The boom in domestic oil production through fracking is posing new risks to Washington’s rails and waterways. The state is taking comments on the initial findings of a marine and rail oil transportation study. Public meetings on the study are attracting busloads of people who want to voice their concerns.

The state Department of Ecology released its draft findings on new risks from oil transportation earlier this month.

Crude by rail transportation has increased dramatically in the last three years, and the trend is expected to continue. The study says 19 loaded trains per week now travel through the state. Three of the five refineries in Puget Sound currently receive oil cars and the other two are expected to do so in the future.
