Overview of Air Quality Management and Air Pollution Control

Geosyntec develops strategic approaches to complex, multi-pollutant emission issues. Geosyntec develops strategic approaches to complex, multi-pollutant emission issues.

The evolving nature of government regulations for air quality and emissions requires companies to plan for and adhere to comprehensive monitoring, testing, emissions control, record keeping, and reporting requirements.

Successfully navigating this complex regulatory environment is a challenge for companies that must ensure compliance while also minimizing operational and financial impacts.

Geosyntec's comprehensive understanding of laws and regulations pertaining to air quality paired with our expertise in state-of-the-practice emissions control and monitoring technologies allow us to provide our clients with innovative and cost-effective solutions for their air quality compliance challenges. Our air quality 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. We are experienced in:

Air Permitting

We provide our clients with unique solutions that often result in the avoidance of major source permitting requirements, like Prevention of Significant Deterioration (PSD) or nonattainment area New Source Review, due to our extensive knowledge in operating permit programs; providing permitting assistance to our clients under federal, state, and local air construction; and proven record in crafting strategic approaches to air quality challenges. When avoidance is not an option, our team of air dispersion modelers and control technology experts have the experience necessary to respond to the challenges associated with major source permitting requirements, including performing control technology evaluations (e.g., Best Available Control Technology (BACT) and Lowest Achievable Emission Rate (LAER)) and ambient air impact analyses (e.g., National Ambient Air Quality Standards (NAAQS), PSD Increment, and state Toxic Air Pollutant demonstrations).

Air Compliance and Reporting

With federal, state, and local air quality regulations in a constant state of fluctuation, maintaining compliance can be a constant struggle and burden on businesses. Our air practitioners' experiential understanding of policy, regulation, and drivers results in effective and efficient compliance solutions for our clients so that they can address reporting challenges and remain in compliance without concern. Working with clients, Geosyntec practitioners provide the necessary framework to implement comprehensive environmental management strategies that allow facilities to meet compliance and reporting requirements. Among the compliance programs we have helped design include those governing emission inventory reporting; Title V annual and semi-annual reporting; greenhouse gas (GHG) reporting; and deviation reporting.

Air Quality Control Device Evaluations and Optimization

Our practitioners frequently evaluate air pollution control devices and advise clients on potential avenues for optimization that meet emission standards and minimize operational costs. Our project portfolio includes combustion management and tuning for boilers, thermal oxidizers, and other combustion devices. We have expertise in the measurement of complex pollutants, such as mercury and sulfur trioxide (SO3), in addition to standard control device emission measurements and U.S. Environmental Protection Agency (EPA) test methodologies. Geosyntec offers installation of state-of-the-practice hardware and software that utilizes cross-duct laser technology for continuous monitoring of ammonia (NH3) and SO3. We also provide Continuous Emission Monitoring System (CEMS) selection and operational assistance, data management, and equipment maintenance to provide maximum equipment uptime and effective data collection and analysis.

Advancing the State of the Practice

The expertise in process and air pollution control technology design that our practitioners have enables us to develop strategic approaches to complex, multi-pollutant emission issues and provide our clients with a balanced approach to their plant operations. Within the electric power industry, Geosyntec practitioners designed strategies that reduced the amount of coal required to produce energy through improvements in fuel use, waste generation systems, and air pollution controls. Optimization of air pollution controls, such as selective catalytic reduction or thermal oxidizers, can result in substantial fuel savings as well as and improved control device performance.

Geosyntec practitioners frequently collaborate with colleagues at EPA, the U.S. Department of Energy (DOE), the Electric Power Research Institute (EPRI), and other organizations on new strategies for reducing impacts to air quality, such as NOx control, mercury capture, scrubber optimization for heavy metals, catalyst selection and optimization, and plume opacity mitigation. Through additional research, our experts have developed emission measurement methodologies that enable pollutant-specific measurements under complex operating conditions.
