Hey, good morning.

Paige Browning here.

It's Saturday, and this is Seattle now.

Today we're bringing you the best from the KUOW Newsroom.

First, a story about Seattle's Rainier Beach High School.

It was entirely rebuilt last year on peat soil that scientists found

emits potentially hazardous levels of methane. But a K-O-W investigation found the district

skipped some safety steps to keep methane out of the building. Ann Dornfeld reports.

Rainier Beach High School sits on an ancient peat bog that used to be the floor of Lake

Washington. The decaying plants and animals in peat release methane gas. So before construction

began, scientists measured underground methane levels. In a report to the district, they warned

that methane is colorless, odorless, lighter than air, and is a fire and explosion hazard.

Engineers said they found methane concentrations in at least one place that were higher than 5%, just above the explosive level.

In a report to Seattle Public Schools, engineers said that level of methane meant the district

should take federally recommended steps to keep vapors out of the building. But local law does not

require that, and KUOWW found that the district skipped some of engineers' key safety recommendations.

You see the plumbing and piping over here.

Richard Best heads capital projects and planning for Seattle Public Schools.

Standing outside Rainer Beach, he points out a venting system engineers recommended to funnel underground methane away from the school.
