~~ <br />David Berry <br />March 1, 1990 <br />Page 2 <br /> <br />MLRD COMMENT: <br />S rp ings <br />1. Flow and field parameters were not recorded for Spring A2 during <br />April. Although it is appreciated that two measurements were made each <br />month, during March and May, the intent of the monitoring plan is to <br />quantify the approximate peak flow period. This often occurs in <br />April. Please explain the reason for missing the April measurement, <br />and please verify that monthly sampling will occur during future runoff <br />periods. <br />As discussed for Spring A2 above, the Spring C-1 was not sampled during <br />April, 1988: We acknowledge that additional samples were taken at <br />other times; however, the April measurement is considered to be very <br />important. Please explain the omission. <br />3. The comments at number 3 above also apply to Spring D. <br />RESPONSE: <br />JThe spoil springs were monitored as per the plan except for the April <br />reading. Depending on snow melt peak flows from the springs can occur <br />during April or May. It is CYCC's intent to follow the approved program and <br />all attempts will be made to obtain spoil spring flows during April. The <br />person responsible for obtaining the spring measurements is no longer <br />employed by CYVCC, therefore, it is not possible' to determine the exact <br />reason for not obtaining a flow measurement during April. <br />MLRD COMMENT: <br />4. Were Springs B-3, F, H, I, 0, EP-87-1, EP-87-2 and M2-87-1 dry during <br />May, 1988? If not, why were they not sampled? <br />RESPONSE: <br />Spring B-3 was flowing during the monitoring period, however a sample was <br />not obtained for full suite analysis. Spring C-1 was used as the sampling <br />point for full suite analysis for this portion of the mine. Springs A, B, <br />and C are all in the same immediate area, and it was decided to use Spring <br />C-1 as the sampling point. The field parameters for Spring B-3 are as <br />follows: Flow - 24 gpm, pH - 7.01, EC - 3530, temp. - 11oC. Springs F, H, <br />I and 0 was not discharging during the monitoring episode. Springs EP-87-1 <br />and EP-87-2 had insignificant distharge and were not sampled. Springs R, <br />and M2-81-1 were not discharging during the sampling episode. <br />MLRD COMMENT: <br />5. Please locate Spring 1861100 on the spoil spring map, and add it to <br />Table 1 of the Annual Hydrology Report. <br />
