Groundwater & Surface -Water Monitoring Response Plan <br />Oil Shale RD &D Project <br />American Shale Oil, LLC <br />The objective of the surface -water and groundwater monitoring program at the American Shale <br />Oil, LLC (AMSO) oil shale research, development, and demonstration (RD &D) project is to <br />ensure timely recognition of any impacts to water resources that have the potential to be related to <br />site operations during and after pilot retort testing. Potential impacts will be identified by <br />comparing monitoring results to the monitoring data and trends reported for the Baseline <br />Monitoring Program. The baseline program was conducted to establish baseline surface -water <br />conditions in Black Sulphur Creek downstream of the site and baseline groundwater conditions <br />within the B- Groove, L3, and upper Wasatch Formation hydrostratigraphic units at the site. In <br />accordance with DRMS and BLM requirements, the program included monitoring water levels in <br />on -site wells, monitoring flow rates in Black Sulphur Creek, and collecting surface -water samples <br />from Black Sulphur Creek and groundwater samples from monitoring wells MWP1 -L3, MWP2 - <br />BG, MWP2 -L3, MWP2 -WS, and HB -L3 during five quarterly monitoring events conducted <br />between June 2009 and September 2010. Water -level monitoring has continued since completion <br />of the baseline characterization, with the data providing a continuous record of baseline (pre -pilot <br />testing) measurements. Groundwater monitoring wells and the Black Sulphur Creek sampling site <br />are located as shown in Figures 1 and 2, respectively. <br />1.0 Active On - Site Monitoring & Response during Pilot Retort Operations <br />During operations, water levels and water chemistry will be closely monitored to ensure <br />confinement of the pilot retort interval and early recognition of any potential threats or impacts to <br />water resources. Water level monitoring will be accomplished by using in situ pressure <br />transducers and data loggers that will continuously record pressure -head readings in the L -3 <br />hydrostratigraphic unit at wells MWP1 -L3, MWP2 -L3, and HB -L3 and in the B- Groove <br />hydrostratigraphic unit at well MWP2 -BG. Water level monitoring data will be accessed via a <br />direct read cable that connects the pressure transducer to a laptop computer at the wellhead. When <br />connected to the instrument, pressure -head readings will be viewed in real time directly from the <br />data logger, and downloaded to a laptop computer to store and view the continuous record over <br />time. During the data reduction process, pressure -head readings will be reduced to water level <br />elevations, corrected to remove barometric pressure influences, and exported to MS Excel for <br />compilation and graphical display. <br />1 <br />
