Efficient, Responsible Management of Coal Combustion Residue

In January of 2008, Arrowhead Landfill received approval from the Environmental Protection Agency to accept special waste resulting from a clean-up or remediation effort under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Within a year of that designation Arrowhead landfill was being considered to handle millions of tons of Coal Combustion Residue (CCR) that needed to be remediated and properly disposed. After State of Alabama issued appropriate approvals, Arrowhead was selected to handle and safely dispose of over four million tons of Coal Combustion Residue (CCR) from a remediation effort more than 450 miles away.

The process included the management of up to 120 railcars a day. Each rail car was emptied, cleaned and decontaminated before returning to the remediation site. Arrowhead developed and fabricated several specialty pieces of equipment on site to aid in the unloading and cleaning process. After each railcar was emptied, the CCR was transported via off-road truck to the lined landfill cell located two miles away and properly disposed.

A comprehensive environmental monitoring program was put in place to ensure safety. Some of these processes included the installation of air quality monitoring stations near the landfill and adjacent rail lines to monitor particulate matter, the installation of additional groundwater monitoring wells, and the inclusion of a storm water runoff control system in the railcar unloading area.

Arrowhead landfill, with its partner companies, custom designed the safe transportation and unloading system for the CCR and guaranteed the safe disposal of one of the largest emergency responses to a CCR spill in the United States. This remediation and disposal project was a 24-hour-a-day operation that lasted over 17 months. Arrowhead serviced a total of 39,760 rail cars, which held more than 4 million tons of CCR.
