A third former Westward Seafoods employee has received a suspended sentence for falsifying emissions data at the company’s Unalaska plant.

A U.S. District Court judge sentenced Bryan Beigh to three years probation and a $750 fine on Tuesday. Beigh was an operator at Westward’s powerhouse during the alleged cover-up from 2009 to 2011.

Beigh was accused of using a magnet and drill to make air emissions monitor spin and appear operational, when in fact, they were never turned on.

Two of Beigh’s co-workers were accused of conspiring to keep the monitors off, and of passing fake data to regulators. Raul Morales and James Hampton were sentenced to several weeks of prison time, along with fines, earlier this month.
