~, iii iiiiiiiiniii iii <br />Mr. Nathan Moore <br />Environmental Protection Specialist <br />Permits Unit <br />Water Quality Control Division <br />4300 Cherry Creek Drive South <br />Denver, Colorado 80246-1530 <br />Dear Mr. Moores <br />.• <br />March 5, 1999 <br />RECEIVED <br />MAR 0 8 1999 <br />Division of Minerals & Geology <br />I have called your office and left a callback number but <br />haven't received a callback. <br />After reading your fact sheet I believe I do not need a storm- <br />water discharge permit. <br />I am enclosing a stack of papers from the Soil Conservation <br />Service, and I refer you to the Physical Properties of Soils, <br />you will note under Permeability the 0 to 3 inch zone accepts <br />water at the rate of 2 to 6 inches per hour (high:) <br />However once the top three inches is removed then the perme- <br />ability increases to 6 to .20 inches per hour. <br />This proves to me that all water falling on the pit area will <br />immediately percolate into the sand and later will reach the <br />Arkansas River one mile away in a very clear and unmuddied <br />condition. <br />If in the future we uncover some rocky or clay structure -- <br />we will then have to reassess the situation and construct a <br />holding pond to clean the runoff and obtain a stormwater permit. <br />If this seems unreasonable to you let me know and I will be <br />glad to spend time with your fieldman and to hear what he has <br />to say about the pit area. <br />No processing water will be used on site. <br />Sincerely <br />`Copy to Tony Waldron <br />MLR B <br />P/ 0.
