• Define Prime Farmland handling (detailed two lift salvage, storage, and replacement <br />procedures) for areas where soil has not yet been stripped in advance of the pit; address <br />compliance with prime farmland soil handling regulations. Soil handling plan will include <br />clear description of defining characteristics to allow operator to properly segregate top lift <br />from second lift in the field, and to define limit of salvage for the 2"d lift. <br />• Define Prime Farmland handling for areas where mining has previously occurred and are <br />currently either active disturbance or regraded but not yet topsoiled. Operator will identify <br />appropriate Prime Farmland subsoil suitability criteria and provide a plan for sampling of <br />graded spoil (initial 1 sample per 2.5 acre grid) to demonstrate suitability (with NRCS <br />input). Plan will need to meet Prime Farmland handling regulations to the extent possible, <br />given the cun~ent circumstances. For areas where spoil is unsuitable for Prime Farmland <br />subsoil, remediation plan will be developed. <br />• A detailed soil handling plan will also be developed for non-prime farmland soils <br />• A revised soi:i block replacement map will be included in the application, addressing both <br />Prime and non-Prime Farmland soils replacement. Non-Prime soil replacement blocks will <br />be reflective of pre-mine soil conditions and planned postmining use (e.g. Dryland Pasture, <br />Irrigated Pasture, or "Irrigable/Improved" pasture. <br />• Interim Soil Handling for Prime Farmland soil (prior to approval of TR-57) will entail two <br />lift salvage acid segregation of top lift and second lift, as described in the Division's PR-5 <br />Findings Document. The calcic horizon (the distinctive lighter colored subsoil with elevated <br />calcium carbonate) beneath the darker "topsoil", typically defines the top of the 2"d lift for <br />soil salvage. Measures will be taken to avoid or minimize handling of soils under conditions <br />(e.g. frozen or wet surface soil) that would potentially damage soil physical characteristics. <br />Any handling; under such conditions would be limited to pushing top lift and second lift soils <br />into separate windrows to allow necessary room for the next pit cut advance. <br />The Permit Revision. to be submitted some time after the TR will address the broader range of land <br />use and revegetation issues, many of which have been the subject of on-going review for several <br />years, and have been addressed in midterm and technical revision review letters by the Division and <br />also in a comment letter from Jim Boyd of NRCS, and numerous letters from permit area <br />landowners. One of the critical issues will involve the issue of the appropriate ratio of irrigation <br />water shares to acres of land for prudent management of irrigated cropland and irrigated <br />pastureland. There is agreement between Jim Boyd and WFC that, for irrigated alfalfa cropland, <br />between 50 and 60 acres can be irrigated with 50 shares of water (approximately a 1:1 ratio, which <br />would also likely be close to the appropriate ratio for irrigated pastureland). <br />Generally, for areas that were irrigated prior to mining, and where irrigation water is available for <br />irrigation during and after the liability period, the amount of irrigated land should follow this <br />approximate ratio. One exception will likely be the WFC owned parcel which was irrigated prior to <br />acquisition, and which WFC will likely propose to restore to dryland pasture (one +/- 3 acre parcel <br />of Prime Farmland Soil may be need to be irrigated and restored to Prime Farmland Condition, <br />depending on NRCS determination). <br />An approach discus:>ed for lands that may have been irrigated prior to mining, but for which water <br />rights are not available or are insufficient, would be to restore lands to an "improved/irrigable" <br />
