‘Something dramatically wrong’: Questions but few answers after Longview mill tragedy

Family members of some of the 11 victims who died in last week’s paper mill disaster in Longview want answers on what led to the deadly rupture of a massive tank full of caustic chemicals.

They’re also questioning the safety culture at the mill, and at least two families say they have retained attorneys.

Investigators from the U.S. Chemical Safety Board have been on-site since Wednesday, but a spokesperson for Nippon Dynawave, the company that operates the mill, says the investigation is still “very much in early days.”

OPB spoke to seven chemical safety experts and former investigators about what officials would look for to determine how the rupture happened and what could have prevented it. (Troy Brynelson, Conrad Wilson and Lauren Dake)

Think young people are killing wine sales? Washington industry pros say it’s more complicated

Anxiety has been brewing in the beverage industry around the drinking habits of younger people.

They’re generally drinking alcohol less than people in older generations, which has presented challenges to Washington’s wine industry.

A recent event at Walla Walla Community College’s enology and viticulture program brought together winemakers, industry pros and students to discuss solutions to make wine culture more welcoming to young people.

The biggest barrier to entry? Affordability. (Erick Bengel, NWPB)
