3.2.2 Monitoring Frequency <br /> The Plan has two phases: Baseline and Operational. Baseline Phase consists of sample <br /> collection that has already occurred prior to,or will occur subsequent to and in conjunction <br /> with, mining activity on the site; that is, after consultation with and approval by DRMS, the <br /> Operator will continue to develop its baseline dataset at the same time it commences <br /> mining operations. Operational Phase will occur on an ongoing basis once the baseline <br /> data is acquired;and will continue until mining ceases. <br /> 3.2.2.1 Baseline Phase (Prior to Mining Activity) <br /> RMCC has initiated its pre-operational water quality sampling program. Groundwater <br /> levels have been measured monthly since August of 2019 or before. Initial baseline water <br /> quality samples were collected in June 2021 at the following locations: Nix-Owens-Mon <br /> 4A, Nix-Owens-Mon 5A, Nix-RMCC-Mon 6, Nix-RMCC-Mon 7, and Nix-RMCC-Mon 8. <br /> RMCC Environmental Manager Scott Legg has discussed the 2021 results with DRMS <br /> Environmental Protection Specialist Eric Scott. RMCC sampled four wells again in April <br /> 2023. Though results are pending, the testing will confirm any exceedances and will <br /> provide results for analytes missed in 2021. Further, RMCC will continue monitoring for <br /> quality until it has five quarters worth of data,then proceed in the future with annual testing <br /> every June. <br /> The first round of subsequent samples was collected on April 17, 2023. Sample <br /> collections were attempted at the following dry wells: Nix-Owens-Mon 1, Nix-Owens-Mon <br /> 2, and Nix-Owens Mon 4. Nix-Varra-Mon 3 is a 1" well and is deemed not suitable for <br /> water quality sampling. Nix-RMCC-Mon 9, was installed on April 12, 2023, and will be <br /> included in future sampling events. Additional subsequent sampling events at all seven <br /> water quality locations will be conducted in June 2023, August 2023, and October 2023. <br /> Two additional sampling events at Nix-RMCC-Mon 9 will be conducted if deemed <br /> necessary by DRMS to collect up to five baseline samples at each well. At the end of the <br /> baseline phase, RMCC will submit a Baseline Data Summary report as a Technical <br /> Revision. <br /> 3.2.2.2 Operational Phase (Long-Term Operation) <br /> Water quality samples will be taken annually in June at each of the seven water quality <br /> wells for the duration of mining operations. The frequency of sampling for long-term <br /> monitoring can be modified in the future if water quality impacts are detected. Monthly <br /> water levels will continue to be collected at each monitoring well, however the Piezo wells <br /> may be removed after leak testing occurs. <br /> 3.2.3 Monitoring Parameters <br /> The Operator will conduct field and laboratory analysis on 37 different water quality <br /> parameters at each site, based on CDPHE Regulation 41, Tables 1-4.
