(f) The limits of other physical, chemical, biological or radiological properties that may be necessary for preserving the quality and purity of the waters of the state;

(g) The extent to which any substance must be excluded from the waters for the protection and preservation of public health; and

(h) The value of stability and the public’s right to rely upon standards as adopted for a reasonable period of time to permit institutions, municipalities, commerce, industries and others to plan, schedule, finance and operate improvements in an orderly and practical manner.

(2) Standards established under this section shall be consistent with policies and programs for the use and control of water resources of the state adopted by the Water Resources Commission under ORS 536.220 (Policy on water resources generally) to 536.540 (Approval of voucher claims).
