Site description

Pacificorp’s Jim Bridger Power Plant is located in Point of Rocks, Wyoming. This plant has three coal ash disposal units regulated by the coal ash rule: the Ash Landfill (200 acres), FGD Pond 1 (93 acres), and FGD Pond 2 (260 acres). All of these disposal units are unlined, with FGD Pond 1 inactive since 2004 as it has met its storage capacity of 1,340 acre-feet. The FGD Pond 2 was rated as a significant hazard potential on September 16, 2016, as well as earlier in 2009.
