Mr. Dustin Czapla 15 <br /> CDRMS <br /> September 24, 2021 <br /> (i)soil pH,texture, electrical conductivity,sodium adsorption ratio and any other <br /> parameters that the Operator/Applicant or Office deems necessary for proper <br /> soils characterization; <br /> (ii) indicate on a map, or in the soils narrative the location of each soil unit on <br /> the affected area where the above soil characteristics may be problematic as to <br /> suitability for a plant growth medium; and <br /> (iii) type, form and amounts of any soil amendments that may be necessary or <br /> recommended by the local Soil Conservation Service, Conservation District, or <br /> other qualified special district, and standard soil laboratory analyses and <br /> fertilizer recommendations (if available)for the types of plant species proposed <br /> to be established; or <br /> (iv) provide, as an alternative to Rule 6.4.21(17)(c), a plan of experiments to <br /> determine the type, form and amount of any soil amendments that may be <br /> necessary to fulfill the requirements of the Reclamation Plan. <br /> Response <br /> Prior to utilizing stockpiled topsoil or suitable alternative material, CJK will obtain representative <br /> soil samples and determine the following soil chemical characteristics: pH, electrical conductivity <br /> (EC), phosphorus (P), organic content (OC), cation exchange capacity (CEC) and particle size. <br /> Utilizing the laboratory data, CJK will decide if soil amendments are required to support the post <br /> mine reclamation effort. See Section 5.0 Rule 6.4.5: Reclamation Plan, Section 9.0 Rule 6.49 <br /> Exhibit I-Soils Information for details. If necessary, vegetative test plots will be established in <br /> accordance with an approved CDRMS technical revision. <br /> 24. Domestic water wells, Derrick Wood permit # 83329 (Constructed 8/8/1976) and <br /> Harry Hodson permit # 6616 (Constructed 8/15/1960), exist approximately 500 <br /> feet west and hydrologically down-gradient from the TSF and mill facility. Any <br /> failure of the TSF or mill containments pose serious risk to the wells and human <br /> health and safety. Please describe how the proposed operation can operate in a <br /> manner that will be protective of water quality and human health and safety. <br /> Response <br /> Mill processed ore will be disposed of in a multi-lined tailings disposal structure with leak <br /> detection. Leak detection is to confirm the structure is functioning as designed. In addition, <br /> surface and groundwater monitoring will provide analytical data to determine if the facility is <br /> functioning as designed. If design components fail, approved CDRMS corrective procedures <br /> and protocols will be implemented. <br /> See attached Appendix 7-1 Adjacent Landowners DWR permitted wells and their associated <br /> lithologic well. From a geologic perspective the wells downgradient of the mill are completed in <br /> glacial heterogenous till, sands, and gravels, may be as deep as 150 feet. <br /> CKL implemented operating and monitoring plan is designed to mitigate adverse environment <br /> and human health risks. <br /> Derrick Wood Permit#83320 (See attached Appendix 7-1)was approved by CDWR's, however, <br /> well completion records have not been filed or DWR has not posted Wood's well log data <br /> Harry Hodson well (permit#6616) (See attached Appendix 7-1) has not been located, and if the <br /> well exists, the well is not being used. Hodson's well is located on property currently owned by <br /> Phillips. The well log suggests the well completed in alluvial materials appears to be is <br />
