Illegal dumping Montgomery, MD

This happened in Montgomery County, MD, USA. We recently moved into a community that doesn’t have a dumpster. We mistakenly disposed of about 50 pounds of flattened cardboard boxes and some household trash in the neighboring community’s dumpster. A resident took a picture of our license plate. We won’t do it again. I’m trying to understand what the most likely outcome is if they report it. I’m very nervous.
