(A) The groundwater resources of the basalt aquifer in the Ella Butte Groundwater Study Area as described in the Proclamation of January 31, 1985, are classified for statutorily exempt uses (see definition) only. This classification terminates the critical groundwater determination proceeding initiated January 31, 1985, and the Proclamation of the same date issued for the Ella Butte study area;

(B) The groundwater resources of the Willow Creek subbasin outside the Butter Creek Critical Groundwater Area and the Ella Butte Groundwater Study Area are classified for statutorily exempt groundwater uses (see definition), irrigation, municipal, industrial, power development, low temperature geothermal, mining, fish life, wildlife, recreation, pollution abatement, and artificial groundwater recharge; and

(C) Groundwater from the basalt reservoir in a five-mile radius around any municipal well of the cities of Heppner, Ione and Lexington is classified for municipal, group domestic and statutorily exempt groundwater uses (see definition) only. Other uses may be permitted if it is documented that a barrier to groundwater movement separates a proposed well from municipal wells and there will be no interference with municipal wells. Applications for other uses of groundwater within a five-mile radius of a municipal well shall automatically be referred to the Commission for review and consideration of public interest unless the affected city affirms that it is in favor of the proposed appropriation. This classification applies only when the affected city(ies) have a full-time conservation program in effect.
