One of the major challenges faced by power companies that
produce electricity with coal is how to handle the ash and other byproduct
materials left over after the coal has been burned. This material is commonly
referred to as coal combustion residuals (CCR). Recent events around the United
States involving coal ash storage impoundments put a spotlight on how power
companies are storing CCR. This has led to increased scrutiny and regulatory
requirements regarding dam stability and groundwater impacts for CCR ponds and
Hanson has been helping power companies manage their CCR
programs for decades and has a strong reputation in the power industry and
among regulatory agencies for its experience in this area. Hanson has
specialized experience in site evaluation, alternatives analysis, design,
permitting, construction and monitoring of CCR landfills, CCR surface impoundments,
flue gas desulphurization gypsum stacks and associated structures as well as the
beneficial reuse of CCR. Hanson’s team has helped clients with design,
permitting and construction-phase services for the closure of CCR impoundments
and other CCR disposal facilities, including environmental and hydrogeologic
impact studies, closure plans, closure implementation and long-term monitoring.
Hanson’s expertise in truck and rail
logistics has also been applied to the management of CCR materials, especially
to allow for efficient transportation for beneficial reuse.
When approaching changes to CCR management, solutions must not
only meet regulations but also be cost-effective. When one client sought a less
expensive method to handle the water used to transport its ash, Hanson
conducted an alternatives analysis. The team developed a simple solution that
met the environmental requirements and saved the client several million dollars
compared to the initial design.
Hanson is working on numerous CCR-related projects throughout
the Midwest, including closure-in-place designs, closure by removal,
anti-degradation plans, retrofitting and seismic analysis for impoundments.
Other CCR work includes rail system design for exporting materials for
beneficial reuse, landfill design and annual monitoring, groundwater monitoring
design plans and sample results analysis, pond and landfill airspace
calculations and water treatment options analysis. Hanson also provides clients
assistance in answering regulatory agency requests.
The landscape of environmental compliance is ever-changing. Hanson
has the experience and skills to help power companies navigate regulations and cost-effectively
