the Dissolution Surface. If the well is to be plugged and abandoned, it will be <br />cemented to surface. If the hole is to be completed as monitor well (hydrologic <br />and subsidence) a steel intermediate casing will be cemented to surface using <br />displacement. Grout adequacy will be verified with a cement bond log. All. well <br />(P&A and monitor) construction will conform to the 2 CCR 402-2 (CO State <br />Office of the Engineer's well construction rules) to eliminate communication <br />between aquifers. No USDW aquifers will be adversely affected by this program. <br />4: The expected time frame for drilling, coring, and P&A/completion for each <br />well is ten to fourteen days, with a total project completion time of approximately <br />three months. This is somewhat dependent on what type of rig (conventional or <br />wireline) is used to drill and core each hole. NSI's priority for this program is <br />core recovery and quality. <br />If further clarification is needed, please contact me, Jerry Daub at (970) 254-1224, or <br />(970) 216-1010. <br />Sincerely, <br />/eraIdZ, PG, CPG <br />President, Daub & Associates, Inc. <br />Cc: Bob Warneke, Natural Soda, Inc.; Executive Director of Manufacturing <br />Paul Daggett, BLM; White River Field Office <br />SPECIALIZING IN PROFESSIONAL GEOLOGICAL, ENVIRONMENTAL, HYDROLOGICAL, GEOTECHNICAL AND PERMITTING SERVICES <br />Page 2 of 3
