placement of an aerator in the western cell. This aerator may be turned off after the one in the eastern cell is turned <br />on. <br />Due to the fact that the pH is being elevated, it was decided to have sulfuric acid available in the event a pH <br />adjustment was needed prior to the effluent discharging from the system. The chemical and equipment for this <br />procedure is housed in the chemical storage building located on the west side of the west cell as shown on Map 32. <br />This system will be used only if the effluent approaches the pHdischarge limitation of 9.0. <br />In 2006, the sodium hydroxide system was replaced with an electro-coagulation system which achieves the same <br />result through ionization and agglomeration of particulate iron. The treatment ponds and associated surface <br />facilities and systems will be removed and disturbed areas reclaimed when no longer needed for treatment of mine- <br />water discharge. Reclamation plans for this facility are summarized on page 2.05-105.1. <br />lORT Dewatering Wells (Eastern Mining District) <br />(Note: Text for lORT Dewatering Wells moved to pages 2.05-50 through 50.6) <br /> <br />MR08-230 2.05-77.1 11/20/08 <br />
