It should <br />be noted the USGS datum (NAVD 29) used for this figure is lower by 2.96 feet in this area <br />than the correct datum (NAVD 88). NAVD 88 is used in design in the area as it is considered <br />more reflective of actual ground elevations. NAVD 88 has been utilized for design within the <br />Greeley 35th Avenue Mine. The conversion documentation for the area of the Greeley 35th <br />Avenue Mine is presented in Figure B -3. <br />3.4 Permit Boundary <br />The area involved in the mining operation (permit boundary) and Affected Land is shown on <br />Figure C -1.
