EEXHIBIT - S <br />Structures within 200 feet <br />As shown in Exhibits C and D, there is an 8 inch, high pressure, liquid petroleum pipeline <br />that runs north south through the permit area owned by the Kaneb pipeline company. As <br />requested by the pipeline owner, Coulson will mine no closer than 50' from the pipeline <br />and maintain a 3H:1 V mine wall slope in the azea adjacent to the pipeline. Prior to <br />excavation, the pipeline and 50 ft setback will be located and staked out. <br />Hillsborough Ditch <br />The Hillsborough Ditch occurs at a distance greater than 200 ft from the permit area to <br />the south. Due to potential hydrologic effects to the ditch, a plan to monitor and replace <br />water flow in the ditch is as follows; <br />Monitor baseline flows <br />Baseline or pre-mining ditch flows will be determined by taking flow measurements, and <br />surveying in cross sectional azeas at two locations shown in Figure 1 (approximately <br />1000 R upstream and 1000 ft downstream of the proposed permit azea). Flow <br />measurements will betaken during times of average ditch flow to be determined by <br />communication with the ditch rider, Dave Graves. Flows will be calculated and ditch loss <br />to the ground will be calculated from the field data. <br />Monitor flows during mining <br />Flow measurements will be taken at the same locations and using the same methods as <br />described above. Measurements will betaken daily until the pit dewatering operation has <br />reached steady state (pumped down) performed weekly thereafter. Ditch loss during <br />mine de-watering will be calculated and water will be returned to the ditch in the amount <br />calculated to be in excess of baseline ditch loss. A flow meter will be installed on one of <br />the dewatering pumps to measure replacement flows if it is determined replacement is <br />needed. <br />
