Add an Affected Land Boundary symbol to the appropriate Exhibit C legend and use it on the map/s to identify positively land that will be affected (see definition of affected land Rule 1.1(3) as opposed to land that will not be affected. The Division recommends that you be liberal in identifying affected lands. Disturbing land outside an affected land boundary could be considered a possible violation of the permit. Exhibit D -Mining Plan Item No. 12 This item asked Holcim to provide a plan to prevent damage to the natural gas pipeline running through extraction cuts 13, 14, 16 and 18. Your response plan is to negotiate with El Paso - Colorado Interstate Gas Company to relocate the gas line to another area, where it will not be impacted by blasting and other quarrying activities and, if Holcim will be mining at a distance that is less than 500 feet to the natural gas pipeline, seismic monitors will be installed. A letter to the Division dated May 12, 2003 from the gas company states "CIG requests that we be notified when the 500 feet sepazation comes into effect. The peak velocity caused by the detonation of explosive charges should not exceed 4 inches per second within 500 feet of the pipelines." In a letter to the Division dated June 11, 2003 Michael B Toelle, Interim Quarry Manager, states " Holcim will notify the CIG when blasting comes within 500 feet of the natural gas pipelines and will insure that peak velocities will not exceed 4 inches per second within 500 feet of the pipelines." Please re-state this commitment by Holcim as further response. It will serve for the record as Holcim's official response to this adequacy item. Exhibit E -Reclamation Plan Item No. 13 Your response to this item is a revised Exhibit E. On the first page, Table 1 is a list of "Affected and Reclaimed Areas". In the box titled Mining Areas, Cut 1 is shown to be 28 acres whereas in the box titled Reclamation Areas Cut 1 is shown to be 137 acres, a difference of 109 acres. Please correct the figures or explain the appazent discrepancy. On the same table, It appears that the difference of 73 acres between Mining Areas 19-22 and Reclamation Areas 19-22 is the previously mined (under this permit) area east of the planned mining cuts. Please confirm this assumption or provide a correct explanation.
