Karst / Sinkhole Services
GER is experienced in carbonate rocks and the mitigation of hazards associated with karst development (sinkholes). We have provided karst analysis and engineering for many projects, including projects requiring foundation stabilization, slope stabilization and sinkhole stabilization.
- Identify and inventory geological, hydrological and karst features
- Pre-design subsurface investigations
- Evaluate impact of karst features on the local environment
- Develop work plans for geological, hydrological, water measurement and dye tracing work
- Report findings and conclusions with maps, drawings, graphs and tables
MINERAL RESOURCE EVALUATION
GER can assist you with an initial mineral resource evaluation, whether you are wanting to start a gravel, clay or limestone mining operation. With our extensive knowledge of the geology in the state of Missouri and through geologic literature reviews, GER will help evaluate your anticipated mineral resource.
Mineral Resource Evaluation Services
- Limestone, Sand & Gravel Mineral Resource Evaluations
- Metallic Mineral Closure Plans
SURFACE MINING & RECLAMATION
GER provides and assists clients with the preparation, submittal and approval of the Missouri Department of Natural Resources (MDNR) surface mining permits, air operating and construction permits, and National Pollutant Discharge Elimination System (NPDES) stormwater permits for development of open-pit quarry operations. Other services include the preparation of Stormwater Pollution Prevention Plans (SWPPP) and a Spill, Control, and Countermeasures (SPCC) plans for your surface mining operation. For existing surface mining operations, our experienced staff will work with you to release the bond liability of reclaimed land, reclamation variance requests, alternate land use change requests, and request approval of permit revisions involving mined and reclaimed ground near the Solid Waste Management Area (SWMA) in accordance with Missouri Land Reclamation Program (MLRP) regulations.
Surface Mining & Reclamation Services
- Land Reclamation Permit Compliance Evaluation
- Permits, Expansions, Transfers & Amendments
- Bond Release Review & Applications
- Closure & Post Closure Plans
SHOOTING RANGE CHARACTERIZATION & RECLAMATION
Shooting range characterization and reclamation is just another specialized service we provide at GER. Our services include lead determination/delineation of shooting range cumulative shot-fall areas, site characterizations and sample collection, and the identification of lead reclamation and chemical stabilization areas.
Shooting Range Characterization & Reclamation Services
- Site Lead Assessment Plans
- Site Lead Characterization
- Lead Remediation & Reclamation
Shooting Range Complex Renovation:
Developed construction documents and drawings to facilitate contractor bidding for removal of metals at the Perry Memorial Conservation Area, for recycling, chemical treatment of soils impacted with metals, beneficial reuse of impacted soils, and renovation of the site to achieve risk-based target levels for lead and other metals. Final plans and details were provided for construction and post treatment sampling recommendations in accordance with applicable regulations.
Karst / Sinkholes:
Conducted sinkhole and flooding evaluations in accordance with the City of Nixa Code of Ordinances and Technical Specification Manual. The 24-acre tract was proposed for development of a residential subdivision. A total of 7 sinkholes were identified, with three possible karst features. The evaluation delineated sinkhole development features, setbacks, buffers, and flood elevations. The sinkhole evaluation also included flood prevention requirements and water quality protection. Provided development recommendations of non-karst impacted areas of the site.
Limestone Mining Plan:
Provided services including the preparation, submittal and approval of the Missouri Department of Natural Resources for a surface mining permit, air operating and construction permit, and a stormwater discharge (NPDES) permit for the development of an open-pit limestone quarry operation located in Cape Girardeau County, Missouri. Services also included the preparation of a Stormwater Pollution Prevention Plan (SWPPP) and a Spill, Control, and Countermeasures (SPCC) plan.
