Weber St. Third Floor <br /> Stockton, CA 9W02 <br /> Subject: J.H. Simpson Co. <br /> 4025 Coronado Ave. <br /> Stockton, California <br /> Dear Mr.Wong: <br /> This letter confirms our scheduled drilling date of October 30, 1998, at the above <br /> referenced site. <br /> As you requested, we will be prepared to develop the monitoring well the same day. As <br /> we discussed on the telephone, the California Well Standards (Bulletin 74-90), produced <br /> by the California Department of Water Resources requires a minimum of 24 hours for <br /> the grout to "set and begin curing before construction operations on a well can be <br /> resumed". As such, we recommend that the developing and sampling be postponed <br /> until at least the following day. We will however develop the well the same day if so <br /> directed by your office. Please call if you have any questions or need additional <br /> information. <br /> Respectfully, <br /> JJW GEOSCIENCES Inc. <br /> F. William Welter <br /> Project Manager <br /> Rancho Cordova South Lake Tahoe Atascadero <br /> 11350 Monier Park Place, Rancho Cordova, CA 95742 Tel: 916.853.8025 Fax: 916.853.8029 <br />
