Proposed Project Operational Details <br /> a. Overall Scope: Approximately 25,000 tons of"raw" rock material will be excavated <br /> from the Project Site on a monthly basis, with the excavation reaching a maximum <br /> depth of approximately 80 feet from its existing grade. As rock material is <br /> excavated, the perimeter of the Project Site will have engineered fill with a 3:1 slope <br /> to avoid a sheer drop and facilitate future use should a suitable use be <br /> contemplated. A vegetative buffer will also be provided around the perimeter of the <br /> Project Site. The amount of rock resource within the Project Site is estimated to <br /> provide an active quarry lifetime of approximately 20 to 30 years. <br /> b. Equipment: Excavation of rock will be accomplished through the use of heavy <br /> equipment when possible. If impenetrable rock is encountered during excavation <br /> activities, drilling and blasting will be performed. <br /> c. Material Transport: Extricated "raw" rock material will be temporarily stockpiled <br /> within the Project Site or immediately removed to Applicant's baseyard facilities <br /> located along nearby Railroad Avenue for crushing and processing into finish <br /> 3 Page <br />
