Noting forecasts of sub-zero cold for much of Wisconsin Wednesday night and Thursday, ANR declared an Extreme Condition effective at 9 p.m. CST Wednesday until further notice. ANR said the action lowers its “Swing Percentage” (essentially, negative imbalance tolerance) from 10% to 5%, and it is not allowing any Unauthorized Overrun under Rate Schedules FTS-1, FTS-2, FTS-3, STS and ETS. The pipeline also asked that all receipts and deliveries in Wisconsin, excluding ETS and FTS-3 services, be at a uniform hourly flow rate over a 24-hour period.
