Order No.: DEQ 17-2010 Filed with Sec. of State: 12-21-2010 Certified to be Effective: 12-21-10 Notice Publication Date: 9-1-2010 Rules Amended: 340-041-0033 Subject: The rule revision withdraws the human health “water and fish ingestion” for iron and manganese from Oregon’s water quality criteria contained in Table 20 and incorporated into rule by reference in OAR 340-041-0033(2). In addition, the rule revision withdraws the “fish consumption only” criterion for manganese as it applies to freshwaters of the state, leaving this criterion in place as applicable to saltwater only. DEQ and EPA use Oregon’s water quality standards to implement Clean Water Act programs, which include assessing Oregon’s water quality and developing and enforcing wastewater discharge permits, Total Maximum Daily Loads and water quality certifications.
