Dioxin Report Delayed & Huron-Manistee Plan

A report on dioxin that’s more than 25 years in the making… is delayed yet again.

This is the Environment Report. I’m Rebecca Williams.

The Environmental Protection Agency has missed its own deadline to release a major report on the health effects of dioxins. Dioxins are a class of toxic chemicals.

The EPA says dioxins are likely to cause cancer in humans. Since the mid-1980’s, the EPA has been working to define just how toxic dioxins are. Over the years, the agency has released drafts of the report. These drafts have been picked apart by scientists and industry. Then, the EPA goes back to working on it.

Last year, the EPA decided to split its dioxin assessment into two parts. One part will look at cancer risks, the other part will look at non-cancer health risks. The agency had promised to release the report on non-cancer effects by the end of January. But they missed that deadline.

The EPA did not want to be recorded for this story. They would only say they’re “working to finalize the non-cancer health assessment for dioxin as expeditiously as possible.”

People in central Michigan have lived with dioxin pollution for more than three decades. The pollution is largely from a Dow Chemical plant in Midland. We’ve previously reported that EPA’s dioxin assessment could affect how much dioxin Dow might have to clean up.

Michelle Hurd Riddick is with the Lone Tree Council. It’s an environmental advocacy group based in Saginaw.

“We need our government to issue a clear scientific statement and report on the toxicity of this chemical. But unfortunately it appears it’s probably politics as usual. And the monied interests, the lobbyists, they have the access, they have the influence and public health be damned.”

The EPA has been under pressure from industry groups.

In December, the American Chemistry Council asked the EPA to withdraw the dioxin report from interagency review. In a statement emailed to The Environment Report yesterday, the ACC said a draft of the EPA’s dioxin assessment is flawed… and that the EPA has not considered the economic impact of the report.

Two years ago, The Environment Report produced an investigative series looking at why the dioxin cleanup in Michigan has been delayed for so long. The cleanup process has stopped and started for thirty years, with the federal and state governments passing the problem back and forth. In the series, former EPA Administrator Mary Gade said Dow has slowed down the cleanup.

“I think this corporation is hugely adept at playing the system and understanding how to build in delays and use the bureaucracy to their advantage and to use the political system to their advantage.”

In an email statement, a spokesperson for Dow said the company cannot speculate on how EPA’s dioxin assessment would affect their current work. The spokesperson noted that Dow signed a cleanup agreement with the EPA in January 2010, and said, “We are focused on implementing this agreement and working towards resolution.”

Dioxin Delays: A Special Series by The Environment Report


(music bump)

This is the Environment Report.

The U.S. Forest Service has revised its management plan for the Huron-Manistee National Forest. Bob Allen reports there won’t be any new limits on snowmobiling or gun hunting:

In 2010, a federal appeals court told the Forest Service its new plan failed to follow proper rules and law.

The Court agreed with a man who argued the plan promised quiet recreation in certain non-motorized areas of the forest but didn’t deliver on that promise.

Kurt Meister suggested that some of those areas be marked off-limits to gun hunting and snowmobiling.

That set off a firestorm of mostly negative reaction.

After listening to public comment, the Forest Service is changing the way those areas are classified.

That means there’s no longer a high expectation to experience quiet and solitude in those areas.

The plan still must be accepted by the Court.

For the Environment Report, I’m Bob Allen.
