information garnered from the LDS (see Protocol _ below) to comply with Rule 8.0. including notification of the OMLR within 24 hours of CC&V having knowledge of such exceedences, a written discussion of precautions and corrective actions undertaken and planned submitted to the OMLR, with a timetable for implementation, and a written report satisfying Rule 8.2.3. Corrective actions will include a specific plan of corrective action to be timely implemented to control, reduce, or otherwise minimize movement of leach solution in harmful quantities moving outside the permit area. Though any such circumstance will necessitate case- specific measures, CC&V will address testing of areas through manipulation of leach solution application. [?At any time when redeployment of applied water has not mitigated the migration of leach fluid from the pad to the environment, CC&V will cease addition of additional water to the pad.?] d. The results of laboratory analyses for the listed parameters will be provided to the OMLR along with the sampling locations, date and time of sampling, type of analyses, and applicable laboratory sample number. TABLE 1 - 30-day Average Threshold Concentrations - Underdrain PARAMETER UNTIL DECEMBER 31, AFTER DECEMBER 31, CNW„p 1-0 mg/l 0.5 mg/I pH 9.0 s.u. 9.0 s.u. Leak Detection System (LDSI: If the CNw„o and pH in the LDS exceeds both of the values listed in the following Table 2 and the flow criterion is met, CC&V shall undertake the following steps: ~ H atut~ a. Notify the OMLR by telephone within wer-ktftg-daps of having knowledge of the combination of elevated water-quality parameters and sustained flow b. The frequency of monitoring shall be increased to~ samples per 7 days until one or more of the criterion concentrations listed in Table 2 are not exceeded or the flow criterion is not met or until it is shown to the satisfaction of the OMLR that the increased frequency is not required because pertinent information is not being generated. c. If both of these centrations listed in Table 2 are exceeded for more than days, or if the levels rise to <_mg/I CNWAp and _<9.5 s.u., and if the flow is consistent throughout the intervening period, CC&V will consider there to be a defect in the active Cresson Valley Leach Facility that allows CN-bearing solution from that facility to move into the surrounding environment and will combine this information with the information garnered from the Underdrain system (see Protocal _ above) to comply with Rule 8.0., including notification of the OMLR within 24 hours of CC&V having knowledge of exceedences, a discussion of 3
