<br />5. Formation Testing. American Soda has collected <br />sufficient information on the formation in its <br />previously authorized experimental test program. <br />However, during the drilling of new wells the Permittee <br />will be required to submit any pH, specific conductance <br />or other water quality testing data that is collected. <br />This data shall be submitted along with the other <br />completion data prior to issuance of the authorization <br />to inject approval. <br />6, Loaaina Specifications and Coring Programs. During the <br />drilling and completion of the solution mining well(s), <br />a complete suite of appropriate open-hole and <br />cased-hole geophysical well logs and other tests shall <br />be run. This well log suite shall be tailored to <br />provide the data necessary to adequately protect the <br />potential USDWs that will be penetrated by solution <br />mining well(s). The Permittee, utilizing a wireline <br />open-hole logging unit, shall run the following logs <br />through the mining interval, at a minimum, for each <br />well: <br />• Gamma Ray (GR) <br />• Caliper (CAL) <br />• Spontaneous Potential (SP)/Resistivity and, <br />• Cement Bond Log (CBL) shall be run, according <br />to current EPA Guidance found in Appendix D, <br />on the intermediate casing to ensure aquifer <br />protection. If the well design precludes the <br />valid use of a cement bond log, then a cement <br />evaluation tool shall be used; and <br />• within four (4) to six (6) months after <br />initial injection, run a temperature log, <br />noise log or oxygen activation log to ensure <br />that there is no upward movement of fluid <br />behind the casing; see Appendix E for current <br />Guidance. <br />The Permittee shall include appropriate narrative <br />interpretations by a knowledgeable log analyst when <br />submitting this suite of logs and other pertinent logs. <br />Coring may be performed in the mining interval, at <br />approximately 150 to 800 feet below the Dissolution <br />Surface, of solution mining wells as needed to obtain <br />pertinent stratigraphic data for mining planning. Core <br />data shall be provided to the EPA and BLM, if <br />requested. <br />EPA FINAL Area Permit No. C03858-00000 <br />Page 14 of 164 <br />
