Water Use and Environmental Permitting
E Sciences assisted Florida Mining Corporation with preparing applications and obtaining various permits for a 1004-acre lime rock mine in Sumter County. Permitting activities included an Individual Water Use permit from the SWFWMD, NPDES Industrial Wastewater Discharge permit from the FDEP and an FDEP Environmental Resource Permit, as well as USACE and County permits.
As part of this project, E Sciences staff of engineers, hydrologists, and hydrogeologists designed a water management program to evaluate and manage surface water and ground water systems. The project team prepared an environmental assessment and monitoring program to evaluate the impacts of the limestone mining operation on the natural environment. The project team also developed mitigation measures for direct impacts and hydrologic influences on wetlands. E Sciences assisted the client with identifying environmental issues and project permitting efforts with SWFWMD, FDEP, USACE and Sumter County, including:
- Implementing a quality assurance and quality control plan for ensuring the quality of the data, models, assessments and reports generated as part of this project.
- Preparing computer models to simulate dewatering of active mine pits and mounding associated with on-site water storage.
- Designing and implementing an environmental monitoring program to collect surface water and ground water data.
- Evaluating effects of dewatering and mounding of surface water on local hydrologic systems. This program included installing and monitoring a ground water, surface water and ecological monitoring network.
- Preparing monthly and annual environmental monitoring and assessment reports discussing trends in surface and ground water.
- Preparing annual wetland assessment surveys to document baseline and future condition of jurisdictional wetland and to evaluate the effects of the mining operation on these systems.
- Performing water budgets, water quality analysis, flood plain studies and flood frequency analysis, and calibrating and executing hydrologic modeling.
- Designing water control structures.
- Assessing and performing ecological studies and restoration efforts.
- Designing on-site wetland restoration, enhancement, and creation areas.
E Sciences also assisted this client with meeting the requirements of the Clean Water Act by obtaining a general water use permit and NPDES industrial waste discharge permit. These permits enabled the owner to perform dewatering activities as part of lime rock mining operations. E Sciences prepared a groundwater flow model to simulate dewatering of active mines pits and mounding associated with pumping a portion of this mine water to former mined out pits on site. We designed and implementing an environmental monitoring program to evaluate what effects dewatering and mounding had on local hydrologic systems. This program included a network of piezometers and staff gauges to observe and document surface water and groundwater levels. E Sciences prepared monthly and annual environmental monitoring reports discussing trends in the water levels, and determining if increases and decreases of local water levels are the result of mining activities or due to changes in climate conditions. Services included preparing annual wetland assessment surveys to document baseline and future conditions.
