CRAWFORD, Neb. (AP) — A truck making a delivery to a uranium mining company has overturned and caused a minor hazardous chemical spill in northwestern Nebraska.

Dawes County Deputy Sheriff Scott Swickward says a tankard truck hauling a trailer slipped down a rig early Wednesday morning while delivering a chemical to Crow Butte Resources, Inc. near Crawford. He says the leak resulting from the accident is not a public threat, but nearby residents were evacuated as a precautionary measure.

Swickward says only a valve broke on the truck, causing hydrochloric acid to drizzle out. He says Nebraska hazmat crews have responded to the scene and are working to clean up the spill.

Hydrochloric acid forms a mist that can have an erosive effect on human skin, eyes and other organs.
