(Chevron) has contracted WWC Engineering (WWC) to assist in attaining bond release for <br />the former Edna Mine, Permit Number C-80-001, located in Routt County, Colorado. The Edna Mine is in <br />permanent cessation, reclamation is nearly complete, and the site is approaching potential final bond release. <br />Prior to and during mining activities numerous monitoring wells were drilled within and extending outside of the <br />permit boundary. The monitoring wells are constructed of steel/PVC casing ranging in diameter from 1"-7" and <br />depth from tens to hundreds of feet. The construction of the monitoring wells was for observation not <br />production. The monitoring wells had numerous purposes including attaining water level and/or water quality <br />data. The referred monitoring wells have since been removed from the Edna Mine groundwater monitoring <br />program. The monitoring wells are located in T 4 & 5 N, R 85 & 86 W, Routt County, Colorado. <br />Seven (7) monitoring wells are to Transfer Ownership in accordance with state regulations under this cover; 05- <br />01-0007, GMC3, UNK3, Oka, OK2, GMC2 and 05-03-0005. The monitoring wells are not registered and <br />therefore, according to verbal communication with the Colorado Office of the State Engineer (CSEO), Forms <br />GWS-12 (Registration of Existing Well) and GWS-68 (Existing Well Information) were completed and mailed <br />08/26/08. This submittal is in response to a determination by CSEO dated 08/27/08 that Forms GWS-46 <br />(Monitoring/Observation Water Well Permit Application) and GWS-68 are more applicable to this scenario. The <br />appropriate Forms and Filing Fee (Attachment A) are enclosed under this cover. <br />Should the Colorado Office of the State Engineer have any comments or concerns regarding this submittal, please <br />contact me or Troy Summers at your convenience. <br />Sincerely, <br />Beth Heesen, P.G. <br />Project Manager <br />TNS <br />Enclosures <br />File: 99-144 <br />cc: Leach (Chevron), Musick (CDRMS), Weinman (Permit), Dick, Maplewood (Dulan), Hoeptner (Hayden), <br />Redd
