[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 Mid Coast Basin (see
Figure 1) may be managed to protect the designated beneficial uses shown in
Table 220A (November 2003).
(2)
Designated fish uses to be protected in the Mid Coast Basin are shown in
Figures 220A, 220B, 220I and 220J (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 the following tables and figures in OAR
340-041-0220: Figure
220J.
(b) In addition to the
salmonid spawning areas shown on Figure 220J, 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 Mid Coast Basin
marine waters and in coastal waters designated in Figures 220C through 220H
(August 2016).
(5) Shellfish
harvesting use is to be protected in all Mid Coast Basin marine waters and in
coastal waters designated in Figures 220C through 220H (August 2016).
