Springfield natural gas customers could see their gas bills getting higher. A commission of Springfield City Utilities has recommended that the Heating Expense Leveling Program (HELP) be ended early. City Utilities manager John Twitty says there was a good reason for calling for a premature end. Namely, the money involved is getting too large. He says the HELP program was scheduled to end in March. Twitty says there is some good news in that natural gas prices seem to be leveling off, anyway.
