Produced water tanks - Store water separated at wellhead; emissions include breathing losses (i.e., normal evaporation of liquid in a tank) and working losses (i.e., evaporation due to agitation from activities such as filling the tank)
Crude oil and condensate tanks - Store crude oil or condensate at a well pad or central tank battery prior to transfer to a refinery; emissions occur from breathing, working, and flash losses (i.e., evaporation when produced liquid is exposed to a temperature increase or pressure decrease, such as when transferred from separators to tanks)
