be necessary and appropriate to promote slope stabilization and enhance safe passage for wildlife
traveling through the reclaimed quazry area in the future.
The first 12 inches of soil consists of very stony loamy fine sand (see Exhibit B ). Because this
material is primazity rock and sand, it does not support significant vegetation. The intended future
use for the area is rangeland, which wilt be reestablished by revegetating with amix ofnative grasses
in a manner and amount specified by Boulder County in the Revegetation and Native Grasses
Publications included in Exhibit D, and by reestablishing native Ponderosa Pine @ ten trees per acre
and Rocky Mountain Juniper shrubs @ five per acre.
Environmenfal Impacts
The current condition of the area of the property proposed for quarrying includes an historic quarry
that was abandoned more than fifty years ago. When the historic quarry was developed, many of the
reclamation and revegetation standazds that now regulate 110 projects and that are now governed by
the State of Colorado's Mined Land Reclamation statute did not exist. The demand for Lyons Red
Sandstone as a construction material throughout the Front Range and elsewhere in the United States
continues to exist Modem mining and reclamation techniques will restore the site effectively to a
natural condition and eventually reclaim the site, including the unreclaimed quarry found in TBS 2.
See T-Bone Stone Mining Plan Map.
The T-Bone Stone Site Plan illustrates how this wilt be accomplished The proposed mining and
reclamation plan will result in improved erosion control in areas of the site that aze too steep for
permanent reclamation today. Regrading of the quarry will actor on an ongoing basis during the
quarry's productive period, which is estimated to be fifty (50) years or more. Revegetation (with
drought taterani seed in accordance with County regulations and recattunendations) of the areas
within the State of Colorado § 110 permit areas, will commence after final grade is reached and the
stone deposits have been removed.
T-Bone Stone's reclamation plan will use waste rock and stockpiled overburden to complete the
property's restoration. The quarry will be left in a condition that will continue to provide important
connections for wildlife in the area, and it will serve important buffering functions for habitat,
wetlands or riparian areas.
Boulder County Limited Impact Specla! Review Permit Not Required
Boulder County Land Use Code §4-508 (A), def nes "Limited Impact Open Mining" as follows: "the
extraction of earth materials by mining directly from the exposed deposits or other materials where
mining operatians affect less than Yen acres of land within a parcel. T-Bone Stone is applying for a
Colorado I 10 permit, which is limited to tea acres. The exception provision, §4-508 (A) (5} (ii),
provides that a quarry which "extracts less than 3,600 tons per year" is not required to go through
the LISR process.
