Transportation Notes

Responding to Transwestern’s low-linepack Alert Day for the West of Thoreau area (see Daily GPI, Nov. 19), Southwest Gas issued a Stage 3 OFO for Friday. Southwest told customers to ensure that their gas usage did not exceed scheduled supplies, adding, “The daily operating window has been reduced to 0% and negative daily nominations for imbalance paybacks from Southwest to customers have been eliminated until further notice.” The OFO was due to end Saturday. Transwestern said Friday it was lifting the Alert Day because of improved linepack.
