suitable growth medium for establishing the grass, shrub, and tree species included in <br /> the proposed revegetation plan. Will the operation perform any test plots and/or soil <br /> testing? If so, please provide details of this plan. <br /> Please be advised, if the applicant is unable to provide demonstration at this time that <br /> the proposed "growth medium"will be sufficient, the reclamation bond will need to <br /> include costs for importing topsoil to the site. In this case, additional information will be <br /> needed, including the estimated volume of topsoil required to reclaim the proposed <br /> maximum disturbance, the anticipated location from which the topsoil will be derived, <br /> and the approximate depth of placement. <br /> Please see the revised language throughout the permit narrative detailing the absence of true <br /> topsoil from the site as well as the Applicant's response to question 20. Quarry highwalls will be <br /> backfilled to a 2.OH:1.OV slope with comingled crushed rock, boulders, and waste fines. <br /> Following tracked equipment compaction, plant growth medium as described in the response to <br /> Division question #15 will be applied at a 6-inch depth to provide substrate for seed germination. <br /> Coarse blasted rock will be used as rock mulch to provide a more hospitable environment for <br /> seed germination and will be placed at a depth of 3-12 inches. Variability in coarse blasted rock <br /> placement is inherent to the variable nature of blasted rock paired with non-regular placement. <br /> Figure 7 details an example of current natural site conditions where coarse rock is comingled <br /> with vegetation on a south facing slope while Figure 6 details a north facing slope with a similar <br /> rocky and volunteer vegetated surface. The latter Figure 6 and slope is an approximately <br /> 1.OH:1.OV fill slope created by the Central City Parkway construction and includes volunteer <br /> vegetation. <br /> Prior to applying plant growth medium and at an appropriate interval, plant growth medium will <br /> be tested by a contract soil scientist to establish if longer-term variations in plant nutrients <br /> develop throughout the quarry's lifetime. Tests will measure both macro- and micro-nutrients <br /> required for plant growth. Pending soil tests, the Young Ranch Resource Quarry may apply <br /> additional amendments to ensure higher vegetative success. The eastern adjacent construction <br /> materials quarry approximately 0.5 miles to the east has experienced successful reclamation by <br /> using only site derived materials. The reclamation plan to be used at the Young Ranch <br /> Resource Quarry is derived, in part, from the adjacent site's proven successful reclamation <br /> methods. Therefore, it is expected that the Young Ranch Resource Quarry will experience <br /> similar reclamation success. <br /> 39. On Page E-2, the application states in the no reservoir reclamation alternative, <br /> approximately 140 acres will be reclaimed as native forest shrubs and tree tubelings, <br /> while approximately 255 acres will be reclaimed with native dry rangeland species. This <br /> adds up to 395 acres, which exceeds the proposed affected area of 335.4 acres. Please <br /> explain this discrepancy. Is the difference in acreage due to additional slopes created <br /> during mining and reclamation? <br /> Discrepancies are now rectified in the permit narrative. <br /> 40. On page E-2, the application states that on-contour single ripping to a minimum depth of <br /> 2 feet will be used at a 10-foot vertical spacing interval on waste rock landform lifts to <br /> divide each lifts final reclaimed slope drainage area by a factor of 5. Please clarify <br /> whether the proposed single shank ripping will be done after each lift is graded to <br /> 2.2H:1 V or after the entire waste rock landform has reached capacity.
