[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 main stem Columbia
River (see Figure 1) must be managed to protect the designated beneficial uses
shown in Table 101A (November 2003).
(2) Designated fish uses to be protected in
the main stem Columbia River are shown in Table 101B (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
340-041-0101: Table
101C.
(b) In addition to the
salmonid spawning areas shown on Table 101C, 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 and shellfish harvesting use is to be
protected in the portion of the main stem Columbia River designated for these
uses in Figure 101A (August 2016).
