Low pressure conditions are defined by API as an operating range of just above atmospheric to 15 psig. The TANKS model uses equations developed under atmospheric conditions and is not programmed to estimate emissions from low pressure tanks. However, you may use API Bulletin 2516, Evaporation Loss From Low-Pressure Tanks, to determine if your storage pressure is sufficient to prevent standing storage losses from the material stored. Working losses can be calculated as a percentage of the throughput.
