Reclamation of the Domtar/Canada brick quarry using coal fly ash

Technical Report:

Abstract

Two power plants in the Toronto area required disposal sites for coal fly ash in the late 1970s. A local brick quarry was recognized as a potential disposal site, since a 10-hectare area of the quarry was no longer in production and was required to be filled for reclamation. Ontario Hydro and the brick company joined together to obtain approval for the landfilling project. The preliminary site investigations included an examination of the impact of the project on local residents and the environment in terms of traffic volumes, noise levels, road dirt, airborne dust, and contamination of surface water and groundwater. Ontario Environmental Assessment Board hearings were held, with evidence presented from concerned parties. The findings from the hearings indicated that the project would have little effect on nearby residents and would improve the local environment by reclaiming usable land. Filling of the quarry began in December 1981 and continued for 5 years, after which a total of over 680,000 tonnes of fly ash was deposited. After completion, the ash was covered with a seal layer consisting of at least 1 m of clay or till compacted to structural fill standards with a 1 m thick protective cover layer to  More>>

After completion, the ash was covered with a seal layer consisting of at least 1 m of clay or till compacted to structural fill standards with a 1 m thick protective cover layer to protect the seal layer from desiccation cracking and frost heave. Material is currently being stockpiled at the site to increase the thickness of the protective layer in order to make the site self-managing. Monitoring of surface water and groundwater is still ongoing and will continue for many years. 17 refs., 24 figs., 7 tabs.}
