Gov Delivery

On Dec. 12, 2013, the Oregon Environmental Quality Commission adopted revisions to the state’s toxics water quality standards. The amendments address EPA’s Jan. 31, 2013 disapproval of several aquatic life toxics criteria, including criteria associated with 11 pesticides and with selenium. The rulemaking also re-instates criteria for arsenic and saltwater criteria for chromium VI, which had been omitted from the table in error during an earlier rulemaking. In addition, , DEQ consolidated all the effective aquatic life toxics criteria into one new table (Table 30).

For more details on the revisions, please see DEQ’s “Corrections and Clarifications to Toxics Water Quality Standards Rulemaking” web page at: http://www.deq.state.or.us/wq/standards/StandardsClarification.htm.
