Why it Matters

At the Department of Ecology Nuclear Waste Program, we work to make sure Hanford’s cleanup follows our state’s regulations to protect our air, land, water, and citizens.

It is important that permit conditions are accurate and allow compliance with the regulations. We invite you to comment on this permit modification before we make our decision.
