Site 2 - (60
E 50’ to 60E 58’ N - 69E 39’ to 69E 56’ E)
Site 2 is located on the
right bank of the Irtysh River, 30 km from its confluence with the Ob.
Its geology and hydrology is similar (but not identical) to Site 1. To the east of the Irtysh floodplain is a terrace that includes many lakes,
tributaries of the Irtysh, sphagnum marsh areas, and pine/birch forest. The soil is sandy-loamy of two types: podzol in well-drained areas and peat/permafrost in badly drained areas. This area was selected because it is not scheduled for
development in the near future, although is does contain oil deposits and may be developed later.
Site 3 - (61
E 16’ to 61E 24’ N - 70E 19’ to 70E 36’ E)
Site 3 is located to the northeast of Site 1 on the right bank of the Ob River. This site was selected for three reasons. First, it could be developed in the near future (3-5 years). Second, it contains a region of high economic value–the Balanskaya River is a major fish overwintering site.
That means that the fish concentrated in the river during the winter are at high risk from oil spills.
Third, it will give an opportunity to test the risk assessment algorithms using multiple sites (e.g. if
Site 3 has an oil spill, then what happens to Site 1 which is downstream from Site 3).
