(1) A rule adopted by the Water Resources Commission under ORS 537.730 shall:

Any number of ground water reservoirs which either wholly or partially overlie one another may be included within the same critical ground water area.
(b) Contain a provision requiring a periodic review of conditions in the critical ground water area. The review shall be in sufficient detail to evaluate the continuing need for the critical ground water area designation and shall occur no less frequently than once every 10 years.
(2) In adopting the rule, the commission shall consider any orders or permits applicable to the reservoir issued by the governing board or State Geologist of the State Department of Geology and Mineral Industries under ORS chapter 522.
(3) A rule by the commission under subsection (1) of this section may include any one or more of the following corrective control provisions:

(b) A provision determining the permissible total withdrawal of ground water in the critical area each day, month or year.
(c) The disposition of any application for a water right permit for the use of water in the area that is pending at the time the commission initiates the rulemaking process or that is received during the rulemaking process.

(f) A provision determining the permissible change in thermal characteristics of ground water in all or part of the critical ground water area each day, month or year. Insofar as may be reasonably done, the Water Resources Director shall apportion the permissible total temperature impact among those appropriators whose exercise of valid rights in the critical area affect the thermal characteristics of the ground water, in accordance with the relative dates of priority of such rights.
