PURPOSES The purposes of hydrologic engineering site visits are as follows: 1. Acquaint the reviewer with general site and regional hydrologic character- istics and topography. 2. Confirm the applicant's general appraisal of the site/plant hydrologic interfaces. 3. Review specific hydrologic engineering problem areas with the applicant, his engineers, and his consultants. The site visit objectives will have been achieved if, in addition to viewing pertinent hydrologic features, the reviewer has had the opportunity to discuss specific questions and concerns with the applicant's hydrologic engineers, and is assured that the questions and concerns are understood. In addition, generally acceptable techniques and procedures necessary to respond to staff concerns should be discussed. II. PROCEDURES Questions or items of staff concern are to be developed by the Hydrologic Engineering Section reviewer and discussed in detail with the Section Leader 7-14 days before the scheduled site visit. For any unscheduled site visit (which may be necessary to resolve issues or prepare for hearings), similar questions or items of staff concern should be prepared at least 3 days prior to such site visit and also discussed in detail with the Section Leader. Areas of overlap or interfaces with reviewers in other areas (such as geology, foundation engineering, auxiliary and power conversion systems, mechanical engineering, effluent treatment systems and structural engineering) should be coordinated before questions
