No conditional use permit for commercial or industrial uses shall be issued unless it is demonstrated that the use is connected to an approved sewer system, overlays a protected aquifer, and the intended handling, storage, and disposal of all chemicals on the site does not permit leaching into groundwater aquifers. The proposed use shall demonstrate the best management practices that are to be employed on the site to contain any spills, drips or seeps that present a conduit for potential groundwater contamination. All containment systems shall be designed with a 25% higher capacity than the total volume of materials on the property.
