Current through Register Vol. 63, No. 6, June 1, 2024
Section 340-041-0320 - Basin-Specific Criteria (Umpqua Basin): Beneficial Uses to Be Protected in the Umpqua Basin[Note: The amended beneficial uses designated in this rule, adopted by the Environmental Quality Commission on November 16, 2023, are not applicable for Clean Water Act purposes until approved by the U.S. EPA. For applicable uses prior to EPA approval see "Beneficial Uses of Oregon's Waters" on DEQ's Water Quality Standards website (https://www.oregon.gov/deq/wq/Pages/WQ-Standards-Uses.aspx).]
(1) Water quality in the Umpqua Basin (see Figure 1) must be managed to protect the designated beneficial uses shown in Table 320A (November 2003).(2) Designated fish uses to be protected in the Umpqua Basin are shown in Figures 320A, 320B, 320D and 320E (October 2023).(3) For purpose of protecting active resident trout spawning areas, as required by OAR 340-041-0016 (1): (a) The dissolved oxygen spawning criteria will apply to the salmonid spawning locations and times shown on OAR 340-041-01320: Figure 320E.(b) In addition to the salmonid spawning areas shown on Figures 320E, DEQ will determine where additional active spawning areas used by resident trout occur as data becomes available. DEQ will identify additional spawning habitat and areas determined to be active resident trout spawning areas in a publicly available inventory. The determinations recorded in the inventory will be incorporated into the designated use tables and maps in OAR 340-041 periodically through rulemaking. When resident trout spawning is determined to be an existing use based on the best available data and is added to the resident trout spawning inventory, DEQ will apply the spawning criteria for dissolved oxygen to protect the existing trout spawning use.(4) Coastal water contact recreation use is to be protected in all marine waters adjacent to the Umpqua River and in coastal waters designated in Figure 320C (August 2016).(5) Shellfish harvesting use is to be protected in all marine waters adjacent to the Umpqua River and in coastal waters as designated in Figure 320C (August 2016).[NOTE: View a PDF of referenced Tables and Figures by clicking on the "Tables" link below.]
