Where to dump in Howard County
Alpha Ridge Landfill is where a trailer load goes. Any resident using a trailer or rental vehicle is treated as a commercial customer: a $40 yearly permit and every load crosses the scale. Residents using a rental vehicle may also need a special-exception form approved before unloading, so call ahead.
