Citing the effects of Hurricane Isabel, Columbia Gas said Friday its markets in southeast Virginia were “taking gas at abnormally low levels” and the condition might require issuance of an OFO. Columbia said its ability to receive gas into Market Area 34, “specifically at the Emporia interconnection with Transco,” was very limited. Market Area 34 was already subject to Critical Day restrictions (see Daily GPI, Sept. 10). To avoid an OFO, customers were asked to minimize receipts into Market Area 34, especially at Emporia, where zero non-firm receipt capacity was posted. “Customers should attempt to verify the existence of their actual market prior to scheduling deliveries into Markets Areas 33 and 34,” the pipeline continued. See the bulletin board for actions that Columbia took to protect system integrity and other details.
