They are <br />divided into four general categories: <br />• Sites in the North Fork Drainage basin issuing from the strata above the F-Coal Seam. <br />• Sites in the North Fork Drainage basin issuing from the strata below the F-Coal Seam. <br />• Sites in the Jumbo Mountain area in the North Fork Drainage issuing from strata above the <br />B-Coal Seam. <br />• Sites in the Dry Fork Drainage issuing from strata above the E-Coal Seam. <br />The spring and seep monitoring system remains the same as in WY2001. The locations of the <br />monitoring sites are shown on Map 2. A summary of the spring and seep monitoring is presented <br />in Table 3. <br />n <br />LJ <br />8 <br />Project # 00301 HydroGeo, Inc. <br />
