Currently the approved route for the pipeline <br /> starts at the CMP manhole near the 6MN Shaft access road where the 5MN water line cross the road. From there <br /> it was routed up along the access road and ran west to the southwest corner of the 6MN pad, from there it was to <br /> follow the Passive Treatment two-track ranch road that is to be used to access the system. The new proposed <br /> route will be a considerably shorter distance and less disturbance. The new proposed route will tie into the <br /> second CMP manhole to the south of the 6MN access road on the 5MN water line. From the existing CMP <br /> manhole the pipeline will be dug in a straight line to the inlet area above the first Wetland cell. This will reduce <br /> the length of new proposed pipeline from approximately 4,850 feet to 2,670 feet. <br /> This submittal includes a revision application form, an exhibit to be placed in Exhibit 49EE and a revised Maps <br /> 23C, 24, & 29 showing the proposed line location. This revision should cause no increase or decrease in the <br /> bond amount and therefore no bond estimate is necessary. We would like to proceed with this project as soon as <br /> possible. We, therefore, appreciate your consideration, cooperation, and assistance in facilitating timely review <br /> and approval of this revision application. After you have opportunity to review the accompanying information, <br /> please feel free to contact me with any questions or to discuss submittal materials or related matters. <br /> Sincerely, <br /> Twentymile Coal, LLC <br /> A"I kjc� <br /> Miranda Kawcak <br /> Environmental Engineer <br />
