2.0 REVEGETATION PLAN <br />2.1 GENERAL REQUIREMENTS (RULE 4.15.1) <br />The mine has been in existence since 1901, with continual modification since that time until <br />final closure in 2014. With significant areas of the mine disturbed prior to the enactment of <br />reclamation laws, multiple private and public surface landowners, and multiple post -mining <br />land uses, the revegetation plan and revegetation success criteria are necessarily complex. <br />The reclamation plan has been revised (2019) to reflect the complexity of the pre- and post- <br />SMCRA regulatory requirements and the requirements of the post -mining land uses and <br />surface landowners. <br />2.2 SCHEDULE OF REVEGETATION (RULES 2.05.4.2(E), 4.15.3(1)) <br />Revegetation will be undertaken as soon as practicable during the revegetation window <br />specified below after regrading and replacement of soil growth medium. <br />2.3 SEED MIXES, SEEDING & PLANTING AND USE OF SPECIES <br />(RULES 2.05.4.2(E), 4.15.2, 3) <br />2.3.1 SEED MIXTURES <br />Several seed mixes have been and will be employed at the mine site, depending upon the post <br />mining land use and surface ownership of the area to be revegetated. <br />For areas where the surface owner is OMLLC or Hotchkiss Ranches, and the post -mining <br />land use is undeveloped land, a seed mix designed to compliment the post mining land use <br />will be employed (Table 3). Disturbances on lands where the surface owner is the BLM or <br />Forest Service and the post -mining land use is undeveloped land, disturbances will be <br />revegetated with the seed mix specified by the management agency (Tables 4 and 5). <br />The seed mix for the private surface holdings was developed by selecting species similar to <br />the major species components (dominant diversity, seasonality and growth form) found in <br />the predominant range sites correlated with the underlying soil communities. <br />Seeding rates are expressed in pounds of Pure Live Seed (PLS) per acre and are specified at a <br />rate of approximately 35 live seeds per square foot for drill seeding applications. <br />2.3.2 OTHER PLANT MATERIALS <br />OMLLC does not propose to employ seedlings or other live plant material in revegetation <br />efforts at the mine site. <br />TR -77 H-3 Revised March 2019 <br />
