A cement plug was affixed above the plug in the open hole <br />and the site was graded into the contours of the area with the backhoe. The disturbance was <br />seeded and hand raked with a mixture of high plains fescue. All casing and reclamation debris was <br />removed from the sites and the holes were marked with a "t-bar" fence post. <br />The slurry mixture consisted of approximately 5.5 gallons of water to each sack of type II cement. <br />The pumping and mixing procedures were monitored by Pronghom Geologic Services personnel, <br />along with Kerr Coal personnel at each well site. <br />Volume was calculated for an open drill hole and not the volume of the well casing. In each case the <br />open hole diameter was estimated to be 3 inches greater than the inside diameter of the monitor well <br />casing. In each instance, the actual slurry fill exceeded the calculated volume of the open hole. <br />I hope this narrative answers some of your questions and concerns. Please do not hesitate to <br />contact us at the above numbers if I have left out any details. <br />Thank you, <br />Glenn E.
