April 3, 2019 — The Trump administration is quietly reviving a long-stalled effort by state regulators to loosen pollution standards where fish spawn. The Alaska Department of Environmental Conservation proposed the rule change more than a decade ago to change how it enforces the federal Clean Water Act.
After a dozen-year hiatus, it’s making its way through the Environmental Protection Agency’s rule-making process. But opponents warn if the EPA gives the 2006 “mixing zone” rule the thumbs-up, it could help pave the way for controversial projects like Pebble Mine.
The Clean Water Act is the primary tool used by the feds to regulate water pollution. Industry often argues these standards are difficult to meet.
“Alaska’s a beautiful, pristine place, and there is no pollution and certainly the background water quality is excellent,” said Frank Bergstrom, an Alaska mining consultant with 40 years of experience. “So if you follow the Clean Water Act to the detail, you pretty much have to discharge distilled water.”
That’s overstating the state’s water quality standards. Basically the limits are designed to prevent water bodies from being degraded. But years ago, Alaska and other states took the industry’s view in mind when it came up with “mixing zones.” This compromise allows things like wastewater plants, mines and oil refineries to exceed water pollution standards in designated areas.
