Hey, I'm a bit late, but since I think a lot of modder have this problem on object using alpha material, i'm going to answer you.
The black line you see is the right side of your texture starting to repeat (tiling) in the lower resolution mip map. The further the distance the more the problem because when the texture resolution is reduce at each mip map, the left side of your UV is in between a black pixel and a transparent one.
An easy trick to solve the problem in this instance is to "unstick" your UV from the left border of the texture by using something like a 5 pixels margin.

I hope i'm clear.
