Rifle Gravel Pit#1 July 2023 <br /> • The upland seed mix will be used to stabilize the topsoil piles. This seed mix will be <br /> the same upland seed mix applied to the berms for permanent stabilization, minus <br /> the locally-collected rabbitbrush seed component. Rabbitbrush will not be included in <br /> the stabilization of the topsoil stockpiles, to avoid having to grub woody vegetation <br /> out of the stockpile once it is needed for reclamation. <br /> • Woody vegetation at the site will be removed prior to excavation within the Affected <br /> Lands. Note that woody vegetation is minimal in the proposed Permitted Area. <br /> • Scott will try to ensure that existing vegetation is put to a beneficial use such as <br /> firewood, mulching, lumber, etc. <br /> • The for-sale topsoil and overburden stockpiles will be rehandled as little as possible <br /> until the 60% mining condition is completed. Scott will obtain proper approval from <br /> the Board or Office prior to relocating topsoil and overburden stockpiles, if <br /> necessary. <br /> 6.1.1.3 Revegetation <br /> Figure 14, Exhibit E1 provides detailed information regarding the revegetation of the Rifle <br /> Pit. An excerpt outlining the upland and wetland seeding mixes is included below. <br /> TABLE 1 — UPLAND SEEDING AND PLANTING MIX <br /> % COMMON NAME SCIENTIFIC NAME VARIETY FORM PLS (LBS/ACRE)* <br /> 15 ORCHARD GRASS DACTYUS GLOMERATA AS LOCALLY AVAILABLE BUNCH 2.7 <br /> 15 WESTERN WHEATGRASS PASCOPYRUM SMITHII AS LOCALLY AVAILABLE SOD—FORMING 2.7 <br /> 15 TIMOTHY PHLEUM PRATENSE AS LOCALLY AVAILABLE BUNCH 2.7 <br /> 40 MEADOW BROME BROMUS BIEBERSTEINII AS LOCALLY AVAILABLE BUNCH 7.2 <br /> 15 INTERMEDIATE WHEATGRASS THINOPYRUM INTERMEDAM AS LOCALLY AVAILABLE BUNCH 2.7 <br /> — RUBBER RABBITBRUSH ERICAMERIA NAUSEOSA WILDLAND COLLECTED SEED BUNCH 0.05 <br /> TABLE 2 — WETLAND SEEDING AND PLANTING MIX <br /> % COMMON NAME SCIENTIFIC NAME VARIETY (AS AVAILABLE) FORM PLS (LBS/ACRE)* <br /> -- SPEARLEAF RABBITBRUSH ERICAMERIA UNIFODUS WILDLAND COLLECTED SEED SHRUB 0.05 <br /> -- COYOTE WILLOW SAUX EXIGUA CONTAINERIZED STOCK (60 INS) SHRUB 1 CONTAINER (60 III) <br /> PER 5 SQ.FT. <br /> -- BALTIC RUSH JUNCUS BALTICUS AS LOCALLY AVAILABLE SOD—FORMING 0.6 <br /> -- NEBRASKA SEDGE CAREX NEBRASCENSIS AS LOCALLY AVAILABLE SOD—FORMING 1.6 <br /> -- BEAKED SEDGE CAREX ULTRICULATA CONTAINERIZED STOCK (10 INs) RHIZOMATOUS 1 CONTAINER (10 IN3) <br /> PER 3 SQ.

FT. <br /> The proposed revegetation was selected with the following intents: <br /> • Establish a diverse, effective, and long-lasting vegetative cover that is capable of <br /> self-regeneration without continued dependence on irrigation, soil amendments or <br /> fertilizer. Native mixes were selected to comply with NRCS standards, and to match <br /> surrounding land conditions. <br /> • Provide for the greatest probability of success in plant establishment and vegetation <br /> development by considering environmental factors such as seasonal patterns of <br /> precipitation, temperature, and wind; soil texture and fertility; slope stability; and <br /> direction of slope faces. Similar attention was given to biological factors. <br /> • Ensure the establishment of a diverse and long-lasting vegetative cover by <br /> employing site preparation and protection techniques such as soil conditioning; <br /> mulching; and soil amendments. <br /> 38 <br />
