My recollection is that the rate of newly identified sites has dropped off, but we're still assessing those sites. There's a choice to be made each year with the dollars. Do you invest them in remediation of existing sites, or do you invest them in assessing sites that you know you're responsible for but for which you've yet to get the details? There was a push to get some cleanup done on the remediation front, but that balance changes every year.
