Oregon DEQ objects to draft EPA permits on 4 lower Columbia River dams

The Oregon Department of Environmental Quality submitted a letter on Friday to the U.S. Environmental Protection Agency objecting to EPA’s recently released draft water quality permits (known as NPDES permits) for four federally operated dams on the Lower Columbia River.

DEQ Director Richard Whitman said the agency objected to the lack of requirements to address the dam operations' effects on temperature and total dissolved gas levels in the Columbia River.

Under Section 401(a)(2) of the Clean Water Act, EPA is required to hold a hearing to address DEQ’s objections.

"Oregonians want and expect protections that ensure safe and healthy water in the Columbia River," Whitman said. "Oregon DEQ intends to continue using its authorities to ensure water quality is protected in the Columbia. ”
