The NS 2014 Mine Plan Modification is currently under an <br />environmental assessment and review by the BLM. <br />To reach this new production goal NS will build an additional facility that will expand <br />the current mine plant footprint by approximately 90,000 square feet. This new <br />facility will include a new process building (approximately 150 x 115 feet), a new <br />packaging and warehouse building (approximately 265 x 225 feet), and a new dry <br />handling, screening and storage building (approximately 190 x 80 feet). The height <br />of the new facility is expected to average 50 feet. The warehouse facility will have a <br />load -out arm with paved truck access. A paved parking lot (approximately 133 x 182 <br />feet) will also be built to the south of the existing plant. New cooling towers and <br />boilers will be installed adjacent to the existing plant on existing disturbance. Plant <br />expansion will increase the current disturbance associated with existing <br />manufacturing facilities by approximately 8 acres. Also, a new treatment pond <br />totaling approximately 7 acres will be built. Access roads (15 feet wide) and top soil <br />piles may add an additional disturbance of approximately 4 acres. The attached <br />figure shows the conceptualized processing plant expansion areas. <br />On October 1, 2014, Sodium Lease C00011998601 was modified by the BLM to <br />include additional land: Sec. 35, Lots 1-4, inclusive, T.1S., R.98W., 6th Principle <br />Meridian, Colorado containing 156.340 acres (more or less). Please note that the <br />2014 MPM was submitted before the lease modification and does not reflect this <br />new addition, but will soon be updated. <br />SPECIALIZING IN PROFESSIONAL GEOLOGICAL, ENVIRONMENTAL, HYDROLOGICAL, GEOTECHNICAL AND PERMITTING SERVICES <br />
