Steep Fines--I don't think so. I've been around a long time and never heard of that bureaucracy. And filling a hole with grass clipping which are decomposing to dirt. It's already dirt. You must be very young or have poor information on laws. It might be unlawful in some states to use as a untreated landfill filling it with trash and garbage. But a hole on farm land...This is the type of legality that makes attorneys rich and farmers poor.
