Draft Notice of Construction (NOC) Permit - DE14NWP-001, for Rotary Core Sampling Systems for Hanford’s Tanks

The Washington State Department of Ecology invites you to comment on a change to the Hanford Site Air Operating Permit (AOP). The AOP regulates air emissions from Hanford’s tank ventilation systems.

The tanks are in Hanford’s 200 East Area and 200 West Area, near the center of the Hanford Site. The tanks store high-level radioactive and chemical waste remaining from Hanford’s plutonium manufacturing.

The change to the AOP would allow the United States Department of Energy to install up to two rotary core sampling systems for Hanford’s underground tanks.

The rotary core sampling systems are needed to collect samples of solid materials in the tanks so the waste can be managed more safely.
