Radioactive dump that burned in Nevada had past troubles

LAS VEGAS (AP) — The operator of a closed radioactive waste dump that caught fire in southern Nevada had trouble over the years with leaky shipments and oversight so lax that employees took contaminated tools and building materials home, according to state and federal records.

The firm, now called US Ecology Inc., had its license suspended for mishandling shipments in the 1970s — about the same time that state officials say the material that exploded and burned last weekend was accepted and buried.

Nevada now has ownership and oversight of the property, which opened in 1962 near Beatty as the nation’s first federally licensed low-level radioactive waste dump and closed in 1992. State officials said this week they didn’t immediately know what blew up.

A soundless 40-second video turned over by US Ecology to state officials showed bursts of white smoke and dirt flying from several explosions on Oct. 18 from the dump in the brown desert about 110 miles northwest of Las Vegas.
