Access roads that are currently existing will be utilized during the operations <br />at this site. The approximate dimensioa~s of these roadvsys are 2,000 feet by <br />25 feet. (1.15 acres). <br />The eventual area to be affected by gravel extraction ie 555 feet by 650 feet <br />(8.25 acres). Included in this 8.25 acres are areas listed belay. <br />1. A portion of the exietir~g lake. <br />2. The area northeast of the existing lake that is currently unmined, except <br />that the topsoil has been removed. <br />3. The asphalt plant site and gravel stockpile area. <br />The only L~rovemente necessary for the existing roads will be the application <br />of a dust suppressant to oorstrol fugitive dust. This agent will probably be <br />magnesium-chloride or a similar substance. <br />water will be nec.~essary to both the crusher plant and the asphalt plant for vas <br />as a wet suppressant to control fugitive duet during the operations of those <br />plants. Small quantities of water will be needed, however, ar~d will be available <br />from the existing lake. <br />As previously established, mining of sand aryl gravel will occur adjacent to an <br />existing laloe. it will then obviously be necessary to dewater this lake and <br />maintain a dewatered situation for the duration of the gravel processing <br />operation. Thies lake is filled by grau~d water. It is believed that the <br />dewatering of this site will not adversely affect either the quantity or quality <br />of any surface water systems. Additia~nally, due to the elevation of this site <br />in relation to the Colorado River and the proximity to the river, it is also <br />believed that ground water systems will not be affected. <br />Dewatering will be performed In a safe and responsible mariner in that discharc,7ea <br />t will rot be placed immediately into the Colorado River. Discharge will instead <br />be into a slough that ie southwest of the lake and then will ba conveyed to the <br />river. Discharges into the slau~i will be of high quality water. Raters that <br />' have been naturally clarified will be discharged and monitoring of these <br />discharges will be according to Colorado Department of Health Standards. A <br />NP'D~S Permit shall be obtained. <br />' It Se recognized that the State I~gineer has specific requirements concerning <br />the administration of water rights. ~lication-ehall_be_made_to_the_State. <br />Hrgineer for a Well Permit in order that water augmentation may be addressed. __ <br />' Activities at this site can be categorized into two operatiaos. <br />I -7 <br />
