Each time, we make a set of measurements <br />from the same exact survey control points to the same <br />exact points on the pipeline. Throughout the <br />monitoring process, we have found the pipeline to be <br />in substantially the same position, exhibiting no <br />movement. <br />We are using a Topton Total Station Land <br />Surveying instrument, shooting to a reflector prism <br />mounted on a range pole. Our measurements are shown <br />in the attached chart. This chart shows the variation <br />in horizontal position (by coordinate) and in <br />vertical position (by elevation). The variations run <br />from 0.00 feet to 0.08 feet (about 1 inch), which ie <br />the expected variation in accuracy due to the <br />equipment and procedures being used. <br />Sincerely, <br />BAY <br />
