Mount Polley Mining Corporation

Прорыв хвостохранилища Mount Polley нельзя свести к одной ошибке. Независимая комиссия нашла пусковой механизм в слабом ледниково-озёрном слое основания, главный инспектор — в более широкой системе эксплуатации и надзора, генеральный аудитор — в дефектах регуляторной системы. Их выводы пересекаются, но не взаимозаменяемы. Обвинения 2024 года по Закону о рыболовстве остаются обвинениями.

The Mount Polley tailings-storage-facility breach was not a mystery that can be reduced to one missed reading, one rainy season, or one regulator who failed to spot an obvious crack. The independent engineering panel traced the initiating failure to a weak glaciolacustrine foundation layer that had not been adequately characterized and to a design that did not account for how that layer would behave under the embankment. The Chief Inspector of Mines accepted a closely related physical sequence but examined a wider operating system: steepened geometry, an unfilled toe excavation, water and beach management, changing engineers of record, corporate oversight, and the regulator's reliance on pro
