Based on what is <br /> currently known,the primary target screen interval would include the Codell,but extending up <br /> approximately 5 feet above the Fort Hayes/Codell contact(assuming no saturation is observed in the Fort <br /> Hayes). If the Fort Hayes is found to be saturated during drilling, it is recommended that nested wells be <br /> installed to monitor both intervals separately. <br /> This analysis and associated opinions are based on site records provided by GCC,review of DRMS files,and <br /> search of readily available reports and published literature. This analysis does not address and did not <br /> include a thorough review of environmental risks not associated with quarry extraction and reclamation. <br /> Proper containment and control of hydrocarbons appeared to be in place based on a brief site tour,but formal <br /> assessment of controls for hydrocarbons or other chemicals managed at the facilities was not within the <br /> scope of this study. References specifically cited in this report are provided in Attachment B. As mining <br /> approaches or progresses into the third mine panel(Years 16-25)additional field studies may be needed to <br /> confirm that conditions described herein persists to the east. <br /> We appreciate the opportunity to work with you on this project. I look forward to meeting to discuss any <br /> questions about this report. <br /> Sincerely, <br /> r } <br /> Bence V.
