The industry goes further than the regulations require by carrying out inspections on an annual basis, or more frequently than is required, in the case of high-volume outlets. That shows how important this is to us and how cost is not an issue because we don't just do inspections every two years, as the regulations prescribe. Sometimes, we don't even let a year pass between inspections.
Aside from economic considerations, it's important to remember that the pumps are all part of a system that includes underground tanks and pipelines. We must ensure that there are no leaks in the system, from an inventory control standpoint and for the sake of the environment. The pumps are one component of the reconciliation process that allows us to ensure that environmentally speaking, the equipment is in sound working order. Therefore, cost is not a major factor. This is clear, in my opinion, from the industry's performance.
