3. The well-completion plans seem to indicate that monitoring wells <br />will be left as open holes in the monitored intervals, rather than <br />equipped with screened intervals. If so, what types of tests will be <br />performed, and what method of sample extraction is proposed? <br />4. For water quality sampling, please submit the proposed sampling <br />and analysis plan, a list of proposed analytes, and a plan for <br />establishing and characterizing pre-operational background water <br />quality. <br />5. The NOI states that water generated during drilling and <br />hydrologic testing will be handled in the same manner as drilling <br />waste. Does this mean that water that does not evaporate is to be <br />transported off site? <br />6. For the drilling and completion of drill holes, please specify how <br />much time is anticipated to "circulate the hole clean"? <br />7. Please specify the composition of the foam used in drilling <br />circulation? <br />8. Please explain the meaning of "short trip any tight spots." <br />9. Well CH-O1 is designated as a Continuous Core and Hydrology <br />Test Hole. The diagram indicates that the hole will be open <br />across an interval of 2,000+ ft. Please specify what kind of <br />hydrology testing will be performed on this hole? <br />10. Please provide additional detail regarding the drill hole plugging <br />and abandonment plan on page 28 of the NOI. Please see the <br />enclosed DRMS plugging and abandonment guide for information. <br />Detail is required for DRMS staff to accurately calculate <br />reclamation costs. <br />If you need additional information, do not hesitate to contact me at the <br />Division of Reclamation, Mining and Safety grand Junction Field Office, <br />101 South 3rd Street, Room 301, Grand Junction, CO 81501, Phone No. <br />970-243-6368. <br />Sincerely, <br />"a, , <br />Steve S.
