Citing forecasts of 90-degree weather in Florida and falling linepack, Florida Gas Transmission issued an Overage Alert Day for market-area customers Thursday. The tolerance for negative daily imbalances was set at 25%. FGT said it would not interrupt previously scheduled ITS-1 service in the market area for Thursday’s gas day.

Columbia Gas has waived the Maximum Monthly Injection Quantity (MMIQ) for April of 15% of Storage Contract Quantity (SCQ), saying it will allow up to a 20% level. It added that the Maximum Daily Injection Quantity (MDIQ) for April was not waived unless specifically posted each day in the bulletin board’s Capacity Postings notices. Unless specifically waived, the MDIQ for April is 1/25th of a shipper’s 15% SCQ level, the pipeline said.

Transco said it will be completing anomaly repair work on its mainline downstream of Linden, NJ, on Saturday as scheduled (see Daily GPI, April 20). Effective for Sunday’s gas day, Transco will allow up to 200,000 Dth/d of IT and Secondary Firm service through the Linden constraint point and will return the NUI Erie Street meter station to service.

Questar reported gas quality issues at its Price Dew Point facilities, saying analysis of the gas composition has detected sulfur compounds that violate the pipeline’s tariff requirements. Based on extensive gas sample testing and physical inspection of receipt points between Fidlar Station and Price, Questar said, it has been determined that the sulfur compounds “are the result of point operators improperly treating their gas volumes prior to receipt by Questar.” The pipeline added that new testing procedures are being implemented, including new sulfur monitoring equipment to identify and track the sources of the sulfur compounds. Questar said it “strongly recommends that all point operators between Fidlar Station and Price review their operations with respect to gas treating…” As Questar identifies point operators with sources of sulfur compounds, it will deny nominations “until the operator has fully demonstrated that it has resolved the gas quality issue” and the source complies with the tariff specifications.

Gulf South also reported gas quality issues, saying that unless they are corrected, it will shut in the Goodrich (from NGPL) and Goodrich (from Enbridge) interconnects on its West 30-inch diameter transmission line at the start of Friday’s gas day. Gulf South said it will confirm nominations at those points to the extent there are sufficient displacement nominations in place to net each of the affected locations to zero. However, the pipeline added that it will not confirm nominations “in excess of displacement nominations based on the interconnecting parties’ confirmation reductions.”
