2.C5.~ ~ ~ SUBS1DIrNCE SURVEY MONITORING AND CON'T'ROL PLAN <br />• An investigation of the surface of the entire existing and proposed permit areas and the adjacent <br />area has shown that there are no buildings, pipelines, powerlincs, ditches or other structures <br />which require protection. <br />Also, no renewable resource lands were found within the permit area. The water•beariltg strata <br />of the Raton and Vcrmcjo Formations which overlie the coal are not renewable resource lands <br />because [hey arc not truly aquifers. They supply an insignificant, if any, quantity of water to <br />the sttrrottnding area. Quality is generally poor, and the hydrologic properties of the strata are <br />also poor, <br />Surface land use on the existing and proposed permit areas is rangeland, which is trot a <br />renewable resource laltd. <br />`L'he only structure of any significance in the proposed subsidence am is the South Starkville <br />Gulch drainage. It is an ephemeral drainage south of the existing mine workings. No :tdvattce <br />or retreat mining took place near the drainage during the initial permit term. <br />!f any full extraction occurs below the drainage in the tlpmming permit term, the stream <br />channel will be visually surveyed to determine if any significant and detrimental profile changes <br />occurred. <br />A eleseription of all structures within and adjacent to the permit boundary is included in Section <br />2.05.3(3) of this permit application. "I'he lou~tions of the structures are shown on Map 13, <br />• Surface Facilities. Most of the facilities have been removed. The facilities which will remain are <br />listed in Section 2.05.4 of the permit application. No undcrgroultd activities have occurred <br />under the facilities which will remain, therefore, under worst possible subsidence conditions, no <br />material damage is anticipated. <br />Li the backfill area, however, the backfill material is underlain by the backEilled Mine No. 2 <br />portals. Given that actual mine development occurred some distance from the portal area and <br />the direct support provided by the portal seals and backfill, no significant settlement which <br />could impact the backfill is anticipated. <br />P.itMC will conduct periodic visual inspections for any subsidence related impacts. If any <br />subsidence related impacts are observed, EFMC will take immediate steps to repair any areas of <br />concern. <br />n <br />~ I <br />~::~v<7aKUSrv~scn'ra7t.
