Eliminating static charges can be a real pain in the butt. First thing I would do is figure out where the charge is being generated. 
Certain countertop laminates can generate a lot of static as can some clear polycarbonates. In the past I have found that a copper mesh product sold by Lee Valley as a slug repellent is very useful for building static drains. Make sure there is enough paint removed to provide a good metal contact. 

Anyhow if it's coming from the bench top I would put the mesh or brass shim stock under the unit mount. If it's coming from you then a strip along the front of the bench would help drain the charge as you lean against it. 

Anyhow once you decide on a plan connect all your drains with a SINGLE wire and run that to a ground point such as a copper pipe. I wouldn't use a ground that could ever possibly reverse such as a neutral in an electrical box. I live in the country and I have measured voltage on my neutrals against earth ground. 
As I said connect it all with a single wire as you don't want to accidentally create a ground loop.

There are a couple of things that you can do to help with static electricity. First wipe down the outside of the measure with a dryer sheet this often helps. The best thing to do is get rid of as much plastic as possible. Get rid of the plastic drop tube and make up a new one out of brass or stainless. For powder bottles get some fine graphite and rub it into the inside of the bottle until you can barely see through the bottle this really helps with static build-up on dry days.

Oh I forgot to mention for polycarbonate, such as your hopper tube, there is an antistatic spray ( look in the laundry soap area at the grocery store) that essentially leaves a conductive film after the carrier dries.

Concrete should be a good ground ( this may actually be part of the problem) as long as there is a path between the measure and the concrete. ie if you have added an insulator such as the a piece of plywood the measure is mounted to then that is clamped to the concrete then you may have  all the ingredients for static buildup. Concrete has a typical strong negative potential, polycarbonates have a typical positive potential and every time your hand passes by the tube operating the lever more electrical charge is created. Static electricity is simply an expression of the difference of electrical potential between two objects.

I'm curious about this from another aspect.   We have all heard the stories about static and BP, though no one I know of has ever heard of a plastic powder bin exploding.

static build up affecting the powder drop is new to me but it sounds more logical.

I have been using the Redding measures for years, and have several of them.   However a couple years back I bought a rather large (by my standards at least) quantity of 4759 which since I have gotten back to shooting centerfire has been my primary powder.  I have had problems too with drop charge issues.  I have always attributed them to the powders stick-like granules wedging in the plastic drop tube throat since giving the measure a little tap seems to help with consistency.  
I have thought of reaming and polishing the plastic drop tube to open the throat up a little.  Now I'm wondering if static is a contributing factor as well. 
Does anyone make an aftermarket brass or copper drop tube for the Redding measures.  if sprayed in the plastic hoppers; how long does the anti-static spray commonly last?

Yep! CBA Nationals. It wasn't pretty!

Verl Sigman won the Plain Base Championship.

I had about 40 cases loaded with powder when I looked into the cases before placing a wad in the case mouth I noticed that not all the charges appeared equal. That's the point that I quit it seemed to me to be a complete waste of powder and lead and primers to continue on. I brought those home and weighed them yesterday the charges ran from 12.5 grains to 5.4 grains the powder measure was set to drop 11.8 grains.

The powder was sticking to the inside of the powder chamber of the powder measure and I guess building up then now and then maybe a big clump would pull loose and fall into the case just guessing on this part. 

I bought some dryer sheets and also some static free spray neither of which had any immediate effect that I could tell. Graphite seemed to have the most effect so far I did ground the powder measure to the steel part of my work bench and have been measuring charges now and then. It is getting better for  a while but then begins to vary the charge weights a couple of tenths and still has powder clinging to the inside of the powder chamber. This is just a small amount of powder granules but I suppose that they would add up after time. 

If I ever get this measure back to a useable condition it will go to a backup mode and I will carry a scale along with it. I'm starting to think about sodering a nail to a small case and cut it back to get the desired weight dip and dump, dang sure be more accurate than what I now have.
