Omak Longhouse, PCB & Mineral Oil Spill

Omak, WA | Unauthorized Transformer Dump

On or around July 9, 2015, a spill incident occurred near the Colville Tribes Omak Longhouse, located at 25B Mission Road, Omak, WA. The event was triggered by the theft and improper handling of an out-of-service transformer, which had an approximate 25-gallon capacity of mineral oil.

The transformer was reportedly chained to a vehicle and dragged along Mission Road and North End Omak Lake Road, resulting in intermittent oil discharge along both asphalt and gravel surfaces.
