Need assistance with a mod that removes bedrock fog.

As per the title I'm trying to make a mod that get's rid of that atrocious fog. However my modding skills are limited to blocks recipes and mobs I have no idea what I have to do in order to get rid of that fog.

Help is appreciated. thanks.

I guess I'm going to have to start checking optifine's thread allot more, I didn't know it was already removed.
