URANIUM LEASING SITES <br />Reseeding Specifications <br />The following seed mixture was developed, in consultation with U.S. Bureau of Land Management, and is <br />generally approved for use within the Slick Rock, Naturita, Uravan, and Gateway, Colorado, areas. Seed <br />selection criteria were based on climate and elevation ranges within these areas. Recognizing that surface <br />soil conditions, nutrients, and available moisture can vary within these areas, successful establishment of <br />six or more of the twelve species is considered adequate. If the total number of species seeded is less than <br />that specified below, the seeding rates for the individual species must be adjusted accordingly. All seed <br />tags must be submitted to DOE for verification prior to the seeding application. <br />S ecies Broadcast <br /> Application <br />Scientific Name Conunon Name Rate <br /> - lbs.

If seed is drilled, use one-half (1/2) the broadcast rate. <br />Seeding shall be performed during one of the following time periods: <br />$ For best results, between October 15 and consistent ground freeze; or <br />$ Between August 1 and August 31. <br />Revegetation efforts on the disturbed areas will be considered satisfactory when: <br />$ Soil erosion resulting from the operation has been stabilized; and <br />$ A vegetative cover at least equal to that present prior to the disturbance and a plant species composition <br />at least as desirable as that present prior to the disturbance has been established.
