 "description": "NCDOT is required to include Hazardous Spill Basins on projects based upon the guidelines. The basic requirements for the Basins are the following:\n\nApplicable Locations\nBasins will be provided at stream crossings on highways functionally classified as a rural or urban arterials and, \n\n\n1. The stream (1) is identified as an Outstanding Resource Water (ORW) or a WS-I watersupply, or \n2. The stream (1) crossing is within 1/2 mile of the critical area (2) of a water supply source classified as WS-II, WS-III and WS-IV.  \n\n(1) For the purpose of these guidelines \"stream\" will be defined as those depicted as blue lines on 7-1/2 minute (1:24000 scale) United States Geological Survey (USGS) quadrangles. \n\n(2) Critical area is defined as extending 1/2 mile from the normal pool elevation of a reservoir; or 1/2 mile upstream of , and draining to an intake. This would make the effective area for hazardous spill basins placement, within 1.0 mile of the normal pool or upstream of an intake. \n\nTo Develop a HSB coverages that identifies the potential need for an HSB, the following data sources are identified as needed: \n\nHYAR (24K Hydrography Line - Classified) \nHYARUT (24K Hydrography Line - Unnamed Trib)\nHYPL (24K Hydrography PolyLine - Classified) \nHYPLUT (24K Hydrography PolyLine - Unnamed) \nHQORWDWQ (Includes ORW and WS_I and WS_II WSW)\nWSW (Water Supply Watersheds) \nSWI (Surface Water Intakes) \n\nThis data set contains all finalized stream segments identified as HSB stream line segments.",
