AutoCAD Civil 3D :: Layers Stuck In Template?

I am working on the template for my company and making all the styles, labels, etc all consistent to our company standards. This also includes our standards layer names. There are 2 layers that I can't get rid of because they are in use somewhere. C-ROAD-CNTR-STAN and O_PROF-VIEW-TEXT both of these layers do not meet our standards and I can't get rid of them. I went through every style and label to see if I could find where they were being used, but couldn't find them anywhere. I made sure I check the layers for plan, profile, model and section on the display tab of each style. 

Since there are so many styles to go through I wanted to try to narrow it down, so I started a new drawing from the template. I purged all of the styles, purged the layers, but they were still there. I set the object layers all to 0. I made sure that every label style default setting was also set to 0. Then I even created all new styles and labels for everything, did a "replace with" and made sure only the new styles were in use, removed the old styles and did a purge. But these layers still are being used somewhere. I tried using LAYTRANS to translate them into the 0 layer, but it doesn't work. There are no blocks in the drawing that are using these layers.

The only command that works to get rid of them is LAYDEL, but doing that makes me concerned that a setting may not have a layer set up for it and it may cause problems in the future.
 
Attached is a dwg file that I have stripped down as described above. I am using Civil 3D 2012, SP 2. Where a layer is in use? How you can now find where a style is in being referenced?
