John Seymour is a Senior Principal Civil Engineer based in Illinois with over 30 years of experience focused on site remediation, deep foundation engineering, and construction management. His clients include major electric utilities based in the Midwest and Mid-Atlantic states as well as PRP groups.
John's practice focuses on all aspects of the permitting, design and remedy implementation of Superfund (CERCLA) and RCRA projects. He has led many projects and provided professional consulting services in the areas of engineering design, project management, site characterization, feasibility studies, bench and pilot studies, civil and geotechnical design, construction quality assurance (CQA), expert witness, owner's representative, and the operation and maintenance of CERCLA and RCRA remedial systems.
To better assist his clients, John develops cost-effective alternatives to conventional solutions that take advantage of the latest technologies and innovative applications of existing technologies while achieving regulatory acceptance. For example, he demonstrated that changed groundwater conditions allowed elimination of the geomembrane in the cover system design at a CERCLA site that earned regulator acceptance and saved his client a large amount in construction cost. At another CERCLA site, he developed a direct groundwater discharge system that earned regulator acceptance and helped his client realize significant savings when compared to the initial extraction remedy required by the agency.
As a leader in the design of new or expanded coal combustion byproduct (CCP) facilities for the electric utility industry, John routinely provides innovative solutions for disposal. As project manager for the design of a CCP landfill in West Virginia he designed the lateral and vertical expansion of a disposal site using a reinforced soil slope (RSS) retention system. At coal-fired power plants in Ohio and Michigan, he completed feasibility studies to assess the potential to develop a new flue gas desulphurization (FGD) waste landfill over an existing fly ash disposal area. John is also completing a redesign of the embankments of a large coal ash pond to improve their slope stability and to reduce maintenance.
To advance the state of the practice, John has authored several peer-reviewed technical papers, led training panels, and provided technical presentations to industry groups in the areas of waste containment, vertical landfill expansions over very soft subgrades, mixed waste, quality control/quality assurance at contaminated sites, and drilled piers.
