567—53.7 (455B) List of protected water sources. The following list identifies water sources designated as protected sources under this chapter. Each listing includes the name of the surface water or groundwater source designated, the geographical areas affected, the specific purposes for designating the source, and special limitations imposed or recommended to achieve the purpose of the protected source designation. The listing may also include any special monitoring requirements and may specify a date by which the department must review the designation of the protected source.
	 53.7(1) Ralston Site, Linn County. The area within a one-mile radius of a point which is 600 feet south of the midpoint of the northern edge of Section 2, Township 83 North, Range 7 West in Linn County is a protected water source. Any new application for a permit to withdraw groundwater or to increase an existing permitted withdrawal of groundwater from within the protected water source area will be restricted or denied, if necessary to preserve public health and welfare or to minimize movement of groundwater contaminants from the Ralston Site. The Ralston Site is identified in the Registry of Hazardous Waste or Hazardous Substance Disposal Sites pursuant to Iowa Code section 455B.426.
Withdrawal of groundwater from within the protected water source area may also be restricted or denied from what would otherwise be nonregulated wells, if necessary to preserve public health and welfare or to minimize movement of groundwater contaminants from the Ralston Site. The Linn County health department will refer any application for a construction permit for a private well within the protected water source area to the department’s water supply section that will, after consultation with the department’s IGS, determine whether the proposed well will be allowed.
	 53.7(2) Reserved.
Note:  When protected sources are designated they will be listed as part of this rule.
