Advancing the State of the Practice Geosyntec's practitioners are pioneers in site assessment and remediation. Our senior practitioners have developed and authored guidance material and courses for local, state, and national agencies and associations on remediation techniques and technologies. Working with the Interstate Technical Regulatory Council, Geosyntec practitioners taught a training course on vapor intrusion, including mitigation options for the development of vapor-impacted brownfield sites. Geosyntec practitioners also wrote the guidance document on evaluating, optimizing, or ending post-closure care at impacted sites, including brownfield sites, and developed a patented approach for sub-slab vapor migration mitigation allowing residential, commercial, and industrial development on sites impacted by vapor intrusion. Our specialists routinely collaborate with prominent national researchers from academia and government agencies to provide innovative and defensible strategies for sites with contaminated sediments. For example, we collaborated with the United States Geological Survey (USGS) to remediate chlorinated solvent-contaminated marsh sediments by applying a bioreactive mat system embedded with a dehalogenating microbial consortium, a technology Geosyntec helped develop. This project and partnership earned our client recognition as a finalist for the Service to America Medal awarded by the Partnership for Public Service. Through a collaborative research project with the University of Florida, Geosyntec professionals helped develop the FLUCL software package for the Florida Department of Environmental Protection. This software is used to calculate exposure point concentration statistics in risk assessment and was the first of its kind to contain algorithms for censored datasets. FLUCL has received endorsements from several United States Environmental Protection Agency regions and the California Environmental Protection Agency. Geosyntec scientists also pioneered the use of genetic molecular tools to characterize microbes in environmental media and are engaged in applied research and development with top academic institutions around the world, including the University of Toronto, Cornell University, and the Georgia Institute of Technology.

Government regulations for air quality and emissions continue to rapidly evolve. Companies must understand, plan for, and adhere to rapidly changing requirements including monitoring, testing, emissions control, recordkeeping, and reporting. Attaining and maintaining compliance while minimizing operational and financial impacts can be a challenge, particularly in today’s regulatory climate. Geosyntec's comprehensive understanding of air quality laws and regulations, along with our expertise in state-of-the-practice emissions control and monitoring technologies, equip us to provide our clients with innovative and cost-effective solutions for their air quality compliance challenges. Our practitioners offer clients a broad array of services, including permitting, compliance reporting, and air pollution control technology selection and optimization. Our projects routinely involve minor and major source air permitting, compliance assistance, and regulatory negotiations, as well as air pollution control equipment troubleshooting, optimization, and testing. Air Permitting On behalf of clients, we create unique solutions that often help them avoid major source permitting requirements, like Prevention of Significant Deterioration (PSD) or nonattainment area New Source Review (NSR). Relying on our extensive knowledge of operating permit programs and our experience in a broad range of industries and emissions sources, we offer clients permitting assistance that aligns with federal, state, and local air jurisdictions. We craft strategic approaches to air quality challenges. When major source permitting cannot be avoided, our air dispersion modelers and control technology experts know how to respond to challenges associated with major source permitting requirements. Geosyntec’s experts address control technology evaluations, including Best Available Control Technology (BACT) and Lowest Achievable Emission Rate (LAER) evaluations. They are also adept at understanding and conducting ambient air impact analyses, like National Ambient Air Quality Standards (NAAQS), Prevention of Significant Deterioration (PSD) increments, and state toxic air pollutant (TAP) demonstrations. Air Compliance and Reporting With federal, state, and local air quality regulations constantly in flux, maintaining compliance can be a burden on businesses. Our nuanced understanding of policies, regulations, and drivers empowers us to craft effective and efficient compliance solutions for our clients to help them address challenges and remain in compliance. Together, we develop frameworks for comprehensive environmental management strategies that help clients meet air compliance and reporting requirements. Some of the compliance programs we helped design include those governing emission inventory reporting; Title V annual and semiannual reporting; greenhouse gas (GHG) reporting; and deviation reporting. Evaluation and Optimization of Air Quality Control Devices Our practitioners evaluate air pollution control devices and advise clients to help them meet emission standards and minimize operational costs. Our project experience includes combustion management and tuning for boilers, thermal oxidizers, and other combustion devices. We also specialize in area and source measurement of complex pollutants such as mercury, sulfur trioxide (SO3) and per- and polyfluoroalkyl substances (PFAS), Geosyntec has installed state-of-the-practice hardware and software using cross-duct lasers to continuously monitor ammonia (NH3) and SO3. In addition, we can assist clients with selection of continuous emission monitoring systems (CEMS) and offer operational assistance, data management, and equipment maintenance. Continuous Emission Monitoring System Design and Ambient Air Monitoring Geosyntec has supported clients with development of comprehensive environmental management strategies, optimization of plant operations, and increasing efficiency of their air emissions control systems. This has included installation, evaluation, and enhancement of CEMS at point sources and ambient air monitoring systems for fence line or offsite monitoring. Air Litigation Support Leading law firms throughout the United States seek technical support from Geosyntec due to our expertise and credibility providing litigation support. Geosyntec provides resources for attorneys to advocate for their clients’ interests on a myriad of air subjects related to business transactions, environmental management, compliance and enforcement, toxic tort, and general litigation topics. Geosyntec’s team of senior air professionals frequently provide expert witness testimony opinion reports, claims assessments, and agency negotiations and settlement support. Advancing the State of the Practice Experts in process and air pollution control technology design, we help clients develop strategic approaches to complex, multipollutant emission issues and provide clients with a balanced approach to plant operations. In the electric power industry, Geosyntec practitioners design strategies that reduce the amount of coal required to produce energy through improvements in fuel use, waste generation systems, and air pollution controls. Optimal air pollution controls, such as selective catalytic reduction (SCR, or thermal oxidizers), can result in substantial fuel savings and decrease emissions through improved performance of control devices. Geosyntec practitioners frequently collaborate with colleagues and industry peers at the USEPA, the US Department of Energy (DOE), the Electric Power Research Institute (EPRI), the Air and Waste Management Association (AWMA), and other organizations on new strategies for reducing air quality impacts. These collaborate strategies involve NOx control, mercury capture, scrubber optimization for heavy metals, catalyst selection and optimization, and plume opacity mitigation. In addition, our experts have developed methods to measure emissions of specific pollutants under complex operating conditions which have been accepted by air agencies across the country.
