QUETTA: The Sui Southern Gas Company limited (SSGC) has decided to shut down all CNG stations in the provincial capital for 15 days from Tuesday due to low gas pressure. SSGC officials said that during the current winter season Quetta required 230 million cubic feet per day of gas which it was not able to receive from Shikarpur presently. The authorities therefore decided to shut down all the 17 CNG stations in Quetta for 15 days.
