AT&T on Wednesday signaled it will resolve a yearslong legal struggle over abandoned telecommunication cables contaminating Lake Tahoe, and remove the disused lines. The California Sportfishing Protection Alliance filed suit in 2021 over the cables that it said were leaching toxic lead into the lake that bridges California and Nevada. The two cables, about 8 miles long, are at the bottom of the lake and contain over 68 tons of lead. The federal case was advancing through court when both the alliance and AT&T on Wednesday filed documents in support of a consent decree. A hearing on that decree is set for Nov. 7.
