The Clean Air Act (CAA or Act) touches virtually every aspect of economic activity in the United States. It requires the U.S. Environmental Protection Agency (EPA) to establish national ambient air quality standards (NAAQS) for certain pollutants in order to protect public health and welfare nationwide. The Act provides a comprehensive set of regulations to monitor air toxins and requires major sources of air pollution to obtain detailed operating permits. The CAA also requires states to adopt enforceable plans to achieve and maintain air quality standards, and to control harmful emissions that might drift across state lines.
Other key provisions of the CAA are designed to minimize pollution increases from the growing number of motor vehicles, and from new or expanded industrial plants. The law calls for new stationary sources (e.g., power plants and factories) to use the best available technology, and allows less stringent standards for existing sources.
SCS Engineers is a leader in providing air quality services. We offer a wide variety of services to meet our clients’ air compliance and permitting needs. Our staff consists of professional engineers, chemists, scientists, and technicians experienced in understanding regulatory requirements, solving environmental problems, and providing innovative solutions. We have conducted New Source Performance Standards (NSPS)/Emission Guidelines (EG) and Title V projects at hundreds of landfills and industrial facilities, and we have strong working relationships with both industry and the regulatory community (EPA, states, and local air districts).
Our professionals have years of proven experience in environmental and risk management compliance services for CAA initiatives, including:
Control Technology Analysis
The primary air quality concern at landfills involves LFG emissions, and the main compliance tool is the Gas Collection and Control System (GCCS). The NSPS/EG rules require LFG testing and collection system installations at many sites, and they require landfill owners/operators to:
SCS Engineers offers comprehensive LFG services to help you meet regulatory compliance requirements within budget, including engineering test services, laboratory analysis, gas system design, system installation, and operations. We find that once compliance with NSPS air quality criteria is achieved, other LFG issues (e.g., lateral migration, impacts to groundwater, odor, etc.) usually begin to resolve.
Typical CAA tasks that SCS performs for landfills include:
Because of our extensive CAA experience, SCS is well-positioned to perform additional services that may be required as new air quality regulations are issued in the years ahead.
