The well monitoring program was further modified through the submittal of a new plan incorporated into Kaiser Steel Corporation's Hydrologic Monitoring Report for 1987, received by the Division on April 1, 1988. This new plan was approved on May 25, 1988 as Technical Revision No. 8. That monitoring plan was described in Kaiser's 1987 Hydrologic Report. Wells monitored for water levels in 1987 and 1988 included 2L, 2W, 14R, 15L, 15C, 15T, 19A and 21A. In 1988, wells 2L and 19A were also monitored for the water quality parameters listed in the 1987 report. Stipulation No. 20 which was included in Technical Revision No. 8 also requires that water quality data be collected for Well 15T and requires that water quality data be gathered on a biannual basis. On April 5, 1989 the Division received Technical Revision No. 10. This revision suspends hydrologic monitoring at the site. Therefore, Stipulation 20 is no longer necessary. The requirements of Stipulation No. 4 have been met. The required monitoring showed no impacts on the groundwater due to the test pit mining. With no further disturbance planned at this site and with only reclamation allowed in the near future, no additional groundwater monitoring is necessary. Therefore Stipulation No. 4 is being removed from the Findings Document. 2. Stipulation No. 5 requires an augmentation plan for use of water from an industrial well. The plan was submitted as required. However, the well permit may have expired. The permit renewal allows only reclamation. Unless a revised mine plan is submitted and the bond increased, no mining will occur. Therefore there will be no future need for this well. This stipulation can be removed from the Findings Document. The remainder of this section remains as presented in the 1983 Findings Document. The Division finds there is sufficient information within the permit and renewal applications to find this section in compliance. VII. Probable Hydrologic Consequences of Mininq and Cumulative Hvdrologic The discussion in the 1983 Findings documents any potential hydrologic impacts of the mining activity. The current test pit, excavated under the Dry Mine Plan, does not intersect the groundwater table, and there are no significant surface water drainages which intercept this pit. Groundwater The 1983 Findings anticipated very little impact of the mining activity on the local groundwater system if the Dry Mine Plan were followed. Following issuance of the permit, the only activity to take place on the property, i.e. excavation of the test pit, was conducted according to this plan. Subsequent groundwater monitoring in the pit area has shown no adverse impacts on either the quality or quantity of ground water in that area. Infilling of the pit, proposed as part of the renewal of the permit allowing only reclamation, should eliminate any potential for future impacts. -8-
