		5.2.3.1	The areal extent of the Cheyenne, Dakota, and Ogallala aquifers are shown in Figures 3, 4, and 5 respectively of the report entitled "Ground Water Resources Study ‑ Relating to Portions of Prowers, Baca and Las Animas Counties, Colorado" prepared for the Colorado Ground Water Commission by R. W. Beck and Associates, Denver, Colorado, 1967.  The areal extent of Alluvium and Dockum aquifers shall be determined by site specific information and any applicable literature.

		5.2.3.2	The aquifers identified above shall be administered as a single geo-hydraulic system.

		5.2.3.3	New large capacity well permits can be granted by the Commission to appropriate water from any of the aquifers identified above in Rule 5.2.3.1, or from the single geo-hydraulic system, if this appropriation does not unreasonably impair any existing water rights.

		5.2.3.4	For any existing large-capacity well that was constructed and put to beneficial use in compliance with all applicable statutory procedures, and is completed in one, or more than one of the aquifers identified above in Rule 5.2.3.1, an additional large capacity well permit can be granted by the Commission pursuant to Section 37-90-107, C.R.S. for an increase in appropriation, including an increase in irrigated acres. Any such additional well permit shall have an appropriation date based on the date of application for the additional permit consistent with Section 37-90-109, C.R.S., which shall be separate and distinct from the original appropriation for the existing well.
