The OLD style geothermal plants simply vented the leftover steam and gasses into the open air. The new style plants are closed systems that even inject the leftover steam and gasses back into the ground, near where they came from. There are no noxious gasses that are spewed out, unless they have a leak and they can shut down almost immediately. They have multiple air monitoring systems. They are doing it right.
