Box 1470 Rifle, CO 81650 Dear Mr. Saubestre JUL 13 2016 GRAND jutquiuti iE u OFFICE DIVISRECLAMATION MINING & SAFETY Our staff has reviewed American Shale Oil, LLC's (AMSO) Julyl0, 2016 request to amend the approved Plan of Development (POD) by eliminating the requirement of three years of post - operational water monitoring. AMSO made three attempts during 2012 (4 days) and 2013 (15 days) with electric heaters to start the pilot experiment and operate as per their approved POD. All of the heaters failed during start-up and prior to retorting and pyrolyzing the targeted oil shale. No further attempts were conducted In April 2016, AMSO made the decision to cease firture project operations, and to commence immediate site decommissioning and surface reclamation. Temperatures around the production wells never reached temperatures that might have any adverse impact on the underground sources of drinking water (USDWs). In addition, the historical water data analysis submitted indicates that there is no evidence that the identified USDWs in the UIC Permit Statement of Basis were impacted by these startup attempts. Since AMSO heating attempts never reached the operational status of the POD, no pyrolyzation occurred, and there is no evidence of water quality impacts, the requested amendment to the POD is approved. Authorization from Colorado Division of Reclamation Mining and Safety and the EPA may also be required. If you have any questions, please call Paul Daggett, our Mining Engineer, at 970-878-3819. Sincerely, OLauren Brown Assistant Field Manager
