Q345. For storage tank emissions reported in Subpart Y, do you enter aggregate emissions or emissions on a tank-by-tank basis?

A345. Emissions are reported on an aggregated, facility-wide basis for storage tanks, but are split into two categories: (1) storage tanks that are not used for unstabilized crude oil and (2) storage tanks that are used to store unstabilized crude oil. The e-GGRT system does not allow for tank-by-tank emissions reporting.
