Does this Critical Water Level apply only to the Pit?

No. Pumping and treating of Pit water must begin when the 5,410-foot level is reached at ANY of the water-level monitoring compliance sites on the Hill, in what is called the East Camp. These sites include the Anselmo, Granite Mountain, Kelley, Belmont, and Steward mine shafts, as well as several other monitoring wells established to the south and the east of the Pit.

Presently, the water level at these sites is about 20-40 feet higher than the level in the Pit. So, the 5,410-foot level should be reached sooner at these sites than in the Pit, which means water pumping and treating would begin that much sooner.
