rock stabilization along
the lake water level.
11. Revegetate site in accordance with the plans as described on Drawing 2, Erosion and
Sedimentation Control and Planting Plan - Post Mining, which is contained in the Mueller
Property North Sand and Gravel Operation Erosion and Sediment Control Report, located
on page 6-4 of this Construction Plan.

Notes: Hypothetical timeline for Mueller Property South Sand and Gravel only.
Actual commencement of activities is contingent upon approval of the proposed surface mining operation.
Actual work will commence within approximately 180 days after receiving approval of the proposed application.
Actual mining duration dependent on local market conditions once activities begin.
