Tennessee declared an Imbalance Warning Monday to enhance its operational flexibility to manage high imbalances in Zones 5 and 6. The warning requires delivery point operators in those zones to keep actual daily takes out of the system equal to or less than scheduled quantities regardless of their cumulative imbalance position, and receipt point operators to keep actual daily receipts into the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position.

Florida Gas Transmission (FGT) kept an Overage Alert Day for market-area customers that was implemented last Thursday in place through Sunday before ending it Monday. FGT also had begun maintenance last Tuesday in Zone 3 at the Gulf South/FGT Mobile Bay and SESH [Southeast Supply Header]/FGT Mobile Bay interconnects. It was scheduling up to 150,000 MMBtu/d on the lateral from Tuesday to Thursday last week, and said the lateral had normal operations Friday through Sunday. Receipts of around 350,000 MMBtu/d are being scheduled on the lateral for now, but it will wind up the work with no volumes being scheduled Friday through Sunday (Aug. 12-14). See the bulletin board for a list of other meters that may be affected.

Gulfstream canceled Sunday a low-linepack Action Alert that began Friday.

Anticipating high demand on the east end of its system, Southern implemented capacity allocations Monday until further notice for the Savannah Line and Cypress Line groups.

ANR reported beginning unplanned engine repairs Sunday at Bridgman Compressor Station along its Michigan Leg South, saying this will total St. John west-to-east capacity by 265 MMcf/d (leaving 1,030 MMcf/d available) until further notice. Based on current nominations, ANR said it anticipates that the reduction may result in curtailment of IT and Firm Secondary nominations.

Tennessee said the Venice Louisiana Transport meter will be shut in while it conducts pigging operations between South Pass 55 and Station 527 from Tuesday through Sunday. Customers producing into the 26-inch diameter 527A-100 Line upstream of station 527 should expect fluctuations in pressures and a possible suspension of flow to facilitate liquids handling following these pigging operations. The work had previously been scheduled for Monday through Saturday this week.
