The term facets has many definitions as does the term rehabilitation. When these terms are linked with the issues identified by members of this Association in the survey taken in 1985, the spectrum becomes very broad. These issues, or facets, range from toxic waste sites to land use planning to ecosystem renewal. In all cases, they depict various concerns and point out the need for subsequent activities for the reclamation, rehabilitation and restoration of our environment. Industries and governments are not exempt from these issues and activities, most of which are regulated by environmental legislation. At Ontario Hydro, it is not a case of what to do, but more one of how to do it to comply with environmental requirements. In order to undertake any project, some research is required. Sometimes this means breaking new ground, such as in reclamation to establish vegetation on fly ash or on spoil piles excavated from new generating station sites. Abandoned gravel pits on rights-of-way must be rehabilitated through revegetation and sometimes landscaping to assist in protecting the security of the lines. The greatest activity, however, is in the area of restoration. Restoration is required because of Ontario Hydro's land based activities in forested and agricultural lands and as a result of natural occurrences. Through the interaction of water with the components of the landscape unit, Nature herself, or Ontario Hydro operational activities, many erosion problems must be dealt with and corrected. Other land based restoration problems stem from various sources, and involve many different stages. These may be pipelines utilizing right-of-way lands, adjacent subdivisions and their drainage problems, construction, and acts of nature. Each has its own unique solution, and each is one of the facets of rehabilitation undertaken by Ontario Hydro and other utilities across Canada.
