holes will be fitted with these devices. The thermocouple wire will be cut to <br />lengths specified by Project Manager, fitted with a small down -hole weight and a <br />male connector, and then suspended in the drill holes specified by the DRMS <br />project manager. DRMS will install the thermocouple devices. <br />1.5 GPS Location of Boreholes <br />All borehole locations will be logged using a handheld GPS unit. Coordinates <br />must be logged and reported to the DRMS Project Manager in NAD83, UTM <br />coordinates. <br />1.6 Borehole Abandonment <br />The boreholes that are not cased and equipped with a thermocouple will be <br />abandoned upon completion of stratigraphy logging. Abandonment shall consist <br />of backfilling the boring with cuttings to within 8 feet (8')of the surface. <br />Hydrated bentonite chips shall be placed between 8 feet (8') and 3 feet (3') of the <br />surface. Earthen materials will be used to fill the remaining three feet (3') of the <br />borehole. <br />Task 3- Surface Fire Prevention <br />Due to the current drought conditions, and the likelihood of the drilling encountering <br />burning coal, surface fire prevention measures must be implemented during drilling <br />activities. Surface fire prevention will include creating a 15'x15' drill pad at any drill <br />location that is surrounded by vegetation. The pads will be used to contain hot cuttings, <br />and must be cleared of vegetation. A 500 gallon water trick must be on -site during <br />drilling activities. <br />Project Deliverables <br />Shannon & Wilson's drilling subcontractor will provide the well casing for the 10 cased <br />boreholes, and a drill log with GPS coordinates for each borehole. Core will be logged, <br />boxed, and delivered to the DRMS project manager <br />Schedule <br />The initial site mobilization is scheduled for October 29, 2012. Drilling activities will <br />begin on October 30, 2012. Drilling will occur in 10 -day shifts with four -day breaks. <br />Tentatively, drilling will occur on the following schedule (as necessary until site work is <br />completed): <br />First 4,l6hilization: Monday, October 29 through Wednesday, November 7, 2012. <br />First Break: Thursday, November 8 through Sunday, November 11. <br />Second Mobilization: Monday, November 12 through Wednesday, November 21, 2012. <br />Second Break: Thursday, November 22 (Thanksgiving) through Sunday, November 25. <br />Third Mobilization: Monday, November 26 through Wednesday, December 5, 2012. <br />3 <br />
