Reversing the district court's grant of summary judgment in favor of the insurer, the Tenth Circuit found that exclusions (j) 5 and (j) 6 were ambiguous as applied to the facts of the case. MTI, Inc. v. Emplrs. Ins. Co., 2019 U.S. App. LEXIS 2543 (10th Cir. Jan. 25, 2019).

Western Farmers Electrical Cooperative (WFEC) owned cooling towers which were serviced by MTI, Inc. Wausau provided a CGL policy to MTI.

In 2011, MTI found that anchor bolts in Cooling Tower 1 were corroded. WFEC hired MTI to make repairs by installing new anchor castings with anchor bolts and anchor adhesive.

On May 23, 2011, MTI employees removed all of the corroded anchor bolts in Tower 1. Because the adhesive applicator had not yet arrived, MTI did not immediately install new anchor bolts. On the night of May 24, strong winds struck the tower, causing it to lean and several structural components broke. Due to the extent of the structural damage, removal and replacement of the tower was determined to be the only viable option.
