SEMCO Energy Gas Co. said Thursday that it is alerting customers of possible deceptive marketing tactics targeting natural gas customers in the utility's service areas. The company said it has received complaints of customers being contacted by people claiming to be marketing natural gas contracts to residential and business customers and implying they are associated with SEMCO Energy. SEMCO Energy said it does not solicit residential or commercial customers for natural gas contracts and is urging its customers to be "extremely cautious" about any personal information they provide in telephone solicitations. The utility advised customers who have questions about being contacted by someone representing SEMCO Energy to call 1-800-624-2019.Customers of the utility have the option to buy their natural gas from a third-party provider, however, SEMCO Energy said it does not solicit customers to sign up for the customer choice program. The Michigan Public Service Commission (MPSC) provides a list of all natural gas marketers licensed in Michigan on the MPSC website: http://www.cis.state.mi.us/mpsc/gas/choice.htm. The site includes a tab showing eligible customer choice marketers active in SEMCO Energy's service areas. The utility distributes natural gas to more than 400,000 customers combined in Michigan, as SEMCO Energy Gas Co. and in Alaska, as ENSTAR Natural Gas Co.

The Interior Department's Minerals Management Service (MMS) announced last week its intent to prepare a supplemental environmental impact statement (SEIS) on four Central and three Western Gulf of Mexico oil and natural gas leases sales tentatively scheduled for 2009-2012. In initiating a call for comments and notice of intent (NOI), the agency is seeking public comments on oil and natural gas leasing, exploration, development and production activities within the Central Gulf Planning Area, with particular attention to the "181 South Area." This is the initial step in the prelease process for a sale within that region. The earliest date for a sale in the "South 181 Area" would be March 2009, the MMS said. In December 2006, Congress passed and President Bush signed into law a bill that requires the MMS to make 5.8 million acres in the "181 South Area" available for oil and natural gas leasing as soon as practicable. The area is located south of eastern Alabama and western Florida. The call comments are due at the MMS by Oct. 10, and the NOI comments must be received by no later than Oct. 25, the agency said.

Canada's National Energy Board (NEB) approved Alliance Pipeline Ltd.'s application for the BC Expansion Project (BCX), which is designed to enhance capacity for natural gas receipts originating at the existing Taylor Junction valve site in northeastern British Columbia. Alliance will not increase the mainline capacity of its system with this project, only the ability for existing shippers to increase gas nominations at receipt points in British Columbia. The additional capacity was made available to existing Alliance shippers through a binding open season in October, and Alliance has entered into contracts with the interested shippers. Start-up is scheduled for November 2008. To facilitate this expansion, Alliance will construct C$30 million of compression and ancillary facilities to increase capacity to receive gas supplies on its Taylor-Aitken Creek lateral system. At the request of the NEB, Alliance will be conducting a second open season at an as-yet undisclosed date to determine any additional interest in this newly approved service.
