• Electric Power
• General Manufacturing
• Mining
• Oil & Gas
• Solid Waste & Recycling

Our capabilities include:

• Mine and Reclamation Planning, Design and Permitting: Trinity supports the complete life of mine, from pre-feasibility and the mine planning stages, through detailed operational planning and design, reclamation, and post-closure monitoring.  Our team of scientists, engineers and planners have expertise working on mining projects across the western U.S., assisting clients secure the necessary entitlements and approvals to advance mining projects from initial concept through permitting.
• Geologic and Mineral Resource Investigation: We provide technical investigations for sand and gravel, crushed stone and industrial mineral projects to characterize the viability of geologic and mineral resources as part of a discrete planning and permitting process, due diligence validation or technical reporting requirements under SEC regulations. Our services include subsurface analysis, geologic interpretation and modeling and pit design to produce technically sound resource and reserve estimates. Trinty’s geologists also conduct geochemical studies and drilling/sampling campaigns to assess material properties and quality considerations.  Our modeling tools include state-of-the-art programs, which can account for complex geometries, grade variations and project specific cut-offs. Trinity’s employs a multivariate approach, integrating exploratory drilling data, field mapping, and geophysical methods to characterize deposits and corroborate model interpretations.
• Hydrogeologic Studies and Water Resources: We conduct groundwater evaluations, aquifer testing, drawdown analysis, and water balance studies to support supply planning, permitting, and regulatory compliance for commercial, industrial, and mining operations.  Services also include well design, construction and development for monitoring and production wells in both alluvial and fracture flow systems.
• Contaminated Site Studies and Environmental Forensics: Trinity’s experts have extensive, practical knowledge navigating the site investigation and remedial planning for industrial sites impacted by historical releases, as well as providing environmental due diligence support related to identifying and evaluating recognized environmental conditions.  Our team has experience with chlorinated solvents, petroleum hydrocarbons, metals, perchlorate, and other priority pollutants. We prepare Conceptual Site Models (CSMs), response-to-comment documentation, and corrective action plans under voluntary and enforcement programs administered in California by the Department of Toxic Substances Control (DTSC), Regional Water Quality Control Boards, local agencies. We also conduct Phase I and II Environmental Site Assessments (ESAs), risk evaluations, and liability cost modeling for property transactions.
• Geologic Assessment: In support of the environmental review process under CEQA and NEPA, Trinity’s team routinely prepares geology and soils baseline studies, hydrogeologic evaluations, and paleontological resources assessments, along with preparation of relevant impact significance assessments.  With our team of land use planners and CEQA/NEPA experts, Trinity can align these efforts to improve study objectives, reduce time constraints and overall entitlement costs on those projects where these types of resources studies are required.
• Sustainability and Climate-Related Financial Risk Disclosure: Our experts assist clients in developing and implementing sustainability strategies to reduce their environmental impact and improve their sustainability performance, including assisting clients with managing their greenhouse gas emissions and developing strategies to address climate change risks and opportunities.
• Industrial Hygiene and Worker Safety: Trinity employs Certified Industrial Hygienists (CIH) with experience performing job hazard analysis, PPE selection, exposure assessment for chemical and physical stressors, and exposure assessment program development. Trinity staff is experienced in assessing regulation applicability and development of associated program materials needed to comply with occupational safety standards including hazard communication, lockout-tagout, respiratory protection, and various standards applicable to specific toxic or hazardous substances (e.g., silica, ionizing radiation).
