Gov. signs new suction dredge gold mining law

California Gov. Jerry Brown has signed into law Senate Bill 637 to protect California’s water supplies, wildlife and cultural resources from the damaging effects of suction dredge gold mining.

The new law requires that all small-scale miners using motorized suction pumps obtain a Clean Water Act Permit from the State Water Resources Control Board before mining in California waterways.

“This is a great victory for all of us concerned about clean water and healthy fisheries,” said Elizabeth Martin of the Sierra Fund.

“We are very pleased that our tribal fisheries and sacred sites will receive additional protections from the ravages of gold-mining clubs who have been damaging our resources for decades,” said Josh Saxon, council member of the Karuk Tribe.

The legislation affects suction dredge mining, high banking and any other form of mining that relies on motorized suction pumps to process materials from the banks or beds of rivers and streams.

Suction dredges are powered by gas or diesel engines that are mounted on floating pontoons in the river; attached to their engines is a powerful vacuum hose, which the dredger uses to suction up the gravel, sand and mud from the bottom of the river.

The suctioned material is sifted in search of gold. Similarly, high banking suctions water to process material excavated from riverbanks, causing erosion and sediment problems, as well as affecting cultural sites.

Dredging and high banking alters fish habitat by changing the river bottom and often reintroduces mercury, left over from historic mining operations, to the waterways threatening communities and fisheries. These machines can turn a clear-running mountain stream into a murky watercourse unfit for swimming or fishing.

The measure comes after nearly a decade of litigation among tribes, conservationists and miners. A moratorium on the environmentally destructive practice has been in effect since 2009, but recent court decisions have cast uncertainty on it and prompted clarification from the legislature.

Senate Bill 637 was authored by Sen. Ben Allen (D-Santa Monica) and sponsored by The Sierra Fund. The bill provides clear authority to the State Water Resources Control Board to permit or deny small-scale suction dredge mining in order to maintain water-quality standards.

The issue has implications for the economy as well as the environment.

“For our members, this is about protecting jobs and family-owned businesses which rely on healthy salmon fisheries,” said Glen Spain of the Pacific Coast Federation of Fishermen’s Associations, the West Coast’s largest trade association of commercial fishing families.

The Sierra Fund and the Karuk Tribe have been working with the Center for Biological Diversity, Pacific Coast Federation of Fishermen’s Associations, Friends of the River, Environmental Law Foundation, Upper American River Foundation, California Sportfishing Protection Alliance, Foothills Anglers Association, North Fork American River Alliance, Klamath Riverkeeper and the Central Sierra Environmental Resource Center for several years to reform small-scale mining laws and regulations.
