„i <br />Page 4, Item B.6.: <br />Snowmass will provide a preliminary spring survey now and will commit to a <br />more complete study when weather allows. It is understood that a commitment to <br />a complete spring survey will be a condition of an approved Permit but will not <br />cause a delay in the granting of such a Permit. <br />Page 4, Item B.7&8.: <br />Snowmass will submit mine inflow maps on updated mine workings maps of the <br />No. 1 and No. 3 mines. The maps used will be similar to maps A and B of the sub- <br />sidence section and will depict surface streams and topography. All individually <br />significant inflows within accessible areas and discharge points from mined out <br />areas will be plotted on these maps. Flow measurements will be taken where pos- <br />sible or otherwise will becstimated and pH, conductivity, and temperature measure- <br />ments will be provided for each plotted inflow. Inflows which are immeasurably <br />small or are judged as not contributing a large percentage of the total daily <br />water production will not be plotted or tested. However, in areas where a high <br />concentration of small inflows occur, an effort will be made to plot and describe <br />the area as a whole. <br />A water study as outlined on Page 1, Item III.A. of the Permit Application <br />Review Comments letter dated January 6, 1982 will be provided. <br />Snowmass will commit to a annual submittal of updated inflow maps to the <br />Division. The maps will be similar to those previously described. A description <br />of new, significant, inflow sources will be included along with an updated de- <br />scription of all active, previously identified sources. <br />Page 5, Item B.10.: <br />The collection of baseline water quality data for Middle Thompson Creek is <br />currently in progress. Existing surface water sampling stations located on Middle <br />Thompson Creek, up and down stream from areas to be affected by mining, will be <br />plotted on a suitable map. The map and all accumulated data not previously sub- <br />mitted will be provided to the Division, Additional monitoring wells in the <br />Middle Thompson Creek area will not be required. <br />Page 5, Item B.11.: <br />Snowmass will continue to collect data on water levels and water quality <br />from existing bedrock monitoring wells in the mine area. All collected data <br />will be submitted to the Division. <br />The existing piezometer bore holes in Mine No. 3, mentioned in the ground- <br />water hydrology section of the application, will be preserved for possible use <br />in the future. <br />Page 6, Item B.12.: <br />Water held in the conveyor washdown ponds will be analyzed for all required <br />baseline water quality monitoring parameters. Information on the physical and <br />chemical properties of any surfactant or antifreeze agents used at the to ad out <br />will be sought from the manufacturers and provided to the Division. <br />
