damage would not result from this activity. On July 21, 1992, the Division approved relocation of a portion of the Amoco oil pipeline in order to remove it from areas to be undermined. Section VII - Hvdrolooic Monitorino Ground Water Monitoring: Cyprus Empire is monitoring eleven bedrock wells and three alluvial wells Par water quallty; with one well (BF-5) to be constructed after the No. 9 Refuse Disposal Area has been reclaimed. Cyprus Empire has been meeting or exceeding the level of monitoring of these wells as described with one exception. Tables 1 and 8 of Exhibit 29 of the permit application (Water Quality Monitoring Manual) states that Hydroxide will be monitored annually for seven of the eleven bedrock wells. In reviewing the 1991 Annual Hydrology report, it was noted that this does not appear to be occurring. Surface Water Monitoring: The Williams Fork River is monitored upstream and downstream of the mine. Discharges from two mine dewatering wells, a prelaw spoils spring and two sewage treatment ponds are also monitored on a regular basis. In addition, discharges from sediment ponds are monitored using NPDES requirements if and when they discharge. Again, Cyprus Empire has been meeting the monitoring requirements of its permit, as stated in Exhibit 29 of the permit application, with a single exception. Table 4 of Exhibit 29 of Cyprus Empire's permit commits the company to monitoring zinc only on a monthly basis although the mine's NPDES permit requires that Cyprus monitor zinc from its two mine discharge wells and the No. 1 spoils spring on a bimonthly basis Discharge monitoring reports received from Cyprus, however, indicate that the mine has been monitoring zinc twice a month. Section VIII - Mine Ownership and Control Minor Revision MR-23 updated mine ownership and control information for Cyprus Empire on 7-27-92. Section IX - Decision to Recuire Revision The following items pertain to various portions of Cyprus Empire's permit which will need to be revised. 1. Heqin sampling all wells for hydroxide as described in the permit ar seek to revise the permit to reflect current sampling procedures. 2. Revise Table 4 of Exhibit 29 to reflect both NPDES requirements for zinc monitoring and actual sampling frequency. 3. Revise Section 4.05.18 to designate areas of the mine as stream buffer zones. Revise Section 4.05.2 to describe the location of stream buffer zone markers. 9
