C-1981-008 PR-06 PAR 22-Jan-2010 Page 18 of 26 extent of dryland pasture and irrigated pasture depicted on proposed Map 2.05.4-5 is appropriate for the bond liability period (see "a" below). WFC must also demonstrate that the affected lands will be restored to conditions that are capable of supporting the uses which they were capable of supporting before any mining, pursuant to Rule 4.16.1 (see "b" through "e" below). This requirement would apply to lands which may have been infrequently or patchily irrigated prior to mining due to limited irrigation water availability; if the landowner was able to apply some irrigation water to portions of the land prior to mining, the same capability should exist after mining and following bond release. Further clarification is needed as noted below. a) Please provide documentation of NRCS concurrence with the assumptions that are the basis for the acre/share ratio for postmine irrigated pastureland areas seeded with Seedmix #5 (both sideroll irrigation and flood irrigation). Please modify the current acre/share ratio projections if warranted based on NRCS consultation, and revise the postmine acreages of irrigated pastureland and dryland pastureland accordingly. b) For the 38.97 acre Benson property north of BB Road and west of 2700 Road, narrative in sub-section 2.0 of Section 2.05.4(2)(e) states that site grading would be performed so that "irrigation water could be brought to the site in the future, if the owner obtains these rights". Please describe the existing and planned irrigation structures (i.e.) laterals, ditches and pipes, etc. that would accommodate such future use. Please confirm and describe in the narrative how site grading will allow for irrigation of a comparable acreage to the area irrigated prior to mining, if the landowner does choose to irrigate the property at some point after bond release. c) For portions of the Lloyd parcel north of BB Road and west of 2700 Road that were flood irrigated to some extent in the past but would be reclaimed to dryland pasture under the PR-6 proposed plan, please confirm that site grading would allow for irrigation of a similar nature and extent to that performed prior to mining if the landowner chooses to do so after bond release, and describe the irrigation structures that would accommodate such future use. d) For the WFC parcels west of the Lloyd parcel that were flood irrigated to some extent in the past but would be reclaimed to dryland pasture under the PR-6 proposed plan, please confirm that site grading would allow for irrigation of a similar nature and extent to that performed prior to mining if the landowner (or future landowner) chooses to do so after bond release, and describe the irrigation structures that would accommodate such future use. e) For the WFC parcel in the extreme southeast corner of the permit area that was flood irrigated to some extent in the past but would be reclaimed to dryland pasture under the PR-6 proposed plan, please confirm that site grading would allow for irrigation of a similar nature and extent to that performed prior to mining if the
