Please give some directions from WR to Brimestone!!

I heard you can access Brimstone from Hwy 116 at a Big Blue working Coal Washer on 116 (suppose to be directly below the windmils on 116). It croses TWRA Sunquist area, and you need another permit to come in this way. I think this will bring you into trail 1, but not positive. If anyone has address or gps cordinates of the blue coal washer, I'd love to have it, not from the area, and havent been thru 116, but would like to know how to come thru this way for maybe future rides.
