' Brian Munson -2- April 2, 1981 <br />3. Haul Road and Access Road Culverts: RC must provide designs and peak flow <br />estimates for all culverts as per Rule 4.03.2(4) or 4.03.3(4) where applicable. <br />Peak flow estimates must include all parameters mentioned in (2)(b)(I) above. <br />4. Fuel Storage Area: A berm or other runoff control practice should be placed <br />around the fuel storage area to prevent contamination. <br />5. Sediment Yield: The note at the bottom of Tab]e 2, page III - 11 is interest- <br />ing to me. Please cite the reference this note refers to. <br />6. Sediment Storage: The Division requires that the sediment storage <br />capacity of a sediment pond be greater than the annual sediment yield. We <br />recommend the storage of at least three years sediment yield. 61e also require that <br />a permanent marker be placed at the sediment cleanout level (preferably at the <br />elevation of the 60% sediment storage volume) in order to assist the operator and <br />inspectors in maintenance scheduling. <br />7. Area 2 and 3 Sediment Ponds: Until reclamation is sufficient for pond removal <br />ponds on disturbed watersheds must continue to meet the present regulations. <br />As such, pond 2 and 3 must have designs submitted which meet the requirements of <br />Rule 4.05.6 as described in (2) above. <br />mob <br />,~ <br />
