An Onalaska man pleaded not guilty to charges stemming from his alleged involvement in a large-scale marijuana growing operation, while a Chehalis man faced similar charges from his alleged involvement in a separate marijuana growing operation but failed to appear in Lewis County Superior Court on Monday.

The scheduled hearings for Lap Lam Chan, 37, and Bu Win, 28, were the second and third cases regarding marijuana grow operation busts to be heard in Superior Court in July.

Chan, of Onalaska, was charged with manufacture of marijuana, maintaining a building for keeping controlled substances and possession of marijuana with intent to manufacture or deliver.

According to court documents, on March 23 a Lewis County Sheriff’s deputy and members of the Washington State Patrol Marijuana Task Force served a search warrant on a property in the 2600 block of Highway 508 in Onalaska.

When law enforcement arrived, they found a large scale marijuana growing operation in a detached barn on the property.

Officers seized 1,137 marijuana plants in various stages of growth, $42,779 in cash, most of it rolled up into bundles, large coolers with marijuana buds inside of them, packaging equipment and marijuana scattered throughout the living room.

When speaking with police, Chan identified himself as the property owner, according to court documents.

At his preliminary appearance on Monday, Judge James Lawler agreed to release Chan on a personal recognizance bond based on his ability to appear in court.
