Please find the enclosed process water discharge permit No COG-500000. <br />Note the description and treatment corresponds with the situation at the site. <br />The operating pump has a design rate of 3000 gpm and is regulated by a <br />ground water level detection sensor. The pump only operates when the <br />ground water level rises above the sensor. Please revise the permit to include <br />temporary utilization of ground water reduction techniques due to proximity <br />to the Arkansas River and floodwaters. The commodity will be wet mined. <br />2. We have placed overburden material in an area in the southwest corner of <br />Phase 1 in order to further compact and stabilize the ground. This location is <br />in close proximity to the mining area. Please revise the permit to establish <br />the southwest staging area as the new process area rather than the initial <br />location in the northeast corner of the permitted area. Please refer to the <br />map accompanying the June z6`", 2000 annual report for specific dimensions <br />and location. <br />/:~ . ~, <br />Respectfully submitted, <br />~~ 6~' <br />Angela Bellantoni <br />
