In no event may any action based upon any <br />defect in this survey be commenced more than ten years from the date <br />of certification shown hereon. <br />Notes <br />1. Survey datum is based on the supplied information by Eastside Coal Company. <br />2. A descrepancy of 0.2 feet in elevation was found between the two control points. <br />3. Pond volumes have been compared to information developed from a topographical <br />survey done in 1995. The 1995 survey was done to comply with survey standards <br />for a 5 foot topographical map and was not done to the accuracy of the survey <br />shown on this drawing. <br />4. Due to the relaxed standards of the original topograpical survey, the results actually <br />show an increase in the pond volume and it would appear that no silting has taken <br />place. <br />Permit N mber <br />Class .
