the rate is measured after regasification of the liquid natural gas and any other processing required on the recovery of the gas from storage;
“storage capacity” means the capacity of the facility for storage of liquid natural gas.
(5)The storage capacity of an LNG facility is to be measured as if the gas were stored in regasified form.
