MOX Services proposes the construction of a shed and installation of electrical conduit and grounding rods. The shed (approximate size of 16x20 feet) will be located in the northwestern portion of the existing laydown yard and will require pouring a 2-inch thick concrete slab (for a floor) on top of the existing crushed stone laydown yard. Excavation will not be required for shed construction. Electrical conduit will be installed in the existing crushed stone laydown yard to convey power from a diesel generator to the shed and to light towers that will be placed in the laydown yard; no excavation required. Light towers will require the installation of grounding rods 7-8 feet in length. The rods will be driven/pushed into the ground; no excavation required. Ground-penetrating radar will be used to clear the sites prior to rod installation.
