However, this is often also very <br /> expensive and may not provide a permanent <br /> solution, depending on the configuration of <br /> the valley and the stream dynamics. <br /> The other alternative in the case of waste rock <br /> or tailings located in a pond is to drain the <br /> pond, thus drying up the area. <br /> Initial costs <br /> Cost of this BMP will vary greatly depending <br /> on the volume of material to be moved and the <br /> CONSOLIDATED WASTE ROCK SITE AFTER <br /> CAPPING AND REVEGETATION <br /> 17 <br />
