Chapter 468B — Water Quality

ORS 468B.064 Follow-up assessments of waters of state that exceed numeric temperature criteria

(1)

The Department of Environmental Quality may perform follow-up assessments of waters of the state that are included in the 1994-1996 list pursuant to section 303 (d) of the Federal Water Pollution Control Act, P.L. 92-500, as amended, for exceeding numeric temperature water quality criteria. The department shall give priority in performing follow-up assessments to those waters of the state listed primarily on the basis of temperature data from 1991 to 1994 and for which follow-up data are now available. The department may use follow-up data collected by a watershed council, university, soil and water conservation district or any other individual or group using data collection protocols approved by the department.

(2)

Subject to available resources, the department shall act promptly to update the list developed pursuant to section 303 (d) of the Federal Water Pollution Control Act, P.L. 92-500, as amended, when appropriate based on the follow-up assessments under subsection (1) of this section.
