When I can dump the gray water on the ground I simply remove the plug from the drain inside the pump's temporary tank, the water is drained so the pump never comes on.

Regulations at US National Forests

General Rules For National Forests
CAMPING

Camper holding tanks may only be emptied into approved designated facilities. Many campgrounds in the Forest are not equipped with dump stations, so you may have to travel to nearby communities to find an approved dump station.
Graywater from individual campsites, in small quantities, may be disposed of in the toilet facilities or else taken away from the campground and dispersed on the ground over a wide area.
