es, effects of potential future use on these DRAFT Rev. 3 - April 1996 2.4.12-8 parameters, and applicability and reliability of dewatering systems. If the design bases estimates are comparable, staff concurrence in the applicant's estimates will be stated. If the staff predicts substantially more conservative groundwater conditions and the proposed plant may be adversely affected, a statement of the staff bases will be made. If groundwater conditions do not constitute design bases, the findings will so indicate. For operating license (OL) reviews of plants that have had detailed groundwater reviews at the 26 CP stage, the CP conclusions will be referenced. For reviews of plants that have had detailed groundwater reviews associated with the early site permit review, the early site permit review conclusions will be referenced. In addition, a review of groundwater history since the CP or 27 early site permit review will be indicated and note of any changes in groundwater conditions or 28 usage will be made. For permanent dewatering systems, any additional information regarding soil properties and groundwater conditions gathered during construction will be evaluated to determine the applicability of the assumed CP or early site permit design basis. If no CP or 29 early site permit groundwater review was undertaken of the scope indicated above, this fact 30 will be noted in the OL findings, in addition to the results of the current review. A sample CP or early site permit statement follows: 31 The proposed site lies within a groundwater region which is part of the Piedmont Groundwater Province. Groundwater in the area is derived entirely from local precipitation. The water is contained in the pores of the residual soils and in joints and cracks of the rock. There is a north-south groundwater ridge at the plant area, and groundwater flow is to the north, east, and west. The groundwater gradient in the plant area is about 6 to 7 feet 1.8 to 2.1 m (6 to 7 ft) per 100 feet
