Room 215 <br />Denver, C(1 80203 <br />Phone: 13031 866-3567 <br />FAY: (3031872-8106 <br />March 17, 1993 <br />Mr. Mike Ossola <br />County Planner <br />Las Animas County Planning and <br />Land Use Office <br />200 East First Street, Room 104 <br />Trinidad, Colorado 81082 <br />RE: Responses to February 26, 1993 Memorandum, Wyoming Fuel Company <br />(Basin Resources), Golden Eagle Mine, Permit No. C-81-013 <br />Dear Mr. Ossola: <br />Thank you for your office's letter of February 26, 1993, received in our <br />offices on March 1, 1993. We would like to take this opportunity to provide <br />your office with a response. <br />OF'e <br />ti~ 4 <br />Ne %' <br />R~ <br />+d' <br />~ ~9 ]fi <br />Roy Romer <br />Governor <br />Michael B. LOng <br />Drvisian Director <br />Your letter referenced three principal topics with the Golden Eagle Mine <br />permit: permit stipulations, land use issues and mine subsidence issues. The <br />subsidence-related issues have been addressed by the Division in our 1992 <br />Midterm Review of this operation. Please refer to questions 2D and 2E on page <br />8 of the December 1992 Midterm Permit Review. The Division is awaiting the <br />operator's responses to these questions. We will notify your office of the <br />responses we receive. <br />The land use questions raised by your office will be asked of the operator <br />when the Division replies to the operator's responses to our Mid-Term Review. <br />The Division is particularly interested in having the operator update the <br />post-mining land use section of its permit with regard to both the residential <br />development north of Highway 12 and the reclamation of the exhaust fan site. <br />The third topic of your office's letter inquired about mine permit <br />Stipulations 28, 50, 51, 52 and 53. Stipulation No. 28 refers to subsidence <br />monitoring of five adobe houses situated in the vicinity of the mine. This <br />stipulation was incorporated into the mine permit in 1984 because the <br />permittee proposed to mine beneath the Purgatoire River, within the vicinity <br />of these structures, for underground access to the area north of the river. <br />The First North Main was a set of underground tunnels that would have provided <br />access to the area north of the river. However, changes to the operator's <br />mine plans stopped construction of the First North Main, and access to the <br />north side of the river was consequently accomplished via the Third North <br />Main, 9,000 feet to the southeast. Question 2F of the Midterm Review asked <br />for information which will assist us in determining if the adobe structures <br />are within the zone of possible subsidence overlying the Third North Main. <br />The Division will then determine if the adobe structures should have been <br />monitored. <br />
