Response: Castle has been backfilling the quarry for several years as part of its reclamation <br /> commitment, and this will continue. Castle intends to accelerate the backfilling and grading to reclaim <br /> the site in the timeline specified in Exhibit D. <br /> The new disturbance areas vary from Amendment 3 to Amendment 4. <br /> Response:The two amendments have different designs, and the reduced excavation of granite at the <br /> western extent of the quarry reduces the area of new disturbance. This also reduces the extent of <br /> highwalls that will remain. <br /> There is not enough topsoil onsite, and there are limited details on importing topsoil. <br /> Response:The permit application has been revised to include details on topsoil volumes available <br /> onsite,topsoil importing, and generating growth medium for use as topsoil.The costs for generating <br /> growth medium have been included in Exhibit L.

These <br /> sources and methods are standard for calculating construction costs in the mining industry. <br /> The water information is difficult to understand. <br /> Response:The maps included in Exhibit G have been revised to be more legible. <br /> Mount Comments <br /> 1.
