2000 AHR Review <br />Data collected under the 2000 calendar year included all stations approved under the <br />original plan but on a reduced schedule. Also reported in the 2000 report were field <br />data and water quality data collected in March 2001. This data should be considered <br />the most representative of pre-mining conditions. Some increase in total dissolved <br />solids in Lorencito Canyon is noted and minor changes in alluvial water levels and <br />bedrock water levels are noted. <br />2001 AHR Review <br />The operator conducted sampling in March 2001 for surface and alluvial stations. Upon <br />commencement of mining activities in October, the operator began monitoring as <br />approved under PR-01 for surface mining in Jeff Canyon. Water quality is effectively <br />unchanged due to mining activities, likely due to the limited mining activities conducted <br />during the year. An increase in TDS of 10 mg/I in the Purgatoire River is between the <br />upstream and downstream stations, is noted, and likely due to higher total dissolved <br />solids in discharge from Lorencito Canyon. Due to drought conditions, no discharge <br />from mine sediment ponds occurred in 2001. <br />The Division has no further questions at this time. Thank you for conducting monitoring <br />in accordance with your approved plan. <br />Sincer ly, <br />1 <br />Ke t Gorham <br />Environmental Protection Specialist <br />cc: Dan Hernandez, DMG <br />
