It allows us to minimize the potential conflict between our D-Portal area traffic and the <br />proposed truck loadout traffic. <br />Typical Cross Sections: I am faxing a portion of Permit Map #67 which shows a typical road section, <br />including the adjacent ditch, which we will use as a basis for our construction of this new road. <br />Modification to Plan Vlew: Included with this letter is a revised Plan Yew which shows these areas <br />more clearly. Topsoil will be stripped to a depth of 6° in all area proposed for disturbance. Topsoil <br />will be stored as shown on the attached Plan Yew with a containment berm surrounding it. <br />Pond: Unfortunatey, the existing pond is not positioned where we would be able to utilize it as a <br />containment structure for the laydown Area. However, we have modified our pond design to sully <br />contain the 25 year event, as suggested, which is 0.06 acre-feet. A copy of the pond/ditch design <br />map and a SEDCAD run for emergency spillway are enclosed. <br />Road Design: The as-built designs for the existing road along the conveyor are shown on Permit <br />Maps #114 and #114A. This road meets all applicable performance standards of Rule 4.0.3.1, and <br />will be adequate for The temporary use we are proposing. The road will be maintained as per the <br />performance standard. Typical sections for the portion of the Haul Road to be used prior to the <br />conveyor road access are shown on Permit Map #67. Performance standards listed in Rule 4.03.1 <br />shall be complied with for the constructon of fhe new road. <br />Suite #305 <br />405 Urban Street <br />lakewood, Colorado 80238 <br />Telephone 303/988-96?6 <br />Telecopier 303/986-8147 <br />
