Citing limited operational flexibility and mild weather, Tennessee said a systemwide OFO Action Alert will take effect Saturday for all Balancing Parties. Penalties will apply to all such parties who exceed a positive daily imbalance tolerance of 2% of scheduled quantities or 500 Dth, whichever is greater. “In the event the OFO Action Alert is not sufficient to maintain the operational integrity of the system, Tennessee may issue a Critical Day or an OFO Balancing Alert,” the pipeline said.

Pacific Gas and Electric ended a systemwide high-inventory OFO Monday on its California Gas Transmission System that had been in effect for the previous two days, but it reinstated one with a 9% tolerance for positive imbalances for Tuesday.

Citing limited operational flexibility and mild weather, Tennessee issued a systemwide OFO Action Alert that will take effect Saturday for all balancing parties. They are required to maintain an actual daily flow rate not exceeding 2% of scheduled quantities or 500 Dth, whichever is greater, for overdeliveries into the system and undertakes from the system, Tennessee said.

Pennsylvania’s county conservation districts would reclaim authority over erosion and sediment control in the Marcellus Shale under legislation that Republican state Rep. Karen Boback said she will introduce in the House next month.

New Pennsylvania wastewater treatment rules, which apply to gas drillers in the Marcellus Shale, are now in effect, the state’s Department of Environmental Protection (DEP) said.

Citing limited operational flexibility to manage imbalances, Tennessee said a systemwide Imbalance Warning will go into effect Saturday and require all delivery point operators “to keep actual daily takes out of the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position. All receipt point operators are required to keep actual daily receipts into the system equal to or less than scheduled quantities regardless of their cumulative imbalance position.” If compliance is not sufficient, Tennessee said, it may take further actions, including contract- or meter-specific OFOs to maintain operational integrity.

Pacific Gas and Electric ended a systemwide Stage 2 high-inventory OFO Sunday after it had been in effect for only the previous day, but it then issued a new high-inventory OFO for Tuesday with a 9% tolerance for positive daily imbalances.

Florida Gas Transmission ended Saturday an Overage Alert Day that had been in effect continuously since July 8.

Pacific Gas and Electric did not extend a Stage 2 high-inventory OFO beyond Friday.
