The U.S. Environmental Protection Agency plans to release the non-cancer dioxin assessment by the end of January 2012.
Congressmen, including U.S. Rep. Dale Kildee, D-Flint, urged the EPA in April to release the assessment after the agency missed its end of 2010 deadline to file a report about dioxinís health effects. According to a letter more than 70 Congressmen signed, Americans have waited 20 years for the report.
After the EPA releases the non-cancer assessment, it will finalize the cancer report as quickly as possible, according to an EPA statement.
The Science Advisory Board on Friday decided to split the assessment into two portions in its final review of the EPAís Reanalysis of Key Issues Related to Dioxin Toxicity and Response to National Academy of Science Comments.
Dioxins are toxic chemical byproducts of manufacturing combustion. World levels have declined since the 1970s. The chemical can enter the food chain through contaminated soil, and the EPA for years has worked to clean up contamination.
The advisory board reported the EPA presented a "clear and logical reanalysis document" and the agency selected comprehensive scientific literature for its assessment.

How many times have I seen this headline before? And now they're not going to re-access dioxin for cancer until a later date (ahem: indefinitely), but only non-cancer causing disease? That should bring it down to about 73 ppt exposure. Cancer effects would lower it to around 3 ppt. And how much is in this watershed, courtesy of Dow? Thousands, tens of thousands, and even a 1 million ppt. hit.
The news needs to look into the new discharge permit Dow is about to receive from the state. They have applied for an increase in toxic discharge to the Tittabawassee, which will flow to all of our communities drinking water supplies. This permit will also grant a critical reclassification of their chemical waste incinerator to a Commercial Hazardous Waste Combuster for other industries.
I thought the state and EPA were trying to clean up Dow's pollution, not grant permits to increase the amount. Cancer anyone?
