A public hearing on the new draft Hanford Facility Dangerous Waste Permit will be at 6:30 p.m. Wednesday.
The hearing at the Richland Public Library, 955 Northgate Drive, will be the fourth held by the Washington State Department of Ecology.
Hearings in May in Seattle and Portland drew more than 300 people combined. The other hearing is tonight in Spokane.
The state has compiled a 16,000-page draft report as the first reissue of its full Hanford permit since 1994.
The permit sets conditions for inspections, spill response, emergency management plans and waste acceptance criteria for hazardous chemical waste, including chemical waste mixed with radionuclides.
At the Seattle meeting the crowd had questions about the vitrification plant and general comments about Hanford environmental cleanup.
At the Portland meeting, concerns were raised about bringing additional waste to Hanford.
More waste is not expected to be brought to Hanford for at least a decade, with a few exceptions, including for submarine nuclear reactor compartments. If more waste is brought to Hanford, the permit would need to be modified.
