COLORnD0 81212 719-269-1173 FA% 719-2691148 <br />Mr. Jim Stevens RECEIVED <br />Department of Minerals & Geology <br />Department of Natural Resources <br />1313 Sherman Street, Room 215 APR 1 4 '1998 <br />Denver, CO 80203-2273 <br />Re: T.H.E. Aggregate Source <br />Dear Mr. Stevens: <br />I received your letter <br />performed on our storm-water <br />to go over the items one by <br />Division of fulinerafs 8 Geobgy <br />today concerning the inspection you <br />structures and system. I w~~uld like <br />one in this letter. <br />1. The ditch to carry overflow from pond #1 to ponds 5,6 & 7: <br />The ditch was obstructed with two rock piles as you noted. This <br />shouldn't have occurred. I have gotten with the quarry employees <br />and emphasized the importance of keeping this drainage open at all <br />times. Within 5 days of this letter, we will have it c~~mpletely <br />unobstructed and it will remain that way. <br />2. We will conduct a volume survey of ponds 5 and i. If the <br />ponds are not adequate as far as volume is concerned, I will build <br />another pond to meet or exceed the volume requirements. <br />3. Old haul road access: Before we get to your notes on this <br />portion of the storm water plan, I would like to point out that Tom <br />Schreiner and I, on one occasion, and Ken Klco and Tom S~~hreiner, <br />on another occasion, did a walk thru from pond No. 1 i:o Tunnel <br />Drive. Tom Schreiner said this portion of the storm water <br />management was acceptable. I know there is some minor deviation <br />from what is actually built and what is on the drawing - but I feel <br />what we have built accomplishes what we are all after. I am aware <br />there is no culvert at the direct outflow of pond #2, but there is <br />a 36" culvert just 75 feet upstream of pond #2. It seems that two <br />36" culverts within 75 feet is a waste. We will ina•tall the <br />interior rip rap and the concrete block if you insist. There is <br />now such a minimal amount of run off toward Tunnel Drive with the <br />changes made in the pit that I don't believe pond #2 would ever <br />fill, even in a 100 year event. <br />We will rip rap the outfall from the 36" pipe to po:id #3. <br />we will eliminate the terrace at the west end of po.zd #3. <br />
