Long <br />Di~isiun Durclor <br />The Division of Minerals and Geology has completed review of the 1999 Annual Hydrology Report for <br />the Lorencito Canyon mine. Due to the continued delay in start-up of mining operations at the site, the <br />data recorded continues to reflect baseline hydrologic conditions. The Division approved a reduction in <br />the frequency of sampling in early 1999. <br />Water level and quality remains basically unchanged and parameters continue to reflect baseline <br />conditions. <br />Two minor errors were noted as a result of data review. For bedrock wells, the data sheet should reflect <br />units of measurement as feet rather than cfs. Also, for well M W-31, the data entry of 381.70 feet should <br />likely be 281.70 feet, given the total depth of the well. Please correct this information in future reports. <br />The Division has no further questions at this time. Thank you for conducting monitoring in accordance <br />with your approved plan. <br />Sincere ~~ '' <br />ti'~~~~ <br />Ken[ Gorham <br />Environmental Protection Specialist <br />STATE OF COLORADO <br />cc: Dan Hernandez, DMG <br />
