American Association of State and Highway Transportation Officials Support Coal Combustion Products Industry

                                                        AASHTO Subcommittee on Materials
                                     Seek to protect the ability to use Fly Ash in highway construction
                                                                      August 2009

WHEREAS,
AASHTO has observed the spring 2009 EPA regulatory agenda plans to issue a propose ruling regarding certain uses of coal waste, with intent to apply to landfill and surface impoundment facilities.

WHEREAS, Fly Ash is a coal combustion byproduct commonly used in highway construction applications such as bridges, pavements, and subgrades, and could potentially be designated as “hazardous waste” for disposal purposes with exception for certain beneficial uses under the proposed ruling; and

WHEREAS, Even if EPA’s proposed ruling allows for the beneficial use of Fly Ash, the stigma associated with using a “hazardous waste” material could effectively eliminate the use of Fly Ash in highway construction; and

WHEREAS, The May 2000 Federal register notice states “We support increases in these beneficial uses, such as for additions to cement and concrete products”; and

WHEREAS, The benefits of using Fly Ash in concrete to improve durability, ultimate compressive and flexural strengths, reduce permeability, and mitigation of Alkali silica reactivity, will no longer be an option for state DOT’s; and

WHEREAS, The use of Fly Ash in highway construction measurably reduces greenhouse gas emissions through the reduced consumption of Portland cement; and

WHEREAS, The use of Fly Ash in highway construction promotes recycling of a byproduct that would otherwise require disposal; and

WHEREAS, Fly Ash has been used in highway construction for many years without documented adverse environmental impacts, no research exists which conclusively provides a scientific argument to designate Fly Ash as “hazardous waste”.

THEREFORE BE IT RESOLVED, That the AASHTO Subcommittee on Materials take action to notify the EPA of the adverse impact this proposed ruling would have on the nation’s infrastructure; and

BE IT FURTHER RESOLVED,
That the AASHTO Subcommittee on Materials seeks to protect the use Fly Ash in highway construction and is against any proposed ruling that would impede its use for those purposes.
