~ No person shall apply lawn fertilizer when the ground is frozen.
~ No person shall cause fertilizer to be applied to or run onto any impervious surface including parking lots, roadways, and sidewalks. If such application, occurs the fertilizer must be immediately contained and collected and either legally applied to turf or placed in an appropriate container.
