The criterias for access road certification are stated in Section 4.03.2 of the Regulations <br />of the Colorado Mined Land Reclamation Board for Coal Mining. All required criterias were met for this <br />road. There are no side slopes steeper than I.SH:IV. The road has an average grade of ten percent with a <br />small 70 foot section at I I percent grade. The water control system for the road was designed to safely <br />pass the peak runoff from a 10 year 24 hour precipitation event. <br />If you have any questions, please give me a call. <br />Sincerely yours, ~,qQ ftr;>~ <br />RD <br />H <br />A <br />INC <br />LAWSO <br />N <br />AS <br />SO <br />C <br />IATES ; ~F.\ F'' f=. ^• ~~ <br />~ <br />~ <br />~ <br />~ <br />~ <br />Q <br />~ <br />~ <br />~ <br /> <br />Charles C.
