The Mancos Gravel Pit is a 110 county permit, approved for 9.9 acres affected area lapproximately 8.2 acres pit area and 1.7 acres access road areal. The pit is located approximately 1.5 miles NE of Mancos, along the west side of county road 42, in portions of the W 1l2 of the SW 1 /4 of Sec. 22, T36N, R13W, NMPM, at 7440' elevation. The operation is active. All Rules referenced within this report are taken from the Construction Material Rules and Regulations of the Colorado Mined Land iieelametion Board, effective 10/95. If the operator does not posses a copy of the current Rules and Regulations, one may be roquested from the DMG office in Denver for 58.00. Mine identification sign was erect and displayed the necessary information. Affected area appeared to be contained within the approved area. One pedmeter marker was located along the north boundary of the permit area. The operator indicated that the lease area was delineated by an existing gas pipeline along the north side and fence lines on the south and west sides. The lease area encloses an area greater than the 9.9 acres approved as the area to be disturbed by this operation. Rule 3.1.1212) requires that the permit area be marked, conditions of the 110 Limited Impact permit require that the total affected area be no greater than 9.9 acres. Additional perimeter markers are necessary as required by Rule 3.1.12121. 3.1.1212) The boundaries of the affected area will be marked by monuments or other markers that are clearly visible and adequate to delineate such boundaries. lel for Limited Impact 1100perations the permit boundary for the purposes oT this Rule shall be considered the effected area; Topsoil had been stockpiled along the north side of the pit area. Vegetative cover on the stockpiled topsoil was sparse and consisted of some grasses and weeds. Despite the lack of protective vegetative cover for the stockpiled topsoil, erosion of the topsoil was not evident. Rules 3.1.9(1) and 131 addresses the establishment of vegetative cover over stockpiled topsoil. 3.1.911) Where it is necessary to remove overburden in order to mine the construction material, topsoil shall be removed and segregated from other spoil. If such topsoil is not replaced on a backfill area within a time short enough to avoid deterioration of the topsoil, vegetative cover or other means shall be employed so that the topsoil is protected from erosion,..., and is in a usable condition for reclamation. 3.1.913) Topsoil stockpiles shall be stored in places and configurations to minimize erosion and located in areas where disturbance by ongoing mining operations will be minimized. Such stockpile areas must be included in the affected areas and subject to all reclamation requirements. The Board may require immediate planting of an annual and/or perennial on topsoil stockpiles for the purpose of stabilization. Weeds were observed on the stockpiled topsoil. Rule 3.1.1016) requires the operator to employ weed control methods. 3.1.1016) Methods of weed control shall be employed for all prohibited noxious weed species, and whenever invasion of a reclaimed area by other weed species seriously threatens the continued development of the desired vegetation. Weed control methods shell also be used whenever the inhabitation of the reclaimed area by weeds threaten further spread of serious weed pasta to nearby areas. 1 & E CoMaet Address ec: Tom Gillis, DMG ^ CE NAME Tim McComb ^ BL OPERATOR MoMSZUma Counri Roed & Bridge ^ FS STREET 1880 North Hwv 146 ^ HW CITY/STATE/ZIP Cortez, CO 81321 ^ HMWMD ICHI ^ SE ^ WOCD ICHI ^ OTHER
