New Stormwater Regulations in Eastern Washington

Posted: Updated:

RICHLAND, Wash.- New regulations are going into effect for how cities deal with stormwater runoff.

Storms like the one that hit the region Tuesday leave millions of gallons of water flowing through the sewer system, and with it, all sorts of pollutants.  Much of that ends up in the river.  

Starting Thursday, the state will begin regulating stormwater throughout Eastern Washington.  

Many officials say they're adapting as required.

"We have a head start on it, and we'll be working on the other ones, it'll be phased in each year as we go along.   It's a five year permit," said Ray Carlson with the City of Richland.

Stormwater runoff is considered the number one pollutant to the state's rivers.
