Mr. Boulay <br />1993/94 AHR Responses <br />Page 5 <br />8. •A turbidity measurement for G-la was inadvertently missed. <br />.Laboratory pH, Specific Conductance and TSS were missed by the laboratory during June <br />and September. Attached aze laboratory analysis sheets which Gsts all the other parameters <br />analyzed. <br />.Flows on 4/18/94 and 5/17/94 were too low to obtain a sample. The 5/17/94 visit has been <br />added to Table F-1. Please find a revised page (7 of 8) enclosed. <br />9. Please find a revised page 7 enclosed that annotates SOM-127-H and JMB-12. <br />10. Please find a revised Table of Contents page enclosed. <br />11. .There was no water in SG-1 during WY 1994, therefore, no field parameters. Lab data from <br />another resource was provided in ertor. Please find a revised Table H-1 (page 1) enclosed. <br />•A manganese measurement of 0.21 mg/I has been added to the revised Table H-1 enclosed. <br />Errors have been corrected and TSS added. <br />.There was insufficient depths of water in GP-3 and GP-4 to obtain samples throughout WY <br />1994. Please find a revised Page 1 of 6 of Table H-1 annotated with this condition. <br />•Fe and Mn analyses were missed by the laboratory. <br />.Laboratory measurements of pH, Specific Conductance, and TSS were not routinely <br />completed by the laboratory for the reasons described previously. Please find a data sheet for <br />other parameters attached. <br />.Laboratory pH, Specific Conductance, and TSS were not routinely completed by the <br />laboratory for the reasons described previously.

Please find revised pages 1 and 6 of 6 of Table H-1 that cortects the duplicate footnote (an <br />asterisk replaces the first footnote number ]). <br />13. Mme seepage inflows were very low in WY 1994. The total inflow is estimated by adding up <br />all of the imported volumes and loss estimates and deducting this from the total water <br />discharges (exported) from the mine, resulting in an amount that is assumed to have been <br />contributed from the mine (natural inflow). h` inflows up to 50 gallons per minute (gpm) are <br />encountered, they are typically of short duration (less than two weeks and sometimes only <br />
