Geosyntec practitioners Paul Dockweiler, CPG; Jennifer Pretorius, PhD, PGeo; and Rick Sisson, PE, helped create two major technical reports in support of the Donlin Gold project in southwest Alaska on behalf of our client, NOVAGOLD Resources (NOVAGOLD).
Evan Cox, M.Sc. (Ontario) and Fabrizio Mascioni, R.G. (Arizona) will present at the MineXChange 2020 Society for Mining, Metallurgy & Exploration (SME) Annual Conference & Expo in Phoenix, Arizona on February 23-26, 2020.
Paul Dockweiler is a Senior Mining Geologist based in Nevada with more than19 years of experience focused on the development and start-up of hardrock mining operations.
Our clients understand environmental and occupational safety and health risk management is a vital component of maintaining overall operational excellence. Geosyntec's environmental management team builds compliance solutions, distinguishes between potential and actual environmental risks, and develops strategies to decrease energy and water utilization. Environmental and health & safety (EH&S) management system support services benefit our private and public sector clients who are committed to achieving high standards of EH&S performance and compliance. We develop documented management systems that allow our clients to identify, prioritize, and manage more efficiently the potential EH&S risks associated with their operations using a plan, do, check, act framework to ensure continuous program improvement. With a diverse portfolio of services, Geosyntec improves public and private sector clients' environmental and health and safety performance; manage risk; and reduce environmental liabilities consistent with their financial and stewardship goals. Our compliance, permitting, and auditing specialists have technical expertise across a broad range of disciplines. Accordingly, we are able to help our clients by proactively identifying compliance obligations and opportunities to improve their compliance record. Geosyntec practitioners specialize in solving complex challenges of occupational safety and industrial hygiene that affect workplace operations, staff comfort and productivity, or occupant health. Addressing such challenges involves the anticipation, recognition, evaluation, and control of known risks and emerging hazards in the workplace. Our practitioners conduct assessments using the sound scientific principles and practices of industrial hygiene, public health, and toxicology. We provide comprehensive Process Safety Management (PSM) and Risk Management Program (RMP) services to meet our clients' needs as they relate to the Occupational Safety and Health Administration's (OSHA) 29 CFR 1910.119 PSM Standard and the Environmental Protection Agency's (EPA) 40 CFR Part 68 RMP. The standards require the development and implementation of a system of procedures aimed at preventing accidental releases of hazardous chemicals from subject processes. All levels of an organization can benefit from our assistance in managing the daily aspects of its operations through development of environmental management systems, compliance programs and procedures, and regulatory research and applicability assessments. We accomplish this by implementing tools in a plan-do-check-act framework to ensure continuous program improvement.
Clients turn to Geosyntec's nationally recognized geotechnical and geological engineers to develop projects and services that efficiently use geotechnically challenging sites. We apply advanced technologies and leverage our proven practice leadership to provide clients with dependable, cost-effective solutions and customized services while meeting aggressive construction schedules.
Geosyntec offers extensive experience in hydrologic and hydraulic modeling and the use of model output for the analysis of channel modifications and stream restoration projects. We frequently apply these models for long-term watershed and floodplain management. Our practitioners have decades of experience in the evaluation of hydromodification activities, such as channelization / channel modification projects and the construction of dams. We also examine the resulting stream bank and shoreline erosion impacts of hydromodification and how it might affect in-stream and streamside (or riparian) habitats for fish and wildlife. We develop and calibrate watershed hydrologic models and floodplain hydraulic models using new and existing data sources to examine both the volume reduction and control benefits of hydromodification projects. We also conduct stream restoration and open channel analyses to assist and design stream bank rehabilitation projects and to restore tidal flow in restricted salt marsh environments. Our geomorphic studies and sedimentation/scour analyses are used to understand issues of accelerated erosion or changes to sediment supply. We apply our expertise in open channel hydraulics to perform flooding analyses, including floodplain delineation, flow monitoring, and rating curve development. Geosyntec has developed excellent surface water modeling expertise including hydrodynamics, sediment transport, water quality, and fate and transport modeling. Geosyntec's expertise includes application of SWMM, HEC-HMS, HEC-1, HEC-2, HEC-RAS, RMA2/RMA4, EFDC, QUAL2k, River-FLO2D, CE-QUAL-W2, Computational Fluid Dynamics, and other models.
