2008- 023 Historical and baseline data on various groundwater characteristics, including wet season and dry season (minimum 1 year) monitoring well data collected prior to on-site mechanical de -watering and excavation below wet season groundwater level. Submittal of such wet season and dry season monitoring well data may be delayed until issuance of the first mining permit renewal or within 1 year of the issuance of the initial mining permit. Estimated depth, thickness, and extent of the confining layer (e.g. Hawthorne group) in the general area of the project site, and maximum depth of proposed project excavation and well drilling activities. Evaluation of the cumulative groundwater impacts on adjacent wells, wetlands, and vegetation from mining or excavation operations that exist or are proposed in the vicinity of the subject mining proposal. Hydrology model run outputs for the milling operation with assumptions, summary, and conclusion. in addition, model run outputs shall be submitted that predict the post -reclamation groundwater and lake levels and shall include assumptions, summary, and conclusion. Recommendations from the professional engineer or geologist to the site plan project engineer on mining design, operation, and monitoring that ensure no adverse impacts on adjacent wells, vegetation, surface waters, and wetlands. 1. Along with the hydrology report, the applicant shall submit a $10,000.00 deposit (or such deposit amount established by Resolution of the Board of County Commissioners as may be amended from time to time) to be used by the county to cover the cost to hire professional services to rev'ew and comment on the hydrology report. Once professional serves are paid, the county shall return any funds remaining on deposit to the applicant. *(e) Written clescription of how the site plan incorporates the design recommendations contained in the hydrology report and applicable items from the county's list of mining best management practices (burps). 1. A clescription, noted on the site plan and stormwater management permit plans, stating how the proposed mining operation will satisfy state and federal groundwater impact regulations and standards. 2. The date, noted on the site plan, a copy of the hydrology report was sent to the SJRWM D. *(f) Soils test data, if any, required by the Department of Health (DOH) as a result of the county site plan pre -application conference process. The DOH may require soils testing if it determines that site conditions appear to have pollution indicators for soil contaminants regulated by 62-777 Florida Administrative Code. (g) The location, depth, characteristics, and condition of all existing wells on site. (h) The distance from the excavation area(s) to the nearest existing or proposed city or county surficial aquifer public water supply well. *These items may be submitted after initial review by the Technical Review Committee (TRC).
