Air Quality <br />Air quality control wasaccomplished by sprinkling all road, or other affected areas from <br />which fugitive dust will occur with water or hard-surfaced. There wereno stack <br />emissions from coal burning; and coal conveyor, washer plants and crushers were <br />covered and/orwetted to prevent coal dust and/or fines from being emitted into the air. <br />Refer to 2.05.6, Mitigation of the Impacts. <br />2.05.5 Post-Mining Land Uses <br />Oakridge Energy returnedthe disturbed areas at the Carbon Junction Mine to post-mining <br />land uses consistent with the existing and planned uses of the landowners. The proposed <br />post-mining land uses are industrial and commercial, recreation, and residential. During <br />the initial permitting of the Carbon Junction Mine, the Ewing Mesa area was relatively <br />undeveloped and generally outside the area adjacent to the city of Durango thought <br />logical for development. With the large influx of new residents in the early 1990's, <br />development of Durango and mid-La PlataCounty has increased greatly, making <br />development of Ewing Mesa property a realistic and economically feasible endeavor. <br />The need for construction materials fueled the development of the current Ewing Pit <br />(sand and gravel extraction) within the Carbon Junction Mine permit boundaries. The <br />sale of Ewing Mesa property which was formerly in dryland farming, or undeveloped, <br />has resulted in residential development, establishment of an equestrian center, and the <br />development of a golf course. As evidenced by these developments, the current land uses <br />of property within and adjacent to the Carbon Junction Mine have significantly changed <br />since initial mine permitting in 1982. <br />With the recognition of the changes in adjacent land uses, Oakridge Energy modified the <br />proposed post-mining land uses for the Carbon Junction Mine permit area in 1996 to <br />reflect the reality that reclamation of the Carbon Junction Mine will be ultimately <br />directed toward serving these "new" land uses. The present disturbance at the mine will <br />bereclaimed at the conclusion of mining to the standards presented in this approved <br />permit. To the extent that approved reclamation activities will hinder implementation of <br />the post-mining land uses, Oakridge Energy will seek approval from CDRMSto modify <br />the reclamation plan to conform to the approved post-mining land uses. <br />The change in the approved post-mining land uses did not necessitate significant changes <br />in the reclamation plan measures proposed. No changes to backfilling, grading, <br />retopsoiling or revegetation measures were proposed from the original reclamation plan. <br />The single significant change was in the revegetation success criteria, wherein the <br />appropriate criteria of vegetation cover sufficient to control erosion was employed. <br />Should theplanned development not take place, no on-the-ground modifications to the <br />existing reclamation plan are anticipated to be necessary. <br />Rule 4.16.3 addresses performance standard requirements where alternative land use <br />designations have been requested. These requirements are addressed below. <br />Abridged Permit Document 5-16 Permit Renewal RN04 4/2014 <br />
