 So we're at McNary Dam today. We're doing a remotely operated vehicle inspection of all of McNary's main unit intake trash racks. We were asked to look at inspecting the trash racks so engineering and the project could come up with a better estimate of what it would take to refurbish the trash racks and if there's any debris at the bottom of the trash racks that would need to be removed, what kind of volume it is. The ROV is a great option. We don't like to put divers in the water unless absolutely necessary. So we're always looking for any way to do an inspection or work without putting divers in the water just because of the risk factors. You don't have a diver down there that is either put in harm's way or gets cold or meets their decompression obligation. It has a capability of going down to close to a thousand feet but it's mainly set up to do underwater inspections utilizing both the high definition camera and we have a couple of different sonar on it that allow us to see through zero visibility water as well as some underwater measuring tools. The biggest thing is to make sure everything is done correctly and safely. We have certain guidelines that we use to prepare an area prior to operating in. It's all to operate in a safer environment.
