Trihydro stands out as a leading engineering and environmental consulting firm in Oklahoma, not just for our extensive experience dating back to 1984, but for our approach. We view each project as a collaborative partnership, working closely with our clients to develop tailored solutions that address their specific project needs.
Trihydro has team members based throughout Oklahoma, with additional resources in neighboring states who are cross-trained and available to assist with projects. Our clients benefit from the extensive resources and broad expertise of a large firm, while also enjoying the personalized attention and responsiveness of a smaller firm. Our team of professional engineers, geologists, scientists, and regulatory experts is adept at turning a strategic vision into a practical plan or design and seeing it through to project delivery.
Our history of working in Oklahoma allows us to leverage our in-depth knowledge of local regulations and environmental challenges. Our strong relationships with federal, state, and local regulatory agencies, including the Oklahoma Department of Environmental Quality (ODEQ), Oklahoma Corporation Commission (OCC), and Oklahoma Water Resources Board (OWRB), allow us to navigate complex compliance requirements effectively. As environmental regulations continue to evolve, partnering with a firm that stays ahead of the curve is crucial. Trihydro is your trusted partner to find solutions to these challenges and achieve your project goals.

Air Quality Compliance
Air quality regulations are some of the most complex and challenging of all the environmental regulations that exist today, including in Oklahoma. Since the passing of the Clean Air Act (CAA) Amendments of 1990, there has been an evolution of regulations aimed at reducing air pollutants (e.g., SO2, NOx, CO, VOC, PM, PM10, PM2.5, GHGs). Operators in Oklahoma are often challenged in keeping up with the volume of evolving regulations at the federal, state, and local levels to institute best practices and remain in compliance.

Environmental Site Assessment and Characterization
A significant component of managing environmental liability involves understanding environmental conditions through thorough assessments. If impacts are suspected in site soil, groundwater, surface water, sediment, indoor air, or soil vapor, Trihydro has a broad range of experience to assist with the characterization of industrial and abandoned properties with legacy environmental issues.

Emerging Contaminants
Emerging contaminants (ECs) enter the environment in numerous ways, such as from industrial discharge or consumer product use, and are found in groundwater, surface water, soils, and air. Once introduced to the environment, ECs behave differently and carry varying levels of risk, creating complexities in detection, fate and transport modeling, results interpretation, and remediation. Emerging contaminants pose additional challenges due to evolving technical and regulatory understanding.

Carbon Capture, Utilization, Storage (CCUS)
Fossil fuel producers, users, and other greenhouse gas emitters are actively seeking ways to reduce and manage emissions due to concerns about climate change. One strategy that is gaining momentum is carbon capture, utilization, and storage (CCUS). The Federal IRS tax credit program, under Section 26 U.S. Code § 45Q, provides lucrative incentives to encourage the adoption of CCUS initiatives. The increasing prominence of CCUS initiatives signifies a paradigm shift in how industries approach environmental stewardship.
