KARACHI   - The Sui Southern Gas Company has announced the schedule for closure of compressed natural gas stations for the current week.  According to a media release issued on Monday, all the filling stations in Sindh would remain closed from 08:00 am on Tuesday to 08:00 am on Friday, for 72 hours.  This step is being taken by the gas utility to improve the line pack position across the province., which has been badly disturbed due to short supply of gas from different gas fields causing depletion of line pack and low pressure in the system,” a spokesperson for the SSGC disclosed. The SSGC regrets the inconvenience which may be caused to CNG users during the above notified 48-hour shutdown period.
