In 2000, Hydro implemented an Environmental Site Assessment (ESA) program for all properties it owns or operates. The process followed is illustrated in Figure 6.

The objectives of the ESA program are to:

  • evaluate the potential for environmental contamination;
  • undertake sampling to characterize and delineate any contamination;
  • assess the potential risks and liabilities associated with any contamination identified;
  • identify sites requiring monitoring or remediation; and
  • develop and implement remediation programs when necessary.

Since the inception of the ESA program in 2000, the sites of all rural isolated generating stations have been assessed at least to a Phase I level. These are the sites with the highest environmental risk based on the throughput of potential contaminants. The program will now focus on facilities with less hydrocarbon storage capacity, and therefore, potential risk such as terminal stations, material storage yards and line depots.

In 2005, throughout Hydro’s system, 11 Phase I ESAs were completed; 9 Phase II ESAs, complete with Risk-Based Corrective Action (RBCA); and 10 RBCA were undertaken based on Phase II ESAs completed during previous years. This included ESA work undertaken at CF(L)Co.

Table 3 shows the ESA work that was accomplished in 2005 and future plans, if any, for the site.
