Our View: Let's keep monitoring imported mercury levels

Just across the Idaho-Oregon border — 100 miles upwind of Boise — a cement plant emits up to 2,153 pounds of mercury a year.


That's more than a ton of a poisonous metal that threatens damage to the kidneys and the nervous, digestive and respiratory systems. The risks are particularly acute for young children, who can suffer brain damage and learning disabilities with high doses to mercury.

And the threat sends a clear signal to the elected officials who are charged with protecting the health of our children. Mercury's dangers come from many sources — not just the targets that are easy to identify and easy to oppose.

On Aug. 9, Gov. Jim Risch went after an easy target: coal-fired electric plants. He rejected a federal program that would have encouraged utilities to build mercury-emitting coal plants in Idaho — provided they can show they've made progress reducing mercury emissions in other states.

Risch made the right call, but this one was low-hanging political fruit. As one of only three states without a coal-fired plant,
Idaho stood to gain nothing by joining a program that promised to clean up power plants in other states. That point wasn't lost on 33 of Idaho's 35 senators, who urged Risch to reject the feds' rule. In southern Idaho's Magic Valley, community leaders crossed ideological and political lines to fight California-based Sempra Energy's proposal to build a coal-fired plant.

Risch's decision carries some impact. He has allowed the state to rewrite its energy plan and figure out what kind of coal-fired plants it would allow, "to have Idaho's destiny be Idaho's decision," as Risch Chief of Staff John Sandy said.

But the decision doesn't remove the mercury threat. On Aug. 3, six days before Risch rejected the relaxed rules on coal-fired plants,
Oregon's Department of Environmental Quality revealed emissions from Ash Grove Cement's plant in Durkee, Ore. The 2,153-pound emissions are 10 times higher than the pollution from a coal-fired plant such as Sempra's proposal.

The state has tools at its disposal, namely the Idaho Department of Environmental Quality's monitoring program. The state measures mercury in winds that blow from gold mines in
Nevada, in fish, in sediment at reservoirs and in snowpack near the Pomerelle ski resort close to the Nevada border. The state is doing a "remarkable job" tracking mercury's many sources, said Justin Hayes of the Idaho Conservation League.

That's high praise from an environmental group sometimes at odds with government agencies. But then again, monitoring Idaho's imported mercury problems should not be a partisan issue. Even in a Statehouse with a pro-business, anti-regulatory mindset, the DEQ's monitoring program deserves support from the same bipartisan legislative coalition that successfully fought the Sempra plant.

When mercury pollution comes from out of state,
Idaho is in the awkward position of trying to influence their neighbors' regulatory decisions. Hayes has a good point; if Idaho is going to take that tack, the state's experts need iron-clad evidence. Oregon disclosed Ash Grove Cement plant's mercury emissions, but that doesn't absolve Idaho of its need to monitor mercury. It only underscores the value of monitoring.
