In <br />addition, the amount of flow contributed by Tuttle Draw and Calami� Draw to the <br />San Miguel River is very small (0.4 percent of annual mean flow at Uravan). <br />Therefore, the San Miguel River AVFs are considered to be located outside of the <br />potentially affected area. <br />Xl. Operations on Prime Farmland <br />Based on information presented in soil surveys included in the permit application and <br />the Natural Resources Conservation Service (NRCS) San Miguel Area Soil Survey, as <br />well as correspondence from and consultation with: NRCS staff, the Division has <br />determined that prime farmland soils, which are Prime Farmland when cropped and <br />irrigated . with a dependable water supply, occur in various locations within the NH -2 <br />portion of the New Horizon Permit Area. These prime farmland soils (potential Prime <br />Farmlands) include soil map units D70, D70B, 98E, and'98A, within the.NH -2 portion <br />of the permit area, as delineated on permit Map 2.04.9 -1. <br />The current status of prime farmland soil areas with respect to Prime Farmland <br />designation is as follows: <br />Designated Prime Farmland <br />• Map Unit 98A ( Begay Fine Sandy Loam) which occurs on 3.52 acres in the northwest <br />corner of the NH -2 permit area block was determined to be Prime ' F ' armland, based on <br />NRCS det see NRCS <br />Resource r a e une , m perm tac en 084.9-10-4). <br />Based on the actual areal extent of disturbance and practical considerations the Division <br />has designated a slightly larger (4.68 acre) area incorporating the 98A parcel as Prime <br />Farmland, as indicated on permit Map 2.05.4 -4. r 19, <br />6 CC, r rra v <br />Determined Not To Be Prime Farmland l �cS 6 1 t <br />o.
