67'i 'i <br /> THE GENERAL HYDROLOGY OF THE SUBJECT SITE <br /> 1. The disturbed area which amounts to approximately 12 acres at the present <br /> time drains into our pit which is then pumped into our large settling <br /> pond. <br /> 2. The volume of water being handled by our "closed circuit" water system <br /> amounts to our annual rainfall plus a small amount of underground spring <br /> water encountered by the digging of our pit. This water is pumped into <br /> our large settling pond at an estimated annual rate of 150,000 gallons <br /> per day. A greater amount of water is pumped from this settling pond <br /> into our plant both as dust control device and a stone washing device. <br /> A portion of this water is returned to our settling system via our <br /> small settling pond. The render is added to our stone as moisture <br /> content or it evaporates. <br /> 3. The small settling pond has a holding capacity of approximately 1,000,000 <br /> gallons and the large pond has a capacity of approximately 8,000,000 gallons. <br /> If in the future we need to increase our holding capacity, we can add an <br /> additional 4,000,000 gallons by adding three (3) feet of additional embanks-- <br /> meat along the eastern bank of the large settling pond (3' x 4 acres 20,00'' <br /> cubic yards or 4,000,000 gallons). <br /> 4. 411 of the remaining undisturbed areas that drain into Phil's Creek are <br /> either stabilized with crushed stone or vegetation. <br /> ✓ In addition to the performance standards covered by the ordinance we <br /> propose to carry out the following policies in regard to sedimentation and <br /> erosion control. <br /> 1. We will continue to stabilize the stream bed and banks of the <br /> channelized portions of Phil's Creek and the areas along the outer banks <br /> of the settling ponds. <br /> 2. We will close the temporary road, now being used, connecting <br /> to SR 1104. We will at the same time construct a new road, to be used <br /> for hauling away overburden, which will be paved if it is to be termed <br /> permanent as described in the ordinance. <br /> 3. We will not use our right-of-way easement to 1103 so long as <br /> we are operating a quarry at this site. <br /> 4. Water wagons or other acceptable dust inhibitors will be used <br /> when needed is the yard areas and on temporary roads to keep dust leaving <br /> the site to a minimum. <br /> 5. All future stockpiles and overburden piles will be located at <br /> least 200 feet from stream., on the site . <br /> .. _ ,mss-ar--r.•,--.ntr�--^. mss. - ..v--ti "'3-x--„°”'--+ c <br /> . <br />
