SF6 GAS

The LEED NC V3 project we are working on has an electric system that requires an Electric Substation that has cells of medium tension which are protected with SF6 gas (sulfur hexafluoride), which causes the greenhouse effect. We’re wondering if this would fall under the purview of EA P3 : Fundamental Refrigerant management, or if, given the characteristics of the system (it is located far away from the users of the building, and won’t have any gas seepage) it is not considered under this prerequisite. If we are not complying with the prerequisite- any ideas on how we might be able to resolve this issue? Any ideas or experience in this area would be greatly appreciated.
