It's a great question.
I have to refer to the work of my colleagues and the work of even the International Joint Commission. This has been a big discussion recently.
There are certain practices; voluntary incentive programs only go so far. There are practices that have a major impact.
I'll just pick on a few. Winter spreading of manure, for example, is an issue; the requirement to have cover crops to prevent more erosion and phosphorus delivery in the spring; and septic system inspections, routine inspections, or inspections at the time of title transfer, if there is a sale. Those types of specific practices can be regulated.
Beyond that, I'm lumping also into this what I call cross-compliance. I think you've heard a few things here. We have an incentive-based program that we deliver, the clean water program, but we require any landowners, before they're eligible, to complete an environmental farm plan, which Mr. Richardson talked about. It's not a traditional form of regulation, but the cross-compliance, you have to have the conservation farm plan in place first before you're eligible for any help from incentives.
