Court says EPA Must Regulate
by Jeremy P. Jacobs
The "parties agree that dams and more than 100 point-source discharges" into the two rivers are the cause of rising water temperatures.
-- Judge Margaret McKeown
Federal judges today sided with environmental groups pressing EPA to set temperature limits in the Pacific Northwest's Columbia and Snake rivers to help endangered salmon and steelhead.
A 9th U.S. Circuit Court of Appeals panel said EPA has failed to develop temperature limits as required under the Clean Water Act.
Rising temperatures caused by dams that stagnate water flows, as well as discharges and climate change, are deadly to migrating fish like salmon. Anything above 68 degrees Fahrenheit makes it nearly impossible for fish to migrate upstream to spawn.
Environmentalists filed the current lawsuit in 2017, using a new legal argument that Washington, Oregon and EPA are required under the Clean Water Act to issue total maximum daily loads, or TMDLs, for not just common pollutants such as agriculture runoff, but also for temperature.
The three-judge 9th Circuit panel upheld a lower court ruling for Columbia Riverkeeper, Idaho Rivers United and other groups, giving EPA 30 days to move forward.
Judge Margaret McKeown, writing for the court, said the "parties agree that dams and more than 100 point-source discharges" into the two rivers are the cause of rising water temperatures.
Moreover, she said, "[t]emperatures are projected to rise with increased human activity on the rivers, furthering endangering salmon and trout populations."
The Columbia and Snake rivers were historically home to some of the most prolific salmon and steelhead runs in the world. Some 10 million to 16 million of the fish returned to the river system every year, and the Snake River, a Columbia tributary, produced nearly half of those runs.
Salmon and steelhead runs plummeted beginning in the 1960s due to several factors: rapid dam building, commercial harvest and other development Greenwire, Sept. 25).
Today, the salmon and steelhead runs on the Snake River are particularly imperiled, leading environmental groups to take new legal action including this case.
McKeown noted that Washington, Oregon and EPA have acknowledged the need for a temperature TMDL. In fact, in the early 2000s, the states and EPA entered into an agreement under which the agency would develop and issue the temperature limits.
Then, in 2003, EPA released a draft of the TMDL but faced significant opposition from other federal agencies.
"Then," McKeown wrote, "nothing happened."
The legal issue in the case concerns where the lack of action constitutes a "constructive submission" by the states that EPA is required to act upon under the Clean Water Act.
The court held that it is.
"Where a state has failed to develop and issue a particular TMDL for a prolonged period of time, and has failed to develop a scheduled and credible plan for producing that TMDL, it has no longer simply failed to prioritize this obligation," McKeown said.
"Instead, there has been a constructive submission of no TMDL, which triggers the EPA's mandatory duty to act," she said.
