• REVEGETATION PLAN - RULE 2.05.4(2)(e) <br />The Bear Coal Company will comply with all recommendations and <br />suggestions of the Division regarding periodic sampling of the <br />revegetated area to the approved standard. The Bear Coal Company will <br />conduct at the appropriate intervals and utilize proper sampling methods <br />and sampling statistical tests. Unless better techniques are approved <br />in the future, the Bear Coal Company will follow the two recommended <br />guidelines for selecting the proper methods and tests for sampling <br />revegetation areas. These guidelines are "A Survey of Techniques for <br />Measurement of Herbaceous and Shrub Production Covering Diversity on <br />Coal Lands in the West" and "A Statistical Evaluation of Revegetation <br />Success on Coal Lands in the West" (Larson, 1980). The Bear Coal <br />Company will utilize the same sampling measures recommended by the <br />Division for the Bear No. 1 and No. 2 Reclamation Plan. <br />As noted, the area in and around the Bear No. 3 portals has been <br />• previously disturbed. Therefore, the Bear Coal Company will meet the <br />revegetation success criteria of Rule 4.15.10 for previously mined <br />lands. The success standards for ground cover of living plants will be <br />set by recommendation of the Division. <br />The Bear Coal Company will include the Division's recommended revisions <br />of the seed mixture; a revised seed mixture is attached. The following <br />are the revisions to the seed mixture: <br />1. The introduced grasses, Agropyron elongatum (tall wheatgrass), and <br />Bromus hiebarjteinii (meadow brome) will be removed from the mix and <br />replaced by the natives bluebunch wheatgrass (Agropyron spicatum and <br />Agropyron inerme) and mountain brome (Bromus margina~us). <br />2. Yellow sweet clover will be removed from the seed mixture. <br />• 3. Rubber rabbitbush and big sagebrush will be eliminated from the seed <br />mixture. <br />-46- <br />
