Classifications for each river basin so that interested 5 1 will be able to easily determine the appropriate critical area. boundary limits along streams and rivers. The schedule of Classifications are based on hydrographic data depicted on U.S. Geological Survey (USGS) 1:24,000 (7.5 minute) topographic maps. It should be noted that local governments will be responsible for delineating the outer boundary limits of their critical areas. Since they may utilize land marks, roads, property boundaries or other features in this delineation, there could be a slight difference between the stream segment description and the delineation on land. . In the water supply protection rules local governments may choose to extend their critical or protected area boundaries beyond the state minimum limits. Proposed classifications and maps have been developed based on the minimum requirements established in the adopted rules. where local governments choose to modify or extend these boundaries, DEM should be advised of the intended changes so that the proposed boundaries can be reviewed and records made consistent as appropriate. This is especially important where local governments choose to extend their critical or protected area boundaries. Local government should provide copies of the appropriate USGS 7.5 minute quad maps to DEM indicating any modifications of the boundaries. In some cases local governments have indicated that waters currently classified for water supply areas are no longer being used and there are no plans for future water supply use of these waters. Thus these waters are being proposed to'be reclassified to a classification other than for water supply use. If there are other areas where waters are no longer being used for water supply Purposes and there are no plans for future use, comments should be provided by the local governments who have land use authority around these waters during the hearing process so that these areas can be reclassified in a similar manner. It should be noted that all reclassifications must be approved by the U.S. Environmental Protection Agency (EPA). In other cases waters that are not currently classified for water supply use but are part of a water supply watershed or protected area are proposed to be reclassified as water supply waters. There are some instances where waters flowing into other states from North - Carolina are currently classified as water supply waters. These classifications were based on downstream uses or standards in the other states involved. Retaining these areas as water supply waters would require that local governments impose land use controls and protection ordinances to protect these waters. At this time it is proposed that these areas be reclassified to a classification other that water supply. Local governments in North Carolina would not be required to adopt water supply protection ordinances for these waters. In developing the proposed classifications, information on existing wastewater discharges and existing land use-practices was evaluated to determine the most appropriate proposed classification 5
