<br />-g - <br />2. As with the post-construction revegetation plan the applicant needs to <br />expand the discussion of the post-mining revegetation plan to address the <br />revegetation seed mix, mulching rates, fertilization rates, and grazing <br />management plans. <br />3. The applicant needs to propose a revegetation monitoring program <br />consistent with requirements of the regulations. <br />4. Storm King proposes to establish research plots at the refuse disposal <br />area in order to determine whether revegetation success standards can be met <br />with less than four feet of cover. A complete set of plans must be submitted <br />to the Division. These plans must include, at a minimum, a description of the <br />treatments, location of the plots on a map, a discussion of the design <br />statitics, a discussion on monitoring, and a discussion of statistical <br />comparison with the appropriate revegetation success standard. <br />Protection of Public Parks and Historic Places -Rule 2.05.6(4) <br />On page 4-gl of the permit application is a discussion of a parcel of land <br />whose intended use appears to be a public park. Is this the same parcel <br />denoted as "Park land" on Figure 3.1-1 and belonging to Garfield County <br />Commissioners on Figure 2.1-4? If so a reference to either of these maps <br />should be added to the narrative on page 4-91. <br />Subsidence - 2.05.6(6 <br />The application includes a narrative discussion of subsidence-related concerns <br />within section 4.5.5, and a technical projection of the anticipated subsidence <br />due to the proposed permit's mining activities within appendix 4.5-1. Review <br />of these materials has determined several inadequacies. <br />The technical projection of subsidence made within the application theorizes a <br />mechanism which limits subsidence generation to gob formation on a panel by <br />panel basis. No consideration is given to potential stoping of gob materials <br />downdip into subsequently lower panel levels. If such stoping were to occur, <br />projected subsidence magnitudes may be increased. Considerable elaboration <br />upon the anticipated mechanism of subsidence will be necessary before the <br />application can be considered adequate. <br />
