First, thank you for your comments. You're exactly right. We have more than 5,000 employees who are working very diligently to provide safe, reliable and affordable energy to this whole country. They take that responsibility very seriously. I commend them for what they do on behalf of Canadians.
We expanded these monitoring wells and pumping wells because we did identify that there were gaps in the seepage interception system that was initially installed as part of the original design for Kearl. We identified those gaps. We want to be quite prudent in mitigating those gaps. We've significantly expanded it. We are expanding it out of the abundance of caution. We're taking a very conservative approach.
When you look back at where we were at the beginning of this year, at the time the EPO was issued, relative to where we expect to be at the end of this winter season, we will have tripled the size of that seepage interception system. We will have tripled the number of wells we use to ensure that there is no adverse impact to the environment or wildlife or waterways.
We take that very seriously. We're going to do what it takes.
