That's odd. Our only "pollution pump" is the secondary air injection pump at the front of the engine, it has no ground to the chassis.

The main block ground is a bare cable from the block to the chassis, it's down near the power steering pump, driver's side of engine block - if THAT is what you refer to, then yes, it is an issue.
Again, James and I circumvent that jumper with the mod in the link I provided.
