Environmental Protection Facility Certification <br />Henderson Mine — Permit No. M-1977-342 <br />Technical Revision 23 <br />Ute Park Extraction Wellfield Project —Phase I <br />The Ute Park Extraction Wellfield Project -Phase I was approved as Technical Revision <br />No. 23 to Mine Permit No. M-1977-342 on June 11, 2014. This project is located at <br />Climax Molybdenum Company's Henderson Mill in Grand County. The project involved <br />the construction of an extraction well and support infrastructure, including a pipeline, <br />vault, electrical power line, and instrumentation at a location downgradient from 1 Dam <br />at the Mill. <br />The Henderson Mill and contractors have substantially completed the construction of <br />the project and it has been tested and determined to be functional. The systems were <br />designed and installed to meet applicable electrical codes and Henderson design <br />requirements. <br />Modifications to the initial design have been reflected in the attached Record drawings. <br />One such modification being the field installation of three (3) 37.5kVA transformers, as <br />opposed to the design for three (3) 15kVA transformers. This field modification was <br />approved by the engineer of record for the power pole design. <br />Logical Systems LLC (LSI) was responsible for the design coordination and <br />implementation of the electrical systems. The project was completed in general <br />conformance with the approved design as submitted to the Division of Reclamation, <br />Mining, and Safety.
