On October 17, 2011 the EPA approved revisions to Oregon's water quality standards for toxic substances that determine how much fish humans can safely consume. The standards for toxics were already stringent and the further decrease will require more advanced treatment technologies and systems. Regional program staff were actively engaged in the review process with the DEQ to provide accurate information on potential impacts to municipal wastewater treatment facilities.
On June 1, 2010, the U.S. Environmental Protection Agency (EPA) disapproved Oregon's New and Revised Human Health Water Quality Criteria for Toxics, which cleared the way for Oregon to continue the rulemaking process whereby the "Fish Consumption Rate" has been increased to the highest levels in the United States.
The 6.5 g/day fish consumption rate has been increased to 175 g/day (24- 8 ounce meals a month).
