Mark West Quarry Faces Hefty Fine for Polluting Salmon Habitat

Bohemian

A Sonoma County mining company faces a $4.5 million fine for allegedly allowing over 10 million gallons of tainted water to flow into a creek, damaging the habitat of endangered salmon.

In a September press release, the North Coast Regional Water Quality Control Board announced that, at a Dec. 2 meeting, the agency’s board would consider approving a $4.5 million fine against the BoDean Company, Inc. for numerous alleged violations of the Clean Water Act at the company’s Mark West Quarry several years ago. The North Coast water board is one of nine similar boards around the state charged with enforcing a variety of environmental laws.

Water Board staff first identified the problem in December 2018, when they noticed “sediment-laden stormwater” in Porter Creek downstream from the 120-acre quarry, which is used for hard-rock mining and materials processing. Over the next five months, Water Board officials visited the quarry 15 times total, documenting numerous similar incidents. All told, Water Board prosecutors estimate that 10.5 million gallons of tainted water flowed from the mountainside quarry into Porter Creek, which feeds into the Russian River.
