standards in place that could lead to revocation of the Land Use Change Permit if continued <br />violations of the permit occur over a period of time. <br />15. Potable Water and Sanitary Facilities <br />Similar to other gravel pits in the area, portable toilets will be provided by a local service provider <br />at the main facilities area where the plants are located. Due to the reduced life span of the <br />operation, only porto-potties will be used on site for sanitation. Potable water will be provided <br />through a bottled water supplier like Deep Rock. The estimated amount of potable water to be <br />delivered to the site is 100 gallons per month. The potable water will be stored and dispensed in <br />the office trailer which will be located in the facilities area. <br />16. Water Quality Concerns <br />Since the gravel to be mined is below the water table, a pit pump must be used to dewater the pit <br />prior to mining. As shown in Exhibit G - Water Information, the pump will only pump clean <br />groundwater to discharge into the River. The approved NPDES permit for the site allows for <br />sediment levels between 35 and 70 milligrams per liter total suspended solids. This level is far <br />lower than the average sediment load of the River itself. USGS gage water quality data show that <br />the River runs an average flow that is much higher, with flows during runoff events and spring <br />thaw reaching 1500 to 2000 milligrams per liter or more. The discharge from this operation will be <br />better in quality than the River itself. <br />The portable plants and associated fuel tanks may be located in the pit bottom as shown on Map C- <br />2, but will be removed if there is any chance of flooding the pit from the river. The staff gauge <br />plan discussed in subsection 7.0 of Exhibit D. <br />17. Dust and Smoke Control <br />Dust and smoke is regulated through the State Air Permit. This pit will produce minimal fugitive <br />dust due to the fact that is a wet pit. The material that is mined will have high moisture content and <br />will naturally suppress dust. Also, this gravel has a low fines content; for this reason, it's <br />processing results in very little fine waste. The portable crushing and screen plant will move with <br />Scott Pit March 10 D-14
