I would share a couple of thoughts. The regulations do put in place a risk-based approach. It's not a one-size-fits-all approach. We recognize that. I think this is where you're going.
On the whole, private grade crossings, which farm crossings are part of, generally speaking tend to be of lower risk than the public crossings in cities, with their high traffic, but that doesn't mean that all private crossings are low-risk. Some are of medium- and high-risk. Those are the remaining 6,000 of the 9,000 that remain as part of the regulations.
The regulations set a spectrum-based approach. There are five levels of risk. Where a crossing falls in that spectrum determines the mitigation measures required to bring risk down to a tolerable level. I think in the vast majority of cases, because we're at a 99% compliance rate, the measures put in place are financially reasonable.
For a small number—the representative from CN in the first hour spoke to it being down to eight—there are cost-prohibitive budgets or estimated costs of between $600,000 and $2 million. They're working with landowners to find practical solutions for those eight. CPKC testified that they're in full compliance.
