A site inspection was made of the Thornburg Pit as part of the Division's 4-year <br />inspection program. .The Thornburg Pit is located 1.5 miles northeast of Bennett. Present <br />during the inspection was Stanley Thornburg. <br />2. The Thornburg Pit is permitted for a total disturbance of 106.747 acres. Alluviual dry <br />mining methods are employed. The operator has posted a financial warranty of $14,000 in <br />the form of a Corporate Surety. The post-mining land use is cropland. Approximately 65.6 <br />acres will be seeded to alfalfa and 21.0 acres will be seeded with native rangeland <br />grasses. <br />3. Signs and markers were posted as required by Rule 3.1.12. <br />4. The Thornburg Pit is currently active with all disturbance occuring within the permit area <br />and in accordance with the approved mine plan. A majority of Area 1 is currently <br />disturbed. Approximately 50$ of disturbed slopes have been graded to a configuration of <br />3:1. The remaining disturbed slopes have not yet been graded to reclamation contours. The <br />operator has done a good job of salvaging available topsoil. <br />5. This inspector estimates the current reclamation liability to include $1,000 worth of <br />finish grading work, respreading several thousand cubic yards of available topsoil and <br />revegetation of the Area 1. The existing financial warranty is adequate to cover these <br />costs. <br />6. Mr. Thornburn expressed an interest in reducing the permitted aceage by 3-5 acres in the <br />eastern portion of the permit area. This area was inspected and found~to be undisturbed by <br />mining. Mr. Thornburg is encouraged to apply for an acreage reduction or a financial <br />warranty release for the acreage in question in conformance with the requirements of Rule <br />4.16 (see attached copy). At a minimum, the request should include a description of the area <br />and acreage involved and a mining plan map showing the specific area or area(s) to be <br />released from further reclamation responsibility. <br />I & E Contact Address <br /> ^ CE <br />NAME Mr. Stanley Thornburn ^ BL <br />OPERATOR Thornburn Family Limited Partnership ^ FS <br />STREET 50747 E. 38`° Avenue ^ HW <br />CITY/STATE/ZIP Bennett, CO 70102 ^ HMWMD (CH) <br /> ^ SE <br />cc: Carl Mount, DMG ^ WQCD (CH) <br />Attachment <br />
