Mr. Mac Shafer <br />October 15, 2012 <br />Page 2 <br />1) Once these roads are in place, Transit Mix must submit a TR (Technical Revision) to <br />incorporate new facilities map showing the location and the size (width and length) of each <br />road. This will allow the Division to re- calculate the cost to reclaim these added <br />disturbances. Please acknowledge and commit to submitting this revised facilities map <br />once the roads are in place. <br />Under Explosives use and Proof of Surrounding Stability, the operator states, "Explosives will be <br />required to reclaim the Pikeview Quarry ". The operator further states, "It is anticipated that the <br />advance of blasting operations may aid in helping to stabilize the landslide areas currently creeping <br />on the Pikeview property. However, the applicant does not anticipate any stability issues in lands <br />surrounding the Pikeview Quarry, nor any impacts outside of the permit boundary." <br />2) In order to make sure no structures outside of the permit area are affected by the planned <br />blasting, the operator must submit a revised blasting plan in accordance with Rule 6.5(4) of <br />the Construction Materials Rules and Regulations. <br />6.4.5 Exhibit E- Reclamation Plan <br />Under the reclamation plan, the operator states, "Inert concrete fill from removal of building <br />foundations may be accepted for disposal in the pit. Each load accepted for disposal will include <br />documentation that it is asbestos free, and records of the volume of the materials and their <br />certification will be retained at the quarry office for a period of three years ". <br />1) Please submit the notice required by Rule 3.1.5(9). The notice must include: <br />a. A narrative that describes the approximate location of the proposed activity; <br />b. The approximate volume of inert material to be backfilled; <br />c. A signed affidavit certifying that the material is clean and inert, as defined in Rule <br />1.1(20); <br />d. The approximate dates the proposed activity will commence and end; <br />e. An explanation of how the backfilled site will result in a post- mining configuration that <br />is compatible with the approved post- mining land use; and <br />f. A general engineering plan stating how the material will be placed and stabilized in a <br />manner to avoid unacceptable settling and voids. <br />g. Please provide the location or locations of the source of the inert fill material so the <br />reclamation warranty can be adjusted accordingly. <br />2) Please respond to the concerns regarding the proposed reclamation plan for the quarry and <br />importation of inert fill to accomplish the task, attached as part of Exhibit 6.5, memo to <br />Berhan from T.0 Wait. Her comments include the grading plan as inflection points that <br />would need to be addressed to establish a stable reclamation plan. It requires the operator <br />to provide a detailed reclamation plan that will achieve a stable post mining slopes. <br />The operator states, "Some additional measures have been taken and designed into the mining and <br />reclamation plan to prevent the final reclaimed slope from being saturated. Surface runoff from the <br />hills above the disturbed areas will be diverted around the stabilized and reclaimed slopes. In <br />addition a series of French Drains will be installed across the current mine road connecting the <br />mine office to the aggregate plant area ". <br />2 <br />
