When the sprinklers are not in service, water trucks will be used to <br />water the active disposal area at least every 3 hours during the day, <br />and as needed at night to minimize fugitive emissions. <br />iv. Water truck operation as previously described will occur except in <br />the <br />following circumstances: freezing conditions, rain, or snow. As used <br />here, the term "freezing conditions" means weather conditions severe <br />enough to clog the water truck due to freezing. Cemex shall take <br />reasonable precautions, including but not limited to storing the water <br />truck in a heated garage at night, to prevent such freezing conditions. <br />c. Cemex agrees to limit the active disposal or working area of the CKD storage pit to 3 <br />acres at any time. <br />Inactive or unused portions of the pit shall be covered with rock or <br />treated with hydroscopic materials to minimize fugitive emissions. <br />ii. Signage or berms should be used to delineate the 3 acre active <br />disposal area. <br />d. Cemex shall compact and stabilize the CKD disposal pit as required by 950PB0082, <br />section II, condition 13.5.4. <br />43. Cemex shall treat haul roads with a magnesium chloride or calcium chloride <br />solution as often as necessary to maintain a surface crust, as required by permit condition 13.5.3. <br />Such solution shall be applied to the haul road to the CKD disposal pit at least every six months. <br />The solution shall have a concentration of at least 32 percent magnesium chloride or calcium <br />chloride by weight. As an alternative, Cemex may substitute another hydropscopic material, so <br />long as such treatment is at least as effective as the solution described in this paragraph in <br />controlling fugitive emissions. <br />44. Cemex shall document all reported observations or complaints from citizens, <br />inspectors, contractors, or employees of fugitive or excess emissions. Cemex will investigate <br />each occurrence and will document its findings and any corrective action taken or implemented. <br />45. Cemex shall install and begin continuous operation of dust control equipment <br />within the A-Frame, but in no case shall Cemex install such equipment prior to Division <br />approval of the requisite revision to the construction permit. Cemex shall submit a complete <br />application, as defined in Regulation No. 3, to amend its permit to require such dust control <br />equipment within 30 days of the effective date of this order. Cemex shall construct such dust <br />10 <br />
