51 Interior Dec. 286 <br />Cite as: 151 Interior Dec. 286, *291, 2000 WL 1740340, **4 (D.O.2.)) <br />Page 5 <br />field Office (AFO), OSM, informed DMG that *291 it considered its response to <br />violations 1 and 3 to be "appropriate," but the response to Violation 2 to be <br />inappropriate. AFO explained, regarding Violation 2, that the facts alleged by <br />he Tatums, if true, would constitute a violation of the State program and that <br />~he DMG was obligated to conduct a more thorough investigation. On the same <br />date, OSM also informed the Tatums of the results of its review of DMG's <br />esponse. <br />By letter dated February 14, 1994, DMG sought informal review of AFO's <br />etermination regarding Violation 2, in accordance with the procedures set forth <br />n 30 C.F.R. § 842.11(b)(1)(iii), asserting that the inappropriate finding <br />~hould be reversed because its investigation into the technical aspects of the <br />lleged violation was ongoing. On May 26, 1994, the Deputy Director, OSM, <br />responded to DMG's request for informal review by granting it an additional 60 <br />~ays in which to complete its investigation. <br />By letter dated July 18, 1994, DMG informed AFO that it had completed its <br />investigation and that, based on a letter from Jim Tatum stating that it <br />~ppeared that an airshaft constructed by BRI had not harmed the water well, it <br />elieved the issue had been resolved. It requested that OSM find its response to <br />Violation 2 to be appropriate. AFO forwarded this information to the Deputy <br />erector, OSM, by memorandum dated July 29, 1994, stating "AFO does not believe <br />hat DMG's investigation answers the question whether or not the mine shaft has <br />impacted the water well." <br />**5 By letter dated December 2, 1994, the Tatums requested informal review, <br />ursuant to 30 C.F.R. § 842.15(a), of that part of the AFO's February 1994 <br />ecision relating to Violations 1 and 3. The Deputy Director, OSM, acknowledged <br />this request in a January 18, 1995, "interim response," wherein he also stated <br />hat his response would serve as "an update regarding our pending decision to <br />Colorado Division of Minerals and Geology's (DMG) request for informal review of <br />Part [Violation] 2 of the same TDN." He informed the Tatums that "the Colorado <br />bMG has made a firm commitment to promptly take the lead in conducting a <br />_horough technical investigation to determine whether Basin Resource's <br />underground mining operations have impacted the water level in your well and <br />lave caused subsidence-related damage to your property." He stated that upon <br />4ompletion of DMG's technical investigation and review of subsequent actions <br />taken by DMG, OSM would notify them of its decision on the violations. <br />On February 1, 1995, DMG and OSM officials, the Tatums, their mining engineer <br />consultant, and representatives of BRI all visited the Tatums' house to conduct <br />an investigation of the subsidence allegation. In his February 8, 1995, report <br />~f that investigation, DMG official, Jim Pendleton, an engineering geologist, <br />Mated at page 4 that there was "sufficient evidence to conclude that mine <br />subsidence is not the cause of the Tatum residence's observed structural <br />symptoms." In part, he based *292 that conclusion on his observations of the <br />foundation of the house. He stated at page 3 of his report: <br />I entered the crawl space beneath the main floor from the partial basement. <br />* * * I examined the crawl space foundation walls by flashlight * * *. The <br />foundation consists of field rock and mortar walls founded in excavated <br />drench[e]s. Two to three courses of unfinished adobe blocks are placed on top of <br />the field stone wall as a leveling course. Finally, wooden blocks support the <br />Copt. ® West 2001 No Claim to Orig.
