Attachment A <br />3. Natural gas well drilling make-up water <br />These water management methods are not considered viable as they do not offer a more <br />cost-effective, environmentally sound alternative or may not be as reliable in treating the <br />retort water long term. In addition, these treatment methods would also require long-term <br />permit management and field maintenance. <br />6. Please submit specifications and costs for acquisition (lease or purchase), <br />installation, operation, and removal of a treatment facility for the retort water <br />discharge (including periodic sludge removal, or filter pack replacement and disposal). <br />The time frame for the water treatment bond to be required is the estimated S years it <br />will take to complete reclamation and revegetation of the Logan Wash site. The <br />Colorado Department ojPub[ic Health and Environment (CDPHE) has jurisdiction of <br />the quality of water that may be discharged from a treatment plant throughout the <br />period of the plant's operation. IfDRMS uses the bond to contract for water treatment <br />during t/:e estimated S year reclamation period, and if continuing treatment is <br />necessary to meet CDPHE requirements following reclamation, CDPHE has the <br />authority to order Occidental Oi[ Shale, Inc. and any other responsible parties that may <br />be identified to continue to meet t/rose requirements eit/:er t/:rough continued wafer <br />treatment or other suitable actions. <br />Response: <br />OOSI does not believe that the installation of a mechanized water treatment facility is a <br />cost effective solution for treating the small rate of discharge from the Logan Wash Mine. <br />Passive evaporation is clearly the most cost effective and environmentally sound solution <br />to treating the retort water dischazge. Furthermore, it would seem that the installation of <br />a water treatment plant on the mine site would require a technical revision to the permit <br />and that the disturbance associated with the plant's installation and power corridor would <br />require further bonding. Even if such a plant were constructed, the permit could not be <br />closed because the potential long-term treatment of retort water would still exist along <br />with unreclaimed lands. <br />OOSI reseazched the costs of a mechanized water treatment facility. These costs aze <br />outlined below. <br />10 <br />
