Helping to Develop Integrated Environmental Solutions
Sargent & Lundy provides integrated environmental solutions to minimize your costs to comply with regulations by considering the impacts to each site as a whole. Our team consists of chemical engineers who understand the process technologies and regulatory specialists with expertise in compliance and permitting. Environmental services we provide include:
One of the biggest challenges utilities face is planning for compliance, given multiple environmental regulations, regulatory uncertainty, and site-specific requirements. Whether for a single unit or for an entire fleet, compliance planning requires in-depth understanding of power plant operations, regulatory requirements, and technologies available for compliance. Sargent & Lundy’s environmental services team consists of regulatory specialists who focus on reviewing and understanding the regulations as well as process engineers, who focus on understanding the technologies that reduce air and water emissions. We draw upon extensive experience retrofitting air quality and water quality control systems at existing power plants and can help you achieve compliance evaluations with realistic capital and O&M costs and account for site-specific limitations. Additional information on example projects and services related to compliance planning is available below.
In addition to our engineering capabilities, Sargent & Lundy provides comprehensive environmental permitting and licensing services for power generating facilities, transmission lines, substations, and other power-related projects. On behalf of our clients, we have prepared permit applications for and successfully obtained the key types of permits and approvals necessary to site, construct, and operate power-related facilities. Recent projects include:
- Major source air construction permits for new natural gas combined-cycle power plants air permits for new simple-cycle combustion turbines and gas-fired reciprocating engines
- Permits required to support coal-to-natural gas conversion projects
- Operating permit modifications for the installation of air pollution control systems
- Wastewater treatment and discharge permits
- Local zoning approvals
- Building permits
A benefit you will experience by using Sargent & Lundy for both detailed design and permitting support for projects is that a dedicated permit specialist is assigned to the engineering design team, eliminating information exchanges that occur between engineering companies and environmental consulting firms. In addition, our technical knowledge base supports establishing permit limits that include realistic margins to account for variations in operation, including startup, shutdown, and malfunctions.
Emission Reduction Technology Experience
Sargent & Lundy is an industry leader in emission reduction retrofit projects both for air quality and water quality compliance. Our chemical engineering staff provides the process expertise to select the right technology for compliance and that it is designed to achieve emission targets while minimizing capital and O&M costs. We have extensive experience and knowledge in evaluating, specifying, and retrofitting air quality and water quality technologies including:
- Acid gas emission reduction technologies, such as wet and dry flue gas desulfurization and dry sorbent injection
- NOx reduction technologies, such as selective non-catalytic reduction and selective catalytic reduction
- Particulate matter reduction technologies, such as electrostatic precipitator upgrades and fabric filters
- Mercury reduction technologies, such as activated carbon injection, fuel additives, and FGD additives
- Carbon dioxide reduction technologies, such as carbon capture and sequestration and oxycombustion
- Makeup water treatment technologies, such as reverse osmosis, demineralization and desalination systems
- Raw water treatment technologies, such as clarification and filtration
- Wastewater treatment technologies, such as physical / chemical and biological systems
- Zero-liquid discharge technologies, such as byproduct fixation and stabilization, spray dryer evaporators, and evaporation and crystallization of wastewater
Sargent & Lundy’s experience retrofitting environmental technologies as part of an EPC team or by providing balance-of-plant detailed design and owner’s engineering services provides us with a varied perspective and thorough understanding of these projects from conceptual design through compliance testing.
Water Resources Consulting Services
Sargent & Lundy’s Water Resources Group provides services in hydrology, hydraulics, and coastal engineering to help clients find the optimal solution for all types of water-related projects. A multi‐disciplinary team with experience uniquely specialized in power plant projects can achieve the quality water resources services for risk assessment, site evaluation, regulatory compliance, and detailed design that support complex engineering projects. The end results provide our clients both cost-effective and risk‐managed solutions.
Sargent & Lundy provides water resources consulting services for hundreds of electric power plant projects with diverse challenges and in a variety of locations. Depending on each client’s needs, we provide water resources consulting as a stand‐alone project or as an integral part of our full scope of services from planning and detailed engineering design to plant operation. Our broad range of experience is based on using present‐day methodology and tools, allowing Sargent & Lundy’s Water Resource Consulting services to be uniquely qualified to solve technical challenges and manage water‐related risks specific to power plant design and construction.
